PI system has become a business or management an important part of the information integration system, directly applied to operation, maintenance and management integration. For production process control and business operations and management of real-time information exchange between systems has set up a bridge. PI System can be directly collected more difficult to obtain a variety of real-time operation real-time data (usually the class data, enclosed in the self-contained automated system or manual data sources), and turn it into public, and effective information on the business. Regardless of industry or management, are available from these key benefits of real-time information access and business areas in the dynamic free ride to reach performance goals. 3. PI database system to accelerate the return on investment of users PI system construction will produce practical results quickly, and in business to help customers achieve ever-increasing benefits. PI system provides reliable data and clear. Meanwhile, PI system installation cycle is short, configure integrated into the user's production management systems, business monitoring / control systems, information systems, decision support process, and no need to change the user the original system. PI system through a standard interface for library expansion, able to connect hundreds of different operating modes of the process monitoring system or automatic operation system. Also, by using the COM connection technology, making the PI to achieve with existing or future customers need to increase the effective integration between databases. PI system, a powerful application services and client tools, but also ensure that the customer convenient use, easy to operate. PI system can provide users with the needs of their business critical data and real-time information. Such information to the user in the production run, the system maintenance, cost control, quality management and follow-up services in the course are essential. Therefore, the use of PI database system, not only can significantly improve efficiency, reduce operating costs and resource depletion, and thus speed up the return on the investment of users. 4. PI database system security system architecture design PI system as a whole, have been considered and provides a complete integration of security mechanisms to ensure that the user data in use foolproof. PI system security mechanisms, already have fine to each data point security management, which include points on the database to read, write, or modify and so on. Therefore, anyone who wants to access any data in the PI database system users must first obtain the appropriate access rights to confirm. And the access configuration and management, only the system administrator has the core competence, and its also affected by identity management. Second, Price Index (price index) price index, said in a given period of time, the average price of a commodity to changes in an index. In calculating the average number of different commodities prices in general to be weighted according to their economic importance of treatment. (For example, in calculating the consumer price index, weighted according to each commodity in total consumption is the share of expenditures.) Reflect the different periods of the direction of commodity price levels, trends and levels of economic indicators. An economic index, usually the reporting period and the relative ratio of the base period expressed as relative number. Price index is to study the price dynamics a tool for the development, adjustment and inspection of various economic policies, in particular, provide the basis for pricing policy. Historical Price Index for the preparation of the history of earlier. 18th Century English and some European and American governments and economists began to engage in price index theory and application. With the development of capitalist economy, the late 19th century early 20th century, the world wide price index is compiled and applied. China officially in 1920, the price index. Nankai University in Tianjin in 1927 prepared and published wholesale price index in North China, and later compiled and published a series of price index. These include: 1867 to 1937 the volume of import and export price indices, 1913 to 1952 the wholesale price index in North China and Tianjin in 1926 to 1952 the cost of living index. National Government in 1926 as the base, the preparation of a more systematic, wholesale price index. Guangdong Province in the early 40's retail price for the main statistics, Beijing and Shanghai, also in 1926 as the base, the preparation of a systematic price index cost of living of workers. Price index by category, including the scope of its divided into: ① the individual index, a commodity price levels reflect the degree of index movements; ② class index, the classification of commodity price index, reflecting the movements of a commodity price level index of the degree ; ③ index,
chi pink dazzle limited edition, reflecting the full extent of lifting the general level of commodity prices index. Price index according to the calculation used the base period of the difference can be divided into the chain price index (above a base period), annual from the chain price index (over the same period as the base) and the fixed base price index (in a fixed period for base period). China's commodity price index by type of case, there are producer price index, price index of agricultural products, service items price index price index cost of living employees; by the circulation of goods and distribution channels distinguish between the wholesale price index and retail price index, index of state-owned commercial premiums, negotiated commodity price index, price index and trade fairs including the premium, super-purchase fare, a variety of price bargaining and the market index; distinguished by the difference between urban and rural areas, there are urban and rural price index price index . Third, Propidium Iodide referred to as PI Propidium Iodide referred to as PI, propidium iodide Chinese name, molecular formula C27H34I2N4, molecular weight 668.40, can be used as nucleic acids (DNA, RNA) of the fluorescent dye. PI commonly used in cell apoptosis (apoptosis) or necrosis (necrosis) in the detection and flow cytometry. PI can not be through normal cell membrane, so the cells in late necrosis or apoptosis in the cell membrane is damaged, then the red for the PI, can be used to distinguish necrotic cells / normal cells.

PI controller works: PI controller , the proportion of part P and the current measured temperature is proportional to the integral part of the previous measurements and I was poor and expectations, these two numbers together as a control output to control the cooling speed. by adjusting the appropriate P, I can factor air-conditioning to achieve the fastest and most stable and stable at the set temperature. Role: input circuit and feedback circuit. VI, import and export special form of the word PI = Proforma Invoice invoice, pro forma invoice, pro forma invoices, the role of pro forma invoices: 1 . let customers know what to buy, quantity, unit price and total value of the number; 2. customers to apply for opening letters of credit or other payment documents. Proforma Invoice Proforma Invoice (PI) and is equivalent to quotation! Quotations can make arrangements for production? That trade is not too easy to do now? Proforma invoice signed by both parties only after the contract takes effect means! - But only contract becomes effective, will not necessarily arrange production - usually have to wait until after receipt of LC or prepayment arrangements for production! Proforma Invoice can not make arrangements after the production. It's another role for the contract to be used. be The two sides seal (stamp) to take effect! my British customers always like to use for the contract in the form of PI use, and when he will be paid upon receipt of deposit PI! forma invoice can also be used for other needs clearing the occasion. (1) for payment in advance, which requires cash payment before loading. (2) in the consignment, the export sales of goods contracts not identified, but on the hands of agents of agents, the pro forma invoice can be used as a potential buyer to purchase the guide. (3) If it is tender, the buyer in the form of invoices can be many competing suppliers in the sale at a reasonable price and conditions of a contract of sale. Seven, Principle Investigator of the abbreviations can be translated into academic researchers, academic leaders, for example: PI, or move certain research institute he is certain outstanding PI. Further reading: PI system is the modern science and technology activities in a form of organization it a certain academic leaders, properly equipped with manpower, equipment, capital and other resources. In this organizational unit, academic leaders in a position of supremacy, both the existence and continuing responsibility to maintain and development unit of the responsibility, but also with full power. (Stated, the information from the network) eight, PokerIdol DOTA abbreviation PI is one of the famous clan, during the last session of the SMM (called DOTA World Cup) in the CH and other teams beat the teams EHOME China was the opening game of the group broke 5VS5 war, and the once-leading 11:0, unfortunately finally EHOME comeback, played a very good game nine, Pi (inorganic phosphate) in the organisms, phosphorus is the solution in the form of free phosphate ions, which is called Pi inorganic phosphate is the will to express, it is a pyrophosphate (PPi expressed by) the hydrolysis derived: Figure:
However, the most common phosphate is adenosine monophosphate ( AMP), adenosine diphosphate (ADP), adenosine triphosphate (ATP), deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) forms, and can be hydrolyzed by ADP or ATP was released. For other nucleoside diphosphate or three also have similar P response. In the ADP and ATP, or the other two and three phosphorus phosphorus phosphorus anhydride bond in the nucleoside contains a lot of energy, so they are in biology plays an important role. They are usually referred to as high-energy phosphate bond, as in the muscle as creatine phosphate. Some, such as phosphorus compounds in organic chemistry will also be used, but it seems to be no natural counterpart. Because of the importance of phosphate on the biological, so in ecology, it is highly to be collected. Therefore, it is often limited in the environment, reagents, and its availability is determined by the rate of biological growth. Add the lack of a large number of phosphate in the phosphate environment or microbial environment has a significant impact on the ecological. For example, a make up an organism's waterfall death of other organisms, and certain biomass will reduce the lack of resources such as oxygen,
cheap chi flat iron, etc., etc. (see eutrophication). In the pollution problem, the phosphate is the total dissolved solids (a major water quality indicators) of the main ingredients. Ten, Polyimide (PI) PI referred to as a special project of polyimide material, have been widely used in aviation, aerospace, microelectronics, nanotechnology, liquid crystals, membranes, laser and other fields. Recently, countries in the polyimide research, development and utilization included in the 21st century, one of the most promising engineering plastics. Polyimide, its synthesis in performance and outstanding features, whether as a structural material or as a functional material, and its great prospect has been fully recognized, known as a ; (protion solver), and that November, personal income (Personal Income) payment of factors of production and national income in the sense of personal income will not all become. Subtract the company retained earnings from the national income, corporate income tax and social insurance tax (fee), plus the government transfer payments to individuals, in general to be personal income. Individuals in a country within a year all income received. Individuals from a variety of ways the sum of the income received, including wages, rental income,
chi pink dazzle hair straightener, dividends, dividends and social benefits made to the income received. Reflect the real purchasing power of the individual level, indicating the future consumers of goods, services, changes in demand. Personal income index is to predict an individual's spending power, the future trend of consumers buying the good and bad economic situation and evaluate an effective indicator. Second, PI principal investigator of clinical trials of drugs called PI principal investigator referred to thirteen, the U.S. drama The Pope offered FOX RIVER, want to hire prisoners of labor in order to play the role of change. Berwick but was making money for their own use of the tool. He sold the rights of persons employed Abruzzi. XIV. Isoelectric point isoelectric point (pI, isoelectric point) isoelectric point: at a pH of the solution, the amino acids dissociate into cations and anions of the trends and are equal, zero net charge brought, was in power ######, this time the solution pH is called the isoelectric point of amino acids. Zwitterionic charge carried by the solution pH, due to different changes in value when the ######es are equal positive and negative charge ions, pH value of the isoelectric point. When the external solution pH is greater than the pl value of zwitterionic, amphoteric ion release of protons with a negative charge. When the external solution pH is less than the pl value of zwitterionic, zwitterionic positively charged proton.
