positive excess 中文意思是什麼
positive excess
解釋
正電荷過剩-
Meanwhile, it was detected that the excess a13 + ions, to compensate the positive charge caused by the substitution of partial mg " ions by ti ions, occupy the t2 site in the six - membered rings in the sample of 1. 8 mgo 0. 2tio2 2. 2 a12o34. 6sio2
2tio2 ? 2 . 2al2o3 ? 4 6sio2中用作價態補償的過量al3 +全部進入六元環t2位宜上。 xps的研究發現， zn 『 」 、 t廣的同溶使繭青石結構中的川、 st等元素出現了多種化學狀態。 -
Similarly, either an addition of positive charge or a removal of negative charge will result in an excess positive charge.
加入正電荷或移出負電荷，都將同樣地導致過剩的正電荷。 -
A lot of experiments have been done in the process of exploiture soft packaging li - ion battery about how to choice the rational arts and crafts. the content include : how to deal with the collector, add how much pvdf in the material, how long the material need to stirring and the right viscidity, how much condubtivity agent the electrode need, what theckness is best, choice different collectors, the degree of dryness of the electrode, theckness of pressed model, how much electrolyte will be added, placement how long after added the electrolyte, system of formation how to influnce the battery, in formation the battery need or not need preesure from outside, how to vacuumize and the optimize matching positive pole and negative pole. with these practice make sure the parameter of the positive pole should less than 90 m ; according to different vacuumize order the conduc - tivity agent in anode will be 5mass % and 9mass %, respectively, and in cathode the data is 2mass % ; every 100mah added to 0. 4 ml electrolyte ; before formation the battery should be placement 8 hours and the system of formation must be less than 0. 01c before the voltage reach to 3. 0v ; should press in outside when battery in formation ; to these batteries which capacity more than 350mah the vacuum time not excess 15s ; the optimize matching positive pole and negative pole between 2. 10 : 1 and 2. 15 : 1. finally make out the battery which cycling performance and security are all very well
液態軟包裝鋰離子電池的研究主要是對關鍵工藝進行了優化設計，具體包括:集流體的處理、 pvdf的加入量、漿料攪拌時間和粘度、導電劑的加入量、電極膜的厚度、不同集流體的選擇、電極膜的乾燥程度、壓型的厚度、電解液的加入量、注入電解液后靜置時間的長短、化成制度的影響、化成時電池所具有的壓力影響、抽真空的處理、正負極活性物質的匹配。最後確定出液態軟包裝鋰離子電池最佳工藝參數:正極膜的厚度小於90 m ;根據化成時不同抽真空順序，確定正極膜中的導電劑的加入量分別為5mass %和9mass % ;負極膜中導電劑的加入量為2mass % ;電解液的加入量為每100mah添加0 . 4ml ;化成前電池的靜置時間應當大於8h ;電池在3 . 0v之前採用小於0 . 01c的化成制度;在化成過程中應當施加一定的外部壓力;對於350mah的電池抽真空的延時不應大於15s ;而正負極活性物質的質量比應當在2 . 1 : 1 2 . 15 : 1之間。 -
The salt crystal lamp binds the negative ions with the excess positive ions
鹽晶燈可中和負離子和過多的正離子。 -
A positive analysis of the excess employee, government interference and technical innovation of soes in china
政府干預與國有企業技術創新的實證分析 -
Ipo underpricng is referred to an average excess return, statistically significantly positive, of a new issue immediately aftermarket relative to its offering price. a common perception is that underpricing is a challenge to market efficiency at least apparently
所謂新股發行抑價，是指首次公開發行的新股上市后，其二級市場價格相對一級市場發行價格，在統計上所存在的顯著為正的平均超額收益。 -
In essence, the indexing investment is a passive investment strategy, and corresponding to the positive investment which is through active research and analysis ( including technical analysis and fundamental analysis ) to achieve excess return of stock market
從本質上講，指數化投資是一種被動投資（ passiveinvestment ）策略，而與之相對應的積極投資（ activeinvestment ） ，則是通過積極的研究和分析（包括技術分析和基本分析）來選股和擇時以獲得市場超額收益的一種投資模式。
