Meanwhile, fundamental principles about electroless tin plating by reducing agent and disproportionation reaction were explained. function of every component in the bath was explained that complexing agent can effectively change the potential of copper and tin, and accelerate the beginning of replacement reaction favorably ; reducing agent can increase the rate of chemical reaction and has the effect of promoting reaction dynamics too ; antioxidant can effectively prevent sn2 + in the bath from being oxidated ; additive agent a can improve the stability of the bath ; additive agent b has such effects as refining and brightening for the tin deposits, and it enlarges the range of brightening section ; additive agent c used as leveling agent can not only make the depostis level off, but also improve the dispersive ability of the bath ; surface - active agent can solve bubble problem which gathered on the surface of the deposits, and improve the surface quality of the deposits and the bath stability
闡述了鍍液中各組分的作用：絡合劑能有效地改變銅、錫的電位，促使初期的置換反應順利進行；還原劑能加快化學反應速度，對反應動力學有積極的促進作用；抗氧化劑能有效地防止鍍液中sn ~ （ 2 + ）的氧化；添加劑a能提高鍍液的穩定性，添加劑b對鍍層能有細化和光亮作用，擴大了鍍層光亮區的范圍；添加劑c作為平滑劑，不僅能增強鍍層表面的平整性，而且能提高鍍液的分散能力；表面活性劑較好地解決了化學鍍過程中汽泡在鍍件表面聚集的問題，提高了鍍層的表面質量和鍍液的穩定性。 -
Group division : experiments were performed in 3 different conditions, i. e., normal 4 medium, high k * stimulated medium, and ca2 + - free medium. hippocampal slices from a same rat were then divided into 3 treatment groups : control group ? lices were oxygenated with 95 % o2 / 5 % cc > 2 and incubated at 35 ~ 36 ? for 30min ; hypoxia group ? lices were oxygenated and incubated on the same conditions as the control group, then the mixture gases change into 95 % o2 / 5 % co2 - hypoxic condition were remained for lomin ; ginkgolide b preincubation group ? lices will be preincubated at the normal oxygenated medium containing loomm ginkgolide b, 10 min later, repeated hypoxic treatment
3實驗採用隨機區組設計，動物隨機分為三組，各組動物制備的海馬腦片分別進行三種不同介質的灌流實驗，即正常介質組、高k ~ +去極化組和無ca ~ （ 2 + ）組；各組中由同一隻動物製成的海馬腦片再隨機分到三個不同的處理組，即：正常對照組、低氧組和ginkgolideb預孵育組。 -
B : no, let ' s go surfing for a change
不，我們換個玩法去沖浪吧。 -
B ： yes. nice and sunny for a change
是呀，總算風和日暖了。 -

員工著裝要求：在轄區內乙方工作人員必須按甲方要求的標準式樣統一穿著工作服、工作鞋及工作證，按球會草坪部的標準要求統一換洗工裝，保證工裝整潔。 -
This provide a basis for further application such as feature editing and so on. unlike traditional method which modifies b - rep or csg to adapt feature - based modeling, the feature - based represent model for the product which based on identifying system is presented. the represent method need not change the b - rep of solid model and can map feature - based model to b - rep - based model
不同於通常的對邊界表示法或csg法進行改造的模型表示方法，提出了一種基於標識子系統的特徵表示模型，一個零件的特徵表示模型和其低層的幾何實體模型通過標識子系統進行映射，從而不必修改現有的邊界表示模型而能滿足特徵造型的需要並能充分利用已有的實體造型功能。 -
Paper [ 76 ] provides a integer algorithm for rasterizing free curves, we need change the curve form to implicit function form, then use curve ' s positive - negative property to draw, but we ca n ' t use this algorithm when curve ' s degree is higher than 3 and this algorithm ca n ' t avoid using multiplication ; paper [ 77 ] provides a new generating algorithm, this algorithm can draw bezier very well, but for b - spline curve, we need use convert them into bernstein base form. because this process spends a lot of time, this algorithm has not a good speed and effect for rendering rational b - spline curve
現在經常採用的演算法也是基於幾何的演算法（即線式生成演算法）和基於像素的演算法（點式生成演算法） ;文獻78 ]提供了一種有理參數曲線的快速逐點生成演算法，該演算法對有理b吮ier曲線的繪制，能起到很好的作用，但是對于有理b樣條曲線，必須先通過多項式的代數基與bemstein基間的變換矩陣，把原式用bemstein基表示，這一過程由於計算量大，降低了曲線生成的速度和效率 -
If party b is requested to move out because of the change in ownership of the premises, party a should inform party b in writing of the movement three months beforehand, be responsible to arrange relevant premises for party b ‘ s use and compensate party b a sum equivalent to two months ‘ rent of the leased premises for the movement losses
