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。 -
For this purpose, a simple method was proposed to simulate the progressive collapse behavior of a ship ' s hull girder subjected to longitudinal bending. in this method the cross section of hull girder is divided into small elements composed of a stififener and attached plating
傳統上，船體總縱強度是通過比較許用應力和在名義垂向波浪彎矩作用下甲板或船底上距中和軸最遠點的彈性應力來進行評估的。 -
It was found that before the plating, there is section time to gestating, that we call the " gestating time " and the plating was ended spontaneously after some time, named " plating time ". the analysis of the solution after plating indicated that the too much decrease of ph value results in the reaction to be stopped. the plating time was shortened when the ph and the temperature of the bath were increased
結果表明，鍍液ph浙江大學碩士學位論文范啟義2003年3月摘要值、施鍍溫度提高，由於反應的速度加快，使反應時間縮短；硫酸銅濃度提高，有助於加快反應速度，從而縮短反應時間； edta濃度提高，使鍍液穩定性升高，對反應時間的影響等效于硫酸銅濃度的降低；而甲醛濃度提高，雖然反應的速度加快，但由於可用於還原的量增加，因此反應時間增加；裝載量提高，因能鍍覆的表面積增加，使反應時間縮短。 -
This paper introduces application of electroless nicked phosphorus plating technique in the geermu refinery of the qinghai petroleum company located in a pleteau section and analyzes the problems and phenomena occurring in the application of the technique in the plateau section
