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。Measuring cylinder is used on test bench of fuel injection pump all over the world, so manufacture error, sight error etc make the accuracy degree low. the thesis analyses the problem of fuel measurement system of the test bench of fuel injection pump, and the experiments and designs are done according to the problem, and the type and situation of the test bench of fuel injection pump all over the world is refered to
目前國內外噴油泵試驗臺量油系統普遍採用量筒式計量法，該方法存在量筒的製造誤差、沉積誤差、液面讀數誤差、氣泡誤差、揮發誤差以及測量人員的視覺誤差等，使得測量精度較低、耗時長，已不能滿足對汽車發動機的環保技術要求和節能要求。Series bulb, for forms a complete set or system in the various big autom - obile motorcycle factory of the whole nation, also is chinese automobile

佛山市南海羅村陽星照明電器廠，位於廣東省南海區羅村鎮蘆塘工業園，緊靠桂丹公路旁，仳鄰佛山沙堤機場，本企業專業汽車燈泡，摩托車燈泡生產及銷售的企業，品種齊全，質量好，檔次高，信譽好，深受國內外客戶歡迎。The paper is on how to set up lab platform of vapour spewing to uppercooling water surface to coagulate directly and to observe and analyse which vapour coagulate on the water surface, the results enable people to know the security system of nuclear power. the range of the pressure parameters of prz is from 0. 2mpa to 0. 6mpa, and the range of the initial temperature parameters of cmt is from 23. 5 to 78. 5, all of the testing points are 30 and there are fifty thousand testing data. many results of vapour spewing to uppercooling water surface vertically to coagulate can get. for example : coagulating can make the water of cmt surge forcefully when vapour spews to uppercooling water surface, too many vapour - bubbles come into being and strike the water of cmt owing to rupture continually, all these will strengthen the surge because of the vapour pressure of cmt
實驗中prz飽和蒸汽壓力變化范圍為: 0 . 2mpa - 0 . 6mpa ， cmt中水初始溫度變化范圍: 23 . 5 - 78 . 5 ，實驗中測試工況30個左右，實驗測試數據50萬余個，得出了很多與非能動安全系統相關的蒸汽垂直噴向過冷水表面凝結時的結論：蒸汽垂直噴入過冷水表面凝結時會造成cmt中液面的強烈波動和振蕩，產生大量蒸汽汽泡，汽泡不斷破裂對cmt中液體帶來很大沖擊，勢必引起cmt中液體的振蕩，造成cmt汽空間汽壓不均勻，加強cmt液體的振蕩和波動。This factory professionally produces various mini - colour lamps, christmas decorative lamps, automobile audio lighting lamps, lamps for clocks, watches and flashlights, etc. the companyhas strong technical strength, advanced equipment and complete testing facilities
