  1. 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。
  2. In addition, impact of superplasticizers to hydration procee were discussed thoroughly. results showed that superplasticizers improved cement hydration process. initial hydration of cement was accelerated by superplasticizers because of their high range water reducing and dispersive action. after that, hydration rate was descended as a result of more initial hydrates and absorption of superplasticizers

    高效減水劑由於其高度減水分散作用，水泥初始水化速度加快，但其後由於減水劑分子的吸附及初期水化產物膜的增厚，水化速度降低，從而有利於漿體結構的密實與後期性能的發展。
  3. Because the harmonics in tangyin substation are primarily from electric traction loads, this paper gives the structures of several main locomotive models and general harmonics they produce. the harmonics produced by electric locomotive have a characteristic that their range and phase are both dispersive. this paper also analyzes the impedance - matching balance transformer ' s structure and harmonics injected into the power system at its primary side, and sums up the characteristics of the harmonics from electric traction loads in the tangyin traction substation

    鑒于湯陰變電站的諧波主要來自電力牽引負荷，本文列舉了電力機車幾種主要車型的結構以及它們產生諧波的概況，得出了電力機車的各次諧波電流幅值和相角具有較大分散性的特點。針對湯陰牽引變電站的牽引變壓器，分析了阻抗匹配平衡變壓器的結構及其高壓側注入電網的諧波，推導了有關計算公式。通過理論分析並結合湯牽線的實測諧波數據，歸納了電力牽引負荷注入湯陰變電站的諧波的特點。
  4. In addition, for a dispersive high frequency system, because of the requirement of the phase in - step between the beam and electromagnetic wave, the bandwidth are expected to be located in a narrow range

    另外，對干填充等離子體的色散高頻系統，由干電子注和電磁波互作用的同步要求，系統帶寬必然分佈在某一有限范圍內。
  5. In this paper, theoretical models for kinetic study of chromatography in recent years is summarized and several kinds of models used commonly are described such as general rate model, lumped pore diffusion model, equilibrium - dispersive model and transport - dispersive model, and their characteristics and application range are discussed

    本文對近年來色譜分離動力學研究常用理論模型的發展進行了綜述，重點介紹了普遍化速率模型、集總孔擴散模型、平衡擴散模型和傳遞擴散模型4種常用的色譜模型，並討論了各模型的優缺點及應用范圍。
  6. This type of configuration has the advantages of better energy resolution at longer wavelengths ( soft x - ray and light elements ) and a much larger dynamic range than the energy dispersive method
