    分析直流工作條件下，以氬氣、氮氣、氦氣為工作氣體時，氣體的壓強、極間距對著火電壓和管壓降的影響，並製作低氣壓（ < 10pa ）下的氣體放電開關管（放電氣體為氮氣和氦氣，極間距為5mm ） ，研究其在直流和脈沖下的放電特性，以及放電過程對電極的影響。
  2. Abstract : a semi - analytical method is used to modelling the pract ical 3 - zone simulated moving bed chromatography ( smbc ) process for optimal searc hing. the switch time which is the most important operation parameter of 3 - zone smbc is analyzed based on the nonlinear batch chromatography theory firstly, and then adjusted by the deviation between the output and the expectation. the switch time approaches the optimization very soon by continously searching on the basi s of the theory. the parameters of the practical system are inputted into simulat ion, the result is used in our experiment and a good separation is obtained

    文摘:針對三帶模擬移動床色譜的實際模型，用一種融合了前饋與反饋的半解析優化計算方法對三帶模擬移動床色譜過程進行了模擬.首先，由非線性單柱色譜理論解析地給出一個三帶模擬移動床色譜的主要操作參數即切換時間值，然後利用所得結果與目標量之間的偏差來校正切換時間，在理論指導下進行優化搜索，切換時間能很快達到最佳值.將測得的系統參數引入計算，並將計算結果用於實際操作，得到了很好的分離效果
  3. Abstract : based on set up a three - section simulated moving - bed system, the separation process and principle and the effects of the main operation parameters of the b - type three - section smbc are analyzed carefully. the switch time and the column asymmetry are discussed. these analysis were proved by the actual separation experiments of biphenyl and fluorene on the smbc system
