The gap between designers ' interpretations and users ' understanding of product form is recognized as coding - this can be divided into two diametrical positions : encoding ( where signs are produced ) and decoding ( when signs are received ) 设计师诠释产品造形的原构想和使用者理解的结果，因为符号与符码的效应而有所落差，以相对应的两个角度来看，即为编码（产生符号）与解码（接收符号） 。

On the contrary , in these movements , scientific spirit was lost because science , instead of metaphysics in " technique and metaphysics : two extreme " structure , showed priori , absolutely correct , then in diametrical opposition to its nature . in view of culture conflict , cmse could be divided into two periods before " reform and open policy in 1978 " “科学”对“玄学”的挑战是获得了胜利，但是，在中国传统知识体系“技艺和玄学两极对立”的影响下，科学同时也具有了玄学的特征，科学知识被认为是先验、绝对正确而不容质疑的，这与科学本身的精神背道而驰了。

Abstract : it has been discovered that the coke formed in ch4 coupling under plasma can be eliminated via pure h2 discharge in the system . eliminating coke under plasma with positive or negative high voltage in dc electric field has been compared with that in ac field . the elimination of coke takes place only on the negative of the two electrodes in dc field , while on both electrodes in ac field . the coke on the reactor walls can be eliminated with either positive or negative high voltage and in either dc or ac field . based on the experimental facts , hypotheses of the reaction mechanism are suggested . quantity of eliminating coke depends on diametrical ratio between reactor and the electrode , input power and electrode materials 文摘:发现了等离子条件下甲烷偶联反应中形成的积炭可以通过该体系中纯氢气放电而消除.将消除积炭使用直流电场的正高压和负高压与使用交流电场作了比较,发现直流电场中无论使用正高压还是负高压,只有阴极上的积炭可以被消除,而交流电场中两极积炭均可被消除,反应器壁上的积炭在以上任何情况下均可被消除.基于实验事实提出了机理假设.消除积炭的量与输入功率、反应器对电极的直径比以及电极材料有关
