reduction of diameter meaning in English
直径减小
Examples
- In adding - acid system : the resistivities of different lithotypes " cp tend towards being constant and equal when weight percentage of aniline exceeds 50 % ; because of the structure difference of different lithotypes , the polymerizing places and processes are different ; the resistivities of vituain / pan and fusain / pan reach the lowest point respectively when ( ntloisiog / an is 0 . 6 , 1 . 0 ; the resistivities of cp decline fast and tend towards being constant along with the reduction of diameter of coal . in not adding - acid system : the resistivities of different lithotypes ' cp decline evenly ; it is found on the crossed experiment of cp , that ( nflsaog / an mole proportion is the most important factor to influence output ratio of cp and the weight percentage of aniline is the most important factor to influence resistivities of cp . according to the result of the crossed experiment of cp
在有外加酸体系中：苯胺百分含量大于50时，不同煤岩组分的电阻率趋于恒定和一致；由于不同煤岩组分结构上的差异，导致苯胺聚合场所和聚合过程的不同；当过硫酸铵/苯胺摩尔比为0 . 6 ， 1 . 0时，镜煤-聚苯胺导电材料电阻率和丝炭-聚苯胺导电材料的电阻率分别达到最低值；在无外加酸体系中：不同煤岩组分/聚苯胺导电材料的电阻率随着聚合时间的增加而均匀下降，并在8小时左右达到恒定；在对丝炭-聚苯胺导电材料进行的正交试验中发现：过硫酸铵/苯胺摩尔比对产率的影响最大，苯胺重量百分比对产率影响最小，而对产物电阻率影响最大的是苯胺重量百分比。
