| 1. | It is essential that all components are listed and that the weight percentages total 100 % , even if estimated
一个基本要求是将所有的成分都列明，重量百分比的总和应为100 % ，即使是估算的。 |
| 2. | The formula of cumulative weight percentage at different particle sizes , which was in the case of composite particle size distribution , was proposed
摘要提出了在矿砂粒径尺寸级配情况下，不同粒径的筛下累积含量公式。 |
| 3. | It ' s found doping effect is best under 40c temperature and that dbsd / pan weight percentage is 1 . 7 . at last resistiveity - temperature of cp is studied
结果表明：在40下，十二烷基苯磺酸/聚苯胺质量比为1 . 7时，掺杂效果为最佳。 |
| 4. | Under the condition of distilled water working as lubricant , the weight percentage of cu or cuo powder in composites has less influence on tribological properties of composites
在水润滑条件下， cu粉或cuo的填料含量对复合材料摩擦和磨损性能影响很小。 |
| 5. | The results in this paper show that the conductivity increases quickly when cf weight percentage is 0 . 3 - 0 . 8 % and turns to low after 0 . 8 % ; secondly , it indicates that thermal expansion is restrained by cf obviously
本试验结果表明当含量在0 . 3 0 . 8之间时，导电率迅速上升，当0 . 8含量以后，上升速度变缓。碳纤维的掺入对砂浆混凝土的热膨胀能够起到一定的抑制作用。 |
| 6. | The " of si3n4 - si / cyn composites increases with the increase of the content of si / c / n nano powders when the weight percentage of si / c / n nano powders is less than 10 % . with the weight percentage of si / c / n nano powders increase from 10 % to 15 % , the " of si3n4 - si / c / n composites decreases
而复合材料的介电常数实部在si c n纳米粉重量百分比小于10时，随si c n纳米粉重量百分比增大而增大，继续增大si c n纳米粉的含量至15 ，介电常数实部反而下降。 |
| 7. | 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。 |
