活性点 meaning in Chinese
active site
Examples
- By comparing the activation area of binary alloy with that of ternary alloy catalyst , the introduction of multi - metal alloy catalyst is found to be able to increase the number of activation site
比较二元合金催化剂同三元合金催化剂的活性面积，发现采用多金属催化剂还能提高活性点的数目。 - Wld is a high - temperature anti - sloughing agent , which contains si and organic compound ion . by applying it with polymer drilling fluid in the high - temperature deep well and the well section of heaving mud shale , it can improve the stability of drilling fluid dramatically . and at the same time , it can deactivate the drill cuttings and the wall surface active point to greatly improve the property of rejection and anti - sloughing of the drilling fluid through the physical - chemical action occurring between the special group of molecule vs . drill cuttings and the wall surface
Wld高温防塌剂是一种含有si元素和有机复合离子的抗高温防塌剂，在高温深井及易垮塌的泥页岩井段配合聚合物钻井液使用，不仅可以显著改善钻井液的稳定性，而且可以利用分子中的特种基团与钻屑和井壁表面发生物理-化学作用，使钻屑和井壁表面活性点钝化而显著提高钻井液的抑制防塌能力。
