求翻译：本实验首先进行表面活性剂的筛选，考虑抗盐、抗钙、界面张力等方面的原因，从实验室现有的几种表面活性剂中筛选出几种表面活性剂。是什么意思？

In this study, the first screening of the surfactant, consider the reasons of salt, anti-calcium, interfacial tension, surfactants screened from the existing laboratory surfactants.

This experiment carries on the sieving of the live of the surface first, considering the reason of the anti- salt,anti- calcium,the interface tension...etc., sieving a few with live surfaceses from the laboratory existing few with live surfaceses.

This experiment first carries on the surface active agent screening, considered anti-aspect and so on salt, anti-calcium, interfacial tension reasons, screen several kind of surface active agents from the laboratory existing several kind of surface active agent.

This experiment first screening of surfactant, consider salt-resistant, anti-CA, Interfacial tension, and other reasons, filtered out from the laboratories of existing surfactants surfactants.
