光亮剂

On the basis of electroplating and immersion plating tin, and through large numbers of experiments, a new process of electroless plating tin in acid chloride bath solutions including SnCl2 2H2O, NaH2PO2 H2O, special complexing agent, additive agent, stabilizing agent and antioxidant, was established.

本文是在电镀锡、浸镀锡工艺配方的基础上，通过大量的试验，确立了一种以氯化亚锡、次亚磷酸钠和特定的络合剂、添加剂、稳定剂，抗氧化剂为基本镀液组成的酸性氯化物化学镀锡体系，成功地在铜上实现了锡的连续自催化沉积，获得了性能优异的半光亮银白色锡镀层。

Bright and quick-drying near the middle-load operation in the short term anti-rust agent (such as less than or equal to 250,000 or about 60 days) under a good job.

接近光亮和快速干燥的中等负载防锈剂在短期运转（如小于等于250，000次或大约60天）下工作的很好。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
