没有鎚子很难测试钉好的peg，但有一个合理的测试方式，用两只指头松松地拿著钩环，在peg上轻拍，发出的声音会指出安全与否。

Without a hammer it is difficult to test a fixed peg but a reasonable test is to loosely hold a krab in two fingers and tap it on the peg, the sound it makes will indicate whether it is safe.

没有鎚子很难测试钉好的peg，但有一个合理的测试方式，用两隻指头鬆鬆地拿著鉤环，在peg上轻拍，发出的声音会指出安全与否。

The replacement of toxic and volatile organic solvents as reaction media or an efficient catalyst with environmentally acceptable alternatives are an area of tremendous importance in modern organic synthesis. Basing the review about solid-phase synthesis with simple separation, the liquid phase organic synthesis supported by the solution polyethylene glycol and the chemical reactions in the medium of PEG, herein we are going to study the synthesis of 1-amidoalkyl-2 -naphthols in presence of the solution catalyst or the solid catalyst and the synthesis of thiourea in PEG-400 medium.

难溶性载体试剂参与下的固相合成使分离操作简单易行；可溶性聚乙二醇支载下的液相合成显示出液相反应的稳定高效性，同时兼顾大分子聚合物容易沉降分离的优点；无毒且稳定的小分子PEG作为反应介质，往往表现出醚和醇的双重性质和功能。
