查询词典 tweezer

Eleven molecular tweezer artificial receptors based on deoxycholic acid have been synthesized by using solid K2CO3 as supporter through the reaction of methyl deoxycholate with aroyl chloride in solvent-free conditions under microwave irradiation, five of which are new compounds. The structures of all the molecular tweezers were characterized by 1H NMR, IR, MS spectra and elemental analysis.

在微波辐射无溶剂条件下，以固体K2CO3为载体，脱氧胆酸甲酯与芳酰氯反应合成了11个脱氧胆酸分子钳人工受体，其中5个为新化合物，所有化合物的结构均经1H NMR， IR， MS及元素分析所确证。

The other method to improve the efficiency for the optical tweezer is to change the microrotor's configuration. The results show that rotor speed of the microrotor is about 10^(-7) as large as that of the cross-shaped rotor.

另一种可以大幅度提高光镊工作效率的方法是改变微转子的形状，数据表明&万字&形微转子的转动效率是相同尺寸的&十字&形转子转动效率的10^(-7)倍。
