Chinese Cinnamaldehyde which also named Cinnamaldehyde alias, is the main component of volatile oil which obtained by steam distillation from dry skin and cinnamon bark of lauraceae plants . It is researched as a root canal sterilization drug in recent years, it can seriously undermine the bacterial cell surface structure, and thus has a wider antibacterial spectrum and strong antibacterial activity; gallnut hundred, also known as worms, it is a kind of gall that be formatted by Schlechtendalia species of insects including Schlechtendalia and times aphid eggs in their parasitic plants Anacardiaceae Rhus chinensis, Green bran Yang or red bran Yang, the main ingredient for gallnut tannin, can solidification microbial protoplasts and a variety of body enzymes, a wide range of bacteria, fungi, yeasts are inhibited.

中药桂皮醛别名肉桂醛，是樟科植物肉桂的干皮及树皮经水蒸气蒸馏得到的挥发油中的主要成分，是近年来研究较多的根管消毒药物，它能够严重破坏细菌细胞表面结构，从而具有较广的抗菌谱和较强的抗菌活性；五倍子又名百虫，是倍蚜种昆虫角倍蚜或倍蛋蚜在其寄生漆树科植物盐肤木、青麸杨或红麸杨等树上形成的虫瘿，其主要成分为五倍子鞣质，能够凝固微生物体内的原生质及多种酶，对多种细菌、真菌、酵母菌都有明显的抑制作用。

The high purity of 2-mercapto-β-naphthothiazole was obtained with α-naphthylamine as raw material via reaction of seal glass tube, alkaline extraction, vapor distillation, acidification of acetic acid and ethanol recrystallization.

以α-萘胺为起始原料，通过封管反应、碱提取、水蒸气蒸馏、乙酸酸化和乙醇重结晶，取得了纯度较高的2-巯基－β-萘并噻唑。

In addition, our works also indicate that MC-ICPMS technique shows a good potential on Re-Os isotopic measurement. 2. A new method for the determination of low Re-Os abundances and ~(187)Os/~(188)Os in a natural rock sample by MC-ICP-MS has been established in our laboratory. Rock samples were digested in inverse aqua regia in sealed Carius tube for 24 hours at 230°C, then Os was separated from the matrix by CCl_4 solvent extraction, and further purification by microdistillation.

建立了Re-Os同位素样品的化学分离和纯化方法以及MC-ICPMS质谱测定方法：岩石样品的Re和Os化学分离方法是采用Carius管溶样法，结合四氯化碳萃取以及氢溴酸反萃取的方法分离出Os，最后是通过微蒸馏的方法纯化Os；利用阴离子交换树脂的方法分离纯化Re。

Continue the distillation for 5 minutes, then remove the heat, and allow the receiving tube to cool to room temperature.

继续蒸馏5分钟，移走热源，让接收管放冷至室温。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
