Occasionally, customs agents accepted large tips from Teabing in exchange for turning a blind eye to the transport of harmless organics—mostly luxury foods—French escargots, a particularly ripe unprocessed Roquefort, certain fruits.

这里的海关工作人员不时会从提彬那里得到大笔的小费，作为交换，他们对他从外地运来的无害有机化学物——其中多半是些奢侈食品，如法国食用蜗牛，特别是宜于食用但尚未加工的羊乳干酪，还有一些水果——睁一只眼闭一只眼。

The necessity and feasibility of this experiment synthesizing 7-(4-Antipyringlazo)-8-Hydroxyquinoline-5-sulfonic acid and its color development reaction with copper were investigated.

新实验在培养学生有机化学实验基本技能的基础上，着重培养了学生的研究探索能力和创新能力。

During the Great Proletarian Cultural Revolution, a "three-in-one" combination research group was organized from the workers, which formed the main-force, cadres and technical staffs of Silicen-Steel Sheet Works, Metallurgical Designing Institute and a research institute, for the recovery of sulphuric acid from the waste acid liquor of the steel works.

在无产阶级文化大革命中，由上海矽钢片厂、上海冶金设计院及中国科学院上海有机化学研究所组成的以工人为主体的工人、干部、科技人员三结合试验小组，对硅钢片酸洗废液通过用S-203强碱性阴离子交换膜扩散渗析法进行硫酸的回收，既节约物资，又改善环境，获得了较为满意的结果。

In this paper, an approach to two problems in organic chemical teaching was made:(1) Determination of the type and the number of Cis-trans isomers of acyclic alkenes;(2)An easy way to convert a Fischer Projection into a zigzag representation.

对如下两个有机化学教学问题进行了探讨：(1)如何确定链状多烯顺反异构体的数目和类型；(2)单糖的Fischer投影式转变为透视式的简便方法。

The Barbier-Type reaction is one of the most important methods for the construction of carbon-carbon bond in organic synthesis.

构建碳-碳键的反应在有机化学中一直处于非常重要的位置。而Barbier-Type反应又是其中最重要的反应之一。

Unfortunately, bad rate capability at heavy current rate and low tap density of Li4Ti5O12 are the main impediments to commercialization .
