麻黄素

However, my favorite ephedrine-type effect of this second new amine that is characteristic of Ephedrine is bronchdiltation.

然而，我最喜爱的麻黄素型效应的第二次新胺所特有的麻黄素是

He was found to have traces of the banned substance, ephedrine, in his blood stream.

在他的血液中发现有违禁物质麻黄素的迹象。

To avoid these problem, stay away from products that contain Ephedra, Ma Huang, and Ephedrine.

为了避免这些问题，远离产品含有麻黄、黄马、麻黄素。

China is one of the major producing and exporting countries of natural ephedrine.

我国是天然麻黄素的主要生产国和出口国之一。

D: I'm giving you one bottle of ephedrine.

医生： 我现在给您开一瓶麻黄素。

The illicit synthesis of this compound has been achieved most commonly by the reductive amination of phenyl-2-propanone 2, by the Leuckart formamidation of 2 followed by hydrolysis or by the reduction of ephedrine or pseudoephedrine 3 with hydriodic acid and red phosphorus.

此化合物非法合成的方法有，通过1-苯基-2丙酮的还原胺化作用；通过1-苯基-2丙酮的洛卡特氐反应后进行水解生成；在红磷、氢碘酸的参与下，通过还原麻黄素或伪麻黄素合成。

II. The State practices the special-purpose control system with respect to the production, management, use and export of ephedrine (including extracts from ephedra grass and chemically synthesized, laevorotatory and dextrotatory) as well as their saline categories such as ephedrine hydrochloride, ephedrine oxalic, ephedrine sulphate and raw products of ephedrine (including ephedrine extracts, ephedrine extract powder and ephedra powder), ephedrine derivatives and prescribed preparations made with ephedrine as the raw material.

二、国家对麻黄素(含从麻黄草提取和化学合成的，包括左、右旋)及其盐类如盐酸麻黄素、草酸麻黄素、硫酸麻黄素和麻黄素粗品(含麻黄浸膏、麻黄浸膏粉、麻黄草粉)、麻黄素衍生物以及以麻黄素为原料生产的单方制剂等的生产、经营、使用、出口实行专项管理制度。

The aim of this work is to simultaneously identify the major impurities, it's concentration and optical isomers in MA samples. Gas chromatography/mass spectrometry with selected ion monitoring was employed after drugs were derivatized with--α-methoxy -α-phenylacetic acid.

本实验的目的，就是利用气相层析质谱仪配合化学对掌性衍生剂--α-methoxy-α- phenylacetic acid，以选择性离子侦测模式来进行分析，检测甲基安非他命中所残留的麻黄素与伪麻黄素的含量与旋光性。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
