The reaction proceeded in xylene at 120 ℃ for 10 h to give bromoxynil octanoate in 91% yield.

以DMF、三乙胺为催化剂，在溶剂中，用辛酸直接合成了溴苯腈辛酸酯，实现由酸合成酯的一步反应。

The result indicated that, gathers in advance the emulsion water resistance and mechanics performance which in the body preparation method the one-stage process obtains is good, but two steps obtain the emulsion stability is good; The neutralizaing agent triethylamine amount used should enable to achieve neutral between x-y, to gathers in advance the body disperser and the emulsion stability only then is advantageous; The water affinity chain extendor DMPA content to the emulsion viscosity, stable and the emulsion cellophane water resistance has the remarkable influence, its amount used general control between x-y; Hard section isocyanogen diethylene glycol dinitrate primary control paint film degree of hardness, module, anti-avulsion, wear-resisting and so on performance, the soft section low-molecular polymer polyols primary control paint film elasticity, hydrolisis performance and so on bears the low temperature and bears

结果表明，预聚体制备方法中一步法得到的乳液的耐水性和力学性能较好，而两步法得到的乳液的稳定性好；中和剂三乙胺的用量应使中和度达到x-y之间，对预聚体的分散和乳液的稳定性才有利；亲水扩链剂DMPA的含量对乳液的粘度、稳定性及乳液胶膜的耐水性有着显著的影响，其用量一般控制在x-y之间；硬段异氰酸酯主要控制涂膜的硬度、模量、抗撕裂、耐磨等性能，软段低聚物多元醇主要控制涂膜的弹性、耐低温和耐水解等性能

The dehydration of sulphonyl derivatives of N-alkylformamide using phosphorus oxychloride in the presence of triethylamine at 0-10℃ provides a useful method for the preparation on sulphonylmethyl isocyanides e.g.

光气同三乙胺或是嘧啶是一组有效的制取异氰基化合物的试剂，但是，由于光气在安全性方面的问题它不适宜在大规模上制取异氰基化合物。

Only one event, a grade 3 cutaneous reaction, was deemed to be related to the study drug – and that was to ethambutol, not moxifloxacin.

其中只出现一次3级皮肤反应，被认为与本研究中的药物有关，并且发生于乙胺丁醇组而非莫西沙星组。

Compared with control patients who received ethambutol, more patients who received moxifloxacin were culture negative after just 1 week of treatment.

与使用乙胺丁醇的对照组病人相比，在使用莫西沙星后仅一周，很多病人的结核杆菌培养已呈阴性。

We have developed a modified molecular beacon melting curve analysis for rapid screening of Ethambutol drug resistance and multi-drug MDR resistance tuberculosis.

本论文发展了一种利用改良分子信标的熔解曲线分析技术对肺结核的乙胺丁醇耐药和多药耐药突变进行快速筛查的方法。

This potential hazard must be taken into consideration whenever ethambutol is priscribed.

无论何时开出乙胺丁醇，都必须考虑这一潜在的危险。

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。
