目前磷霉素的生产是通过以Na2WO4为催化剂、在乙醇中以30%的H2O2将顺丙烯膦酸环氧化得到消旋产物，再利用α-苯乙胺进行拆分而得到[2，3]。

Low molecular weight mannuronic acid, guluronic acid and κ carrageenan were prepared from algin and carrageenan by the acid hydrolysis method, and their weight average molecular weights and the distribution widths of molecular weight were determined by high performance gel permeation chromatography respectively.

本文以褐藻胶和κ-卡拉胶为原料通过酸水解分别获得了低聚的甘露糖醛酸、古罗糖醛酸和低聚κ-卡拉胶，并采用 HPGPC法测定了这 3种低聚糖的重均分子量。在此基础上再经硫酸酯化和成盐修饰制备了各自的硫酸酯碱式铝盐。

ABSTRACT : Objective Through the review v alid ation, the opinions and suggestions about production and quality management were put forward.

目的 通过再验证，提出对生产和质量管理的意见和建议。

A complex sample containing BMP and sodium fluoride was implanted under the abdominal skin of young male Wistar rats. The histiological characteristcs, and activities of alkine phosphatase and acid phosphatase of the implantan were examined to study the effects of fluoride on biological activities of BMP.

在纯化的BMP中加入氟化物再植入大鼠皮下，通过比较植入物在不同植入时间的组织学变化，碱性磷酸酶、酸性磷酸酶活性及钙含量来反映BMP的生物活性。

In last few years, it is Protean that ambry can say, glow, and again good design also needs to be behaved through the product, what have standards of product craft, technology and level only is ceaseless and perfect, ability is offerred to consumer quite more the ambry of actor character, high quality ambry can become consumer to seek the target that hold in both hands.

近几年来，橱柜可以说是千变万化、色彩斑斓，而再好的设计也需要通过产品来表现，只有产品工艺、技术规格和标准的不断完善，才能够向消费者提供更优品质的橱柜，高品质的橱柜会成为消费者追捧的对象。

Although he left his native Tyrol after adopting Anabaptism, and while he was forced further to move several times because of his Anabaptist views, Marpeck's skills as a civil engineer enabled him to live in relative security.

虽然他离开本土后，蒂罗尔州通过Anabaptism ，虽然他被迫进一步推动几次，因为他再洗礼派的观点， Marpeck的技能作为一个土木工程师，使他生活在相对安全的。

The results show that A-type granites in eastern China are of diverse crustal origins. They were either derived from anatexis of old lower crust or resulted from partial melting of recycling juvenile altered oceanic crust, and the latter has net contribution to the continental growth.

结果表明，中国东部A型花岗岩物质来源具有多样性，既可起源于古老下地壳深熔作用，也可由再循环年青蚀变洋壳通过部分熔融产生，后者是大陆生长的重要方式之一。

Aiming at the signal processing problems that exist in online fault diagnosis for train running gear, based on discussing the principle of characteristic spectrum analysis, a method of full period and uniform angle sampling is applied, which transfers the vibration signal from time domain into angular domain. The angular domain signal is transferred into corresponding characteristic spectrum using FFT. Through spectrum estimation and analysis, fault characteristic spectrum values of running gear components are acquired to distinguish their faults.

在讨论特征分析方法原理的基础上，针对机车走行部故障在线监测过程中存在的信号分析与处理问题，运用整周期等角度采样方法将时域振动信号转换为角域信号，采用FFT变换将角域信号变换为对应的特征频谱，通过谱估计、谱图分析得到机车走行部各零部件的故障特征谱值，再根据该特征谱值识别机车走行部各零部件的故障。

ObjectiveSevere traumatic patients always had a severe blood loss, for maintaining blood supply of heart and head, the gut would appear ischemic and anoxemia through the mechanisms of intestinal ischemic, reperfusion and release of mediators of inflammation and so on, which could cause functional impairment of intestinal barrier and translocation of intestinal bacterium and endotoxin, accordingly, induce the occur of SIRS (systemic inflammatory response syndrome), sepsis and MODS (multiple organ dysfunction syndrome).

目的严重创伤常伴严重失血，机体为维持心、脑的血供，肠道首先出现缺血缺氧，通过肠道缺血、再灌注、炎症介质的释放等机制，引起肠道屏障功能障碍，肠内细菌及内毒素移位，从而导致SIRS、脓毒症和MODS的发生。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
