原因明显的

Objective:By histochemical method, the four biotinylated lectins (DBA, SBA, WGA, UEA 1) were used to study changos in glycoconjugate expression on the surface of endometrium of 28 cases of RSA without obvious reasons in secretary phase, at the same time, endometrial biopsies were taken for histomorphologic evolution.

本文通过生物素分别标记的双花藕豆凝集素、大豆凝集素、麦胚凝集素及荆豆凝集素（UEA－1）与子宫内膜的反应，应用S－P法研究28例无明显原因反复流产的分泌期子宫内膜糖复合物的变化及与其组织形态学分期的相关性。

In the recent 20 years, the morbility of esophageal adenocarcinoma raised markedly in western countries. The reason of these histological changes was correlated with the increasing incidence of gastroesophageal reflux and esophageal Barrett metaplasia which was caused by the former.

近 20年来，西方国家食管腺癌的发病率明显上升，这种组织学变化的原因，可能与其患胃食管反流的发生率升高，以及由之产生的食管的 Barrett 化生有关。

Increased the production lines automation level, and improve the environment with work term, pushed the business enterprise technique the advance, and this is the reason why have the shaftless driving spread to move the technique on the printing machine quick universal with applied, and this is also this text foundation theories that study that

提高了生产过程的自动化水平，改善了环境和工作条件，推动了企业技术进步，这就是无轴传动技术在印刷机械上迅速普及和应用的原因，这也是本文研究的目的，其意义还在于无轴传动技术的基础理论明显落后于工业应用，具有的优势还远远没有在工业应用中发挥出来，需要进一步研究和创新。

The presence of BaO affected the TPR performance of Co/SiO2, and Ba loading of 2% increased the reduction degree of Co/SiO2 at the moderate temperature (450℃). The difference of the TPR performance between unpromoted and promoted catalyst samples could be ascribed to the induction of the reduction of BaO, and the interactions between barium oxide and silica, barium oxide and cobalt oxide.

研究结果表明，氧化钡明显地影响Co/SiO2的还原性能；添加2%氧化钡提高了Co/SiO2在中温(450℃)条件下的还原度；氧化钡的还原对Co/SiO2还原的诱导、氧化钡与氧化硅及与氧化钴之间的相互作用是导致Co/SiO2还原性能变化的原因。

The frequency value in S phase is 4. 83 times of M phase, 2. 9 times of G1 phase, and 3. 41 times of unsynchronized cells. These results suggested that gene correction events were highly related to S phase. Then we compared the targeting efficacy for two groups of cells in S phase. One group was contact with thymidine and the other one went smoothly through S phase without replication blockage.

基于这种原因，我们对基因定点修复事件做了细胞周期定位分析，发现同步于S期的细胞群发生定点修复的效率明显高于其它各期以及非同步化的细胞，流式细胞仪检测S期定点修复效率为M期细胞的4.83倍，为G1期细胞的2.9倍，是未同步化细胞的3.41倍。

Through the analysis of the conditions and therapeutic effects of 60 cases of the disease, we considered that urethral retention- catheterization and ureteric reflux are the main causes for urinary tract infection,and defense hypofunction of the host is a condition causing the infection.

通过对60例截瘫患者尿路感染病情及疗效分析，我们认为：保留导尿、输尿管返流是诱发尿路感染的最主要原因，宿主的防御功能低下是构成尿路感染的条件；在病程的不同阶段尿路感染各有特点；减少这一并发症的关键在于预防；采用中西医结合疗法能明显提高疗效。

The investigation found that the public have a prime concern over the cause of the water pollution, that public awareness is superficial; the pubic have dependence on government in environmental action but the enthusiasm of public participation was low; environment information channel was simple and hasn't been utilized; and finally the amount WTP of Daps town in 2003 is 0.55～0.98 million Yuan.

结果表明：①居民对水环境污染的原因有了初步的认识，但与实际有明显偏差；②浅层次的局部的&日常生活环保型&环境意识依然存在；③居民在环保行为上为&政府依赖型&，整体参与环保意识不强；④居民获取环保信息渠道单一，政府对主要的信息发布渠道重视不足；⑤2003年该镇居民总支付意愿为55.3～98.2万元。

Sadly, the latest test of a microbicide has shown no protective effect—a result more bitterly disappointing because it followed the apparently positive outcome of a smaller trial of the same substance.

令人沮丧的是，最新的实验显示杀微生物剂并没有保护作用，这一结果更加令人失望的原因是之前同样物质的较小型实验明显产生了积极的结果。

Some of it is just physical -some people have harder skin, and they squeak more-, but I think that a lot of the squeaks are perhaps just bad habits.

这个问题与每个人的身体有一定关系，有的人的皮肤比较硬，于是产生的换把杂音也会比较明显，但是我认为，产生换把杂音的主要原因还是不良的演奏习惯。

Ultimatums, bringing up past pain and unresolved issues, jealousy, or unusual neediness or possessiveness may all be part of the scenario, and what makes all of this quite stressful is that most of it is not blatant but subtle and insidious.

最后通牒：提起过去的伤痛与未解决的问题，嫉妒，不同寻常的穷困与占有欲都有可能成为这次的剧情。这些因素会造成关系紧张的原因是他们并不明显反而微妙且阴险。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
