再发生

Results: 40 patients were one-time success, dysphagia improve the rate of 100 per cent, of which 11 cases a sternum pain, nausea and vomiting in four cases, one case of a restenosis.

结果：40例患者均一次性成功，吞咽困难改善率达100%，其中11例出现胸骨后疼痛，4例发生恶心呕吐，1例出现再狭窄。

The experimental results indicated that the light-induced MR molecular reorientation effect, the so-called twisted angle, caused by the adsorbed MR, decreased with increasing ellipticity of the elliptically polarized green light. Notably, zero pre-tilt angle of LC alignment was achieved in this experiment.

再利用不同光强度的圆偏振绿光雷射激发MR，观察并探讨MR吸附的结果，实验结果显示在圆偏振光各方向能量均等的情况之下，不会有扭转角跟倾角产生，且在吸附面上有不均匀的成核现象发生。

It was comfirmed by CT or MRI among 32 cases. Conclusions Under normal intracranial pressure, if the dura mater is repaired properly at the skull-base defect and reinforced by a pedicled pericranial flap,an encephalomeningocele can be prevented.It is not necessary to take free bone graft when the size of cranial base bone defect is smaller than or equal to 4cm .

手术中只要将颅底正常硬脑膜修补完整，或选用力学性能接近甚至超过正常硬脑膜的材料进行修补，再辅以带蒂颅骨膜瓣等方法加强颅底重建后，术后颅内压不高，在通常的颅底缺损范围内(缺损直径不超过4cm)，一般不会发生脑膜脑疝出，不必行颅底骨移植。

However, this technique continues to be characterized by its propensity to elicit passive results, such as restenosis, inflammation, thrombopoiesis, formation of encrustation or stone.

但是，再狭窄、染、血、壳或者结石的形成仍然是支架植入术后容易发生的问题。

What happens if you read after the end of the file?

如果已经到了文件末尾，我再从文件中读数据会有什么事情发生呢？

Another set of thermal equilibrium diagram of the steam turbine's regenerative system to the supplier.

3.3需方向供方提供汽轮机回热系统热平衡图一套，具体见技术规范书附件，如上述工况发生供方认可的变化，需方再另行提供一套汽机回热系统热平衡图。

U.S., French and South Korean experts estimated that the power of the explosion, about 240 miles northeast of Pyongyang, was equivalent to about 500 metric tons of TNT, which a senior U.S. intelligence community official said was unusually small for a nuclear blast.

美 法 韩的军事专家正在对这次的爆炸为例做出评估，他们认为这次发生在平壤东北部240英里处的爆炸威力仅为500吨TNT炸弹的威力，美国情报部门一位高级官员称这是再小不过的一次核爆了！

Methods The propylbridged biferrocenyl substituted pyridazinone was synthesized by the reaction of propylbridged biferrocene with ethyl succinyl chloride, and then condensed with hydrazine hydrate.

双二茂铁丙烷先与丁二酸单乙酯酰氯发生酰化反应，生成的1，4酮酸酯再与水合肼缩合得到含有双二茂铁丙烷的哒嗪酮衍生物。

After esterification, the ethyl-2-chloro-3-phenylpropionate reacts with diethyl malonate under the catalysis of sodium ethylate, and we obtain the corresponding triethyl ester. The-benzylsuccinic acid is formed by the triethyl ester reacting with concentrate hydrochloric acid and taking place hydrolyzation and decarboxylation reaction at the same time. In order to avoid the formation of cinnamic acid, the sodium ethylate and diethyl malonate must be react sufficiently. The course has simple operation, inexpensive materials and better yield.

具体制备工艺为：首先以L-苯丙氨酸为原料采用重氮化方法得到-2-氯-3-苯基丙酸，再经酯化得到-2-氯-3-苯基丙酸乙酯后在乙醇钠催化作用下和丙二酸二乙酯缩合，发生SN2反应，得到相应的三乙酯，然后经水解和脱羧，得到-苄基丁二酸；在实验中乙醇钠要和丙二酸二乙酯充分反应，避免生成肉桂酸乙酯；该过程操作简单，原料便宜，产率较高，总收率可达到26.8%。

We put forward some new ideas, such as: About the kernel word "tree", Whether "Mu" has the tendency to refer to the tall trees in terms of "Shu" and "Mu"; About the word "sun", we analyze the reason why "Taiyang" has been used until now, but "Daming" which has the same way of construction with "Taiyang" has disappeared for a long time;About the kernel word "swim", we think that "You" is not the same with "Youyong", and takes"swim" as an obvious kernel word which has dual characters in historic and etymologic significance; About the kernel word "sit", though refers to a posture that differes in ancient time and modern days, did not change the meaning of itself, but changes in semantic field.

4提出了一些我们新的想法，如关于"树"、"木"之间，"木"是否有指高大的树的倾向；在核心词"日"中，分析了"大明"、"太阳"构词方式一样，而"太阳"却一直沿用至今的原因；对核心词"游"的再认识，认为"游"是汉语核心词有着社会历史和语源上的双重证据；在核心词"坐"中，古今坐姿的变化，并未使"坐"本身的词义发生演变，而是导致了"坐"语义场的变化等。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
