晕

The article corrected the inexactitude conceptions of gravitational shock, swoon by low blood pressure when standing and swoon by blood vessel dilatation.

该文对"重力性休克"、"直立位低血压性晕厥"、"血管扩张性晕厥"这三个欠严谨的概念进行了必要的修正。

Labradorite which is a plagioclase feldspar of the triclinic class is well known for the striking iridescence which it exhibits. What is the material which is responsible for the iridescence of labradorite and why is it present?

上世纪七、八十年代，拉长石的晕彩成因引起了人们的广泛关注，普遍认为拉长石的晕彩色并非因其晶体内部的杂质或包裹体所致，更可能是因拉长石内部的周期性层状结构对光的干涉作用所致。

Which one is responsible for the iridescence is not clearly until now. To understand the origin and distributed characteristics of iridescence in labradorite, microscope, XRD, EPMA, SEM, TEM, STEM and SAED have been taken in the paper.

作者在前人研究的基础上，运用偏光显微镜、电子探针、X射线衍射、扫描电镜、透射电镜等测试手段，对无晕彩拉长石和有晕彩拉长石在成分和结构上进行了详细深入的对比研究。

The results showed that there were two kinds of grains in the cells,one was large and had low electron density,Gl for short,while the other was small and had high electron density,Gh for short.The latter ones had a circle around it which can be seen through the microscope.During the aroma releasing period,the shape of the two grains changed distinctly,which led to the inference that Gl was the leucoplast,the store-room of aroma precursors or energe substances,and that the Gh was probably the lysosome which is related to the enzyme system?s aroma producing.The circle around Gh is the formed fragrant constituents and the aroma forming is the result of the interaction of Gh and Gl .

结果发现，茉莉花瓣细胞中存在电子密度较低、体积较大的颗粒和电子密度较高、体积较小的颗粒（分别简称为Gl和Gh颗粒），并在Gh颗粒周围存在清晰的晕圈；在茉莉花释香过程中，两种颗粒在形态上均发生明显的变化，推测Gl颗粒可能是白色体，是茉莉花香气前体物或能量物质的贮存器，Gh颗粒可能为溶酶体，与香气形成的酶系统有关，Gh颗粒周围存在的晕圈可能是香气物质，香气物质的形成是Gl和Gh颗粒相互作用的结果。

Major cardiac diseases have relatively few symptoms, including pain; dyspnea; weakness and fatigue; palpitations; light-headedness, presyncope, and syncope; and other symptoms that may be due to the cardiac disease or may accompany it.

一些主要的心脏疾病症状相对较少，包括疼痛、呼吸困难、虚弱和乏力、心悸、头晕、晕厥先兆和晕厥；其他一些症状，有的可能是由心脏疾病引起的，有的则是伴随心脏病发生的。

Serious heart disease or arrhythmias that significantly limit cardiac output may cause light-headedness, presyncope, or syncope （a sudden brief loss of consciousness, with loss of postural tone）.

严重限制心排血量的严重心脏病或心律失常可引起头晕，晕厥先兆和晕厥（意识的短暂性突然丧失伴姿势张力丧失）。

We suggest that monitory of the hemodynamic changes in posterior circulation is more relevant than monitory the anterior circulation in the study of syncope.

显示后大脑动脉的血流变化对瞬间的姿势改变远较中大脑动脉的变化显著且有意义，然此结果是否与临床上起立性晕厥病人的晕厥机制有关，仍需进一步的研究。

Results Nice configuration and good function were maintained in all cases. Conclusion The technique of eliminating vertical scar with inferior pedicle nipple-areolar flap in reduction mammaplasty is a reasonable method to obtain nice breast configuration and good function.

结果：21例患者术后双乳对称，下垂状况纠正，体积缩小，乳头乳晕感觉良好，术后瘢痕隐蔽。2例合并副乳，1例合并乳头内陷的患者同时手术切除矫正。2例乳晕表皮营养不良、部分坏死，经换药愈合。

There was a significant association for both selective and nonselective NSAIDs with acute renal failure, but confirmatory studies are required.

选择性和非选择性NSAIDs，两种药物均与急性肾衰竭存在显著相关性，但仍需进行证实研究。晕啊，没了。我晕，没了

Corona discharge characteristics of beam-plate electrode in electrostatic oiler have been studied from the plasma body theory.

依等离子体理论，研究了静电涂油机梁板电极电晕的放电特性，同时计算得到了梁板电极电晕放电的起晕场强和起晕电压，定性的揭示了油液荷电的雾化机理，为静电涂油机的研制改造提供了参考依据。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
