不变化

The numerical results were in good agreement with the measured results. The experimental and numerical results show that the vortex ring was induced by baroclinic effect and Helmholtz instability in the vicinity of the thruster exit after the donation wave exhausted the tube. The intensity, shape and location of the suspended shock varied when the shape of the vortex ring changed.

爆轰波溢出爆轰管后，斜压效应和Helmholtz不稳定导致涡环的产生，同时在流场中形成止于涡环的悬吊激波，涡环形状的变化又引起悬吊激波的强度、形状和位置的变化。

For a constant impedance load or a constant current load, if regulating the secondary voltage by making the changer ratio higher, the primary voltage will get much lower while the load power is restoring, and the power will then lose balance. For a constant power load or a motor load, since the change of OLTC has no or little influence on the load power, the voltage of primary side almost has no change whether the tap operates or not. The influence on the voltage stability with respect to the dynamic restoring load which is sensitive to voltage is also discussed.

对于恒阻抗和恒电流型负荷，在变比上调恢复副边电压的情况下，负荷功率恢复，又使原边电压下降，可使系统功率失去平衡，而对于恒功率负荷和电动机负荷，OLTC的变化不会引起负荷功率的恢复，OLTC的变化对系统电压稳定有利；同时研究了对于一般电压敏感和具有动态恢复特性的负荷，反调分接头对电压稳定性的影响。

The C31 and C33 of the myopia subjects with moderate astigmatism show statistically significant changes after being fitted with both sphere and moderate cylinder trial lenses.

单纯近视者矫正离焦后引起C40的明显变化；近视中度散光者完全矫正屈光不正后呈现C31和C33的显著变化。

At the same time to meet changes in planning, land use did not change; by the planning department's approval of the construction area of change is better than the original planning area of less than 20%; transferee a fresh increase in sexual intercourse to price and other conditions, the City Center land use can be directly collection of new construction area and price, fill out the "transfer contract changes that table", the directly to the relevant departments issued new land price to pay to prove the case.

与此同时，以满足变化的规划，土地利用没有改变；由规划部门批准的建筑面积的变化是优于原来的规划面积不少于20 ％；受让人新增加性交价格和其他条件，城市中心土地利用可直接收集新的建筑面积和价格，填写&转让合同变更表&的项目，直接向有关部门发布了新的土地的代价来证明的情况。

Objective: To observe the change of regional cerebral blood flow in different region of interest under quiet condition and performing hand motor condition with single photon emission tomography, elucidate the mechanism of the brain regions activated by simple hand motor (repetitive and sequential finger- to- thumb opposition movements in turn) and detect the role of active cortical areas by analyzing the difference of rCBF in different age groups.

目的：本研究的目的是运用单光子发射断层扫描仪对比观察正常人在安静状态下和执行手指简单运动状态下脑内不同感兴趣区（region of interest， ROI）的血流量变化情况，进而阐明简单运动模式下脑内运动相关功能区的激发情况，并通过分析不同年龄组运动区激发时血流量变化的差异来探讨运动功能区的作用，对于临床中枢神经系统瘫痪后的运动功能重建和康复训练具有指导意义。

It is found that the position of vortex shedding is different fro m three-row cylinders. The time-mean pressure coefficient along the surfaces o f the cylinders is not changed with the void friction. But the fluctuating press ure coefficient reduces with the increase of void fraction.

试验结果表明：沿圆柱表面周向的旋涡分离点随着流动向深层发展，并向圆柱的背部移动；圆柱表面沿周向的时均压力系数几乎不随含气率的变化而变化；圆柱表面的脉动压力系数随着含气率的增加而减小。

The light surface fire and low intensity surface fire classified by fire intensity have no significant effect on the changing extension of these properties.

上述所有化学性质的变化与林火强度都不存在线性相关关系，以林火强度为依据划分的轻度地表火和低度地表火对土壤各化学性质变化程度没有影响。

A side small leaf shape has the entire reason, the circle obtuse, incisive, the stern wave standard, the edge whirls around the male trunk and branches, the dragon tune do not be vigorous.

雄蕊相应减少或稍有瓣化，雌蕊正常；在演进过程中同样有雌蕊瓣化现象，有的子房不变，仅柱头稍有变化；有的子房和柱头均发生变化，变成花瓣形状。

雄蕊相应减少或稍有瓣化，雌蕊正常；在演进过程中同样有雌蕊瓣化现象，有的子房不变，仅柱头稍有变化；有的子房和柱头均发生变化，变成花瓣形状。

After the change is done by technical power, the gallery may not be necessarily on-site and the artistic collection may not be necessarily materialized. They are probably virtual reality. The world is stepping up its pace; modernity and the modern time concept have been changed. The technical power renders human relations rather subtle, so does the relation between human and art.

未来艺术的概念与我们现在的认知还会有很大变化，技术推动材料变化之后，有可能美术馆不再是现场的了，艺术品的收藏也不一定是物质上的，它有可能就是虚拟现实的。

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。
