Ligusticum has great diversification in northwestern Yunnan of China, so this region is probably the most diversified center for it.

在滇西北地区，藁本属不仅植物种类丰富，而且集中了叶柄解剖的全部类型，形态分化十分活跃，在核形态上也表现出一些变异，可能是这个属的最大变异中心。

La consideration of the heat market in northern cities, the economics of the pool梩ype low temperature heating reactor and the investment of urban heating system, the scale of protype reactor is chosen 200 MW, which will be able to meet the requirement of cities with more than 500 thousands population, and about 2/3 urban heat market can be met.

考虑到国内北京城市集中供热的需求情况及池式低温供热堆的技术经济特性，预计选用200MW作为单堆容量较为合适。它可以满足50万人口以上大城市供热的需要，约占城市总人口数量的2/3以上的需要。在某些地区，选建100MW池式供热难在经济上也是有利的。

It is testified if the time reversed seismogram were used as the loading curve and an efficient source of force were exerted on the rock at the seismographic station,then artificial input energy will focus on the hypocenter and cause an intense impact,therefore an earthquake would be touched off.

模拟结果表明，如果将地震图进行时间逆转后，作为加载曲线，在地震台站点上通过一个有效的力源加载于基岩，利用时间逆转效应，可以将人工施加的能量在某一瞬间集中到以往的震源，引起一个强烈的冲击，因而可能触发地震。

The third chapter is that the author makes use of the rhetoric basic theory to analyse Li Bai's poems. In this chapter the author summerize the main rhetorical characteristics of his poems on the basis of the former describings and point out the shortcomings and dissufficiences of the ancient people.

第三章是笔者利用修辞学的基本理论来集中分析李白诗歌的文本，在借鉴前代人成果的基础上总结出李白诗歌的主要修辞特色，并指出前人在描述李白诗歌的修辞艺术特色方面的局限和不足。

Results indicate that radial distance of the bushing from the rotor center and the radius of the hemispherical bushing significantly affect wear rate,and minimzing both two values will result in lowest wear for micro-rotor systems in MEMS.However,it is noted that the bearing radius sets a lower limit on the hemispherical bushing radius since the bushings are located beyond the rotor inner radius.It is desirable to reduce their effects on friction and wear on micro-rotors by regulating the radius of the bushing and the radial distance of the bushing from the rotor center within permissive range of micro-fabrication.Severe wear exists with increasing applied load and rotating speed of the rotor.Stress distributions in the contact region are different from Hertz solutions due to the convergence stresses apearing on the uncontinuous curvature line and the contact pressures display symmetrical parabola in the contact region.

结果表明：在MEMS微转子系统中，微转子轴衬偏心距离和转子轴衬半径影响线磨损率，以两者减至最小为较理想，但须注意设计中轴承半径的限制，并使轴衬偏心距离大于轴承内半径；在转子加工制造许可的范围内，可以通过调整转子轴衬的半径和偏心距离来减少摩擦磨损对微电机的影响，随着转子所承受载荷和转子旋转速度的增加，其磨损严重；接触区的应力分布不同于经典Hertz解，这是由于应力集中出现在不连续的曲率线上，且接触区的接触压力呈现轴对称抛物线状分布。

The reason that why bubbles grew and how the gas was released from undecomposed TiH_2 were stated. The merging of bubbles and formation of bubble-free laye...

结果表明：未分解的TiH2颗粒粘附在熔体内形成的较小气泡表面，即气/液相界面上；在恒温发泡过程中气泡壁上吸附的尚未分解的TiH2颗粒进一步分解并向气泡内释放气体，使气泡长大；相邻气泡壁上的TiH2局部浓度较高并集中释放气体，导致气泡壁破裂及气泡间的合并。

The application of conventional screws after locking screws have been inserted can serve to increase and localise forces through the area of plate or bone where they are inserted and may lead to failure of the construct.

在锁定螺钉置入之后再应用传统螺钉可能会使作用在钢板上或放置钢板除的骨的应力增加和集中，最终可能导致钢板断裂。

To improve your skill at reading nonverbal cues, focus on one type of behavior at a time.

为了改善在阅读上的行为，请在一次非语言线索，集中你的技能。

Chapter 8 puts forward that the establishment of corporate equity ownership structure must adapt to its outer business circumstance after theory study, comparative analysis and positive analysis. Furthermore, it disserts that modest concentrated and rights restricted equity ownership structure mode in China, as well as it puts forward the policy suggestion on improving equity ownership structure.

第八章，在理论研究、比较分析与实证分析的基础上，提出股权结构的设置必须适应公司的外部经营环境；在现阶段应根据我国国情和现实建立适度集中而权利制衡的股权结构模式，以及改善股权结构的政策建议。

When there's a lot of stuff going on around you when you need to concentrate on a creative task, it mucks around for something to interrupt your concentration, and as soon as it's found something, all that has gone wrong in your life seems to run like a film before your eyes.

当你需要集中精神在一件创造性的任务上时，却有很多杂念围绕着你，它会干扰你的专注，一旦看见某样事物，你生活中的事情就会像电影在你眼前闪过。
