隧道效应

In 1961 they published the first carrier will be injected into the semiconductor PN junction to achieve the "injection laser" exposition and demonstration in the tunnel diodes as high as in Jane and the PN junction to achieve population inversion (which is Produced by stimulated emission of the necessary conditions for) the possibility, but also that active high-density areas around the most active carrier of the border areas on both sides of the refractive index of a difference, creating optical waveguide effect.

他们又于1961年最先公开发表将载流子注入半导体PN结以实现"注入激光器"的论述，并论证了在如隧道二极管中那样高度简并的PN结中实现粒子数反转(这是产生受激发射的必要条件)的可能性，而且还认为有源区周围高密度的多数载流子造成有源区边界两边的折射率有一差值，因而产生光波导效应。

The effect of special structural and excavating way to the blasting vibration should be taken into account and be studied.

连拱隧道的特殊结构形式和开挖方式对爆破震动效应有着一定的影响，因此，有必要对连拱隧道情况下的爆破振动效应进行研究。

This thesis is based on the developing project of "Testing and research on the related technology of the aerodynamic effect in the high speed railway tunnel", which is from the national railway department and also based on the project of "The research on the micro-pressure wave and tunnel hood around the gate of the tunnel in YuHuai railway with the speed of 200km/h",which is from the second surveyed and design institute of China Railways. Research on the lucubration of tunnel aerodynamic effects mechanism and corresponding alleviation measure was carried out.

本文以铁道部科技研究开发计划项目《高速铁路隧道空气动力学相关技术的研究与试验测试》和铁道部第二勘测设计院《遂渝铁路时速200公里隧道洞口微压波及缓冲设施研究》为依托，结合我国国情，对隧道空气动力学效应的作用机制和其减缓措施进行研究。

The results showed that the internal force was increased prodigiously due to the earthquake induced liquefaction and the closing phenomenon of tunnel occurred.

研究结果表明，区间隧道在地震液化作用下内力有了很大的提高，而且隧道会产生闭合效应。

On the basis of the present construction situation of Sinitic mountain tunnel method, the new concepts of ahead displacement, releasing displacement in excavating, early displacement and the later displacement, which are the new division from the tunnel excavation displacement three-dimensional effect, have been proposed.

结合山岭隧道新奥法施工现状，首次提出了隧道位移空间效应的"先期位移"、"开挖瞬时释放位移"、"前期位移"和"后期位移"的新概念。

In fact, tunnel fire is unsteady and variational because of throttling effect and buoyancy effect.

实际上，在节流效应和浮力效应作用下，隧道火灾是动态变化的。

Considering the space and time effect of part divided in excavating above the Metro tunnel, the time of soil excavating and the bottom exposed should be less when space effect is inconspicuous, it is good for reducing upheave.

2考虑轨道正上方土体分段开挖的时空综合效应，对土体的开挖应该在保证空间效应变化不大的情况下尽量缩短开挖及坑底暴露时间，有利于减少基坑变形及基坑下方隧道的纵向变形。

This article discussed the application of the research results of photobiological effect and mesopic vision in the tunnel lighting, and the authors considered that the total vision effect of photobiological effect and mesopic vision could be represented by the reaction time.

该文探讨了光生物效应和中间视觉的视觉科学研究成果在隧道照明工程的应用，并认为光生物效应和中间视觉的视觉总效果可以用反应时间来表征。

The root of this is that the controlling profit has been strengthened and the the"tunnel behaviours" have been inspirited to actualize under the current corporate governance system in China.

结果显示，中国上市公司控股股东行为效应指数偏低，其行为具有引发较强负外部效应的倾向，根源在于中国现有的公司治理制度安排强化了控股股东的控制收益，激励其实施隧道行为。

The results indicate that the index of behaviors of controlling shareholders in china is low and their behaviors bring strong negative externality. the root of this is that the controlling profit has been strengthened and the the"tunnel behaviours" have been inspirited to actualize under the current corporate governance system in china.

结果显示，中国上市公司控股股东行为效应指数偏低，其行为具有引发较强负外部效应的倾向，根源在于中国现有的公司治理制度安排强化了控股股东的控制收益，激励其实施隧道行为。
