Because that the middle and upper atmosphere is a complex system of coupling between the dynamics, photochemistry and radiation, in this project, we mainl study the effects of the interaction between the dynamics, photochemistry and radiation on gravity waves propagation in the mesosphere and low thermosphere by using a photochemical-dynamical gravity wave model.

由于中高层大气是光化、辐射和动力相互作用的复杂系统，本项目集中探讨了光化和辐射所造成的非绝热过程对中高层和低热层大气重力波的影响，着重对中层顶区大气重力波不稳定机制以及光化-动力学耦合过程进行研究，并把计算结果与观测进行比较。

Such so-called Dyson spheres would, if they exist, reradiate captured energy (after some of it had been put to good use) as heat—infra-red radiation.

这样的中空球结构称为&Dyson球&。如果这样的外星生物存在，他们捕捉的能量在利用之后可能有再辐射，即热红外辐射。

Normally, it is impossible to distinguish Cherenkov radiation generated by positrons from that created by electrons.

一般来说，由电子引发的切伦科夫辐射和由正电子引发的切伦科夫辐射是不可能区分开的。

The results showed that the red /blue color index during twilight changed evidently with AODs in lower atmosphere. When AOD was small, there was a maximum of the radiance at 450nm in the high view elevation angle. So the sky color at the zenith is blue. However, the maximum shifted to red wavelength (about 700nm) with the fall of view elevation angle.

计算结果分析表明，曙暮光时天空辐射强度的红蓝光颜色指数随近地层大气气溶胶光学厚度的变化显著；当τ较小时，太阳辐射随波长的变化显著，在高仰角450nm附近有极大值，天顶方向以蓝色调为主；而在低仰角极大值向红光方向移动。

According to RS model, radio radiation come from the coherent curvature radiation, and the coherent mechanism is the two-stream instability produced by that primary particles move through the second generation particle plasma.

根据RS模型，射电辐射来自于第二代粒子的相干曲率辐射，而相干机制则是原初粒子穿过第二代粒子组成的等离子体时形成的双流不稳定性。

Our result has demonstrated that synchrotron X-rays have similar damage effects to SAMs with –CH3 or O=C-OH tail group, and S-Ag bond is much resistant to X-ray induced damage than S-Au bond.

因此，以比较硫-金属键结强度的方法来做为受到同步辐射X光破坏程度的指标，本研究显示：同步辐射X光对-CH3及O=C-OH尾端官能基之硫醇分子的破坏作用相近，且S-Ag键结抵抗X光破坏能力比S-Au为强。

To study the wet thermal protective performance of fabric for fire fighters wears, 4 kinds of fire-retardant multilayer fabric suitable for fire fighters wears were used as samples, and the thermal protective performance value of the sample fabrics were tested through thermal radiation and thermal convection integrated experiment under 5 kinds of wet state and required time leading to the second-degree burn. Different layer fabrics' thermal protective performance after absorbing water was compared.
