High-order harmonic radiation with noble gas and N〓 in static gas target has been obtained, and the effects on high-order harmonic efficiencies due to laser intensities , polarization, gas densities, confocal parameter, media characteristic and phase mismatch have been discussed. The experimental results show that the high-order intensities grow with the incident laser intensities and gas densities, and high-order harmonic signals amplify in the same time.

高次谐波辐射是强场物理中与电离过程相伴而生另一种重要过程，本文利用飞秒激光在静态气室中获得全部的稀有气体原子以及氮双原子分子5到21次的谐波发射，着重讨论了激光功率密度、激光偏振、气体密度、共焦参数、介质本身以及相位失配对高次谐波转换效率的影响。

Owing to pump, when the liquid flow out of the impeller, its speed energy and stress energy both develop much, the liquid debarred by the impeller , most speed energy is transferred to stress energy ,and then it is transported through pipeline .At this moment ,the entry of the impeller become vacuum or low-pressure , hydraulic pressure effect on the liquid in the absorbing pool, and the liquid is pulled into the entry of the impeller , so ,the rotating impeller continuous inhalants and Drainage liquid.

由于泵的作用液体从叶轮进口流向出口的过程中，其速度能和压力能都得到增加，被叶轮排出的液体经过压出室，大部分速度能转换成压力能，然后沿排出管路输送出去，这时，叶轮进口处因液体的排出而形成真空或低压，吸水池中的液体在液面压力的作用下，被压入叶轮的进口，于是，旋转着的叶轮就连续不断地吸入和排出液体。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
