脉动的

When after the war of 1870 national feeling was pulsating very strongly in the veins of reunited Germany, the German cynologists were on the lookout for a national dog, and for that purpose the Great Dane was re-christened "Deutsche Dogge," and elected as the champion of German Dogdom.

It appears that the relationships between the land surface heat fluxes and the heterogeneous length scale are significant, but the mesoscale heat fluxes don't indicate similar relationships with heterogeneous length scale. The representability of gridcell averaged surface fluxes is good but that of mesoscale fluxes is not so good.

这些结果表明地表水、热通量的空间分布尺度与非均匀尺度之间存在较好的对应关系，而中尺度水、热通量与非均匀尺度的关系并不明显，说明地表水、热通量的网格平均值的代表性较好，但是不能反映次网格脉动的影响，而中尺度通量的网格平均值的代表性较差。

Both overlong or overshort bottom duration and overlong or overshort fluctuation period are unfavorable for reduction of non-diamond content. Only moderate ones have optimal effects on it.3 Compared with a smooth microwave, a fluctuating one can reduce the diamond nucleation density slightly.4 In fluctuating microwave, even if a higher CH〓 concentration chosen, diamond films with quality better than that of those deposited at a lower CH〓 concentration and in smooth microwave can be obtained.In smooth microwave, the influence of O〓 upon the diamond films＇MWPCVD was investigated. It is found that:1 In the range of lower O〓 concentration, its increase is beneficial to improvement of quality of diamond films, but in that of higher one, its increase conversely deteriorates the quality of diamond films.

Periodic fluid pulsation in aeroplane hydraulic piping could induce fluid-construction vibration and lead to fatigue damage. It is impossible to find the error sensor's optimization location because of the pressure standing wave, and the pulsation attenuation effect is not perfect when adopting pulsation attenuation at single point. For this reason, a distributed active control method of fluid pulsation was presented. To avoid stationary point in all aviation states, several fluid pulsation actuators and error pressure sensors were placed along the piping. The second fluid pulsation produced by actuators can counteract the primary pulsation brought by aviation piston pump and make the mean pulsation of whole piping minimum when adopting adaptive feed- forward control and the filtered-X least mean square algorithm.
