其中稀薄氣體對流熱、輻射熱和核沉積熱是熱負荷的重要組成部分。We found the " forward stimulated raman scattering " will be excited if the pulse length is greater than plasma wave length. the " forward stimulation raman scattering " decreases the phase velocity and the amplitude of the wake wave which will lead to the reduction of maximum kinetic energy of the electrons trapped
結論是:當脈沖長度接近等離子體波長時,稀薄等離子體將發生「前向受激raman散射」 ,它使脈沖后沿拉長,導致尾流場的相速度變小,以至於被尾流場「捕獲」的電子最大動能大大下降。In the previous direct simulation monte carlo ( dsmc ) method used in the dilute gas - solid flow, particle collision probability was calculated by the equation used for rarefied gas molecules. and gas phase was simulated by the laminar navier - stokes equations

在綜合考慮了稀薄氣體動力學問題各種解法和本課題實際研究的基礎上,本文採用直接模擬蒙特卡羅方法( dsmc )對微噴管內流場進行建模和計算,並分析了各種工況下的內流場變化。For newtonian fluid, the influence of the plate undulations, the reynolds number and the thickness of the film are shown by parameter studies ; for non - newtonian fluid, the shear - thinning coefficient on the film flow is shown by parameter studies
在薄膜流動過程中,考慮波形板的輪廓形狀參數變化、流動中雷諾數的大小、薄膜厚度的變化以及非牛頓流體的剪切變稀系數對薄膜流動的流變特性影響。There are some defects on the wildlife management & utilization system, for example, in administer system : the trade do some harm for rare species and endangered species, in lawmaking, in executing law. in order to perfect our wildlife management & utilization system, we must improve on ideology. lawmaking, executing and administer system. only this can we come out a road of sustainable utilization and arrive at the well - circulation
那麼我國野生動物經營利用制度到底存在哪些缺陷呢,這體現在管理制度方面:貿易對珍稀、瀕危動物的危害,野生動物利用的技術含量低,野生動物的資金投入不夠以及野生動物及其產品流通領域秩序混亂;立法方面:產權制度、非國家重點保護野生動物的管理、野生動物地方立法等幾個方面的問題;以及執法方面:地方保護主義盛行、執法不嚴、執法力量薄弱的問題。分享友人
