expanding shell 中文意思是什麼
-
They are expanding model of the bomb body, bursting model of the bomb body and motion model of the fragments. according to the models, the paper gives a detailed algorithm for the whole process of the bomb explosion. ( 7 ) based on the explosion mechanism and the stochastic characteristic of the shell, the paper advances some reasonable hypotheses and supposes that the explosion process of the shell is a markov process, thus constitutes two explosion models of the shell : the imitation model an
（刀從爆炸的機理出發，利用合理的假設，將殼體的爆炸過程處理為馬爾可夫過程，把爆炸的機理同爆炸的隨機性聯系在一起，建立了殼體爆炸的兩種模型:模擬模型和簡化模型，提出了破裂程度的倍密度函數和破裂方向的倍密度函數兩個概念，得到了基於半邊結構的虛擬殼體爆炸過程中任一條邊出現裂縫的概率公式。 -
To specify the project, by selecting materials, choosing construction methods, arranging construction process, locating expanding joints, disposing key construction, the outside shell temperature was controlled not exceeding + 25 at surroundings, which met the need of design and check requirement
