中文拼音 [bàozháyāliè]
爆炸壓裂
英文
explosive fracturing-
This paper aims at the characteristics of thermal response of lpg vesse1 under high temperatue, conjoining the project of " study on transportation safety early - wdring system of lpg dangerous goods " supported by transportation departinen of china and the project of " mechanism study and numerical simulation of the explosion of lpg vessel " supported by science foundation of hubei province. the interdisciplinary research has been done among temperature field distribution of lpg vessel under flame surroundings, intensity calculation, crack propagation predication and mechanism of explosive accident, etc. three parts are analyzed and discussed
本文針對高溫環境下液化氣壓力容器的熱響應特性問題，結合交通部重點科技項目「液化氣體類危險品運輸安全預警系統的研究」和湖北省自然科學基金項目「液化氣容器爆炸機理研究及數值模擬」 ，對在火焰包圍下的液化氣壓力容器的溫度場分佈、強度計算、裂紋擴展預測以及爆炸事故機理等方面開展了多學科的交叉研究。It is not, however, the source of a modern bomb ' s main explosive power, for just as the chemical explosives trigger a fission explosion by compressing the plutonium, that fission explosion is used to ignite the third stage, a still - larger fusion explosion, by compressing and heating the main part of the bomb
然而，該連鎖反應並不是核彈主要爆炸能的源頭，因為它只是化學爆炸物通過壓縮鈈而引發分裂性爆炸，並將進一布引發核彈爆炸的第三個階段，即通過壓縮並加熱核彈主體部位而引起的一種更大范圍的分裂性爆炸。In this thesis, a 2 - d axial symmetric n - s equation was solved by using steger - warming flux splitting, muscl, b - l model and finite volume method to simulate an experiment, which was to observe explosion phenomenon
本文用steger - warming分裂和b - l湍流模型的有限體積演算法求解二維軸對稱navier - stokes方程，數值模擬了錐形激波管中爆炸波運動和爆炸波正壓和負壓脈沖。Abstract : in this paper, the characteristic of fracture development under gas explosion action is summerized, which is similar to the fracture development of structure under uniform distributed load. based on previous research, relative software is developed to simulate the dynamic procedure of fracture development. the fractal interpolation method is adopted and saves large amount of storage
文摘:燃氣爆炸災害下房屋裂縫開展的模式與受均布壓力破壞時的相同，在參照實驗所得混凝土裂縫的分形維數資料的基礎上編制了相應的軟體，利用分形插值的方法實現裂縫開展過程的模擬，模擬結果較好地反映了裂縫發展的真實情況，且較以往的模擬方法節約了大量存儲空間The quasi - static damage stage under the quasi - static stress field produced by gas from explosion. finally, the general model for blasting damage and fracture is gained. in the thesis, a gas - driven fracture propagation and damage localization at the crack tip model during explosion products are proposed
根據爆炸力學，將巖石的爆破損傷分為兩個階段來研究，第一階段為爆炸應力波作用下的動態損傷階段，第二階段為爆生氣體靜態壓力場作用下的損傷階段，最終得出了巖石在爆破作用下的爆破損傷斷裂全過程演化模型。分享友人
