At present, several methods such as TNT equivalence method, TNO method, British gas VCE method, Shell method and Multi-energy method are used to evaluate the above parameters, in which the multi-energy method is considered as a much more advanced model for vapor cloud explosion prediction.
以多能法中距离 -超压关系图为例 ,介绍了一种运用前馈多层感知器网络对现行多能法中查图步骤进行改进的方法。
On the basis of analyzing the hazardous characteristic and the characteristic of vapor cloud explosion accident of liquefied petroleum gas,two methods TNT equivalent method and TNO multi-energy method are used to calculate the consequence of vapor cloud explosion accident in LPG storage tank,the radius of death,sev.
本文在分析液化石油气的危险特性和发生蒸气云爆炸事故特点的基础上,用两种常用的蒸气云爆炸后果模拟方法TNT当量法和TNO多能法对液化石油气储罐发生蒸气云爆炸的后果进行计算,分别得到死亡、重伤、轻伤和财产损失半径。

Oct-4 and Nanog are two critical transcriptional factors to keep pluripotency and self-renewal of stem cells in vivo and in vitro, and they usually express only in pluripotent cells and not in differentiated cells.
Oct-4和Nanog是两种维持干细胞多能性和自我更新的转录因子,它们通过结合靶基因调控区,选择性地抑制分化基因表达或促进多能性基因表达。
This study did microinjection to Kunming white mouse inbred embryos to test its in vitro developmental ability, then pluripotency of porcine EG cells was tested with production of chimera by blastocyst injection.
本研究首先利用近交系昆明白小鼠进行胚胎显微注射观察发育效果，然后利用所获五指山猪EG细胞制作嵌合体检验EG细胞多能性，最终获得国内首例胚胎干细胞(EG细胞)嵌合体猪，经DNA分析确认在多种组织中存在嵌合状态。
