In this paper, a three-dimensional simulation has been performed to investigate the potential consequences of flammable vapor explosion in a tunnel with an obstacle, the obstacle with different area blockage ratios (10, 20, 30 and 40%). The blast wave shape, increase in the maximum explosion ...

in a heat wave直译是“在一波热浪中”，是指处于炎热的天气中，是一种情境或状态，不是指某个具体的日子，所以不能用on。In a hot wave 直接翻译的意思是：在热浪之中，wave是浪花的意思。所以应该是in the wave。不可能是在浪花之上。只有在day的前面用on，而这句话是意译成“大热天”，所以...
An ensemble of atoms can operate as a quantum sensor by placing atoms in a superposition of two different states. Upon measurement of the sensor, each atom is individually projected into one of the two states. Creating quantum correlations between the atoms, that is entangling them, could lead...
你说的最后一句没错，在“某一天”，前面的介词应当用“on”，如“on Sunday”，在周天;“on 29th Apirl”，在4月29日…但这里的“wave”是“浪，波浪”之意，“in a heat wave”意为“在热浪之中”，当然要用“in”了。in

Head-on collision and overtaking collision between a KdV solitary wave and an envelope solitary wave are first studied in present paper by using Particle-in-cell (PIC) method in a dusty plasma. There are phase shifts of the KdV solitary wave in both head-on collision and the overtaking colli...
