为粒子属性引入浓度函数和作用半径,从而只需少量粒子就可快速获得浓度场分布。
The density function and working radium are added to the particle properties, thus very little particles are needed to generate the smoke density field.
这不仅催促的去为找到这个粒子开展互相竞赛,而且也催促人们去建立其背后想法的所有者身份。
This gave new urgency not only to the race to find the particle, but also to establishing authorship of the ideas behind it.
确定应该将模式粒子定义为具有局部作用域还是全局作用域并不总是那么容易。
It's not always easy to determine whether you should define schema particles with local or global scope.
And, being he described as an infinity of indivisible particles, which he dubbed atoms from the Greek.
他将原子描述为无限的极微小的,粒子,他用德语给原子命名。
And it turns out the second solution, with negative energy, was when the theory is telling you, hey, there are particles and there are anti-particles, and the negative energy when properly interpreted will describe anti-particles.
结果,后来证明,第二个根,也就是能量为负的那个根,正是理论的关键,世界上既有粒子,也有反粒子,负能量就是用来解释反粒子的
It's a particle of mass m and momentum p has this energy so you solve for the energy, you get two answers.
一个质量为m,动量为p的粒子,有这么大的能量,你解出能量,得到两个解
