查询词典 constant angular acceleration

When electron accelerates, its charge quantity won't change, as a result, its electromagnetic mass is constant, and the electromagnetic mass won't satisfy Lorentz transformation,thus, there is obvious inconsonance if we treat electromagnetic mass as a part of the gravity mass ---- as long as we insist the idea that the charge quantity of any electron is a constant.

当电子加速运动的时候，其电量是不会改变，所以其电磁质量不会发生改变，电磁质量不满足Lorentz transformation，因此把电磁质量作为引力质量的一部分存在着不协调性——只要维持电子电荷值不变的观念，这个问题不管怎么也解释不通。

When male mated consecutively in a night, mating interval, duration for mating, each mounting, intromission and the last mount, and copulatory mass kept constant, suggesting that male possess a pattern of constant mating investment, which might result from intense sperm competition in this species.

雄兽连续交配时，交配间隔、交配持续时间、每次爬跨持续时间、总爬跨持续时间、最后一次爬跨持续时间、射精持续时间等行为参数以及交配栓的重量均保持不变。表明雄兽具有恒定的交配投资模式，这种模式可能起因于该物种雄性之间激烈的精子竞争。

In fact, the total energies for the possible metastable alloy phases of A〓B and AB〓 types of six possible structures were calculated as a function of their lattice constant to find out if the respective metastable phases of A〓B or AB〓 types could be relatively stable in the selected systems. The calculation not only predicted the possible metastable states but also the lattice constant of the corresponding metastable alloy phases of either FCC or HCP structures.
