Based on the homogeneous model, the numerical computation for the oscillation period and amplitude of pressure drop type instability was conducted.

根据两相流的均相模型，对压力降型脉动的周期和振幅进行了数值计算。

The pressure drop pulsation is analyzed by using a lumped parameter nonlinear model. The results show that the pressure drop type instability can be described by a second-order differential equation.

使用集总参数非线型模型来分析蒸发管中汽液两相流压力降型脉动，结果表明：压力降型不稳定性可以用二阶常微分方程来描述。

For decades astronomers have suspected the existence of a type of stellar explosion that is bigger still-a "pair-instability" supernova, with 100 times more energy than an ordinary supernova.

数十年来，天文学家们一度怀疑一种更寂静的恒星爆炸的存在——称之为“对不稳定”超新星，其能量超过普通超新星100倍。

As a result, even if widespread vote fraud (which those like Jimmy Carter will nonetheless indubitably call "substantially free and fair elections") does not produce grave domestic instability in Russia, it will almost certainly accelerate the Kremlin's reversion to malevolent type internationally.
