之后他们压缩减压能产生声波的这种气体。数据表示部分冷凝物的速度超过声速，因此他们制出了声音的黑洞边界。
Their data showed that the speed of part of the condensate exceeded the speed of sound, and they had therefore made an acoustic event horizon.
倾斜式回流冷凝器中溢流速度随倾斜角度而变化，当倾斜角在30至50之间时，液泛速度达到最大值。
The flooding velocity in an inclined reflux condenser varies with the inclination and may reach the maximum value when the inclination is between 30and 50.
这些参数包括冷却速度、耗电量、冷藏室温度、冷冻室温度、冷凝器温度、压缩机吸气温度和排气温度等。
Those parameters included pull down speed and power consumption of the refrigerator, temperature of cold storage chamber, freezing chamber, condenser, suction and discharge pipes of compressor, etc.
对于冷凝器和蒸发器，计算速度较分布参数模型均提高两个数量级。
For condensers and evaporators, the computational speed with the new model is about two orders of magnitude faster than that with the distributed-parameter model.
结果表明，空塔速度对冷凝效率及成酸浓度影响最大，冷凝器出口温度次之。
The results showed that the condensation efficiency and the sulphuric acid concentration were affected by superficial velocity considerably, then the condensation temperature.
