The findings bring new lights in the fluctuating nature of momentum exchange coefficients and integraltime and length scales. These turbulent properties should not be assumed constant.
这将为波动特性的动量交换系数及积分时间和长尺度提供新的信息，这些湍流特性不应被视为不变的。

An integral system is presented based on a microcomputer data acquisition, which can be used in on line checking of the timeconstant of thermocouples and measuring of dynamic temperature.
