在假定岩石体积模量是其上、下限值线性加权平均值的条件下，提出了泥质岩石油气层声波速度校正法。

And a correction method for acoustic logs from shaly sand is also proposed assuming that the bulk modulus of the rock is the linear weighted averages of its upper and lower limits.

方法：经颅多普勒超声测定血流速度，同步记录血压，改变血压，绘制脑血流自动调节曲线，并进行分类和确定自动调节的上、下限。

METHODS: The blood velocities and blood pressure was recorded simultaneously and the curves of CBFA were analyzed and classified into classical and non-classical pattern.
