  公开（公告）日：1989-07-05

  The method comprises placing test solutions and a buffer solution separately in a cell made of a material that is pervious to laser rays; transmitting a laser beam through each of the solutions in the cell while it is exposed to thermal radiation from an object held at a temperature higher than that of the test solution; measuring expansion of laser beam for measuring degree of fluctuation in liquid structure, by the use of horizontal position of photoreceiver at the rise part of scattering profiles; plotting the relative position of a photoreceiver against the concentration of substance being tested; and evaluating the physiological activity of the substance from the pattern of graph prepared above. An apparatus for evaluating physiological activity is also claimed.

  该方法包括：将测试溶液和缓冲溶液分别放入一个由可透射激光射线的材料制成的池中；在池中的每种溶液暴露于来自温度高于测试溶液温度的物体的热辐射时，发射一束激光；在散射曲线的上升部分利用光接收器的水平位置测量激光束的膨胀，以测量液体结构的波动程度；绘制光接收器的相对位置与被测物质浓度的曲线图；以及根据上述绘制的曲线图评估物质的生理活性。 本发明还要求获得一种评估生理活性的装置。
