Abstract
- In case Cerianthus is acted upon by two lights of unequal intensities the relation between the angle turned and the ratio between the intensities of the two lights is mathematically expressed by the equation log(10) See PDF for Equation tan a, in which See PDF for Equation is the ratio of the two lights, a is the angle turned from the neutral position, and K = 0.615. 2. According to published data from experiments on other animals, the relation between the angle turned and the ratio between the intensities of the two lights may be expressed by the same equation.
摘要
如果 Cerianthus 受到两个不等强度光的作用，那么角度的变化与两个光的强度比之间的关系可以用方程 log(10)tan a 来数学表示，其中 See PDF for Equation 是两个光的强度比，a 是从中性位置转过的角度，K = 0.615。
根据其他动物实验的已发表数据，角度的变化与两个光的强度比之间的关系可以用相同的方程表示。
