1.1. 本文描述了一种用于研究海胆卵原生质稠度的磁颗粒法。该方法的原理是将球形铁颗粒放入卵中，然后借助外部磁场使该颗粒在原生质中移动。根据粒子对施加力的反应，可以确定原生质的力学性质。海胆卵的原生质是粘弹性的。原生质的性质可以用一个Voigt单元和一个串联的粘性单元组成的粘弹性模型来近似表示。给出了粘弹性常数的近似值。讨论了本研究结果对原生质结构的影响。
1.1. A magnetic particle method is described for the study of the consistency of the protoplasm of the sea urchin egg. The principle of the method is to get a spherical iron particle into the egg and then to move this particle in the protoplasm by means of external magnetic fields. It is possible to determine mechanical properties of the protoplasm from the response of the particle to the application of the force.2.2. The protoplasm of the sea urchin egg is visco-elastic. The properties of the protoplasm are approximately represented by a visco-elastic model consisting of a Voigt element and a viscous element connected in series. Approximate values of visco-elasticity constants are presented.3.3. The bearing of the present results on the structure of the protoplasm is discussed.
