Plasmodia ofPhysarum polycephalum were analyzed with the aid of cinematography and the infrared reflection technique for characterization of the phase behavior of their oscillating contraction activity, with special emphasis placed on the effects of temperature gradients. In response to temperature gradients, phase gradients were documented cinematographically as well as by infrared registration. A quantitative evaluation of the cinematographically recorded phenomena was carried out with the aid of streak photography. The phase gradient is directed across the region of the temperature gradient with a delay in phase toward the colder side. The correspondingly generated waves are as short as 1 mm and are propagated toward the colder region. A comparison of these waves with the known "flickering" phenomena in cinematographic films reveals a common nature of both.
用电影摄影术和红外反射技术分析了多头绒泡菌的疟原虫，以描述它们的振荡收缩活动的相行为，特别强调了温度梯度的影响。响应温度梯度，通过电影摄影术和红外记录记录了相位梯度。借助于条纹摄影术对电影记录的现象进行了定量评估。相位梯度沿温度梯度的区域指向冷侧的相位延迟。相应产生的波短至 1 毫米，并向冷区传播。将这些波与电影胶片中已知的“闪烁”现象进行比较，揭示了它们的共同本质。
