In consideration of the characteristics of arc motion, the authors have used tree methods of high-speed photography in a number of experiments where the arc moves in the transverse magnetic field. A comparison has been made between the three methods with respect to their advantages and disadvantages as well as applicability.The phenomena of arc initial immobility, immobility of arc roots during arc motion, motion of arc column and extinguishing of the arc have been observed by the third method. It is noted that...

A marked seasonal reproductive diapause has been observed in the rice leaf roller in all the outbreak regions in China. The occurrence of reproductive diapause coincides with the seasonal emigratory periods in different regions.

A marked seasonal reproductive diapause has been observed in the rice leaf roller in all the outbreak regions in China. The occurrence of reproductive diapause coincides with the seasonal emigratory periods in different regions. In this experiment, investigations were carried out under artifitial simulant conditions to explore the ecological signals that may induce seasonal reproductive and migration with a view to the forecasting of migration. Tests on the three factors—temperature, photoperiod, and food—including eight treatmentes were carried out in 1980. The results were as follows:1. In all the treatments, food showed no significant effect on the reproductive diapause and migration. However, so far as the mean developmental speed of the female ovaries is concerned,that in the females feeding on rice plants in the heading stage was a little slower than that in the individuals feeding on rice plants in the tillering stage.2. Short photoperiod and high temperature were found to be the key factors in inducing reproductive diapause and emigration, and the two factors conditioned each other.In contrast to the natural conditions, under the long photoperiod condition in summer, high temperature is the major factor that induces emigration,while in autumn when the temperature is relatively low,short photoperiod becomes the dominent factor in inducing emigration.

稻纵卷叶螟在我国各发生区域内都有明显的季节性生殖停滞现象,而这种生殖停滞的时期也正在与各区域内季节性迁出的时间相吻合。本文是在人工模拟条件下,探索引起这种季节性生殖停滞或迁飞的生态信息,以期达到予测迁飞的目的。 在1980年进行了温度、光照周期、食料条件三个因素的8个处理的试验,结果表明: 1、无论在什么处理下,食料对生殖仃滞或迁飞均无显著影响。虽然从卵巢发育的平均速度来比较,取食抽穗期水稻的个体卵巢发育稍慢于取食分蘖期食料的。 2、各处理下的分析表明,短光照和升温是诱发生殖仃滞或迁飞的主导生态因子,二者并有相互制约的效应。 对照自然情况,夏季长光照条件下,高温是诱发迁出的主导因素,而在秋季降温条件下,短光照是诱发迁出的主导因素。

By making use of the edge effect of arc motion and controlling the arcing path through the adoption of narrow electrodes, the first quasi-immobility effect and the second high-speed effect of magnetically driven arcs have been observed.It has been found that no first quasi-immobility effect occurs on polished clean electrodes. The velocities of the first arc run are very high and can reach the order of magnitude of those in the second run. Experiments on polished clean electrodes show that the arc run velocities...

By making use of the edge effect of arc motion and controlling the arcing path through the adoption of narrow electrodes, the first quasi-immobility effect and the second high-speed effect of magnetically driven arcs have been observed.It has been found that no first quasi-immobility effect occurs on polished clean electrodes. The velocities of the first arc run are very high and can reach the order of magnitude of those in the second run. Experiments on polished clean electrodes show that the arc run velocities after the second run are all of the same order and are independent of whether the electrode surfaces are clean or oxidized. The experimental results are briefly discussed.

本文对磨光清洁表面的电极是否存在首次似停滞效应及第二次高速效应进行了实验研究.文中指出,表面磨光并擦净的电极不存在电弧首次似停滞现象,电弧首次运动速度可达到第二次速度的数量级.实验结果还表明,二次后的各次跑弧速度均有相同的数量级,且与电极清洁或氧化等原始条件无关.文中通过对自然氧化达到两年的窄面电极进行的实验研究,进一步肯定了磁驱动电弧首次似停滞效应及第二次高速效应的非随机性.
