静电发电机

One of the first to do this was Pieter van Musschenbroek of Leyden, Holland. In 1746 he wrapped a water-filled jar with metal foil and discovered that this simple device could store the energy produced by an electrostatic generator.

第一次去做这项研究的是荷兰 Leyden 的 Pieter van Musschenbroek.1746，他用一个金属箔片包一个装满水的罐子，发现这种简单的设备能储存由静电发电机产生的能量。

Static electricity was the first form discovered and investigated, and the electrostatic generator is still used even in modern devices such as the Van de Graaff generator or MHD generators.

静电是发现和研究的第一种形式，静电发生器即使在现代的设备中仍在使用，如范得格拉夫发电机或磁流体发电机。

In 1660 German Otto von Guericke made the first electrostatic generator with a ball of sulfur and some cloth.

在1660年，德国人 Otto von Guericke 用一个硫磺球和一些布制造了第一台静电发电机。

We do experiment on electret material; and we do package experiment on electrostatic micro-vibration generator. After testing packaged micro generator, we analyze and summarize problems in the preparation of micro generator, and further improve the micro-generator system. The output voltage was 115mV.

对核心材料驻极体进行了实验研究；对静电式微型振动式发电机进行封装实验，；对封装好的发电机进行了测试；分析总结了在发电机制备过程中出现的问题，进一步改进和完善了微型发电机系统，输出电压达115mV。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
