space-charge current

In this paper, the space-charge limiting current of coaxial drift tube is derived by the Green's function method.

At the same tank voltage, the current density decreases with the space between electrodes increasing.

在槽电压V相同时，随着电极板间距的增加，电流密度逐渐减小。不同电极板间距下铁电极的i-V曲线均呈现良好的线性关系。

This function checks to see if there is enough space on the current page to print another row, and ejects the page if not.

这个函数检查看当前页是否有足够的空间来打印另外一行，如果没有，则离开当前页。

That's why this new policy also includes directions to update the current U.S. Government Orbital Debris Mitigation Standard Practices, which already require any entity that launches a satellite or spacecraft to vigorously analyze the likelihood that any of their actions, from an unexpected failure or normal operations, will create more space debris.

这就是为什么这项新政策还包含了更新美国政府现行轨道碎片减缓标准的指导方针，该方针要求发射卫星或航天器的任何实体积极分析其所有行动产生空间碎片的可能性，无论是意外故障还是正常操作。
