The design and make of a simple electric arc plasma generator;2. Mathematics expressions of arc curr en t are deduced considering the circuit resistance of the arc furnace,based on the assumption that electric arc voltage follows rectangle wave,and the elect ric parameters related to continuous and non-continuous electric arc are obta ined.

推导了在假定电弧电压为矩形波条件下，电弧电流的瞬时值数学表达式，明确了电弧连续性与随操作参数I/Is之间关系，推导中考虑了线路电阻的影响；分别求得了电弧连续与不连续情况下的无量纲电气参数；得到了电弧连续性准则；给出了计算临界功率因数的线性高精度近似计算式。

To derive the desired FR construction,'argument skeleton'approach of Lebeaux (1988) is assumed, in which an argument skeleton, an operator-variable construction formed as a result of the operation Move-α, is adjoined to a rooted argument skeleton containing an abstract NP with indefinite meaning.

关于英语自由关系分句的生成，作者移植Lebeaux（1988）的'argument skeleton'理论：一个由于Move-α操作过程而产生的算子-变量结构，作为一个argumentskeleton，与内含一个意义不确定之名词的主argument skeleton接合，即生成一个自由关系分句。

Main job is to guarantee the scraping interaction and equipment on both sides of the friction surface or can obtain higher precision and accuracy, precision and shape accuracy, precision and contact transmission because of good lubrication, manual and repeatedly is worthy, large amounts of wind, time-consuming, scraping the time needed for different devices vary, such as boring slider and slide block wind profiling, between the match before measuring clearance between the original value, and then according to the technical requirement to measure the value of time and scraping scraping, then apply DanFen red on the slider, manual let slip on the slide seat back and forth, they do straight-line movement between full contact and friction, reoccupy scraper scraping friction creates the contact point, so repeatedly, until the technical requirements for the match, single within 2 days, must blow to the boring if all the time to work with wind, a half month is required.

刮削过程。刮削工作主要是为了保证设备相互接触并摩擦的两面间能获得较高的尺寸精度、形状精度、位置精度、接触精度、传动精度和良好的润滑，因是手工操作且需反复配刮，故工作量大，耗时较长，设备不同，刮削所需时间也各不相同，例如镗床上滑座与下滑座间的配刮，刮削前先测量出二者之间原有的间隙值，然后根据工艺要求测算出需刮削值及每次的刮削量，再将红丹粉涂于上滑座之上，手工让上滑座在下滑座上来回做直线运动，使它们之间充分接触和摩擦，再用刮刀刮削摩擦产生出的接触点，如此反复多次，直至技术要求范围之内，单此项配刮需2天左右，若对于整个镗床所有配刮工作的时间总和，则需半个月左右。
