Project Introduction: Trichlorosilane, also named Silicochloroform ,is mainly used in the synthesis of organic silicone, alkyl, aryl and organic functional group chlorosilane. It's the most basic monomer of the organic silane coupling agent,and the production material for semiconductor silicon and silicon; Manufacturing process of the tetrachlorosilane includes the reciprocal effect by the trichlorosilane steam and the hydric steam which has been heated up to 1700-2500SiCK by the plasma accelerator; the steam compound in the reactor goes into the condensing system that separates trichlorosilane. After that, polycrystalline silicon can be made.

After the application of this model to the MITL-A of Sandia Z-accelerator, it is found that: the formation process of magnetical insulation leads to the increase of line current and the decrease of line voltage; If the initial line current is infinite, the terminal line voltage and current are almost the same as the initial ones; If the ratio of the terminal space-electron current to the terminal line current is less than 10%, the change of terminal line voltage and current of the MITL-A relative to the initial is less than 5%.

将模型应用于Z加速器的MITL-A发现：磁绝缘形成过程将导致线电流增加和线电压降低；如果初始时刻的线电流无限大，则终止时刻的线电压和线电流与初始时刻相同；当终止时刻的空间电子电流在线电流中的比例小于10%，则MITL-A终止时刻的线电压和线电流较初始时刻的变化在5%以内。

The common thread present in most all works by Marnix de Nijs is the fact that a man, an observer, a participant is brought into challenging situation – the atmosphere of a demolition in Pump it, the fear of explosion of the last gallon of oil in Autonomous Oil Reserve, the vibration and a sense of instability created by The Thrillmachine, the unexpected resistance of a machine controled by other human in Push and Pull, the loss of privacy from wiretapping in The Sound of Neighbours and nausea in Panoramic Accelerator.

Marnix de Nijs的大部分作品都有一个共同点，就是观众必须被带入具有挑战性的环境中-&抽它&的毁灭氛围，&自动石油储备&对最后一加仑石油爆炸的恐惧，&兴奋机器&的振动和不稳定感，&推拉&由他人所控的意外的机器阻力，&邻里之声&因窃听丧失的隐私权，&全景加速器&的恶心。
