The Effection of Discharge Current on Hydrogen Plasma in the Cascaded Arc Jianglong Li1, a, Honglei Hao2,b 1,2COLLEGE OF SCIENCE GUIZHOU UNIVERSITY,CHINA 1,2 The East Road high tech Zone Weifang city Shandong province China No. 268 ashawn.yim@foxmail.com, bIvy.hao@goertek.com Keywords: Hydrogen plasma, Electron temperature, Electric conductivity, DC arc discharge, Electron density.
Introduction The interaction between High-Density Plasma and Plasma Facing Materials is a popular issue in the research fields of International Thermonuclear Experimental Reactor.[1] In some countries, their scientists have built their own plasma generator to do this research, like the PISCES- B[2]which is in America and Polot-PSI[3] in Netherlands.
Discussion of the influence of discharge current on hydrogen plasma in the cascaded arc is rarely been reported on the journal.

For the traditional configuration of the shovel, if not timely adjust the length of the bucket hydraulic cylinder, in full in the process of ascension, bucket can along with the rising of the movable arm swing Angle and backward tilting, easily happened on dangerous materials, and so require horizontal bucket has remained in the process of ascension.
In order to ensure that the material is full of bucket, bucket ascend initial state should make BF attachment level, as shown in Fig. 1.The kinematics model is established by Denavit Hartenberg method, point B and F point ordinate expression (1) Fig.1 Power triangle bucket level state In the process of ascension, to always keep the bucket level ascension, apparently bucket attachment BF parallel to the horizontal line is always, its Angle, namely the guarantee type (2) is set up (2) The content type (3) (3) Notice bucket ascends the bucket rod and bucket hydraulic cylinder hydraulic cylinder generally keeps it locked, was constant, desirable arm half maximum pendulum Angle.

When ultrasonic pulse launched by probe arrives Material interface through the object to be measured it would be reflected back to probe, then by measuring the travel time of ultrasonic accurately we can determine the thickness of the measured material.
The speed of sound is constant in the certain material, and the computational method is as formula (2) (2) In the formula (2): is the elastic modulus of the material.
