1.Choose the cable type according to power supply condition and power net load ,decide if use parallel connection or series connection type cables, single phase or three phase type cables.
2.After electric heating system is installed,check electrical insulation of all circuits.The insulation resistance between generatrix and shielding layer,core wires of series cable before connection at end not be less than 20 MΩ.And then check if DC resistance of circuit is normal and phase resistance is banlance.
3.Tyco Thermal Controls is the world leader in providing heat tracing and heat management solutions for the industrial, commercial, and residential markets and in offering fire-resistant &high performance wiring solutions as well.
4.Electric heating products have all-weather proof capacity.When installing,pay attention to easy maintenance,tidy and good looking and no rain and snow will be collected in future use.
5.IF electric heating pipes are put into operation firstly,preheat the pipes to the maintenance temperature of media,then open valve.
6.This paper introduced the present condition of fuse salt electric tracer heating temperature control in the introduced project "tubedigestion" of China wall aluminium corp. using japanese mitsubishi A2 serial programmable controller to achieve the practice process of molten salt electrcity heat tracing temperature control system,the composition of system and main function.
7.The percentage of bilateral abnormal ECoG with tinnitus was 23.1%(9/39). In comparison,there was only 2% (1/51) patient suffering tinnitus on the contralateral ear with abnormal ECoG on one side. The positive rate of bilateral abnormal with bilateral tinnitus was higher than that of the abnormal ECoG on one side with contralateral tinnitus (P<0.01).
8.Objectives: To investigate the value of ENG on differential diagnosis of disease with dizziness diseases Methods: The recordings of ENG, including spontaneous eye-quate and gaze test, optokinetic nys- tagmus positional and caloric test, from 575 individualities with dizziness diseases.
9.Conclusion The induced 2:1 AVB during AVNRT is due to functional block in the His-Purkinje system regardless of the presence or absence of a His bundle deflection in blocked beats.
10.1. Both EA and maprotiline were effective in the treatment of major depression. For endogenous depression maprotiline is better.
