resistance instrument
1.ZHOU Zhai-he, WANG You-ren, KONG De-ming. A high-precision grounding resistance instrument[J]．Automation of Electric Power ystems,2004,28(6)：94-97.
2.Development and application of concrete chlorine ion penetration resistance measuring instrument according to the ASTM C1202 specification
3.NKJ-1 model crop drought resistance identification instrument was manufactured on the basis of continuous rising temperature conductance method(CRTC). put forward first by Chen Yuquan etc.
6.The results show that the device can test the abrasion resistance of yarn accurately, and it will become an advanced instrument for quality inspection and spinning improvement.
8.Abstract: The crook measurement can be made by using metal resistance strain gauge sensor,the digits can be displayed on the three-bit liquid crystral display.A new instrument-digits displayed moment spanner is also designed.
9.「The alloy boasts good shaping property, high corrosion resistance, weldability and fatigue strength,medium static strength, is used to make airplane oil tank, oil pipe, oil pipe, metal sheet and instrument for vehicle and vessel,street lamp post and riveted wire.
10.According to the principle of resistance power and driving power being equal in amounts, the key parameter, the greatest acting force acted on the active tooths by the revolving arm ball bearing of the shock wave instrument is resulted.
