Surface tension measurements can be performed optically using apendant drop shape analysis. The shape of the drop hanging from a needle is determined from the balance of forces which include the surface tension of the liquid being investigated. ...
ato verify the transferability of the test results to the pratice, the running resistance of a conveyor belt was determined in field measurements on a running system 要核实测试结果的转移性对pratice,传送带的连续抵抗在野外测量在一个连续系统被确定[translate]...
Interfacial tension measurement between two immiscible liquids is based on thependant drop methodwhere a drop of liquid is formed at the end of the needle tip. In the interfacial tension measurement instead of having air as the surrounding phase, the droplet at the needle tip is immersed in ano...
Because the mechanical inertia and dampening effects of an electromechanical meter movement makes the deflection of the needle naturally proportional to the average value of the AC, not the true RMS value, analog meters must be specifically calibrated (or mis-calibrated, depending on how you look ...
Variability in long-term endovascular treatment outcomes for intracranial aneurysms has prompted questions regarding the effects of these treatments on ane
Gas inlet line 35 is usually connected to a gas mixing manifold (not shown) and includes toggle valve 36 and needle valve or mass-flow controller 38 that permit semiconductor wafer process gases to enter semiconductor processing apparatus 10. Translation compartment 40 receives semiconductor wafer ...
The measuring needle comprises a metallic needle point (1) enclosed by an insulation layer (2) over part of its length, with a metallic layer (3) applied to the insulation layer. The metallic needle point may be insulated by an insulating lacquer applied by dipping or spraying, or by ...
As main counter, a gas needle counter, working in conditions of deep reduced proportionality is used. The counter characteristics and experimental as well as theoretical results of the gas amplification analysis are given. The detection efficiency is equal to 100 per cent in the case of samples ...
