On the contact resistance between graphite/polypropylene composite plate and carbon paper;

Study of prediction method for contact resistance based on experiment constitutive relation;

The electrochemical methods were investigated in a simulated PEMFC environment and the volt-ampere technique was applied to measure interfacial contact resistance between the sample and carbon paper.

The 304 stainless steel treated by electroplating Cr and plasma-assisted nitriding processes was investigated by electrochemical methods in the simulated PEMFC environments, and interfacial contact resistance between the samp.

The interfacial contact resistance between the sample and carbon paper are measured with volt-ampere technique.

In order to reduce contacting resistance of bridge shaped contact and lower down temperature rise,improvement design was carried out for DW450-1100 universal circuit breaker bridge shaped structure.

In order to determining the fire risk of plug and receptacle in different connecting resistance,the plugs rated 10 A and 16 A are used to study the temperature rising in the different contacting resistance and current.

In order to reduce the contacting resistance of contacts,to reduce temperature rise of contacts,improved design was made to the structure of contact.

Two contact models,the classical Coulomb contact model and the modified Coulomb contact model,are used in a fully coupled thermo-mechanical numerical model of friction stir welding, and the suitabilities of the two models to simulate the welding process are analyzed.

Based on the first-order shear deformation theory of the composite laminated plate,an FEA model and the method of free vibration analysis for the composite laminates with multiple through-width delaminations were developed,and a linearity contact model was established to simulate the interaction between upper and lower sub-laminates along the delaminated region during the vibration process.

Fractal surface was introduced into the average flow model and effect of elastic-plastic contact deformation of fractal surfaces on the flow factors and contact factor were analyzed based on the M-B fractal contact model for partial film lubrication.

Calculation of specific contact resistance in ohmic contacts;

But Ohmic contacts on p-type GaN with low specific contact resistance are more difficult to realize than those on n-type GaN.

The measurements of the specific contact resistance ( ρ c) were carried out for Ti/Au ohmic contact to heavily boron\|doped p\|diamond (～10 20 cm -3 ) by the transmission line model (TLM).
