Stable distribution analysis to statistical evaluation of contact resistance in aluminum alloy spot welding;

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.
