By using electric probe array with different lengths each other,just in the shape of hedgepig,the free surface(inner surface) velocity history of cylindrical metal tube was measured which was driven by sliding inward detonation.

An electric probe measurement technique of the initial velocities for both preformed and fireformed fragment groupe with velocity attenuation coefficient(α)determined previously is presented.

To study state parameters of methane as atmosphere gas of pins under shock compression, Aluminum target chambers filled with methane gases to a pressure of 0.

I t is shown that ionization degree for argon excessed 1% when the velocities of f lyers ranged from 3 to 5km/s,this ionization may cause pins shortening before fl yers impact pins.

A Rapid Non-destructive Quantitative Analytical Method of Gold in Jewelry by EMPA-EDS;

The composition and microstructure of the failed copper alloy tube in a condenser were studied by means of optical microscope and EMPA.

The composition and structures of ZnSe thin film were studied by EMPA and XRD with the change of temperature of evaporation,temperature of substrate,different substrates and temperature of heat treatment.

Study on Anticorrosion by EPMA in Ancient Bronze Lance of Yunnan;

The Study of Ion Exchange Photochromic Glass by EPMA;

Application of EPMA Image Process Program in Mineral Quantitative;

With a view to the corrosion of the reinforcing steel bars in reinforced concrete,foil-grating resistance probe samples and a device for monitoring of the corrosion of the reinforced concrete were designed and prepared so as to realize online monitoring of the corrosion of the reinforcing steel bars in the reinforced concrete.

The development and application of the resistance probe and testing instrument for high-temperature corrosion monitoring were introduced.

In addition to the positioned thickness measurement, the electro-chemical measurement, resistance probe and inductance probe techniques were also the effective methods in corrosion monitoring.

This paper studies and analyses the key factors which induce fluctuation of corrosion data measured by electrical resistance probe based on principle of temperature compensation,and it was found that the main factos are contact potential between different metals and differential temperature potential due to the temperature drift.

Based on the principle of electrical resistance probe corrosion monitoring,this paper develops ER400 electrical resistance probe corrosion monitoring equipment applied in gas field environment,and the resistance resolution is 0.
