This paper introduces a technology process for vacuum pouring of cooling liquid system of projection tube, analyzes the specific realization method, determines the final scheme on basis of comparing the schemes.

This paper introduced a few of methods of hydrogen storage,including compressed hydrogen,liquidized hydrogen,metal hydrides,carbon nanotubes,organic liquid hydrides storage,and commented their recent developments,and pointed out direction of hydrogen energy storage progress.

According to the result, the joint which will be avoided crystallizing should be in supercooled liquid with good thermal stabilization, superplasticity and viscous flow, at the same time, the temperature of the joint should always be under the crystallization temperature of the BMG.

As a result,this can be an evidence that the transformation from the glassy state to supercooled liquid belongs to second-order transition.

It is shown that the rapid viscous flow deformation, forming, welding can be carried out in the supercooled liquid region.

The glassy alloys exhibited distinct glass transition together with supercooled liquid region in the range of 38～65?K.
