This paper discussesd the preparation of glage-trace element fertiliar.Main raw material-glass and some trace element were put into together,when the reactants were melt,they occur solidoid reaction.

玻微量元素肥料,是以玻为主要原料,加人适量的微量元素,经过灼烧为熔融状态后,发生固相反应,即生玻微量元素肥料。

On the basis of the above analystic results, successful butt cold welding has been obtained between the metals of incoherent lattice and non-soluble liquidoid and non-soluble solidoid.

根据上述分，实现了非共格金属间及液相、固相不相溶金属间的对接冷压焊。
