Compared the sample test result of two kinds of methods, It proves the meth - od that flame atomic absorption spectrometer determinates Pb, Cr, Ni in stainlesssteel food container is feasible.
同时比较了两种方法的样品测试值，证实火焰原子吸收光谱法测试不锈钢食具中的铅、铬、镍切实可行。

The results showed that: the amounts of releasing ions per second, Al-V-Ti alloy was the least, followed by 3 kinds of stainlesssteel, Ni-Cr alloy, Cu alloy.
结果显示：每秒钟释放的离子数，以铝钒钛合金最少，3种不锈钢次之，镍铬合金较多，铜合金最多。

The microstructure and wear resiStance of laser cladding layers of Ni and Cr onthe surface of stainlessSteel were studied.
