几种均质材料混合测试时
While serveral homogenous materials mixed test
如果将PCB上的电阻制成粉末状来分析,得出的测试数据不能反映真实的情况
The test datum could not show the true situation if analyse from make resistance which under PCB to powder
没有测试到限用的物质
Not detected the limiting material
含有限用物质的均质材料,在混合样品中占的比例非常小
Homogenous material of contained the limiting material,In the mixing samples the proportion is very low
铅含量250ppm
Lead content 250ppm
不含限用物质的均质材料在混合样品中占有的比例较大
Homogenous material of not content limiting material that In the mixing samples the proportion is very high
Is it right
