Angstrom unit : A unit of measurement of the length of light waves . It is equal to 1 / 10 of a millimicron .
埃：量度光波长度的单位。一埃等于十分一毫微米。
Conclusion The cytotoxicity of millimicron brucite fiber was obviously stronger than common brucite fiber , but much weaker than quartz dust .
结论纳米级水镁石纤维粉尘具有明显的细胞毒性，其细胞毒作用较普通水镁石纤维粉尘强，较石英粉尘弱。
Recently , cleaning should remove not only organic matter on silicon surface , but also the particles of millimicron order and ppt metallic ions .
目前清洗不但要去除硅片表面的有机物而且需要去除的颗粒尺寸已经达到了纳米级，金属离子达到了ppt级。
