Surface Specific Resistance

Aluminum Oxide Specific gravity 2.4 Moh hardness 3. More a filler than an abrasive. Tends to fade, but has good wear resistance. Will polish the opposing surface.

氢氧化铝比重2.4莫氏硬度3。比磨料加得更多的填充物。有衰退趋势，但耐磨性好。将抛光对偶。

The results show that the specific surface resistance of the PET film decreases regularly with increasing implanting dose and growing temperature.

结果表明，随离子注入的种类不同、剂量的变化、温度的升降，PET膜的表面电阻率呈规律性变化。

Thus obtained was a high performance getter strip with high specific surface area, high resistance of thermal shock and good endurance of mechanical vibration.

所得带材是一种具有高比表面，高抗热震性和耐机械振动的高性能吸气材料。
