这种不稳定性可以通过在胶体表面覆盖蛋白分子比如免疫球蛋白来抑制。

This instability can be prevented by coating the colloidal surfaces with protein molecules such as immunoglobulin.

因此，辊子表面有极高的硬度、脆性及热不稳定性。另外，由于高的硬度使之具有高的裂纹敏感性。

Therefore, the roll surface is extremely hard and brittle and it is thermally unstable. In addition, it is highly crack sensitive because of the high hardness.
