瘤细胞表面的抗原密度影响细胞毒的敏感性。
Antigen density on the tumor cell surface influences the cytotoxic sensitivity.
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.
过高的注塑速度会引起较高的表面方向性及增加应力破裂的敏感性。
Excessively high injection speed can cause high surface orientation and increase susceptibility to stress cracking.
