1·The reasons for this phenomenon and the influence of the sulfide scale demixing on the sulfidation process of Fe-Cr alloys have been discussed.

文中讨论了这种现象的原因以及硫化层分层对铁铬合金硫化行为的影响。

2·Methods The defect area and position was located according to skull fault X-ray. The donor bone was made and demixing suture and pressed with gauze.

方法采用颅骨断层X光片了解颅厚度，依据缺损范围确定所取颅骨外板的面积与部位，制取供骨并做相应处理后分层缝合，加压包扎。

3·This demixing effect leads to the difficulties in the control of alloy composition of coating and in the design of composition of alloy cathode target.

这种离析效应导致了合金涂层成分控制及合金靶材成分设计的困难。
