Owing to the common expression of EGF in various organs of mouse,it could be deduced that the role of EGF was mainly autocrine and paracrine actions,and its endocrine role was also not excluded owing to its high expression abundance in submaxillary gland.

由于EGF在小鼠各器官中表达的普遍性，可以推测EGF的作用以旁分泌和自分泌作用为主，但它在颌下博士学位论文"TnEGFAlelittin"嵌合基因构建及有关基因重组表达的研究等器官中的高表达表明其也具有内分泌作用。

The properties of TCC with ATS were as good as the TCC with HTS, better that the requirement of standard GB8744-88 for semi-graphitic carbon block.AbstractAs good as TCC with HTS in industrial cells, the TCC with ATS also reduces the sodium penetration to cathodic lining, no tear-off of the coating was found after starting up of the cells.As compared with reference cells, the operation of coating cells with ATS was also improved to keep good shape of cell chamber, reduce the formation of sludge on the cell bottom, and gain more uniform current distribution. The ohmic drop of TCC cell bottom was lessened by ll.SmV. The current efficiency was increased by about 1 .48% in average. It was estimated that the TCC life could be 44 months.Obvi

对常温固化涂层槽的考核表明，与高温固化涂层槽一样，阴极内衬对钠的吸收减少，钠渗透速度减缓，从而减小钠膨胀危害，减少了博士学位论文摘要铝电解槽早期破损的几率；启动后，常温固化涂层不脱落，同样具有良好的粘接性能；与对比槽相比较，常温固化涂层槽正常生产后，阴极表面干净、光洁，无沉淀或结壳，炉膛规整，阴极、阳极电流分布均匀，炉底压降降低(平均降低11.smv)，电流效率提高(平均提高1.48%)；涂层在电解槽内存在的时间可达到44个月以上；常温固化涂层同样可以起到改善电解槽工作状态、节能降耗、延长槽寿命的作用。
