你可以先用专业的翻译工具来直译一下，然后再看看如何措词，我想你是搞这个专业的，应该有一些专业英语功底，我太忙，没时间帮你翻译了！

Finite element analysis computing mode of bimaterial interfacial crack extending is created in porcelain-fused-to-metal-restoration.

摘要建立金瓷修复体双材料界面裂纹扩展的有限元计算模型。

Because three differences lie in the pearlite to have the round arc crack which the condensation forms, calls the pearlite structure, the water content 2~6%; The pitchstone has the unique resinous luster, the water content 6~10%; The black sunlight crag has the glassy luster and the conchoidal fracture, the water content is smaller than 2% generally.

三者的区别在于珍珠岩具有因冷凝作用形成的圆弧形裂纹，称珍珠岩结构，含水量2~6%；松脂岩具有独特的松脂光泽，含水量6~10%；黑曜岩具有玻璃光泽与贝壳状断口，含水量一般小于2%。

A549 cells are more sensitive to CDDP-induced apoptosis(P.01) and less sensitive to THP andβ-Ele-induced apoptosis than A375p(P.01, P.05 respectively). Condensation and crack of nucleus and apoptotic bodies appeared in apoptotic cells of A549 and A375p cell lines in all treated groups and necrocytosis were to be seen in some groups. Fluorescence imaging experiments demonstrated that accumulation of iASPP in cytoplasm but little distribution in nucleus in all groups. untreated groups in two cell lines presented a bright-green colour,followed by CDDP-treated groups,and THP-treated groups is the darkest one in all groups.

免疫荧光显示，未加药物处理的A549和A375p细胞胞质染色均匀呈亮绿色，核区较暗；CDDP及β-Ele处理组细胞为暗绿色，其中可见皱缩的凋亡细胞；THP处理的细胞胞质荧光弱呈灰绿色，由于THP嵌入DNA自发红色荧光与二抗的绿色荧光中和，胞核被染成桔红色，结果提示药物处理后A549和A375p细胞中iASPP的表达有不同程度的下降。

The way of crack elimination is by setting the vertex of higher resolution node to the edge of conterminous lower resolution node.

另外，通过将较高分辨率地面块边界点移到相邻较低分辨率地面块节点的边界上的方法消除裂缝。
