In this research, we prepared Mo doped ZnO thin films on glass a substrate using co-sputtering to improve the conductivity of ZnO. The incorporated concentration of Mo atoms in ZnO was controlled by adjusting the aperture size of a shutter palaced in front of the Mo target. Textured morphology of ZnO film could be formed by attaching a metallic mask on the substrate.

本研究，欲以钼(Molybedeun， Mo)金属掺杂来提升氧ZnO薄膜之导电性，使用一般玻璃做为基板，利用射频溅射ZnO靶材及直流溅射Mo靶材进行共镀，Mo掺杂浓度是藉由钼靶前之挡板中的开口大小来控制，实验中改变基板温度(50℃、100℃、200℃、300℃)并进行镀膜后低压退火处理，藉此探讨Mo掺杂对於ZnO薄膜光电特性之影响，并找出最佳化制程参数。

将读取数据导入Pro/E软件中，先将桩核冠进行参数化（参数包括桩核冠的直径、长度、锥度、倒角等等），同时根据桩核冠的参数，分别建立可随桩核冠参数变化而自适应变化的饰瓷、金属基底、粘固剂、牙本质、牙胶尖、牙周膜、松质骨和皮质骨的实体模型。

This pattern is characterized by the combination of pro-MMP-2 and membrane type 1 (MT1)-MMP expression, which drie pericellular generation of actie MMP-2 and local degradation of normal lier matrix. In addition there is a marked increase in expression of TIMP-1 leading to a more global inhibition of degradation of fibrillar lier collagens by interstitial collagenases (MMP-1/MMP-13). These pathways play a significant role in the progression of lier fibrosis.

其降解肝正常基质，同时抑制引起肝纤维化的纤维胶原降解，这种情况的特点是前明胶酶A合成和膜型1－MMP表达，使得小叶内细胞激活MMP-2和降解当处的正常肝基质，此外血浆1型组织基质金属蛋白酶抑制剂（TIMP-1）明显升高引起广泛的抑制间隙胶原酶(MMP-1/MMP-13)对纤维肝脏胶原的降解。
