An inductor whose case has been formed via a molding process , common molding processes in clu - de injection and transfer molding , molded inductors typically have well defined body dimensi - ons which consist of smooth surfaces and sharper coners as compared to othercase types such as epoxy coated and shrink wrap coatings ( also see inductor 外壳以铸型掉程所成形之电感，通常铸型制程包括射出及转移铸型两种，与其他型式之电感如环氧权脂包覆的电感及伸缩套管之电感比较起来，铸型电感常有很明确的尺寸，平滑的表面及尖锐的边角。
But the active silver substrate of sers used in the study of the cathode material cannot be used in positive electrodes . in the lithium ion battery the working voltage of positive electrode may reach and exceed 4 . 0v , however the silver will be oxidated at 3 . 6v ( vs li / li + ) , and in the first charge process , the nanometer silver can be dissolved into the electrolyte and no longer has sers active 但银衬底却不能应用于正极材料表面sei膜的研究当中,因为锂离子电池中正极的工作电位可达4 . 0v以上,而银在3 . 6v ( vsli / li + )附近就开始发生氧化反应,在第一次充电过程中,正极材料表面包覆的银颗粒就会因电化学反应溶入电解液中,不再具有表面增强的效果。
On this paper , a chemical deposition technique is studied to coat tih2 with al2o3 , which increase the releasing hydrogen temperature of tih2 and delay the decomposed times of tih2 in melt aluminum clearly as compared to uncoated tih2 by tested in laboratory . according to the result of test , an al2o3 - tih2 通过扫描电镜以及能谱分析证实了包覆效果，通过释氢试验对比了包覆层对tih _ 2发泡剂释氢特性的影响，优化了包覆工艺，并采用包覆的发泡剂在实验室进行了泡沫铝制备工艺实验。
