natural oxide film造句

• The biological properties of titanium implant depend on its surface oxide film . because the natural oxide film is bioinert , titanium is generally bioactivated by modifying oxide film or coating ca - p layer
  自然生成的钛氧化膜是生物惰性的，为赋予钛生物活性，通常对表面氧化膜进行改性或在其表面涂覆羟基磷灰石涂层。
• The tritium permeability in 316l with films was measured at various temperatures , the results show that the tritium permeability in 316l with tin and natural oxide film are 2 orders of magnitude lower , that in 316l with sio2 is 3 - 4 orders of magnitude lower , that in 316l with tin + tic + tin is 4 - 5 orders of magnitude lower , and that in 316l with tin + tic + si02 is 4 - 6 orders of magnitude lower than that in 316l with pd film , at 200 - 600 ?
  测量了不同温度下的带膜316l的氚渗透率，发现在200 600范围内，镀tin膜与带天然氧化膜的316l性能相近，均比镀钯316l降低2个数量级。镀sio2膜比镀钯316l降低了3 4个数量级，镀tin + tic + tin膜降低4 5个数量级，镀tin + tic + sio2膜降低4 6个数量级。
