鈦的多孔顆粒 的英文怎麼說
中文拼音 [tàideduōkǒngkēlì]
鈦的多孔顆粒
英文
titanium sponge granules-
That is the premise of the bg / ha electrophoresis codeposition. the laws of the electrophoresis deposition of the bg and ha partic les were found by the study on each of their deposition under the different conditions. the electrophoresis codeposition of the bg and ha particles had been studied and the bg / ha graded coating, which is compact in the bottom layer and porous near the surface layer, had been prepared on the surface of the dental implant after the low temperature heat treatment ( about 740 ) and fast firing ( 50 - 80 / min, heat preservation time was 5 - 8min. )
以bg微粉和ha微粉作為塗層原料，通過研究bg和ha微粉在非水介質中的分散情況和帶電特性，選擇冰醋酸為介質，使分散在其中的bg顆粒和ha顆粒表面均帶上正電荷，為電泳共沉積提供前提條件；通過對不同條件下bg 、 ha各自電泳沉積的研究，探索出了兩者電泳沉積的規律；通過對bg和ha在冰醋酸中電泳共沉積以及后續低溫（ 740左右）快燒（ 50 ? 80 min ，保溫5 ? 8min ）熱處理的研究，在鈦合金牙根種植體基體上成功制備出了底層緻密而表層多孔的bg ha梯度塗層。From the investigation of titania films with peg as additive, several significant conclusions could be drawn : titanium dioxide films with porous microstructure could be prepared using peg as additive ; almost no conglomeration were observed with the titanium particle ; the microstructure of titania films could be modulated by the amount of peg and treating temperature ; at the same time, the porosity of the film improved with the increase of peg ; for the specimen treated at different temperatures, the greatest porosity could be achieved when treated at 500 ? ; the adding of peg could greatly increase the dye adsorption amount
對以peg為添加物的tio _ 2薄膜樣品的研究表明： peg的加入得到了具有疏鬆多孔結構的tio _ 2薄膜，但二氧化鈦顆粒有些團聚。 peg的含量和熱處理溫度對tio _ 2薄膜的微觀結構均有影響。 tio _ 2薄膜的氣孔率隨peg的加入量的增多而增大。( 3 ) with the condition of table 4. 3, with increasing of temperature the average reflectance value decreases and the minimum reflectance point moves towards red direction. furthermore, temperature has little effect on the extinction coefficient ( k ). however, the refractive index value decreases remarkably when the temperature reaches about 240, but it does not change much when the temperature is below 180 and the thickness of the films increase when increasing the temperature
（ 3 ）隨著溫度的增加薄膜的平均反射率降低並且反射低谷向長波方向移動;溫度對消光系數k影響不大;當溫度低於180薄膜的折射率變化不大，當溫度達到240左右時薄膜的折射率明顯降低;薄膜的厚度隨溫度的增加而增加;隨著溫度的增加tio2的晶體結構由混晶變為單一的銳鈦礦相，薄膜的表面的顆粒由多變少，表面形貌由粗糙多孔變得細膩平滑。
