梯度溶劑 的英文怎麼說
中文拼音 [tīdùróngjì]
梯度溶劑
英文
gradient solvent-
In this dissertation, mgo5 is introduced to form solid solution to restrain the decomposition of at in high temperature. then at is mixed with the al2o3, forming gradient composite to raise the integral intensity of the material and not affecting the thermal properties. the experimental results show that the additive mgo5 can effectively restrain the decomposition of at and promote the sinter process, which enhances the density of at
本文在充分分析本領域國內外研究現狀的基礎上，首先通過引入添加劑鈦酸鎂（ m2t ） ，使其與鈦酸鋁形成固溶體，以達到抑制鈦酸鋁中溫分解的目的；再通過與強度高、氣密性好的氧化鋁進行梯度復合來提高整體材料的強度並能彌補鈦酸鋁滲透性能差，同時對材料的低熱膨脹性能影響不大。Solvent gradient elution chromatography
溶劑梯度洗脫色譜法In this work, pluronic f127 was used as a progen and different biodegradation rate and surface property as amorphous calcuim phosphate, a - calcuim triphosphate, - calcuim triphosphate and a / p - calcuim triphosphate were selected to make three - dimensional porous composites with plla. in the phase separation of pure plla or cp / plla composite system the ppo block of pf127 can aggregate plla clew to induce phase separation. this resulted big round pores of 50 ~ 300 m and uniform ladder - like structure of 400 ~ 1000 m
具體結果如下：浙江大學碩士學位論文在單純的聚乳酸以及鈣磷酸鹽/聚乳酸復合體系的相分離過程中， pf127的ppo鏈段對plla鏈段有聚集作用，促進相分離過程，在不同溶劑中分別可得到孔徑在50一300林m的較大的圓孔和有序度為400一1000林m的梯狀孔，孔隙率為80 % ~ 93 % 。The liquid phase is coupled device is the low voltage gradient itself in a high - pressure pumps add ratio valves in the atmosphere will be set according to the proportion of online several solvents mixed, then pump into the gas system
液相色譜中的低壓梯度洗脫裝置就是在高壓泵之前加上一個比例閥，在常壓下將幾種溶劑按設定的比例在線混合之後，再泵入色譜體系。There are many different methods of growth cdse single crystals, but they have some deficiencies. in our study, the technique of the purification of starting materials had been improved : the purification of polycrystalline and growth of cdse single crystals had be carried on in the same quartz ampoule and starting materials had been transferred into the growth ampoule directly in the last process of purification, which avoided the extra contamination
由於制備具有高純度和高電阻率的cdse單晶體非常困難：到目前為止，制備cdse單晶體的方法雖然很多，如溶液法、熔體法、溫度梯度溶劑區熔法（ tgsz ）等，但是都因各自的不足而沒有成為簡便而理想的制備cdse單晶體的方法，所以cdse單晶體沒有得到廣泛的應用。分享友人
