球粒凝膠 的英文怎麼說
中文拼音 [qiúlìníngjiāo]
球粒凝膠
英文
spherogel-
But in the forepassed research, the people all abstracted the colloid in the water as the sphericity and explained it by the known theory of the colloid chemistry. moreover some people modified the result by the grain coefficient in the derivation of theory. but this assume had more difference on the observed phenomena in the experiment, so it was not perfect in theoretical speaking
關于絮凝的理論基礎在國外研究得比較多，但在過去的研究中，人們大都是將水中的膠體顆粒抽象為球形，用已有的膠體化學理論去加以解釋，並在理論推導中引入顆粒系數加以修正，這與實際實驗所觀察到的現象有較大的差別，從理論上說，是很不完善的。With the reference of many relevant materials, the author prepared a fined molybdenum disulfide powder with a average size of 800nm by ball milling, and a nano - copper with average size of 30nm in micromulsion solution method, and synthesized surface - modified titanium dioxide nanoparticles with average size of 40nm in organic media via sol - gel method. the tribological performances of three particles were studied by universal test as well, with the result of fined molybdenum disulfide powder with good reducing wear and antiwear performance at low load, nano - copper with good reducing wear and antiwear performance at high load, surface - modified titanium dioxide nanoparticles maintaining stable reducing wear and antiwear performance from low load to high load due to its characteristics of organic and inorganic nanocomposite. the results indicate that the nanocomposite is the most perspective oil additive. the reducing wear and antiwear mechanism of nano oil additive was studied with in - situ tribochemical principle. nano additives possess broadly developing prospect with its above - mentioned performance
在參閱了大量文獻的基礎上，分別採用了球磨法、微乳液法、溶膠?凝膠法制備了超細二硫化鉬、納米銅粒子、表面修飾納米二氧化鈦，經原子力顯微鏡測試，獲得的超細二硫化鉬的粒度平均在800nm以內，納米銅粒子平均粒度約為30nm ，表面修飾納米二氧化鈦平均粒度約為40nm ，在萬能摩擦磨損試驗機上測試了三種粒子的摩擦學特性，結果表明：在合理的添加濃度范圍內，超細二硫化鉬在低載時具有優良的減摩抗磨性能，納米銅在高載時具有比較好的減摩抗磨性能，表面修飾二氧化鈦粒子因具有有機與無機復合物的特性，從低載到高載都保持穩定的減摩抗磨性能。As for the change of reaction temperature, a good appearance of microspheres will be observed. after heat treatment we obtain the mesoporous sio2 microspheres, the morphology, size and size distribution of microspheres before and after sintering were investigated by using the scanning electron microscopy ( sem ). the desorption of water and ethanol and decompostion of polymers in microspheres were analyzed by using tg - dsc machine
當r 1時將導致微球產生破裂，而r 4時則生成凝膠狀物質；其他條件不變時，微球形貌隨ph值的增大逐漸變差，最終破裂；乙醇含量增大時，微球粒徑逐漸增大；而隨著反應時間的進行，顆粒逐漸長大，微球形貌不斷完善，表面逐漸平滑；反應溫度的變化會得到更光滑的微球表面，微球粒徑隨之增大。Results show that the empty and porous balls of tio2 were grown on the surface of fine tourmaline particles dispersing in the tio2 film based on the copper net, under the effect of the nature electric field of fine tourmaline particles
用溶膠?凝膠技術在紫銅網表面成功生長電氣石tio _ 2復合薄膜，該復合膜中電氣石微粒表面形成了tio _ 2空心球簇結構和tio _ 2層狀微粒簇結構。The samples were characterized contrastively by sem, tem, saed, positron annihilate and the different mechanism for two methods were preliminarily discussed. the experimental results showed that nano - cuo prepared by sol - gel method was spherical, which was agglomerated badly and can aging easily. however, nano - cuo prepared by pressure - hydrothermal method has loose and thin - piece appearance structure
結果表明，溶膠-凝膠法制得的氧化銅粉末呈類球形，團聚嚴重，易老化；而壓力-熱液法制得的氧化銅具有疏鬆的、薄片狀的外觀結構，粒子厚度約為20nm ，分散性較好、抗老化能力強；壓力-熱液法制備的氧化銅比溶膠-凝膠法制備的氧化銅缺陷濃度小。The sols is bright yellow and stable during a month and a half. silver sols are charaterized by a transmission electron microscopy ( tem ) and ultraviolet - visible spectrophotometer ( uv ). the result indicates that the silver particles are approximately spherical and monodispersed with an average diameter of ca. 15nm
溶膠呈亮黃色，貯存一個半月不發生凝聚，並用紫外分光光度計和透射電子顯微鏡對其研究，發現制得的納米ag為球狀粒子，粒徑為15nm 。Nano - si embedded sio2 composite thin film were fabricated by using ball - milling and sol - gel technology, it is found that the red pl band located at about 730nm is affected by the interface characteristic of nano - si, this indicated that the red emitting resulted from nc - si is also rely on its interface characteristic
