中文拼音 [huǎnfālìzi]
緩發粒子
英文
delayed alpha particles-
This gs case is unusual because of the disease happened after 12 years of aml remission in a patient considered to have been in remission of acute myelogenous leukemia ( aml ) for twelve years
本病例曾患急性骨髓性白血病，並經治療且疾病緩解十二年後，在子宮頸上發生顆粒性白血球肉瘤，因此更顯此病例特殊之處。The process parameters of preparing nanosized titanium dioxide powders were systematically studied by electrochemical synthesis experiments at room temperature. the rutile phase and anatase phase powders were obtained in the sizes of 9. 7nm and 9. 2nm respectively, and the complete crystal powders were formed after calcined at 400 for two hours. in the process of experiments it was observed that the low current density resulted in rutile phase powders, while the addition of little amount of ions of sulfate promoted the formation of anatase phase powders
在本實驗條件下，小的電流密度有利於金紅石相的生成，而少量硫酸根離子的引入對生成銳鈦礦相粉體有利，調整電流密度大小和引入硫酸根離子的量，可以得金紅石型和銳鈦礦型的混合混體；研究無定型粉體，銳鈦礦相粉體以及金紅石型粉體隨溫度的粒徑變化情況時發現，粉體在400以前晶粒長大相對緩慢， 400以後晶粒粗化現象嚴重。The inserting method and properties of the composite materials in consist of omt and poly ( styrene - butyl acrylate ) had been researched ; the ultra - fine organic rigid particles crosslinked polystyrene ( xps ) has been synthesized by emulsion polymerization, the effect of the synthesis process on the size of organic rigid particles was discussed. the cause of the increasing mechanical properties of pp composite materials, which were strengthened and toughened with organic rigid particles and elastomer, had been investigated. the results of studying viscosity and precipitate height of sio2 nano - particles suspension showed that the sio2 nano - particles are very good dispersed by dp270 or cat 639w dispersant
通過粘度法和沉降法測定結果的一致性，說明分散劑dp270和cat639w對sio _ 2納米粒子有較好的分散性， dp270的最佳用量為0 . 2時懸浮液粘度從35 . 1mpa ? s降為23 . 3mpa ? s ， cat639w最佳用量為0 . 4時懸浮液的粘度從35 . 1mpa ? s降為23 . 1mpa ? s ；通過研究分散劑存在下納米粒子的苯丙乳液聚合動力學，發現納米粒子的存在對乳液聚合有一定的緩聚作用，並討論了乳化體系、溫度、引發劑、表面處理劑以及納米粒子用量對聚合的影響。
