液體載熱劑 的英文怎麼說
中文拼音 [yètǐzǎirèjì]
液體載熱劑
英文
heat transfer liquid-
Now, studies on immunogenicity of hp vaccine mainly focus on oral administration with liquid or microparticles. whereas the vaccine solution administrated orally would be digested and decomposed by the low ph and pepsin. though microparticle is a popular form, it has a series of significant problems such as low encapsulation rate and possibility of antigen denaturation as a consequence of expose to organic solvents and high temperature
目前，國內外對幽門螺桿菌疫苗的研究僅局限在口服免疫，劑型以溶液或微球為主，眾所周知，液體疫苗口服后易受到胃內低ph及胃蛋白酶的破壞;微球雖然是疫苗載體研究的熱點，但在制備過程中應用的有機溶劑及高溫操作會破壞疫苗的完整性，降低免疫效果The ratio of isopropyl alcohol and pure water and temperature in the process of freezing are considerated in the research of the preparation of the pt / c electrocatalysts with freeze - drying method. the result shows, when we use 300ml pure water to wash the carbon ( 40mg ) in isopropyl alcohol ( 20ml ) to alter the ratio of isopropyl alcohol and pure water, we get the electrocatalysts with high catalytic activity ; the use of the liquid nitrogen ( - 196 ) to freeze the suspension ( carbon and precursor solution ) can make the pt / c electrocatalysts in high dispersion
採用300ml純水對20ml異丙醇中的40mg碳載體進行洗滌抽濾，來改變預凍液中的醇水比例，通過冷凍乾燥制備pt / c的性能較好;採用液氮對預凍液進行冷凍（預凍溫度為- 196 ）制備的pt / c催化劑性能較好;冷凍乾燥法可以有效地避免加熱乾燥過程中前軀體離子在碳載體表面的脫附和團聚，進而制備載量大、分散性好、粒徑較小的pt / c催化劑。Emulsion polymerization is a reaction system which can be characterized as a low - viscosity, good - heat - transference, and at the same time, the environment friendly. therefore, it is being widely used to prepare paints, vanishes, adhesives, rubbers and controlled drug release systems
乳液聚合因具有體系粘度低、傳熱快、環保以及分隔效應等特點，其產物已廣泛運用於塗料、油漆、粘合劑、橡膠和藥物緩釋膠囊載體等領域。
