  1. Recently, as an advanced and eco - friendly method of powder preparation, freeze - drying has been developing quickly. the ultrafine ni powder with the average size of 50nm was prepared by freeze - drying form the niso4 and naoh and was studied by means of xrd, ir, fesem, tem, and dsc. the catalysis of nickel powders to nh4clo4 and how the precursor forms and the processes of the amorphous precursor to the final nickel powders are discussed

    本論文以分析純niso4 、 naoh為原料，採用冷凍乾燥技術成功的制備了50nm左右的球狀超細鎳粉，通過xrd 、 ir 、 fesem 、 tem 、 dsc等材料現代分析手段對產物進行了分析和表徵，研究了超細鎳粉對高氯酸銨熱分解的催化活性、前驅體的形成以及非晶態金屬鹽到晶態超細鎳粉的轉變過程。
  2. 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。
  3. The results indicate that drying thickness, radiant temperature and pressure of drying chamber are the most three significant factors. there ' s hardly any relationship between freezing rate and drying time, the sublimation drying time of slow freezing material is shorter than quick freezing one, but its desorption drying time is relatively longer, so the total drying time is approximately the same. the initial freezing temperature and freezing manner has little influence on vacuum freeze drying process

    試驗表明：凍干厚度、加熱板溫度、系統的真空度是最重要的三個過程參數；凍結速率對總凍干時間沒有影響，慢凍物料的升華乾燥時間要比快凍物料短，但慢凍的解析時間相對較長，兩者的總凍干時間相差很小；初始凍結溫度對凍干過程的影響可以忽略。
  4. Cadmium adsorption by lyophilized biomass of f2 was more efficient than oven dried biomass with removal ratio above 88 % in water with cadmium concentrations of 0. 96, 9. 22 and 51. 3mg / l. the adsorption process accord with stair adsorption kinetics, and initial ph value of solutions has a little effect on cadmium removal

    F2冷凍乾燥菌體對水中鎘的吸附能力遠大於烘乾菌體，鎘濃度為0 . 96mg l 、 9 . 22mg l 、 51 . 3mg l的溶液中鎘的去除率均在88以上，吸附過程符合一級吸附動力學特徵，而且受到ph的限製作用很小。
  5. The development of the heat and mass transfer during vacuum freeze drying

    真空冷凍乾燥過程傳熱傳質理論研究的動態
  6. In this paper, the principles and the main processing of new methods for preparation of ferrite powders are discussed, including self - propagating high - temperature synthesis, low - temperature combustion synthesis, mechanochemical synthesis, hydrothermal synthesis, freeze drying and supercritical fluid drying
