Through the analysis of contest experimental test questions from 1995 to 2003, it is found that metage, synthesis, standardization and determination are the characteristics of these years " experimental test questions. chemistry experiment is based on the elementary knowledge, especially checking the usage of suction pipet and buret. the core of questions lies on the basic operation of metage, dissolution, suction, refluxing, filter, wash and titration
通過對1996 - 2003年化學競賽決賽實驗題進行分析得出: 「稱量?合成?標定?測定」是近幾年實驗試題的特點;化學實驗重在基礎,特別是考察移液管和滴定管的使用;基本操作如稱量、溶解、移液、回餾、抽濾、洗滌、滴定等是實驗考查的重點。The effects of the method repeatability, sample mass, standard titrate solution and enviroment temperature on the uncertainty of pta acid value determined with titrimetry were assessed and discussed
摘要對滴定法測定精對苯二甲酸酸值的過程中的方法重復性、樣品質量、標準滴定溶液、環境溫度等方面對不確定度影響進行了評定討論。Larval fish of cynoglossus semilaevis g unther were treated with colchicines to get the karyotype, 12 ~ 50 - day larval fish were selected to be put into the solution of colchicine of different concentration for 5 - 6 hours. the fin, and the other part of the fish were cut off to be treated with low concentration infiltration, solidify, eduction and other procedures. at last, the suspending cells can be gained and treated with air - drying method
選取孵化時間為12 50天的幼魚,在不同濃度的秋水仙素溶液中處理5 6小時,分別剪取冠狀幼鰭、鰓絲和身體周圍的鰭條,通過低滲、固定、解離,得到細胞懸液,熱片法滴片, giemsa染色。In order to get the soluble recombinant eo protein and inspect the protein expression status convinently, the egfp and eo gene were ligated into baculovirus transfer vector. with the co - transfecting sf9 cells of baculovirus recombinant transfer vector and linearized viral dna, and plaque purification in the posttransfection procedure, the pure recombinant baculovirus were harvested, which infected the sf9 cells for amplifying to generate a p - l stock. in the meantime, the fluorescence microscopy detection indicated expressed egfp protein to confirm the heterogenous protein expression of recombinant baculovirus. the pi - stock from a pure plaque was used to generate a high liter p - 2 stock, which was determined in liter as 1. 14 107pfu / ml by performing a plaque assay. when a volume of p - 2 stock infected the sf9 cells with moi 5 - 10 for expression, the strong fluorescence was obeserved on the day 3 of postinfection
此外,為了得到可溶性重組eo蛋白並便於觀察重組蛋白的表達情況,我們將egfp基因與eo基因相連插入昆蟲桿狀病毒轉移載體中,與線性桿狀病毒dna共轉染sf9細胞后通過噬斑純化得到純的重組桿狀病毒,將其感染sf9細胞制備p1種子液,同時用熒光顯微鏡觀察綠色熒光蛋白的表達情況剔除表達效果差的重組桿狀病毒。再用p1種子液感染sf9細胞制備高效價的p2種子液。通過病毒液的梯度稀釋和噬斑測定,確定p2種子液的病毒滴度達1 . 14 10 ~ 7pfu ml 。分享友人
