Based on how to scientifically and effectively designthe instruction , this study , combing educational psychology ' s cognitive instructional theory and constructivist instructional theory , suggests that instruction design must carry through vitrification instruction strategy , which means to open what was supposed to be the teachers ' matter in the traditional instruction theory , such as instruction object instruction preparation , instruction intention , instruction method and so on 摘要本文從如何科學、有效的對教學進行教學設計的角度出發,結合教育心理學的認知教學觀和建構主義教學觀,提出教學設計要貫穿“透明化”教學策略。

It is financial institution to more suit development of modern economy , because it characterizes own balance sheet , internal governance structures , as well as subdivision of investor and vitrification of work mechanism etc . based on the historic analysis about investment , the concept of the investment fund institution was definitely put forward 它以其特有的資產負債結構、內部治理結構,以及投資者細分和透明化運行機制等特征,成為一種更適應現代經濟發展的金融制度。在對投資基金進行歷史分析的基礎上,筆者明確地提出了投資基金制度的概念,之后運用相關的經濟學原理和金融理論,對這種新型金融制度進行了系統的學理解析。

When the time prolonged for 10 ~ 20min , the blastocysts rates declined to 47 . 62 % ~ 0 % . the results of cryopreservation of mouse 2 - cell embryos by straw and ops vitrification method in this study showed that when the 2 - cell embryos were equilibrated in efs40 at 20 for lmin ( one - step straw method ) before cryopreservation , the blastocysts rate was only 35 . 00 % . there was a significant difference ( p < 0 . 01 ) from the control ( 65 . 00 % ) 小鼠2 -細胞細管法和ops法玻璃化冷凍保存試驗表明:在20室溫條件下,用efs40平衡1min細管一步法冷凍?解凍后,經培養其囊胚發育率僅為35 . 00 ,和新鮮2 -細胞胚胎體外培養的對照組( 65 . 00 )的差異極顯著( p 0 . 01 ) 。

Cryopreservation by vitrification is a kind of biotechnology sprung up in 1980 ' s . it is superior in simple - equipment and facilitated - operation . vitrification refers to the physical process by which concentrated cryoprotectant and cells treated are totally vitrificated into a ice - free and homogenous state 玻璃化法是指受高濃度復合保護劑處理后的細胞連同保護劑本身都進入一個均一的無冰晶的玻璃化狀態,冰凍保存的細胞受到損傷較小,存活率較高。

In the 2 - step ops method , embryos were pretreated with 10 % eg + 10 % dmso for 30s before exposed to edfs30 , a vitrification solution , for 25s , then immersed in liquid nitrogen . the blastocyst rate of vitrified mouse morula after equilibration in 0 . 5mol / l sucrose for 5min was 100 % Ops二步法即胚胎預處理30s ,然后移入edfs30冷凍液中平衡25s冷凍保存,解凍后在0 . 5mol l蔗糖溶液中平衡5min ,培養后囊胚發育率為( 100 ) 。

The survival - rate of the recovered cells was tested by mtt and fda - pi . therefore , we got the preferable condition of vitrification , i . e . , the concentration of cryoprotectant is 60 % and the time of disposal is 15min . under this condition , the value of fda / pi is 46 . 43 凍融后的細胞經過mtt檢測和fda - pi雙熒光染色法檢測,獲得預處理過渡的優化條件,即60濃度的保護劑,預處理15分鐘,此時的fda pi值為46 . 43 。

A comprehensive research was conducting on the relations among its solidified behavior , vitrification point , adhesive power , impact strength and peel strength . the best solidification conditions of conducting electrostatic coating was established . 研究了導電涂層固化行為與玻璃化溫度、附著力、沖擊強度和剝離強度之間的關系,確立了導電涂料的最佳固化條件。

In our report , we selected trehalose to substitute sucrose in the cryoprotectant . the process of vitrification is under the same preferable condition . the survival - rate of the recovered cells was tested by fda - pi and cd34 + cell - count 凍融后的細胞以fda - pi雙熒光染色、流式細胞儀cd34 +計數等檢測手段,與同樣條件的60蔗糖保護劑處理的細胞相比較。

Certainly in the frames of the law and policy , this is a grey area . as china ’ s legal system deepening , especially after china ' s joining wto , vitrification of this grey areas will be necessary 在法律和政策的框架內,這是一個灰色地帶,隨著法治進程的深入,特別是中國已經加入世界貿易組織,這個灰色地帶必將陽光化。

Vitrification and encapsulation - dehydration are two new techniques and may have significant potential in the cryopreservation of some species of algae due to the limitation of the two - step freezing method 由于兩步法保存技術的局限性,玻璃化和包埋脫水法等新技術在某些藻類的種質保存中可能有較大的應用潛力。

The pottery of the bronze age comprises a continuation of the earlier cord - impressed and geometric traditions and a new type of ware , fired at a much higher temperature leading to vitrification 青銅器時代的陶器,除了保留早期繩紋和幾何印紋的傳統外,還有一種經過較高火候燒制而接近結晶的硬陶。
