In trpsin tolerance assay. this virus could resist to 1 % trpsis at 37 in an hour. in acid tolerance assay, this virus was resistant to ph3. 0 and ph5. 0 at 37 in 2 hours, and the average infection litre of the virus decreased little. in heat assay, at 50, the virus was processed from 5 minutes to 150 minutes and at each condition the viral virulence reduced to some certain degree. among these conditions, when at 50 in 30 minutes. the average infection litre of this virus decreased over 2 tilre. and when al 50 in an hour, cpe of ihis virus disappeared. when time was set for an hour. but with processed in different temperature as 50 60 70, 80, the virus losl the multiplication capacity complelely. in biological assay, we selected different cell lines to cultivate this virus by laking advantage of possesional cells at that time in our laboratory. then we found that fcwf cell line was the most sensitive to dxmv and mdck was the second. with f81 cell line, after passaged for 12 times continuously with low concentration of fcs. the virus could produce cpe. however, with vero cell line. the virus could not procuce any cpe after many passages. the hemagglutination and lumadsorption reaction test proved that this virus had no any reaction to erythrocyte of pig, fowl and cavy. by neutrolizaion assay, dxmv could be identified as a kind of ccv
理化學研究表明,該病毒為rna病毒,對氯仿、乙醚
敏感;胰酶試驗中,經37 、 1小時處理的病毒,仍然能夠在貓源細胞fcwf細胞上生長,並且毒力基本保持不變;耐酸性試驗中,病毒分別在ph5 . 0和ph3 . 0經37作用2小時,毒力僅下降一個滴度;耐熱性試驗中,該病毒在恆定溫度50 ,設定不同時間,從5分鐘到150分鐘,毒力均有不同程度下降,其中, 50作用30分鐘,病毒平均滴度下降2個單位; 50 , 60分鐘, cpe消失;恆定時間1小時,設定不同溫度( 50 - 60 - 70 - 80 ) ,病毒在細胞上完全喪失增殖能力, cpe消失。生物學試驗,利用實驗室現有條件,選擇不同的細胞系對該病毒進行培養,發現該病毒對貓源細胞fcwf最
敏感; mdck細胞次
之; f81細胞經多次傳代,亦可出現cpe ;而vero細胞則不
敏感。血凝試驗表明,該病毒對豬、雞、人及豚鼠的紅細胞均無血凝性。
High accuracy kdp crystal optics is now considered as one of optics that is the most difficult to be processed for its series of disadvantageous characteristics to optics processing such as anisotropy, soft nature, easy to deliquesce, high brittleness, sensitive to temperature change, easy to crack and so on. therefore the long machining period, low percent of pass and astaticism quality has become the bottleneck of icf technology, and the surface quality control of kdp crystal processing has become the key problem to be solved in the research of icf in our country
Kdp晶體零件是目前公認的最難加工的光學零件
之一,因為kdp晶體具有各向異性、質軟、易潮解、脆性高、對溫度變化
敏感和易開裂等不利於光學加工的特點,所以加工周期長、合格率低、質量不穩定成為慣性約束聚變技術的瓶頸, kdp晶體超精密加工表面質量控制問題已經成為我國慣性約束聚變研究中亟待解決的關鍵問題。
Nano - tiopc60r, 40nm / ctm / pc = l / 80 / 100, s762. 5nm = 0. 533cm2 / u j ) ; thereby the single - layer nanoparticle tiopc / fluorinone - based azo composite photoreceptors were prepared and their photoconductive properties were briefly studied. in conclusion, two originalities can be outlined from this thesis : ( 1 ) by using 1, 4 - dioxane as disperse solvent, stable and uniform composites of tiopc, azo, hydrzone and polymer matrix were prepared, and the single - layer photoreceptors were successively fabricated with these composites, the photoreceptors showed high and wide range photosensitivity from visible to near infrared spectral regions
