  1. 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。
  2. Under the stress of nacl lower than 100 mmol / l, the tissue structure of root had no distinct difference from the control. when the concentration of nacl was higher than 250 mmol / l, the stained color of safranine was deep but not even, and color in fibrovascular tissue and peripheral cortex cell were deeper than that around fibrovascular tissue. wild type arabidopsis thaliana and two salt - tolerance mutants were used for rapd analysis

    當nacl濃度小於100mmol l時，根組織結構與對照未表現出明顯的差異；但當nacl濃度達到250mmol l時，根組織結構對番紅染料的著色較深而且不均勻，維管組織和外圍皮層細胞著色較深，而維管組織周圍的細胞著色較淺。
  3.
