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。 -
This experiment include many contents, in a word, that is summer condition experiment, winter condition experiment > summer - winter transition condition experiment and winter - summer transition condition experiment, furthermore summer condition experiment still include flux changing experiment and winter condition experiment still include thermal balance experiment this article dealt with the data of the test, calculating out energy absorbing ( energy discharging ) of buried pipe in winter condition ( summer condition ), input power of heat pump x heat exchanging of piece buried pipe length x co - efficiency performance ? op ( energy efficiency rate ? er ) and average heat exchanging coefficient ; in additiont this article compares the inlet water temperature and outlet water temperature of underground the first layer and the second layer buried pipe when heat pump was running, the results are that the heat exchanging ability of the second layer buried pipe outgos the first layer buried pipe, and heat exchanging is more stable ; and still analyse earth temperature resuming in the transition season. the results are earth temperature resume fast in the first week when the heat pump runs off
本文測試內容相當多，概括地說就是四個工況的測試，即夏季製冷工況的測試、冬季供熱工況的測試、夏?冬過渡季測試和冬?夏過渡季測試；另外在夏季工況的測試中還進行了變流量測試，在冬季工況的測試中還進行了熱平衡測試。本文對測試數據進行了處理，計算出了冬（夏）季工況埋管吸（放）熱量、熱泵空調器供熱量（製冷量） 、熱泵空調器輸入功率、埋管單位管長換熱量、供熱性能系數（製冷能效比）和平均傳熱系數等；另外，還比較了熱泵運行時地下一二層埋管進出水溫度變化情形，得出地下二層埋管換熱能力優于地下一層埋管，且換熱很穩定；並分析了過渡季地下一二層埋管溫度恢復情形，得出熱泵系統停機一周內地溫恢復特別快。 -
The beginning point of the first research direction is that we design a type of load - balancing virtual topology which is insensitive to the traffic, such plan method has been proposed whose name is vlbs ( valiant load - balancing schemem ), the disadvantage of vlbs is that it can only be applied to the homogeneous network in which each node has the same capacity, in chapter2, a more general valiant load - balancing scheme ( gvlbs ) has been proposed, the advantage of the gvlbs is that it can be used both on the homogeneous network and heterogeous network, in this chapter, we will give the detail derivation process and numerical analysis. the beginning point of the second research direction is that we first design a virtual topology for the physical topology under a specific traffic matrix, for a while, the traffic has changed, the network performence will decline. under such condition, in chpater 3, a virtual topology reconfiguration algorithm is studied which can decrease the average weighted hops
本文針對動態變化業務量情況下的wdm網路設計方法劃分為兩個主要的研究方向，第一個方向的研究出發點是可以在最初的虛拓撲設計過程中根據物理拓撲情況設計出一種虛拓撲出來，該虛拓撲是負載均衡的，在這種虛拓撲上跑的業務量矩陣特徵只要在某種范圍以內，無論它怎樣動態變化，網路都不會出現擁塞，但這種虛拓撲設計演算法vlbs的一個缺陷是它只能適用於同構網路，即每個節點所擁有的容量大小都相等，在第二章中，本文提出了一種更通用的負載均衡的光網路虛拓撲設計演算法gvlbs ，該演算法與傳統的負載均衡演算法vlbs不同之處在於vlbs演算法只能適用於同構網路而gvlbs演算法既可以適用於同構網路，又可以適用於異構網路，在本章中將給出了gvlbs演算法的的詳細推導和數值分析。
