The paper directed against the history and present of china silk industry, by analysing the principal contradiction of restricting industrial advance from the point of view in productive forces and production relations, and by comparing to the brasil silk inductry where its productive forces is quickly advanced, thus, author suggested that we must again construct the advantage of china silk industry, by transtforming a industrial mode, and by building a modern production and technique system in mulberry field, and by building a industry - like technique system for enterprise raise silk worm, and by firstly advancing a number new silkworm region in the cental and west district et cetea aspects
本文針對中國蠶絲產業的歷史和現狀，從生產力和生產關系的角度分析了制約產業發展的基本矛盾，並通過和近期蠶絲生產力發展較快的巴西進行比較，提出應從產業模式改造、建立現代化桑園生產技術體系和工業化養蠶技術體系、發展一批以中西部地區為主的新蠶區等方面，重新營造中國蠶絲產業的優勢。 -

Of the species, . characters of ecology, reproductive biology, genetic diversity, population genetic structure, endangering mechanisms, and sampling strategy have been studied in view of conservation biology. the results may be summarized as follows : by field investigation, we found that the localities recorded for four specimens of d. versipellis and d. pleiantha had disappeared, and most of the present populations are located in protected subforests. the distributional range of d. versipellis has also been reduced greatly, evidently, the number of present populations has decreased, the resources are reduced sharply, and the species are clearly endangered
從保育生物學的角度，對八角蓮種群生態學和生物學特性、遺傳多樣性水平和遺傳結構、瀕危機制及保育取樣策略進行了研究，結果如下：通過野外調查發現，原標本記載的一些八角蓮和六角蓮種群已難以找到，該類群目前多分佈於自然保護區外圍次生林地帶，分佈范圍明顯縮小，現存群體的規模也明顯減少，資源量貧乏，物種處于瀕危狀況。 -

We hold the view that, in one to two years ( late 2002 to 2003 ), the number of domestic wlan users will increase greatly and wlan will become the new hot spot in communication field ; the wlan terminal equipments will include laptop computer, table pc, pda and office devices such as printers and so on ; wlan card will become the necessary device for computer users ; wlan will be widely applied in high - grade resident areas and hotels
我們認為，在1 ~ 2年內（ 2002年底~ 2003年） ，國內wlan的用戶數量將迅速增加， wlan將成為新的通信熱點； wlan的終端設備范圍將涵蓋筆記本電腦、臺式電腦、 pda等設備及印表機等辦公設備， wlan無線網卡將成為筆記本電腦一族的必備裝備， wlan網路也將進一步在高價位住宅區、酒店等場合廣泛應用。 -
Finally, the relation between the field of view matching of digital binoculars and the size of field of view of binoculars and camera is analyzed theoretically. based on the analysis of the mft principal and measure method of image sensor ’ s mtf, the contact measure method using rectangle template for mtf of image sensor is created. according to the number of pixels of image sensor in one cycle of the template function, the quantitive relation between sine template and rectangle template is proposed through theoretical analysis and comparison
並利用衍射理論，從模板的形式（正弦形、矩形） 、模板與傳感器間距等幾個關鍵因素出發，進行了深入的理論探討，從理論上導出了矩形模板和正弦模板的差異、模板與圖像傳感器光敏面存在間距的情況下的光場分佈;並最終導出了間距存在下圖像傳感器調制傳遞函數值測得值與標準值之間的調整系數，利用此調整系數對實驗數據進行修正後可得到更為準確的調制傳遞函數。
