  1. These observations show that reprogramming is easier in interspecific embryos reconstructed with es cells than that reconstructed with somatic cells, and that es cells have the higher ability to direct the reconstructed embryo development normally than fibroblast cells. oocytes were reconstructed with outbreeding kunming albino mouse es cells and enucleated rabbit oocytes, and the effects of the passages of es cells and 6 - dmap on the development of interspecific reconstructed oocytes were analyzed. the interspecific reconstructed es - rabbit oocytes were activated either by combined two set electric pulses and 6 - dmap or by two set electric pulses

    以上結果顯示, 6 dmap能增加胚胎幹細胞異種重構卵的卵裂率,對重構卵囊胚的發育率影響不大;高培養代數和低培養代數的胚胎幹細胞用於異種核移植不影響異種重構卵的卵裂率和囊胚發育率;用胚胎幹細胞作為供核細胞;比體細胞作為供核細胞所構建的異種重構胚更容易進行重編程,並且胚胎于細胞指導異種克隆胚胎正常發育的能力強于體細胞。
  2. It was the first trial to employ the newly equipped migration data acquisition and analysis system for the scanning entomological radar and, a twin light - trap developed in china for, systematic long - term observations of migration of the beet armyworm spodoptera exigua, beet webworm loxostege sticticalis and cotton bollworm helicoverpa armigera in northern china the study provided direct evidence for the migration of 5 ". exigua in china, many parameters of migratory behaviour of the three species of insects, a better understanding of the relationship between migratory behaviour and wind or temperature field. the results enriched the theory of migration and provided new scientific knowledge for pest management in china

    本研究初步闡明了我國華北地區空中昆蟲群落結構,首次使用我國自行研製的掃描昆蟲雷達的數字化數據採集及分析系統,及價廉、高效的姊妹燈誘蟲法對華北地區甜菜夜蛾spodopteraexigua 、草地螟loxostegesticticalis和棉鈴蟲helicoverpaarmigera的遷飛進行了長期系統地觀測,得到了甜菜夜蛾在我國北方遷飛的直接證據,三種害蟲遷飛行為的若干參數,認識了昆蟲遷飛行為與風溫場的關系,豐富了昆蟲遷飛理論,為我國害蟲的治理提供了科學依據。
  3. In order to attain the proposed objectives within limited time and financial budget, this study employed the micro household economic approach which combine structured household survey with a number of intensive quantitative techniques, including direct observations, in - depth interviews and focused - group discussions

    本論文研究以微觀經濟學的方法為主,結合社會學和人口學的方法。研究主要基於微觀的農戶水平,社區和政府的描述性資料作為研究的補充。
