  1. On the basis of foreign documents, the dissertation firstly describes the morphology, taxonomy, and biological characters of cochineal insects. then, by using artificial climate cases in the lab, according to orthogonal design, 8 lands of combinations of temperature, humidity and light is set, while the temperature has four levels : 15, 20, 25 and 30, and the relative humidity has two levels : 60 % and 80 %, while the light also has two levels : 980 lux and 60 lux. through observations and analysis of hatching percentage, survival percentage of the first instar and during from the second instar to the adult, the population tendency index, generation life cycle, size and eggs of female adult, the development of the cochineal under different conditions is studied

    在收集、整理國外對胭脂蟲的研究資料基礎上，首先從胭脂蟲的形態學、分類學、生物學特性入手，進而在實驗室內利用人工氣候箱，應用正交設計方法，設計了4種溫度、 2種濕度、 2種光照梯度的不同組合，通過測定胭脂蟲的孵化率、 1齡若蟲的存活率、 2齡若蟲至成蟲期存活率、種群趨勢指數、世代歷期、雌成蟲的大小、懷卵量等生物學指標，深入研究胭脂蟲在這些組合下的生長發育狀況，應用數理統計方法，分析出溫度、濕度和光照對各項生物學指標的影響，找出胭脂蟲適宜的室內培育條件，並為野外胭脂蟲的培育提供一定的理論依據。
  2. The results indicate that incubation adjustmellt is an adaptation to favor hatching synchrony, which in turn balances the growth of nestlings and increases their survival rate

    推測，孵化調節的適應意義在於促進雛鳥的同步出殼，平衡雛鳥間的生長發育，提高其成活率。
  3. " i hlrough the comparisorl of the breedi11g process, their clt1tch size was differcnt significamly, hl ) wevef, the number of the nestlings ; 1nd survivals, the incubation rate and survival rate were not different significantly between two species

    通過對白鷺和池鷺的繁殖過程比較，兩種鷺的窩卵數存在顯著差異，具有種的特異性。但兩種鷺的窩雛數、出雛數、孵化率和成活率均差異不顯著。
  4. This incubation adjustment of parents makes the synchrony in hatching and the hatching intervals of nestlings shorter than the laying intervals of eggs. this phenomenon was perhaps resulted from the incubating behavior difference of parents in laying time and incubating time. the research also found that the growth rate and survival rate in the latest hatched nestlings in little egret were lower than the earlier hatched ones

    卵的孵化時間與產卵順序呈負相關性，先產的卵比后產的卵所需孵化時間相對較長，此現象產生是由於親鳥在產卵期和產卵后的孵化行為不一致造成的，這種孵化調節使同一窩雛鳥孵出時間具有相對集中的趨勢，雛鳥出殼的時間間隔比產卵的時間間隔短；另一方面，在白鷺雛鳥的生長過程中，最晚出殼的雛鳥生長水平和成活率明顯落後于早出殼的雛鳥，而池鷺由於窩卵數和窩雛數為5的數量相對較少，雛鳥生長均衡。
  5. The contrast experiment shows that the combination of yuanji treatment and traditional chinese and western medicines exerts an obvious effect in preventing and curing gonorrhea of young shrimps, in increasing the disease - resisting ability, the survival rate, and the growth vitality, in shortening the hatching and growing period, and in improving the production of young shrimps

    通過對比試驗表明，元極處理結合中西藥物對防治羅氏沼蝦「白濁病」有明顯效果，能提高蝦苗抗病力、成活率和生長活力，縮短雌蝦孵出幼體及幼體發育成蝦苗的時間，促進蝦苗增產。
  6. This provides the research with theory basis. secondly, this thesis establishes target system to evaluate international competitive power in service trade and apply this system to adjust the service trade competitive power of our country ; then analyzes the influence on service trade competitive power according to michael porter ’ s theory on national competition superiority and carries on the relevance analysis on various factors. at last, according to the analysis results, make out the strategy to improve international competitive power in service trade such as : cultivate high and specialized elements and promote the accumulation of personnel capital ; take domestic service demand seriously and impel urbanization construction ; enhance the utilization efficiency of foreign capital, and optimize the quality of resource endowment ; strengthen the supports from related industries ; encourage service enterprise to innovate and improve their competition ability ; reinforce the government ' s hatching function and so on

    本文首先闡述了服務貿易競爭力的相關理論，並說明了競爭力理論在服務貿易中的應用，這為本文的研究提供了理論依據;其次建立了測評我國服務貿易國際競爭力的指標體系，並運用該指標體系對我國服務貿易競爭力進行了評價及國際比較;然後根據邁克爾?波特的國家競爭優勢理論分析了影響服務貿易競爭力的各因素，對各因素與服務貿易出口進行了相關性分析;最後根據回歸分析的結論提出提升我國服務貿易國際競爭力策略:大力培育高等、專業要素，促進人力資本積累;重視國內的服務需求，推進城市化建設;提高外資的利用效率，優化資源稟賦質量;加強服務貿易相關產業的協調與支持;鼓勵服務企業創新，提高競爭能力;強化政府的孵化和輔助作用等。
  7. Some interest has been generated in studying the rationale for assisted hatching. some reports suggest that embryos with lower zona pellucida thickness ( zpt ) and higher zona pellucida thickness variation ( zptv ) had a better chance of successful hatching and so the patient become pregnant ; another reports suggest that in vivo aging ; in vitro culture and exposure to ultralow temperature may induce zona hardening and then impair the embryo ability of hatching

    有作者提出胚胎透明帶厚度（ zonapellucidathickness ， zpt ）小的胚胎孵出時阻力減小，而透明帶厚度變化率（ zonapellucidathicknessvariation ， zptv ）高的胚胎由於透明帶上有一個明顯薄的區域而使胚胎易於孵出；還有作者推測病人年齡、體外培養天數的增加及冷凍處理會增加透明帶的硬度，使胚胎孵出困難。
  8. The eggs were put in an incubator filled with sand collected from their birthplace and kept at 28 to 30 degrees celsius. after two months of incubation, 85 of the 121 eggs collected hatched out baby turtles, giving a hatching rate of over 70 per cent.
