Notice some corners much and much, will have already concealed to see a point to test you to probe an ability, a very divertive game. find out 12 kind things in the room first, there are more difficult several kinds to seek. bring about a pillow, the blind side that click the bedside and mattress contain one section battery, another a the section battery is also nearby in the bed, turning on a television, there is one personal dancing, he will point out a place finally, there is the star number manifestation, notice and wait film to broadcast to finish to click again 3 times, the safe - deposit box would appear
多多注意一些角落，會有隱藏視點考考你的偵察能力，非常好玩的一個游戲.先在房間里找到12樣東西，有幾樣比較難找.把枕頭掀起，點擊床頭和床墊的縫隙處有一節電池，另外一節電池也在床附近，打開電視，有一個人跳舞，最後他會指出一個地方，有星號顯示，注意要等影片播放完再點擊3次，保險箱才會出現！ -

In view of the birth of plant tissue culture research institutions in all parts of the country in succession and tissue culture industry investment upsurge in recent years, this paper superficially analysed the application prospects and limitations of the woody plant tissue culture technique in the scientific research and production from the aspects of woody plant tissue culture technique characteristics, present industrialization situation, existing problems and solutions, etc., which provides the references for developing the test - tube fast - propagation technique and studies in the commercial application field in our country better, predicting the benefit of popularization and application of woody plant tissue culture technique in the forestry production as well as avoiding the blind investment risk
摘要針對近年來全國各地植物組培研究機構的相繼誕生和組培產業投資熱潮，從木本植物組培技術特點、產業化現狀、存在的問題及解決的方法等方面，淺析木本植物組織培養技術在科研與生產中的應用前景與局限，為廣大科技工作者更好地發展我國試管快繁技術和商業應用領域的研究，客觀正確預測木本植物組培技術在林業生產中推廣應用的效益及避免盲目投資風險提供參考。 -
Carry on a large amount of experiment and analysings, the result of calculation of designing has been verified, the error of designing and computing has been revised, the physical dimension of the rivet has been confirmed finally. combine the real working condition of the factory the difficulties that the rivet stem and the locking collar are difficult to process are solved, a series of feasible technology schemes are made finally. according to the designing and of the test of the blind rivet, consult the relevant standards of u. s. a., the relevant aviation industrial standards which lay the foundation for the popularizaion and application of the rivet are compiled
本文通過系統分析及計算，突破了鉚釘抽鉚成形、剪斷環及時被剪斷、芯桿到位及時拉斷等一系列技術難點，確定了設計方案，運用有限元方法對機械鎖緊鼓包型抽芯鉚釘進行了強度分析：制定了試驗方案，驗證了設計計算結果，修正了設計計算所造成的誤差，確定了鉚釘的結構尺寸；結合工廠的實際生產條件，解決了釘桿和鎖圈難以加工的困難，制定出?系列可行的工藝方案：根據設計及試驗結果，參照美國的相關標準，編制了系列航空工業標準，為機械鎖緊鼓包型抽芯鉚釘的推廣應用打下了基礎。 -
The main contents of this thesis include : ( 1 ) summarize and analysis of the theories on vibration transmission through rolling element bearings ( 2 ) based on the threshold setting and signal ’ s statistical approach, a method for solving the problems of denoise was developed ( 3 ) using sparsity and clustering, the method and hypotheses for underdetermined blind source separation was studied ( 4 ) the method based on potential function clustering was given for underdetermined blind source separation of noisy signals based on the assumption that the input distribution is sparse and the mixture procedure is linear, the attenuation matrix and the delay matrix were estimated by clustering. the approach was experimentally illustrated for the case of m = 2. the separation of the signals from bearing test bed proved that the given methods are available and reliable
在需求分析和研究現狀分析的基礎上，本論文針對如下內容進行了重點研究: （ 1 ）以滾動軸承為例，對旋轉機械振動信號的傳輸進行了歸納分析; （ 2 ）通過設定某一門限並研究信號間的統計特性，研究了旋轉機械振動信號的盲源分離過程中噪聲消減策略; （ 3 ）應用稀疏信號分析和聚類分析方法，對盲源分離中欠確定問題的假設條件進行探討並對分離方法進行了分析; （ 4 ）採用基於勢函數聚類分析的方法，研究了欠確定前提下含噪聲測量過程中信號盲源分離方法。
