  1. The high - enzyme activity has 2 base changes, resulting in long amino acid sequence with native amylase. this inducing method resolved the problem of non - effective induction as in base analogue induction. and the method we used provide a new measure for this kind of work

    高酶活編碼區位點突變導致c -端序列變化和終止子的后移本誘變方法克服了用堿基類似物在體內誘變由於核酸復制酶等的校正作用而造成誘變無效的難題,為基因的誘變找到了一條新途經。
  2. According to elasto - plasticity theory, with the help of finite - method program ansys, the paper undertakes the computer analogue tests about the bearing capacity of pile tip arranged by orthogonal principle, and attains the relations of pile - tip bearing capacity to embedment depth, pile diameter, cohesion, internal friction angle and modulus of deformation. by the means of mathematical statistic, regression equation of the ultimate bearing capacity calculated by finite element method is gained through the regression analysis of 81 group data from the computer analogue tests. by comparison and analysis of the values calculated by finite - element regression equation and the values of in situ loading test, the regression equation is gained which calculates the size effect for base resistance of large diameter pile

    根據彈塑性理論,運用大型有限元軟體ansys按正交設計理論對樁端承載力進行模擬計算,獲得樁端承載力與樁長(埋置深度) 、樁徑、粘聚力、內摩擦角及變形模量等主要影響因素的關系,並採用數理統計方法,對81組ansys模擬試驗結果數據進行回歸分析,得到有限元法確定樁端極限承載力的回歸公式,並將有限元法回歸公式計算值與現場小壓板載荷試驗值進行比較分析,得到大直徑樁端阻的尺寸效應系數計算公式。
  3. On the base of similarity theory of fluid system, the similarity numbers are analyzed, and the similarity relationship between the original model and the analogue model is researched, and much experiment has been carried out. in order to get experiment data, a computer measure system has been developed, which is mainly made up of host computer ( pc ) and extension computer ( by scm mainly )

    本文在流體力學中流動體系的相似理論基礎上,推導了流場的相似準數,分析了各相似準數在模型中的作用,得出了原型(試驗臺)的流動狀態與實船的相似關系,並據此為理論依據在原型(試驗臺)上進行試驗研究。
  4. Rapid development of data business, growing of packet network technology, and increasing of communication channel capacity, etc, bring this problem the answer : the next generation network will be base on the ip, and it will be to consist of network architecture which are diverse, synthetic and open such as speech sound, data, multimedia etc. the principle of voip ( voice over internet protocol ) is not complicated : at the sending end, sample the analogue speech sound signal, code and compress, then package and transmit it over the packet network

    數據業務的快速發展、分組網路技術的成熟、數據網路通信通道容量的不斷增加等給這個問題提供了答案:下一代網路將是基於ip的,下一代網路將是可以提供包括語音、數據和多媒體等各種業務的、綜合的、開放的網路構架,而voip正是這個答案的具體體現。實現voip的原理並不復雜:將模擬的語音信號采樣、編碼並進行壓縮,封裝在數據網路的分組中進行傳輸,在接收端對數據進行解碼、數模轉換恢復成模擬信號即可。
