共變異數 的英文怎麼說
中文拼音 [gòngbiànyìshǔ]
共變異數
英文
covariance-
It is found that " phase produces coplanar slip and reduces the number of movable slip systems because its particles are cut by moving dislocations in deforming process, for its large critical size of cut - bypass, accordingly its strengthening contribution is anisotropic. and strengthening contribution of t1 phase is also anisotropic because it distributes on the four { 111 } slip planes while its critical size is small
研究表明,相由於顆粒的切過-繞過臨界尺寸較大,在變形過程中被運動位錯切過,由此產生共面滑移,減小可動滑移系數目,所以其強化具有各向異性; t _ 1相的臨界尺寸較小,但分佈於四個{ 111 }滑移面上,故其強化也具有各向異性。Members of the hong kong hapmap group specialising in bioinformatics and statistics also participated in the data analysis group of the hapmap project by developing software for selecting variable sites for genetic studies and for measuring the genetic relatedness between pairs of individuals. professor tsui provided some comments on this project

本文根據小波分析的基本原理,對原子鐘信號進行多解析度分解,將分解后的小波變換系數進行加權平均,得到不同小波尺度綜合原子時的加權平均小波變換系數,然後由小波變換的重構條件,反演綜合時間尺度.由於對原子鐘信號進行了小波分解,利用不同尺度的小波變換系數的小波方差進行加權平均,這樣既考慮不同原子鐘在穩定性方面的差異,又顧及同一臺原子鐘在不同小波尺度的變化特性.最後根據陜西天文臺國家授時中心的實測數據對這種方法進行了檢驗.表明這是一種全新的多解析度綜合方法,這種方法比較簡單而切實可行,它能提取各個原子鐘的共同特性,多解析度綜合時間尺度的平穩性明顯優于其他方法Adjoint function algorithms and direct collocation and nonlinear programming methods are applied to resolve the non - coplanar optimal orbit transfers problem

研究表明, 93w與ofc的界面連接是ofc與93w中w晶粒的連接以及ofc與93w中ni - fe粘接劑的連接共同作用的結果; ofc與tc _ 4連接界面的形成是由於ofc與tc _ 4之間發生反應擴散,並由此在二者接頭處生成了cu - ti金屬間化合物的中間相; tc _ 4 - al的連接與al - mb _ 2的連接則分別是其基體元素ti 、 al之間和al 、 mg之間元素互擴散的結果,另外,由於熱膨脹系數的差異,擴散焊接后在不同焊件的接頭處存在殘余熱應力並由此引起接頭的形變。The major findings of the study were as follows : ( 1 ) for the teachers ' high expectation group, the internal control group had a higher score on a self - concept test and an achievement motivation questionnaire than external control group. ( 2 ) for the teachers ' low expectation group, the internal control group scored higher on a self - concept test than the external group, but there was no significant difference between two groups on an achievement motivation questionnaire
