set of residuals-
The elementary idea of the reference units method can be described as follows : firstly, by the setting of double series of reference units, we can control the highest and lowest land quality class of each village or town ; secondly, the class of the arable land will be get through the contrast between the arable land with the reference unit which has been selected in the same area, the difference in quality is the key factor to classify the land. the results show, 87. 6 % of the lands from i to iii distribute on alluvial and lacustrine plains, where the associated soils are mainly grey fulvo - aquic and calcareous concretions black ones. and 61. 4 % of them from iv to vi distribute on slightly rolling parts with mainly yellow - cinnamon soil developed from the diluvial and slope deposits
分等結果表明：臥龍區等的耕地中，有87 . 6分佈在沖積、湖積平原區，主要土壤類型是在河流沖積物上發育形成的灰潮土、在湖相沉積物上發育形成的砂姜黑土；等耕地中，有61 . 4分佈在壟崗區，主要土壤類型是洪坡積物上發育形成的黃褐土：而、等耕地集中分佈在丘陵區，主要土壤類型是殘坡積物上發育形成的粗骨性黃褐土，等別結果分佈總體上體現了不同地貌類型、土壤條件下耕地質量的差異。Organic compounds of chlorine such as ddt, for example, can literally be found all over the world due to atmospheric transport, even though many of these substances have long been banned in western industrialized countries, and they often remain and accumulate in parts of both terrestrial and aquatic food chains
例如有機氯，如ddt ，盡管在西方工業化國家裡早已經被禁止使用，但是由於空氣的傳播，差不多在世界各地都能發現，並且經常殘留和聚集在陸地和水生食物鏈中。The mathematic model of the ultra - thin spherical mirror is to be treated as elastic thin shell. then the predigested model, i. e., bended beam, used in qualitative analysis was proposed, and its deflection and stress formulas under the freely supported condition were set up. based on an off - axis aspherical primary mirror, the relationship of aspherical surface error ( rms ) in tangential plane with bended beam ’ s radius r, position s of concentrated load p and geometry length l of arc was analyzed
根據這一設想，本文建立了超薄鏡的數學模型?薄殼，並提出了強制力作用下超薄鏡的簡化模型?曲梁，推導了曲梁在簡支情況下受力變形的撓度公式，並結合一個實例，計算出曲梁變形后與所需非球面的面形殘差（ rms ）在子午方向與曲梁弧長l 、曲梁半徑r及集中力位置s的關系及滿足面形精度的r和s范圍，分析了弧矢方向的rms ，得出了同時滿足子午和弧矢方向面形要求的l 、 r和p 。Abstract : a new variable structure model reference adaptive control ( vs - mrac ) scheme is proposed in this paper. by transforming a relative degree one system into a first - order - like differential equation, it is shown that the spr ( strictly positive real ) assumption for reference model or its modified form ( if plant relative degree n * > 1 ) can be removed and the tracking error can converge to zero in finite time or a small residual set
文摘:提出了一種可具有非嚴格正實參考模型的變結構魯棒自適應控制方案，可去除變結構模型參考自適應控制中普遍要求參考模型為嚴格正實或當相對階大於1時參考模型經補償后為嚴格正實的假設.在此基礎上提出的變結構控制律可保證跟蹤誤差在相對階為1時于有限時間內收斂到零，而當相對階大於1時則可使跟蹤誤差收斂到一個殘差集內Major difference of f gene lies in no. 1 - no. 32 amino acid residues on n - terminal, which is the signal sequence of f protein and cut off short after the new peptide of f protein is combined with the membrane of vesicle. the sequence is not the composition of the f protein and the evolutronary force it bears is very small
氨基酸的差異主要集中在n端1 - 32殘基，該序列為f蛋白的信號序列，在f蛋白新生多肽與囊膜泡結合后不久被切下來，因此他不是功能性f蛋白的構成成分，所承受的進化強制就很小。The relationship between gdp and export of the prc ’ s province, cities, and autonomous regions is analysed in panel data set : gdp and export annul datafrom 1992 to 2004 in the prc ’ s province, cities, and autonomous regions. empiricalanalysis show that the fixed two panel model is better than other model, but exist theproblem of residual errors sequence correlation
同時利用中國內地省區市1992年至2004年的年度國內生產總值與對外出口貿易總額的面板數據做了大量實證分析，發現雙向固定效應模型比較適合此面板數據集，但是存在殘差序列相關的問題。分享友人
