variance surface 中文意思是什麼
variance surface
解釋
方差面-
It is shown that the error could be rather remarkable in some extreme situations and could be neglected in the others. the variance of parameters inside pixel, contexture of the pixel and the surface wind speed are the controlling factors of the scaling error
結果表明亞像元狀態和結構是像元尺度誤差的主導因素，風速變化對尺度誤差有明顯的影響，不論何種形式的非均勻性，都須遵循相同的尺度擴展步驟，以達到消除誤差的目的。 -
Some normalization methods are discussed in detail, including histogram method, expectation - variance method and trend surface analysis
這里詳細介紹了各種測井數據標準化的方法原理，並給出了相應的實例。 -
However, the application of global tidal model to the study of shallow sea tides is much worse in the accuracy. tidal signal in topex / poseidon altimetric data is the largest contributor to sea surface height variability and accounts for more than 80 % of the signal variance. so it is urgent to develop tide model in the shallow area wi th high accuracy
潮汐是高度計資料海面變化中最大的成份，占總變化80以上，伴隨著衛星高度計資料在海洋研究中的廣泛應用，發展基於衛星高度計資料的高精度淺海潮汐模型成為進一步利用高度計資料研究其它物理海洋問題的基礎。 -
Results show that the interdecadal anomalies are more significant in the variance of the system anomaly in the north pacific ( np ), and the interannual and interdecadal anomalies are about equivaleut in the tropical pacific ( tp ) ; the interdecadal change characters of the surface ( shallow ) layer of the ocean and the atmosphere aloft are unanimous in the same season and region, and their transition from a low mode to a high mode both occurred from the end of 1970s to the beginning of 1980s, with an exception for july in the np, which is related to the stability of the stratification of sea temperature within the sub - surface layer ; the interannual scale air - sea anomalies are associated with enso, is most typical for january, then july in the tp, followed by january in the np, and there is no visible relationship for july in the np
在海氣系統異常的方差構成中，北太平洋區域以年代際異常為主，熱帶太平洋區域年際和年代際異常相當；表（淺）層海洋與大氣的年代際變化特徵對同一季節、區域是一致的，且20世紀70年代後期到80年代初均發生由低模態向高模態的轉變；北太平洋區域的7月與此不同，這與該季節近表層海溫層結穩定有關；年際尺度的海、氣異常與enso有關，且以熱帶太平洋區域1月最典型， 7月次之，北太平洋區域1月再次之， 7月無明顯關系。 -
Through manufacturing special pattern, using the variance analysis and range analysis of the orthogonal experiment, the effects of process parameters on prototyping size, form and position accuracy, surface roughness are discussed, the combination of process parameters are optimized, and the prototyping quality is greatly improved
通過製作專門的樣件，採用正交實驗的方差、極差分析方法，討論了各工藝參數對成型件尺寸、形位精度和表面粗糙度的影響，並且優化了工藝參數的組合，大幅度改善了成型件質量。
