查询词典 correlation

A satisfactory result was obtained,the correlation coefficient of the built model based on Leave-one-out Cross-validation were 0.990 0 and 0.986 7,respectively.This model is tested by 13C NMR chemical shift of three terpenoid compounds and the excellent result with correlation coefficients R =0.977 7 was obtained.

而C原子是组成有机化合物分子骨架的重要元素，其NMR谱包含了与该分子量子化学性质直接相关的信息[2]，因此，NMR谱被广泛应用于对有机化合物结构的鉴定[3-4]、动态过程和平衡及水溶液中蛋白质三维结构的研究(见2002年诺贝尔化学奖得主维特里希的成果)。

This thesis presents the preliminary study of the influence of sentence stress on prosodic features in Mandarin, and of the relationship between duration and pitch under different sentence stress levels. The results show that: The pitch is the most important factor which carries the sentence stress, with the increase of the sentence stress level, the peak of distribution contour of pitch moves towards high frequency area. In the case of"Stress"and"Light", two peaks are found in the distribution contour of duration, which means that the duration of some words are affected by sentence stress, but of others are not. The relationship between pitch and duration in"Normal","Stress"and"Light" are un-correlated, positive correlation and negative correlation respectively.

研究了汉语语句重音对音长和音高的影响、及音长和音高之间的相互关系，结果指出：（1）音高是汉语语句重音的基本表达手段，随着语句重音级别的提高，音高的统计分布曲线向高频方向推移；（2）在连续语流中的词被&重读&和&轻读&的情况下，音长分布出现双峰，表示它们的音长存在着受语句重音的影响和不受语句重音的影响两种情况；（3）词在&正常&、&重读&和&轻读&三种情况下，音高和音长的相互关系分别是：不相关、负相关和正相关。

The pressure drop of airflow consisting of pressure drop of the perforated plate and liquid-layer is mainly influenced by the plate dimension and bare tower velocity, with the increasing of bare tower velocity, pressure drop of the perforated plate increases. The experimental data are used to develop a correlation as follows:ΔpD＝1.04×10－82g This correlation should be used whenβ＜5％,0.299m/s＜u＜

空气流动的阻力主要由孔板阻力和液层阻力组成，孔板阻力主要受多孔板的几何尺寸及空塔速度的影响，空塔速度越大，孔板阻力越大，对实验数据进行回归分析得出的实验关联式为：ΔpD＝1.04×10－82g 公式适用范围：β＜5％，0.299m/s＜u＜

The prewashed samples and postwashed samples were analyzed by seminal fluid assay.RESULTS:(1) The positive rate of semen HBV DNA was 21.05%(12/57) with 4.7810~4copies/ml on average; the positive rate of serum HBV DNA was 81.82%(45/55 with 2.3310~7copies/ml on average. There is positive rank correlation between semen HBV DNA copies and serum HBV DNA copies;(2 There were 7 positive cases in 21 samples before washing, the 6 cases except one were positive after washing;(3) there arepositive rank correlation between viability、round cells、 abnormal morphology and semen HBV DNA copies.
