查询词典 correlation

The result shows that: a positive correlation is found between the amount of application of chemical fertilizer and some factors, such as farming hours, attitude towards risks, total family incomes and the proportion of agricultural labour and non-agriculturallabour. A negative correlation is found between the amount of application of chemical fertilizer and other factors, such as farmers' educational background, their cognition of chemical fertilizer, and the channel of information.

The results showed that it was unsatisfactory for the whole samples to estimate the LAI, with the correlation coefficient being only 0.523. After the total samples were divided into four vegetation types, i.e., meadow vegetation, marsh vegetation, shrub and islanded forest, the correlation coefficients and the estimation accuracy were improved evidently. Cubic equations were found to be the best in the different forms of the regression models for retrieving the LAI of wetland vegetation by using CBERS data, with the R^2 value being 0.723, 0.588, 0.837, and 0.720, respectively.

The correlation coefficients of downy mildew and powdery mildew for BC1P1 and F2 individuals from the cross between K8 and K18 were 0.492 5 and 0.493 3, and they were 0.497 6 and 0.286 8 for the cross of K10 with K18, respectively. These four coefficients were all extremely significant too. By AFLP analysis, E25M63-103 marker was linked to some susceptible quantitative gene controlling both downy mildew and powdery mildew. The finding proved further some resistant gene of downy and powdery mildews linked to each other from molecular level.

The stereo image pair is acquired by a pair of calibrated cameras. Global disparity of foot is estimated at first. After the image pair is preprocessed automatically, using non-contact information-collecting technique and phase-correlation method, which is based on complex wavelet, surface matching with sub-pixel accuracy in the frequency domain is carried out. By taking order matching constraint, continuity constraint and correlation constraint together, 3D point cloud of foot is reconstructed and 3D model of foot is built by mosaicking point cloud at various angles automatically. After normalization, high-order moments are compared, which is useful for the subsequent shoe last design.

The major findings are:⑴During the intelligence test for the three groups of students, for half of the students or most of the students their scores on the all-including scale, the language scale and the performance scale all increased to various degrees;⑵From the analysis of the relationship between intelligence and reaction time, it is found that the result of this study confirms the existing views that there is a negative correlation between intelligence and reaction time, and the negative correlation is more evident when it is choice reaction time;⑶Different motor skills have different influences upon children with lower intelligence. Though the difference is not large, the average increasing percentages in the sample T tests for the three groups before and after the experiment show that the effect of open motor skill is the best, that of the synthetic motor skill or the open-closed is the better, and that there isn't a marked change in the closed motor skill trainees;⑷While analyzing the result of the experiment, it is found that the scores on the performance scale are higher than the scores on the language scale, especially in the open motor skill group, which tells us that the intelligence improving effect of physical training is realized to a greater extent through increasing their performance abililty.
