查询词典 correlation

After the region dividing, accumulation temperature has decreased correlation with latitude and increased correlation with altitude in most accumulation temperature region. This indicates that the latitude zonality of accumulation temperature is , to some degree, demolished when the study area dwindles. At the same time, the vertical zonality caused by microscale terrain is better revealed.

Through field observations and sampling, by referencing to other documents and information, with correlation analysis and principal component analysis as mathematical tools, we know that: the distribution of the number of birds has close relations with density of zoobenthos and ratio of water area, the correlation coefficient of the distribution and the two factors are 0.916 and 0.745, the density of zoobenthos is the most direct reflection; Vegetation types , the coverage and water level may have relations with the distribution of the kind of birds, normally, middle and large volume birds need high vegetation and high coverage as their habitats, and waterfowl like deep water as their habitats; Human activities have low impact on the the distribution of the number of birds, but the activities have relations with all the other environmental factors.

通过实地的观测、采样，并结合其他文献的资料，以相关分析和主成分分析作为数学工具，得知：鸟类的数量分布和底栖生物密度、水域面积比例有着密切关系，鸟类数量分布与两者的相关系数分别为0.916和0.745，其中，底栖生物密度是鸟类数量分布的最直接反映；植被类型、植被盖度和水位可能与鸟类的种类分布有一定关系，通常体积中、大型的鸟类需要较高的植被高度，来作为自己的栖息场所，水禽需要水位较深的区域作为自己的栖息场所；人为活动对鸟类数量分布的影响不大，但对所有自然环境因子都有一定影响。

We observed the difference of cavi in the different groups and the correlation of cavi to gender and age, moreover, we checked up the stability of cavi through counterchecking part subjects.results: there is a significant difference for cavi in the different groups, but partial correlation analysis revealed that there is no difference in the different groups controlling the age factor.

结果：cavi指标在正常人与冠心病、高血压及其他疾病的人群之间有显著差异，但采用偏相关统计方法，在控制年龄因素的情况下，正常人组与各患病组之间无显著差异；cavi检测值与性别无相关性，但与年龄呈较强的正相关；同一受检者两次检测的cavi值之差在0.3以下，前后两组数据具有强相关。

This paper amply discusses the investigation and design of conductance cross-correlation flowmeter, it includes the design of the conductance cross-correlation flow sensor, the design of the prompting source circuit, the design of the signal conditioning circuit under the well, the design of the signal incepting circuit on the floor and the design of the software.

论文详细介绍了研究开发的电导式相关流量计，包括电导式相关流量敏感器的设计、激励源电路的设计、井下信号调理电路的设计、地面信号接收电路的设计和上位机软件的设计。

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 agricultural incomes and planting areas seem to be not notable inflecting factors.

研究结果表明：户主的从农时间、风险态度、农户家庭总收入、以及劳力与非农比例情况对农户施肥量成正向相关关系；户主的教育程度、农户对于化肥的认知情况、信息渠道、施肥方式、是否施用有机肥、农户对于化肥利用率的认知以及农户对于污染认知程度等因素对农户施肥量成负向相关关系；农业收入和种植面积的影响则是不显著的。

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 result showed that correlation coefficients of disease indexes between downy mildew and powdery mildew were 0.619 8 and 0.677 2 at the seedling and mature stages respectively, which were extremely significant. 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.
