结果表明：这几种配准测度和重叠面积的线性相关关系特别显著。

Empirical results from associate tests consist of positive correlation between entrepreneurship and technical efficiency, which implies a causal relationship combining relevant theory, and the significant contribution of entrepreneurship as a regressor, thus comfirms our emphasis on its role as a'generating factor'in market economy.

实证检验的结果表明，一方面，我国各地区技术效率的改善同当地"企业家精神"的发展存在显著的正相关关系；结合已有的"企业家精神"理论，这可以证实"企业家精神"对我国技术效率改善的推动作用；"企业家精神资本"对我国各地区经济产出的增加的确具有显著贡献，它作为市场经济条件下经济增长"发动因素"的作用应该得到重视。

"There is an interesting correlation between the ruggedness of a product and the ability to design a lighter and less material-intensive shipper for that product," says Green.

Focusing on the computational bottleneck of traditional CCA,StreamCCA introduces a low-rank approximation technique to reduce the dimensionality of product matrix resulted from sample correlation matrix and sample variance matrix,which improves computational performance efficiently on the premise of holding approximate precision.

经理论分析和实验证明，S treamCCA能够在线精确地识别两条多维数据流的相关关系，可以作为通用的预报和诊断分析工具广泛应用于数据流挖掘领域。

The rainstorm process is a complex and stochastic multi-dimensional process.A correlation exists between the maximal annual period-storm and the rainfall duration,with overlooking many factors,the parameterwill not be a constant.Since 1980s,heavy rain and flood of small basins can be calculated by auto-recording rainfall observation system,and 20-year's self-recording rainfall data can improve the calculation accuraey.

暴雨过程是一个复杂的多维随机过程，年最大时段暴雨xt，p与暴雨历时t的暴雨公式属于经验相关关系，忽略了不少影响因素，因此，公式中参数n值不会是稳定不变的。20世纪80年代以后，随着自记雨量观测应用，到目前已经有20多年的资料系列，小流域暴雨设计的计算就可以直接利用时段实测降水资料系列进行计算，设计洪水时，可根据实测雨量时段资料，计算该设计流域的n值，可提高计算精度。

It can be concluded that the periodic variation of tidal range and water level has both typical semidiurnal and diurnal and semi-monthly period of tide, and 64.8 d period of river runoff, which indicates that water level of the Zhujiang Delta is controlled by tide and river flow.

不同河段潮差及各分潮波振幅与径流量的大小具有明显的反相关关系，径流量越大，潮差越小，三水站潮差随流量以-0 0002的速度减小，网河区下游河段则减小得较慢。上游径流量越大，因克服径流的阻碍作用而消耗的能量越大，潮汐作用强度迅速减弱，各分潮潮波振幅和潮差沿程减小越快。
