Some troubles emerge when we use regression estimator in such a case:in a continuous survey research,when the prior sample and the present sample are independent and they have different elements,we can not compute the regression coefficient.

作连续调查研究抽样时经常用到回归估计。如果前后两个样本相互独立，并且它们所包含的元素不同，就无法直接计算出回归系数。

Methods To evaluate relationship between HF and ANP with multi line regression method and to compare HR and BP between 121 patients with EH and 41 control persons after and before exercise.

In kick hitting, the moving forward velocity of bat is the highest when the ball was hit at the right moment, which the left elbow angle is almost 180 degrees and the right elbow angle is between 100-110 degrees. In the hitting process, the displacement of body in backward/forward direction and the resultant velocity with kick hitting are larger than those with glide hitting.

Compared with the runoff in 1959～1969, the average extents o f water reduction in riverhead gully section and hill section are maximal, namely 36.33%and 36.21%, respectively, and the one o f water reduction in sand and wind section is the least, namely 20.61%.

趋势分析结果显示，河源涧区、风沙区、丘陵区各代表流域年径流量均在1970年前后发生一致性改变，即从1970年以来开始有明显的减少趋势，平均减流幅度（与1959～1969年径流相比）以河源涧区和丘陵区最大，分别为36.33%和36.21%，风沙区最小（20.61%）。
