研究证明资产收益率分布的偏度水平是与投资者的决策相关的，市场摩擦因素对投资者的决策行为也有直接的影响。

Results The values of sICAM-1,sVCAM-1 and tIgE in asthmatic patients were significantly higher than those in control (P＜0.01).There were 19 positive sIgE of artemisia pollen and 12 postive sIgE of dermatophagoides pteronyssinus in 23 patients.There was linear correlation between sICAM-1 and tIgE (R-square=0.502,standard partial regression coefficient=0.097,t=2.841,P=0.021 8) with stepwise regression analysis.

结果 血清sICAM-1、sVCAM-1、tIgE水平测定哮喘组均高于对照组(P＜0.01)；血清中以户尘螨和蒿草花粉的特异性IgE含量增高为主；经多元逐步回归分析提示血清总IgE含量与sICAM-1存在线性关系，其复相关平方为0.502，标准偏回归系数为0.097，t＝2.841，P＝

There is signifi cant differences between boys and girls in 20- meters- running,standing long jump,and throwing sand bag. In jump touching we have not found gender differences. Four sport event' s fieqency distribution skewed to the left. In addition, there is relation between four sport events and age, sex, height, and weight.

20米跑、立定跳远和投掷沙包，性别间差异有显著性意义，纵跳摸高未发现性别差异；四项运动指标在频数分布中呈正偏态；另外，四项运动指标与年龄、性别、身高和体重相关。

2 0米跑、立定跳远和投掷沙包，性别间差异有显著性意义，纵跳摸高未发现性别差异；四项运动指标在频数分布中呈正偏态；另外，四项运动指标与年龄、性别、身高和体重相关。

There are may be different relationship between the optical polarization and V-band magnitude in the different samples, which may be caused by different magnetic in their synchrotron radiation field.

对不同的样本得到的偏振和光学V波段的星等之间的相关关系不同，这可能由于他们的同步辐射区域的磁场的不同引起的。

The theoretical analysis and computer simulations demonstrate that the method is an unbiased estimator and its estimation precision is superior to the sliding correlator.

理论分析和仿真实验结果表明，时延估计的频域处理方法是一种无偏估计，且其估计精度远远高于滑动相关方法。

To explain the computable of correlated noise attenuation by wavelet analysis; to give adaptive wavelet shrinkage algorithm on basis of threshold. We discuss three thresholds'choice; namely eigenvalue, unbiased risk estimator and hitograph method. We give comesponding experiments'analysis and comparison. It shows that our method is reliable.

阐述了小波分析去相关噪声的可行性；给出了基于阀值的自适应小波收缩法，讨论了三种阀值的选取；论述了特征值法，无偏的风险估计与直方图法，给出了相应的实验分析与比较，说明了该方法是可行的。

With longger perianth segment and Liriodendron tulipiferawith widder perianth segment. The length of fruit ahd number of little key fruits showed patroclinal transgressive inheritance, so Liriodendron interspecific hybrids with bigger fruit could be selected by Liriodendron tulipifera?

聚合果长度和聚合果具翅小坚果数表现为偏父超亲遗传，选用聚合果较长和聚合果具翅小坚果数目较多的的北美鹅掌楸作父本，有望选育出大果的杂交鹅掌楸个体，而且这两者呈显著正相关(r=0.888)。

The results showed that soil electrical conductivity had obviously spatial variability,and semi-variance and Moran's I coefficient analysis accordantly illuminated that the spatial correlation range was large and the relativity was strong on 30 April,29 June and 16 November;while the spatial correlation range was small and the relativity was weak on 20 April,14 July and 16 August.

结果表明：土壤电导率具有明显的空间变异性，半方差函数和Moran's Ⅰ系数分析说明了4月30日、6月29日和11月16日的空间自相关范围较大，相关性较强；4月20日、7月14日和8月16日的变程偏小，空间相关性较弱。

The split between the two groups can hardly be papered over.
