These results shed some new light in understanding the intergeneration transmission of human capital. First, it suggests that there is a causal relationship from parent's education to the education of sons and daughters. Second, the impact is larger at lower levels of schooling, and diminishes as schooling attainment increases for a given cycle of the formal education. Third, there appears to be a strong gender component in the intergenerational transmission mechanism.

这些结果为理解人力资本的代际传递提供了新的观点：其一，从父母的受教育程度到子女的受教育程度之间存在因果关系；其二，对于给定周期的正式教育而言，在教育水平较低时影响较大，随着教育水平的提高影响递减；其三，在代际传递机制中，存在强的性别成分。

本文提供的眼球的运动模型计算精确，稳定可靠，辅以可视化的软件，可以给眼科医生提供较准确且直观的临床指导，从而较大程度地提高眼外肌手术的准确程度。

The six cucumber materials with different low temperature tolerance were selected to be cultured in the artificial lighting incubator for 14 d under day temperature of 12 ℃,night temperature of 8 ℃,light of 8 h,light intensity of 30 μmol/(m2·s)(about 2 000 lx)and the abscisic acid,the growth hormone and the gibberellic acid(GA3) of cucumber leaves were ...

结果各黄瓜材料叶片中ABA和GA3含量均有不同程度增加，耐低温性材料越强，其增加的幅度越大，而叶片中IAA含量变化则不同，其中耐低温较强的材料增加的幅度较大，而耐低温较弱的材料有所降低，耐低温性中等的材料略有增加。内源激素含量与耐低温性的关系密切，可作为黄瓜耐低温性的间接鉴定指标之一。

Results: The CT images accurately reflected the fine structures inside the nasal cavities and sinuses, and it was discovered that in the Bactrian camel the turbinates were large and complex, the corresponding meatus were narrow, and the sinuses were large.
