The abandoned-son is a worldly cultural motif. In Chinese antediluvian period, the cultural phenomenon that following filial piety while being abandoned is formed by the people’s activities presented by Xiaoji, Yijiu, Boqi, and Shensheng. In the later ages, people gave more cultural meanings to such simple and plain historic phenomenon. And more cultural details were produced. By analyzing the evolution process of Boqi’s story, this paper did some academic generalization and exploration on the modle gerneration of such cultural phenomenon, inorder to provide some enlightment for the reseach on the orgin of human culture.

In auto motive applications, effective and affordable acquirement of drive shaft torque value could greatly ben-efit the vehicle drive line feedback control. This paper presents a model-based to rque observer to estimate the drive shaft to rqueusing transmission output shaft angular speed and driven wheel angular speed. A detailed drive line model used for characterizing the behavior of the HEV drive line and a simplified model used for observer design will be constructd. The estimated to rque will be used for carrying out brake system feedback control in a HEV. Several simulations will be presented to demonstrate the effectiveness of the proposed observer.

To study the cylinder motion characteristics, cylinder and shaft sleeve stress characteristics of cylinder stroke and return process influenced by different shaft sleeve structure, the cylinders with non-chamfering shaft sleeve, C0.3 chamfering shaft sleeve and R0.3 round corner shaft sleeve were used for simulation of cylinder stroke and return process. The results show that the piston velocity curves of three kinds of shaft sleeve are identical. Maximum stress of different shaft sleeves fluctuates and maximum stress elements of C0.3 and R0.3 shaft sleeve are similar. When cylinder strokes, maximum stress of cylinder occurs at the end of piston rod connected to the load; the stress of C0.3 shaft sleeve is the lowest. When cylinder returns, maximum stress of cylinder occurs at the shaft sleeve; the stress of C0.3 and R0.3 shaft sleeve differ little and are both lower than that of non-chamfering shaft sleeve. It provides a reference for structure optimization and service life improvement of the cylinder shaft sleeve.
