In this paper, the sine and cosine shaped sensors have been designed by using the integral characteristics of PVDF piezoelectric film. The sine PVDF sensor can be used alone to measure the displacement, speed, acceleration, stain, stress of the roof beam vibration; the cosine PVDF sensor can be used alone to measure the angular displacement and shear of the roof beam vibration; by using them jointly , the structural intensity can be measured for the roof beam without any finite differential error.

本文利用PVDF压电薄膜独特的积分特性，设计制作了正弦形状和余弦形状传感器，它们单独使用，正弦形状的PVDF传感器可以用来测量梁振动的位移、速度、加速度、应变、应力、弯矩；余弦形状的PVDF传感器可以测量振动梁的角位移和剪力；配对使用它们，可以用来测量梁的结构声强，用它们测量结构声强时不会产生有限差分误差。

For achieve two-wheel balanced function, we used fuzzy control algorithm to program the controlled codes.

A ship course controller is designed for Norrbin nonlinear ship mathematical model with matching uncertainty. Combining the backstepping algorithm with the nonlinear damping algorithm to design controller, the nonlinear damping is used to cancel the uncertainty. The integral item is introduced in the design to improve the performance of the controller. Now, general ships can only use the electric gyrocompass to measure the course angle, but they have no equipments to measure the angular velocity, so in this article another ship course controller of output feedback is designed for Norrbin nonlinear ship, firstly the angular velocity is estimated by the observer and then the ship course controller is designed.

本文基于含有匹配不确定项的Norrbin非线性船舶数学模型，将backstepping算法和非线性阻尼算法相结合设计船舶航向控制器，利用非线性阻尼来抵消系统的不确定项，同时为了更好地改善系统的性能，在设计过程中引入了积分项；由于目前一般船舶只有电罗经用于测量船舶的航向角，还没有测量船舶航向角速度的设备，因此，针对Norrbin非线性船舶模型设计了一种输出反馈控制器，首先利用观测器对船舶航向角速度进行估计，然后再设计船舶航向控制器。

To against an afterload of 1.96kPa(200mmH_2O), measure two groups of direct flow and antidromic flow, both begin with the pressure difference of 0mmH_2O, add more 20 mmH_2O every time ,measure three tines at each pressure difference, get the average value at each pressure difference.

Further, we use return on equity to measure corporate performance and the management expense ratio and the asset turnover ratio to measure agency costs.

我们构建了公司治理指数用来衡量公司治理结构，用自由现金流来衡量债券融资对经理过度消费等行为的约束，用主营业务利润率来衡量公司经营绩效，用管理费用率和资产周转率来衡量公司代理成本，结果显示公司债券融资对公司治理结构、自由现金流和公司绩效影响不显著，但与公司的代理成本为显著正相关，也就是说目前我国公司债券融资还不能发挥债权治理的功能。

Firstly, we hypothesize that the stocks of funds with net outflow will have a higher herding measure when the fund manager is concerned with his reputation risk (Scharfstein and Stein, 1990), and have a lower herding measure when he engages in gaming the incentive scheme derived from the asymmetric performance-flow relation. The results support the reputation-risk hypothesis.

首先，针对前期流量与基金群集指标的关系，本研究推论：如果经理人行为符合声誉风险假说(Scharfstein and Stein， 1990)，则前期净流出基金的群集指标会高於前期净流入基金的群集指标；反之，如果经理人行为符合放手一博假说，则净流出基金的群集指标低於净流入基金的群集指标，实证结果符合声誉风险假说。
