This is especially the case after China's economic growth unexpectedly slowed to 9.6% in Q2 after a 9.8% rise in Q1, undershooting estimates of a 10.5% rise.

上周美元兑日元下跌150点日元，值得日本官方注意，尤其是在中国2季度经济增长从1季度的9.8%降至9.6%，低于10.5%的预期的背景下。

Following, a experiment has been carried out, the incident waves with a frequency band of 200kHz-3 50kHz are used to the experiment, and a series of peak value-time curves are drawn each 10kHz, corresponding time are found through fitting peak value, thus the position of the defect is calculated accurately. The application of awl-shaped sensor head in the heat change water pipe experiment indicates that the ultrasonic guided waves may transmit nearly 50 meters in the pipe, which is not influenced by the elbows and makes it possible to test defects in long distance and large-scale. The water-load pipe experiment indicates that the displace and energy maybe leakage at the near-surface, which is significant for the further research.

而后，采用200kHz至350kHz频段的入射波进行了实验验证，并每隔10kHz绘出一条峰值一时间的曲线，通过拟合峰值点，找到对应的时间，从而准确的计算出了缺陷的所在；应用锥形探头的热交换水管的实验表明，超声导波可以在管道中传播了近50米的距离，且不受弯头的影响，从而使得长范围、大规模检测成为可能，水载管实验说明了离面位移和能量可能会发生泄漏的特性，为导波的深入研究和应用作了铺垫。

This paper presents a nonlinear robust adaptive excitation control design procedure for multi machine power systems using back-stepping method. The control objective is to drive machine power angle and frequency to the steady-state operation point, and guarantee that the close-loop system is adaptive to the uncertainties of generator damping coefficient and d-axis reactance, and robust to model errors or bounded disturbances.

利用反步法设计了多机电力系统中的非线性鲁棒自适应励磁控制方案，控制目标是调节发电机功角和频率至稳态运行点的极小领域，并使闭环系统对发电机阻尼系数和电抗参数的不确定性具有自适应能力，且对模型误差和外部有界干扰具备鲁棒性，同时保证各控制器是分散化和本地化的。
