This aircraft adopted the whole composite structure concept for environmental friendly through low fuel consumption due to structure weight reduction as well as for a competitive aircraft market.
Fig. 3 Compressive test under ETW condition Fig. 4 Configuration of fractured specimen after compressive test Conclusions This work is to investigate impact damage behavior and the residual compressive strength after impact damage of carbon/epoxy laminates which will be used for certification data base for the development of small scale aircraft.

When the power flow of the transmission lines is heavy, the shunt reactors become redundant equipments, resulting in problems such as greater power consumption and over reduction of the line voltage.
Examples In this section, data of an actual power system is employed to verify the influence of the controllable reactor on the net loss.

And the vibration amplitude of the lower work roll is more than the upper work roll, the simulation results is in good agreement with the tested data.
(2)The reduction of AGC vibration could significantly inhibit the level of vibration amplitude on roll system, and have achieved good results in practice.

Introduction Interest points are spatial features of the image that capture information from their neighbors, are distinctive and stable under transformations such as translation and rotation, are helpful in data reduction, and reduce the computational burden of various algorithms such as image registration by replacing an exhaustive search over the entire image domain by a probe into a concise set of highly informative points.

And at the same time,damage of structure often leads to reduction in structural stiffness, damping increases, and thus give rise to changes in structural dynamic characteristics, such as the lower-order natural frequency and mode shape changes[1-3].During the operation of hydraulic structures, partial damage may occur,and due to stress concentration, reinforcement corrosion, fatigue cracks and many other factors, damage of structures will continue to expand and increase, which leads to decline the carrying capacity of the entire structure,and even cause the destruction of the entire structure[4-5].In the hydraulic structure of the damage detection, the damage location is the key step.

The ingot was heat-treated at 1300C, in the  single phase field, for 20h, and then cold rolled to a total reduction of 30 % to promote microstructure evolution during subsequent heat treatment.
Almost the same compositions were obtained from the two methods, indicating the data are reliable.
