Thirty cadaveric femurs were randomly allocated into five groups, each with 6 femurs. An osteotomy was made (Pauwels angle 70°) in the middle of the femoral neck. Then each group was fixed using one of these methods:①Dynamic Hip Screw ;②Three 4mm Steinn Pins that placed in accordance with the compressive trabeculae and clingy to the femoral calcar ;③One compressive screw;④Low angle fixation of external fixator;⑤High angle fixation of external fixator.

This article introduces the development and the evolution of IT channel in our country, focusing on the IT channel pattern based on the electronic commerce. Analysis from transformation of value chain explains electronic commerce the fundamental reason which affects the IT channel. Various analyses which IT channel is affected by electronic commerce have been carried out. The relationship between the consumer network purchase behavior and the IT electronic channel has been explained, and necessity of the middle man electronic commercialized pattern had been discovered. Standing on the previous research, this article summarizes the tendency of IT channel development and predicts the future of orientation of IT channel so as to provide some principles for medium and small sized channel members. In the last part of the article, it visualizes the future new IT channel pattern from the angle of economics.

This technique uses a spiral phase plate with a small central aperture placed on the Fourier plane of so imaging system. If the spiral phase filter is rotated by a certain angle around its central axis, a phase shift between the zero-order spatial frequency component and the remaining of the object is produced, and the magnitude of this phase shift is proportional to the rotation angle. Using this property, we can record a sequence of intensity distribution of the output beams corresponding to different rotation angles, and then digitally reconstruct the objects by using a phase-shifting algorithm. Both the theoretical analysis and simulation experiment results demonstrate the feasibility of this approach.
