Autoradiography, light and scanning electron microscopy were applied to study the changes of morphology and synthesizing function of the injured cartilage in different intervals from 1 week to 6 months after intra-articular fracture.

High power device of magic-T is adopted with channel power combination technique principle.

The UWB impulse radar target-detection system including a power combination solid state pulse source,a UWB planar horn antenna array for transmitting and receiving,a quadrature demodulation receiver and a computer for controlling is designed,and its theory is presented.

Wide-band power combination is defined and classified in terms of channel and space,and the technical advantages are illuminated from the two aspects.
