The high gain x-y position sensitive PPAC with delay cable grouped readout,the scintillation foil time pickup detector focusing with ellipsoidal surface,the traverse field IC,the large area two dimensional position sensitive scintillatillator with PMT matrix readout,the Compton suppressed HPGe γ-ray detectors and twin longitudinal field iC are major components.

The fundamental principle and the constructional form of SAW high accuracy 15 channel delay line assembly is presented,the experimental result is also given.

An efficient algorithm of variance-time fractional delay line, which is used in changing sample rate, is proposed.

This paper propose an efficient algorithm of variance-time fractional delay line for sampling rate conversion(SRC),which implements bandlimited interpolation employed orthogonal polynomial based on minimum the energy of approximation in time domain.

Based on EQC coding,a address-changeable WOCDMA encoder/decoder and WLAN structure are designed,combined with the principle of the encoder/decoder based on optical fiber delay lines or Fiber Bragg Grating.

This algorithm adoptes a kind of logical layered-and-delayed broadcasting mode used for optimum information communicating with the purpose of improving the operation efficiency of the algorithm and avoiding local optimum.
