Research on cophasing optimized algorithms for space-based telescope segmented primary mirror;

The operating principle of interface circuit is analyzed and discussed,and the horizontal sync-phase adjustment circuit is designed and studied in de- tail.

Amplitude and phase adjustment units are important parts in ground wave OTH-radar transmitter,implementing conversion and adjustment of HF detection signal.

This paper introduces the frequency multiplication(the MLT04 Four-Channels、Four-Quadrant Analogy Multiplier) circuits and the phase adjustment circuits in the data processor with the Photoelectrical rotary encoder.

Y→△transformation is conventionally used by CT secondary current phase adjusting of transformer differential protection while its sensitivity of single phase to earth fault is lower than that of three phase fault and interphase fault.

In order to depict the depositional system of Qinan sag of Huanghua depression more accurately,seismic sedimentological studies were carried out through using three key technologies including phase shift,frequency division and stratal slicing.

Therefore we carried out seismic sedimentological studies in Qikou Sag of Huanghua Depression using two techniques,that is,phase shift and stratal slicing.
