查询词典 sensing

The method had not only strong invisibility, but also little influence on the use of remote sensing image.

During the past long period, much progress has been realized on the study of the retrieval of LST based on remote sensing, and many algorithms for the LST retrieval have been developed. However, in these algorithms non-isothermal mixed-pixels are all treated as an isothermal and homogeneous surface, which caused directly the results that the LST obtained by these algorithms is only an average temperature of mixed-pixel.

在过去很长一段时间里，地表温度的遥感反演取得了长足的进展，发展了大量的反演算法，但是这些算法都把普遍存在的非同温混合像元视为同温同质体，直接导致反演所得的只是物理意义模糊不清的混合像元的平均温度。

In this paper, based on piezoelectric ceramic, composite and experimental mechanics theories, a kind of 1-3 orthogonal anisotropic PCM sensor is developed, and the sensing principle is analyzed to describe sensor behaviors. In order to determine strain and stress on isotropic or orthogonal anisotropic component surface, the relationships between strain and stress are established. The experimental research on 1-3 OAPCM sensor is carried out in uniaxial and biaxial stress states.

The thesis contains five chapters. The first chapter summarizes the development and research of switched reluctance drive, discusses the main research direction, and explains the main work in this paper. In chapter 2, hardware system which includes the design of power converter and various control circuit is discussed. TMS320LF2407 DSP is used to design the hardware circuits of SRM control system, and design details including the current detection, position sensing, fault protection, speed detecting, keyboard and display etc. are provided. Because of the full use of the abundant peripheral resources of DSP, it comes to the aim simplifying the circuit structure and heightening the reliability. In chapter 3, the application of neural network on SRM control system is introduced, a new the application of neural network and the method of sampling is proposed and a simulation system based on Matlab/Simulink is established. Chapter 4 discusses the routine designing issue. Because the modularized programming method is adopted, and multi-interrupt processing technique is used, operation efficiency of the control software is highly raised. At last, the foregoing SRM control system is tested. Speed adjustment is realized, and other targets on the research and design of SRM control system are reached, which establishes a good foundation for further research.
