Also, by using a novel offset architecture, as opposed to completely overlapped architecture, for the differential transmission pair, a 33% reduction of thickness is achieved in the design of a miniaturized common-mode filter with multi-layer LTCC technology. In view of increasing need of high-speed clock and data circuits to control their skew problems, a design of LTCC delay line is then conducted. To improve the waveform distortion associated with the microstrip/stripline-type meander delay line, a miniaturized high-frequency 3-D delay line with grounded guard traces is introduced. By means of 3-D structure, the 233 ps delay time, which requires extra board space amounting to a factor of 2.34 by stripline type meander delay line, can be shrunk into an EIA 1206 form factor.

Based on the actual conditions of the 5342 fully mechanized caving face of Wulan Coal Mine, the 3-D distribution of gas in the face is tested by measuring points arrangement in the stereo grid. The isograms of gas distribution of the face are drawn. Gas concentration nadir distribution curve along the working face incline direction is drawn by method of seeking function minimum points. The method of calculating gas emission components ratio of the face by means of the curve is brought forward.

The system adopts C8051F020 single chip microcomputer to realize the communication with the robot principal controller by means of serial port. With a compact structure, the performance of the system is unaffected by the installation position, so it can be assembled to other type of robots as a robot standardized component , in order to help the robot to complete the olfaction-related work.3. Inspired by the foraging strategies of animals, a strategy of odor source localization is put forward based on the animal predatory behavior. The strategy fuses the information of gas sensor, wind direction sensor and ultrasonic sensor etc. and integrates several good search algorithms such as Z-shaped search, upwind search and fuzzy neural network search and so on.

The binding of different halide anions to four strapped calix[4]pyrroles was studied by means of molecular mechanics and molecular dynamics simulations methods. The results indicate that the anion binding ability of calix[4]pyrrole-type systems could be effectively tuned by modifying the length and nature of the bridging straps. In this process, it was the most stable conformation upon anion binding due to the formation of four NH\|halide hydrogen bond, simultaneity, the difference of cavity by modifying straps adapted themselves to different halide anion.

In this thesis, we concentrate on the development in theoretical prediction and experimental synthesis of CN compounds in the recent 10 years. By means of ion beam sputtering, treating melamine at high temperature and pressure, pyrolyzing melamine and treating pyrolysis products of melamine by impulsive discharge and high-speed impact, we explore the routes to synthesize carbon nitrides. The chemical compositions, crystal structures and bonding states of the CN films and powders obtained from the experiment are studied by the use of EDX, XRD, TEM, XPS and FTIR.
