Distributed electrode switching device is an important part of high density resistivity instrument, and its performance will directly affect the usage of high density resistivity instrument in field work. This thesis introduces a design method of distributed electrode switching device. The device utilizes MCU to control magnetic latching relays to switch, and thus controls electrodes to switch automatically. It also utilizes RS485 chips to complete communication with adjoining electrode switching circuits. In order to test the device, this thesis introduces a software design method and the device turns out to be low power, small size and high reliable.

Based on the principle of ultrasonic transit time ranging, this article describes that the microcontroller is used as the core to develop the ultrasonic distance-measurement automobile-reversing radar control system. The system includes both hardware and software parts. The hardware part mainly consist single-chip control circuit, ultrasonic transmitting and receiving circuits, temperature compensation circuit and voice alarm circuit. The software design part of the system was divided into several function modules with modular design method, such as main program module, temperature measurement module, voice alarm module and so on. The main program was responsible for dispatching management all the modules. Experiments show that this system can reach design requirement and has high value and broad application prospects.

To avoid degradation of navigation performance in the navigation warfare environment, the multi-radio integrated navigation system can be used, in which all available radio navigation systems are integrated to back up Global Navigation Satellite System (GNSS) when the GNSS is not available. Before real-time multi-radio integrated navigation systems are deployed, time and cost can be saved when the modeling and simulation (M&S) software is used in the performance evaluation. When the multi-radio integrated navigation system M&S is comprised of independent function modules, it is easy to modify and/or to replace the function modules. In this paper, the M&S software design method was proposed for multi-radio integrated navigation systems as a GNSS backup under the navigation warfare. The M&S software in the proposed design method consists of a message broker and function modules. All the messages were transferred through the message broker in order to be exchanged between the function modules. The function modules in the M&S software were independently operated due to the message broker. A message broker-based M&S software was designed for a multi-radio integrated navigation system. In order to show the feasibility of the proposed design method, the M&S software was implemented for Global Positioning System (GPS), Korean Navigation Satellite System (KNSS), enhanced Long range navigation (eLoran), Loran-C, and Distance Measuring Equipment/Very high-frequency Omnidirectional Radio range (DME/VOR). The usefulness of the proposed design method was shown by checking the accuracy and availability of the GPS only navigation and the multi-radio integrated navigation system under the attack of jamming to GPS.

Seismic displacement design method and allowable values of story drift are compared between Chinese, American, European and Japanese seismic design codes. An engineering example's seismic displacement is calculated in the methods given by the four codes, and story drift are compared. Researches show that allowable story drift of Chinese code under rare earthquake action is approximately close to that of American with a 10% probability of exceedance in 50 years, and allowable story drift of Japanese code is more rigorous than other three codes. For three-story three-span reinforced concrete frame structure, in the condition of same intensity, displacement of Chinese under the earthquake action with 2~3% exceeding probability of 50-year is greater than that of American and European with 10% exceeding probability of 50-year. However, intensity plays no role in Japan's displacement calculation, and the calculation result of displacement of Japanese code is less than other three codes.

To fulfill the requirements of processing, analysis and inversing the observational data of experimentations, simulation software for the inversion of satellite experimentations is designed and developed independently on the developing platform of Qt, based on satellite observational data inverse theory. It provides a simulation and calculation platform for analysis and evaluation of space tests. By using dynamics principle and energy conservation principle, the software resolves inverse problems in satellite orbital dynamics. This article mainly presents the function and design method of the software, explains the design goals, shows the overall design framework, and emphasizes key technologies and countermeasures in process of the software design and realization. The software could be used to investigate the inversion of observational data and evaluate technologic indexes in satellite tests.
