Circuit experiment is a very important professional basic course for students of electrical experiments. Experiment study is further validation of theoretical study and supplement. If the deviation between the experimental data and the theoretical value is large, it will not verify the theoretical value, instead it will make students feel puzzled. So if there is a problem, how to solve it? This paper is mainly from the experiment, numerical simulation and theoretical values to compare and determine the accuracy of measuring damping coefficient method under the condition of under-damped RLC second-order circuit. It also analyzes the reasons of the error, and then put forward the damping coefficient correction method.

In the computer lab, the software system platform is composed of various applied softwares. Those softwares usually contradict when choosing and installing them because different tasks taken by the lab need different software configuration, which brings hidden troubles for the smooth and efficient operating of the software system. To solve this problem, this paper analyzes the contradiction of different applied softwares in the lab, establishes the principle of choosing and installing software according to the task and makes the install tactic.

Fundamental and definition of convolution in the course of Signal Analysis and Process was introduced. From modeling analysis to realization by Matlab software,students can be led to design an echo system by themself,using the convolution technology,which can make the students grasp the essential of convolution,impulse response and concept of system. One proposed a method to make a simulated echo system by Matlab software,taking sound signals as the excitation and response of the system. From the experiment,students can hear the echo sound from systems made by their own,which can enhance their understanding to the concept of system,improve their interests to the course,and take good effect on teaching.

PANI@ZnS quantum dots composite materials were prepared by two steps. First,ZnS quantum dots were synthesized by hydrothermal method at a constant temperature of 150℃,and then PANI@ZnS composite quantum dots were obtained with the in situ polymerization of aniline. The products were characterized by X-ray diffractometer( XRD),ultraviolet-visible spectra( UV-vis),infrared spectra( IR),Raman spectra( Raman),transmission electron microscopy( TEM). The PL patterns show that the PANI@Zn S peaks are broaden compared to the ZnS peak and exist the clearly blue shift.

The movement and fuel consumption of the No. 3 Chang'e during the landing procedure on the near moon point and remote moon point is researched as well as the trajectory design and optimal control strategy is given. Firstly,the movement trajectory is projected to a plane at the remote moon point direction. Coordinate axis is established based on the zero longitude and zero degree latitude. The movement of the No. 3 Chang'e in near moon point is considered as uniform circular motion. Then the location of near moon point and remote moon point can be calculated. Subsequently,the minimal fuel consumption is set as the target variable to compute the optimal driving force in the case of the minimal consumption.
