China Seismo-Electromagnetic Satellite （CSES） will be launched at the end of 2016 and the orbit is sun- synchronous and the altitude is about 500 km. The design of CSES satellite and ground segment are introduced in this paper first. And then the preliminary proposals of scientific data verification and cross-verification in CSES mission are given, which can be used to classify the payloads＇ operation state, and validate the reliability of data.

The heat conduction equation is solved in this paper under specific boundary conditions. The coefficients of the obtained distribution equation are simplified with the piecewise integral method. Then the associated model for the cylindrical thermal equipment is established. The relationship of the surface temperatures, the material properties and the inner wall state of the cylindrical thermal equipment is described in the associated model. This model is applied to the inner wall running state monitoring of the main pipe. A multi-channel distributed optical fiber temperature measurement system is designed to acquire the external surface temperatures of the main pipe. Then the associated model can be used to analyze the surface temperature data of the main pipe. The location and the physical dimension of the inner wall defect can be got. Therefore, the inner wall defect monitoring of the main pipe can be realized. The feasibility of this method is verified by experiment. This method also provides a theoretical basis for the real-time monitoring of the main pipe’s internal state.

Using special commands in TCP/IP protocol family can realize the detection of network running status, and network managers must master the command group. This program integrating network managers＇ manual network test into a 24-hour operation procedure can simply find out network faults occurring, and the fault information can be sent to the mobile phone of a network manager in the form of a short message, so that the network manager can take fast and active measures as early as possible.

The refrigerant mixture of ethanol aqueous was applied to the parallel type pulsating heat pipe （PHP）. The operation characteristics of the PHP were analyzed by means of experiment and nonlinear chaotic theory. Moreover, the relationship between the running state and attractor was described. The results indicate that starting power, stable running power and dry burning transition power are about 64.08 W, 148.68 W and 234.0 W respectively. The cycle and amplitude of PHP initially decrease and then increase with the increasing power. However, the data are well- distributed in a certain range. The running state is in agreement with the attractors, and the changing process for attrac- tors is as follows： the attractors first disperse in the whole phase space, then present mass status, and finally show band distribution.
