In past 40 years, robots have been proved necessity in nuclear crisis and daily maintenance. Especially after the Fukushima nuclear crisis, robots were used to detect irradiation dose rate and sample contaminated water inside the reactor more widely. The key for a nuclear robot was irradiation hardness of its components, especially the electrical components. We conducted a ray irradiation test for the robot controlsystem based on the previous works of the motion control subsystem. The result showed the controlsystem and communication link survived under 100 Gy, then we took an additional 300 Gy total dose test and found the value of total dose under which made system the catch is incapable. Based on the results and future work, it is possible to design a controlsystem that can survive under 100 Gy.

Command and control(abbreviated C2) is the key of integrated cooperative engagement, and directly decides the process and outcome of war. As the background of integrated engagement, in view of the analysis of several typical C2 models, based on synergetic theory and method, the definition of cooperative C2 was elaborated, and a kind of cooperative C2 model was proposed. Then, framework of the model was given, the composition and function of the model were described, and the logical structure and characteristics of the model were analyzed. This research provides a new study idea and method for C2, and it has important reference value for the design of future C2 system.

This paper mainly introduced the research on constructing Mongolian Treebank based on phrase structure grammar. Having Considered related Mongolian Treebank work and Mongolian words characteristics, we developed a Mongolian syntactic tagset. The tagsetincludes twokinds of tags. One is syntactic constituent tag and the other is grammatical relation tag. On the basis of the tagset, we developed the Mongolian Treebank auxiliary processing system. Finally, we built a Treebank that contains 3645 sentences and did an experiment on this Treebank.
