In order to realize missile real-time change flight trajectory  three-loop autopilot is setting up. The structure characteristics  autopilot model  and control parameters design method were researched. Firstly  this paper introduced the 11th order three-loop autopilot model. With the principle of systems reduce model order  the 5th order model was deduced. On that basis  open-loop frequency characteristic and closed-loop frequency characteristic were analyzed. The variables of velocity ratio  dynamic pressure ratio and elevator efficiency ratio were leading to correct system nonlinear. And then autopilot gains design method were induced. System flight simulations were done  and result shows that autopilot gains played a good job in the flight trajectory  autopilot satisfied the flight index. 2012 IEEE.

As a result of comparative study on human visual and Free Space Optical (FSO) communication  a new concept of satellites laser interconnect was proposed based on human bionics. For the laser link is difficult to set up directly  a new concept was given out based on the three processes of human visual capturing the objectives: voice assisting to guide  eyes' wide Field Of View (FOV) cursory capturing and eyes' foveal FOV high-resolution imaging. Three similar processes were introduced to spaceborne laser interconnect which were radio assisting to guide  beacons laser wide FOV capturing and communication laser narrow FOV capturing  so that the difficulty of setting up the optical communication link was reduced evidently. Meanwhile  the antenna optical system based on the bionics was given out. Each laser terminal configured two independent optical antenna  through the spaceborne storage and time-domain link switching  complex topology network could be set up. The simulation system was built using Virtual Reality Toolbox  the result showed that the laser terminal could search and set up communication links  which took about only lOOms from capturing the beacon to setting up communication. 2009 IEEE.

The work on laser varicose treatment carried out in CIOMP  It provides minimal invasion  CAS cooperating with The First Clinical Hospital  often under local anesthesia and intravenous sedation thereby eliminating the need for general anesthesia  Jilin University is summarized. Dozens of animal experiments adopting dog and rabbit samples are made in a long time of several years. Different lasers are used  greatly shortens postoperative recovery term  including long pulse frequency-doubled Nd:YAG(532nm) and semiconductor laser(808nm). Dozens of animal experiments show that laser has good efficacy to occlude the vein vessels. It has precise adjustability and relatively short treatment time only needing outpatient office setting with high cost and effect rate  and it is highly safe with no side effects and no serious complications.
