According to practical work condition, section of a three segment hoist boom is self-determined with SECWRITE commands, then a finite element model is directly established in ANSYS environment with ANSYS finite element analysis software. Using Beam44 beam unit and node degree of freedom coupling technique to simulate connecting between each boom section and conduct finite element analysis, calculated result of stress deformation for the boom is obtained. The result from digital simulation is in relative coincidence with theoretical analytic result and the nonlinear decline occurrence in boom bending moment curve is explained.

The effect of the flight on the activities of energy metabolism related enzymes in the flight muscles of the Oriental armyworm moth, Mythimna separata females was studied. These enzymes measured were glyceraldehydes-phosphate dehydrogenase, glycerol-3-phosphate dehydrogenase, lactate dehydrogenase, and 3-hydroxyacyl-CoA dehydrogenase. In the first 5 min of the tethered-flight of 3 day-old moth, activities of all the enzymes related to carbohydrate and lipid metabulistu increased rapidly, enzymes related to lipid metabolism were completely activated, and the activities of HOAD were significantly strengthened. But in flight duration from 5th to 60th min, the activities of all energy metabolism related enzymes decreased, suggesting that the flight was going to be stabilized.
