A Survey of Bioinspired Jumping Robot: Takeoff, Air Posture Adjustment, and Landing Buffer.

A bioinspired jumping robot has a strong ability to overcome obstacles. It can be applied to the occasion with complex and changeable environment, such as detection of planet surface, postdisaster relief, and military reconnaissance. So the bioinspired jumping robot has broad application prospect.

[Effects of mild thermal pretreatment on anaerobic digestibility of sludge with low organic content].

The effects of mild pretreatment at temperature of 100 degrees C on the solubilization anP anaerobic digestibility of high solid sludge with low organic content were studied with the variation of heating times. Experimental results show soluble organic concentrations in supernatant increase with the prolonging of thermal pretreatment time rapidly, and slowly after 30 min. The dissolution rates of COD, protein and carbohydrate with 30 min of thermal pretreatment at 100 degrees C were 10.
