Abstract: The present invention relates to a caterpillar track wheel with division of work between track and chain, methods for fitting unit track with flexible chain ring, methods for buffering prestress, and an open-dose type axle housing. Since a structure that each unit track is separated from a flexible chain ring is adopted, the thickness of the unit tracks does not influence the winding stress of the flexible chain ring and the unit tracks without thickness limitation can effectively disperse stress from the ground to more supporting wheels. Since the thinner flexible chain ring is only responsible for serially connecting the unit tracks and transmitting power, the winding stress and the tension change are reduced.

Abstract: Provided is a high throughput methylation detection method, particularly a combined sequence capture and bisulfite sequencing method. The method accurately and effectively analyzes the methylation status of the target area in several samples simultaneously, lowers the difficulty of probe design, enhances operation and application feasibility, and enables high throughput methylation detection of high accuracy on interested target sequences and areas in a complete genome. The method is targeted and conserves energy and time.

Abstract: A skate includes a ring-shaped wheel rim (1), in inner side of which a ring-shaped track (5) is provided and extends along the circumferential direction of the wheel rim; a wheel carrier provided in the inner side of the wheel rim; rollers (41, 42) located on the wheel carrier and rolling on the ring-shaped track (5); a pedal (3) provided on the wheel carrier. So the skate with such structure can decrease the height of the pedal, and eliminate the limit that the diameter of the wheel rim cannot be increased because of the limit of torque effected on the feet. Therefore, the diameter of the wheel rim of the skate can be much larger than the diameter of the sliding wheel of the prior skate, and thus the skate has the stronger performance of crossing the vertical wall.
