Abstract: A method for preparing a supercapacitor with good cycling stability uses NiO@CoMoO4/NF, an activated carbon plate, a KOH solution (6 mol/L), and polypropylene as raw materials, and is implemented through preparation of an NiO@CoMoO4/NF electrode and assembly of the supercapacitor, wherein the NiO@CoMoO4/NF is the anode of the supercapacitor, the activated carbon plate is the cathode of the supercapacitor, the KOH solution is the electrolyte, and the polypropylene is an isolation plate. The NiO@CoMoO4/NF electrode in the supercapacitor of the present disclosure treated with the ductile material can better adapt to volume changes during the charging and discharging process. After 10,000 cycles of charging and discharging, the capacity of the present disclosure has not faded and still maintains 100% of the maximum capacity, with a high specific capacitance of 79.4 F/g, an energy density of 35.7 Wh/kg, and a functional density of 899.5 W/kg.

Abstract: The disclosure provides a six-arm tunneling and anchoring machine, including: a tunneling system; a supporting system, wherein the supporting system is connected to the tunneling system, and at least part of the supporting system is able to be movably unfolded relative to the tunneling system, and when the six-arm tunneling and anchoring machine is in a supporting state, the tunneling system is lowered to touch a ground, and the supporting system is unfolded; a support working platform, wherein the support working platform is connected to the tunneling system, and at least part of the support working platform is able to be movably unfolded relative to the tunneling system. By means of the disclosure, the problems of long time and high labor intensity caused by the repeated forward and backward movement of water, electricity and air pipelines of a jumbolter in the related art are solved.

Abstract: A method for assessing encroachment at spin stand, an apparatus for carrying out the method and a disc drive configured taking into consideration results of such a method of assessment. In addition to determining encroachment at adjacent tracks, the method provides for the assessment of far track encroachment. The method thus provides a more reliable and more realistic measurement of encroachment, and may also be implemented to establish a relationship between encroachment impact and a specified track distance so as to facilitate quality control of heads in future applications.
