Abstract: A method for determining a consistency coefficient of a power-law cement grout includes: determining a water-cement ratio of the power-law cement grout; according to engineering practice requirements, determining a time required to determine the consistency coefficient of the power-law cement grout; and obtaining the consistency coefficient of the power-law cement grout. The method is accurate and reliable, requires less calculation, etc.; and has very high practical value and popularization value in environmental protection and ecological restoration.

Abstract: An electronic device includes a chip and a circuit structure layer overlapped with the chip. The circuit structure layer includes a redistribution structure layer and an element structure layer, and the redistribution structure layer and the element structure layer are electrically connected to the chip. At least one of the redistribution structure layer and the element structure layer includes at least one opening, and in a normal direction of the electronic device, the at least one opening is overlapped with aside of the chip.

Abstract: A device for electrolyzing water includes pivots separately arranged on two ends of an insulating container, and a cylindrical cathode and a cylindrical anode are separately and respectively connected to the two pivots. The cathode and the anode are coaxial to the container and a plurality of through-holes are defined in sidewall of the anode and the cathode. A direct current (DC) source is provided to attach the two pivots so that the cathode and the anode are charged. A power source is provided to separately rotate the two pivots so as to rotate the anode and the cathode. The rotation velocity of the anode is different from that of cathode, thereby inducing a layer of dialytic film therebetween. Two input and output vents are separately and respectively defined in two ends of the container. An output vent is arranged on a side of the pivot connecting the anode so as to collect acidic electrolyzed water.
