Abstract: This invention discloses a rare earth energy-saving admixture and its preparation method for cement kilns, involving the field of energy saving and emission reduction technology for cement kilns. The invention, without changing or minimally changing existing hardware equipment, reduces the thermal consumption of the production system and sulfur-nitrogen and sulfur emissions by conducting a thermodynamic diagnosis and calculating the amount of rare earth energy-saving admixture to be added, thereby saving the cost of retrofitting large hardware equipment.

Abstract: A protective enclosure, an energy-storage apparatus, and an electricity-consumption device are provided. The protective enclosure includes a main housing and a heat-conducting member. The main housing defines a heat-conducting hole. The heat-conducting hole extends through the main housing in a thickness direction of the main housing. The heat-conducting member is mounted at an inner side of the main housing, is integrated with the main housing, and covers the heat-conducting hole.

Abstract: A method for adjusting a state of an energy-storage battery, a terminal, and a non-transient computer-readable storage medium are provided. The method is applied to an electronic apparatus. The electronic apparatus includes a battery-state-adjustment button. The method includes the following. Touch information input by a user through the battery-state-adjustment button is received; state-adjustment information of the energy-storage battery is determined according to the touch information; state adjustment is performed on the energy-storage battery according to the state-adjustment information to obtain a target state adjusted; and the target state is displayed by a display module in the electronic apparatus.
