Abstract: The present disclosure provides a grating including: a first substrate including stacked first and second electrode layers each including strip-shaped electrodes with an identical width, strip-shaped electrodes in the first and second electrode layers arranged alternately; a second substrate opposite to the first substrate with a liquid crystal layer therebetween; driving modules for driving the strip-shaped electrodes to form light shading parts and light transmission parts, one light shading part and one adjacent light transmission part defining a grating unit, at least one grating unit defining a grating part, the driving modules arranged in one-to-one correspondence with the grating parts; and a control module for generating driving signals in one-to-one correspondence with the driving modules according to a distance between the human eyes and the grating, thereby changing a width of the grating unit corresponding to a crosstalk position. A 3D display device and a grating driving method are provided.

Abstract: The invention relates to a low-power microwave coring machine suitable for lunar rocks and a use method. The low-power microwave coring machine suitable for lunar rocks comprises an equipment platform, wherein the support framework front plate and the support framework rear plate are mounted on the equipment platform in a sliding manner, a rear end surface of the support framework rear plate is connected with a front end of the microwave generator mounted on the equipment platform, a rear end of the microwave generator is sequentially connected with the fixed waveguide, the rotary waveguide, the power divider and the drill drum, the high-precision slip ring structure is mounted on the drill drum, the gear ferrules are arranged on an outer wall of the rotary waveguide and an outer wall of the drill drum.

Abstract: A task resource scheduling method and apparatus, through determining priority levels of multiple tasks as well as set task deadline times, and determining a preset resource upper bound, based on task priority levels schedules the successive order of executing multiple tasks, and post-scheduling tasks satisfy a first condition, wherein, the first condition is that a time resource conflict does not exist for the tasks, the time resource conflict being that a section exists on a time series where more than one task overlaps, and the sum of the resources occupied in the section having the overlap is greater than the resource upper bound. When multiple tasks are executed according to the present example embodiment, the existing first-arriving, first-compute rule is no longer utilized, but rather scheduling is performed based on the priority levels of tasks.
