Abstract: This application discloses a NB-IoT-based communication method and an apparatus, to evolve a NB-IoT communication technology into an NTN. The method is as follows: A terminal device generates an uplink signal, including a superframe which includes a synchronization sequence located in first duration of the superframe and a data frame located in second duration which is after the first duration, the synchronization sequence successively includes a first sequence repeated Ni times and a second sequence repeated N2 times, the second sequence is obtained by multiplying the first sequence by ?1, a part of consecutive sequences of the synchronization sequence are used as a first synchronization reference sequence that is obtained based on the second sequence repeated N2 times and one or more first sequences that are sorted from back to front in the first sequence repeated N1 times. The terminal device sends the uplink signal to a network device.

Abstract: A non-belt automatic mechanized sampling system for a truck configured to collect materials from a carriage of the truck. The system includes an integrated sample preparation component having, in descending arrangement, a discharging mechanism and a feeder, a crusher, a constant mass dividing machine and a sample retention barrel. The system also includes a constant mass dividing machine configured to divide the crushed material into samples and discards. The samples are conveyed to a sample retention barrel and discards to a discharging mechanism, which is configured to convey the discards to the carriage.

Abstract: A solid material grinding method and device with an adjustable discharge size includes a grinding disc housing, and a movable grinding disc and a stationary grinding disc provided in a grinding disc cavity of the grinding disc housing coaxially with grinding surfaces opposite to each other. The movable grinding disc is driven to rotate in the grinding disc housing, thereby grinding materials between the movable grinding disc and the stationary grinding disc. The movable grinding disc is further connected to a pushing mechanism, and the pushing mechanism adjusts the distance between the movable grinding disc and the stationary grinding disc in a push-and-pull manner. A top rectifying blower and a side edge rectifying blower respectively blow gas from an upward side and a lateral side of the movable grinding disc and the stationary grinding disc. A central rectifying blower blows gas to the center of the stationary grinding disc.

Abstract: A fully automatic inductive sample-collecting bucket capable of storing sample information includes a bucket, and a bucket cover snap-fitted to an upper end of the bucket. A bucket cover cavity is formed in the bucket cover. A locking mechanism, and a control mechanism for driving the locking mechanism to act are integrated in the bucket cover cavity. An integrated circuit (IC) card inductive control assembly is integrated in the bucket cover. The bucket is provided with a radio frequency identification (RFID) chip. The IC card inductive control assembly is configured to identify IC card unlocking information of an external grip for cover opening work and to drive the control mechanism to work to control an action of the locking mechanism. The sample-collecting bucket integrates an RFID card capable of carrying sample coding information, and can realize the automatic cover-sealing and cover-opening function under the identification and control of the controller.

Abstract: Provided is a non-belt automatic mechanized sampling system for truck, including: a working platform including a transport channel and a slide rail extending along a first direction, the transport channel is arranged under the slide rail and makes the truck pass; a first frame configured to slide with the slide rail; a sampling mechanism (configured to collect materials from the truck along a second direction perpendicular to the first direction, the first and second directions are arranged horizontally; an integrated sample preparation component including a discharging mechanism and a feeder, a crusher, a constant mass dividing machine and a sample retention barrel. The feeder transports the material to the crusher. The crusher crushes the material and transports the crushed material to the constant mass dividing machine. The constant mass dividing machine divides the crushed material into samples to the sample retention barrel, and the discarded material to the discharging mechanism.

Abstract: Provided is a non-belt automatic mechanized sampling system for a train, including: a working platform provided with a slide rail; a sampling mechanism slidably arranged on the slide rail and configured to collect materials from the carriage of the train; an integrated sample preparation component including a discharging mechanism and a feeder, a crusher, a constant mass dividing machine and a sample retention barrel arranged from top to bottom. The feeder transports the material to the crusher. The crusher crushes the material and transports the crushed material to the constant mass dividing machine. The constant mass dividing machine divides the crushed material into samples to the sample retention barrel, and the discarded material to the discharging mechanism. The discharging mechanism transports the discarded materials to the carriage.

Abstract: Provided are apparatuses and methods for super resolution imaging photolithography. An exemplary apparatus may include an illumination light generation device configured to generate illumination light for imaging a pattern included in a mask through the mask. The illumination light may include a high-frequency spatial spectrum such that a high-frequency evanescent wave component of spatial spectrum information for the light is converted to a low-frequency evanescent wave component after being transmitted through the mask pattern. For example, the illumination light generation device may be configured to form the illumination in accordance with a high numerical aperture (NA) illumination mode and/or a surface plasmon (SP) wave illumination mode.
