Rotating shafts are arranged at the two ends of each strip-shaped blackboard unit and penetrate through supporting frames, worm wheels are arranged on the rotating shafts and engaged with worms in F-shaped beams, and an output shaft of a motor is connected with the worms through a transmission mechanism. The blackboard structure similar to a blind window is adopted, and thus available resources of the blackboard are increased.

The invention discloses a signal sending method and a terminal. The signal sending method includes: sending a synchronization signal block SSB in each time slot of a group of time slots; each time slot includes at least two SSBs, each of which The secondary synchronization signal SSS and the demodulation reference signal DMRS in the SSB are frequency division multiplexed on at least one OFDM symbol; the SSB is a combined block of the primary synchronization signal PSS, the secondary synchronization signal SSS and the physical broadcast channel PBCH. The solution of the present invention accommodates more SSBs in one Slot, thereby reducing the time occupied by beam scanning.

The invention relates to a method for extracting sodium p-toluenesulfonate from tiamulin synthesis wastewater, comprising the following steps: adjusting the pH of the tiamulin ammoniation production wastewater to 7-8, and then concentrating under reduced pressure to the original volume 75%~80%; cool down to 0~4°C, keep stirring for 1~2 hours, filter; mix the obtained filter cake with purified water, add activated carbon, heat up to 80°C, keep stirring for 30~60 minutes, then carry out hot filtration; Cool the obtained mother liquor to 2-4°C for recrystallization, and filter again to obtain sodium p-toluenesulfonate. The present invention adopts a relatively simple method to extract and recycle sodium p-toluenesulfonate, turn waste into treasure, increase available resources, and most importantly reduce waste water COD, reduce waste water treatment pressure, and reduce waste water treatment cost. Green and environmentally friendly, it has sustainable development significance for production. The COD of ammoniated wastewater treated by the present invention is reduced by 50% to 60%, and 310kg / m of sodium p-toluenesulfonate is obtained. 3 .

The invention discloses a soft spatial-frequency reuse (SSFR) method and an apparatus thereof, and a base station. The method comprises the following steps that: according to intensity of a pilot signal feedbacked by a user, an area of a cell that the user is located at is determined as well as frequency resources that are available for the user are determined; according to the frequency resources that are available for the user, corresponded transmitting powers are distributed and resource scheduling is carried out; according to a resource scheduling result, group users are selected, wherein the group users include users that use the same physical resource block (PRB) as the user uses in the same cell and a neighboring cell; a minimum interference leakage matrix is obtained according to the group users as well as under the minimum interference leakage matrix, the interference of downlink data of the user on the set user is minimum, wherein the downlink data are sent by a serving base station of the cell that the user is located at; a precoding matrix of the user is obtained according to the minimum interference leakage matrix; and on the basis of the precoding matrix, precoding is carried out on the downlink data so as to obtain precoded data. According to the embodiment of the invention, on the condition that the total throughput of a cell is not reduced, the throughput of a cell edge area (CEA) is increased.

The present application provides an information processing method, device, computer equipment, and computer-readable storage medium. The above method includes: if receiving a wake-up message for a background application in a CPU freezing state, obtaining the wake-up duration corresponding to the background application; the CPU freezing state refers to a state in which the background application is prohibited from using CPU resources ; If the time difference between the current moment and the last wake-up time of the background application is less than the wake-up duration, then the time difference between the current moment and the last wake-up time of the background application is equal to the wake-up duration wakes up the background application when. The above method aligns multiple wake-up messages to wake up the background application, reduces the number of times the background application is woken up, and improves the resource limit rate of the computer device to the background application, so as to save power consumption of the computer device and improve the availability of the foreground application. resource.

The dynamic mapping method for internal and external server networks based on DDNS and NAT comprises: setting a special-developed internal-external gateway server or router, storing DDNS service program and the correlated NAT conversion service program; registering internal server DN and IP address message on the gateway server by NNDS client; to the DNS request for internal network server, usingthe NAT program to automatic allocate a public IP address; starting the NAT conversion to return the public IP address to complete the dynamic mapping.

The invention discloses a time frequency two-dimensional hybrid media access control (MAC) layer access method. In the two-dimensional direction of a frequency domain and a time domain, multiple users can compete with an available resource together, wherein the available resource comprises each sub channel and different time slots. Conflict is avoided by adopting a withdrawal mechanism, and the users are accessed to a wireless channel to transmit data by competing with the available resource and combining a reservation mechanism. The frequency resource and the time resource are simultaneously utilized in the method, and the competition and the reservation mechanism are combined, so that the utilization rate of the system channel is improved; and the conflict is avoided, so that the throughput of the whole system is effectively improved.

The embodiment of the invention provides a method, device and system for frequency resource sharing, relates to the field of communication, and is used for improving the frequency sharing efficiency between equipment. The method comprises the steps as follows: a second base station receives first base station user information sent by first base station users; whether null space having no interference with first station users exists in the airspace of the second base station or not is determined according to the first base station user information; if the fact that null space having no interference with first station users exists in the airspace of the second base station is determined, the null space is used as a signal emission subspace of the second base station, and the second base station signals are transmitted with any transmission power less than or equal to the greatest transmission power of the second base station; if no existence of null space in the airspace of the second base station is determined, under the premise of interference and restriction on the first base station users, a signal channel subspace and the transmission power which enable the throughput of the second base station to be the most are chosen, and the second base station signals are transmitted with the chosen the transmission power in the chosen signal channel subspace.

The invention provides a method for extracting nickel and cobalt through granulating and heap-leaching laterite nickel ores. The method comprises the following steps of: firstly, breaking and screening raw ores to granulate until the ore is made into 100-mesh; secondly, granulating and curing: adding a binder and sulfuric acid solution according to a certain proportion to granulate in a disc granulator, wherein the compound binder is a mixture of sodium humate and water glass, the adding amount is 1-5% of the amount of core, the concentration of sulfuric acid is 5-10% so that the water content of the aggregate reaches 10-16%, and the granularity of the aggregate is 5-20mm; and in order to ensure that the aggregate has proper wet strength, the prepared aggregate is cured before heaping; thirdly, constructing heaps, and fourthly, spraying: spraying circularly or dropwise according to 3-20% of acid concentration and 5-80L / m<2>.h of spraying strength; and when the concentration of a nickel ion in lixivium reaches 1-3g / L and iron ion reaches 10-30g / L, taking out the acid to obtain the lixivium containing nickel and cobalt.
