This invention discloses a solid-phase thickening reactor for PETG chips, belonging to the field of polyester chip processing technology. It includes an outer cylinder with an inlet pipe and an outlet pipe installed at its top and bottom, respectively. Support legs are installed on the side of the outer cylinder. Inside the outer cylinder are a supporting cylinder and four movable inner cylinders. Connecting rings connect the supporting cylinder to the movable inner cylinders and between adjacent movable inner cylinders. This invention ensures that each chip can undergo sufficient and uniform heat exchange with the heat medium, eliminating heating "dead zones" and temperature differences in traditional equipment. Based on the synergistic effect of uniform dispersion, controllable feeding, and a three-dimensional thermal field, the raw material can undergo a thickening reaction in the reactor in an optimal state. This ensures the uniformity and thoroughness of the reaction, effectively avoiding quality problems such as chip viscosity differences and yellowing caused by uneven heating or inconsistent reaction times. Therefore, it significantly improves the final product quality, production efficiency, and batch stability of the PETG chips.

This invention discloses a hydrogen sensing probe and its fabrication method. The nanowire array of this invention provides a high specific surface area and a three-dimensional channel structure, improving the contact efficiency between the sensitive layer and hydrogen, providing a pathway for light / gas transmission, and balancing sensitivity and response / recovery kinetics. At the same time, it abandons the traditional external cavity mirror structure. The Fabry-Perot interferometer cavity formed by the second and first reflective layers enhances the round-trip interaction between light and the sensitive layer, improves the spectral drift amplitude and signal-to-noise ratio, and reduces the influence of environmental factors. Furthermore, the nanowire array is coupled with the emitted light field and / or reflected light field at the end face to form a local field enhancement effect, which is superimposed with the Fabry-Perot interferometer effect, resulting in a larger spectral shift caused by the same amount of hydrogen.

This application provides an IQ imbalance calibration method, apparatus, signal transmitter, and zero-IF transceiver. The method includes: acquiring a reference baseband signal and a radio frequency (RF) signal output by the IQ modulation channel based on the reference baseband signal, and converting the RF signal into a modulation baseband signal; reconstructing the modulation baseband signal to generate a baseband feedback signal characterizing the distortion of the IQ modulation channel; obtaining pre-distortion parameters for compensating for IQ imbalance based on the reference baseband signal and the baseband feedback signal; performing pre-distortion processing on the reference baseband signal using the pre-distortion parameters to generate a baseband pre-distortion signal; and performing imbalance calibration on the IQ modulation channel based on the baseband pre-distortion signal. Because the IQ modulation channel is calibrated, the image rejection ratio and error vector amplitude performance of the output signal can be improved, thus increasing the calibration accuracy of the IQ modulation channel.

The application relates to the technical field of coupon data management, in particular to a coupon management method and system, a storage medium and a program product. The method comprises the following steps: determining a use effective value of a user for a currently issued coupon in a current stage based on static behavior data and dynamic behavior data of the user for the currently issued coupon in the current stage; when the use effective value is lower than a preset effective threshold value, determining optimization parameters based on the static behavior data and the dynamic behavior data, and optimizing original coupon data to obtain target coupon data based on the optimization parameters; generating a coupon issuing detection condition based on the target coupon data, and performing standard detection on an actually issued coupon of the user in a next stage based on the coupon issuing detection condition, wherein the target coupon data comprises a target coupon use effective period value and a target coupon face value limit value; and when a detection result of the actually issued coupon is non-compliance, generating issuing adjustment information based on the target coupon data. The application facilitates improvement of coupon issuing accuracy.

This invention discloses a SONAR gene and its applications in regulating plant heat tolerance, nodulation, and immunity, belonging to the field of genetic engineering. The invention provides the SONAR gene with the nucleotide sequence shown in SEQ ID NO.1, and constructs soybean plants overexpressing and knocking out the SONAR gene, as well as Arabidopsis plants overexpressing the SONAR gene. Experimental results show that overexpression of the SONAR gene significantly improves the tolerance of soybean and Arabidopsis to 40℃ high-temperature stress, and effectively increases the basal expression level and transcriptional response amplitude of immune-related genes under pathogen-free conditions, inducing plant immune pre-excitation. Knocking out the SONAR gene significantly increases the number of nodules in soybean plants. This invention provides a new regulatory target for plant heat tolerance, nodulation number, and immune pre-excitation, and provides biomaterials for the cultivation of new soybean germplasm.
