The invention discloses a method for obtaining spatial distribution of desert riparian forests based on GIS buffer analysis, and belongs to the technical field of vegetation remote sensing monitoring in arid regions. It includes the following steps: Step 1: Download the TM remote sensing image of the river in the arid area, perform image preprocessing, remote sensing interpretation, and NDVI calculation on it, and obtain the NDVI remote sensing data of the desert riparian forest; Step 2: Extract the river bank boundary vector line, and remote sensing The images are uniformly registered and corrected under the GIS platform; Step 3: Generate multiple buffer vector maps around the river according to the research requirements; Step 4: Overlay the multiple buffer vector maps with the NDVI remote sensing data of the desert riparian forest, and extract each The mean value of NDVI in the buffer zone, with the vertical channel distance as the independent variable and the mean NDVI as the dependent variable, was used to analyze the horizontal spatial distribution structure of desert riparian forest by curve fitting. The invention provides a beneficial reference for determining the spatial continuous gradient distribution of the desert riparian forest and its protection range.

The invention discloses a method and system for testing the power semiconductor module chip welding technology, a method and system for testing the power semiconductor module aluminum wire bonding technology, and a method and system for testing the packaging technology comprising the chip welding technology and the aluminum wire bonding technology. According to the method and system, an electric heating device is used for simulating working conditions, the impulse voltage / current is applied to the electric heating device, and / or the loop testing voltage / current is applied to heat a tested piece after chip welding, or the working voltage / current and / or the loop testing voltage / current are / is applied to a tested piece after aluminum wire bonding, and a heat infrared imager is adopted to conduct temperature field distribution testing on the tested piece. Whether the chip welding technology and / or the aluminum wire bonding technology have / has defects or not is determined according to the fact whether the temperature field distribution condition of the tested piece or an aluminum wire bonding point of the tested piece is abnormal or not. Dynamic monitoring on the chip welding technology and / or the aluminum wire bonding technology under actual working conditions is achieved, and the testing cost is reduced.

The invention provides a tire condition monitoring method based on learning type multiple perception. In this method, the minimum mileage of one or more vehicles is used as the analysis unit, and the data collected from the vehicle bus are corrected and accumulated separately for the ABS pulse data of the coaxial tires according to the errata values ​​obtained in the learning mode; if this process If there is an abnormality in the sum of the ABS pulse data of the diagonal tires, use replacement or filling to ensure the integrity of the monitoring cycle; the individual accumulated data of the ABS pulse data of the 4 tires obtained in the learning mode after correcting the errata value is used as the comparison object. The real-time tire pressure values ​​of 4 tires are the reference, and the precise tire pressure value of the next cycle is calculated by looking up the table; the early warning and alarm quantification processing of tire health status; data output, status display and sound and light alarm processing. The invention also provides a tire monitoring device. The method can monitor various tire information, and the user can obtain comprehensive tire status information.

The invention relates to an expandable miniature gastroscope robot with a telescopic arm, which can be planted. , a mechanical arm, a reverse-folding balloon support, a forward-folding balloon support, and a probe; the camera is arranged on the side of the probe, and several lighting devices are distributed around the camera; the wireless induction coil is arranged around the electronic chip; The groove is arranged on the periphery of the robot main body; the mechanical arm is arranged in the groove. Its advantages are as follows: on the one hand, it can fill the stomach volume after being opened by remote control, produce a feeling of satiety, and reduce the patient's food intake, and is used for patients who need subtotal gastrectomy due to diabetes; on the other hand, it can monitor the state of gastric mucosa for a long time 1. While regularly taking gastric mucosal tissue biopsy, it can assist in the treatment of gastric ulcer, pyloric stone obstruction and other diseases, and also has the auxiliary effect of dieting and losing weight.
