This utility model discloses an explosion-proof chiller for testing new energy battery packs, relating to the field of battery pack testing technology. It includes an explosion-proof chiller body; a cylinder is fixedly connected to the inner wall of the bottom end of the explosion-proof chiller body; a test plate is fixedly connected to the top of the cylinder; a battery body is mounted on the top of the test plate; a connection socket is fixedly connected to the side end of the battery body; the battery body is placed on the test plate, and the cylinder raises the test plate and then suddenly lowers it, causing the battery body to fall onto the test plate after being suspended in mid-air, creating a bumping effect, thereby testing the battery body's anti-bumping effect. After the battery body is on the test plate, an impact ball rotates and impacts the battery body through an impact groove. A rotating cylinder causes the impact ball to rotate and impact the bottom of the battery body, generating vibration, which can test the vibration test effect of the battery body. This significantly improves the practicality and guiding significance of the test results, and helps improve the performance and safety of the battery body under complex working conditions.

The application relates to the battery technical field, in particular to a single cell expansion effect testing device. The single cell expansion effect testing device comprises a first clamping plate and a second clamping plate, the first clamping plate and the second clamping plate are clamped on the two sides of the thickness direction of a single cell, the first clamping plate is provided with first sliders slidable along a second direction on the two sides along a first direction, the second clamping plate is provided with second sliders slidable along the second direction on the two sides along the first direction, the first sliders and the second sliders on the same side are connected with fasteners, the first clamping plate and the second clamping plate clamp the cell, the state that the single cell is clamped between other two cells in a battery pack is simulated, and the position of the fastener can be adjusted according to simulation results, so that the expansion effect of the single cell in the actual use of the battery pack is effectively simulated, the effect of the equivalent battery pack is achieved, the safety and reliability of the battery are more accurately evaluated, and the test cost is effectively reduced.

This invention belongs to the field of clinical efficacy evaluation technology, specifically relating to a method and system for evaluating the efficacy of oral antisleep granules combined with acupoint application in treating insomnia of the heart-kidney disharmony type. The method includes the following steps: selecting subjects to form an observation group and a control group; the control group receiving oral zopiclone tablets; the observation group receiving the same treatment as the control group, combined with oral antisleep granules and acupoint application; observing and comparing indicators: comparing the indicators of the control group before and after treatment with those of the observation group before and after treatment to obtain the efficacy difference between the two groups. The indicators include: a Traditional Chinese Medicine (TCM) syndrome score, where a scale is used to score difficulty falling asleep, shallow sleep with easy awakening / difficulty falling back asleep after waking, early awakening, and lower back and knee weakness. The efficacy evaluation method and system of this application can evaluate the efficacy of oral antisleep granules combined with acupoint application in treating insomnia of the heart-kidney disharmony type.

The application discloses a tax evasion identification penetration testing method, comprising the following steps: simulating the behavior of a tax evasion company individual committing a crime in a transaction network to generate a graph adversarial sample that makes a tax evasion detection model fail to detect a single fake enterprise, performing local testing on the detection model, and calculating the false recognition rate; simulating the behavior of a tax evasion company gang committing a crime in a transaction network to generate a graph adversarial sample that reduces the overall detection performance of the detection model on multiple fake enterprises, performing global testing on the detection model, and calculating the performance reduction; and comprehensively evaluating the security of the model in the actual tax evasion identification scene by combining the false recognition rate of the local testing and the performance reduction of the global testing. The application realizes the evaluation of the security of the tax evasion identification method, diagnoses whether the method has a vulnerability, and thus guarantees the security of the application of the tax evasion identification method in a tax scene with high security requirements.
