The invention relates to the technical field of electrochemical detection, and especially relates to a test method of an electrochemical sensor. The test method can be used to accurately judge whethersample introduction is correct or not during the detection of a sample to be tested by adopting the electrochemical sensor, can significantly reduce a deviation between a detection value and a real value, allows the measured value to be accurate and reliable, and effectively solves the problem of inaccurate detection of existing detection methods.

The invention provides a traditional Chinese medicine face region color portion information collection and analysis system and method. The system comprises a human face information collection module, a human face region color portion segmentation and detection module and an information processing and analysis module, wherein the human face information collection module is used for collecting human face images and outputting the collected images to the human face region color portion segmentation and detection module. The human face region color portion segmentation and detection module is used for conducting color portion segmentation on the collected human face images so that all divided regions can correspond to the corresponding organs in a traditional Chinese theory, meanwhile the image information of all the divided regions are detected, and the detection result is output to the information processing and analysis module. The information processing and analysis module is used for analyzing the result data of the human face region color portion segmentation and detection module to give out a face inspection diagnosis result. According to the traditional Chinese medicine face region color portion information collection and analysis system and method, by means of the newest face region color portion division method, all the color portions are analyzed, related data of all the color portions are obtained, the inspection diagnosis result is obtained by comparing the color portion projection areas according to the theory, and accuracy is improved.

The invention discloses a coal seam strain, seepage, displacement and jet comprehensive test device, which includes a coal heart chamber, a vibrator, an ultrasonic generator, a methane gas source, a seepage displacement gas source, a hand pump, a resistivity tester, a storage Gas tanks, air operated valves, rupture disc assemblies, release cylinders, pressure transducers, high pressure valves, desiccants, gas flow meters, strain gauge containments and strain gauges. At the same time, the present invention also provides a comprehensive test method for coal seam strain, seepage, displacement and jet flow, including equipment leak test, high-pressure gas seepage test, high-pressure gas displacement test, high-pressure gas jet test, resistivity measurement test, high-pressure strain Measurement.
