This invention proposes a vocabulary proficiency testing method and system based on reading comprehension practice, including the following steps: Reading text preprocessing step: For each reading comprehension text, the server calculates the difficulty of each word w in the current text; then, it sorts the words in the text in descending order of difficulty and counts their frequency; providing test content to the user and accumulating difficult words; Vocabulary cognition level assessment step: After the user has accumulated a predetermined number of reading comprehension questions, all the difficult words encountered are averaged using their frequency percentage in the vocabulary frequency table WordFreq as a coefficient to obtain the average frequency percentage information. Then, the corresponding word ranking is found from WordFreq to determine the user's vocabulary size; English text recommendation based on vocabulary assessment step: Based on the user's vocabulary size, the server recommends corresponding vocabulary learning and reading texts, which are sent to the user's terminal via the network.

The application provides a capability verification liquid sample stability test method and related equipment, and relates to the technical field of radionuclide analysis.The method comprises the following steps: randomly drawing a preset number of to-be-processed liquid samples from a liquid sample, determining a stability test parameter, placing the to-be-processed liquid samples into corresponding test environments for processing, obtaining to-be-tested liquid samples, and the stability test parameter at least comprising a temperature.An analysis is performed according to a standard analysis method to obtain a measurement average value of a radionuclide, the measurement average value is corrected to a preset test date according to a half-life of the radionuclide to obtain a corrected average value, and a stability conclusion of the liquid sample under the stability test parameter is obtained according to the corrected average value.The method can test factors affecting the stability of the capability verification liquid sample, avoid the influence of these factors during the analysis of the activity concentration of the radionuclide, and improve the reliability of the analysis result of the activity concentration of the radionuclide.

This application discloses a question-and-answer spoken language detection method and related devices, electronic devices, and storage media. The method includes: recognizing the spoken response of a target subject to a test question to obtain a first phoneme sequence; selecting a second phoneme sequence as a target phoneme sequence based on the matching results of the first phoneme sequence with each of the second phoneme sequences; obtaining an editing operation sequence that transforms the target phoneme sequence into the first phoneme sequence, and obtaining a key identifier sequence for the target phoneme sequence; wherein the key identifier sequence contains a first identifier for each phoneme in the target phoneme sequence, and the first identifier represents whether the phoneme belongs to a keyword marked in the reference answer to which the target phoneme sequence belongs; and performing detection based on the spoken response, the target phoneme sequence, the editing operation sequence, and the key identifier sequence to obtain the spoken language detection result of the target subject. This scheme can improve the accuracy of question-and-answer spoken language detection.

The application discloses a vocabulary comprehensive ability test method and system combining spelling and pronunciation, and relates to the technical field of data processing. The method comprises the following steps: collecting spelling data, voice data and correction operation data of a user on target vocabulary; calculating bimodal mastery values of each target vocabulary based on the spelling data and the voice data, and calculating correction cost values of each target vocabulary based on the correction operation data; mapping each target vocabulary to a dynamic cognitive state matrix, and marking vocabulary with a bimodal mastery value lower than a first threshold value and a correction cost value higher than a second threshold value as high-risk vocabulary; if the bimodal mastery values of more than a preset proportion of associated vocabulary of the high-risk vocabulary decrease or the correction cost values of the associated vocabulary increase, it is determined that there is a vocabulary network instability risk formed by the high-risk vocabulary and the associated vocabulary; and generating a diagnosis report according to the dynamic cognitive state matrix and the determination result of the vocabulary network instability risk.
