Methods In this section, we mainly introduce data preprocessing and classification algorithms based on heart rate threshold of hatching eggs heartbeat signal. We design a time domain algorithm for classifying hatching egg heartbeat signals, the concrete steps are as follows: • Input heartbeat signal sequence ( )x n , the length is 500. •	cache/american_scientific_journal-4711.pdf	txt/american_scientific_journal-4711.txt
