3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Environment The surrounding world relative to a central thing. Note. In this document, it refers specifically to the human (animal) environment and the natural environment. The human (animal) environment includes but is not limited to the oral cavity, skin, reproductive tract, intestinal tract, etc.; natural The environment includes but is not limited to air, water, soil, sediment, etc. 3.2 Relative abundance The relative proportion of a specific kind of microorganisms in the environmental microbial community. Note. Usually expressed as a percentage. 3.3 Microbial metagenomics microbialmetagenome Take the entire microbial community in a specific environment as the research object, without separation and cultivation, directly extract all the microbial genes obtained Group DNA. Note. It can be used to analyze its genetic information, species classification, system evolution, gene function and metabolic network, etc. 3.4 Qualityofbasecaling Evaluate the probability of accurate base recognition. Note. Abbreviated as Q, usually expressed as a numerical value. The base recognition quality value is negatively correlated with the base recognition error rate, and the two follow a logarithmic function relationship. Base recognition quality The higher the value, the lower the error rate. ......
