Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

A water treatment method employing pollutant screening comprises: acquiring a sample to be tested from a water sample under test; performing two-dimensional gas chromatography analysis to obtain an intermediate analyte, wherein part of the intermediate analyte is subjected to EI ion source bombardment to generate ions, and subjected to mass spectrometry analysis to acquire a first spectrogram, and the rest is subjected to ECD detection to acquire a second spectrogram; and performing screening on the first spectrogram by means of a mass spectrometry difference technique, comparing the first spectrogram with the second spectrogram, and if a valid signal indicating iodinated organic pollutants or organic nitrile pollutants is present in a screening result, and the valid signal is also present in the second spectrogram, determining that the iodinated organic pollutants or organic nitrile pollutants are present. The method can be used to quickly and easily perform reliable screening for iodinated organic pollutants or organic nitrile pollutants, and to perform effective treatment on the identified pollutants, thereby achieving targeted removal of organic pollutants.

The purpose of the present invention is to quickly determine bacterial growth when detecting bacteria while culturing same. This disposable bacteria container is provided with an optical sensor unit which determines whether bacteria are growing in a transparent culture body having a cap, the optical sensor unit being provided with a fluorescent sensor having a fluorescent intensity that varies according to the residual amount of oxygen that remains after consumption by bacteria. Through the disposable bacteria container, bacterial growth is measured by measuring the intensity of fluorescence emitted from the optical sensor unit to the inside of the transparent culture body. Such non-contact measurement addresses the problems of inspector safety and limited space for the separate checking of cultures, the problems having arisen from using inspection devices for liquid cultures. Therefore, the disposable bacteria container has the effect of enabling the rapid real-time reading of a bacterial culture state and a positive determination for a culture.
