    摘要： Fluorescent test paper for detecting mercury ions is firstly prepared, the fluorescent test paper including a fluorescence development area and a standard fluorescent colorimetric card. With reference to an excited color corresponding to a reference channel in the standard colorimetric card, the color corresponding to a carbon quantum dots distribution area on the fluorescent test paper is observed to check the fluorescence detection environment during detection with the fluorescent test paper. In colorimetric detection of the content of mercury ions, the concentration of Hg2+ is detected based on an excited color, in the standard colorimetric card, that corresponds to a standard mercury ion sample and is closest to a color signal in a copper nanoclusters distribution area on the fluorescent test paper.

    摘要： The present invention relates to the technical field of identification on adulterated meat, and in particular, to a method for identifying raw meat and high-quality fake meat based on a gradual linear array change of a component. The present invention spatially characterizes changing rules of featured components in the meat with the utilization of sensitivities of the visible/near-infrared spectral signals to changes of the components in the meat and the advantage that spectral scanning can acquire optical signals of the samples spatially and consecutively, further constructs the identification model according to differences in components and spectra of a region of interest in the hyperspectral image by taking a derivative for characterizing rates of change of the featured components.

    摘要： Disclosed is a bacterial counting method, comprising the following steps, S1: preparing a polyaniline/bacterial composite film on the surface of a glassy carbon electrode by electric polymerization; S2: drawing the standard curve of the polyaniline/bacterial composite film modified electrode; and S3: determining the bacterial concentration of the bacteria solution sample to be tested according to the standard curve obtained in step S2. The method does not require the cultivation of the bacteria in the implementation process, such that same takes a short time and is easy to operate; the method uses aniline as the main reagent, and the consumption of the solution to be tested is small, such that the testing cost is low and the equipment is simple; the method has the advantages of a good repeatability and a wide detection linear range; and the method is an easy to operate, short time-consuming, and low cost bacterial counting method. The method is a bacterial counting method based on the polyaniline/bacterial composite film, and can achieve rapid and accurate detection of the bacterial thallus concentration.

    摘要： Disclosed is a method for detecting movement speed uniformity of a scanned target in a line scanning imaging process. The method comprises a first step of acquiring a scan image of a rectangular correction plate ABCD, a second step of performing data processing on a scan image A′B′C′D′ and a third step of calculating a uniformity representation value S of the movement speed of the scanned target. The uniformity of the movement speed of the scanned target can be calculated quantitatively, and the method can be used for precisely correcting a line scanning imaging system, so that high-precision image information about the scanned target is obtained, and the method can be applied to high-precision computer vision detection of the scanned target.
