Abstract: The present invention provides a method for analyzing the non-observed effect concentration (NOEC) of a chemical on an organism. The analysis method includes the following steps: 1) conducting a chronic toxicity test on a test organism with a test chemical at different concentrations, and conducting assays to obtain several sets of endpoint effect data; 2) classifying the several sets of endpoint effect data obtained in step 1); and 3) constructing hypothesis testing models with the data classified in step 2), and according to the statistical significance values from hypothesis testing models, among the same set of endpoint effect data, adopting the highest concentration of the test chemical that do not produce a significant effect as NOEC within the set; and among the different sets of endpoint effect data, adopting NOEC of the set with the smallest NOEC value as NOEC of the test chemical on the test organism.

Abstract: A design method of a spectrometer and a spectrometer are disclosed, including the following steps: 1) determining an incident angle of a second incident slit and a groove-shaped cycle of a concave grating; 2) estimating a blaze angle of the concave grating, determining a surface material and a groove-shaped structure of the concave grating; 3) acquiring wavelength-diffraction efficiency curves; 4) determining values of incident angles ?A1 and ?A3 and values of wavelengths ?2 and ?3, and setting ?4 to equal ?2; 5) acquiring a record structural parameter and a use structural parameter; 6) determining a manufacture parameter of the concave grating; 7) determining locations of the three incident slits and the three photodetectors relative to the concave grating. The spectrometer acquired by using this method has relatively high diffraction efficiency in most spectrum regions and effectively alleviates the problem of relatively low diffraction efficiency in a broad spectrum region.

Abstract: The invention provides an exposure method of a holographic grating and an exposure light path. The exposure method includes: (1) determining initial positions (C, D) of the two exposure light sources (S1, S2); (2) calculating imaging quality parameters of the grating; (3) setting a compensating mirror (A1) in the initial light path; (4) adjusting a position of the exposure light source (S1) to a new position (D1) according to a position of the compensating mirror (A1); (5) calculating imaging quality parameters of the grating; (6) judging whether the imaging quality parameters in the step (5) and the imaging quality parameters in the step (2) are equal, and if yes, using the new position (D1) as a final position of the exposure light source (S1). The exposure method and exposure light path may effectively solve a problem of a much too close distance between exposure light sources.
