求翻译：式中， 为一级衍射角；d为光栅常数；m为整数。取 ，由式（6.5.1）算出在不同光栅常数下，光栅一级衍射角与波长的关系，如图6.24所示。为了在可见光范围内获得较大的衍射角（300－600），选择 较为适宜。是什么意思？

Where  as a diffraction angle; d is the grating constant; m is an integer. Take, calculated by formula (6.5.1) in the grating constant, grating a diffraction angle and wavelength relationship, as shown in Figure 6.24. In order to get a larger diffraction angle (300-600) in the visible range, select

In a first-class,  diffraction angle; D is constant; M raster is an integer. By the, .1 (6.5 in) from constant different raster, raster-level diffraction angle and wavelength, such as the relationship shown in Figure 6.24 . In order to the visible light range for a large diffraction angle (300 - 60

In the formula,  is the level diffraction angle; d is the grating constant; m is an integer.Takes, figures out by type (6.5.1) under the different grating constant, the diffraction grating level diffraction angle and the wave length relations, as shown in Figure 6.24.In order to obtains the big dif

Type, as one level of diffraction angle; d of grating constant; m is an integer. Taken from (6.5.1) calculated under different grating constant, diffraction grating level relationship between wavelength and angle, as shown in Figure 6.24. In order for a larger angle of diffraction in the visible lig
