slit source

The spectral switch effect, which is physically attributed to the diffraction by the slits and spatial coherence of light, increases with increasing slit parameter ε and source spatial correlation Δ.

缝的衍射和光的空间相干性是产生光谱开关的物理原因，增大缝参量ε和源的空间相关度Δ光谱开关效应越显著。

X-ray diodes and Dante spectrometer were used to measure X-ray flux and radiation temperature in the slit, the source and the transport end, respectively.

用XRD和Dante谱仪分别得到缝口、源和输运末端X光辐射总量和辐射温度。

According to fraunhofer single slit diffraction, the paper has discussed the influence of time coherence and spatial coherence of light source in diffraction field, the relation between the diffraction fringe and the source coherence are obtained.

以夫琅和费单缝衍射为例，讨论了光源的时间相干性和空间相干性对衍射场的影响，从而得到光源的相干性与衍射条纹清晰度的关系。

When the slit of light source there is definite width W, the width of diffraction fringe should increase, and the minimum resolving angle Δθ k should be increasing, then the resolving power of actual grating system should be decreasing.

当光源狭缝还有一定宽度W时，衍射条纹将增宽，相应最小分辨角Δθk将增大，实际光栅系统的分辨本领将减小。

The model of slit type cracking test for finite element analysis is established by HYPERMESH, the composite function of welding heating source and induction heating source is defined by FORTRAN program.

在有限元分析过程中，以斜Y坡口冷裂纹拘束试验为分析对象，利用HYPERMESH建立了有限元分析模型，采用FORTRAN语言编程实现了电弧热源和感应加热热源的复合作用。
