The process of wear design on chisel-edge ruling tool of diffraction gratings is very complex because of following two reasons that one is the load distribution on minute edge area when grating ruling  and the other is the anisotropic character of natural diamond. The former is the first step when wear design on chisel-edge ruling tool of diffraction grating  In order to predicate the load distribution on minute edge area of tool  this paper simulated the load distribution on minute edge area of tool by software when ruling on Aluminum-1100 with tabular data format flow stress and Aluminum-1100 with Power law flow stress respectively  and through comparative analysis determined the approximate load distribution on minute edge area of chisel-edge ruling tool that the high load mainly focused on the edge area close to the tip of ruling tool and amount to 200MPa while about to 100MPa on the face of tool.

The infrared radiation character (temperature and efficiency radiation area) of a space object is an important characteristic  we can judge the state of the object working in orbit by measuring temperature and variety. Due to lower temperature of the object and far distance between the object and the earth  the infrared radiation signal is faintness  therefore temperature and the infrared radiation character is difficult to measure. There are several methods to measure the temperature of the object in theory and each one has its applicability respectively  such as applying Wien Law to compute temperature  based on Stefan-Bolzmann law to compute temperature and utilizing multi-spectrum detector to measure temperature As a whole these methods are based on the hypothesis that the object is a Black-body or the radiance emissivity is constant. In fact  homochromatic radiance of object is not a constant but a function that changes with wavelength. Since the problem that an object whose homochromatic radiance s not a constant which results in temperature can not be computed accurately  we bring forward a method to contrast the luminance of the object at different wavelengths and deduce the relationship among homochromatic radiance and wavelength and the temperature of Black-body  from which we can compute real temperature of object. 2009 SPIE.
