The changes in phase structure and Curie temperature of the Sm2Fe17 compound after nitrogen absorption were studied by using X-ray diffraction, differential thermal/thermo-gravimetric analyzer and magnetic measurement. The results of X-ray diffraction showed that the diffraction peaks of the Sm2Fe17 compound shifted toward lower angle after nitrogen absorption, and the characteristic peaks of α-Fe were observed. This showed that the unit cell of Sm2Fe17 expanded, the compound was decomposed to a certain extent and the characteristic peaks of α-Fe appeared.

通过X-射线衍射、差热－热重联用仪以及磁测量等手段，研究了Sm2Fe17化合物吸氮后的相结构及居里温度的变化行为。X-射线衍射表明，吸氮后Sm2Fe17化合物的衍射峰向小角度方向偏移，并且出现了α-Fe的衍射峰，这说明吸氮后化合物的晶胞有所膨胀，并且化合物有一定的分解，产生了α-Fe。

The effective prediction space concept is established, On the base of these, this paper deduces two representations' evaluating equation, one evaluates the prediction error and the other evaluates the prediction error in limited space. First, the error transfer characteristic among subsystems at different space locations is analyzed, and the direct transfer characteristic from discrete standard measure space to the workpiece measure space under measured in measure system is proven. Second, the error reconstruction condition and method of mapping from discrete standard measurement system to continuous standard measurespace are analyzed.
