This paper proposes a new method for accurate determining the grooves of the PHG during manufacturing. It presents a way to obtain the straight line grooves using spherical wave and dis- cusses the accuracy of the grating spaces of the PHG. The resu- lts show that the testing accuracy of the grating space and the linearity of the grooves will be greatly improved using this met- hod.

The effects of Al content on microstructures and properties of(Ti,Al)N coatings were investigated.It is shown that there are three competitive preferred orientations in (Ti,Al)N,their diffraction intensity have different cbange tendency with increasing of Al content.The grating space of all thine orientations decrease and then increase with increasing of Al content.These can be used to explain the change of hardness of(Ti,Al)N coatings.

Using a disturbance develop method, we have obtained the formula for the small signal gain (S. S. G.) of the variable parameter Smith-Purcell effect FEL and show that the gain spectrum function factor takes the same form as the variable parameter Wiggler.On the basis of this formuls, the S.S.G. for linerly varying of grating space frequency is discussed. The resultS show that when the speed of the injected electron is within a range,lower than the initial resonance speed,a higher S.S.G. can be attained,and that in order to enhance S.S.G.for a given saturation efficiency, the changing rate of grating space frequency should be chosen properly.

利用微扰展开法导出了变参数Smith-Purcell型自由电子激光小信号增益表达式,其增益谱函数因子在形式上与变参数Wiggler情况的表达式相同。在此基础上讨论了光栅常数均匀变化时的小信号增益。结果表明:当电子入射速度低于系统初始谐振速度的某一范围时,有较高的小信号增益;在保证一定的饱和抽取效率情况下,为了提高小信号增益,应适当地选取光栅的空间频率变化率。
