We revisit the γ-ray emission above 300 Me V towards the massive star-forming region of Orion B by adopting14 yr observations with the Fermi Large Area Telescope and utilizing the updated software *** extended γ-ray emission region around Orion B is resolved into two components(region Ⅰ and region Ⅱ).The γ-ray spectrum of region I agrees with the predicted γ-ray spectrum assuming the cosmic ray(CR)density is the same as that of Alpha Magnetic Spectrometer(AMS-02)measured ***γ-ray emissivity of region II appears to be deficit at low energy band(Eng we find that CR densities exhibit a significant deficit below 20 Ge V,which may be caused by a slow diffusion inside the dense *** is probably caused by an increased magnetic field whose strength increases with the gas density.

为了分析不同倒角尺度对压缩机气动性能及疲劳寿命的影响,首先在控制离心叶轮主要结构参数不变的前提下,通过调整叶片根部及顶部倒角尺度得到一系列设计模型,其次通过数值模拟方法对不同设计模型的离心压缩机整级进行全三维稳态模拟并在设计转速下对离心叶轮进行强度计算,最后联合估算法及材料曲线计算叶轮部件疲劳寿命。结果表明:与倒角半径相比,倒角角度对气动性能的影响更加显著,在大流量点倒角角度造成等熵效率减小幅度达5%左右,总压比减小幅度达0.07左右;与倒角角度相比,倒角半径更有利于减小应力值;选取经验参数对不同倒角尺度的离心叶轮进行估算得到的疲劳寿命值与实验值偏差最大为3%,最小仅为0.09%。
