Asymmetric profiles of tip clearance have little influence on rotor peak efficiency , and the degree of degredation is in rat io of the level of asymmetry at circumferentioal direction 转子尖部间隙周向布局的变化对失速裕度及效率的变化起负面影响，且随着周向变化的程度加大，这个恶化趋势也加大，但对峰值效率的影响较小。
Sconed , the tangential shear velocity and the radial particle diameter distribution are derived according force balance in the annulus , in order to reduce or pervent the particle to remove toward the membrane surface 第二、根据粒子的力平衡理论推导出旋转流中粒子不向膜面沉积的周向剪切速率及径向粒径的分布规律，并指出径向速度对粒子沉积的影响。
The energy equation of the thrust chamber wall was developed by omitting radical heat conduction and only considering the radiation heat transfer of the four chambers , the radiation leakage through nozzle exit , the axial and circular heat conduction 忽略径向导热，考虑推力室外向的相互及自身辐射交换、内壁经喷口的辐射泄漏以及周向和轴向的传导热量，建立了推力室壁的能量方程。
Through check and inspection to the large pipe piles of zhejiang beilun power plant ' s pier , a lot of cracks were found in portrait and circle on the surface of prestressed concrete pipe piles which affect security and durability of the concrete structures directly 摘要通过对北仑电厂码头大管桩的详细调查与检测，发现混凝土大管桩多处存在纵向裂缝和周向裂缝，直接影响码头混凝土结构的安全性、耐久性。
The unhomogeneity of the loop ' s structure in the remeshing lines was found after the vascular prosthesis has been warp knitted , which is the main reason why . the rupturing position of the prosthesis endured circumferential traction localized preferentially on the remeshing lines 研究还发现在经编加工后线圈结构在连接部位已存在一定的不均匀性，这是人造血管在周向拉伸中该部位具有高断裂的主要原因。
