Retinal arteriolar tortuosity with retinal hemorrhage was first described in 1958. 摘要视网膜小动脉弯曲合并复发性视网膜出血在1958第一次被提出。
Retinal arteriolar tortuosity with retinal hemorrhage was first described in1958. 视网膜小动脉弯曲合并复发性视网膜出血在1958年第一次被提出。
The tortuosity factor, mechanical properties and flattening test shall be agreed by both the seller and the buyer. 其弯曲度、力学性能、压扁试验等由供需双方协议。
Then the total flexural curvature and the natural tortuosity of the centerline can be expressed with the change rates of deviation and azimuth angles. 另一方面,考察了井孔内具有抗弯刚度套管微元的平衡状态,建立了套管微元所应满足的控制微分方程及其差分格式。
