Timing hand-grip is moved in axial direction to realize multilevel timing, reversing valve is controlled with reversing hand-grip to realize reversing output. 用调速手柄作调速轴向移动,实现多级调速,用换向手柄控制换向阀,实现换向输出。
Results Serum albumin was positively correlated with hand-grip strength and serum creatinine. Serum albumin was significant lower in malnourished patients. 结果血清白蛋白水平与握力、血肌酐显著相关,营养不良的患者血清白蛋白显著降低。
