简要地导出了一般教材上较少提及其推导的四点弯曲加载因子。
The load factor for 4-point bending test, whose derivation is usually not included in textbooks, is also derived in this paper.
方法：采用四点弯曲细胞力学加载仪对成骨样细胞MG - 6 3分别以不同强度的张应力进行力学刺激，并对其受力后的增殖状态进行了研究。
Methods: the osteoblast-like cell MG-63 were stimulated with different amplitude by four-point-bend loading device, and the different proliferative index after tension-stress load were studied.
