附录 C：施加预应力的方法
"反复拆装会降低所需的扭矩。"Waanders，第 49 页
- 拧紧叠堆螺栓 - 使不均匀应力平均化
- 使用压力机（Jones 专利）- 释放压力机压力时应力可能部分松弛
Appendix C: Method for applying prestress
"Repeated assembly and disassembly reduces the torque required." Waanders, p. 49
- Tightening stack bolt - averages nonuniform stress
- Using a press (Jones patent) - stress may be partially relieved when press force is released
