On the other hand, the mill housing works under pulsating load, so the fatigue damage can take place. With Miner formula and the P-S-N curve of the mill housing, fatigue life is predicted through being programmed in FORTRAN language.

另一方面，由于机架是在脉动载荷下工作，有发生疲劳破坏的可能，本文采用修正的Miner法则，结合机架的P-S-N曲线，通过FORTRAN语言编制程序，预测了机架的疲劳强度可靠性寿命。

Objective: The experiment is to study the Influence of Opuntia Milpa Alta on the exhausted swimming time and biochemical index of blood and organs of mice, probe into the Anti-Movement-Fatigue function and possible mechanism of Opuntia Milpa Alta and offer the theoretical foundation for its development and application in the field of sports activity.

米邦塔仙人掌对小鼠运动性疲劳影响的实验研究目的：通过研究米邦塔仙人掌对小鼠力竭游泳时间、血液和组织生化指标的影响，探讨其抗运动性疲劳作用及其可能机制，为其在运动领域的开发和运用提供理论依据。

Opuntia Milpa Alta prolonged the exhausted swimming time of mice notably, strengthened the LDH activity, accelerated the removing of the LA and BUN, strengthened the SOD activity of liver and skeletal muscle, accelerated the removing of the MDA content of liver and skeletal muscle, demonstrated positive Anti-Movement-Fatigue function. We inferred one of Anti-Movement-Fatigue mechanism was that Opuntia Milpa Alta could increase the exercise ability and load adaptive capacity of the organism and accelerate the removing of metabolites.

米邦塔仙人掌能显著延长运动组小鼠力竭游泳时间，增强运动小鼠的乳酸脱氢酶活性，加快血清乳酸和尿素氮的清除，增强运动小鼠肝脏、骨骼肌超氧化物歧化酶活性，加快肝脏、骨骼肌丙二醛的清除，显示出了积极的抗运动性疲劳作用，并推测其抗运动性疲劳的机制之一是通过增强机体运动能力和负荷适应能力，加快代谢产物的清除起作用。
