1.Finally carries on screening through the orthogonal experiment to the supplementary material, and find the best increase ratio.
最后，对辅料的添加进行了正交试验，找出最佳的辅料及其添加比例。
2.The simple transmission setup, compact structure, low noises and higher force increase ratio could be reached easily by the mechanism.
该机构是一种传动简单、结构紧凑、噪音小、增力比大且易于实现的驱动机构。
