每月的时事通讯将包含有关不堪重负的父母的故事，并提供指导，指导无子女的成年人如何应对准祖父母采用的各种游说策略。
A monthly newsletter would contain stories about overwhelmed parents and offer guidance on how childless adults can respond to the different lobbying tactics that would-be grandparents employ.
对负荷增大，但磨擦系数无敏感变化，因此重负荷下，磨擦系数极小，并且长期保持精度不变，可得机械使用寿命长期保持。
On the load increased, but not sensitive to changes in friction coefficient, so heavy, the friction coefficient is extremely small, and the same long-term accuracy can have long-term mechanical life.
