On numerous drives throughout my childhood, my mother would suddenly pull over the car to examine a flower by the side of the road or rescue a beetle (甲虫) from certain tragedy while I, in my late teens and early twenties, sat impatiently in the car.

Though Mother’s Day follows Earth Day, for me, they have always been related. My mom has been “green” since she became concerned about the environment. Part of this habit was born of thrift (节俭). Like her mother and her grandmother before her, Mom saves glass jars, empty cheese containers and re-uses her plastic bags.

Mom creates a kind of give-and-take relationship with wildlife in her yard. She knows to pick the apples on her trees a little early to fend off the bears and that if she leaves the bird feeders out at night, it’s likely they’ll be knocked down by a family of raccoons (浣熊). Spiders that make their way into the house are captured (捕获) in a juice glass and set loose in the garden.

I try to teach my children that looking out for the environment starts with being aware of the environment. On busy streets, we look for spent (开败的) dandelions (蒲公英) to parachute; we say hello to neighborhood cats and pick up plastic cups and paper bags. This teaching comes easily, I realize, because I was taught so well by example. Mom didn’t need to lecture; she didn’t need to beat a drum to change the world. She simply slowed down enough to enjoy living in it and with that joy came compassion and an instinct (本能) for preservation.

I am slowing down and it isn’t because of the weight of my nearly forty years on the planet, it is out of my concern for the planet itself. I’ve begun to save glass jars and re-use packing envelopes. I pause in my daily tasks to watch the squirrels race each other through the palm (棕榈树) leaves above my porch (门廊).

Last summer, in the company of my son and daughter, I planted tomatoes in my yard. With the heat of August around me, I ate the first while sitting on my low wall with dirt on my hands. Warm from the sun, it burst on my tongue with a sweetness I immediately wanted to share with my mom.

某施工单位承担一台大型压缩机和一台配套的燃气轮机的吊装任务，压缩机单重为82t，燃气轮机单重为37.41t，整体到货。在施工现场可提供200t、170t的大型汽车式起重机各一台。200t、170t汽车式起重机吊索具重量均为2t。由于现场条件限制，两台起重机的最佳使用工况如表3-2。
两台起重机的最佳使用工况

汽车式起重机	吊车臂长/m	作业半径/m	额定负荷/t
200t	24.4	9	71
170t	22.7	7	75.5

注：如果用抬吊时，不均衡荷载系数取1.1。
