Cadillac Model M. In 1907, Cadillac offered two distinct touring car body styles for the Model M series: the elegant Victoria Light Touring Car and this "Straight" Light Touring Car. Both were powered by the single-cylinder Cadillac engine and priced at $950, or $1,025 with a top. In 1908, three Model M Runabouts similar to this touring car were randomly selected to prove that the precision manufacturing methods employed by Cadillac guaranteed complete interchangeability of parts.

1907年，凯迪拉克品牌为旗下的M系列车型提供了两种不同的车身设计：优雅风格的四轮折蓬式车型和直线型敞蓬车，这两种车型都配备了凯迪拉克的单缸发动机，售价从 950美元到1025美元。1908年，和这款四座敞蓬车相似的三款M型小型单座敞篷车的出现充分证明，凯迪拉克品牌的精密制造工艺和标准化的零部件生产，确保了汽车零部件可在不同车型之间交替使用。

The flow behavior of 5182 aluminum alloy for automotive body sheet at the strain rate ranging from 0.001 to 0.1 /s and temperature ranging from 323 to 573 K was studied on Instron8032 tensile tester. A constitutive equation using up-dated Fields-Backofen equation was established to describe the flow behavior of 5182 aluminum alloy during warm tensile.

摘 要：在变形温度为323~573 K、应变速率为0.001~ 0.1 /s条件下，采用Instron8032电子拉伸实验机对汽车用5182铝合金板的流变行为进行研究，采用修正后的Fields- Backofen方程描述5182铝合金温拉伸时的流变行为，建立5182铝合金在温拉伸时的应力－应变本构模型。

Io 伊俄 io was the daughter of a rivergod.she was loved,run after and won by zeus.hera became so greeneyed that she flew down from olympus one day to pay her rival back .zeus,however,had foreseen her arrival and changed io into abeautiful white little cow.seeing through the trick,hera asked for the cow as a present and zeus had to give in to her wish .then she left the cow to the care of a hundredeyed monster,argus.argus'' eyes were ever open and no escape was possible .

伊俄是河神的女儿，宙斯爱她，追求她，并得到了她。赫拉对此嫉妒不已。一天她飞下奥林波斯山向情敌施加报复。然而宙斯早已预见到她的光临，就将伊俄变成了一头美丽的小白牛犊，赫拉看穿了其中的诡计，非要一头牛犊作为礼物。宙斯无奈，只得让她如愿以偿。赫拉便将牛犊托付给百眼魔鬼阿刚斯看管。阿刚斯的眼睛永远睁着，要想逃脱是不可能的。
