地壳

Low levels of the crust, melting point 3180 ℃, boiling point 5627 ℃, the relative density of 2053, the external F electronic structure 5d56s2, reaction time will be lost 1-7 electronic, but also can capture an electron, so oxidation number of 0,± 1, 2 , 3, 4, 5, 6 and 7, rhenium with the halogen in the fluorine, chlorine, bromine reaction halides dissolved in water, can dissolve in nitric acid and ammonia hydrogen peroxide solution, but do not dissolve in hydrochloric acid.

地壳中含量很低，熔点3180℃，沸点5627℃，相对密度2053，外围F 电子结构5d56s2，反应时会丢失1—7个电子，也可捕获一个电子，所以氧化数为0、±1、＋2、＋3、＋4、＋5、＋6和＋7，铼能与卤素中的氟、氯、溴反应生成溶于水的卤化物，能溶于硝酸和含氨过氧化氢等溶液，但不溶于盐酸。

A: Acceleration is the rate of change in velocity of the ground shaking (how much the velocity changes in a unit time), just as it is the rate of change in the velocity of your car when you step on the accelerator or put on the brakes.

答：地震加速度是地壳震动速度的变化率（在单位时间内速度改变量），就像你踩下油门或者刹车以后，你的汽车的速度变化率。
