找Bohr理论的学弱项,Bohr说:第二段最后一句话 he concluded that the physical of a quantum object is actually undetermined before the object is observed via experiment. 说明量子物质其实在实验观察前就已经被破坏。E选项说量子物质与欧持续不变的物理形态,不会因为实验方法而改变,对Bohr理论进行了削弱

条件一成立,虽然有两种情况了,但是题目已经说了n is an integer between 3 and 9,所以可以排除n是负数的情况
题目求的是,1.06J-1.06M=?
2)2^2 * 3^2 * 5^2 * 7^2 之积为n^2. 这样也是四个不同的质因素
这道题条件一就可以,c/a=3/2, c=1.5A, 代入原式, a可以被约掉,直接可以求出平均值
如果(2)n是12的倍数,那n绝对可以整除6,所以选B
条件2的两种情况, 举两个栗子:
没审题,(1)a/b大了,不能证明什么,(2)b大了,但是也不行
B. 'ultimately' modifies 'reduce'; ‘end up expressing‘ is redundant.
research 也可以做不及物动词呀?和 into,on搭配?
A说的是pollution control equipment会卖的好,但是原文中提的是manufactured goods啊。
