Therefore, its quantum state can be represented as a wave, of arbitrary shape and extending over all of space, called a wavefunction. 因此，其量子态可以表现为波，形状任意而扩展遍及整个空间，称作波函数。
In our free particle example, it turns out that it is impossible to find a wavefunction that is an eigenstate of both position and momentum. 我们以自由粒子为例，找到既有位置又有动量的波函数是不可能产生的。
