imaginary number
虚数───imaginary number
universal gravitation field is described by imaginary number in the paper. It's energy density is negative real number. And it accord with conservation of energy.───虚数场描述万有引力场，其场能密度是负实数，满足能量守恒定律。
If you had one negative number in it, then the product would be a negative number and, if you took a root of that, then you might get an imaginary number.───如果这当中有一个负数，乘积就会变成负的，如果你对一个负数开根号，你就会得到一个虚数。
The third to last panel is an imaginary number.───第三张图是错的吧？
The third to last panel is an imaginary number.───倒数第三张图是错的吧？
The universal gravitation field is an imaginary number field───万有引力场是虚数场
imaginary number in preprocessor expression───预处理表达式中出现虚数
If you had one negative number in it, then the product would be a negative number and, if you took a root of that, then you might get an imaginary number. We don't want to use it in that case.
