英文释义

名词 n.
  1. An imaginary number (in the case of complex numbers, usually denoted i) that is defined as a solution to the equation x²=-1.
    — In Section 4.3 we introduced the imaginary unit i with (i)²#61;-1, in the complex space domain. In section 4.4 we introduced the complex unit j with (j)²#61;-1, in connection with the time dependency of the shape (4.4.16) of the swimming profile. These different imaginary units have no interaction, we leave unaltered the product ij.
