与应变同相的实数部分模量，通常称为 储能 模量。

The real part of the modulus is often called the storage modulus.

事实上，它通常是一个复数的形式，包括普通数字的实数部分和需要乘以负一的平方根的虚部。

In fact, it can generally be a complex number with both a "real" part that's an ordinary number and an "imaginary" part that's multiplied by the square root of one.

在第2部分中，我主要关注这样一些函数，它们的目的是操作浮点数，而不是抽象实数。

Here in Part 2, I focus on the functions that make sense only when you realize that they're designed for operating on floating-point Numbers instead of abstract real Numbers.
