两方程对应的特征方程是恒等的。
The characteristic equations of the two equations are identical.
基准测试还可能有非恒等分布的可观察到的变量,它们也会影响性能。
Benchmarks may also have non-identically-distributed observable variables that may affect performance.
从第一个模板可以看出,与很多有用的脚本一样,这里也使用了恒等变换。
As with many useful scripts this builds on the identity transform, as you can see from the first template.
Pages and pages of them, so no one expects you to know all those identities, but there are a few popular ones we will use.
好几页的内容,我不要求你们都能记下来,但是我们会用到一些著名的恒等式
But since sine square plus cosine square is 1, you'll find this vector has a fixed length R.
但是由于正弦和余弦的平方和为1,你会发现这个矢量模长恒等于 R
