This type of object is known as a functor or function object.
这种类型的对象称为functor或者function object。
In usual cases of method invocation the return result is a function object, which is then executed.
方法调用通常返回的结果是一个函数对象,然后执行这个函数对象。
The returned function is created using the lambda construct, which dynamically creates a new function object.
返回的函数使用 lambda 结构创建,该结构动态创建新的函数对象。
Now, I hope you guys know that much calculus, that when you take a derivative of a function of a function, namely v square over 2 is a function of v, and v itself is a function of t, then the rule for taking the derivative is first take the v derivative of this object, then take the d by dt of t, which is this one.
我希望你们了解更多的微积分知识,当你对复合函数求导时,也就是说v^/2是关于v的函数,而v本身是关于t的函数,求导的法则应该是,第一步是这一部分对v求导,然后v再对t求导,得到这一部分
