参数传递

But in fact, the system of half-tracked air-cushion vehicle is over complicated. When the vehicle drives in an unknown soil, the parameters and structures of controlled member will change with load or disturbances. This system is nonlinear and time-variant, and it is very difficult to analyze its transfer function and state function quantitatively.

然而在实际工作中，由于本课题中的系统过于复杂，当行驶在未知土壤条件下时，被控对象往往随着载荷或干扰因素影响，其特性参数或结构发生改变，属于非线性和时变性的不确定系统，它的传递函数或状态方程难于用传统的定量分析方法加以实现。

In many cases important information is carried by singularities that are not necessarily associated to a certain amplitude pattern.

在许多情况下，重要的地质信息可能是通过与振幅特征无关的奇异性参数来传递的。

Only the argument is passed into our function.

传递给我们的函数的只有参数。

Coupling is due to interpretation of data i.e. meaning of data that passed as argument to the member function of another class.

耦合是由于数据的解释，即该作为参数的另一个类的成员函数传递数据的含义。

Your normal habit when passing an argument to a function should be to pass by const reference .

用常量引用给一个函数传递参数，是一种好的习惯。

If this is a value type, the argument will be passed by value and copied twice.

如果它是一个值类型，则该参数将被以值的方式传递，并复制两次。

This style of function definition is best when any type of argument may be passed into the function.

这种函数定义方式最适合有多种类型的参数需要传递时的情况。

Dynamic large-signal, DC, and small-signal circuit models including parasitic resistances and current ripples of nonideal synchronous rectifier buck converter operating in CCM are established. Closed-loop modeling of nonideal synchronous rectifier buck converter for voltage-mode control is studied. Transfer functions are obtained. Effects of parasitic components on control loop design of the converter are explored. Systematic simulation analysis is performed. All the results show that it is necessary to include parasitic components of converters into equivalent models.
