求翻译：如果我们引入一个或一些另外的变量来描述自变量与因变量的变化，引入的变量本来并不是当前问题必须研究的变量，我们把这样的变量叫做参变量或参数。是什么意思？

If we introduce one or a few additional variables to describe the independent variable and dependent variable changes, the introduction of the variable is not the current problems would have to look at the variables, we call such variables reference variables or parameters.

If we introduce one or some other variables to describe independent variables with the introduction of a variable, and change the variable would have NOT problem at the present time, we must study the variables to the variable called the variable or parameter.

If we introduce or some other variables describe the independent variable and the dependent variable change, the introduction variable is not originally a variable which the current problem must study, we such variable named parameter or parameter.

If we introduce a or some other change of variables to describe the independent variables and dependent variables, the variables have been introduced are not variables of the current problem must be studied, we called parametric variable or parameter.
