Infix notation is a common way of writing expressions, while prefix and postfix notations are primarily used in computer science.
中缀表示法是书写表达式的常见方式，而前缀和后缀表示法主要用于计算机科学领域。Read the infix expression from left to right, one character at a time.
从左到右读入中缀表达式，每次一个字符。When parsing expressions written in infix notation, you need parentheses and precedence rules to remove ambiguity.
对以中缀表示法书写的表达式进行语法分析时，需要用括号和优先规则排除多义性。Evaluating a postfix expression is simpler than directly evaluating an infix expression.
对后缀表达式求值比直接对中缀表达式求值简单。Infix notation is the conventional notation for arithmetic expressions.
中缀表示法是算术表达式的常规表示法。Alternatively, a delimiter type of Infix can be specified.
或者，可以指定Infix（中缀）类型的分隔符。The three most common forms of notation in arithmetic expressions are infix, prefix, and postfix notations.
算术表达式中最常见的表示法形式有中缀、前缀和后缀表示法。The infix index would match substrings anywhere within the string.
中缀索引将匹配在字符串内任意位置的子字符串。Using reverse, change the wheel direction of rotation, in order to achieve backward moving car. 3, interrupt power.
应用倒档，改动驱动轮的旋转方向，从而实现汽车倒向行驶。3、中缀动力。
