In the temperature regex, the beginning-of-line and end-of-line operators are two examples of zero-width assertions, or matches that are positional, not literal.
在温度regex中，行开头和行结尾操作符是两个零宽度断言示例，或者匹配位置而非文字。
If so, a comma "replaces" the zero width assertion.
如果是这样，逗号将“替换”零宽度断言。
The width of each subinterval goes to zero .
每个子区间的宽度趋于零。
A media query consists of an optional media type and zero or more expressions that limit the style sheets' scope by using media features, such as width, height, and color.
一个媒介查询由一个可选的媒介类型和零个或多个通过使用媒介特征，比如宽度，高度，颜色，来限制样式表范围的表达式组成。
It is also found that there exists a maximum isolated structure period at which the height width ratio is zero or the displacement of the rubber bearing exceeds the allowable value.
研究还发现，存在一个最大的隔震结构周期使高宽比限值等于零或隔震层位移超过容许值。
