介绍用相位测距仪实现波长标准及在大长度范围内传递长度单位尺寸的情况。
The situations of realizing wavelength standard with phase diastimeter and transmittinglength unit size within a large range are introduced.
如果标签上表明“紫外线吸收波长至400nm”或者“达到ANSI紫外线标准”，那么就是有效的。
If the label says "UV absorption up to 400 nm" or "Meets ANSI UV Requirements" these are effective.
不过问题在于，客户对LED照明器具的要求不仅局限于标准照度或波长而已。
Yet herein lies the issue, as customers are not defining the LED fixtures by only the standard Lux and wavelength requirements.
