トレンチドレインのメリットは、その効率性だけでなく、メンテナンスの容易さにもあります。定期的な清掃を行うことで、詰まりやすいゴミや汚れを取り除き、排水機能を保つことができます。さらに、これにより悪臭や昆虫の繁殖を防ぐことができます。

The number of grooves or lines per millimeter directly affects the grating's resolving power. Higher groove density allows for better resolution of closely spaced wavelengths, which is essential in applications like spectrometry. The efficiency of the 19w2% grating suggests that while it can achieve certain diffraction angles efficiently, there may be limitations in the amount of light that can be diffracted, pushing engineers to evaluate the trade-offs between efficiency, resolution, and the intensity of the light source.
