In order to ensure no light leakage, no water seepage, must use neutral silica gel sealing panel and the buckle side contact (which is a waterproof measures easily and effectively in low cost).

为保证不漏光、不渗水，必须要用中性硅胶密封面板与扣边接触处（这也是一种容易有效成本低廉的防水措施）。

Recessed-light fixtures are another air-leakage source because many designs require some airflow to prevent them from overheating.

藏灯是另外一个漏风的地方，因为许多设计师都通过这样的设计促进空气流动避免灯光设备出现过热。

Low current measurement applications include capacitor leakage, low current semiconductor, light, and ion beam measurements.

弱电流测量的各种应用包括电容器的漏电、弱电流半导体、光和离子束测量等。

The PT-AE8000U generates deeper blacks by incorporating Panasonic's Pure Contrast Plates, which match the LCD panel characteristics, virtually eliminating light leakage.

SKA, however, would be able to detect the leakage into space from a standard terrestrial television transmitter at a range of half a dozen light years or so.
