The feasibility of the filtration by diatomaceous earth instead of charcoal powder in the TiO_2 production is described based on the principle of filtering and production practice.

从助滤原理和生产实验等方面阐述了硅藻土助滤剂代替木炭粉用于钛白生产的可行性。

It's a technique called collaborative filtering, and it works on the principle that the behavior of a lot of people can be used to make educated guesses about the behavior of a single individual.

这就是所谓的“协同筛选”技术，该项技术所依据的原则是：可以依据大多数人的行为对个体行为作出有根据的推测。

The way, based on the principle of inverse filtering for recovering the ideal signals, can be realized both in time domain and in frequency domain.

基于恢复理想信号频谱的逆滤波原理，利用通道均衡法对接收通道的失配进行了校正。 通道均衡可在时域或频域实现。

This defect allows one otherwise excluded wavelength to travel through the wire, permitting extremely precise filtering that could, in principle, be used to resolve many hundreds of individual signals carried along an individual fibre.
