查询词典 filter flask

The article gives a design of an NIR instrument with filter. The working theory of the instrument is: during wheel running a circle , ray from light source irradiates the sample after it through a certain filter of filter wheel, so ray would carry the absorption spectrum of sample . We can know components of the sample by analyzing the ray . Filter wheel is its light splitter.

本文给出了一个使用滤光片作为分光器件的近红外光谱仪的控制电路设计方案，其工作原理是：当滤光轮转动时，光源出射光经过滤光轮上的某一滤光片，再照射到样品上，经样品池出射的光携带有样品的吸收光谱信息，滤光轮转动一圈，可得到样品不同波长处的光谱信息，通过后期数据分析可得到样品的成分含量信息。

From dead-end to open-end, surface velocity increases gradually if the filter passage is shorter and surface velocity of both ends is large than that of middle section if the filter passage is longer. Compared with cylindrical filter, the distribution of surface velocity of conical filter is more uniform.

当过滤通道较短时，过滤元件表面速度沿过滤元件轴向逐渐增大；当过滤通道较长时，过滤元件两端的过滤速度比过滤元件中部的大；同圆柱形过滤元件相比，锥形过滤元件过滤速度的分布更为均匀。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
