查询词典 filter

SRC in SDR is also discussed, and two improved structures of CIC filter are presented. The first one is a CIC decimation filter based on polyphase structure and partially sharpening technique, which is suitable for the situation where the requirements in passband attenuation is not very high while the requirements in alias suppression and operating speed are relatively high. The other one is an improved CIC-Rotated Sinc decimator which possesses improved frequency response, low operating rate and low cost in hardware as well.

研究了软件无线电中的采样率转换技术，给出两种改进的CIC滤波器结构；(1)基于多相结构和部分尖锐化的CIC抽取滤波器，该结构适用于通带衰落要求不是很高，混迭抑制和滤波速度的要求相对较高的场合(2)一种改进CIC-Rotated Sinc抽取滤波器，该结构在获得好的通阻带特性的前提下，一方面降低了整个CIC滤波器结构的工作速率，另一方面尽可能地降低硬件实现的复杂度。

Stent should be soft, with good lateral bending property, and diameter of the stent should be 1.0-2.0 mm longer than the actual stenosis. Implantation technique should be improved. These can reduce extrusion and cutting action of the atheromatous plaque due to balloon dilatation and stent expansion, and prevent plaque defluxion during implantation. Filter protection device is used to filter tissue debris and to prevent microemboli entering cerebral circulation, which can elevate safety of carotid stent implantation.

选择相对柔软的，侧弯性能较好，且直径应比狭窄处实测直径大1.0~ 2.0 mm的支架，提高置入操作技术，可以减轻支架置入过程中球囊扩张及支架膨胀时对粥样斑块的挤压与切割作用，防止斑块脱落，同时使用滤器脑保护装置以过滤较大组织碎片，阻止较大微栓子进入脑循环，提高颈动脉支架置入的安全性。

The performance of traditional particle filter would be degenerate in alpha stable distribution noise.A new fractional lower order particle filter based on fractional lower order model was presented in this paper,and the detailed operation algorithm was proposed.

在alpha稳定分布噪声下，传统的基于二阶模型的粒子滤波器性能会出现退化，文章提出了一种基于分数低阶模型的分数低阶粒子滤波器，并给出了具体的运算公式。

The improved method of filter sampling off-line analysis using both parallel plate organic denuder and backup filter has a good agreement with in-situ online measurement.

同时采用平行板有机物扩散吸收管和后置膜的离线分析方法同在线观测的结果具有比较好的一致性。

The rotation,detergence,and valve switching of the water-filter system are full-automatically controlled and, besides,the filter can well deal with the damage of generator set caused by sewage.

本文采用PLC实现新型滤水器，在旋转、排污、开关阀方面实现了全自动控制，并很好地解决了因水质污染对电厂发电机组带来的危害，克服了国内其它形式的滤水器无法解决的有机物过滤排污问题。

If the diamond—shaped filter banks are error—free, the fan filter bank is also error—free.

若采用无失真的菱形数字滤波器组，扇形数字滤波器组的重建误差为零。

According to the defect of different type in log, histogram balance, fast average filter, fast mediate filter, differentiation sharp, Laplace sharp operator, Sobel sharp operator, Kirsch sharp operator, etc.

针对原木中不同类型的缺陷，本文采用的处理方法有直方图均衡、快速均值滤波、快速中值滤波、微分锐化、拉普拉斯算子锐化、Sobel算子锐化、kirsch算子锐化等算法。

This paper analyzed data from multiple sources and different structures, concluded three types of info: Login info, Event info, and Packet data info, then created the formation for every type of data; In order to combine future possible new data, IDS using profile and formation string together, create and practice data formation standard algorithm; Because in the collected data, there is info that is redundant or has minor effect on the IDS, this paper discussed the rules of redundant data differentiating and safe data differentiating, Then create data filter rule base; Data collecting system uses distributivity design, collecting module like a black box. we can get data which was filterd and had standard formation, if we created a new model string for new data source. Module work individually; filter data right away at the collecting node.

本文分析了多种来源的、不同结构的数据，将其总结成登录信息、事件信息和网络数据包信息三种类型，并为每种类型的数据设计了固定的格式；为了与将来可能出现的新型数据兼容，采用了配置文件与模式字符串相结合的方法，设计并实现了数据格式标准化算法；由于收集到的数据中存在冗余的信息和对入侵检测影响不大的信息，本文分别讨论了冗余数据辨别规则和安全数据辨别规则，并建立起数据过滤规则库；数据收集系统采用分布式设计，收集器以黑盒形式提供，对新的数据源只需设计一个新的模式字符串，即可得到过滤后的、具有标准格式的数据，各收集器间独立工作；在收集点即对数据进行过滤，只向分析中心报告可疑数据，以减少传输和存储的数据量，降低对网络性能的影响。
