定向构造（oriented structure）是物理学术语，指岩石中的矿物平行某一平面或某一方向排列所形成的构造，统称为定向构造。如千枚状构造、片状构造、片麻状构造、条带状构造及线理等都属于定向构造。
这种过滤通常是通过构造命令管道线 来完成的，其中来自一个命令的输出被导入 或重定向 为下一个命令的输入。
Such filtering is most often done by constructing a pipeline of commands where the output from one command is piped or redirected to be used as input to the next.
通过研究说明，定向滤波方法为多组系构造的分析及裂缝性气藏的井的布署增添了新的手段。
The research shows that by use of the directional filtering method, a means for the multiple structure analysis and the disposition of Wells in fractured gas reservoir has been added.
采用类似于交流电机磁链观测的方法来构造一个虚拟电网磁链，可以代替电网电压作为PWM整流器矢量控制中的定向矢量，达到省去交流侧电网电压传感器，降低PWM整流器成本的目的。
So a virtual line flux has been constructed to serve as the oriented vector instead of the line voltage vector to remove the AC voltage sensors and reduce the cost of PWM rectifiers.
