查询词典 directional

For precision azimuth, as in gunfire control, a double-lobe pattern (figure 3) can give great directional precision by finding the direction in which the echo "pips" for both lobes are of equal heights. This is called "lobing".

By means of analyzing the difference between HVDC transmission line and traditional HVAC transmission lines, it is proved that it is not suitable to apply superposition principle to the power grid containing HVDC transmission lines, thus following conclusions are obtained: in the place near to HVDC transmission line the fundamental frequency fault component element should be not adopted; and there is definite relation between the maloperation of directional comparison pilot protection applied in practical project and the adoption of fundamental frequency fault component element.

通过分析HVDC的特性与传统交流系统的不同，证明叠加原理不能应用在含有HVDC的系统中，从而得出结论：在HVDC附近不应该采用工频故障分量元件，实际工程中的纵联方向保护误动作与使用工频故障分量元件有一定关系。

The experimental data demonstrated that there was a nasalward directional preference in oath OKN system under both close loop and open loop conditions, and the nasalward OKN gain evoked by stimulation of nasal retina was much higher than that at temporal retina. ms indicates that OKN nasalward preference is mairily derived from the nasal retina, i. e. the direct path1Vay of OKN dominates the indirect pathway in cat's OKN system. The gains of temporalward and nasalward OKN from temporal retina are much less than those of nasalward OKN from nasal retina. It is suggested that the indirect pathway of OKN in the cat only possesses a supplementary function, Which probably plays an important role in temporalward OKN eye-movments in relation to binocular vision.

实验结果显示：高速度刺激的闭环OKN反应及开环OKN反应均对鼻向运动刺激有明显的方向选择性；半侧视网膜刺激时，鼻侧半视网膜的鼻向OKN增益明显高于颞侧半视网膜的鼻向增益，说明猫的OKN眼动反应以跟踪鼻向运动为主，并且这种对鼻向运动刺激的选择性主要来源于鼻侧半视网膜，亦即来源于OKN直接通路；颞侧半视网膜的鼻、颞向眼动增益均明显低于鼻侧半视网膜的鼻向眼动增益，说明猫的OKN系统的间接通路在OKN眼动控制中起辅助作用，并可能主要对颞向OKN眼动起作用从而与双眼视觉功能相关。
