In order to improve the accuracy of fingerprint directional image further, combining the advantage of the continuity of the point directional image with the advantage of the robustness of the block directional image to the noises in the fingerprint image, a novel concept on the continuously distributed directional image/field and the method to compute it in the fingerprint images are develope...

实践证明这种连续分布方向图过渡平滑、自然，既具有很好的连续性、渐变性和抗噪性，又具有极高的精确度，还兼有指纹点方向图的连续过渡性和块方向图的抗噪性优点。

When an earthquake occurred, the balanced post would tilt in the direction of the quake, push a rod, and cause the corresponding dragon's head to disgorge a bronze ball, which would then fall into the mouth of a bronze toad below.

哪个方向地震，柱子就倒向那个方向，触动杆子，那个方向的龙嘴就张开，吐出铜球，落在下面仰头张嘴的小铜蛤蟆口中，这样，人们就知道那里发生了地震。

The solid flow rate of aeration downflow was slightly less than that of aeration horizontal.

由整体方面来看，通气方向向下时的固体输出量虽略小於水平方向通气，但比较标准偏差可知通气方向向下时，下降管的压力扰动相当小，即可得到较稳定的操作。

The solid flow rate of downflow of inlet gas was slightly less than that of horizontal flow of inlet gas. But the standard deviation of pressure signals of downflow of inlet gas decreased significantly, causing more stable operation.

由不同通气方向来看，通气方向向下时的固体流量虽略小於水平方向通气，但可使下降管中的压力扰动明显减少，即可得到较稳定的操作。

However, the output beam quality of semiconductor laser is poor. Because of the waveguide properties of their active areas, semiconductor lasers generate large divergence-angle beams with elliptically shaped intensity profiles.

由于半导体激光器的结构特点，使得它发出的光束在垂直于结平面方向上远场发散角和平行于结平面方向的远场发散角相差较大(在垂直和平行于结平面方向上的发散角大小分别在30°左右和10°左右)。

Two methods of correlation of parasequence are put forward in fan delta and near shore sub-water fan sedimentary environment.

提出了在扇三角洲和近岸水下扇沉积环境中沿物源方向的相序递变对比法和垂直物源方向的侵蚀叠置对比法2种准层序对比模式以及在扇三角洲沉积环境中沿物源方向的扇三角洲前缘亚环境中的层组相变对比模式和近岸水下扇环境中叠置砂体对比模式、相变对比模式、薄砂层对比模式、相似渐变等5种层组对比模式。

Feasible region of unit-sphere was defined by standard if angle between normals and stamping direction was less than 90°.

以冲压方向与网格法线夹角不大于90°为冲压方向可行的判据，确定在单位球面上的冲压方向可行域。

He couldn ' t decide which way they should escape, English, Fitz or Percy.

他无法确定，他们究竟应该从哪条路出逃，向英国方向，向费兹方向还是向珀西方向。

So it is necessary to research on the definition, classification, characteristics, calculation, and formal model of directional relationships.

因此得出结论：研究空间方向关系中的最基本问题，即空间方向关系的定义、性质、特点、分类、形式化描述机制、基本计算等，是研究工作的当务之急，研究新的空间方向关系形式化描述模型很有必要。

The wedge feature maximum of Fourier coefficient gives the direction of every texture layer of X-ray tyre image; the algorithm will map the ring feature maximum of Fourier coefficient to the scale parameter of gabor filter, and then automatically search the refined scale and accurately direction parameters in the guide line of energy convergence.

根据这些特点，提出了一种方向Gabor滤波器参数的自动选取方法。根据楔特征人工指定纹理的大致方向，算法将环特征映射到Gabor滤波器的尺度参数，并按能量收敛原则搜索最好的尺度和纹理的准确方向。
