有向量

In principle, there are two methods of describing glyphs in fonts:bitmaps and vectors.

原则上，在字体中有两种描述符号的方法：点阵和向量。

There are many situations where observed data are in the form of direction cosines or vectors but with an unknown positive scalar so that only the direction is known.

实际中常有这样的情形，当我们观察到的数据是以方向的形式或者以向量的形式给出但却具有未知的度量单位，因而只知道它们的方向，这时我们观察到的就是球面数据。

In line with port logistic characteristic of port logistic, the article puts forward throughput capacity combination forecast method, and makes contrast analysis between this method and expectation value, lineal regress and index smoothness.

针对港口物流发展规律及不同预测方法的不同特点，本文提出了基于最优组合预测权重向量的组合预测方法和基于定性、定量预测不同时间效应的时变权重综合预测模型，使最后的预测结果更具有科学性、合理性和可达性。

After the vein pattern was segmented from the vein image by an improved NiBlack method,authors obtained the vein pattern skeleton by an improved conditional thinning algorithm.On the basis,the algorithm extracted seven modified moment invariants of the vein pattern skeleton as the input vector of SVM for the recognition of vein pattern.The experiments on a database including 500 samples has achieved a recognition rate of 95.5%,and it indicates the algorithm is effective.

算法在采用修正的NiBlack算法从原始图中分割出静脉纹路，然后采用改进的条件细化算法进行细化获得静脉骨架的基础上，提取静脉骨架的7个修正的几何不变矩作为支持向量机分类器的输入进行静脉分类识别，在有500个样本的数据库上进行实验，获得了95.5%的识别率，表明了算法的有效性。

The equation which process screw surface with tools of disk conical surfaces was established by using Euler vector principle in the paper,from which we can see that this method has better applicability and validity and the advantages of faster speed.

本文利用欧拉向量原理建立了用盘状锥面刀具加工螺旋面的方程式，从中可以看出这种方法有很好的实用性和有效性，而且具有计算速度快捷的优点。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.
