profile shape

Takes the screw type compressor rotor as an example, a calculating method of unknown section profile of spiral surface and its conjugate shape is introduced and practical formulas are given.

以螺杆压缩机转子为例，介绍了未知螺旋面端截面轮廓及其啮合的共轭齿形求法，给出了实用计算公式。

In practical seismic data processing achievement profile, wave group characteristics of every reflection zone are clear, information of layer to layer is rich and wave shape is natural and stable.

在实际地震资料处理的成果剖面上，各反射层位的波组特征清楚，层间信息丰富，波形自然稳定。

Secondly, the technique of profile extraction based on duplicate wavelet transform is used to extract ultrasonic echo signal character owing to the trait of duplicate wavelet transform providing instantaneous phase information and the inherent relation between signal profile and object shape.

然后，根据复小波变换可以提供信号瞬时相位信息的特点，采用了复小波变换提取超声回波包络的方法，并提出一种根据包络线提取物体特征参数的技术；

The approaching method is one kind of method which can conform to the least zone principle best. While obtains the shape error, the position error between measured profile and its theory profile can obtained.

该方法是一种符合最小区域原则的轮廓度误差评定方法，并且在得到形状误差的同时，可以得到被测轮廓与理论轮廓之间的位置误差。

Image feature extraction mainly utilizes auto-extraction of low-level visual feature ( color, texture, profile, shape etc.) from image data, to deeply describe high-level semantic information.

提取图像特征主要利用从图像数据中自动抽取出底层特征，如颜色、纹理、轮廓和形状等特征，进而描述出高层语义信息。

Secondly, the profile shape, the white-collar youth pursue the aesthetic orientation such as simple and clear of overall outline, the version fit, nice cutting, varied profile, attention to details and exquisite workmanship.

其次在廓形方面，白领青年追求的是整体轮廓简洁清晰、版型合身、裁剪到位；局部轮廓富于变化、注重细节、做工精致的审美取向。

This is due to the special profile shape of the cams.

这要归因于凸轮特殊的外形.

Practice of improving the profile shape and performance of heavy plate

提高厚板板形质量和性能的实践

Shape features of coarse aggregates include contour shape, angular features and surface texture. Contour shape represents the overall shape ratio of a particle, angular feature is the prominent degree of the angular on the profile, and texture describes the surface roughness of a particle.

粗集料形态特征包括轮廓形状，棱角特征和表面纹理，轮廓形状表征的是颗粒的整体形状尺寸比例，棱角性表征的是颗粒轮廓上棱角的突出程度，纹理描述的是颗粒表面的粗糙度。

Firstly, geometric resolution algorithm for solving theory of the profile shape of the tool is researched by the motion of the tool relative to the workpiece.
