查询词典 discontinuousness

Mostly, traditional arithmetic of image edge detection distill edge using gradient maximum or zero-crossing which base on gray discontinuousness on edge. They are affected easily by noise.

传统的边缘检测算法大都是基于边缘的灰度不连续性利用梯度局部最大值或二阶导数过零点来检测边缘，容易受噪声干扰。

The contemporary Chinese city which under the dual pushes of urbanization and globalization is taking a huge change. But with urban scale extends and quick improvement of infrastructure, it brings a series of new city problems. such as the city identity lost, context discontinuousness, disorder space spread, walking environmental depravation and the space meaning weaken etc., as a result, the culture of city which has been formed thousand years ago and it's physical environment are basically eroded .

当代中国城市在全球化与城市化的双重推动下正在发生巨变，伴随着城市规模的急剧扩张，基础设施的迅速改善，出现了一系列新的城市问题，诸如特色的丧失、文脉的断裂、空间的无序、步行环境的恶化，空间意义的弱化等，其结果，千百年来形成的城市文化及其载体正从根本上产生动摇，城市文明面临空前危机。

All kinds of geological processes not only make rock masses discontinuousness,heterogeneity and anisotropy, which result in the variability of rock masses'parameters and determine the indeterminacy of forms of rock failure and randomicityof engineer loads.

各种地质作用不仅使岩体具有不连续、非均质和各向异性等固有特性，导致岩体参数表现出较大的变异性，还决定着岩体破坏形式的不确定性和工程荷载条件的随机性。

However, the vast computation cost, the implicity of object function and discontinuousness of search space limit the application of traditional gradient-based optimization methods.

然而，由于计算时问长，目标函数无法显式表述，搜索空间可能不连续等因素，很难直接基于数值仿真通过梯度法进行设计优化。

Replacing GaAs by AlGaAs in buffer layer could increase conduction band discontinuousness at buffer layer junction.

在缓冲层以AlGaAs取代GaAs，能增加缓冲层接面之导带不连续情形。

The robotic Denavit-Hartenberg theory was firstly introduced to describe the Tooling virtual assembly procedure. Then the Tooling assembly mathematical model was established based on the Denavit-Hartenberg inverse kinematics and virtual assembly space constraint relationships for describing the position of robots theory in 3-D space. And to solve the problem of length discontinuousness of standard parts, the position adjustment strategy for Tooling vacuum group was studied and presented.

首次引入机器人运动学Denavit-Hartenberg模型，基于反向运动学原理和虚拟装配的空间约束关系，建立了Tooling空间装配的数学模型，并根据Tooling装配所用标准件长度不连续的特点，进一步给出了Tooling吸盘组件的空间位置调整策略。
