For elliptic shape , the mathematic equations resulted from the algorithm and the caculating method are given in detail , the computer simulation result is presented 文中以椭圆廓形曲线为例，给出了具体的数学模型和计算方法和计算机模拟检测结果。
Based on this and on the bell curve theory by king hubert , it can be reasoned that in the coming 20 years the general world situation of oil will essentially remain balanced 以此为基础，根据kinghubert的钟形曲线理论，可以作出如下推断：在未来20年内世界石油供需大势仍将基本保持平衡。
The rationality of cycloid gear actual operating space is verified by optimizer , finally the conclusion of the isometric plus travel distance alter shape curve much more approach corner alter shape is obtained 通过编制的优化程序验证了摆线轮齿形工作部分范围的合理性，得出了等距加移距修形曲线更逼近转角修形曲线的结论。
According to several boundary conditions , the frequency equation of flexural circular plate is calculated . similarly some coefficients in the displacement distribution can also be acquired , which provide a preparation for further study 在求得频率的基础上，进一步求解了与之对应的归一化了的振形曲线系数，从而为后面的计算铺平了道路。
In addition , based on the second order hilbert curve , some modifications have been done . with different kinds of substrates , the pattern - reconfigurable antennas and the broadband directional antennas are designed 第四部分,针对hilbert二阶分形曲线并做一定的改进,利用不同的介质材料,设计出方向图可重构平面天线以及宽带的定向天线,完成了部分原理性实验。
It is verified that the prediction accuracy of ship maneuvering hydrodynamics , turning motion and zigzag curve are acceptable in practice , if the learning samples , network ' s structure and learning algorithm are reasonable 研究结果表明，只要选择适当的学习样本、网络结构和学习算法，神经网络的水动力预报精度、回转运动预报和z形曲线的预报在实际中可以接受。
And introduced follows the general innovation proliferation as the innovation proliferation internet development " s " the shape curve theory , as well as our country at present the internet development the stage which in the shape curve locates in " s " 并且介绍作为创新扩散的互联网发展遵循的一般创新扩散的“ s ”形曲线理论,以及我国目前互联网发展在“ s ”形曲线上所处的阶段。
Because the choice of fuzzy set functions affects how well a fuzzy system approximates a function and gaussian bell - curve sets give richer fuzzy systems with simple learning laws , we choose gaussian function set as fuzzy set functions 因为隶属函数的选取会影响模糊系统逼近函数的效果，而高斯型隶属函数的钟形曲线只要简单的学习规则就可以表示丰富的模糊信息，我们选取高斯型隶属函数作为模糊集合函数。
For example , the word lengths of voynichese form a binomial distribution ? that is , the most common words have five or six characters , and the occurrence of words with greater or fewer characters falls off steeply from that peak in a symmetric bell curve 举例来说，伏尼契文的文字长度呈现二项分布，也就是最常见的字由5 ~ 6个字母组成，字母较多或较少的字，出现的频率和对称钟形曲线的最高峰相比，大幅降低。
This paper puts out the edge shapes curvilinear equations , of the edge shapes of double circular gear hob , and analyzes the tooth surfaces characterist . it also points out that the gear hob is a kind of approximate shape building cutting too ls in the whole course of using 本文提出了直槽双圆弧齿轮滚刀刃形曲线方程式，并进一步分析了该滚刀的齿面特性，指出该滚刀从整个使用过程看，是一种近似造型的刀具。
