反正切 meaning in English
arc tangent
arctan
arcustangens inverse tangent
inverse trigonometric function
math.atan
Examples
- Inverse tangent function
反正切函数 - Arc - tangent function
反正切函数 - The atan ( ) function returns the arctangent of a number as a numeric value between - pi / 2 and pi / 2 radians
函数的作用是：返回一个指定数值参数的反正切值。 - The detailed works are as follows : the finding patterns problems in the time - series data sequence are described , and a new trend logic expression method is introduced , and its algorithm and experiment result of algorithm are given ; time - scries data are disposed , and using the arctg . slope of line as the sample of pattern recognition , so ignoring the aberrance of pattern in the classified . in addition , a new time - series pattern finding algorithm based on higher - order neural network is put forward
同时给出了本文的具体的工作，主要是：对在时序数据序列中发现模式问题进行了描述，并介绍了一种新的趋势逻辑表示方法，给出了其算法及算法的实验结果；对时序数据进行处理，提出了利用线段的斜率反正切值作为模式识别的样本，从而在分类时忽略模式的畸变；另外，还提出了一个新的基于高阶神经网络的时序模式发现算法。 - Tribology is an important factor that affects accuracy of finite element analyses . tribological specialties and major influencing factors of bulk metal forming is discussed in the present research . a friction model of bulk metal forming including the influence of temperature , normal pressure and strain on the tool - workpiece interface is developed on the basis of friction model developed by chen and kobayashi
本文对金属体积成形摩擦的特点和主要影响因素进行了分析,在反正切摩擦模型的基础上建立了基于成形温度、单位压力和变形程度等多因素变化的体积成形过程摩擦模型,可以充分地考虑体积成形中速度、温度、单位压力和变形程度对界面的影响。
