Return a new dictionary initialized from an optional positional argument or from a set of keyword arguments 返回一个新的由可选的位置参数或一组关键字参数初始化的字典。
Named arguments can only be used to set the values of fields and properties of attribute classes 构造函数中，必须使用位置参数。命名参数只能用于设置属性类的字段和属性的值。
Source data is copied into , and aligned within , this target area according to the specified alignment instruction 源数据将以一定的位置拷贝进去，而具体的位置将依赖于函数的位置参数。
If the positional argument is a mapping object , return a dictionary mapping the same keys to the same values as does the mapping object 如果位置参数是一个映射对象，则返回像映射对象一样的键值映射。
However , in the case of attributes , once the positional parameters have been stated , the user can reference fields or properties with the following syntax 但是，对于属性而言，一旦声明了位置参数，用户便可以使用以下语法引用字段或属性：
It is shown that the spectral splitting can take place in the near field , which is dependent on the spatial correlation and bandwidth of the spectral source and position parameters 研究表明，在近场会有光谱分裂出现，光谱分裂与光源的空间相干性和源光谱的谱宽以及位置参数有关。
The actual - operating parameter ( level angle , pitching angle , speed etc ) of theodolite are measured by code check of theodolite , and sent to computer by the interface 教练员可通过系统提供的输入界面输入目标的位置参数及目标飞行轨迹的特征点。经纬仪的实际运动参数由经纬仪自身的码盘测出，并通过计算机接口输入到计算机中。
The accuracy of parameters of virtual vehicle model influences the reliability of simulation results , and the most important factor is the error of suspension positioning parameters caused by the vehicle equilibrium analysis 摘要虚拟样车参数的精确度直接影响到仿真结果的可靠性，其中由车辆静平衡求解带来悬架位置参数的偏差对仿真结果的影响较大。
This text analyzed the affect to the extreme phase difference change by different design parameter （ the position parameter of eccentricity and data of eccentricity ） ， and get variety regulation ， by analyzing all data that came from optimal design process 在对全部优化数据分析过程中，分析了相关设计参数（偏心位置参数及偏心量）变化对极限相位差的影响，并得出了相应的变化规律。
Based on the analysis of the scraped mark made by a vehicle body and another vehicle tire , a method to determine the relative speed of the two vehicles is put forward , while the position of the point who made the scraped mark is not known 摘要通过分析车轮与车身相互刮擦时所产生的刮擦痕迹，提出了在刮擦点的位置参数不能获得时，单纯依据刮擦痕迹包含的信息估计交通事故中肇事车辆速度的方法。
