Ranges are named collections that are keyed by a numerical range limit and have a String value representing the name of the numerical range. Ranges是指定的收集,它由数值范围限制键控,并且拥有一个表示数值范围名称的String值。
In other words, the values are not associated with numerical index values within the array but actual string values. 这表明这些值不是与数组中的数字索引值关联,而是与实际的字符串值相关联。
The setlocale() call determines the character set, error messages catalogs, monetary value formatting, numerical conventions, string collation, and alphabetic ordering. 可以调用setlocale()来确定字符集、错误消息类别、货币值格式、数字转换、字符串校勘和字母排序。
Application of Numerical Simulation of Pressure and Temperature to Calculate Deformation Amount of Packer String 压力温度数值模拟在管柱变形计算中的应用
And different from other toolbox, the toolbox is not based on numerical analysis matrix, but use a string for symbolic analysis and calculation. 和别的工具箱有所不同,该工具箱不是基于矩阵的数值分析,而是使用字符串来进行符号分析与运算。
In addition, through numerical calculation it was indicated that, under inhomogeneous ground stress, the influence of casing eccentricity on casing load was unnoticeable, but it is still necessary to keep the casing string at the center of the hole as far as possible. 另外,数值计算结果表明,在非均匀地应力条件下,套管偏心对套管应力载荷的影响并不大,但尽量保持套管居中仍是必要的。
