1·Gets or sets a value in the collection by numerical index.
按照数字索引获取或设置集合中的值。
2·Engineering Data, Installation Instructions, Numerical Index.
工程技术参数，安装说明，型号索引。
3·Gets an item from the collection by specifying its numerical index.
借由指定项目的数值索引从集合中取得项目。
4·So, given a sequence named a, you can access elements using a numerical index like a [0] or a slice like a [1:5].
所以，给定一个名为a的序列，就可以使用数字索引(比如a[0])或片段(比如a[1：5])来访问元素。
5·The main innovative points of this thesis are as follows: (1) a new numerical index to score the image scrambling extent is presented.

6·A Ruby hash (or associative array) is a data structure that allows you to define the key for storage (instead of a simple numerical index).
Ruby散列表(或关联数组)是一种数据结构，允许您定义用于存储的键(而不是简单的数值索引)。
7·When parsing the input string into its numerical constituents, we use the hash % idx_for_mon, which holds the numerical index of each month (1.. 12) given its acronym.
当将输入的字符串解析为数字时，我们使用的是哈希表(hash) % idx_for_mon，它保持了每个月份(1 . . 12)给定缩写的数字索引。
8·Experimental results show that the proposed numerical index suits the intuitionistic vision effects perfectly. (2) a new image scrambling method based on BP neural networks is presented.
仿真实验表明：该数值指标能较好地与人的直观视觉效果相适应。(2)提出了一种基于BP神经网络的图像置乱新方法。
