1·According to weight coefficient of binary variable, discrete variables can be gradually determined in optimization process, and their discretization can be realized during iteration successively.

并且，在优化过程中根据二进制变量的权重系数逐步确定离散变量的取值，实现了离散变量在优化过程中的逐次归整。

2·Authentication providers may allow reading user identity information from an environment variable or some binary token.

身份验证提供者可能允许从环境变量或某个二进制令牌读取用户身份信息。

3·Create a shell variable called cc whose value is the full path file name to the GCC binary.

创建一个shell变量cc，它的值是gcc二进制代码的完整路径文件名。

4·On Windows, you should also set the PHP_EXECUTABLE variable, which defines the complete disk path to the PHP binary. Here's an example.

对于Windows系统，您也应该设置PHP_EXECUTABLE变量，该变量定义到php二进制文件的完整磁盘路径。

5·DIGITAL-TO-ANALOG, the process of converting a digital signal (binary) to a continuously variable (analog) signal that is a close approximation of the original signal.

数一模转换，将数字信号(二进制)转换成与原信号相似的连续可变(模拟)信号的处理过程。

6·Ordered binary decision diagrams(OBDDs)are a data structure for efficient representation and manipulation of Boolean functions. The size of OBDDs is very sensitive to variable ordering.

有序二叉决策图（OBDD）是一种有效表示布尔函数的数据结构，其大小依赖于所采用的变量序。

7·The nonlinear response in the bistable system with a random binary signal by adding the variable amount of noise is studied, and the input-output cross-correlation coefficient is measured.

研究了噪声和随机二进制信号同时激励双稳系统时的输出响应，并测量了输入输出互相关系数。

8·Such dilemmas might be pondered one day by future humans living on a planet orbiting a cataclysmic variable binary star system.

这可能是当未来人们居住的行星，运转于一个激变星的双星系统下所需要担忧的事情。
