变量范围

A DPLS discriminant analysis model was developed based on spectra region from 400 nm to 2 498 nm with mathematic pretreatment 2-8-6-1 and scatter correction treatment the standard normal variate. The accurate discriminant rate of calibration and external validation was 95.7% and 95.6% respectively. For the adulterated samples (MBM mass percentage≥5%), the accurate discriminant rate was 100%.

建立的判别分析模型：数学预处理方法为2-8-6-1，散射校正方法为变量标准化处理，光谱范围为全谱（408～ 2 492 nm），定标模型的正确判断率为95.7%，外部验证正确判断率为95.6%，对于掺入量≥5%MBM时，正确判断率为100%。

The NIRS quantitative analysis model was developed for measuring MBM content in fish meal by using partial least squares. The initial spectrum was pretreated by standard normalized variate, 7 point smoothind and one derivative respectively.

应用偏最小二乘定标方法，在8 678.10~4 250.34cm^(-1)波数范围内，采用变量标准化、7点平滑和一阶导数对光谱进行预处理，建立了鱼粉中肉骨粉含量的NIRS定量分析模型。

To divide the range of a variable into a finite number of non-overlapping intervals that are not necessarily of equal width, and to designate each interval by an assigned value within the interval, e.g., a person's age is for most purposes quantized with a quantum of one year.

把一个变量的取值范围分成有限个不重叠的区间，这些区间的大小不一定相等，并给每个区间指定一个属于该区间内的值。例如，人的年龄在大部分情况下是用一年这个量［区间］来量化的。

We do not find this extreme forecast credible; when the independent variable has moved so far from the historically observed range, we cannot trust a linear regression line.

当独立的变量离开历史上观察到的范围如此之远，我们无法相信一个线性回归。

The revised simplex method is used at first to calculate the optimal line extensions without integer constraints of the variables so that it can be determined which lines should be constructed.

第一步不考虑变量的整数约束，用修正单纯形法求解，由此可确定一部分线路是否需要建设。第二步在缩小的可选线路范围内进行整数规划计算，从而快速形成电网发展方案。

The model of leachate head dynamic variation in recirculation is developed and the model is solved by solution of separation variables.

建立了回灌条件下垃圾渗滤液水头动态变化的模型，并用分离变量法对该模型进行了解析求解，对解进行了分析讨论，分析结果表明：水头的变化趋势大致为一抛物线，在抛物线顶点处达到最大，在一定的时间范围内，时间越长，其压力水头变化越明显。
