选择值

If N is inexactly representable, t is required to be one of the two adjacents, with an implementation-defined choice of rounding direction; that is, the conversion is required to be correctly rounded.

如果 N 是不可精确表示的，则要求 t 是两个邻值之一，舍入的方向由实现定义来选择；即要求转换是适当舍入的。

The following conclusions have been reached, milk has an obvious absorption in the mid-infrared band, and the locations of the absorption peak are consistent with the attributes of molecule functional group analysis and the information from FOSS Company; the effects of the factors on the repeatability are below 3‰; For the quantitative analysis, the method of factorial design is applied to optimize the calibration set. The outliers are determined considering the residual variance distribution. The correlations are 0.990 and 0.986 for fat and protein, respectively. The Root Mean of Square Error of Prediction is 0.121 and 0.111 for fat and protein, respectively. With the application of the methods of wavelengths selection, the numbers of wavelength is decreased greatly from 3301 to 100. The speed is accelerated and the accuracy of the calibration is improved to some extent.

结果表明：牛奶在中红外的吸收特性明显，吸收峰的位置与分子结构的谱带归属以及乳品分析仪器的成功厂商FOSS公司提供的资料基本一致；各种因素对光谱测量影响的CV值基本可以控制在3‰以下；在定量检测中，通过析因设计方法优选校正集样品，结合样品的残差图确定奇异点，脂肪模型和蛋白模型的相关系数分别为0.990和0.986，预测均方根误差分别为0.121和0.111，而在采用波长选择对模型进行优化后，波长从3301个减为100个以内，加快了运算的速度，同时还在一定程度上提高了模型的精度。

The choice of a suitable value for the factor of safety also presents great difficulties.

选择适当的安全系数值也存在大的困难。

Hierarchical linear modeling is the most frequently used technique for analyzing multilevel data. In this paper, the twelve key issues in multilevel research and/or using HLM software were reviewed, and provided their exact meanings and feasible solutions. The 12 key issues included intraclass correlation coefficient, sample sizes, formation of organizational constructs, centering problems, fixed effect and random effect, estimation methods, goodness of fit index, explained variation, multicollinearity, robust standard error, level one variance equation, and empirical Bayes estimates.

Displayed values, choice of engineering units and 12 characters of user programmable text can be printed directly from the IBM/Epson compatible serial printer port.

8226；显示的值，选择的工程单位和12个字符的用户可编程的文字可以直接打印从IBM /爱普生兼容串行打印机端口。

This circuit is more simple, convenient connectivity, the choice of its parameters with the speaker impedance has a direct relationship, and the speaker impedance is a function of frequency, with larger deviation from the nominal value, so the error is also large, is not conducive to adjust.

此电路较为简单，连接方便，它参数的选择与扬声器阻抗有直接的关系，而扬声器的阻抗又是频率的函数，与标称值偏离较大，因此误差也大，不利于调整。

By using the exist- ence result of VF- ICP and VF - IVIP with single - valued mappings and the continuous selection theorem due to Ding,Kim and Tan, solution existence for GVF- ICP and GVF- IVIP is derived under suitable assumptions.

通过具单值映象的向量F-隐补问题和向量F-隐变分不等式问题解的存在性的研究和使用Ding，Kim和Tan的连续选择定理，在适当假设下证明了CVF-ICP和GVF-IVIP解的存在性，推广了其他人的结果。
