查询词典 calibration

A two-component carbon tetrachloride system and a two-component aqueous system have been treated with the proposed strategy where only 21 calibration samples are needed, and the result showed that the predictive ability was not obviously impaired for the former system while being clearly strengthened for the latter one in comparison with a conventional way that required a calibration set of 100 samples.5 An unlooked-for experimental observation that in near-infrared spectroscopy the second overtone of aniline adsorbed by 13X molecular sieve nearly disappeared led us investigate a fundamental problem: the behavior of NIR when the outside space surrounding a molecule is too small to allow the molecule to vibrate freely.

同时，最小相关样本设计能进一步减少所需的校正样本数，且能提供更多合适变量以建立多元校正模型。这两方面的改进使模型的预测能力得以提高，其预测精度即使在水体系中也有明显的改善。五、近红外漫反射光谱在线非接触监测气-固吸附过程中出现了一个意外现象，即在近红外光谱上，被13X分子筛吸附的苯胺的二级倍频几乎完全消失了。这促使笔者深入探讨了近红外光谱的空间效应(当一分子被一足够小的刚性空间限制时，其振动的受限导致一级倍频和二级倍频强度均减少，并且后者减少的程度比前者更大)。

The representiveness of training samples for multivariate calibration has been discussed and the concept of weighted sampling has been introduced to multivariate calibration.

By formulating the apparent porosity cross calibration model of these two logs, and adopting the same matrix logging pa rameters as those of the practical complex lithology, the study constructs new log curves, utilizes and amplifies the different responses of neutron and density logs, eliminates multiple solutions caused by inaccurate calibration lithology, makes the overlayed curves take the same units, greatly improves the gas-i dentification resolution of this combination, intensifies the visual effect of gas indication.

从而能够放大中子、密度测井对地层中天然气的不同响应，消除刻度岩性不准确产生的多解性，统一重叠曲线的量纲，大大提高这两种测井组合识别气层的分辨率，增强气层指示的直观性。

Aim at the question of measurement inaccurateness for the causes of disturbances and temperature excursion in the PLC multi-analog signals measure system,a kind of analog calibration method least square algorithm based is put forward.And then the detailed computation process of PLC analog signal's measure calibration is provided.

在由传感器、隔离器和PLC模拟量测量模块以及后端显示计算机组成的多路测量系统中，如果对测量参数不进行标定，则由于仪器本身的测量误差、多路测量通路之间的干扰等因素，后端测量计算机显示的测试数据往往是不准确的。

These two calibration methods were compared with numeric experiments. Results indicate that comparing with MSDM, BDM is not only available for the force calibration of non-spherical or anisotropic cells, but also for irregular cells in optical trap potential with inharmonic and asymmetric profiles. The results agree with the experiments reported.

用数字实验对这两种标定方法进行了比较，结果表明：与均方位移法相比，玻尔兹曼统计法不仅适用于各向异性非球性细胞，也适用于非简谐、非对称光势阱中任意形状的生物细胞光阱力的标定，结论与已有直接实验相符。
