Any site was subtracted of analysis errors from the raingauge network and the influence of the missing data on estimating average rainfall is evaluated 而重覆法则用以评估雨量测站对平均雨量推估之影响程度。
Ann methods are feasible for the verification measurements in nuclear safeguards . experimental data sets have been used to study the performance of neural networks involving radial basis function neural network and generalized regression neural network ( grnn ) . the optimization of the parameter spreads have been given and the analysis error of grnn no more than 0 . 2 % 分析结果表明,使用泛化能力较高的混合训练集训练神经网络,网络给出的富集度值与标准样品的标称值之间的相对差异小于13 % ;使用泛化能力相对较弱的分组训练集训练神经网络,网络给出的分析结果的不确定度小于2 % ;使用分组训练集和广义回归神经网络,网络给出的分析结果的不确定度小于0
This article introduces the application of area ccd in untouched measurement of industry , clarifies structure of untouched measuring system and problem needed to resolve in the industry environment , and also gives scheme , structure of system , design of optical system and software in automatic sort systems of substrate by area ccd , by comparing different algorithms of filter , edge detection , subpixel , analysises error of hardware system and algorithm , the best one which can get high accuracy and speed in practice is obtained 本文介绍了面阵ccd在工业非接触测量中的应用,阐明了面阵ccd工业非接触测量系统的组成及工业应用中需解决的问题,说明了面阵ccd基片分类机测量系统的方案选择、系统组成、光学系统设计及测量的软件系统,并针对其生产应用详细分析了它的硬件系统误差及软件算法,比较选择了滤波、边缘检测、像素细分的算法以控制系统的精度与速度。
The test of " xx " underwater to surface missile aiming precision was tested on the sea . under the circumstance there was no reference information about domestic and overseas , the test of the underwater to surface missile aiming precision for the first time was finished on the mobile bedding launching , and filled up field of aiming spacing in our country . the test indicated that total precision of missile aiming system and analysis error of drop into target provided the foundation 基于外测岸标的“ xx ”潜地导弹海上瞄准精度鉴定试验,它是在无国内外参基于外测岸标的潜地导弹瞄准精度鉴定方法研究外参考资料可借鉴的情况下,我国首次在动基座上进行潜地导弹瞄准精度鉴定试验,填补了我国在这一领域的试验方法及试验技术的空白,取得的试验结果,对于分析导弹落点误差及估算导弹组合命中精度提供了依据。
