The details are as followings : the most usual problems related to navigation data fusion are studied ( the local navigation sensors export directly navigation parameters and their accuracies without feedbacks and cross data communications ) ; a novel conservative optimal fusion method of non - feedback multi - source correlated estimators is presented , and this method is extended to the case of more than two data sources ; some new theorems are supplied or proved so that our methods are naturally connected to the achievements up to present , and the integrated theory basis of non - feedback multi - source correlated estimators fusion is founded 具体内容如下：研究了最一般的导航数据融合问题(局部导航仪直接输出导航参数及精度，且无反馈、无局部导航仪之间的交叉数据通讯) ；提出了一种新的无反馈多源相关估计向量的保守最优融合算法，并将该算法由两个数据源推广到了多个数据源；补充证明了一系列定理，从而将本文方法和前人研究成果有机地融为一体，建立了完整的无反馈多源相关估计向量融合的理论体系。
You typically accomplish this by calling the update method of the same tableadapter or data adapter that you used to populate the dataset , although you can also use different adapters , for example , to move data from one data source to another or to update multiple data sources 为了完成这一步骤，您通常会调用曾用来填充数据集的同一个tableadapter （或数据适配器）的update方法（虽然您也可以使用不同的适配器，例如为了将数据从一个数据源移动到另一个数据源或更新多个数据源） 。
