累积误差

By this mean in the mosaicking over large areas, we can ensure the flexibility and efficiency of mosaicking, avoid the middle results and error accumulation, and make the mosaicking results have no relation with the order of images.

采用这样的方式进行大范围的镶嵌可保证处理的灵活性与效率，避免误差的累积和中间结果的产生，且使处理结果与影像的顺序无关。

In order to solve the accumulation of synchronization error over hop distance in large scale wireless sensor networks, A new time synchronization algorithm has been proposed based on two-layer topology.

为了解决大规模无线传感器网络中同步误差随跳距的累积问题，提出一种基于二层拓扑结构的时间同步算法。

According to verifying 11 vacuating wells parameters such as structure and sand body thickness that have been predicted by model, it shows high coincidence rate of more than 90% to real datum. Moreover, the permeability variation in pilot site accords with water flooding situation. The computed parameters such as reserves, cumulative oil production of single well and area, water cut have small relative error of less than 2%, the matching accuracy degree is high.

通过11口抽稀井检验，模型预测的构造、砂厚等参数与实际情况相比，符合率在90%以上；试验区的渗透率变化与水淹状况也具有较好的一致性；储量、区块及单井累积产油量、含水等参数计算的相对误差均小于2.0%，拟合精度高。

Secondly, to reduce the error cumulating effect of LAG-BA, another bit-allocation algorithm was derived from the least square support vector machine, where the coding information of several similar frames was taken into account. The proposed algorithm is denoted least square support vector machine bit allocation, which further depresses the video quality fluctuation.

针对LAG-BA的误差累积效应，根据最小二乘支持向量机的原理，进一步提出了一个考虑到多个相关图像编码信息的目标比特估计算法，并用LAG-BA和LSSVM-BA取代MPEG-4 Q2方案中的比特分配算法设计了两个改进的MPEG-4 Q2方案。

The error of inertial navigation systems is cumulated in course of time because of the drift of the measurement unit-gyroscope. Using the celestial navigation system and the information processing technology, the paper disscusses the INS/CNS integrated navigation systems.

惯性导航系统由于其感测元件—陀螺仪的漂移造成导航系统误差随时间不断累积，本文利用天文导航系统，结合信息处理技术，探讨了惯性/天文组合导航系统的相关问题。
