Defining a strict sequence, as in a waterfall model, is just as much a process as defining a semi-ordered sequence of iterations in parallel work.
定义一个严格的序列，比如在瀑布模型中，与在并行工作中定义一个半排序的迭代序列是基本相同的。
Currently there exist several asynchronous measurement fusion algorithms, namely, firstly strict synchronizing sensors asynchronous data and deal with them with parallel or pseudo-sequential filter.
归纳几种多传感器异步量测融合算法，即首先将各传感器异步数据统一到同一时刻，再对该数据进行并行或伪序贯滤波处理。
