在此，基于泊松过程进行分析，对估测器的适用范围进行了讨论，根据估测结果的偏离值和有效性对估测公式进行参数调整，同时根据估测值的大小不断调整数据源的访问频率和次数，从而使数据源访问模式和估测器互相适应，使估测器在最佳估测范围内获得估测值。

The train positioning technology based on absolute position encoding is proposed. The absolute positions of the rail track are encoded with the m sequence. The biconditional markers placed on the rail track are detected sequentially by the train-borne reader. The exclusive position code consists of the binary information in the shift register. The absolute train positioning information can be extracted by decoding this position code.

利用m序列（最大周期线性反馈移位寄存器序列）对轨道线路上的绝对位置进行编码，当列车在线路上运行时，通过车载阅读器顺序检测设置在轨道线路上的二值标记，在不同位置上读到的标记在移位存储器中构成唯一的位置编码，以此位置编码值作为地址与车载阅读器所处位置的坐标信息相对应，就可以实现列车的绝对定位。

The converter can be improved just by exchanging the position of the resonant inductance and the transformer such that the transformer is connected with the lagging leg. The improved converter has several advantages over its counterpart, e.g., the clamping diodes conduct only once in a switching period, and the resonant inductance current is smaller in zero state, leading to a higher efficiency and reduced duty cycle loss. The operation principle of the improved converter and the comparison with the original converter are analyzed in this paper. The effect of the blocking capacitor in series with the transformer or resonant inductance is discussed, and a best scheme is determined.The improved converter is adopted to design the DC/DC converter of secondary power supply in HVDC power system.

本文将谐振电感和变压器交换位置，使变压器与滞后桥臂相连，这样箝位二极管在一个开关周期中只导通一次，同时零状态时谐振电感电流较小，有利于提高变换效率和减小占空比丢失，本文分析改进后变换器的工作原理，并与改进前的变换器进行对比，讨论隔直电容在不同位置对变换器工作的影响，确定一种最佳工程方案。
