In so doing, we expected to obtain the information regarding particle size and size distribution of AuNPs directly from the electrophoresis results. In this experiment we used 10mM Sodium tetraborate and 10mM Sodium phosphate containing 200mM Sodium dodecyl sulfate as electrophoretic run buffers (pH 8.8), and AuNP Standards were treated with the synthesized compound hexyl-oligo(p-phenyleneethyny-lene)-poly as the sample and separated by CE.

根据电泳最佳条件的实验结果，我们采用10mM Sodium tetraborate与10mM Sodium phosphate并添加200mM Sodium dodecyl sulfate作为缓冲溶液（pH 8.8），以经实验室合成的界面活性剂（hexyl-oligo (p-phenyleneethyny-lene)-poly，Hex-OPE-PEO）修饰过后的金奈米粒子标准品作为样品进行电泳实验，将所测得的电泳迁移率与标准品颗粒大小做一校正曲线，可以得到最佳的电泳迁移率－粒径大小之线性关系（R2＞0.99）。

To compensate the magnetic deviation produced by the soft iron and hard iron distortion in attitude and heading reference system, a recursive least square algorithm using continuous magnet field information was developed.

为校正姿态与航向参考系统使用环境中软硬铁产生的罗差，提出了一种利用地磁场连续转动信息补偿三轴软硬铁的方法。

Results Uncertainty in the calibration curve and standard solution concentration were the main source of uncertainty in sample measurement.

Firstly,surd or sonant judgment with each voice frame is done,then the multi-scale wavelet analysis is done only on the sonant frames to get pitches.In order to get accurate pitches,the intervals of local modulus maxima of dyadic wavelet coefficients are corrected according to amplitude information and appearance probability information.

针对这一问题，提出一种基于小波变换的基音周期提取改进算法，将TEO算子与二进小波变换结合起来，首先进行清浊判定，然后只对浊音帧采取多尺度小波分析提取周期，提出用幅度信息和出现概率信息校正二进小波模极大值间距，从而得到准确的周期。
