改进

This article has mainly studied one kind improved two person two-sided synchronized GTAW craft for the austenite stainless steel. This craft makes the improvement in the original two person two-sided synchronized GTAW craft foundation which one time welding two-sides formings. A series of welding engineer testing on 8 mm SUS304 were carried on. The new craft could guarantee the welding quality in contrast with the original two person two-sided synchronized GTAW.

主要研究了一种改进了的奥氏体不锈钢的双人双面同步钨极氩弧焊工艺，此工艺是在原有的双人双面同步钨极氩弧焊工艺的基础上进行的改进，即将原有的一次焊双面成形改为两次焊成型，并在厚度为8 mm SUS304上进行了一系列焊接工艺试验，验证了这项新工艺与常规双人TIG双面焊相比，能保证焊接质量。

When the number of high accuracy guide stars identified is large, the QUEST algorithm has obvious superiority.According to night-sky observation, based on the guide star flag and the star- Identification information, the selection principle of attitude determination algorithm are given.

四姿态确定算法进行了改进的TRIAD算法和QUEST算法的探讨，这两种定姿算法各有千秋，在识别出的高精度导航星只有2颗的情况下，QUEST算法无法给出姿态，而改进的TRIAD算法可以进行三轴姿态的反演；但在识别出的高精度导航星多的条件下QUEST算法有明显的优势。

To overcome the shortcoming of the double-way authentication access control scheme based on Harns digital signature, a new double-way authentication protocol is proposed to improve the old one. A new single-key-lock-pair access control scheme is proposed as a improved access control scheme, based on the property that a integer can be denoted into only one binary digital.

针对基于Harn数字签名双向认证访问控制实现方案中所存在的问题，运用密码技术改进了原方案的双向认证协议，并作为对原访问控制方案的改进，基于整数二进制表示的唯一性，提出了一种新的单钥-锁对访问控制方案。

Testing reults demonstrate that the economy of equipment and materials as well as the efficiency of work has been improved apparently by our method, as compared with the current me hods.

由于现行的水泥标号检验方法在效率阳经济上有着许多的缺点，本文提出一新方法以改进之，试验结果证明，在经济设备投资和试验材料方面以及工作效率方面，本方法确有一定的改进。

Moreover, we substituted potassium carbonate and Raney Ni for some expensive reagents. We made progress in the basic work of synthesization of ethyl pyruvate p-nitro-phenylthydrazone and indol. Through above improvement, the simple and convenient process with lower costs make it appropriate to be used in the industrial production.

在实验过程中，我们改进了羧酸与仲胺的缩合条件，使产率可达到90％以上，用碳酸钾和Raney Ni或Pd／C代替了昂贵的进口试剂的使用，改进了合成苯腙和吲哚的后处理方法，使整个合成路线的收率提高，成本降低，操作简单，更适合工业化的要求。

In order to overcome the limitations of kernel estimation and shortcomings of the method for determining inliers/outliers threshold in ErrorInVariables model, the projection based Mestimators was improved. First, a new mode search method named adaptive kernel density estimation was proposed. Then, a different strategy was given to determine the inliers.

针对EIV模型中基于投影的M估计方法存在的核密度估计和正常点与异常点阈值确定的局限性，提出一种改进的投影M估计算法：首先给出新的用于搜索极值点的自适应核密度估计函数，然后改进了正常点的确定方法。
