The phylogeny and applied prospect of MES are summarized in the paper. The principle of this system is analyzed from the point of view of acoustics. The surveying and filtering technology of auxiliary parameters, sounding data and the theory of image form, backscatter strength data processing, are researched deeply in the paper. The optimal model of velocity of sound is given. For sound ray tracing, some methods of correction of sound ray curve are developed. At the same time, an ideal model of sound ray tracing is proved and given. The GPS technology is applied for the determination of tide, attitude of vessel. Moreover, some methods are given. As an important topic, the systematic error is discussed in the paper. Some filtering methods are researched in this paper. Based on the current methods of image processing, the procedure and methods are tested and given that adapt to sonar image processing.

本文研究的工作是在总结多波束声纳测深系统的发展历史、应用前景的基础上，从声学角度分析了多波束系统的工作原理；对多波束辅助参数的测定和滤波方法、测深数据的滤波方法、多波束声纳图像的形成机理、图像处理以及最终应用等作了比较深入的研究；得出了适合于多波束精密深度计算的最优声速模型和声线改正模型；提出了 GPS 载波相位定位技术用于多波束辅助参数测量的思想、算法，改善了多波束系统的作业模式；系统地分析了深度数据的误差来源和类型，首次将系统误差作为影响测深精度的主要因素给以研究，并给出了削弱系统误差的方法，提高了深度数据的质量；对多波束声纳图像的形成、处理方法进行了细致的研究，给出了适合多波束图像处理的算法和流程，并从理论和实践上对声纳图像的应用进行了比较全面的研究。

The results showed that: at metaphase I, the homoeologous chromosome pairing among different F1 hybrids ranged from 2.0 to 11.4 bi-valents formed by homoeologous chromosomes per pollen mother cell, and very few multivalents, and even very few bivalents were formed by two chromosomes within one genome rather than homoeologous chromosomes in some PMCs; at anaphase I, all biva-lents were disjoined and most univalents were divided.

结果表明在中期I阶段，这些杂种一代的近缘染色体联会变化很大，每个花粉母细胞中二价体形成的数目从平均2个到11.4个不等，甚至在某些花粉母细胞中，还发现极少的多价体和非部分同源染色体所形成的单基因组内二价体；在后期I时，所有的二价体分离，同时多数单价体也分离，分离的二价体和分离的单价体都移向两极，从而形成两组染色体；因为这时完整花粉母细胞中分离的二价体在两组染色体中总是对应出现，从而根据半二价体上染色体重组的位置可以分析在二价体的四分体时期发生在非姊妹染色体之间的多种染色体交换类型，如单交换、三线双交换、四线双交换、四线三交换和四线多交换。

Fitted to the exposed spindle was a unique "screw-cutting dog clutch" that, the makers claimed, allowed " even those without previous experience cut any thread easily and quickly "- if only the generation of good-quality threads were so simple; however, in the sense that it was impossible to "pick up" a thread at the wrong point and spoil a job, the device did work efficiently - and was well received by experts at the time (the headstock was considered well enough engineered to be adopted as the basis for an ingenious multi-function machine tool the " Metalmaster "- the details of which make fascinating reading).

安装在暴露主轴是一个独特的&螺旋切割狗离合器&这一点，制造商声称，允许&，甚至那些没有以往的经验削减任何线程轻松和快速地&-如果只产生高质量线程是如此简单的；然而，在这个意义上讲，是不可能的&拿起&一个线程在错误的点和破坏工作，该设备也提高工作效率-，并且受到专家们的时间（在启闭被认为不够好工程要通过为基础，设计精巧的多功能机床的& Metalmaster &-的细节，这使得迷人读）。

Results The morbidity of pneumonia in the elderly in Shenzhn was high（60.8%）,the symptoms of respiratory system were atypical and those of the digestive system or the nervous sysˉtem may be the main features;the chest X-ray inspection mainly showed the features of Bronchopneumonia;the comˉplications were multiple.

对102例老年肺炎的发病情况、临床表现、实验室检查及胸部X线结果进行分析。结果深圳地区老年肺炎夏季发病率高（60.8%）；呼吸系统症状不典型，可以消化道、神经系统症状为主要表现；胸部X线主要表现为支气管肺炎；合并症及并发症较多。

Ethernet inter-working model based on pseudo wire in T-MPLS layer network;2. However,traditional LDP based VPLS can not be deployed in large-scale networks due to the full mesh connection problem of pseudo wire .

它的主要思想是在MPLS网络中利用LDP建立和维护以太网伪线，并基于伪线将多个局域网两两互连成一个VPLS网络。

Moreover, in the machine pit for wheel repair, often in the welding process, weld quality, especially for Type-ray examination of the negligence or difficult to meet the standards, the result is the repair more times a deviation from the correct line of blade farther lead to more repair performance worse, damage increased.

更有甚者，在机坑内进行转轮修复，往往在焊接工艺、焊缝质量，特别是对型线检查的疏忽或难以达到标准，结果是修复次数越多，偏离正确叶片型线越远，导致性能越修越差，破坏加剧。
