In 1965, the Bilderbergers met again. George Adamski takes motion pictures of an object at Silver Spring, Maryland on February 26, 1965. On March 18, the Soviets give a less than adequate performance during the "spacewalk" of Leonov. Its obviously a staged event not taking place in space. In June, astronaut James McDivitt sees an object in space and reports it.

1965年，Bilderbergers再次开会。2月26日﹐乔治亚当斯基乔治亚当斯基在马里兰州银泉拍到了飞碟影片。3月18日，苏联Leonov的"太空漫步"显然不是发生在太空。6月，宇航员詹姆斯麦克迪维特看到太空中的一个物体﹐并且上了报告。

Through assessment, it can be concluded that the water quality in Shuimo river valley of Urumqi was worse; the water quality did not improve in last three years, and this trend was not stable either in space or in time; the water quality was best in low water period but it's worse in flush water period and slack water period; in space the water quality in Tangcichangquan section was best , it's the second place in Qifangqiao section and Lianfengqiao section while it's worst in Miquanqiao section. According to the analysis, the trend of the water quality change of Shuimo river valley of the major pollutants, the method of Spearman was used in 1996 to 2002. It concluded, the pollutants did not have the remarkable trend of change in Tangcichangquan section,but BOD5 had very prominent raising trend in Qifangqiao section, so did BOD5, petroleum, and ammoniac nitrogen in Lianfengqiao, DO in Miquanqiao section in seven years.

根据秩相关系数法对水磨河流域1996 -2002 年主要污染物变化趋势分析，搪瓷厂泉断面作为流域的源头，各污染物七年里没有显著的上升或下降趋势；七纺桥断面的五日生化需氧量在七年中有很显著的升高趋势；联丰桥断面的五日生化需氧量、氨氮、石油类在七年里都有非常显著的升高趋势； DO 在米泉桥断面七年里也有非常显著的升高趋势，后三个断面接受了沿岸工矿企业的生产废水和周边居民的生活污水，水质明显变差，每个断面污染源不同，占主导地位的污染物也有差异。

Widening of the cricothyroid space in 15 cases (68.2%); 4. thyroid cartilage destruction in 12 cases (54.5%); 5. lymph node metastasis in 16 cases (72.7%). Mass effect from bulky pyriform sinus tumor distorted the adjacent normal structures, simulating tumor involvement in some instances and causing 8 false positive CT findings in our study.

综合主要的CT表徵包括：(1)扩展到喉外软组织有16例(72.7%)；(2)蔓延至会厌前空间(pre-epiglottic space)有12例(54.5%)，但只有3例越过中线；(3)环状甲状软骨空间变宽有15例(68.2%)；(4)甲状软骨被侵蚀破坏有12例(54.5%)和(5)淋巴结的转移有16例(72.7%)。

In the sense-representation of external things, the quality of space in which we intuite them is the merely subjective side of my representation of them (by which what the things are in themselves as objects is left quite open), and it is on account of that reference that the object in being intuited in space is also thought merely as phenomenon.

在我们感知外物的表象时，我们在这个空间中（也就是我们得以直观外物的空间）所获得的感受是全然主观的（而物体的真相在此则维持一个非常开放的状态），也就是因为这样主观的指涉，被我们在空间中所直观的客体才会被认为只不过是一种「现象」。

The above problems are studied in this thesis. First, the implicit NND scheme with mix flux splitting method proposed by Zhang Hanxin that is first order accurate in time and second order in space is modified. The modified scheme keeps the characteristics of fast convergence and is second order accurate both in time and space. It can be capable of simulating the unsteacly flow. Second, the topological method founded by Zhang Hanxin is improved to study the characteristics of vortex near the singular point on its axis and the cross streamlines on the longitudinal section passing the vortex axis. On the basis of topological results, a program which visualises numerical results is made out. It can help us analyse the characteristics of vortex motion.

本文对上述问题做了研究：第一，在数值模拟方面，借助于张涵信提出的NND算法和混合通量法，我们将他建立的时间为一阶、空间为二阶精度的快速隐式算法推广为时间和空间均为二阶精度的算法，这样做保留了原格式收敛快的特点，而且能适用于真实的非定常流态的计算；第二，将张涵信的拓扑分析方法加以推广，研究了涡轴附近及破裂点邻域内流场的空间特征，并以这些拓扑分析结果为指导，研制了一套显示计算结果的软件，这一软件能很好地帮助我们分析流场的计算结果和旋涡演变的特征。
