The results also show that subtituent position on the benzene ring has a great influence on the transfer volume. The trends of change of δ〓ΔΦ〓〓 for mand p-isometers with the composition of the mixed solvent are similar. However, the position and amplitude of the limit valve are different from each other. These are discussed according to the inductive effect and the resonance effect.

研究发现：取代基在苯环上的取代位置对迁移偏摩尔体积有明显影响，间、对位取代的异构体在DMF-水混合溶剂中的δ〓Δφ〓〓随混合溶剂的组成变化规律相似，但极值点的位置及幅度有所不同，根据诱导效应和共轭效应对此进行了讨论。

The story of these stamps began on may 14,1918,the day after they were placed on sale.in washington,d.c.,w.t.robey,a man interested in stamps,decided to buy a sheet of the new stamps and so went to the new york avenue branch post office in washington.when the clerk handed him a sheet of the stamps robey noted that they were poorly centered.he looked at other sheets and found that none was well centered.the clerk asked robey to return later in the day when more stamps were expected.

关于这些邮票的故事发生在1918年5月14日，该日是它们开始销售的第二天。在首都华盛顿，一个集邮爱好者，罗比，决定去买一整版新邮票，于是他来到华盛顿市纽约大街的邮政支局。当职员递给他一版新邮票时，罗比看到它们的中心位置很差。他看了其它几版，没有一个摆正中心位置。职员告诉罗比当天晚些时候来退换，估计那时有更多邮票到货。

In this design, according to the principle of crank-rocker, a special four-bar linkage swaying mechanism combined with the flexible tail fin is adopted to guarantee the stable swimming of robofish. The skillful application of hall position sensors achieves the detection of critical position of the swing link, which makes it possible to detect the position of the tail fin and control the turning of robofish. For effective raising and lowering, a mechanism using a cylinder as a pump to imitate the swimming bladder is developed.

在该方案中，应用曲柄摇杆原理，采用了特殊的四连杆摆动机构，结合柔性尾部实现了机器鱼的摆动式推进；巧妙应用了霍尔位置传感器，检测摆杆临界位置，实现了鱼尾位置判断，进而控制鱼尾来转向；研制了以气缸为压缩泵的气路沉浮机构作为&鱼鳔&，能使机器鱼进行沉浮动作。

The distribution of spark locations corresponding to certain potential differences are simulated numerically, which shows that it is unable to detect the definite spark location with two inputs.

四点输入情况下理论和仿真研究了放电点位置与电位差对V〓-V〓和V〓-V〓的关系，从而证明了四点输入可以唯一地检测出放电点位置；通过研究四点输入和三点输入的圆电极的情况，首次提出可以将放电点位置检测的电位差法推广到其它形状规则对称的电极上。

Based on the distance of two common joint between the basis four-bar and the dyad that a Stephenson six-bar chain contains, the theory and method to identify the circuits of Stephenson six-bar chain are presented.

在机构的精确点位置综合中，如果其设计位置位于不同的回路，那么机构必须重新装配才能实现设计位置的运动，则说机构存在回路缺陷，在实际中这种机构是无用的12一'2。

When an identifier indicating the apparatus side power delivery/reception section is present in the vicinity of the target parking position in the imaged surrounding situation, the controller (60) recognizes the position of the identifier and performs the alignment assistance control.

当标识设备侧电力发送/接收单元的标识器在所拍摄的周围情况中位于目标停车位置附近时，控制装置(60)识别出标识器的位置，并进行位置对准辅助控制。

We also used the latent heat daily data、sensible heat daily data、relative humidity data and OLR daily data from NCEP-DOE Reanalysis2 which formed as 2.5-degree latitude x 2.5-degree longitude global grid with 144x73 points(1982～2005). The data of subtropic high ridge offered by Bational Climate Center . With singular value decomposition analysis, we studied key region of ocean-atmosphere interaction in the mid-latitudes in the Pacific. Second, by using wavelet analysis to study the character of the key regions of SST.Moreover the correlation analysis can help us to understand the reason of the cold water formed and the physical process of ocean-atmosphere interaction in the mid-latitudes in the Pacific. There are three mostly SVD modes which contribution reach to 70%,So the three mostly modes can reflect the mostly structure in the key region.

采用奇异值分解方法对1982～2005年逐候SSTA场和500hPa位势高度场进行同期、大气超前海洋、大气滞后海洋的分析，确定中纬度西北太平洋海气相互作用的关键区；利用小波分析对关键区海温和副高脊线进行周期分析，深入了解研究区域海温和副高脊线的年际、年代际变化特征；通过关键区海温与500hPa位势高度距平场的相关分析，研究中纬度西北太平洋SST异常与副高位置异常的关系；针对2005年夏季关键区SST异常与副高脊线位置异常开展海气相互作用物理量分析和大气环流分析，探讨关键区SST异常对副高位置异常的可能影响过程。
