大尺度

By using of NCAR/NCEP reanalysis daily average data from 1950 to 2002 and daily rainfall of 355 stations in east China from 1957 to 2000 , whole layer vapor transportation fluxes of all globe are calculated , climatic characters of East-Asia pentadactyl vapor transportation in summer are analysed , differences of pentadactyl vapor transportation in strong vapor transportation years and short ones , and relations of vapor transportation in East-Asia and rainfall in east China.

使用1950～2002年NCAR/NCEP再分析逐日平均资料和1957～2000年我国东部355个站点的逐日降水量资料，计算了全球整层水汽输送通量，分析了东亚地区大尺度候平均水汽输送时空分布的气候特征和年际、年代际变化特征，研究了水汽输送强、弱年候平均水汽输送的差异，讨论了东亚地区各候水汽输送与我国东部降水的关系。

This resuit may be related to differences in selection pressure exerted on species by their habitats with different distribution ranges.

说明在大尺度上遗传距离与地理距离相关而在小范围内则无上述关系，该结果可能与位于不同分布区内的物种所承受的生境选择压力不同有关。

However, using the structure of a solid to determine the stereochemical structure of a polymer has not been satisfactorily achieved.

该方法如果扩展到更大尺度，有可能帮助将具有精确结构的聚合物用在一系列技术应用中。

This suggests the incomplete welding of the sides of the fault by the granitic intrusion along it,which afterwards permitted the reactivation of the fault,probably due to the relatively independent movement of the faulted blocks,as a dextral transcurrent fault.

这意味着稍早的花岗岩侵入体冷凝冷却并没有完全焊接地壳内一些大尺度断层，地壳断块的相对独立活动可以造成沿着这些断层发生与区域变形场不协调的右行走向滑动，进而形成岩墙群弧形展布所需要的地应力场。

The numerical results show that:(1) the throughflow wake is considerably influenced by the tip clearance. The low-kinetic-energy fluid accumulated in the shroud/pressure side of the unshrouded impeller, but in the shroud/suction region for 0.0 tip clearance;(2) there possibly exists an optimum size of the tip-clearance which is not the zero tip clearance to make the flow loss minimized.

研究结果表明，(1)NASA低速大尺度离心压缩机半开式叶轮的低速尾迹区在压力面与轮盖的角区，而相应的闭式叶轮的低速尾迹区聚集在轮盖的中心位置；(2)数值实验表明，叶顶间隙并非越小越好，可能存在一个最优间隙，使得叶轮流动损失最小。

According to calculated results of this"System",three major rich areas of "large scale" unswept remaining oil in waterflooded bedded sandstone reservoirs have been determined:1.the unswept remaining oil in top of waterflooded positive rhythm reservoire with high viscosity oil;2.the unswept remaining oil in side parts and corners of oil reservoirs;3.the unswept remaining owing to development of non-proportionably each substratums in a series of strata.

利用抽象地质模型及相应的典型油层参数加油藏数值模拟加油藏工程加数理统计的研究方法，研究出了&注水多层油藏小层层内与平面波及评价系统&，利用这个系统的计算，确定出了注水多层油藏&大尺度&未波及剩余油的三大富集区：①注水高粘正韵律油层顶部未波及剩余油；②边角影响未波及剩余油；③层系内由于各小层物性差异开采不均衡形成的未波及剩余油。

This paper studies numerically the influence of the tip clearance on the three-dimensional viscous flowfield and performance of the NASA Low-Speed Centrifugal Compressor impeller with a vaneless diffuser. A three-dimensional viscous code developed by the authors is applied with several acceleration methods: local time-step, multigrid and residual smoothing.

通过求解N-S方程，数值研究了叶顶间隙对NASA低速大尺度离心压缩机三维粘性流场及气动性能的影响，在计算程序中采用了当地时间步长、多重网格以及隐式参差光顺来进行加速。

After the region dividing, accumulation temperature has decreased correlation with latitude and increased correlation with altitude in most accumulation temperature region. This indicates that the latitude zonality of accumulation temperature is , to some degree, demolished when the study area dwindles. At the same time, the vertical zonality caused by microscale terrain is better revealed.

分区后，积温与纬度的相关性在大部分积温区中有所下降，与海拔高度的相关性大部分呈上升趋势，这说明研究区域的缩小一定程度上破坏了相对大尺度的积温纬度地带性，而更好地表现出了由小地形导致的垂直地带性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
