大尺度

Another limitation in the original MSG plasticity theory is the assumption of infinitesimal deformation.

针对原有的 MSG 理论中小变形的假设，但是很多问题，尤其是材料的破坏问题，如断裂、剪切带等问题，都涉及到大变形；另外在微电子器件中，例如微尺度的传感器，在应用中都涉及到大变形，为了使 MSG 理论能应用于以上提到的种种实际工程情况，非常有必要发展大变形理论。

Starting from a barotropic model equations including large-scale orography,friction and heat factor,by means of scale analysis and small parameter method,then a barotropic quasi-geostrophic model with large-scale orography,friction and heating is obtained.

从包含大地形、摩擦及加热作用的正压模式方程组出发，通过尺度分析、小参数展开和线性化等方法，导出一个含大地形、摩擦及加热作用的准地转正压模式。

Most species' populations were decline in last fifty years, especially since the last 1980's, the populations such as Alpine Musk Deer, Przewalski's Gazelle and Red Deer etc. declined dramatically;(5) Desertification and grassland degredation are obviously affected by climate change on macrographic scale, anthropogenic activities is an important driving role for desertification, herbing, land-development and urbanization have majority impact to biodiversity spatial pattern and its loss.

祁连山区动物资源组成成分复杂，总体上缺乏自身特有的种类，哺乳动物区系特点不很突出，既包含了东部黄土高原和东南湿润地区的兽类成分，又不乏青藏高原特有种类，同时还与新疆的动物区系有一定的联系，近50年来尤其自上个世纪80年代以来，多数种类的种群数量呈下降趋势，其中以马麝、普氏原羚、马鹿等物种的数量下降的最为显著；（5）土地沙漠化和草地退化在宏观尺度上受气候因素影响较大，人类活动对荒漠化的加速发展起着重要的驱动作用，尤其是放牧、土地开发和城镇化建设对生物多样性资源减少以及空间分布格局影响较大。

Secondly, the author has researched the wavelet coefficients distribution property based on the histgram of detail subimages, and proposed an adaptive image quantization algorithm according to local data distribution in every subimage. In this quantization procession, every subimage will be disparted to some sub-blocks, and the sub-blocks will be quantized with different quantizer according the coefficients distribution; when the bias is large, the sub-block will be quantized with high accuracy; when the bias is little, the sub-block will be quantized coarsely.

其次，作者通过对小波高频子带图像系数分布直方图的分析研究，根据高频子带图像中绝大多数系数的幅度很小、幅度大的系数出现的几率很小的特点，提出了一种基于子带图像局部数据分布特征的自适应量化算法：先把高频子带图像分成较小尺度子块，子块系数离散性越大，采用精度越高的量化器：子块系数分布越集中，使用精度较低的量化器。

Prognosticated dimensions to investigate from the period of year, the overground amount of organic carbon on unit area is big, the underground soil organic carbon on unit area is biger.So,Tamarix is one of important carbon sink at arid land.

从年周期观测尺度来考察，单位柽柳林面积中的碳蓄积量较大，林下土壤中的碳蓄积量更大，因此，柽柳是干旱区重要碳汇之一。

The family hall relative living room says, not only has the privacy, also has a broader comfortable criterion, this and our country housing likes the living room doing very much in a big way, but uses every day the space actually designs very much slightly has the very big difference.

家庭厅相对客厅而言，不仅更具有私密性，也有着更宽阔舒适的尺度，这点与我国住宅喜欢把客厅做得很大，而每天自己用的空间却设计得很小有着很大的区别。

They all require an enormous number of scales to construct the curvature scale space image.

根据这些方法，构建曲率尺度空间所需尺度太大。

In general, take estimations would use global scale GCMs data but too rough-cut for estimating a smaller region, such a stream area.

一般用於评估未来气候变化的大气环流模式模拟资料，由於模拟全球性气候变化而资料的网格划分尺度较大，对於河川流域此等尺度较小的改变无法反映出区域变化特性。

The main relative systems of heavy-hard rainfall in northeast plateau are Western Pacific Subtropical High, South Asia High, Low Latitude Systems, Upper Level Jet , Low Level Greater Wind Speed Axes, Westerly Trough and Plateau Trough, Low Level Vortex, Cold Frontal, Occluded Front in Qinghai Lake, Mesoscale Low Pressure, Heat Low-Pressure in Qinghai, shear line and convergence line, mesoscale cloud cluster, etc.

西太平洋副高、南亚高压、低纬系统、高空急流、低空大风速轴；西风槽和高原槽、低涡、冷锋、青海湖锢囚锋以及中尺度低压、青海热低压、切变线与辐合线、中尺度云团等系统是高原东北部地区大到暴雨的主要相关系统。100hPa上的南亚高压中心强度加强，位置东西摆动预示高原地区将有降水产生，中心强度减弱，降水过程结束。

Nanomaterials — whose tiny components are less than 0.1 micrometres in size but larger than molecules — are prized because their properties differ from those of their larger-scale counterparts.

纳米材料的成分不足0.1微米大，但是比分子要大一些，它们被推崇是因为其性能与比它们尺度大的同类材料不同。

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。
