The results indicate that the electron loss timescales due to artificial injection of ELF/VLF waves in the inner and the outer radiation belts depend largely on the value of the cold-plasma parameter α*(∝ B 2/ N 0, where B is the ambient magnetic field and N 0 the electron number density), the properties of wave frequency spectrum, the wave power and the electron energy in resonance with the waves.

数值计算结果表明，在内、外辐射带由于ELF/VLF波的人工注入而造成的高能电子损失时间尺度很大程度上取决于冷等离子体参量α*(∝ B 2/ N 0，这里 B 是背景磁场， N 0是电子数密度)、电波频谱特性和功率，以及与波发生回旋共振的电子能量。

However, the spatial variability of diversity of annual and biennial herbaceous plants, shrubs, intermediate xerophytes and xerophytes is low.

沙质草场群落中一、二年生草本、灌木、中旱生植物和旱生植物功能群多样性空间变异性较弱，由随机因素引起的异质性所占的比重较大，且主要表现在5 m以下的尺度范围内。

Wing is more large than the average worktables, you can enlarge the working surface of yourtable or bench, by placing a particle board over it.

房的尺度比平均的工作台大，藉由放置在它上的一个颗粒薄板你能扩大你的表或平台的工作表面。

There is still great uncertainty about the nature of ecological thresholds and how they are related in different spatial scales.

由于生态因子相互作用的复杂性，有关生态阈值的性质及其在不同空间尺度上的联系仍然存在很大的不确定性。

May be impossible. Pan of the reason why these swaps can be done is the willingness of

大自然交换的代价的另一个问题是在一个大的尺度上使用或许是不可能的。

The prognosis of concealed ore body is characterized by the large scale,small region and high-precision.

隐伏矿体预测，具有大比例、小尺度和高精度的特点。

In this paper,The effection of hybrid fibers including steel fiber,Dura fiber and Dolanit fiber as two elements or three elements on the mechanical properties and impermeability of high-performance cementitious matrix with the composite of high percentage pulverised steel slag and expansive agent are investigated systematically.

研究了钢纤维、Dura纤维和Dolanit纤维按二元或三元混杂对大掺量磨细钢渣与膨胀剂复合的高性能水泥基复合材料的力学性能和抗渗性能的影响，从不同尺度与不同性质的纤维在相应结构层次上的叠加效应角度来阐述水泥基复合材料的防渗抗裂机理。

Investigate the assisting of the relation and soil and groundwater monitoring data among the surface feature and image established the relation of the spectrum characteristic with surface feature ,using two kinds of classification and improved post-classification, methods lies two respects: 1Salt steep spectrum luminance value curve of ground higher than surface feature average luminance value curve obviously, and other surface feature luminance value lower than or have around average luminance value curve little wave water body mean the land water areas among them obviously, including the river and surface of water , surface of water of the reservoir and hole pool surface of water By view trend of the

从计算结果得出，盐渍地上的NDVI 值分布在一定范围内，这样就可以取一定的阀值，将反射率较低的盐渍地提取出来。根据盐渍地分布与地下水的相互关系，对分类后的图像进行处理，提高了精度。2 充分利用遥感与GIS 技术在地学分析中的优势，计算各类盐渍地面积、荒漠、水体面积变化，分析近三十年来研究区土地盐渍化动态变化的规律，包括面积变化、盐渍化程度的变化，分析大范围时间尺度上土地盐渍化动态发展的整体趋势。

The criteria of appearance defects,dimensional precision,weight range and process parameters are set up.

传统的CAE分析以经验确定分析结果的评价尺度，或由用户提供质量要求，由于用户对质量的要求大多是描述性的，甚至还有许多用户对CAE分析结果评价的质量要求不明确，与定量要求差异很大。

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。
