In the shallow soil with the depth of 0~50 cm below the ground surface,the extent from 0 to 50 centimeters, the change of the δ13C of the soil carbonate is positively related with the depth in the upper soil profile from 0~30 cm,but it will increase rapidly in the lower soil profile as the result of the existence of salined and alkali soil layer.

盐碱化土地在0～50 cm的深度范围内，土壤碳酸盐的δ13C值变化规律为：0～30 cm深度内，土壤碳酸盐的δ13C值随深度的增加而逐渐减小；在30～50 cm范围内，如果有盐积层或碱积层的存在，则土壤碳酸盐的δ13C值迅速增加。

Based on integral transformation, analytical solution for the wave transmission equations in 1-D inhomogeneous media is derived. By dividing the media into layers and considering the continuous conditions between the interfaces, the transfer matrix of amplitude of waves is obtained.

利用积分变换，用解析方法求解了一维非均匀区域的不同性质对弹性波传播时波幅变化的影响；将非均匀区域离散成均匀的薄层，结合相邻层的连续条件，建立了数值解法的波幅传递矩阵。

After the water-based clean, the low K dielectric layer is formed on the surface of the barrier layer to achieve the composite layer that has a low K.

在以水为基础者清理之后，低的 K 电介体层在障碍层的表面上被形成达成有低的 K 的含有种种要素的层。

Here have formed in about 14 million years ago to 3 million years between the Mesoproterozoic Jixian System Yunmeng Mountain Group - Upper Carboniferous Taiyuan Formation, exposed systems and complete; has Archaean - Early Mesoproterozoic basement, but also has the typical structure of relics, such as the basement Archaean gneissic complex structure, Early Mesoproterozoic supracrustal rocks at the end of secluded fornix structure, super-nappe cover, ductile shear zone tectonics, ductile - brittle deformation structure of brittle fault cleft construction, single-sided Hill Construction, as well as the cap structure of the collapse, landslides and other structure.

这里有形成于距今约14亿年～3亿年间的中元古界蓟县系云梦山组—上石炭统太原组地层，出露系统而完整；有太古界—早元古界基底，还有典型的构造遗迹，诸如基底太古界片麻杂岩构造，早元古界表壳岩的底僻穹窿构造，盖层的超覆构造，韧性剪切带构造，韧-脆性变形构造，脆性断裂构造，单面山构造，以及盖层中的垮塌构造，滑坡构造等。

In this case,the source of the earth's magnetic field is the current produced by displacement of a double electrical layer's plates appearing on the boundary of the solid and liquid phases of the nucleus (the layer F of Bullen's earth's model).

在这种场合下，地球磁场的本源就是电流，这种电流是由在地核固相与液相边界上的一对带电层的相对运动产生出来的(Bullen地球模型中的F层)。

The geographical compositions of herbaceous plants of shrub-grass plot's soil seed bank indicate that genera of cosmopolitan have a heavy percentage, and indicate furthermore that the growth of herbaceous layer is affected significantly by human being's activities, and many calcifuge plants and indifferent plants in herbaceous layer reflect in certain extent that floristic element and ecological types are intricate.

各样地灌草坡种子库草本植物的地理成分表明世界分布属占较大比重，表明草本层的发育受人为活动的影响较为明显；且草本层中的厌钙植物和随遇植物也较多，从一个侧面反映了在人为活动的干扰影响下区系成分和生态类型的混杂。

We find the exact Green's functions of the Anderson s-d mixing model formagnetic multilayers with arbitrary spin canting angle and arbitrary s-d mixingstrength between two FM layers within the framework of the mean-field theory of theon-site Coulomb repulsion.

在对格点库仑排斥互作用作平均场近似的理论框架内，我们给出了层间系统中Anderson s-d混合模型的严格格林函数。这一格林函数适用于任意的s-d混合作用强度以及两铁磁层的磁化方向间的任意夹角。

The results of the test show that the whole intensity and comprehensive stability of subgrade made a good progress because the capillary water cant rise by using the insulating layer. In the prior condition of taking insulating layer thickness as 0.2m, choosing insulating layer 0.5m, 0.8m, below the pavement, the stability of seasonal frozen soil subgrade is analyzed. The results of the test also show that the optimal position of the insulating layer is 1.0m～1.5m .

试验表明，由于隔离层的作用使得毛细水无法迁移，对路基整体的强度和综合稳定性都有了很大程度上的提高，同时试验还表明在隔离层厚度为0.2m的前提下，设置在距路面以下1.0m～1.5m位置，即路基表面以下0.5m～0.8m处对路基的稳定性最为有利。

MITO, JAPAN — The diktat from the governor was the kind of sweeping order that gives Japanese bureaucrats heart attacks: plans for a three-story airport terminal, painstakingly laid over years, were to be scrapped and replaced with a single-floor layout.

首长的讲话就是一种命令，可以说对日本的行政官员来说都是一次打击：就是花了数年时间辛苦打造的三层航站楼，现在要推到重来，取而代之的将是一层的航站楼。

According to communication system frame of passing SIAS, this article designs a three-layer configuration to communication system, discusser every layer's function.

参考目前变电站综合自动化的通信系统构成，从总体上把该通信系统构成设计为三层，讨论了每一层的功能；详细介绍了通信系统的核心――通信管理机的设计，重点说明了IEC870-5-103规约在其中的应用过程，讨论了在应用中对所实际问题的处理办法。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
