In this paper, beginning with the characteristic of space structure of graphite, we explain its layer structure and choose lattice in a layer which is called hexangular lattice as our studied object.

本论文从石墨的空间结构特点出发，说明了其层状结构，并且把石墨一层内的晶格即六角格子作为研究对象。

2 Newly built low, multi-story residential houses in the old city must be topped with hipped roofs, the existing flat roofs must be gradually converted into hipped roofs.

15.0.2 对旧城内新建的低层、多层住宅，必须采用坡屋顶形式；已建的平屋顶住宅，必须逐步改为坡顶。

However, the processing technologies of stitched composites are relatively more complicated. Stitching has negetive effect on some inplane mechanical properties, and the advantage of great interface mechanical properties cannot be brought into play under hygrothermal conditions.

但是， 缝合复合材料的工艺相对比较复杂，缝合对层合板的部分面内力学性能存在一定的负面影响，而且在湿热环境条件下其层间强度高的优势无法发挥。

Results The artery frequency spectrum of high speed and low resistance were found in malignant trophoblastic tumors. The ulterine muscular layer in malignant trophoblastic tumor was hypervascular and the resistive index was less than 0.4. After chemotherapy, the hypervascularity decreased, RI increased higher, and β-HCG returned normal.

结果 恶性滋养细胞肿瘤子宫动脉RI值较低，为高速低阻力性动脉频谱；恶性滋养细胞肿瘤宫壁血流异常丰富，子宫肌层病灶内血管阻力指数RI.4；恶性滋养细胞肿瘤患者全身化疗取得疗效后子宫肌层血流丰富区逐渐缩小，RI呈逐渐升高趋势，血β-HCG逐渐恢复正常。

In this paper, a three dimensional finite element analysis method is used to analyze the difference of the mechanics response under different vehicles and different loading with different interbedded touch types in asphalt pavement of simi-rigid base layer and flexible base layer.

然而，为了更好地了解沥青路面结构在均匀分布与非均匀分布轮载作用下的力学行为，仍有必要对层间不同接触条件下路面结构层内的力学响应差异进行研究。

The rat hindlimb representation of S1 area is likely to have at least 2 patterns of neural circuits on brain slices: one is the intracortical circuit formed by interlaminar connections from layers II-III, and the other is the thalamocortical circuit mediated by afferent connections from layer IV.

相反，在II-III层，同样的强直刺激并未能明显诱导LTP的发生。结论大鼠S1区的后肢代表区似乎存在两种不同类型的神经回路，一种是由层间联系介导的皮层内回路，另一种则是由丘脑皮层传入介导的丘脑皮层连接回路。

Results The local intracortical connection, which is involved in mediation of downward information flow across layers II-VI, was identified by electrical stimulation at layers II-III.

结果 刺激S1后肢代表区脑片的II-III层，可鉴定出局部皮层内的连接回路，而刺激IV层则鉴定出丘脑皮层间的连接回路。

At first,the curve of charge distribution,ionizable state of nonisothermatity sphere,Was obtained by computer to calculate ionized state according to distribution data of temperature and dinsity within Earth. Secondly,the pussibility of microgravitational testonosphere,Within the isothermality sphere,was found by balance between pressure and volumetric forcein Earth's interior.The thickness is 1 000 km or so.Finally,the result come into commom use various geophysical process withi...

首先依据地球内部温度和密度不均匀分布数据，用计算机计算它的电离状态，得到非等温分层电离状态的电荷分布曲线；其次从地球内部存在的流体压力与两类体积力：重力和静电力的平衡方程讨论中，发现在某一等温层内可能存在微重力构造圈，其厚度约为1000km左右；最后在地学研究向整体化和深部化发展趋势下，预期这个结果将有助于理解地球深部发生的各种物理过程且与地震S波在核－幔之间层中消失观测事实相一致。

Methods Axial lamellate computed tomography scans of frontal drainage system were firstly performed with four layers spiral CT, and coronal, sagittal sections then reconstructed with AW 4.1 software on 65 adults ,both frontal sinusitis group (35 cases, 66 sides) and control group (30 cases. 59 sides). Related cells in frontal drainage system were studied and compared dynamically.

采用4层螺旋CT对65例成人，30例正常成人及35例额窦炎患者的额窦引流通道行水平位薄层扫描后用Advantage Windows 4.1(AW4.1)影像工作站进行冠状位、矢状位重建，动态分析和比较两组额窦引流通道内出现的相关气房。

Nodal and Activin, members of TGF-βsuperfamily, are mediated by the TGF-βreceptors ALK4 or ALK7, and they play important roles in mesendoderm induction and anteroposterior patterning of the neuroectoderm.

TGFβ家族的信号转导由TGFβ受体ALK4或ALK7介导，在脊椎动物胚胎的中胚层和内胚层诱导以及神经外胚层的前-后轴线分化中起着重要作用。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.
