Anyway, we proposed a more detailed structure model of this kind of ATPases using staphylococcal CadA as an example.

总而言之，以葡萄球菌上的CadA当一个例子，我们提供了CPx型腺核甘三磷酸酵素这类蛋白更完整的结构模型。

Structural magnetic resonance imaging include lineal mesure, volume measure and volume rendered. They can detect the abnormal brain structure, especially the change of mesial temporal lobe in early onset of Alzheimer s disease. Recent studies more focused on functional imaging which can find the functional changes in brain. Prior to structural changes, functional changes happen, so it can reflect the sutile pathological process in Alzheimer s disease.

磁共振成像结构影像学主要介绍了磁共振成像线性和面积测量、磁共振成像体积测量和磁共振容积再现三方面，其研究热点主要集中于阿尔茨海默病患者异常脑结构的分布，以及特征性结构内侧颞叶，尤其是海马，杏仁核，以及内嗅皮质在结构在阿尔茨海默病早期诊断治疗中的作用。

Methods:50 whole brains were serially horizonatally sliced with each section 2 mm in thickness.The two -dimensional image of each section was corrected and aligned at first.After corre spondence by experts identifying thalami,tiling based on contour matching and surface-fitting with NURBS interpolation,thalami were reconstructed on computer.

These three cladograms describe the evolutionary relation of microRNAgenes. We find the cladograms of 8-mer based on Spearman correlation and distancedefinition are consistent with the actual evolution relation among species.

所得的三种microRNA进化树与物种实际进化关系相当，其中，又以核苷多联体的Spearman相关和物种距离定义所得进化树与实际进化关系最为接近。

Therefore, this research intends to address the design of chuandou timber frame and the construction concepts of the master carpenter Liao Chih-te's school by analyzing the master's actual Lóh-ko record. Analysis of the Tng-ko and evidences from actual examples yield the following results. First, from the Lóh-ko procedure one can comprehend the proportional scale and measurements of the master carpenter. Second, Liao Chih-te's construction cases are scanned in three-dimensions; the measurements thus obtained match that from the Lóh-ko procedure.
