Curve functions of axial buccal crown and gingiva contour of each section were acquired by means of curve fitting, and the angle of emergence pofile was calculated, which represents the degree of undercut. Results There is unique relationship between axial crown and gingiva contour individually. This character of tooth is similar to its contralateral tooth.

结果 不同个体的牙冠轴面外形和牙龈外形有其特定的几何关系，同一断面的牙冠轴面外形曲线对应特定的牙龈外形曲线；同名牙同一断面的牙冠轴面外形之间及牙龈外形之间的重叠性很好。

There are some small scale folds in the foliated rock. Their fold axial planes are parallel to the foliation and on the surface of folded foliation, the stretching lineation is parallel to the fold hinges.

在这些片理化岩石中有一些小型褶皱，这些小型褶皱的轴面平行片理面，在被褶皱了的片理面上有着平行褶皱枢纽分布的拉伸线理。

A sheath fold looks like a scabbard or human's tongue. Its fold axial plane or flatten ed plane is parallel to the foliation and there is strong stretching lineation on the sheath fold.

鞘褶皱看起来像一把鞘或是像人的舌头，它的褶皱轴面或压扁面是平行岩石中的片理面的，鞘褶皱上有强烈的拉伸线理。

If every hinge point of a fold in profile are connected, we can get an imaginary plane which divides the fold symmetrically. This imaginary plane is known as axial plane. The geometrical characteristics are used to classify folds.

如果在横断面上将一个褶曲各弯曲层上的枢纽点连接起来，便可得到一个对称分隔褶曲的标志面，这个标志面叫做褶皱轴面，可以用褶皱轴面的几何学特征来作褶皱分类。

Please note this syncline is of inclined axial plane which has the same dip direction as the limb with gentle dip angle.

请注意，这个向斜构造的轴面是倾斜的，轴面的倾向与具有较缓一翼岩层的倾向一致。

For example, the limbs of anticline you have just measured dip toward opposite direction and the dip angles are basically identical. In profile, the anticline has a vertical axial plane. This type of fold is called upright fold.

例如，你们刚才测量的那一个背斜，它的两翼向相反方向倾斜，倾角基本相等，在横剖面上，这个背斜的轴面是垂直的，这种轴面直立的褶皱叫做直立褶皱。

For example, the limb s of anticline you have just measured dip toward opposite direction and the dip angles are basically identical. In profile, the anticline has a vertical axial plane. This type of fold is called upright fold.

例如，你们刚才测量的那一个背斜，它的两翼向相反方向倾斜，倾角基本相等，在横剖面上，这个背斜的轴面是垂直的，这种轴面直立的褶皱叫做直立褶皱。

The optimization of meridional shape is one of the key components that influence the performance of this kind of pumps, and the efficiency on design point can be increased as well as that positive slope of a head-flow performance curve will be improved by modifying the meridional shape reasonably.

轴面图设计是影响斜流泵性能的一个重要因素，通过合理的改进轴面图形状，可以提高设计点效率、改善小流量点的驼峰。

In contrast, P. obliquum has lamina with basal pinnae contracted, scales of petiole brown adaxially, scales of rachis up to 2.3×0.5 mm, pinnae green, chartaceous, matt adaxially, and serrulate on margin, and microscales 0.2-0.5×0.1-0.2 mm.

obliquum相似，但吞天井耳蕨的叶片基部最宽，向基部不缩短，叶柄鳞片近轴面深棕色，叶轴鳞片达3.6×0.8mm，羽片深绿色，近革质，向轴面有光泽，边缘具略波状微齿或近全缘，小鳞片达2×0.5mm；而斜羽耳蕨的叶片的基部缩短，叶柄鳞片向轴面棕色，叶轴鳞片达2.3×0.5mm，羽片绿色，草质，向轴面无光泽，边缘有锯齿，小鳞片达0.5-0.8×0.2-0.3mm。

It means to combine effectively the gradient development model and the point-axis-surface development mode; and in the drainage area economy development coexist the growth pole development, the gradient one and the point-axis-surface one; after the combination of the point development, formed under the polarization effect of and diffusion effect of the growth pole, the band development, formed after the point-axis-surface development, and the generally rational division of labor of the upper, middle, and lower reaches of drainage area economy and gradient development, a huge band growth chain comes into being.

其基本思想是把梯度开发模式与点—轴—面开发模式有机地结合起来，流域经济开发中，增长极开发、梯度开发与点轴面开发模式并存，通过增长极的极化效应和扩散效应所形成的点状开发、点轴面所形成的带状开发与整个流域经济上中下游总体上的合理分工、梯度开发有机结合起来，进而形成带状的巨大增长链。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
