曲线弯曲点

This model has been applied to simulate the crack extension in three point bending creep test.

应用该模型，对三点弯曲蠕变试验中裂缝的扩展过程进行了有限元计算，发现裂缝扩展随时间的变化与应力—应变曲线的形状，尤其是强度破坏点以后的曲线形状密切相关。

In order to model complex hair styles, such as curly hairs and wavy hairs, we first construct five types of surfaces and three curves: curved cylinder, curved circular frustum, curved prism, curved edged frustum, curved revolving paraboloid, and curved cylinder helix, curved circular frustum helix and curved revolving paraboloid helix. Then we give the expressions for points and normal vectors on these surfaces, suitable to composition.

为了构造复杂发型，例如卷发发型和波浪发型，我们首先构造了五种曲面和三种曲线：弯曲圆柱面、弯曲圆台面、弯曲棱柱面、弯曲棱台面和弯曲旋转抛物面，以及弯曲圆柱螺线、弯曲圆台螺线和弯曲旋转抛物螺线，并且给出了这些曲线曲面上适合于拼接的点和向量的表示方式。

The segment of a supply curve in Figure 5.1 is not completely defined; if points to the left of it are attainable, it is a "backward-bending" supply curve; if points above it are, it is a "forward-falling" supply curve.

图5.1中的供给曲线线段没有确切的定义；如果曲线左边的各点是可实现的，那么它是"向后弯曲"的供给曲线；如果曲线上面的各点是可实现的，那么它是"向前下降"的供给曲线。

Elastic modulus of specimen processed by PPT method and HP method are obtained by adopting three-point bend test and tensile test of unnotched specimen respectively.

采用无缺口试件的三点弯曲试验，得出PPT法制备的试件的弹性模量；通过柔度变化率曲线上的第一转折点得出基体的破坏应变，并由此得到基体的强度。

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。
