连续曲线

This is an all in a row, but not all derivatives of the curve.

这是一种处处连续，但又处处无导数的曲线。

Which is called the arc differential of the curve.

设函数在区间内具有连续导数，且曲线上点的弧长为，则弧长的微分是。

The CCT curves of two kinds of steels were tested with heat dilatometer at different cooling rate. Corresponding microstructures were observed with LASER microscope.

The surface generated by a straight line, the generator, passing through a fixed point, the vertex, and moving along a fixed curve, the directrix.

锥面由一条直线，即母线，通过一固定点，即顶点，沿一给定曲线，即准线，连续移动而产生的平面

Since these merits, Dyn's four-point scheme is one of the classical subdivision schemes in CAGD.

本文讨论的是前者。1987年，Dyn提出了四点细分算法，它形式简单，最高具有四次收敛阶，并可以生成一阶连续的极限曲线，由于这些明显的优点，四点法成为CAGD中经典的细分算法。

In addition, through plotting the hydrograph of mean annual and natural yearly runoff and the residual mass diagram of frequency factor from 1919 to 2002 in Sanmenxia Station, 2 continuous low water periods from 1922 to 1932 and from 1990 to 2002 are obtained.

通过绘制多年均值和天然年径流量过程线以及模比系数差积曲线，得出黄河三门峡站1919～2002年系列中存在1922～1932年和1990～2002年两个连续枯水段。

To establish GPS buoy above the surface near Tide Gauge for continuously monitoring sea level change and dealing with the dynamic relative positioning of the GPS tracking station integrated with the Tide Gauge, the instantaneous position of GPS buoy can be solved. Then based on ellipsoid height of each point and time series, the curve of height distribution is drawn. The curve can represent the instantaneous position of the sea surface.

在潮位站附近海水面上设置GPS浮标，持续量测海水面之变化，并与潮位站共构之GPS连续追踪站，进行动态相对定位，可解算出GPS浮标瞬间位置，再撷取其椭球高，以时间序列绘制此高程分布图，此曲线就代表海水面随时间变化之瞬间位置。

The impenetrability of the star cores is known to cause a discontinuity in the osmotic pressure showed through a peak in the scattering functions.

另外，还研究了不同拉伸状态下，不同官能度f的星型高分子链的散射因子，星型高分子"核心"的不可穿透性导致了渗透压的不连续，反应到散射函数曲线上有一个峰值。

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。
