查询词典 parameter curve

The different width and length of Hilbert curve geometries were investigated by finite element method. The computation results show that the DGS rejects the signal at two frequencies 2.43 GHz and 7.11 GHz from 0~9 GHz with more than -15 dB suppression. Q factors of the Hilbert curve DGS is bigger than that of conventional DGS.

通过有限元法对不同Hilbert曲线宽度和长度的DGS结构微带线进行计算，计算结果表明，该结构在0~9 GHz频段内表现出2.43 GHz和7.11 GHz这2个谐振频率，对应频率的通带反射损耗低于-15 dB，并且阻带特性在谐振频率处比传统DGS微带线有更高的 Q 值。

With the increase of amylum quantity, the color of each the standard solution iodine combined with amylum changes dark and the its absorbance enlarges, the linear part in standard curve enlarges, while the amylum quantity are 20 ml and 50 ml respectively, the length of linear part in standard curve is not changed, so the optimum quantity of amylum is 20 ml.

对于碘标准系列溶液，随着显色剂淀粉用量的增加，溶液的颜色加深，吸光度在增大，标准曲线的线性部分加长，加入淀粉为20 ml和50 ml时，直线部分的长度变化不大，因此，加入20 ml最为理想。

In order to control the flow separation by reducing the diffusion factor and enlarging the diameter of inner circle, the meridian plane profile of the return channel was redesigned, which is achieved by substituting arbitrary curve for the circle with no change of the axial length of the stage. Bezier curve with eight parameters was chose to describe the shape of meridian plane profile, and the optimization of the meridian plane profile was implemented combining back-propagation neural network with genetic algorithm.

改进的主要思路是减小弯道前半部分通道的扩压度，并同时加大弯道出口内侧的转弯半径，主要做法是在不增加整级轴向尺寸的前提下，用任意曲线取代传统弯道的同心圆环结构，给定弯道回流器子午型线的外侧型线，采用Bezier曲线对内侧型线的2段曲线进行参数化描述，利用遗传算法和反向传播(back-propagation，BP)神经网络相结合的方法对内侧型线进行优化，得到新的弯道回流器子午型线。

Two new methods were developed for selecting a PB-S curve with some confidence percentile level as the planning curve.

提出了两种新方法用于选择一定置信度要求的PB-S曲线作为项目的基准计划曲线。

However, at some point factors such as lack of nutrients, accumulated wastes, etc., limit further increase, when the curve of number against time begins to level off and the curve becomes sigmoid.

然而一些关键性因素如营养物的缺乏、代谢产物的积累等，限制了进一步的增长。

In the chapter 3, the development and characteristic of TM image and DEM is explained generally. In following chapter, how to measure backwater curve using remote sensing and DEM is particular expounded, including revise the backwater curve using water level data which is measured by hydrology station.

在第三章中概括性的叙述了TM遥感影像与DEM的发展过程及特点，在随后的章节中详细的阐述了遥感影像结合DEM测定水库回水曲线以及利用水位站点实测数据进行校正等内容。

I am just a common person, why I not only saw the identity of time and space, but also saw the multi-dimension. I saw the "curve light", and I saw the "not curve light" and "light of black hole" too, how amazing! How beautiful!

我是极普通的人呀，为什么我不仅看到了时间和空间的"同一性"还看到了它们的"多维性"；"弯曲的光"我看到了，"不弯曲的光"和"黑洞的光"竟然也被我看到了，太不可思义！

The line of curvature isn't only a curve of space, but a special and a very important curve of surface.

曲率线不仅是一条空间曲线，而且是曲面上定义的一种特殊而重要的曲线。

The chord is closed by drawing a line from the intersection of the first radial and the curve to the intersection of the second radial and the curve.

在第一个径向线和曲线的交点与第二个径向线和曲线的交点之间画一条直线得到的就是一个弦。

There are three curve types: linear, secondary curve and interpolation method.

曲线类型具有：线性、二次曲线、插值法。
