空间曲线

Therefore, if the developer according to these requirements in a breakdown of market competition, the ideal state, product sales in general there will not be much suspense, basically revolves around the value of leveraged呈波浪style ups and downs, the author had drawn a "Shouzheng Marketing sine curve ", that is, in order to explain this problem, space is limited, this do not want to go.

因此，如果开发商按照这些要求在崩溃的市场竞争中，理想的状态，产品销售一般不会有太大悬念，基本上是围绕着价值杠杆呈波浪式起伏，作者曾吸引了"守营销正弦曲线"，也就是说，是为了解释这个问题，空间是有限的，这个不想去。

Last, this paper introduced some concepts of multiscale geometrical analysis and curvelet transform theory. Because curvelet can showed this feature more 'sparsely' in the function included singular curve or singular side in two dimension space or multi-dimension space. This paper provided a robust digital watermarking technology algorithm based on curvelet transform. watermarking information was embedded into coarse scale coefficients after curvelet transforming, choose right embedding strength. Testing proved it has good invisibility and robustness.

最后，介绍了多尺度几何分析和曲波变换理论的相关概念，鉴于曲波能对二维乃至高维空间中含奇异曲线或者曲面的函数进行更"稀疏"地表示这一特性，本章提出了一种基于Curvelet变换的鲁棒数字图像水印算法，该算法将水印信息嵌入到经曲波变换后的图像的粗尺度系数中，合理选择的嵌入强度，试验表明该算法具有较好的隐蔽性和鲁棒性。

Methods A new basis, to be called H-Bézier basis, is constructed for the space Γ=span{1, t, t^2,…t(superscript n-2), sinh t , cosh t}(n≥2) by an integral approach.

The content included (1) characterizing macropres shapes;(2) obtaining the index to charaterizing soil macropore quantificationally through digitalizing and analysising the photo of soil section;(3) comparing the shapes of macropores among soils, which reasons were discussed;(4) studying the influence of the zonal diversity, soil depth and land utilization on macropore characeristics;(5) estimating the space variability of macropore in the microscale using spore variability index;(6) analysising the connectivity and sinuosity of macropore using preferential flow breakthrough curve;(7) discussing the feasibility of indicating the preferential flow degree using macroporosity and macropore perimeter.

系统划分了大孔隙类型；描述了大孔隙形态；通过对土壤切片图像数字化处理和分析，获得了描述大孔隙特征的两个基本指标：大孔隙度和周长，并对大孔隙进行了定量化地描述；比较了各土类之间大孔隙的形态差异，从土壤发生学的角度对其原因进行了分析；研究了地带性差异、土壤层次和土地利用方式对大孔隙特征的影响；阐明了小尺度范围大孔隙的空间分布特征；结合Br〓标记优先水流穿透曲线分析了大孔隙的连通性和弯曲性，探讨大孔隙形态指标评价大孔隙优先水流作用强弱的可行性。

It has some advantages, such as easy to trackthe curve, smooth curve and hard to cross.

但是该方法最大的问题是不能有效地找到曲线来拟合已知空间变量。

Through transforming the vibration isolation system differential combined equations to the state space equation,it is possible to facilitate the solution of vibration isolation coefficient curve of vibration isolation system by using the Matlab/Simulink module.

通过将隔振系统的微分方程组转化为状态空间方程，使用Matlab/Simulink模块可方便求解隔振系统的隔振系数曲线。

However, one side effect of this approach is that the trace of an object in the time-distance space is a curve.

不过， 一个副作用的方式，即追踪一个物体在时间空间的距离是一条曲线。

For example, a line is affinely infinite while an oval space curve is affinely finite.

如空间中一条直线是仿射无限的，而一条卵形曲线是仿射有限的。

Experimental results of typical complicated space curve seams indicate that the algorithm considers optimization for both torch orientation and robot kinematics, it is relatively high in efficiency and quality, and is robust.

典型的空间复杂曲线焊缝的实验验证结果表明：算法综合考虑了焊枪姿态和机器人运动学的优化，具有较高的规划效率和规划质量，具有较强的适应能力。

Say a first-choice project, A, needs no hours, so it uses no space under the hours curve.

讲的首选项目，这是一个需要没有时间，所以使用任何空间根据小时曲线。

Do you know, i need you to come back

你知道吗，我需要你回来
