The two of them growing old and frail together in the rambling weatherboard house on Zamia Street in Townsville---the way their eyes would meet and the way they would not speak openly of such a difficult and unseemly thing as this, but would each know the other's mind and would bear it in silence.

For one-dimension optimization problem, stage pressure ratio and flow angles at the stator trailing edges, solidities at the stator and rotor trailing edges are considered as design parameters, To demonstrate feasibility of the present method, a multiobjective optimization of a six-stage compressor design was performed for maximization of the overall isentropic efficiency and the total pressure ratio, It obtained dozens of reasonable and uniformly distributed Pareto-optimal solutions that outperformed the baseline design in both objectives.

对于一维优化问题，以某六级高压压气机为对象，选取各级的级压比和静子出口气流角以及转子、静子的稠度为变量，得到了几十个在两个目标上均优于初始设计的Pareto最优解。

And then the influence of two of the damage models, the Kachanov and the gradient-dependent constitutive equations, on the well-posed properties of the fundamental equations in continuum damage mechanics is studied according to the characteristic method of the quasi-linear partial differential equations under the case of one dimension elastic damage.

首先从非局部理论出发，推导了应变梯度损伤本构方程；然后利用一阶拟线性偏微分方程组的特征理论，在一维弹性损伤情况下分析了两种不同的本构模型，即Kachanov损伤本构方程与应变梯度损伤本构方程，对连续介质损伤力学基本方程适定性的影响。

We illustrate our methods using data from self-intersecting curves, surfaces in 2D/3D and higher-dimensional spaces.

我们还给出了两维和三维欧氏空间中自相交曲线和曲面的例子，以及更高维空间中的实际例子，以说明该算法的有效性。

因为 这只两岁大的小家伙本杰明，喜欢骑上他主人的哈利戴维森生产的摩托车到处转。

One is pose estimation strategy that can be used to obtain the vertical rotation angle of the facial image, and the other is 3D deformable template matching which can be employed to extract the eye features of the facial image.

此方法采用了两个新提出的技术，一个是人脸姿态估计策略用于估测人脸的垂直旋转方向，另一个就是三维可变形模板匹配技术用于具体提取眼睛的精确特征。
