不变

The calibration method can generate the sufficient calibration points with high accuracy for structured light system,which decrease error from image processing and cumulative computing according to invariance cross ratio.

该方法可以降低图像处理过程所引入的误差，减少多次交比不变计算标定点所带来的累积误差，得到多组高精度的标定点，从而提高结构光系统的标定精度。

This system uses a cubic phase element and digital image processing to increase the depth of focus in keeping the same illumination and resolution.

设计了一个光学/数字成像系统，该成像系统利用三次位相元件辅以数字图像处理技术，在保持系统光通量及分辨率不变的前提下，提高了光学系统焦深。

Then, using the derivatives of the two dimensional normal cumulative distribution function with respect to its variables of parameters, the sensitivity measure of the failure probability of the parallel system or the unconditional up-crossing rate of the combined process can be determined.

最后利用经典的时不变可靠性分析方法确定并联系统的失效概率，并利用二维正态分布函数的导数特性确定失效概率的敏度。

In the States, on the other hand, we demand triple-shot double-grande caramel macchiatos. And where the French caf -goer takes his coffee in cup and saucer because he values sitting as much as sipping, the American gets his grande on the go, the enormous paper cup a product of his perpetual motion.

并且，当法国的爱咖者将闲坐的价值视同如啜饮的价值同等重要时，他们往往喜欢拿着杯子和碟子驻足停留、享受惬意；但是我们美国人却不停地走在我们所谓的建设国家的道路上，也正是因为我们这种一尘不变的动机使得成千上万的纸杯被大肆生产（却也由此产生了大量浪费）。

The right femur specimens were fixed with DHS augmented by bone cement, as the augmentation group The screw track of femoral neck was expended by curette, and the femoral head facing upwards were injected with 2 mL low viscosity bone cement. Then lag screw was wrested to keep the position unchanged till the bone cement coagulated.

右侧标本行骨水泥强化DHS固定（在股骨头近端钉道用刮匙扩大，股骨头朝下，注入2 mL低黏稠度骨水泥，拧入拉力螺钉，保持位置不变直至骨水泥凝固。

Computational results indicated that magnetic field intensity increases with current and decrease of frequency.

模拟计算表明，结晶器磁场强度随着搅拌电流的增加而增大，电流不变时，频率越小，磁场强度越大。

Geometrical Vectors introduces a more sophisticated approach, which not only brings together many loose ends of the traditional treatment, but also leads directly into the practical use of vectors in general curvilinear coordinates by carefully separating those relationships which are topologically invariant from those which are not.

几何向量引入了更为先进的方法，它不仅汇集了许多传统的治疗无所适从，而且还导致进入载体的实际用途，一般直接通过仔细分离曲线的拓扑关系是从那些没有不变的坐标。

Based on the hypothesis that constant returns to scale,this paper uses cyclic estimate method of frontier cost function to indirectly...

因此，通过提升技术效率，在要素投入水平不变的前提下，能大幅改善产出水平，这将是辽宁省完成节能降耗指标的主要途径。

Compared with the light equation for cylindrical lens, the equation for conelens is much more complicated.

柱透镜在近轴平行光入射时，光线的振幅、相位、周期保持不变，而锥透镜的三者均发生变化，而且求解锥透镜的光线方程也比圆柱透镜复杂得多。

And darkened heart, you love me now!

还是黯淡的心，你已爱我不变！

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
