不变的

The designing way of this paper about the forebody and afterbody of aerocraft is based on the wave-rider theory, so design the aerocraft upper and down surface separately, besides keeping the length and thickness of forebody and afterbody constant, to some extent ensure the whole aerocraft design target and avoid the conflict with other disciplines, The flow solver takes use of Euler equations, combining with the technique of the unstructured dynamic meshes.

文中对飞行器前后体设计思路基于高超音速乘波体的思想，将飞行器上下表面进行分离设计，在前后体的长度厚度以及发动机的位置保持不变的条件下，较大程度避免了飞行器整体外形布局的改变，从而一定程度上保证了总体设计的目标，大大缓和了与飞行器其他学科设计时的冲突。

According to the calculated proportion of aniline and dye, if the other reaction condition is maintained, and the proportion in electrolyte is changed, the DS-PAn film with different sensation properties can be obtained, i. e. absorption range and intensity in visible spectrum can be controlled by the proportion of aniline and dye.

实验证实，可以通过预先计算苯胺与染料的比例，在电解液中改变苯胺与染料的比例，保持其他电化学反应条件不变的情况下，在经过一定时间反应后，可在多种衬底上生成不同增感效果的DS-PAn薄膜，同时此薄膜在可见光区的吸收谱带的宽度和强度可由聚苯胺与染料的比例来控制。

It all adds up to a headache for Fan Jinshi,director of the Dunhuang Academy,who is under constant pressure to grant more tourist access even as she oversees the protection of the caves on a barebones budget funded by ticket receipts and the state.

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）。

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。
