起伏

They swooped over the surface of the planet, over twilight-shrouded jungles, undulating plains of grass, and shadow-filled canyons.

他们猛然下降到行星的表面，越过黄昏遮盖的丛林，波浪起伏的草原，充满阴影的峡谷。

It now varies from open grass plains in the south, savannah with scattered acacia trees in the centre, hilly, wooded grassland in the north, to extensive woodland and black clay plains to the west.

它的南部是开阔的大草原，中部是稀树草原，草原中央零星地点缀着洋槐树，北部是起伏的植被茂密的草地，西部则是广阔的林地和黑土平原。

今天的塞伦盖蒂，南面是广阔的草原，中部是散生着刺槐的热带稀树草原，而北部是丘陵起伏、树木繁茂的草场，西部则是一望无际的森林和黑色粘土平原。

Similarly, transformation of potential fields (gravitational and magnetic field) from a curved surface to a plane can also be understood as a forward numerical modeling problem.

对于重力场和磁力场，其在起伏地表条件下的空间换算问题在实质上也是一种正演问题，可纳入到复杂地表数值模拟的框架内去理解和处理。

Anyway I feel that the harp is the most poetic musical instrument: it has a smooth and undulate shape, best being played by a woman in a white embroidered hellenic gown with a tight sash, showing her concinnity and charming figure, with her hair in a high knot,and wearing no jewelry but asandalwood bracelet. Her mistlike azure blue eyes droop down; her typical Grecian nose and thin curving lips are kissable andher face is as sharp as a statuary with a light smile; her nicety long fingers pluck the strings elegantly, from which music flows out, sparkling and harmonic. Maybe she is the Psyche who stepped out of the Anderson's fairytales, even we can see her translucent wings flapping with the rhythm in the air.

不过还是觉得竖琴算是乐器中最富诗意的一种了：外形流畅起伏动人心弦，由穿着古希腊白色刺绣长袍，紧束腰带，显露出优美动人的体态，盘着高高的发髻却除了宽大的手镯外别无饰物的女人弹奏，湛蓝的眼睛低垂迷茫，鼻子优美高挺，嘴角翘起，噙着淡淡的微笑，脸庞如同雕像一般轮廓分明，十指纤细修长，优雅的不慌不忙的拨动着琴弦，音乐如水一般从闪耀着光芒的琴弦间流出；也许就是安徒生童话里走出来的那位活生生的普赛克，甚至都可以看到她的两只透明的翅膀随着音乐扇动着。

Therefore we use mathematical grey scale morphology to realize the background estimation and elimination.

随地形起伏动态选择阈值，实现自适应阈值法的全局分割。

In the night as flooding tide of sea ,i feel the slightly gurgitation , it's too dark to see the far destination .,i believe you as believe the box and needle of the sea

这个大海般涨潮的夜晚，我可以感觉到它微微的起伏。黑暗中看不到远方的目的地，我信任你，如同信任海上的罗盘。

As one of frame data of National Spatial Data Infrastructure , Digital Elevation Model excels contour line. it can express continuous gurgitation of ground, and it can also carry out relevant mathematical analyses and imitation, so it is applied broadly in various fields at present.

数字高程模型DEM是国家空间数据基础设施的框架数据之一，其弥补了等高线的不足，既能表示地面的连续起伏变化，又适合作相应的数学分析和模拟，现在已在各个领域得到了广泛的应用。

The axial direction and radial direction spectrum is blue-shift or red-shift. On axial direction, the blue-shift or red-shift increases with the relative propagation distance, truncation parameter, refractive index constant increases and temporal coherence length decreases, and the spectral-shift gurgitation becom gragually steady. On radial direction, spectral switches appear, and the truncation parameter, spatial coherence parameter, temporal coherence length and refractive index constant also influence critical position and transition height et al.

光谱沿轴向、径向均出现蓝移或红移，随着相对传输距离、光阑截断参数、空间相干参数及折射率结构常数的增大，脉冲时间相干长度的减小，轴向光谱蓝移量或红移量逐渐增大，并且由明显地起伏逐渐趋于稳定，沿径向出现了光谱开关，光阑截断参数、脉冲时间相干长度、空间相干参数和折射率结构常数对光谱开关的数目、光谱开关的临界位置和光谱跃迁量等也产生影响。

Financial and European stocks may continue to gyrate on the latest developments, but in the end I expect the crisis to be resolved.

虽然金融和欧洲股票走势可能受近期事态发展而起伏不定，但是我认为最终危机将得到解决。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.

实际上 我们已接通卫星可视电话了
