The results show that the kerf width increases with the increase of laser power, pulse frequency, pulse width and assist gas pressure, but decreases with the increase of cutting speed.

结果表明：缝宽随输出功率、频率、脉宽及辅助氧压的增大而增加，随着切割速度的增加而减小。

The results showed that the kerf width increases with the increase of the power density, pulse frequency and pulse width; the cutting speed is increased and the cutting quality is improved with increasing the pulse frequency.

结果表明，缝宽随激光功率密度、频率以及脉宽的增加而加大；提高激光输出重复频率，不仅有利于提高加工质量，而且可以增大切割速度，提高加工效率。

5H2O, triclinic. Crystal and for the rare, mostly for fiber implicit crystal - amorphous aggregates, showing hull shape, tumor-like, tuberculosis-like, kidney-shaped or a vein.

5H2O，三斜晶系。晶体及为少见，多为纤维隐晶——非晶质集合体，呈皮壳状、瘤状、结核状、肾状或脉状。

From 1970's,there are 111 kimberlite veins or pipes to have been found.As much as half of Chinese original diamond reserves are located there.

从20世纪70年代发现金伯利岩以来，该区已发现111个金伯利岩脉，原生金刚石矿储量占全国总储量的一半以上。

The kimberlite has the intensive magnetism, low resistivity, and high content of Cr、Ni and Nb. Its geophysical and geochemical prospecting anomaly over the earth's surface are mostly shaped in ellipse and ribbon, which is paragenetic with fracture structure.

金伯利岩的分布严格受断裂构造控制，矿体呈管状、脉状，具有成群、结带分布的特征；它具有磁性强、电阻率低、微量元素Cr、Ni 、Nb含量高的特征。

But in the industrial era after the Korean War, the stream, by then a rank open sewer, was entombed by pavement and forgotten beneath a lacework of elevated expressways as the city's population swelled toward 10 million.

但韩战后的工业时代，当时已成恶臭难闻无盖大水沟的这条河流，被道路埋进地底，而随著首尔人口膨胀到一千万，这条河流就在一条高架快速公路的网脉底下，遭到遗忘。

Calyx lobes 3-4 mm; leaf blade lateral veins 12-16 pairs; disk cup-shaped, irregularly laciniate.

萼裂片3-4毫米；叶片侧脉12-16 对；花盘杯状，不规则条裂。 41 D。 laciniata 翼柄瑞香

1:250000 geological mapping has further revealed the mysteries of the tectonics of the Qinghai-Tibet Plateau. The Altun Mountains are not of the Tarim massif, but a part of the Kunlun-Qilian-Qinling orogenic system; the Altun fault is a large transform fault; the Muztag-Maqên suture zone and Jinshajiang suture zone are both Variscan ones; the Songpan-Garzê area in the Triassic was a huge turbidite basin on the southern margin of Laurasia; the Gangdise belt underwent the important Indosinian orogenic movement; an ocean basin that persisted from the Paleozoic to Triassic did not exist, i.e. the so-called Paleo-Tethys or permanent Tethys was not in existence in the Qinghai-Tibet Plateau. In the Paleozoic, most parts of China, including the Sino-Korean, Yangtze and Tarim massifs and the Qinghai-Tibet Plateau, were located in south of the main ocean basin—the Central Asian-Mongolian sea way—of the Paleo-Asia ocean, belonging to the northern margin of Gondwana. The Yarlung Zangbo and Bangong -Nujiang belts were twins in the Tethyan Ocean, which began to develop into two ocean rift belts in the Triassic. The Tethyan Ocean with the Yarlung Zangbo belt as the main ocean basin belt began to be subducted in the Late Triassic and experienced a process of pulsatory plate convergence orogeny including the Indosinian, Yanshanian and Himalayan stages.

1：25万地质填图进一步揭开了青藏高原地区大地构造的奥秘：阿尔金山是昆仑，祁连-秦岭造山系的一部分；阿尔金断裂确是一条大型转换断层；木孜塔格-玛沁缝合带和金沙江缝合带均是华力西缝合带；松潘甘孜三叠系沉积盆地是劳亚大陆南部边缘的浊积岩盆地；冈底斯带曾经历了重要的印支造山运动；不存在从古生代延续到三叠纪的大洋盆地，即不存在所谓古特提斯或永久特提斯；古生代时期，在青藏高原地区亦不存在具古生物，古地理分隔意义的大洋盆地，当时，包括中朝，扬子，塔里木以及青藏高原地区在内的中国大部分均位于古亚洲洋主洋盆——中亚-蒙古带之南，属冈瓦纳大陆结构复杂的北部边缘；雅鲁藏布江和班公湖-怒江带是特提斯洋中的孪生姊妹，它们均是从三叠纪起就发展成大洋裂谷带的；以雅鲁藏布江带为主洋盆带的特提斯洋，从三叠纪晚期开始消减，经历了印支，燕山，喜马拉雅3个阶段脉动式板块汇聚造山过程。

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
