Therelevant progress in the loop quantum gravity and superstring are also brieflyreviewed.

还介绍了圈量子引力和超弦理论的相关进展。

We can get the r matrix by the Lax connexion and make quantized procedure of type IIB superstring on AdS5 S5 background.

利用R矩阵，可以对Ad凡x驴背景中的超弦进行量子化。

Based on the example of turbine reverse engineering , the general procedure that can be used to translate the physical object into CAD datum by Surfacer software is determined in this paper1 By going deep into the vector of point-cloud , it's parametrization can be gained by adopting the precept of accumulating chordal parametrization1 According to the principle of const ructing curve using the least square method , the high quality-curve can be gained by modifying curve's parameter1 This paper also empha2sizes on some methods about processing point-cloud , const ructing curve and const ructing surface1 And it can provide several methods to const ruct high quality2CAD model for mould machining1

Theoretical results show that lunate-tail, with high-aspect-ratio, spanwise tapering tip and moderate sweepback angle, of many fast-swimming ocean animals, may gain the nearly best propulsive characteristics.

理论分析表明，高速海洋动物所具有的大展弦比、尖叶梢、中等后掠的新月形尾能获得接近于最佳的推进性能。

The greening that occurs in springtime should be represented by greens on your plate, including Swiss chard, spinach, Romaine lettuce, fresh parsley, and basil.

绿化的，是发生在春天应该派出滚你的板块，其中包括瑞士弦，菠菜，生菜，新鲜香菜，罗勒。

Of course, anyone knows that it is impossible to play a symphonic work with just three strings.

当然，谁都知道，只用三根弦演奏一部交响乐作品是不可能的事。

During the preparatory periods of the Haicheng earthquake and Tangshah earthquake, the occurrences of the stronger earthquakes in the precursory field were related to the moon's phase, the M_L≥4.5 earthquakes of the near-focus field in the trend precursory periods and the M_L≥4.0 earthquakes of the whole precursory field in the periods of the fast-changing precursors tended to occur around syzygy or quarter.

海城和唐山地震的孕震期间，前兆异常区域内的较强地震趋于发生在朔望和上下弦，海城和唐山地震的主序列以及前兆异常区域内1900年以来发生的六级以上强震与月相也存在类似的相关。这些关系可以在地震预报中作参考。

And its tablature illustrates the unique mode, melody formula and charm of Chaozhou Music.

摘 要：潮州音乐的二四谱是因潮州弦诗乐而应运而生的具有独特功能的古乐谱。

Software Description: About Desktop Guitarist, This guitar software lets you create and share chord charts, tablature and MIDI files.

Desktop Guitarist 这个六弦琴软件让你创建和分享弦绘制，乐器指令数字化接口文件。

"A tablature is a system of notation that describes how a note is to be produced, where the finger s are to be placed, rather than defining an absolute pitch."

弦线乐谱这种乐谱标明每一个音符的演奏法，指法，而不确定任何绝对音高。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
