This model not only provides a new method to calculate~(31)P chemical shifts of phosphines,but also establishes the rela...

所建模型不仅在一定程度上阐明了膦类化合物31P NMR谱化学位移与其分子结构信息之间的关系，同时也提供了一种从理论上计算膦类化合物31P NMR谱化学位移的新方法，并对深入了解膦类化合物结构与性能的关系及解析、预测其31P NMR谱提供了一定的理论依据。

Systematic investigations were made on relationship between 31P nuclear magnetic resonance of chemical shifts of 291 phosphines and their molecular structure parameters of phosphorus atoms, such as ionicity index and stereoscopic effect parameters.

One of the most magnificent shifts as of the past month is that new master oversouls have extended into the physical planes upon earth from the Great Central Sun.

上个月（译注：指2004年10月）发生的最壮观变迁之一就是，新的大师级超灵已从大中枢太阳中延展到地球物质层上。

And the surface temperatures simulated in northwestern China are low in the whole year. RegCM2 simulates the characteristic of geographical distribution and seasonal shifts of rain belt in China. But the simulated rainfall is low.

针对上述问题，我们对目前在中国应用较广泛的区域气候模式RegCM2进行了连续5年的模式气候积分，然后根据模式结果全面检验了模式性能，并重点对云—辐射参数化过程中存在问题进行了敏感性试验和改进工作，最后在改进的模式基础上研究了气溶胶的气候效应问题。

The introduction of sequential color steps help to further define the concept by demonstrating movement: time passage through seasons, temperature shifts, or just a rainbow-colored transition that demonstrates order and harmony, not chaos.

采用顺序彩色步骤有助于进一步界定这一概念，表现出运动：时间通过季节，温度变化，或只是一个彩虹色的过渡，表明秩序与和谐，而不是混乱。

In the experiment focused on decadal changes, GCMs reproduce the observed NAO shifts in recent decades by imposing strengthening trends on stratospheric wind. The cooling belt extending from North Africa to subtropical Eurasia is simulated accompanying the strengthening of NAO. East end of this cooling belt reaches the eastern flank of Tibetan Plateau.

在强调年代际变化的实验中，通过在平流层中强迫出水平风场的线性增强趋势，大气环流模式可以模拟出近几十年间冬季NAO指数的年代际上升；伴随着NAO正位相的增强，模式可以再现北非至副热带欧亚大陆的冷却带，且其东端可以到达青藏高原下游地区。

The annual migrations of wild fowl and many other animals certainly cannot be regarded as a form of exploration, because such movements are actually only shifts from one habitat to another for the purpose of avoiding seasonal climatic variations.

野生禽类和许多其他动物每年的迁徙，当然不能被看作是一种探险行为，因为，这些迁徙活动实际上只是从一个栖息地转移到另一个栖息地，以躲避气候的季节性变化。

It remains unscathed while other rocks and minerals melt and re-form under the tremendous heat and pressure of continental shifts, mountain-building, and violent asteroid impacts.

它仍然劫数而其他岩石和矿物融化，重新组成巨大的热力和压力下，大陆转移，山区建设、暴力小行星冲击。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。
