On the Polar ice-cap, 640 kilometers north of the Arctic Circle, the deadly icy winds can freeze a man to death in minutes. But the survivors of the crashed airliner are lucky. They are rescued by three scientists from a nearby weather station. But why did the airliner crash in the first place?

中文摘要：北极，一个永夜的地区，想要生存就必需得更坚强，在一场飞机失事的意外中，一些幸运的生还者，奇迹似的活了下来，并遇上了三位刚好在附近的科学家，但是，飞机为什麼会失事呢？

In addition, the rainfall was consistent with Q vector convergences in the aspects of extent and intensity variation.

In this study,we took a measurement of sound pressure distribution, sound field variability, and effects of frequency shift on sound pressure levels at reference points of pure tone in the diffuse sound field.

本文通过对纯音声压分布、声场变异以及频率漂移对参考点声压级影响的研究发现，扩散场中纯音声压分布的均匀性虽不如啭音，但在某些范围其能量仍可充分扩散，这些区域声场测试结果受受试者头位改变和／或频率漂移影响轻微。对20名重度感音神经性耳聋患者的测试结果证实了上述结论。

The results show that the number of the squeezed atomic dipoles is decided by the coherence of the atom, the direction of the quantum information entropy squeezing is decided by the phases of the field and the atom, and the quantum information entropy squeezing is a precision tool for the squeezing of the atom, especially when the atom is in the eigenstates of the dipole operators.

结果表明：原子偶极矩分量出现信息熵压缩的数目依赖于原子的分布角；信息熵压缩的方向由原子和场的位相决定；量子信息熵是原子压缩的精密量度工具，尤其适合于原子处在偶极矩算符的本征态时压缩情况的描述。

This text aims at the difference of several representative geology conditions in Yang Shui mining area, carried on the primary election to the mining method of Yang Shui mining area, introduced the new theories of numerical optimization choice of mining method that are fuzzy mathematics and artificial neural network etc, based on the existing mining methods that are feasible, adopt the fuzzy optimization choice principle of flexible neural networks, and synthesize several experts and fieldworkers' opinion, built up the related mathematical model and revised model, carried on processing of programming through computer, thus established each optimization mining project under several representative geology conditions in Yang Shui mining area, and carried on optimizing to the existent unreasonable parameter in mining project;have the great significance to aim at each kind of geology condition for each mining area to adjust the mining method in time in the course of mining, abandon chronically unreasonable mining method, full reclaim the mine's resource, lower the dilution rate、 loss rate of mineral mining, raise the production capacity of stope and economic benefit of mine.

本文针对洋水矿区几种典型地质条件差异，对洋水矿区采矿方法进行了初选，介绍了模糊数学和人工神经网络等采矿方法数值优选新理论，在现有可行性采矿方法的基础上，采用弹性神经网络模糊优选原理，并综合多位专家及现场工作者的意见，建立了相关的数学模型及修正模型，通过计算机进行编程处理，从而确立了洋水矿区几种典型地质条件下各自的最优采矿方案，并针对采矿方案中存在的不合理参数进行了优化，为各矿区针对各类地质条件在采矿过程中及时调整采矿方法，摈弃习惯性的不合理采矿方法，充分回收矿山资源、降低矿石开采的贫化率、损失率，提高采场生产能力以及矿山经济效益具有重大意义。

In accordance with the purest tradition of cabarets, each of the four tableaux of the show will end with a spectacle of jugglers, acrobats or illusionists.
