Therefore, the moist potential vorticity analysis associated with the mesoscale convective system was researched in the paper, so as to reveal the moist potential characteristics of mesoscale convective system in typhoon circulation. The results showed that, during the generation stage, convective instability characterized by MPV1 was a favorable condition for forming MCS, while the vorticity which was caused by the slantwise isentropic surface and the vertical shear of the horizontal wind characterized by MPV2 was an inspiring mechanism. The specific process was that, the atmosphere exhibited the feature of strong convective instability at the low level of convection areas and the southeast areas, which included plenty of erratic energy. The slantwise ascended the stream transfer the erratic energy to northwest, where the stratification stability was small. As decreased, the cyclonic vorticity increased. On the other hand, the vorticity caused by the slantwise isentropic surface and the vertical shear of the horizontal wind inspired the release of convective instability and as a result that the MCS formed. During the development stage, the cyclonic vorticity increased quickly with the persistent decreasing of . Meanwhile, the inclination of isentropic linewas bigger than the absolute momentum line at middle level, which exhibited the feature of conditional symmetric instability , then the conditional symmetric instability was forced to release by the vorticity resulted from the slantwise isentropic surface and the vertical shear of horizontal wind, and the MCS developed.

结果表明，在对流形成阶段，MPV1即对流不稳定为MCS的形成提供背景不稳定条件，由MPV2即湿等熵面的倾斜和水平风的垂直切变而引起的涡旋发展作为强迫机制：MCS形成的区域及东南区域中低层是强对流不稳定层，蕴含丰富的不稳定能量，倾斜上升运动把对流不稳定区具有强不稳定能量的暖湿空气向西北中层的中性层结区输送，由于的减小，气旋性涡度增强，有利于形成对流，另一方面，由于湿等熵面倾斜和低空急流加强而引起的涡旋发展作为一种强迫机制激发对流不稳定能量得到释放，从而形成对流；在对流系统地发展阶段，由于低层的对流不稳定性进一步减弱，进一步减小，气旋性涡度进一步增强，有利于MCS的增强，中层等θe 线的倾斜度比绝对动量M 等值线的倾斜度大，对应有条件对称不稳定区域，满足条件对称不稳定条件，在湿等熵面倾斜和台风低空急流作用下引起的涡旋发展强迫对称不稳定能量释放，从而使得对流得以维持和加强。

长期以来，我国文化遗产工作者一直注重对有形的物质文化遗产进行收集、整理和研究，对无形的非物质文化遗产关注较少，虽有过民俗学、民族学的一些工作，但由于种种原因，相关资料保存至今较少，从非物质文化遗产保护的角度进行探讨更是新近才开始的，这些工作比国际先行国家落后很多，如在保护制度上，我国2005年才开始"民族民间文化传承人"调查和认证，这比日本的"国家文化财"制度落后了50多年，比联合国教科文组织"活的文化财"保护计划也晚了10多年；在制度和法规的建设，日本、韩国、法国等国家早己建立了保护制度，通过了相关法律，而我国在这方面基本还是空白。

I observ'd the poor affectionate Creature every two Minutes, or perhaps less, all the while he was here, turn'd his Head about, to see if his Father was in the same Place, and Posture, as he left him sitting; and at last he found he was not to be seen; at which he started up, and without speaking a Word, flew with that Swiftness to him, that one could scarce perceive his Feet to touch the Ground, as he went: But when he came, he only found he had laid himself down to ease his Limbs; so Friday came back to me presently, and I then spoke to the Spaniard to let Friday help him up if he could, and lead him to the Boat, and then he should carry him to our Dwelling, where I would take Care of him: But Friday, a lusty strong Fellow, took the Spaniard quite up upon his Back, and carry'd him away to the Boat, and set him down softly upon the Side or Gunnel of the Canoe, with his Feet in the inside of it, and then lifted him quite in, and set him close to his Father, and presently stepping out again, launched the Boat off, and paddled it along the Shore faster than I could walk, tho' the Wind blew pretty hard too; so he brought them both safe into our Creek; and leaving them in the Boat, runs away to fetch the other Canoe.

不料星期五力大无比，一下子把那西班牙人背在身上，向小船那边走去。到了船边，星期五把西班牙人朝里轻轻放到船沿上，又把他拖起来往里一挪，安置在他父亲身旁。然后，星期五立即跳出小船，把船推到水里，划着它沿岸驶去。尽管这时风已刮得很大了，可他划得比我走还快。他把他俩安全地载到那条小河里，让他们在船里等着，他自己又马上翻身回来，去取海边的另一只独木舟。我在半路遇上他，问他上哪儿去。他说："去取那只小船。"说完又一阵风似地跑了，比谁都跑得快，甚至可以说比马都跑得快。
