Changes in Xc for different pulp cellulose fibers are not the same during the ultrasonic treatment. Crystallization and decrystallization may both exist during the treatment at the conditions of lower-intensity ultrasonic wave. After treatment with ultrasonic Xc of MBKP cellulose is decreased and that of EBKP is increased. The changes of Xc of different pulp cellulose are more closely correlated to the fibers' morphology size and the cavitation state. The maximum Xc of 84% is obtained when BEKP cellulose is treated under the conditions of ultrasonic frequency f=23-25kHz, power=400w, and treatment time t=720s.

不同原料来源的纤维素纤维，由于形态尺寸和超分子结构的差异，经超声波处理后超分子结构表现出不同的变化规律；超声波处理过程中，结晶和消晶两种作用同时存在；超声波功率对纤维素的结晶度有较大的影响，对晶体尺寸有一定程度的影响，但结晶度Xc与超声功率没有线性关系；在频率为23-25kHz，功率为400W条件下，对桉木漂白浆纤维进行超声波处理，可获得高结晶度（84%）的纤维素样品。

As the latest abrupt climate event with temperature decrease from the transition of the last glacial period to the Holocene, the Younger Dryas event that occurred approximately between 12.9 to 11.6 ka BP at north Atlantic is very important on the study of abrupt climate change, while there are still many debates on its trigger site, trigger time, trigger mechanism, as well as whether it is a global event.

大约发生在12.9～11.6 ka BP的新仙女木事件在气候突变的研究中占有重要地位，然而对其触发时间、触发地点、触发机制以及YD事件是否是一个全球性的事件一直存在很大争议，并且该事件触发机制的研究对目前全球温度快速升高背景下未来气候变化的预测也有很大的意义。

Sweet is the breath of morn, her rising sweet, With charm of earliest Birds; pleasant the Sun When first on this delightful Land he spreads His orient Beams, on herb, tree, fruit, and flour, Glistring with dew; fragrant the fertil earth [ 645 ] After soft showers; and sweet the coming on Of grateful Eevning milde, then silent Night With this her solemn Bird and this fair Moon, And these the Gemms of Heav'n, her starrie train: But neither breath of Morn when she ascends [ 650 ] With charm of earliest Birds, nor rising Sun On this delightful land, nor herb, fruit, floure, Glistring with dew, nor fragrance after showers, Nor grateful Eevning mild, nor silent Night With this her solemn Bird, nor walk by Moon, [ 655 ] Or glittering Starr-light without thee is sweet.

同你谈话，我总是忘掉了时间，以及季节的转换，任何时刻都感到高兴：早晨呼吸清鲜空气，和早鸟一同歌唱，觉得舒畅；初升的太阳，在愉快的大地上，抛撒他那蔷薇色的光线，照耀着草、木、花、果，带露晶莹；细雨阵阵过后，丰腴的土地流芳；夕暮来临时心旷神怡，接踵而至的是沉静的夜，她有严肃的鸟儿、美丽的月亮和繁星，天上的宝石。但没有你时，一切都觉变了样：晨风不鲜，早鸟的歌唱不欢，尽管有太阳照耀大地，有草木花果的露珠晶莹，有雨后的流芳，愉悦的夕暮来临，沉静的夜也带来她那严肃的鸟儿，在月亮或亮晶晶的星光下散步，这一切，若没有你便没有快乐。
