<正>绝大多数游客来到柬埔寨,暹粒是最直接的目的地,在这里可以参观拜访各座巧压天工的寺庙古迹,而烟波浩渺的洞里萨湖往往会被游客错过,其实它壮观的湖景和独特的人文景致也值得你将它列入行程。在高棉文里,洞里萨湖(onle Sa)的意思为"大湖",和其他江河湖泊一样,它同样也有一个美丽的传说:传说在湖底住着一尊NAGA(七头蛇神),有一天蛇神的女儿要嫁给印度王子,但女儿仍没有体面的嫁妆,心急如焚,NAGA灵机一动,张开大嘴把洞里萨湖的湖水给吸干了,转眼间,被吸干的河床变成一大块肥沃的土地,成为女儿丰足的嫁妆。从此,NAGA一直驻守此湖,平时任凭湖水高涨,每年11月至次年4月,他便张开大嘴,用力吸尽湖水。 相似文献

2300多年前,希腊的马其顿国王亚历山大四处征战,东打到波斯,南打到北非,每征服一个地方,就在那里建一座以他的名字命名的城市。至今仍能为世人所知的,是公元前332年他在埃及建立的亚历山大城,在今后的100年中,它成为了埃及的首都。如今亚历山大是埃及和非洲第二大城市,埃及最大的港口,世界第一 相似文献

"守护之船"守护,意味着什么?守护意味着,作为一艘战船,它活着,就是为了保卫它的人民;守护意味着,作为一艘战船,它死去,它的灵魂也在抚慰着它的人民;守护意味着,作为一艘战船,无论它活着还是死去,它的人民都永远怀念着它。是之为守护。 相似文献

沼泽碳酸盐是盐水从淡到浓的沉积物,具有成土作用的证据,是环海或湖的典型沉积物(Freytet,1973; Freytet 和Plaziat,1982; Alonso-Zarza,2003).如果气候允许,它们能形成在位于海岸平原和潮坪的浅水、富碳、由淡到浓的盐水沼泽中 (Monty和Hardie,1976;Shinn,1983; Platt和Wright,1992).在这些边缘海环境中,沼泽沉积能覆盖数千平方千米,可能伴随发生喀斯特和钙质结壳岩现象(Platt和Wright,1992). 相似文献

Offshore waters provide resources for human beings,while on the other hand,threaten them because of marine disasters.Ocean stations are part of offshore observation networks,and the quality of their data is of great significance for exploiting and protecting the ocean.We used hourly mean wave height,temperature,and pressure real-time observation data taken in the Xiaomaidao station(in Qingdao,China)from June 1,2017,to May 31,2018,to explore the data quality using eight quality control methods,and to discriminate the most effective method for Xiaomaidao station.After using the eight quality control methods,the percentages of the mean wave height,temperature,and pressure data that passed the tests were 89.6%,88.3%,and 98.6%,respectively.With the marine disaster(wave alarm report)data,the values failed in the test mainly due to the influence of aging observation equipment and missing data transmissions.The mean wave height is often affected by dynamic marine disasters,so the continuity test method is not effective.The correlation test with other related parameters would be more useful for the mean wave height. 相似文献

2012年1月31日船位:南纬41°22.674′东经174°49.359′今天早晨起床感觉像好了一样,身上很舒服,直接坐在了值班的位置,还为大家做了一顿饭,我觉得受了伤还是要活动一下,这样也会恢复得快些。可大家说,你要躺在床上没事也要装作有事,上岸的时候我们要把你抬上去,我说要是肋骨长上了或者没断怎么办,大家就开玩笑说要烙铁准备一个锤子,不行就再来一下。现在不断都不行了,免得新西兰说我们骗签 相似文献

Marine dynamic disasters,including storm surges,huge waves,and sea ice,are the most harmful natural disasters aff ecting coastal countries in the world.Under the infl uence of global climate change,the mechanisms,frequencies,and damage severity of marine dynamic disasters are exhibiting new characteristics.The enormity,unpredictability,and chain eff ects of these disasters have become increasingly prominent,and the losses endured by coastal countries around the world have been increasing year by year.Therefore,the prediction of,risk assessment for,and emergency response to marine dynamic disasters are important issues for disaster prevention and mitigation worldwide. 相似文献

Oceans and seas form a large body of water that contains a natural biodiversity.For humans,represents a resource,which makes this a point of interest,from researches to improve the economy.Seaweeds produce many compounds and secondary metabolites that can be used in different fi elds of industry such as food,agricultural,pharmaceutical and health.Even though seaweeds are ancestral resources,recently it was notorious a global interest in knowing more about its potentials,where biotechnology plays an important role in research.Studies showed that seaweed has many bioactive compounds benefi cial to plant development,giving them a great potential as an agricultural fertilizer.Adding seaweeds to the soil provides organic matter,minerals,trace elements,growth plant regulator,metabolites,vitamins,and amino acids and it can work as a soil conditioner.In Portugal,the use of seaweeds for agriculture is important since long time ago.In the past,populations that lived near coastal zone depended on the seaweeds as a family subsistence but,throughout the years,synthetic fertilizers replaced seaweeds.Our work aimed to assess the potential of the extracts obtained from Ascophyllum nodosum and from Sargassum muticum as an agricultural fertilizer.This evaluation was carried out with rice plants(Oryza sativa)and lettuce(Lactuca sativa),in germination bioassays,the culture of rice and lettuce plants in pots,and culture of lettuce plants in hydroponics.For that,seaweed liquid extracts were used in different concentrations in different bioassays.Results show that extracts obtained from two seaweeds,A.nodosum and S.muticum,can be promissory plant biofertilizer at a concentration of 25% and had a positive effect on seed germination,plant development,and production. 相似文献

<正>每年的初夏时节,海上升起的平流雾,像丝锦般将海岛环绕,倒影随着海浪涌动,仿若轻歌曼舞,给海中的长岛平添婀娜的一面。从蓬莱港码头乘上渡轮,航行约半个小时,只见前方云浮海上,山耸云间,恍惚间以为是海市蜃楼。此时此景,远来的游客瞩目远眺,刚刚在渡轮上的拥挤与嘈杂顷刻间散尽,而船上返家的岛民却低着头忙不迭的收拾着行李,见怪不怪地念叨着:"到家了,到家了。"是的,我此行的目的地长岛到了。 相似文献

<正>有读者来信,希望小编们推荐适合家养的观赏鱼,那就趁着本月的情人节主题推荐给大家一种很有意思的热带鱼——接吻鱼。接吻鱼又叫亲嘴鱼、吻鱼、吻嘴鱼、香吻鱼、接吻斗鱼等,属鲈形目、吻鲈科、钉嘴鱼属,体色为浅红色,以鱼喜相互"接吻"而闻名。实际上,同性鱼也有"接吻"动作,故一般认为接吻鱼的"接吻"并不是友情表示,也许是一种争斗。接吻鱼游动起来十分缓慢,显得仪态万千,是极具观赏性的热带鱼。因为鱼体微红带白好似初放的桃花,所以还有很多行家叫它桃花鱼。接吻鱼喜欢栖息于热带河流中,在原产地常被作为一种食用鱼。它对水质的要求不严,群居性不太明显,游动起来十分缓慢,显得雍容大方,具有迷人的魅力和观赏价值。 相似文献
