| 1. | 000 life on earth regresses during a new glacial period 000年前,地球上的生命在一个新的冰河时期中倒退。 |
| 2. | Two thirds of the continent was covered in ice during glacial periods 该大陆的三分之二地区在冰河时代被冰覆盖著。 |
| 3. | Relating to or occurring during the time following a glacial period 冰期后的与冰期后的时期有关的,或在冰期后的时期里发生的 |
| 4. | Above the rock in the right direction , one can see traces of the mountain movement of the glacial period half way at green phoenix peak 站在磕头石的上方往右可以看到绿凤峰半月腰处冰川时期山脉运动的痕迹。 |
| 5. | The first of these glacial periods is often called the huronian glaciation because it is well exposed in rocks just north of lake huron in southern canada 第一次冰期称为休伦冰期,因其遗迹在加拿大南部休伦湖北方的岩石中清晰可见。 |
| 6. | In addition the average sedimentation rate was obviously higher in the interglacial period than in the glacial period in the drilling core ey02 - 1 in the north of mid - shelf 而东海中陆架北部ey02 - 1孔间冰期时的平均沉积速率明显高于冰期时的平均沉积速率。 |
| 7. | It is concluded from our study results that the coastal dunes outside the qilihai lagoon are inherited dune complex formed from the eolian dunes in the last glacial period 研究认为,七里海外的海岸沙丘群是在末次冰期时期风成沙丘群的基础上演化形成的继承性沙丘综合体。 |
| 8. | Considered of the genetic diversity of the 4 possible wild populations combined with the ecological environment of their habitats , populations wc and tm are regarded as the survival habitats in glacial period 在所有研究群体中,栽培的tx群体的遗传多样性水平最低。结合各群体所在地的生态环境综合考虑,认为wc和tm两群体所在地最有可能为野生银杏冰川期避难所。 |
| 9. | Descending the celestial capital peak westwards , travelers go through the immortal gate keeper cave with vivid peach - resembling rock formations on the cave , pass crucian carp peak formed during the glacial period and cross the heavenly bridge where the sea exploring pine stands 在天都峰的西侧往下走,人们要依次经过“仙人把洞门” ,鲫鱼背和天桥, “仙人把洞门”上有形状如桃花的岩石,天桥鲫鱼松形成于冰川时期,天桥上生长有探海松。 |
| 10. | Studies of the petrology , textures and structures , depositional environment , contained fossils and age of the fluvial - lacustrine deposits indicate that they are the earliest record of the epiglacial area of the quaternary glacial period , representing the lower boundary of the quaternary glacial period 对该河湖相沉积的岩石、结构构造、沉积环境、所含化石特徵和形成时代等的研究表明,它是第四纪冰期冰缘区的最早沉积记录,也是第四纪冰期的下限。 |
