| 1. | The earth is believed to have a liquid core .
人们相信地球有一个液态核。 |
| 2. | Liquid core of optic fiber ( lcof ) is a new - style optic fiber , it is adopted transparent liquid as its core
液芯光纤( lcof )是一种新型结构的光纤，采用透明液体作为光纤的芯料。 |
| 3. | Plumes are thought to be columns of exceptionally hot material rising from deep within the earth ' s mantle , perhaps even from its bottom , where the mantle contacts the earth ' s liquid core
地慢羽被认为是米自地慢深处异常炽热的柱体，或许来自连接地球液体核的地慢的底部。 |
| 4. | Because we cannot get down into the liquid core to observe what actually is happening , we have to make inferences based on measurements made on or above the earth ' s surface
因为我们不能下到流体地核内部去观察那里实际上发生了什么，所以我们不得不依靠在地表上或地表以上的测量来推断。 |
| 5. | ( 2 ) research on the solidification of liquid core to seek after the rule of the changing light intensity . ( 3 ) study on the damage and repair of the lcof
( 3 )液芯光纤损伤与修复的实验研究：对损伤的液芯光纤进行承载实验研究；将损伤后的液芯光纤进行光固化修复，对修复全程进行监控，对修复后的液芯光纤进行了承载实验研究。 |
| 6. | That the earth has an iron - rich liquid core , sufficient energy to drive convection and a coriolis force to twist the convecting fluid are primary reasons why the geodynamo has sustained itself for billions of years
地球拥有富含铁的液态核心、有足够的能量驱动对流，并具有科氏力可使对流的流体扭转，这些是地球发电机之所以能自我维持数十亿年的主要原因。 |
| 7. | When the lcof is damaged , it can be repaired by its liquid core which is radiated by special illumination , and the repaired lcof can be still used to inspect the structure of composite materials . so the lcof has great application value
当液芯光纤受到损伤时，利用芯液对损伤处进行修复，修复后的液芯光纤依然保持着良好的承载传感性能，可以继续对复合材料结构进行监控。 |
| 8. | Different liquid systems can be used in different wavebands . so the choice of liquid core is greatly abroad . in recently , there are many researches reported , but these researches mostly focus on its optic spectrum and easy application
近年来，液芯光纤的研究也有不少报道，但这些研究大多停留在对其光谱特性以及一些简单的应用研究，其应用层次比较低，应用面比较窄，并没有得到广泛的推广。 |
