地下洞穴

A well-preserved late 2nd century mithraeum, with its altar and built-in stone benches, originally built beneath a Roman house, survives in the crypt over which has been built the Basilica of San Clemente, Rome.

一个保存良好的二世纪后期的太阳式洞穴，连同着祭坛和固定的石造长椅子，最初是建造在一座罗马房子底下，幸存地在罗马圣克莱门长方形会堂的地下室内。

Hamsters are primarily considered crepuscular because they live underground during most of the day, only leaving their burrows about an hour before sundown and then returning when it gets dark.

仓鼠主要是考虑黄昏，因为他们大多数生活在地下的一天，只留下他们的洞穴前约一小时，然后返回太阳落山时，被蒙在鼓里。

Now the perils of the Dungeons are many, and some time later, when Iolo entered Despise (more carefully than Edric had, for Iolo knew the place of old), he was soon greeted by a black and gaping deadfall.

地下城里的危险很多，不久以后，当Iolo进入"轻视"时（比Edric更为小心，因为Iolo早就知道这地方了），他很快就遇到了黑色且多洞穴的"死伏"（陷阱的一种，一堆交错倒下的树木）。

The spotted hyena spends its day in holes in the ground, or in rocky dens.

鬣狗花了一天洞在地下，或在岩石洞穴。

The cave might never have been discovered had not the entrance been spotted by the distinguished French pot-holer, Berger.

英尺。这个深邃的洞穴是由一条地下暗泉冲刷岩石中的缝隙并使之慢慢变大而形成的。

Before the swallow, before the daffodil, and not much later than the snowdrop, the common toad salutes the coming of spring after his own fashion, which is to emerge from a hole in the ground, where he has lain buried since the previous autumn, and crawl as rapidly as possible towards the nearest suitable patch of water.

春燕还没归来，水仙花还没绽开，经过一冬的蛰伏，蟾蜍爬出深埋地下的洞穴，向行将来到的春光致意，他沐浴着雪花莲的芬芳，迫不及待地奔向最近处的水洼。

Myspalax cansus (Rodentia, Myospalacinae, Myspalax)which lives on the loess plateau of our country. This unique underground rats life-long living under the cave, it developed many hypoxic tolerance protect mechanism to adapt its special circumstances at in organsall levels. In this study,we used Gansu zokor and SD rats (Sprague-Dawley)for the object, do serious hypoxia tolerance experiment, to explore the hypoxia tolerance extreme of Gansu zokor, analysis the difference hypoxia tolerance between Gansu zokor and SD rats at same oxygen concentration; The changes on their cardiac muscle organization structures in hypoxia tolerance process ; The expression of HSP70 between normoxic and hypoxic control in cardiac muscle organization of two animals , to find the relativity in all the results.

甘肃鼢鼠隶属啮齿目，鼢鼠亚科，鼢鼠属，是我国黄土高原特有地下鼠，由于终生营地下洞穴生活，使得甘肃鼢鼠发展出良好的低氧耐受保护机制，本研究以甘肃鼢鼠和SD大白鼠(Sprague-Dawley)为对象，进行低氧耐受实验，探寻甘肃鼢鼠的低氧耐受极限，比较二者低氧耐受的差异；以及低氧耐受不同时程，二者心肌组织显微和超微结构的变化差异；比较分析左心室组织中HSP70的表达变化和心肌耐受过程中组织结构变化的相关性。

It extends to a depth of 3,723 feet. The chasm has been formed by an underground stream which has tunneled a course through a flaw in the rocks.

它有3，723尺深，这个深邃的洞穴是一条地下河流冲刷岩石中的裂缝并使之慢慢变大而形成的。

This immense chasm has been formed by an underground stream which has tunneled a course through a flaw in the rocks.

这个深邃的洞穴是由一条地下暗泉冲刷岩石中的缝隙并使之慢慢变大而形成的。

From the water pressure test and the collapsing examples, the thesis analysis the force expression of Karst collapse in water table dropping down, and presents that the additional stress from water table descending in overlying soil layer and rock, which is equal to approximately the descending depth of water table, which can be applied to about ten meters descending depth.

针对地下水位波动引发的岩溶塌陷进行了专门性研究。通过试验文章指出了岩溶区地下水位受迫下降至基岩面以下时的力学效应为：附加力在一定范围内，与在基岩面以上一样，等于水位下降的幅度值，并与盖层下基岩中洞穴的形态及体积无关。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
