坑

In addition to the heavily cratered terrain, Mercury also has regions of relatively smooth plains.

除了大量坑地形，水星也有地区的相对平稳平原。

Much of the Martian surface is very old and cratered, but there are also much younger rift valleys, ridges, hills and plains.

大部分的火星表面是非常古老和坑，但也有更年轻的裂痕峡谷，山脊，丘陵和平原。

There are two primary types of terrain on the Moon: the heavily cratered and very old highlands and the relatively smooth and younger maria.

有两个主要类型的地形在月球上：重坑和非常古老的高原和相对平滑与年轻的玛丽亚。

The southern hemisphere of Mars is predominantly ancient cratered highlands somewhat similar to the Moon.

南半球的主要是古代火星坑高地有些类似月球。

The surface cratered with the constant dropping of water.

表面因长年不断地滴水而成坑凹。

The results showed that dentinal tubule orifices were better closed under 56~111 J/cm2 energy output and no crater or fissure was found.

结果证实56~111 J/cm2的能量，就能较好地封闭牙本质小管口，并且不会产生大的凹坑及裂纹。

The laser irradiation of 0.4/300s can better blocked dentinal tubule orifice, and will not cause crack and pit.

激光功率0.4W，照射时间300s条件下，牙本质小管封闭厚度较厚，且不出现凹坑现象，可作为半导体激光脱敏的最佳参考数值。

Doline visual depth at the position seems to tens of meters, the rope length should be enough!...

天坑在这个位置上目测深度好象就几十米，绳索长度应该是够了！。。。

In fact, there are many down the road, lonely sea is absolutely no reason for depression do not know what position to reach the doline ...

其实这里有很多下去的路，孤海之所以忧郁不绝就是不知道想到达天坑的什么位置。。。。

Yibin is 26 "doline" added: 112 villagers transfer...

宜宾现26个&天坑&续：112户村民转移。。。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
