1·The groundwater observation well is the basic facility to grasp the groundwater regime, and to appraise and study the groundwater resources.

地下水观测井网是掌握地下水动态，评价与研究地下水资源的基础设施。

2·The groundwater observation well-network for earthquake prediction in China is the largest precursory observation system except the seismograph array.

中国地震地下水动态观测网是我国仅次于测震网的第二大地震前兆观测系统。

3·By combining the theoretical analysis and test, the monitoring method of observation well, by which the volume shrinkage deformation of the cavity can be derived, is provided and verified.

结合理论分析和试验的方法，验证利用观察井监测腔体蠕变收缩体积这种方法的合理性。

4·Well, the first observation is that the velocity vector what can I say about the velocity vector of this motion?

首先，第一个观察到的就是速度向量,关于这个运动中的速度向量，我可以说点什么呢？

5·Well, to answer that we have an easy observation, which is that the vector from Q0 to Q of t is proportional to the vector from Q0 to Q1.

为了回答这个问题，我们观察可以知道，由Q0指向Q的那个向量,和由Q0指向Q1的向量成比例。

6·We need humility in the face of complex problems that require observation, trials, testing — — and honesty to acknowledge when well-intentioned, deeply-committed efforts still don't work.

面对需要观察、尝试、考验的复杂问题，我们需要谦卑；如果为了良好目的付出的艰苦努力没起作用，我们需要诚实地承认。

7·While he was still under observation I didn't think it well to upset him by poisoning his mind with Yvette's slanders.

在他仍处于医生的观察下时，我认为用伊韦特的诽谤毒化他的脑筋、使他不愉快是不妥的。

8·Inductive grounds as well. Here this is observation isn't it and do we have a valid argument here?

也是归纳的基础，这里是观察，不是吗？，我们有一个有效地论点？

9·But there's a limit! Well, I'm not bitching, but simply making an observation.

但这可是有个限度的！我不是在找碴，而只是在观察。

10·The existence of black holes in the universe is well supported by astronomical observation, particularly from studying supernovae and X-ray emissions from active galactic nuclei.

天文学观察很好地支持了宇宙中黑洞存在，特别从研究来自活跃的银河核心超新星和X光辐射。
