And very possibly there are abundant oil and gas resources in Kashi depression.

同时喀什凹陷还可能赋存有丰富的油气资源，深化其新生代构造特征及发展演化的研究对基础地球科学探索和油气资源的勘探开发都具有重要的意义。

Plicate carpel 6~8, initiated in a whorl stimultaneously. Euryale" s floral organogenesis is similar to Nymphaea" s except the apex of Euryale s floral primordium caved in at early stage.

芡实的花器官发生方式与睡莲的基本一致，两者的区别仅在于，芡实花原基的先端在早期就已向下凹陷。

Therefore we carried out seismic sedimentological studies in Qikou Sag of Huanghua Depression using two techniques,that is,phase shift and stratal slicing .

目前国际上掀起了地震沉积学的研究热潮，国外学者在北美、印度等含油气盆地进行了一系列的地震沉积学研究，并在油气勘探和开发方面取得了明显的效果，因此本文利用相位调整和地层切片两项关键技术，对黄骅坳陷歧南凹陷沙一层序进行了地震沉积学的研究。

And that is, women when they are insecure, struggling with something or they feel threatened, they'll touch their neck dimple (that's that little area right below the Adam's apple it's also called the suprasternal notch) So they could be on the phone talking about the creep they just saw and they'll put their hand over this area.

那就是，妇女，当他们不安全，挣扎着的东西，或他们觉得受到威胁，他们就会触及其颈部凹陷（即的小面积的权利，低于亚当的苹果它也被称为suprasternal缺口），使他们可以谈在手机上关于蠕变，他们只看到他们也会把他们交给这方面的工作。

During the preresearch on the testing well location selection in the south of western depression, three kinds of process and research work have been done according to the log datum on Well Moushen:(1)Formation analysis and formation pressure evaluation which verdicts that formation under 5198.5m is not of Trias, whereas is still in Permian, and abnormal formation pressure phenomenon exists in Members 1 and 3-4 of Shahejie Formation;(2)Re-interpretation of oil and gas formation and evaluation of reserve formation;(3)Evaluation of oil source rock. Members 1 and 3-4 source rocks of Shahejie Formation have good capability of oil generation.

在东濮凹陷西洼南部探井选位的前期研究中，根据该井的测井资料情况，做了三方面处理和研究工作：①地层分析和地层压力评价，认为5198.5m以下的地层不是三叠系而仍是下第三系，沙一段和沙三段—沙四段存在高压异常；②重新解释油气层和评价储集层，在沙三段—沙四段发现6层12.87m厚可疑油层；③评价油源岩，认为沙一段和沙三段—沙四段油源岩具有较好的生油能力。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
