Based on available effort and information,the authors summarize the temporal-spatial relation between the distribution of CO_2 and hot fluid flow, analyse the positive and negative effect of the hot fluid flow on CO_2 accumulation, and build up the model of CO_2 accumulation dominated by hot fluid diapir.

在前人的研究基础上，详细地总结了CO2分布与热流体活动在平面、纵向和时间上的对应特征，认为热流体活动与CO2分布的确存在一定的对应关系；同时，认为热流体可以促进CO2气源形成，可作为CO2气运移的载体，同时促进运移通道的扩大，也为CO2气运移提供能量，流体在上侵过程中与围岩发生反应，改造了CO2气储层，热流体在向上释放能量的过程中，造成上覆地层的拱起，形成圈闭，最终也可控制CO2气成藏。

The bigger top tension will cause the wellhead to be over-pulled and increase the probability of wellhead collapse. As the mean drifting of drilling vessel or platform increases, the wellhead displacement and bending moment nearly linear enlarges. The greater current velocity may result in wellhead instability because of its limited bearing moment capacity. Therefore the drifting control is very important to subsea wellhead stability. The wellhead stability may be improved by taking measures such as enhancing the conductor bending strength, controlling scour depth on seabed, getting geological data sampling of shallow formations.

算例分析表明，水下井口的横向偏移及弯矩随张力比和海流流速的增加而大幅增大，顶张力过大会引起井口稳定性变差；随着钻井船或平台漂移量的增加，井口的横向偏移和弯矩近似线性增加，控制好钻井船或平台的漂移非常重要；由于井口承受弯矩的能力有限，较大海流流速情况下可能造成井口失稳；提高导管抗弯强度、控制泥线处管柱冲刷、获取浅部地层的取样数据等措施可以增强井口稳定性。

It is found that there is a co-relationship between the boron isotope and chemical composition of magmatic tourmaline: the δ〓B value increases with increasing Al and Li in Y-site of tourmalines. The low δ〓B values (-41. 1～-39. 01‰) in Altay No. 3 pegmatite, which is one of the lowest values found by now, imply that non-marine evaporites might exist in magma source, or the pegmatitic magma had been assimilated by them during its intrusion and emplacement.

阿尔泰3号伟晶岩最初形成的结构带中电气石的B同位素组成是目前所发现的最低值之一(-41.11～-39.01‰)，指示形成伟晶岩脉的初始岩浆可能由含非海相蒸发岩的泥质岩经变质深熔作用形成，或是伟晶岩岩浆在上侵定位过程中同化了含非海相蒸发岩地层的结果。

Given what geologists think the temperature of these zircons was when they formed, that means the diamonds were probably squeezed into being by the pressure of 100-150 kilometres of crustal rock lying above them.

交给地址学家思考的问题是，这些锆石形成时的温度，这意味着钻石很可能被100到150公里厚的地层的压力下被挤压形成的。
