Active fluid flow in the northern South China Sea makes both thermal gas and/or biogenic gas migrate into shallow strata and form hydrate in the gas hydrate stability zone. The fluid flow includes mud diapir and gas chimney structure.

南海北部深水盆地广泛存在的异常热流体活动促使深部的热解成因天然气或浅层的生物成因气运移到水合物稳定带，有利于水合物的发育。

The high geotemperature and superpressure system is mainly located in the diapir belt of the Yinggehai depression in the middle of the basin,so the intrusion of heat flow in the diapir belt , especially the movement of heat fluids of the late Pliocene and the distribution of abnormal high geotemperature and superpressure contro.

莺歌海盆地属南海北部被动大陆边缘新生代异常高温高压盆地，其异常高温高压地层系统主要展布于盆地中部莺歌海坳陷区泥底辟构造带，因此，泥底辟热流体上侵活动，尤其是上新世后期的热流体活动与异常高压区带的展布，控制了天然气及CO2的运聚富集特征。

Mud diapir structures in Yingehai Basin, South Chia Sea provided better channels for gas migration, so that gas at 3000-6000m depth were migrated to 000m shallow reservoirs throught mud diapir structure s and traped in favourable structures.

莺歌海盆地泥底辟构造为天然气运移提供了良好通道，3000~6000m深处的天然气通过泥底辟构造运移到浅部，并在有利构造部位成藏。

There are many calculating methods for dynamic gas reserves. Among them, pressure build-up method and pressure differential curve method are commonly used. This is due to their advantages and actual proof by field tests in application degree. But all of them have their own constraining conditions, so it is difficult to say which one is more reliable.

天然气动态储量的计算方法很多，其中压力恢复法和压差曲线法是计算气井动态储量的常用方法，它们有很多优点，其应用程度已被矿场实际证实，但它们都有各自限制的应用条件，很难说明哪种方法计算更可靠。

Russia denounces America's "diktat and imperialism", talks of a new arms race, threatens oil and gas supplies to neighbours regarded as unfriendly, and says it wants to overturn the Western-inspired economic order.

俄罗斯指责美国的"专制主义和帝国主义"，谈论有关新的军备竞赛，威胁其视为不友好的邻居的石油天然气供应，还有表示它想推翻西方主导的经济秩序。

The property of dimethyl ether is compared with that of LPG and natural gas,and the feasibility of using DME as city gas is discussed.

进行了二甲醚与LPG和天然气的性质比较，探讨了二甲醚作为城市燃气的可行性。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
