However, in this field of study in China there still exists five points of issues as follows:(1) the forecast of natural gas hydrate resource at the sea is exaggerated;(2) studies on hydrate reservoiring dynamics, reservoiring system, and especially the hydrocarbon source are not enough as well;(3) research on physical stratigraphy of hydrate sedimentary reservoir rocks is still blank;(4) the relationships among the BSR in the seismic profile, blind zone of amplitude, and sedimentary reservoir are still unknown;(5) the exploration technical studies are not complete and systematic yet.

但是，中国海域天然气水合物的勘探研究还存在5个方面的主要问题：海域天然气水合物资源量预测过大；对天然气水合物成藏动力学、成藏体系研究不够，尤其是对烃源研究不够；中国在天然气水合物沉积层岩石物理方面的研究几乎还是空白；对地震剖面上的BSR、振幅空白带与天然气水合物沉积层的关系仍然不是十分清楚；中国目前的天然气水合物勘探技术研究还不够深入、不够系统。

The research shows that the percent recovery of natural gas and condensate oil in core experiments are larger than one in PVT experiments; the real relative permeability curves have a significant effect on the percent recovery;. retrograded condensate oil of lower condensate oil system can not second evaporate reciprocally in low permeability cores.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
