The lingguotong shopping center , liberation square , the people s theater , xinhua bookstore , with the national beauty spot of 4a grade - famous districts such as the sea floor world , seaside park , bund seafood island , etc 邻国通购物中心解放广场人民剧场新华书店，与国家4a级景点-海底世界海滨公园外沙海鲜岛等著名区近在咫尺。
The results show that before the summer monsoon onset , the air - sea heat exchange near xisha area is weak , the vapor flux is small and the main trend is that the ocean is being heated ; while after its onset , the air - sea heat exchange is balanced roughly 结果表明：季风爆发前，西沙海气界面热量交换较弱，水汽通量较小，以海洋获得热量为主；季风爆发后，海气界面热量交换接近平衡。
According to these anomalous implications , some possible areas for gas hydrates are pointed out , such as the xisha trough , the dongsha island slope , the marginal bijianan basin , the north luzon trench , the nansha troug , the middle - south to southwest okinawa trough etc 中国近海海域的西沙海槽、东沙群岛岛坡、笔架南盆地、北吕宋海槽、南沙海槽、冲绳海槽中南部至西南部等是天然气水合物的可能赋存区。
According to the topography and geomorphology , the abnormality of gravitation and magnetic field , characteristics of crust structure and the environment of lithospheric dynamics in the northwestern of the south china sea , the seismic profiles were explained across the yinggehai basin and xisha trough 摘要本文根据南海西北部壳体的地形地貌、重磁场异常和地壳结构特征和岩石圈动力学环境，对穿过莺歌海盆地和西沙海槽的地震剖面进行解释。
