The generally southward paths for oil to migrate out of Taibei depression can be two ways. One of them is from Taibei depression to Yubei structural zone and the other is from Taibei depression to Lukeqin structural zone. By the both ways, oil migrated upward along the faults and southeastward along the structural axis to concentrate in either Permian or Triassic system.

油气运移路径的总趋势，一是由台北凹陷由北往南运移直抵玉北构造带，再沿断层向上进入二叠系和三叠系运载层，二是由台北凹陷运移至鲁克沁构造带西端进入三叠系运载层，进入两构造带的油气沿构造轴部由西北向东南上倾方向运移。

In general, fan delta is well developed at the steep slope of faulted basin. Through the correlation of fan delta to standard deltaic parasequence model, a well-developed fan-delta succession could fall into two parasequences.

扇三角洲相在断陷湖盆的陡坡一侧发育，通过与标准三角洲副层序模式对比，一个完整的扇三角洲序列可以划分出两个副层序。

Feb. 1988, quasi-biennial and quasi-3-to-4-year oscillation are invenstigated. It is found that the two oscillations are propagating from west to east at all levels, being out of paase for the tropics but in phase for the mid-latitudes; for the latter oscillations in West Pacific, it travels equatorially from both mid-latitudes at low-levels while from south to north through a well-defined channel at...

结果发现：纬向风准两年、准3─4年振荡在热带地区上、下层均一致自西向东传播，但位相相反；在中纬度地区，纬向风准两年、准3─4年振荡上、下层均盛行自西向东传播，且位相一致；西太平洋地区低层纬向风准3─4年振荡均为从南、北半球中纬度地区向赤道传播；高层纬向风准3─4年振荡在175─140°W附近存在一明显的通道，且为自南向北传播，而且在经向上呈1波特征。

Methods Axial lamellate computed tomography scans of frontal drainage system were firstly performed with four layers spiral CT, and coronal, sagittal sections then reconstructed with AW 4.1 software on 65 adults ,both frontal sinusitis group (35 cases, 66 sides) and control group (30 cases. 59 sides). Related cells in frontal drainage system were studied and compared dynamically.

采用4层螺旋CT对65例成人，30例正常成人及35例额窦炎患者的额窦引流通道行水平位薄层扫描后用Advantage Windows 4.1(AW4.1)影像工作站进行冠状位、矢状位重建，动态分析和比较两组额窦引流通道内出现的相关气房。
