The raw data was processed by using axial, coronal and double oblique multi-planar reformation; Images obtained were graded in terms of quality with a 5-point scale(5=excellent, 4=good, 3=fair, 2=poor, and 1=nondiagnostic). In grading image quality at axial MPR, The radiologic specialists focused on the subarcuate fossa, tendon of tensor tympani, facial recess, vestibular aqueduct and pyramidal eminence, In grading image quality at coronal MPR, attention was given to the scute, crista transversa, fenestra cochleae, lateral malleal ligament and snake eyes signature of cranial nerve, In the grading of the image quality at double oblique MPR, the radiologic specialists concentrated on the malleus, incus, stirrup bone, upper bony semicircular and aquaeductus fallopii, and then to implement statistical analysis. In order to choose the minimum tube current values and the maximum pitch that can satisfy the diagnosis request, image quality of axial, coronal and double oblique reformation images was compared with different tube current groups. 15 ears of volunteers were used to test the validity with the scanning parameter. Subsequently noise, MTF and dose length product were measured by phantoms in different tube current and pitch, the parameters obtained were compared and taken into statistics analysis.

The unit bottom was the unconformity developed by Wuling Movement, and the unit top was overlapped by glacial deposition of Nanhua System. What\'s more, an unconformity can be found in Northern Guizhou and North-western Hunan. At the same time, this boundary was an important transformation between different deposition types: Banxi Group was rift basin deposition with flysch suite, and bearing a vast amount of pyroclasts, and this suggests that there was strong activity of crust. But the overlapping glacial deposition stood for steady deposition with penecaprock characteristic, and under unique climate environment.

下为武陵运动形成的角度不整合面所限；其上被南华冰期沉积所超覆，在黔北—湘西北可见角度不大的不整合，而且这一界面是两个不同沉积类型或建造之间的一个转换：板溪群为具有复理石韵律的裂谷系充填，其中发育大量火山碎屑沉积，显示较强的地壳活动性；而上覆的南华冰期沉积所代表的是一个具有准盖层性质的、独特气候环境下的稳定沉积。

This dissertation draw a conclusion that the deposition of rift basin in early Neoproterozoic in eastern Guizhou consisted of three lithostratigraphic units in Xiang-Qian-Gui rift basin, not only developed typical Banxi Group, but also deposited grayish green Xiajiang Group with flysch suite in eastern Guizhou, and Danzhou group like in Northern Guangxi, by studying depositional sequences, sedimentary systems, depositional lithofacies and paleo-geography, sequence stratigraphy, event stratigraphy (analyzing the stages of volcanic events) and the stratigraphic correlation between Xiajiang group and the other Group in adjacent region and so on, on the basis of predecessors\' data and achievement in scientific research.
