But the geological and geochemical analyses showed that there existed a set of high quality marine source rock in the platform slope facies of Middle Ordovician Pingliang Formation. The oil and gas generated from the source rock of Pingliang Formation was accumulated firstly in the central Palaeo-uplift and its surrounding regions. The thermogenic asphalt in palaeo-uplift carbonate reservoir indicated that oil accumulation completed transition from oil to gas in the Lower Crataceous. Along with the palaeo-uplift axis convection and the formation of westward monocline in the Late Crataceous, gas from the palaeo-reservoir was finally accumulated in the weathering crust of Majiagou carbonate reservoir.

地质和地球化学分析证实，盆地西、南缘台缘深水斜坡相的中奥陶统平凉组存在优质海相烃源岩，其形成的油气最早富集在中央古隆起及其周围；伴随着中央古隆起带轴部的向东迁移和早白垩世末盆地西倾大单斜的定型，平凉组烃源岩在早白垩世生烃高峰期生成的天然气和早期古油藏裂解气，由中央古隆起带向北东方向发生二次运聚，最终在盆地中部奥陶系马家沟组风化壳中聚集成藏，即形成靖边大气田。

At each penton, a hole (φ=20〓) can be seen connecting the inside and the outside of the capsid, and there is a hole (φ=12〓) at each hexton and the center of 2-fold axis, so there are 132 holes in total at the surface of CSBV.

应用冷冻电镜技术和计算机三维结构重构的方法，我们测定了CSBV核衣壳的三维结构，分辩率为25 〓，病毒的核衣壳是按T=1（P=3）的对称结构排列二十面体，病毒表面比较光滑，有12个五邻体、60个六邻体的结构，每个五邻体的中央有孔洞，六邻体的中央也有孔洞，另外在2次轴的位置上也有孔洞，这样病毒共有132个孔洞，五邻体的孔洞的直径为20 〓，而六邻体和二次轴的孔洞的直径月为12 〓。

In the visual system, 5-HT/TPH-like immunoreactive neurons (ca.35 per hemisphere) were mainly situated between the optic lobe and lateral protocerebrum, the neurites of which either descended into the optic neuropils or ascended into the protocerebrum, thus possibly integrating the optic lobes and other brain regions.

TPH阳性神经元的类型、数目、分布位置、投射区域与5-HT基本相同。5-HT/TPH阳性神经元在视觉系统主要分布于视叶与侧前脑之间，每侧大约有35个，其轴突及分枝或下行进入视叶或上行进入前脑。5-HT/TPH阳性神经元在前脑分布于前脑背方、肯氏细胞两侧，大约有25个，轴突主要投射到蕈形体和中央复合体的广泛区域，另有个别神经元轴突下行投射进入视叶形成广泛分枝。

Inthe protocerebrum, 5-HT/TPH-like immunoreactive neurons (ca. 25) mainly distributed dorsalto the protocerebrum beside the Kenyon cells. Their axons directly projected into theprotocerebrum as well as the optic lobe.
