The hypertension model rats were induced with bi-kidney-bi-clip method, then the focal cerebral ischemia-reperfusion rat model was induced by reversible occlusion for a middle cerebral artery with a thread on the stroke prone renovascular hypertensive model rat. While the rats in sham operation group were operated without thread insertion. Shuigou (Du 26), bilateral Neiguan(PC 6) and bilateral Housanli (Zusanli, ST 36) were located according to"Atlas of Experimental Animal Acupoints" made by Hua's. Shuigou (Du26): 1 mm below nasal apex right on the Labium leporinum, be punctured 1 mm obliquely upward; Neiguan (PC 6): at the lateral palm of the forearm3 mm above wrist joint, between ulna and radius, be punctured 1 mm perpendicularly; Housanli (Zusanli, ST 36): under knee joint, 5 mm below the capitulum of fibula, be punctured 7 mm perpendicularly.

The Lower/Upper Cretaceous boundary in Songliao Basin is,therefore,between the Quantou and Denglouku formations,instead of between the Quantou and Qingshankou formations.2.The dark mudstones and shales in the Member 1 of Qingshankou Formation are of high organic carbon and low diasteranes contents.Organic geochemical characters are illustrated by biomarkers of 28,30-bisnorhopane and gammacerane,and positive excursion of kerogen isotopes.It is suggested that the dark mudstones and shales in the Member 1 of Qingshankou Formation are the products of lake anoxic period.It corresponds to the oceanic anoxic event at Cenomanian-Turonian boundary in Cretaceous.3.Based on the study of biostratigraphy,chronostratigraphy,magnetostratigraphy and event stratigraphy,a correlation of the lacustrine sequence to marine standard has been proposed,i.e.,the Quantou Formation corresponds to Cenomanian stage,Qingshankou Formation correlates to Later Cenomanian-Early Turonian,Yaojia Formation to Later Turonian-Coniacian,Nenjiang Formation to Santonian-Campanian.Sifangtai and Minshui Formations to Maastrichtian. 4.Analysis of lithology,lithofacies and microfossils of Cretaceous in Songliao Basin, shows that shore and shallow lake facies yield the most abundant microfossil groups,and the predelta and deltaic distributary plain facies rich in fossils as well.In the shore and shallow lake areas during the high level periods(such as Qingshankou and Nenjiang sedimentary periods),the lacustrine biota are of high diversity and high abundance.

Based on the relationship between the numerical aperture of the objective lens and scale pitch, this study chooses a suitable Plano-convex lenses available on the market, so as to approximate the diameter of the focusing spots to scale pitch. Also, by using the optical path of an optical encoder similar to the nanoscale, the changes in the surface profile of the scale can be measured directly, so as to obtain the two quadrature sinusoidal signals. By counting the zero crossing of these two quadrature sinusoidal signals and calculating the interpolation value of these two quadrature sinusoidal signals, the moving direction and moving displacement value of the scale can be obtained.
