Based on the well-logging data of typical wells of Zhijin,Panxian and Weining areas in western Guizhou,the well-logging data GR of late Permian coal-bearing strata were processed and wavelet transform technique was used to carry out the sequence stratigraphy division and *** study mainly focuses on the controlling effects which Milankovitch had on high frequency sequence,Milankovitch cycle can be used as a ruler of sequence stratigraphy division and correlation to ensure the scientifcity and the unity of sequence stratigraphy *** to well-logging signal of the ideal Milankovitch cycle,the corresponding relation between the wavelet scales and the cycles is determined by wavelet *** analyzing analog signals of subsequence sets to search the corresponding relation between various system tracts and the features of time-frequency,the internal features of wavelet transform scalogram could be made *** to ideal model research,features of Milankovitch curves and wavelet spectrum can be seen clearly and each well can be classifed into four third-order sequences and two system *** the same time Milankovitch cycle can realize the division and correlation of stratigraphic sequence in a quick and convenient way.

Purpose:To evaluate the influence of corneal ablation patterns on the prediction error after cataract surgery in postmyopic-LASIK ***:Eighty-three post-myopic-LASIK eyes of 83 patients that underwent uneventful cataract surgery were retrospectively *** postoperative spherical equivalence(SE)was calculated for the implanted lens using the Haigis-L and Barrett True-K *** error at one month postsurgery was calculated as actual SE minus predicted *** each eye,area and decentration of the ablation zone was measured using the tangential curvature *** associations between prediction errors and corneal ablation patterns were ***:The mean prediction error was-0.83±1.00 D with the Haigis-L formula and-1.00±0.99 D with the Barrett True-K *** error was positively correlated with keratometry(K)value and negatively correlated with ablation zone area using either formula,and negatively correlated with decentration of the ablation zone using the Barrett True-K formula(all P<0.05).In the K<37.08 D group,prediction error was negatively correlated with decentration of the ablation zone with both formulas(all P<0.05).Multivariate analysis showed that with the Haigis-L formula,prediction error was associated with axial length(AL),K value and decentration,and with the Barrett True-K formula,prediction error was associated with AL and decentration(all P<0.05).Conclusion:A flatter cornea,larger corneal ablation zone and greater decentration will lead to more myopic prediction error after cataract surgery in post-myopic-LASIK eyes.

To the editor： A 12-month-old child was admitted to our department for treatment regarding his inner canthus mass. His parents complained epiphora and mucopurulent discharge of the left eye after formation of a mass located in the left lower eyelid and medial canthus over 3 months （Figure 1A）. The mass increased in size gradually. This child was diagnosed as acute dacryocystitis and underwent probing for two times in another hospital. When he was 6 months old, he also had a similar mass which had resolved spontaneously. No history of sinus or systemic disease, trauma, or facial surgery was found.

The Shanwang Basin is a small Cenozoic sedimentary basin located in Linqu county, Shandong *** Shanwang Formation, especially the diatomaceous shale member, contains diverse and finely preserved flora and fauna fossils （Fig. 1）. Previous paleontological study and radiometric dating show that it was formed in the Miocene. However, on the precise age of the formation, there are such different opinions as Late Miocene, Middle Miocene, Early stage of Middle Miocene, etc.

Red beds are not entirely red sometimes, in which grey-green spheroids or irregular spots can be found. However, the formation mechanism of grey-green spheroids or irregular spots in red beds is not clear so far. Samples taken from well JK1 in Jiaozhou area of Jiaolai Basin displayed that the reduction spheroids have more Vanadium (V) element, less TFe3O4 and Lead (Pb) element, almost the same content of other elements such as FeO and so on, comparing the red parts of the samples. The existence of organisms can explain the existence of green reductive spheres in the red beds formed under the oxidation environment.
