A gear position decision method used in automated mechanical transmission is introduced. The algorithm of the mechod is composed of a driving environment and driver's intention estimator, the shift schedules suit for each typical driving environment and driver's intention situation, and an inference ligic to determine the most proper gear position for the present situation. The estimator identifies the driving environment and driver's intention features which are divided into some typical models. Based on the identified results, the algorithm works out the best gear position. It just simulates the course of driver's making gear position decision when driving a automobile with manual transmission. The test results show that the automated mechanical transmission with the method gives less unnecessary shifting and more proper gear position than common shift schedules.

The Qinling Orogenic Belt is divided commonly by the Fengxian-Taibai strike-slip shear zone and the Huicheng Basin into the East and West Qinling mountains, which show significant geological differences after the Indosinian orogeny. The Fengxian-Taibai fault zone and the Meso-Cenozoic Huicheng Basin, situated at the boundary of the East and West Qinling, provide a natural laboratory for tectonic analysis and sedimentological study of intracontinental tectonic evolution of the Qin- ling Orogenic Belt. In order to explain the dynamic development of the Huicheng Basin and elucidate its post-orogenic tecton- ic evolution at the junction of the East and West Qinling, we studied the geometry and kinematics of fault zones between the blocks of West Qinling, as well as the sedimentary fill history of the Huicheng Basin. First, we found that after the collisional orogeny in the Late Triassic, post-orogenic extensional collapse occurred in the Early and Middle Jurassic within the Qinling Orogenic Belt, resulting in a series of rift basins. Second, in the Late Jurassic and Early Cretaceous, a NE-SW compressive stress field caused large-scale sinistral strike-slip faults in the Qinling Orogenic Belt, causing intracontinental escape tectonics at the junction of the East and West Qinling, including eastward finite escape of the East Qinling micro-plate and southwest lateral escape of the Bikou Terrane. Meanwhile, the strike-slip-related Early Cretaceous sedimentary basin was formed with a fight-order echelon arrangement in sinistral shear zones along the southern margin of the Huicheng fault. Overall during the Mesozoic, the Huicheng Basin and surrounding areas experienced four tectonic evolutionary stages, including extensional rift basin development in the Early and Middle Jurassic, intense compressive uplift in the Late Jurassic, formation of a strike-slip extensional basin in the Early Cretaceous, and compressive uplift in the Late Cretaceous.

目的:探讨577 nm阈值下微脉冲激光(SML)治疗中心性浆液性脉络膜视网膜病变(CSC)的效果与黄斑结构变化。方法:回顾性分析2017年5月-2020年5月在本院确诊的80例CSC患者。按照治疗方案的不同将患者分为微脉冲激光治疗组(观察组,n=40)和传统黄色激光治疗组(对照组,n=40)。观察组采用577 nm SML治疗,对照组采用传统黄色激光治疗。治疗前后采用统一主观视觉质量问卷评价两组患眼视物变暗情况,观察最佳矫正视力(BCVA),SD-OCT检测黄斑中心凹结构参数:视网膜厚度(CRT)、上皮层厚度(CNT)、外核层厚度(ONT)、脉络膜厚度(SFCT)、椭圆体带(EZ)、嵌合体带(IZ);相关性分析视力情况与黄斑区结构变化关系。结果:治疗后,两组急性期患者视物变暗均消失,慢性期患者视物变暗有所改善,两组间比较,差异均无统计学意义(P>0.05)。治疗后,两组BCVA较治疗前均有显著改善,差异均有统计学意义(P<0.05)。治疗后,两组CRT、SFCT较治疗前均有改善,差异均有统计学意义(P<0.05)。治疗后,观察组急性期和慢性期的CRT均显著低于对照组,差异均有统计学意义(P<0.05)。治疗后,观察组急性期和慢性期EZ与IZ与治疗前结构变化比较,差异均有统计学意义(P<0.05)。对照组急性期治疗后EZ和IZ与治疗前比较,差异均有统计学意义(P<0.05);对照组慢性期治疗后IZ与治疗前比较,差异有统计学意义(P<0.05)。Pearson相关性分析显示BCVA(logMAR)与CRT、SFCT参数均呈正相关(P<0.05)。Spearman相关性分析显示,BCVA(logMAR)与EZ、IZ完整程度均呈负相关(P<0.05)。结论:对于急性期CSC患者,577 nm SML与传统黄色激光均使患眼视物变暗消失,而对慢性期CSC患者视物变暗有所改善,577 nm SML可快速改善BCVA,改善黄斑区结构和视觉症状,疗效显著且安全。

Paleozoic cherts from the Mianl and the Erlangping ophiolite zones of the Qinling orogenic belt are characterized by low Si/Al ratios (52.14-683.52 in the Mianle cherts, 12.29-58.62 in the Erlangping cherts), Fe2O3 (0.01-0.35 and 0.02-1.24) and high Al2O3/(Al2O3+Fe2O3) ratios (0.82-0.99 and 0.83-0.99). The negative correlation between Si2O and Al2O3 in the cherts reflects the important role of terrigenous components. The Erlangping cherts have Lan/Cen=0.9-1.15 and Ce/Ce*=0.95-1.15 with low contents of V, Ni and Cu, consistent with those of cherts forming on the continental margin. In contrast, the Ce/Ce* ratios of the Mianle cherts range from 0.71 to 1.18 and Lan/Cen from 0.88 to 1.43 with slightly high V, Ni and Cu, which are similar to cherts found in the mid-ocean ridges and pelagic basins. Combined with the features of basic lavas associated with the cherts, it is suggested that during the Paleozoic, when the back-arc basin represented by the Erlangping ophiolite commenced shrinking in size in the mid-Ordovician, the southern Qinling was still in an extensional regime and finally grew into a new limited oceanic basin in the early Carboniferous.
