研究目的:桥梁勘测方案设计的好坏直接决定施工图的质量,在工期短、人员少的不利局面下,不能保质保量地按时完成勘测任务。本文通过研究铁路桥梁勘测信息处理系统,旨在解决方案设计时遇到的难题,为实现勘测信息自动处理提供技术支持。研究结论:(1)引进区域码描述断链,打破断链不能上桥的规定;(2)提出连续梁在曲线上布置的方法,在手算弯道布置计算流程中增加迭代过程,实现了长桥在多个曲线上的一次性布置;(3)将孔跨布置过程抽象为计数器累加计算,加快了方案比选的进度;(4)由线路平面图反算墩台里程坐标,完成了桥梁与线路专业的无缝过渡;(5)设计递归算法解决绘图时文字重叠问题,减少了人工修改;(6)该系统优化的方案是合理的、可行的,其计算速度快、成果输出规范,可以较好地应用于大规模铁路桥梁勘测设计中。

5-Alkenyl-2,2-butylidene-1,3-dioxane-4,6-diones were synthesized by the Knoevenagel condensation reaction of aromatic aldehydes with 2,2-butylidene-1,3-dioxane-4,6-dione using o-phthalimide-N-sulfonic acid as catalyst, without solvent under ultrasonic irradiation. The present method has some notable advantages such as mild reaction conditions, short reaction times, less catalyst dosage and high yields with the green aspects by avoiding toxic catalysts and solvents. Further, the catalyst can be reused for five times without any noticeable decrease in the catalytic activity.

AIMTo conduct a comparative study of effectiveness of silicone hydrogel contact lens and hydrogel contact lens, which are used in patients after laser-assisted subepithelial keratomileusis (LASEK).METHODSSixty-three patients (121 eyes) with a spherical equivalent ≤-5.0 D were chosen after undergoing LASEK in 2012 at Guangdong General Hospital. They were randomly divided into 2 groups. The silicone hydrogel group included 32 cases (61 eyes) that wore silicone hydrogel contact lenses for 4-6d after the operation, while the hydrogel group included 31 cases (60 eyes) who wore hydrogel contact lenses for 4-6d after the operation. Patients' self-reported postoperative symptoms (including pain, photophobia, tears, and foreign body sensation) were evaluated. The healing time of the corneal epithelium, the visual acuity of patients without contact lens after epithelial healing, and the incidence of delayed corneal epithelial shedding were also assessed. The follow-up time was *** symptoms were milder in the silicone hydrogel group than in the hydrogel group. There were significant differences in pain, foreign body sensation, and photophobia between the 2 groups (P0.05). The healing time of the corneal epithelium in the silicone hydrogel lens group was markedly shorter than that in the hydrogel group (4.07±0.25 vs 4.33±0.82d, t=2.43, P=0.02). Visual acuity without contact lenses after healing of the corneal epithelium was better in the silicone hydrogel group compared with the hydrogel group (χ2=7.76, P=0.02). There was no significant difference in the occurrence of delayed corneal epithelial shedding between the 2 groups (P>0.05).CONCLUSIONPatients with LASEK using silicon hydrogel contact lenses had less discomfort and shorter corneal epithelial healing time compared with those using hydrogel contact lenses,

Built in the tenth year during the reign of Emperor Qianlong (1745), located at the southern slope of Jingyi Garden on Fragrant Hills Park of Beijing, Qiyunlou Garden is one of the 28 scenic spots of Jingyi Garden. Its excellent geographical condition of “leaning against the towering mountain rocks on the right and overlooking the distant mountain hills on the left” and good natural environment of “lush growth of plants and quiet and secluded atmosphere” make this one of the favorite gardens of Emperor Qianlong. The organic combination of the tranquil mountain scenery, the agile stream and the building creates a poetic artistic conception that is broad, deep, quiet and elegant. This paper analyzes the value and historical changes of Qiyunlou Garden, and explores the garden design techniques of Qiyunlou Garden from the perspectives of site selection, stone arrangement, water feature design and plant configuration.

Mineral apatite compounds have attracted significant interest due to their chemical stability and adjustable hexagonal structure,which makes them suitable as new photovoltaic functional *** band gap of natural apatite is ~5.45 eV,and such a large value limits their applications in the field of catalysis and energy *** this research,we designed a method to narrow the band gap via the tetrahedral substitution effect in apatite-based *** density functional theory(DFT) and experimental investigation of the electronic and optical properties revealed that the continuous incorporation of [MO_(4)]^(4-) tetrahedrons(M=Si,Ge,Sn,and Mn) into the crystal lattice can significantly reduce the band *** particular,this phenomenon was observed when the[MnO_(4)]^(4-) tetrahedron replaces the [PO_(4)]^(4-) tetrahedron because of the formation of a Mn 3 d-derived conduction band minimum(CBM) and interacts with other elements,leading to band broadening and obvious reduction of the band *** approach allowed us to propose a novel scheme in the band gap engineering of apatite-based compounds toward an entire spectral range modification.
