广西中南部汉、壮语共享两个特征,即量词重叠(CL+CL)表任指、“对”有存在动词、处所/时间介词的功能,模式语都是壮语,汉语复制了其语法功能。前一共享特征在如下结构的演变中获得,即:V_(1)+CL+哪,CL+那+V_(2)>V_(1)+CL,CL+V_(2)>V_(1)+CL+CL+V_(2),触发演变的语境是五言壮语歌谣。后一共享特征的来源是:壮族人意识到壮语的“V+te:■^(1)”与汉语官话的“V+对”是相对应的,推测出壮语的te:■^(1)就是官话的“对”,他们将壮语“te:■^(1)+N”结构类推为壮式官话的“对+N”。随着壮式官话“对+N”在宜州官话中的扩展,导致“对”获得存在动词、处所/时间介词的功能。

Compared with well-developed free space polarization converters, polarization conversion between te and TM modes in the waveguide is generally considered to be caused by shape birefringence, like curvature, morphology of waveguide cross section and scattering. Here, we study the polarization conversion mechanism in 1-THz-FSR X-cut lithium niobate microrings with multiple-resonance condition, that is the conversion can be implemented by birefringence of waveguides,which will also introduce an avoided-mode crossing. In the experiment, we find that this mode crossing results in severe suppression of one sideband in local nondegenerate four-wave mixing and disrupts the cascaded four-wave mixing on this side. Simultaneously, we propose one two-dimensional method to simulate the eigenmodes(te and TM) in X-cut microrings, and the mode crossing point. This work will provide one approach to the design of polarization converters and simulation for monolithic photonics integrated circuits, and may be helpful to the studies of missed temporal dissipative soliton formation in X-cut lithium niobate rings.

To understand the earthquake characteristics in Xinfengjiang (XFJ for short) reservoir area, we collected the small earthquakes occurred in the area from 1961 to 1999. We segmented this 40-year period, parted the research region and calculated the composite fault plane solution of each block, disscussed the effect characteristics of stress field of water pressure using Mohrs stress circle. The final result shows that the main rupture pattern was very different before and after the M = 6.1 main shock, changing from strike slip to normal rupture. The maximum principal stress axes of composite fault plane solutions are characterized by synchronous change with water level.

目的·观察睡眠呼吸暂停综合征(sleep apnea hypopnea syndrome,SAS)对双相障碍(bipolar disorder,BD)患者不同发作状态下睡眠分期的影响。方法·收集210例18~65岁的健康对照及年龄相当的235例BD患者,根据BD患者的发作状态将其分为抑郁相、躁狂相和混合相。运用基于心肺耦合分析的睡眠质量评估系统,采集受试者的睡眠时间结构、睡眠体位、睡眠心率等指标;根据睡眠呼吸紊乱指数(apnea-hypopnea index,AHI)是否≥5次/h确定每组对象是否患有SAS,并针对BD的发作状态和是否患有SAS进行两因素多元方差分析。结果·SAS对抑郁相BD患者的快速眼动(rapid eyes movement,REM)睡眠时间有显著延长作用(P=0.000),对躁狂相BD患者的熟睡时间有显著缩短作用(P=0.011)。另外,躁狂相BD患者的睡眠期间(熟睡、浅睡及REM睡眠期)心率增快在3种发作状态中最为显著(P=0.000),仰卧位对躁狂相BD患者的SAS症状加重的影响在3种发作状态中最为显著(P=0.002)。结论·SAS对BD患者不同发作状态下的睡眠分期可产生不同的影响。
