The structure of the annual-mean shallow meridional overturning circulation （SMOC） in the South China Sea （SCS） and the related water movement are investigated, using simple ocean data assimilation （SODA） outputs. The distinct clockwise SMOC is present above 400 m in the SCS on the climatologically annual-mean scale, which consists of downwelling in the northern SCS, a southward subsurface branch supplying upwelling at around 10°N and a northward surface flow, with a strength of about 1x 108 ma/s. The formation mechanisms of its branches are studied separately. The zonal component of the annual-mean wind stress is predominantly westward and causes northward Ekman transport above 50 m. The annual-mean Ekman transport across 18°N is about 1.2×106 m^3/s. An annual-mean subduction rate is calculated by estimating the net volume flux entering the thermocline from the mixed layer in a Lagrangian framework. An annual subduction rate of about 0.66×106 ma/s is obtained between 17° and 20°N, of which 87% is due to vertical pumping and 13% is due to lateral induction. The subduction rate implies that the subdution contributes significantly to the downwelling branch. The pathways of traced parcels released at the base of the February mixed layer show that after subduction water moves southward to as far as 1 I^N within the western boundary current before returning northward. The velocity field at the base of mixed layer and a meridional velocity section in winter also confirm that the southward flow in the subsurface layer is mainly by strong western boundary currents. Significant upwelling mainly occurs off the Vietnam coast in the southern SCS. An upper bound for the annual-mean net upwelfing rate between 10° and 15°N is 0.7×108 ma/s, of which a large portion is contributed by summer upwelling, with both the alongshore component of the southwest wind and its offshore increase causing great upwelling.

A detailed theoretical study on structural,electronic and optical properties of Mg2Si under the isotropic lattice deformation was performed based on the first-principles pseudopotential *** results show that the isotropic lattice deformation results in a linear decrease in the energy gap for the directΓ15-Γ1 and indirectΓ15-L1 transitions from 93%to 113%,while the indirect band gapΓ15-X1 increases from 93%to 104%and then reduces over 104%.When the crystal lattice is 93%compressed and 113% stretched,the magnesium silicide is a zero-gap ***,the isotropic lattice deformation makes the dielectric function shift and the static dielectric constant change.

In order to screen molecular markers linked to fertility restoring genes and further improve the breeding efficiency of restorer lines, in this study, wheat varieties 18A, 18B and 99AR144-1 were used as experimental materials to establish F2 fertility-segregating population. Plant quantitative trait ＂major gene ＋ polygene mixed mo- del＂ separation analysis method and simple sequence repeat （SSR） molecular markers were adopted for genetic analysis of four generations, including the parents （P~ and P2）, and hybrid （G and G） populations. The results show that AL-type fertility restoring gene is controlled by two pairs of additive-dominant-epistatic genes and addi- tive-dominant polygene; two primers linked to fertility restoring genes were selected by SSR molecular markers, including Xgwm95 on chromosome 2A and Barc61 on chromosome 1B, with the linkage distance of 15.0 cM and 18.0 cM, respectively. Based on verification, these two markers are reliable for distinguishing AL-type wheat ste- rile lines and restorer lines.

应用近红外透射检测技术在线检测苹果的糖度,分析运动速度对模型适用性的影响,在实验台分别以0,0.3,0.6,0.9m/s的切线速度检测苹果光谱,应用偏最小二乘法(PLS)建立苹果糖度的模型,得出最好的模型相关系数R为0.9386,校正标准差RMSEC为0.2894,最佳主因子数为4。研究结果表明:苹果运行速度对模型的预测结果有影响,用每个速度下的大量样品参与建模,可以有效地提高模型的稳健性,从而减少模型对水果运行速度的敏感性;当速度超过范围(阀值0.9m/s),模型的稳定性较差。

本研究基于日本主流社交平台Twitter中的真实网络话语,借助语料库文本分析工具KHcoder3.0,采用定性和定量相结合的研究方法,从语用学视角分析话语生成者使用的指称策略以及不同指称策略所体现出的移情和离情功能,从而探析日本主流社交平台对“中国留学生”这一群体形象的话语建构方式。研究发现中国留学生被日本主流社交平台构建出的群体形象主要为:1)受到日本政府的特殊优待者;2)侵犯知识产权的“间谍”;3)违法犯罪行为的参与者;4)就业的竞争者。此外,话语生成者会根据自身的情感倾向灵活选择语用站位和语言策略,在构建中国留学生积极向上的个人形象时,多使用专名化指称策略,达到群内化的效果,但这种积极正面的形象在语言层面上仅仅止步于某个个体;而在构建负面消极的群体形象时,多使用模糊的范畴化指称策略,从而将负面形象投射到整个中国留学生群体,达到距离化、他者化、群外化的效果。
