The Interaction of Oblique Flexural Gravity Waves With a Small Bottom Deformation on a Porous Ocean-Bed： Green＇s Function Approach

The interaction of oblique incident water waves with a small bottom deformation on a porous ocean-bed is examined analytically here within the framework of linear water wave theory. The upper surface of the ocean is assumed to be covered by an infinitely extended thin uniform elastic plate, while the lower surface is bounded by a porous bottom surface having a small deformation. By employing a simplified perturbation analysis, involving a small parameter δ(<<1), which measures the smallness of the deformation, the governing Boundary Value Problem(BVP) is reduced to a simpler BVP for the first-order correction of the potential function. This BVP is solved using a method based on Green's integral theorem with the introduction of suitable Green's function to obtain the first-order potential, and this potential function is then utilized to calculate the first-order reflection and transmission coefficients in terms of integrals involving the shape function c(x) representing the bottom deformation. Consideration of a patch of sinusoidal ripples shows that when the quotient of twice the component of the incident field wave number propagating just below the elastic plate and the ripple wave number approaches one, the theory predicts a resonant interaction between the bed and the surface below the elastic plate. Again, for small angles of incidence, the reflected wave energy is more as compared to the other angles of incidence. It is also observed that the reflected wave energy is somewhat sensitive to the changes in the flexural rigidity of the elastic plate, the porosity of the bed and the ripple wave numbers. The main advantage of the present study is that the results for the values of reflection and transmission coefficients obtained are found to satisfy the energy-balance relation almost accurately.

县域教育的兜底功能:社会基础与实现路径

县域教育深嵌在县域社会之中,既要承担一般化的教育功能,还要回应县域社会独特的教育需求。由于县域社会主要是乡村社会,当前乡村社会从整体走向碎片、农民家庭从完整走向分割、隔代教育的社会功能不齐全、教育城镇化加剧乡村学校衰败等社会变迁,使得县域教育中家庭主体、社会主体缺位,导致一些重要的教育功能无法实现,使县乡的孩子们的权利受到侵害,给其成长带来不良影响。为此,县乡学校要对县乡孩子们的教育进行权利和责任兜底。要实现教育兜底功能,县域教育就要集中力量办好乡校、县中及县域职业学校要向多中心教育目标转型,以确保县乡的孩子们有平等的机会和权利通过县域教育走出县乡,成为有知识、懂规范、人格健全、适应社会的人。

A novel steady-state productivity equation for horizontal wells in bottom water drive gas reservoirs

It is known that there is a discrepancy between field data and the results predicted from the previous equations derived by simplifying three-dimensional（3-D） flow into two-dimensions（2-D）.This paper presents a new steady-state productivity equation for horizontal wells in bottom water drive gas reservoirs.Firstly,the fundamental solution to the 3-D steady-state Laplace equation is derived with the philosophy of source and the Green function for a horizontal well located at the center of the laterally infinite gas reservoir.Then,using the fundamental solution and the Simpson integral formula,the average pseudo-pressure equation and the steady-state productivity equation are achieved for the horizontal section.Two case-studies are given in the paper,the results calculated from the newly-derived formula are very close to the numerical simulation performed with the Canadian software CMG and the real production data,indicating that the new formula can be used to predict the steady-state productivity of such horizontal gas wells.

Estimation of Turbulent Kinetic Energy Dissipation Rate in the Bottom Boundary Layer of the Pearl River Estuary

A structure function approach is applied to estimate the turbulent kinetic energy （TKE） dissipation rate in the bottom boundary layer of the Pearl River Estuary （PRE）. Simultaneous measurements with an acoustic Doppler velocimeter （ADV） supplied independent data for the verification of the structure function method. The results show that, 1） the structure function approach is reliable and successfully applied method to estimate the TKE dissipation rate. The observed dissipation rates range between 8.3 ×10^-4 W/kg and 4.9× 10^-6 W/kg in YM01 and between 3.4×10^-4 W/kg and 4.8×10^-7 W/kg in YM03, respectively, while exhibiting a strong quarter-diurnal variation. 2） The balance between the shear production and viscous dissipation is better achieved in the straight river. This first-order balance is significantly broken in the estuary by non-shear production/dissipation due to wave-induced fluctuations.

上、下行效应对洱海浮游植物优势功能群的影响

浮游动物牧食、水温及营养可利用性均可影响优势浮游植物功能群的转变,但这些驱动因素的交互作用尚不清楚。为了解云南高原湖泊——洱海浮游植物优势功能群的分布特征及其主要驱动因素,于2018年1月2020年12月进行月度采样,结合聚类分析、方差分析和冗余分析等,分析驱动浮游植物优势功能群转变的主要因素。结果表明,共鉴定浮游植物7门96属,划分为27个浮游植物功能群,其中优势功能群有15个。聚类分析结果表明,根据浮游植物功能群密度数据可将优势功能群转变过程分为3个由不同类型藻类主导的时期(S期、M期和P期),其中S期(为期18个月)以功能群S1和H1(代表藻为假鱼腥藻、浮丝藻和长孢藻等丝状蓝藻)为主,M期(为期10个月)以功能群M(微囊藻群体)为主,P期(为期8个月)以功能群P和M(脆杆藻和单个微囊藻等)为主。RDA分析及变差分解分析结果表明,卡尔森营养状态指数(TSI)(主要是总磷)是影响以丝状藻类为主的浮游植物功能群的主要驱动因素,TSI和水温是影响以微囊藻为主的浮游植物功能群的重要驱动因素。因此,在富营养化初期湖泊中,降低湖泊营养负荷是首要任务。同时可以考虑增加浮游动物丰度的策略,以增强浮游动物在削减丝状蓝藻或微囊藻生物量(下行效应)中的作用和重要性。

Simulation of Random Waves and Associated Laminar Bottom Shear Stresses

This work presents a new approach for simulating the random waves in viscous fluids and the associated bottom shear stresses. By generating the incident random waves in a numerical wave flume and solving the unsteady two-dimensional Navier-Stokes equations and the fully nonlinear free surface boundaiy conditions for the fluid flows in the flume, the viscous flows and laminar bottom shear stresses induced by random waves axe determined. The deterministic spectral amplitude method implemented by use of the fast Fourier transform algorithm was adopted to generate the incident random waves. The accuracy of the numerical scheme is confirmed by comparing the predicted wave spectrum with the target spectrum and by comparing the nanlerical transfer function between the shear stress and the surface elevation with the theoretical transfer function. The maximum bottom shear stress caused by random waves, computed by this wave model, is compared with that obtained by Myrhaug＇ s model （1995）. The transfer function method is also employed to determine the maximum shear stress, and is proved accurate.

海底地震仪远震记录接收函数反演——以南海西南次海盆为例

由于海底环境和海底地震仪（OBS）结构的特殊性,用OBS远震记录进行接收函数岩石圈反演研究因为存在一定的困难,所以还很少见.在深入分析问题的基础上,以国产I-4C型宽频带OBS在南海西南次海盆记录的天然地震为实例,我们将傅里叶变换和小波变换相结合以压制海底地震仪记录中的非平稳干扰,获得了信噪比较高、震相清晰的地震记录,进而成功开展了远震记录的岩石圈结构接收函数反演.主要结论是：（1）OBS接收函数的求取是可行的,关键是压制非平稳干扰.（2）西南次海盆的Moho面埋深为海底下10～12km（地壳厚6～8km）,沉积物厚度为1～2km,浅部地壳存在低速区,与沉积物和海底扩张停止后的岩浆喷发产生的岩石碎屑和裂隙有关.（3）在扩张脊中央Moho面上方6～12km存在S波低速区,推测扩张中心可能存在下地壳熔融或岩浆房,在17～30km区间S波速度呈负梯度,我们认为扩张中心更深的地方存在热物质的供给.
