The Bamiléké Plateau represents a key domain in the understanding of the geodynamics associated with the central Cameroon shear. The study aimed to highlight the subsurface architecture of the plateaus basement setting with focus on high potential areas for hydrogeological and mining development projects. To this end, geological field observations were carried out. Since the structures sought were near-surface, a separation approach based on the upward continuation method was applied to the Bouguer anomaly grid. A set of processing techniques, including vertical derivative or DZ, analytical signal or SA and categorization of gravity signatures, was applied to generate the residual map. The synthesis geological model, obtained from analysis and interpretation of the various transformed maps and 2.5D modeling of two gravity profile. P1 and P2 highlights the following features: 1) intrusions of steep-sided granitic batholiths from Dschang to Bandjoun (profile.P1), increasing in width from NW (Dschang) to se (Bandjoun);2) larger volume batholiths with moderate sides located at Bafang and Bangangté (profile.P1). These plutonic massifs were weakened by brittle.deformation, which favored the emplacement of phonolite or anorthosite dykes within them. The emplacement of these dykes was accompanied by compressional faults with high dip between Dschang and Bandjoun and extensional faults with medium dip between Bafang and Bangangté. These fault zones (trending N85E to N95E) are ideal for hydrogeological investigations in a basement setting, as well as a series of dyke networks that could potentially be preferred zones for the circulation and accumulation of useful substances. The resulting geological sections P1 and P2 highlight the influence of granitic intrusions in the geological system of the study area, as well as the structural control associated with the various dyke intrusions. All the models obtained can serve as fundamental references for hydrogeological and mining e

为实现Cd污染农田稻米安全生产,采用田间试验,以五优1179和丝香1号作为供试材料,于水稻孕穗期和灌浆期喷施硅(Si)、硒(se)阻隔剂,探讨其对稻谷产量、农艺性状、糙米Cd含量及不同部位对Cd吸收和转运的影响.结果表明:较空白相比,喷施流体硅后五优1179和丝香1号的稻谷产量分别增产9.02%和2.03%,喷施螯合硒后五优1179增产7.27%,丝香1号的稻米产量下降5.40%;不同处理下丝香1号的剑叶长度均大于五优1179,株高范围为110~112cm;叶面喷施流体硅可使品种五优1179和丝香1号的糙米Cd含量降至0.181,0.186mg/kg,喷施螯合硒后丝香1号的糙米Cd含量达0.169mg/kg,五优1179的糙米Cd含量由0.487mg/kg降至0.202mg/kg,未达《食品安全国家标准》(GB 2762-2022)中糙米Cd限量标准(0.2mg/kg);喷施流体硅后两种水稻不同部位Cd含量顺序为根>其他节>第一节>其他叶>剑叶>颖壳>穗轴>糙米,施用螯合硒后不同部位Cd含量变化主要表现在穗轴>颖壳.外源喷施流体硅和螯合硒均能显著降低两种水稻体内Cd含量(P<0.05),根、茎和糙米中Cd含量显著下降,TF_(穗轴/剑叶)受到抑制.而相较于喷施流体硅,喷施螯合硒后水稻穗轴Cd含量和TF_(穗轴/剑叶)上升,TF颖壳/穗轴明显下降;相关性分析结果表明,糙米Cd含量与根和茎Cd含量呈显著正相关(P<0.01),与其他叶Cd含量呈显著负相关(P<0.05).流体硅不但有利于提高稻米产量,还能降低糙米Cd含量,且经济成本相对较低,建议在该区域Cd污染安全利用类农田推广使用.

本文通过拓展BLT(Baum-Liu-Tesche)方法,计算了复杂结构腔体的屏蔽效能(Shielding Effectiveness,se). BLT方法最初被用于分析传输线模型,后被拓展到计算腔体屏蔽效能,然而其局限于计算矩形腔体和圆柱腔体的屏蔽效能,无法分析更加复杂的腔体结构.本文将BLT方法与数值方法相结合,同时利用机器学习的回归方法,将其拓展到复杂腔体结构的屏蔽效能计算中.本文首先计算了腔体二维截面的特征模;然后,基于电磁波传播规律建立了等效电路网络结构,结合BLT方法获得腔体屏蔽效能的频域响应分布;最后,利用机器学习方法训练支持向量回归模型(Support Vector Regression,SVR),修正频域响应幅值,得到腔体目标的屏蔽效能.本文采用了3种不同结构的腔体对提出的方法进行了验证,频率范围为0.1~3 GHz.以商业软件仿真得到的结果为标准,本文提出的方法可以在85%的置信度条件下,实现均方根误差小于3,同时计算速度相比商业软件提升80倍以上.
