| 1 | Composition, origin and weathering process of surface sediment in Kumtagh Desert, Northwest China显示文摘Kumtagh 沙漠是在中国的八最大的沙漠之一,但是因为存取的困难,以前糟糕调查我们的学科交差的学习。在这份报纸, 33 件代表性的表面沉积样品从在实验室荒芜、分析的 Kumtagh 被收集获得重矿物质部件和 geochemical 元素内容。结果证明重矿物质的各种各样的类型在这些样品是在场的,与绿帘石和角闪石的高水平。Si 和艾尔收起化学作文的大部分。与上面的大陆人外壳(UCC ) 的 geochemical 元素的平均作文相比,除了 Si 和 Ca,所有元素被弄空到某个度;Fe, Mg, Ca, P, Ti 和 Mn 在他们的内容有高关联系数。矿物质和 Kumtagh 荒芜的沉积的 geochemical 作文在 Altyn Tagh 山脉和 Taklamakan 沙漠的附近与 Altyn Tagh 山脉,和冲积/洪水的扇子的表面沉积的岩石的有类似,显示 Kumtagh 荒芜的沉积的一主要来源位于 Altyn Tagh 山脉。在 Aqik 山谷和 Shule 河的更低的活动范围的冲积沉积物和湖沉积是容易的被侵蚀并且搬运由强壮在东北弯屈进 Kumtagh 沙漠,形成沙漠的另一来源扔。一张 A-CN-K 第三的图证明由 Na 和 K 的损失捱过的弱度化学药品发生在这些沉积,而 A-CNK-FM 第三的图建议 Fe 和 Mg 经历了重要化学区别。物理捱过过程为 mafic 矿物质在好粒子引起容易的侵蚀和丰富,这样粗糙的荒芜的沙粒子能相对在 Fe 和 Mg 被弄空。在经历不太化学的捱过的干旱区域的沉积的矿物质和 geochemical 作文被物理捱过主要影响。 | XU Zhiwei LU Huayu ZHAO Cunfa WANG Xianyan SU Zhizhu WANG Zhenting LIU Hongyi WANG Lixin LU Qi | 2011 | Journal of Geographical Sciences2011，21，6： | 13 |
| 2 | Effects of electric/magnetic impact on the transient fracture of interface crack in piezoelectric-piezomagnetic sandwich structure: anti-plane case显示文摘Due to the incompatibility of the interlaminar deformations,the interface debonding or cracking usually happens in a layered magnetoelectric(ME)structure under an applied load.In this paper,the transient responses of the anti-plane interface cracks in piezoelectric(PE)-piezomagnetic(PM)sandwich structures are studied by the standard methods of the integral transform and singular integral equation.Discussion on the numerical examples indicates that the PE-PM-PE structure under electric impact is more likely to fracture than the PM-PE-PM structure under a magnetic impact.The dynamic stress intensity factors(DSIFs)are more sensitive to the variation of the active layer thickness.The effects of the material constants on the DSIFs are dependent on the roles played by PE and PM media during the deformation process. | Xing ZHAO Zhenghua QIAN Jinxi LIU Cunfa GAO | 2020 | Applied Mathematics and Mechanics(English Edition)2020，41，1： | 3 |

| 6 | Closed-Form Solution for a Circular Nanohole with Surface Effects Under Uniform Heat Flux显示文摘This paper investigates the steady-state thermoelastic problem of a circular nanohole embedded in an infinitely large elastic plane subjected to a uniform far-field heat flux.A lowly conductive surface model is used to account for the effects of surface phonon scattering,while the complete Gurtin–Murdoch model is utilized to characterize the effects of surface tension and surface elasticity.The closed-form solution to the temperature and stress field surrounding the hole is derived in the context of complex variable methods.Several numerical examples are presented to analyze the influence of surface effects on thermal stress fields.It is shown that surface effects induce notable increases in normal and shear stresses around the hole.Specifically,all three stress components(hoop,normal,and shear)in the vicinity of the hole exhibit substantial augmentation with increasing surface tension and surface modulus.In particular,it is found that the presence of surface effects amplifies the variation in stress gradients and intensifies stress concentration around the hole. | Jieyao Tang Jieyan Zhao Haibing Yang Cunfa Gao | 2024 | Acta Mechanica Solida Sinica2024，37，1： | 0 |
