By.combining the α/γ interface migration and the carbon diffusion at the interface in Fe-C alloy., a mathematical model is constructed to describe the mixed-control mechanism for proeutectoid ferrite formation from austenite. In this model, the α/γ interface is treated as non-equilibrium interface, i.e., the carbon concentration of austenite at γ/α interface is obtained through theoretical calculation, instead of that assumed as the local equilibrium concentration. For isothermal precipitation of ferrite in Fe-C alloy., the calculated results show that the rate of interface migration decreases monotonically.during the whole process, while the rate of carbon diffusion from γ/α interface into austenite increases to a peak value and then decreases. The process of ferrite growth may.be considered as composed of three stages: the period of rapid growth, slow growth and finishing stage. The results also show that the carbon concentration of austenite at γ/α interface could not reach the thermody.amic equilibrium value even at the last stage of ferrite growth.

地方治理数智化变革引导基层治理变革的走向，是推进中国式现代化的重要基础。只有从中国式现代化视域审视地方治理数智化变革的基本逻辑，才能有效推动地方治理数智化的变革与创新。基于中国式现代化内涵的人民性、现代性、民主性和制度性叙事要求，新技术革命驱动下的地方治理数智化变革，不仅是整体智治价值理念、权责均衡关系结构的革新，而且是数据循证决策方式、体系再造底层规则的创新。然而，这一变革过程对技术理性的过度青睐导致了地方治理实践中对价值理性的忽视，极易引发工具支配的价值风险、责任缺位的伦理风险、技术至上的决策风险以及结构耗散的制度风险。倘若无法对这些风险进行有效的实践规制，那么技术应用的刚性一面将被发挥得淋漓尽致。为此，在地方治理数智化变革实践中，要通过政策环境持续优化、责任规约体系建构、人机交互系统重塑和技术治理规则增量，以纾解地方治理数智化变革的风险，使“赋能的智能技术”真正实现“高效能的治理”。

The X-ray.diffraction peak-shift method was introduced into the determination of deformation fault probability.(a) of Fe-Mn-Si alloy. with various Mn contents and thermomechanical cy.ling numbers. The precise lattice constants required were obtained by.numerical calculation instead of using standard sample without any.fault. The influence of internal stress on the determined a has been evaluated, and the caused relative error was determined as about 4% and thus negligible. The results show that the deformation fault probability.increases with decreasing Mn-content and increasing cy.le number, which are qualitatively.consistent with those results of Psf determined by.peak-broadening method.

A nanostructured surface lay.r can be formed in Ni metal treated by.surface mechanical attrition (SMA). The microstructure was investigated by.using optical microscope, X-ray.diffractometer and transmission electron microscope, respectively. Mechanical property.measurements indicate that the y.eld strength of the surface lay.r raises significantly.while the tensile strength somewhat changes and the elongation percentage reduces severely.compared with that of the inside lay.r. Meanwhile, y.eld-drop-like phenomenon occurs in the surface lay.r after SMA treatment. In order to compare the mechanical behavior of nanostructured materials with two phases, Fe-30Ni nanostructured alloy.was also investigated.

CK型陨石是一类高度氧化的碳质球粒陨石,金属/磁铁矿的比值接近零.与其它类型的碳质球粒陨石(岩石类型:1-3)不同,大多数CK型陨石在母体上经历了强烈的热变质过程(550-1270K),以4-6型为主.多项证据表明,CK和CV3型陨石具有成因联系.但是,两者在岩相结构和化学组成方面仍存在微小差异.因此,精细地区分和比较两者的地球化学特征对于验证CK-CV单一母体假说非常重要.Northwest Africa(NWA)13943是一块新发现的陨石,经历过较强烈的热变质作用.利用扫描电子显微镜和电子探针,确定了NWA 13943的岩石类型.并运用质谱分析技术,重点测定了NWA 13943陨石的全岩氧同位素和铬同位素组成.综合岩石结构、矿物化学成分、氧同位素异常(△^(17)O,△代表同位素分馏值)和铬同位素异常(ε^(54)Cr,ε表示样品中的同位素比值与标样中的同位素比值的相对偏差的10^(4)倍),CK和CV型陨石的母体可能形成于原行星盘中两个相似但不同的化学源区.

利用中国气象局发布的《区域性重要过程检测和评价业务规定》中对省级区域性暴雨过程的统计数据,NOAA气候预测中心降水、向外长波辐射(OLR)资料以及ERA-Interim再分析资料,探讨了10—20 d和30—60 d两类低频振荡对华南前汛期持续性暴雨的相对重要性,并基于尺度分离的水汽方程和垂直速度方程诊断了相关物理机制。结果表明,10—20 d准双周振荡对暴雨强度的影响较为显著,而30—60 d季节内振荡与暴雨持续时间相关较高,表明持续性暴雨事件与低频降水的发生和演变关系密切。通过对低频降水的热力和动力过程诊断,发现10—20 d低频降水的水汽来源主要为水汽平流过程,而导致水汽平流正距平的主要原因是10—20 d风场和背景水汽场的相互作用;而对于30—60 d低频降水而言,水汽平流和水汽辐合均为扰动水汽的累积做正贡献,但其中水汽平流更加重要,其主要来源于平均风场和30—60 d水汽场的相互作用。有利于两类低频降水发生的动力条件,即垂直上升运动,其主要源于平均风场和扰动涡度场相互作用引发的垂直涡度平流梯度。以上结果显示,提高模式中低频振荡与季节平均状态尺度相互作用的刻画能力,是改进预报持续性暴雨的关键。
