We present a detailed investigation of the specific heat of Ca3（Ru1-xMx）2O7 （M = ti, Fe, Mn） single cry.tals. Depending on the dopant and doping level, three distinct regions are present： a quasi- two-dimensional metallic state with antiferromagnetic （AFM） order formed by.ferromagnetic bilay.rs （AFM-b）, a Mott insulating state with G-ty.e AFM order （G-AFM）, and a localized state with a mixed AFM-b and G-AFM phase. Our specific heat data provide deep insights into the Mort transitions induced by.ti and Mn doping. We observed not only.an anomalous large mass enhancement, but also an additional term in the specific heat, i.e., C ∝ t2, in the localized region. the C ∝ t2 term is most likely.due to long-wavelength excitations with both FM and AFM components. A decrease in the Deby. temperature is observed in the G-ty.e AFM region, indicating lattice softening associated with the Mott transition.

At present, aero-engines face a major need to widen the ignition envelope. In order to provide a technical support to expand the high altitude ignition envelope of aero-engines, in this article we propose a novel ignition technology. i.e., "precombustion plasma jet ignition technology.. In this paper, we also design a pre-combustion plasma jet igniter. Its discharge characteristics, jet characteristics, and ignition effects are studied. the results show that increasing the equivalent ratio of jet gas can enhance the discharge stability.and increase the duty.cy.le. At the same time, it can reduce working power and energy.consumption. the increase of equivalent ratio in jet gas can enhance the length and ignition area of plasma *** the process of ignition, the pre-combustion plasma jet igniter has obvious advantages, suchn as shortening the ignition delay.time and enlarging the ignition boundary. When the airflow velocity.is 39.11 m/s and the inlet air temperature is80℃, compared with the spark igniter and the air plasma jet igniter, the pre-combustion plasma jet igniter has an ignition boundary.that is expanded by.319.8% and 55.7% respectively.

按照周培源教授关于研究湍流数值模拟建模时必须分析和求解脉动速度场的思想,该研究基于第一性原理,系统地建立了基于时空低维最优动力系统的多尺度可压缩湍流数值模拟方法(LMS方法),并将其应用于多次冲击Richtmy.r-Meshkov问题的数值模拟中,首次得到了可压缩湍流的中尺度流场和不同于DNS近似解的湍流近似解.数值结果表明,LMS方法可以用较少的网格获得更精确的湍流近似解.首先解决了研究中遇到的几个问题,为LMS方法的构建铺平了道路.这些问题是:基于湍流的物理特性,提出了湍流大、中、小尺度分解的新概念;找到了box滤波空间相关性的计算方法;指出了湍流建模理论中长期存在的逻辑错误,提出了多尺度湍流模型的概念;讨论了湍流封闭问题的本质和关键,给出了克服湍流封闭问题的数值方法.采用box滤波方法/空间网格平均方法且在大尺度网格的意义下,LMS方法的本质是一种将RANS、LES、DES和DNS等湍流数值模拟方法统一的全新湍流数值模拟方法.需要指出的是,LMS方法也可以作为湍流模型研究的辅助工具,以检验SGS尺度方程/脉动方程中各项所对应的湍流模型是否正确.

In this work, the influences of alumina addition on cristobalite cry.tallization and properties of injec- tion molded silica-based ceramic cores were investigated. X-ray.diffraction （XRD） was used to characterize phase transformations in the samples, and the XRD result indicated that the addition of alumina pro- moted cry.tallization of fused silica during sintering at 1180-1220 ℃ and thus increases the amount of cristobalite. the increased amount of cristobalite as well as alumina addition led to much more thermal dilation due to their higher coefficients of thermal expansion than that of fused silica. the flexural strengths at room temperature and 1500 ~C were tested, and it was shown that alumina addition could not affect room temperature strength, but decreased the flexural strength at 1500 ℃. In addition, deflection resis- tance during heating to high temperatures was investigated, and the result indicated that alumina addition speeded up high temperature softening of the samples. XRD and scanning electron microscopy.equipped with energy.dispersive spectrometry.（SEMJEDS） analy.is suggested that this softening behavior was related with viscous flow sintering which could be accelerated by.the reaction of alumina and silica with a product of mullite.
