随着CaO加入量的增加(15wt％以内),我国水铝石-高岭石类型(DK型)烧结高铝矾土的物相组成和显微结构的变化以及相应的高温力学性能的变化按以下两个阶段进行:第一阶段,由于莫来石量锐减以及钙长石和玻璃相含量明显增多,莫来石的网络结构和刚玉颗粒的直接结合都逐渐被破坏,结果导致高温机械性能下降;第二阶段,由于六铝酸钙网络的形成和增长,而低熔物相含量基本不变,1200℃以下的高温力学性能稍有改善。本试验范围内,第一阶段到第二阶段的转折点:对于Ⅰ等材料,CaO的加入量为6wt％;对于Ⅱ等材料,CaO的加入量为10wt％。认为当结晶相由高熔和低熔两种晶相组成时,材料的高温力学性能取决于低熔物相效应(钙长石、玻璃相等)和高熔晶相效应(刚玉、莫来石、六铝酸钙等)。

This paper investigates the free vibration and transient response of interconnected structures including double curved beams and intermediate straight beams,which are all constructed from functionally graded porous(FGP) materials. The strain potential and kinetic energies of each beam along with the work done by the external force are calculated. Additionally, a higher-order beam element is introduced to derive stiffness and mass matrices, along with the force vector. The curved and straight beams are discretized, and their assembled stiffness, mass matrices, and force vectors, are *** conditions at the joints are used to derive the total matrices of the entire structure. subsequently, the natural frequencies and transient response of the system are determined. The accuracy of the mathematical model and the self-developed computer program is validated through the comparison of the obtained results with those of the existing literature and commercial software ANsYs, demonstrating excellent ***, a comprehensive study is conducted to investigate the effects of various parameters on the free vibration and transient response of the considered structure.

We discuss one-dimensional Dirac oscillator, by using the concept doubly special relativity. We calculate the energy spectrum by using the concept doubly special relativity. Then, we derive another representation that the coordinate operator remains unchanged at the high energy while the momentum operator is deformed at the high energy so that it may be bounded from the above. Actually, we study the Dirac oscillator by using of the generalized uncertainty principle version and the concept doubly special relativity.

The ultra fine (solids (Bs) were separated from bitumen which was washed by toluene and centrifugated at 2000 rpm. The result of PAs FTIR and image of TEM showed that the structure of Bs particles was smiliar to that of kaolinite clay. On the surface of Bs, both toluene insoluble organic matter and structural Oh group are detected at the same time. The surface characteristics imparted a bi-wettable nature to the Bs. As a result, the Bs is able to stabilize fine water emulsion in the bitumen phase. The organic matter associated with Bs is a possible factor of the fouling on catalyst and equipment.

The fuzzy production scheduling problem considering mould maintenance(FPsP-MM) is studied. The processing time and the maintenance time are represented by triangular fuzzy numbers. When tasks are executed based on the sequence provided by the fuzzy schedule, the real duration of each task needs to be known so the posteriori solution with deterministic processing times can be obtained. Therefore, the concept of the schedule robustness needs to be considered for the fuzzy problem. The robustness is considered as the optimization objective except for the fuzzy makespan in this research. To optimize these two objective functions, a multi-objective pigeon inspired optimization(MOPIO) algorithm is developed. To extend the pigeon inspired optimization(PIO) algorithm from the single-objective case to the multi-objective case, nondominated solutions are used as candidates for the leader pigeon designation and a special crowding distance is used to ensure a good distribution of solutions in both the objective space and the corresponding decision space. Furthermore, an index-based ring topology is used to manage the convergence speed. Numerical experiments on a variety of simulated scenarios show the excellent efficiency and effectiveness of the proposed MOPIO algorithm by comparing it with other algorithms.
