In this paper, we conduct research on the combat skills training and enhanced mode under the core perspectives of comprehensive physical ascension. In recent years, with rapid development of science and technology and the gradually deep understanding of the life science, people understand the training laws also in development, from the new knowledge and produce a new training theory and method in practice as the old training mode has been breakthrough as development. The theoretical basis of the physical is largely based on the organism biological adaptation for the moving load, the improvement of quality of that any sport is through the various parts of the organism various systems, organs, muscles and even the change of each cell to realize the bit by bit. Our research combines the principles of the comprehensive physical ascension to propose the idea that is meaningful. 展开更多

The lifetime of a lunar satellite orbit is constrained by the non-spherical nature of the Moon’s gravity field. The orbital lifetime of lunar orbits depends significantly on the initial conditions of the orbit. Right ascension of ascending node (Ω) is one of the important orbital parameter affecting the orbital lifetime. In the present work we have analyzed the effect of Ω on the variation of lifetime with altitude for circular lunar orbits. It is found that at a particular initial altitude, a small increase in the altitude results in substantial increase in the orbital lifetime due to effect of the long periodic terms of Earth’s gravity on eccentricity and this transition altitude is different for different Ω. Further, it is observed that the variation of transition altitude with Ω follows a definite, but different trend for orbits with different inclinations. The transition altitude for polar orbits is found to be higher without the effect of Sun and Earth gravity. Variation of transition altitude with orbital inclination is also analyzed. Lifetimes of high altitude circular lunar orbits are analyzed and it is observed that at high altitudes lifetime decreases with altitude. 展开更多

In Confessions,Augustine positively recollects three ascensions that he had experienced ten years earlier.Searching himself in memory,he makes self an object of rational study and thus manifests that he is still influenced by neo-Platonism even after he had been in the Catholic church for a decade.The ascension of self is in the high part of the soul,which fittingly returns to the Intellect and in turn to the One for an ultimate reunion,since the soul descends from the Intellect which emanates from the One.Among the faculties of the soul,Augustine focuses on memory,which is an internal seeing and hearing.In Christianity,the salvation of a sinner comes from the indwelling Holy Spirit.In contrast to the Enneads by Plotinus,this paper analyzes unsolved problems of Augustine,such as saving faith and a distinction between the intelligible world and the spiritual world. 展开更多

Based on the analysis of conditions for airflow reversal within a bypass branch, the airflow reversal phenomena were successfully simulated in the laboratory experiments. Data obtained indicate that airflow reversal within a bypass branch is mainly caused by fire pressure yielded in the combustion branch. In addition, the maximum reversal quantity of airflow occurs in step with the highest temperature of fire, the highest concentration of CO 2 and the lowest concentration of O 2. Moreover, the time that fire size reaches the maximum value corresponds to the time airflow reversal in the bypass branch is most possible. The results are of great significance for guiding rescue work to avoid airflow reversal. 展开更多

By studying an admissible family of branching mechanisms{ψt,t ∈E} introduced in Li [Ann. Probab., 42, 41-79(2014)], we construct a decreasing Levy-CRT-valued process {Tt, t ∈ E} by pruning Lévy trees accordingly such that for each t ∈E, Tt is a ψt-Lévy tree. We also obtain an analogous process {Tt*,t ∈E} by pruning a critical Levy tree conditioned to be infinite. Under a regular condition on the admissible family of branching mechanisms, we show that the law of {Tt,t ∈E} at the ascension time A := inf{t ∈E;Tt is finite} can be represented by{Tt*,t∈E}.The results generalize those studied in Abraham and Delmas [Ann. Probab., 40, 1167-1211(2012)]. 展开更多
