腧穴是脏腑经络之气血输注和聚集于体表的部位。腧穴并非是一成不变的。腧穴的生物物理特性、病理反应性和治疗效应都呈现出动态变化性。腧穴的动态性与气血运行的恒动性、生命活动的节律性、机能状态的反应性密切相关。

采用Un iFed SBR工艺试验装置处理实际生活污水,确定了出水不受进水扰动影响的合适排水比。当将进水/排水时间固定为2 h,排水比不高于41.67%时,可以实现进水与出水的分离,保证良好的出水水质。通过试验分析了Un iFed SBR工艺的除磷脱氮机理在于:进水/排水阶段在反应池底部先后发生了反硝化作用和厌氧释磷反应,后续曝气阶段发生硝化作用和好氧吸磷,因此通过该工艺,可实现同步除磷脱氮。

算法选择对林火蔓延的模拟具有重要作用,既影响模拟的精度与效率,也限制模拟的实用性.对传统的边界插值算法进行优化,并与迷宫算法进行对比分析.研究表明,从耗时方面分析,与边界插值算法(5、7、16 s)相比,迷宫算法在3个时段的耗时(204、458、1 325 s)较长;且随着模拟时间的增加,迷宫算法的耗时呈现倍数增长.从模拟结果的精度上看,边界插值算法虽然模拟结果较为粗糙,但能从整体上反映林火蔓延的趋势,火场覆盖率为59.75%.迷宫算法的模拟蔓延边界细节较为接近实际的蔓延边界,能够反映林火蔓延的详细动态变化,且火场覆盖率达79.51%.

The aim of this study was to uncover ways to mitigate greenhouse gas（GHG） emissions and reduce energy consumption during the composting process. We assessed the effects of different aeration rates（0, 0.18, 0.36, and 0.54 L/（kg dry matter（dm）·min）） and methods（continuous and intermittent） on GHG emissions. Pig feces and corn stalks were mixed at a ratio of 7：1. The composting process lasted for 10 weeks, and the compost was turned approximately every 2 weeks. Results showed that both aeration rate and method significantly affected GHG emissions. Higher aeration rates increased NH3 and N2O losses,but reduced CH4 emissions. The exception is that the CH4 emission of the passive aeration treatment was lower than that of the low aeration rate treatment. Without forced aeration,the CH4 diffusion rates in the center of the piles were very low and part of the CH4 was oxidized in the surface layer. Intermittent aeration reduced NH3 and CH4 losses, but significantly increased N2 O production during the maturing periods. Intermittent aeration increased the nitrification/denitrification alternation and thus enhanced the N2 O production. Forced aeration treatments had higher GHG emission rates than the passive aeration treatment. Forced aeration accelerated the maturing process, but could not improve the quality of the end product. Compared with continuous aeration, intermittent aeration could increase the O2 supply efficiency and reduced the total GHG emission by 17.8%, and this reduction increased to 47.4% when composting was ended after 36 days.

Copper-nickel nanoparticle was directly prepared by flow-levitation method （FL） and sintered by vacuum sintering of powder （VSP） method. Several characterizations, such as transmission electron microscopy （TEM）, scanning electron microscopy （SEM）, X-ray diffraction （XRD）, differential thermal analysis （DTA）, and energy-dispersive X-ray spectroscopy （EDX） were used to investigate the prepared nanostructures. The results of the study show that FL method could prepare high purity Cu-Ni nanocrystals of uniform spheres with size distribution between 20 and 90 nm. After sintering the bulk nanocrystalline copper-nickel has obvious thermal stability and the surface Webster hardness increases with the rising sintering temperature. At the temperature of 900 ℃, the specimen shows higher surface Webster hardness, which is about two times of traditional materials. When the sintering temperature arrives at 1 000 ℃ the relative density of bulk nanocrystals can reach 97.86 percent. In this paper, the variation tendency of porosity, phase and particles size of bulk along with the changing of sintering temperature have been studied.

Excited-states play a crucial role in the optical absorption and luminescence of solids and hence their accurate information is highly desired. Herein, we attempt to seize the excited-states information of Mn^(4+)ions in K_(2)SiF_(6) microcrystals via measuring and calculating their variable-temperature photoluminescence excitation(PLE) spectra. At cryogenic temperatures, an unpredicted splitting of the high-excited-state is observed. Moreover, the two-split high-excited-state levels are further revealed to primarily couple with the two hyperfine split modes of quasi-localized ν2 vibration in the distorted Mn-F_(6) octahedral configuration,whereas the coupling strengths are found to be substantially different from each other. The slightly split vibrational mode is firmly supported by the low-temperature Raman spectra. Jahn-Teller lattice distortion is believed to be responsible for the observed splitting of the electronic high-excited-state and the quasi-localized vibrational mode.
