论运动量的安排

针对目前,大多数运动训练中,运动量安排上的不合理的状况,笔者在体操领域中进行了探索。通过对苏联、日本队夺得世界冠军前的训练的有关数据的统计,并结合自己的经验,进行了研究分析,在理论上提出了“训练的适应征象”。并得出了大运动量与成绩密切相关的结论。并且对训练的负荷密度、强度问题做了进一步阐述。     

直升机机场噪声评价方法

现有的机场噪声评价指标主要是针对固定翼飞机设计的,并不能很好地反映军用直升机噪声对机场周围目标的影响。首先分析了军用直升机机场噪声的特殊性,然后研究了现有机场噪声评价指标的内涵和联系,最后采用最大噪声级LAmax和加权等效连续感觉噪声级LWCEPN联合评价的方法对军用直升机机场噪声进行评价。该联合评价方法可以同时反映总噪声级与单次突发噪声的影响,能较为完备地对军用直升机场噪声进行评价。实测案例表明,此方法能更准确有效反映附近居民对噪声影响的感受。     

ATS资源选择与配置的灰色局势决策模型

ATS研制的日益复杂精细化趋势使得测试资源的优化选择和配置问题也日益突出。针对传统方法存在不足,基于灰色理论和多目标多属性决策理论提出了一种快速、有效的资源选型决策方法:首先综合分析资源选择与配置的重要因素及测试属性,构建了灰色局势资源决策模型;然后通过对多个配置目标加权合成求解该模型,并利用属性权重进行二次决策,最后获得最优的资源选择与配置方案。工程实例分析表明,该方法科学可靠、可操作性强,能够有效解决ATS硬件集成中的测试资源选择与配置问题。     

Progress in magnetic couple system of nitroxidemetal complexes

Metal_radical method is an effective approach to synthesizing magnetic molecular materials. With the development in decades, the study of nitroxide_metal complexes has made great progress in model, theoretical treatment and design of molecules. Several mechanisms of the metal_radical magnetic coupling are discussed. Molecular magnetic project of nitroxide_metal complexes has made fruitful achievements, but crystal magnetic project is difficult to be controlled, and it is a challenge to chemists. The studies on nitronyl nitroxide_metal complexes are summarized. At present, there are three major approaches to increasing the T c of the metal_radical compounds: (ⅰ) Searching for nitronyl nitroxide ligands that can yield 3_D ferro_ or ferrimagnetic structures; (ⅱ) decorating the structure of radicals with the aim to enhance the coordinate capability of radicals; (ⅲ) grafting polynitroxide radicals as a versatile bridge. The third approach, namely searching for polynitroxide ligand, will serve as a hopeful strategy for exploring higher T c radical molecule_based magnets.     

Microstructure and optical properties of Ag5In5Te47Sb33 phase change thin films with high reflection in thermal annealing process

The microstructure and optical properties of Ag-5In-5Te 47Sb 33 phase change films with high reflection in the thermal annealing process were systematically reported. The as_deposited film is amorphous and its crystalline temperature is 160℃. The annealed films are crystalline. The crystalline phases are AgInTe-2, AgSbTe-2 and Sb when annealed at low temperature. When annealed at 220℃, the AgInTe-2 phase disappears and the amount of AgSbTe-2 is the largest. The research of electronic transmission microscopy shows that the morphology of AgSbTe 2 is sphere and that of Sb is bludgeon. The reflection of the annealed films is higher and reaches its peak value at 220℃.
