从国家预决算看民国政府对西藏的财政投入与管理——兼驳“民国西藏独立”论

文章以新发现的中华民国时期国家预算西藏省岁入岁出等报表为依据,结合民国历史档案,分析总结了民国中央政府对西藏的财政投入的种类、数量和性质,同时论述了中央政府对西藏发展金融货币、交通、贸易的支持和管理措施,坚持维护了中央对西藏的主权,从一个侧面批驳了国外敌对势力和藏独集团编造的“民国西藏独立”谬论。     

合理垂直烧结速度的研究

通过考查气流速度的变化研究垂直烧结速度随烧结过程的变化规律。结果表明:垂直烧结速度并非固定不变,而是随着烧结过程的逐步进行发生显著变化;点火保温后,随烧结物理化学反应的进行,燃烧带逐渐形成并变宽且产生过湿现象,导致料层的透气性显著变差,烧结速度显著下降,直至约25 min后过湿层完全消失,透气性变好,烧结速度迅速上升。根据垂直烧结速度变化规律,通过改变负压烧结,进行烧结速度优化实验,结果表明:在保持转鼓强度及成品率基本不变的情况下,将垂直烧结速度由20.08 mm/min提高到21.82 mm/min,利用系数由1.401 t/(m2-h)提高到1.587 t/(m2-h)。     

Perceptual learning of dot pattern

Dot pattern is a type of pattern defined by specific spatial relationship among some dots. As a compensation for concrete and meaningful visual stimuli, meaningless dot pattern can be used as stimuli in learning tasks. We performed an experiment for exploring the perceptual learning process of dot pattern against random-dot background. Participants were required to learn two types of dot patterns (9-dot and 11-dot). They were assigned to two groups: participants in Group 1 learned 9-dot pattern first and 11-dot pattern later, while those in Group 2 learned 11-dot pattern first and 9-dot pattern later. The results showed that participants could acquire the spatial relationship of dot pattern through perceptual learning in relatively short learning time. In comparison with 9-dot pattern, learning time of 11-dot pattern was slightly longer and its accuracy rate lower, but there was significant positive transfer effect from 11-dot pattern learning to 9-dot learning.

A New Discipline of Science-The Study of Open Complex Giant System and Its Methodology

This paper introduces the conception of open complex giant system and the methodology for dealing with the system, with stress on its profound significance in development of science and technology. The authors conclude that the reductionism underlying the exact science is not suitable to open complex giant system, and the only feasible alternative is the meta-synthetic engineering from the qualitative to the quantitative.

Channel Mismatching in Sidelobe Canceler: Limitations and Remedies

After a brief recall of the Sidelobe Canceler (SLC) working principle, including the derivation of a general formula for the Cancellation Ratio (CR), the effects of channel mismatching are investigated. In particular, curves providing CRvalues as a function of amplitude and phase channel mismatching, radar bandwidth, and jammer direction of arrival (JDOA) are provided for the cases of one and two auxiliary antennas. Subsequently, a time -space processor for performance restoration is analyzed in detail. In addition to the above mentioned quantities, the attainable CR value is expressed as a function of the space-time processor parameters. The contribution of the paper is related to the derivation of a number of mathematical equations of CR for several cases of practical interest for the radar engineer. In addition, several curves are presented to assist design of SLC systems.
