马克思的"人的全面发展"思想与素质教育

马克思的"人的全面发展"思想是素质教育的理论根据。按照素质教育的要求,高等教育必须转变以往重专业知识、轻综合素质的人才培养模式,在提高学生的整体素质基础上,注重学生潜力的开发、个性的发展和创新精神的培养。     

Helmholtz potentiality conditions for systems of difference-differential equations

For operators corresponding to systems ofμth-order difference-differential equations of neutral type, necessary and sufficient conditions for potentiality with respect to the classical bilinear form are obtained. These results are applied to first-order quasilinear systems. Translated fromMatematicheskie Zametki, Vol. 64, No. 3, pp. 437–442, September, 1998. The author wishes to express his thanks to V. M. Savchin for fruitful discussions and useful remarks.     

基于辐射力模型的广西城市辐射范围研究

基于辐射力模型对广西城市辐射范围进行研究,发现：广西绝大部分城市规模小,辐射范围小;城市之间相互作用、相互影响弱;湘桂-南防铁路沿线地区最有可能形成城镇密集带.     

宝鸡市土地生产潜力分析

土地生产潜力表明人们对资源利用的可能程度，反映一个地区生产所能达到的最大水平，本文根据宝市自然、社会经济的统计数据，通过一系列模型的测算，得出宝鸡市土地水平潜力，即耕地单产粮食为生亩５４４公斤，复种指１．７０。在此基础上，利用宝鸡市粮食产和复种指数的时间序列数据，依据数学模型和专家系统，预测出宝鸡市在公元２０００年和２０１０年的土地实际生产水平，它们分别是２０００年，２６７公斤／亩，１．２１；２０

On the Physical Reality of Quantum Waves

The main interpretations of the quantum-mechanical wave function are presented emphasizing how they can be divided into two ensembles: The ones that deny and the other ones that attribute a form of reality to quantum waves. It is also shown why these waves cannot be classical and must be submitted to the restriction of the complementarity principle. Applying the concept of smooth complementarity, it is shown that there can be no reason to attribute reality only to the events and not to the wave or to the initial state of a given system. Thereafter, an experiment proposed by the authors is presented, where it is shown that the wave-like behaviour allows predictions that are not allowed on the grounds of a particle-like behaviour. In conclusion, we upheld that quantum waves must be real even if they do not belong to the same ontological level of events, which connected with particle detections.Institute of Philosophy, University of Urbino, Urbino 610 29, Italy; tarizzi@uniurb.it     

对我国发行地方政府债券的思考

我国《预算法》明确规定地方政府不能发行债券进行公用事业建设项目的融资,但是随着经济发展和改革深入,当时制定法律所考虑的因素已发生了变化,我们应该重新审视地方政府债券发行条件,对是否允许发行地方政府债券作出判断,并作出决策,以顺应改革及经济发展的需要。

Studies on the utilization potentiality of the nucleo-cytoplasmic hybrid in wheat

A series of comparative studies was carried out on the genetic effects of 25 alien cytoplasms of wheat on the growth potential, heading stage, fertility, resistance against diseases, important agronomic traits and its heterosis of 125 nuclei-cytoplasmic hybrids of wheat. The results indicated that there were clearly effects of alien cytoplasms on some characteristics, but the nucleus still exerted main effect on other characteristics. The effect of interactions between nucleus and cytoplasm was comparative obvious in some combination. Consequently, when we utilize the effects of alien cytoplasms, we should pay full attention to the facts such as the characteristic to be improved, the effects of cytoplasm, nucleus, the nucleus-cytoplasm interactions on that characteristics. From the preliminary studies, we believed that the cytoplasmic types of M⁰, S¹, S^v, D², D and B, and the nucleo-cytoplasmic hybrids of (Ae. sharonensis)-B174, (Ae. squarrosa)-352-35 (Ae. cylindrica)-352-35, (Ae. cylindria)-E EN-1, (Ae. cylindrica)-NPFP, and (Ae. speltoides)-352-35 would have some utilization potentiality in cultivar improvement.
