试论卡尔纳普的真理标准

卡尔纳普主张从哲学中清除形而上学。他拒斥行而上学．对综合命题提出了确证代替证实的标准,后来走向概率研究,为现代归纳逻辑发展开辟了新方向;对于分析命题则从句法分析到语义分析,为语言哲学和分析哲学作出了贡献。然而他主张的物理主义却并未成为现实。     

重庆上市公司互保圈现象的会计思考

在市场经济环境下，贷款担保作为上市公司融通资金的一种方式，是企业的一种正常的经营行为。它可以减少交易风险、促进资本市场发展。然而，目前由于种种原因，上市公司互保不仅没有起到化解市场风险的作用，反而加大了证券市场和金融市场的风险，严重扰乱了资本市场的正常运行。因此，本文拟通过思考重庆“互保圈”现象，分析“互保圈”形成的原因及危害，并由此提出相应的对策与建议。     

不同生境冷蒿花期激素动态及对成花的影响

以典型草原与荒漠草原冷蒿植株为供试材料,在花期内测定不同居群冷蒿营养枝、生殖枝内源激素吲哚乙酸(IAA)、赤霉素(GA3)、脱落酸(ABA)含量的动态变化。结果表明:在花期发育过程锡林浩特市与鄂托克旗冷蒿中IAA、A9.BA、GA3含量变化均差异显著。其中三者的浓度关系为:GA3>IAA>ABA。两试验区进入花期内源ABA浓度都呈上升趋势,可以确定其对冷蒿而言是促进成花的激素。IAA与GA3进入花期总体呈下降的趋势,表明二者对于成花具有抑制作用。内源激素比例分析表明,两试验区ABA/IAA和ABA/GA3比值进入花期呈上升的趋势,到盛开期达到顶峰,之后迅速降低,反映出激素的平衡对于其成花亦起着重要的调控作用。     

党的先进性建设如何借鉴国际共产主义运动的基本经验教训

前苏联及东欧共产党丧失执政地位使国际共产主义运动遭受重大挫折的原因有很多，最重要的因素是苏东共产党蜕化变质。没有按照党的先进性来建设党，丧失了党的思想、理论、阶级基础、群众基础、前进方向的先进性，从而失去了它作为无产阶级先锋队的作用，削弱乃至丧失了执政能力，最终葬送了社会主义事业也葬送了党的自身。国际共产主义的经验教训对中国共产党人在全党开展先进性建设的启示是深刻而巨大的：在新的形势下必须坚持党在指导思想上与时俱进；必须从严治党，建立党的先进性建设长效机制；必须加强党的执政能力建设。巩固党的执政基础；必须加大反腐败力度。永葆党的先进性。

Analysis of Spectral Characteristics Based on Optical Remote Sensing and SAR Image Fusion

Because of cloudy and rainy weather in south China, optical remote sens-ing images often can＇t be obtained easily. With the regional trial results in Baoying, Jiangsu province, this paper explored the fusion model and effect of ENVISAT/SAR and HJ-1A satel ite multispectral remote sensing images. Based on the ARSIS strat-egy, using the wavelet transform and the Interaction between the Band Structure Model （IBSM）, the research progressed the ENVISAT satel ite SAR and the HJ-1A satel ite CCD images wavelet decomposition, and low/high frequency coefficient re-construction, and obtained the fusion images through the inverse wavelet transform. In the light of low and high-frequency images have different characteristics in differ-ent areas, different fusion rules which can enhance the integration process of self-adaptive were taken, with comparisons with the PCA transformation, IHS transfor-mation and other traditional methods by subjective and the corresponding quantita-tive evaluation. Furthermore, the research extracted the bands and NDVI values around the fusion with GPS samples, analyzed and explained the fusion effect. The results showed that the spectral distortion of wavelet fusion, IHS transform, PCA transform images was 0.101 6, 0.326 1 and 1.277 2, respectively and entropy was 14.701 5, 11.899 3 and 13.229 3, respectively, the wavelet fusion is the highest. The method of wavelet maintained good spectral capability, and visual effects while improved the spatial resolution, the information interpretation effect was much better than other two methods.     

Hg2+胁迫对小麦幼苗POD、CAT和SOD同工酶的影响（英文）

[Objective] This work was aimed to explore the mechanism of Hg2+ toxicity on plants.[Method]Activities of peroxidase(POD),catalase(CAT)and superoxide dismutase(SOD)were investigated in wheat(Triticum aestivum L.)seedlings under Hg2+ stress at different concentrations.[Result]① There were no obvious effects on the growth of seedlings when the concentration of Hg2+ was lower than 0.10 mmol/L.However,toxic effects on the growth of seedling were observed when the concentration of Hg2+ was higher than 0.10 mmol/L.② Different tissues showed different resistant ability in response to Hg2+ stress.The leaves and roots of wheat seedlings were more insensitive to Hg2+ toxicity.③ CAT was more sensitive to Hg2+ stress compared to POD and SOD.[Conclusion]The toxic effect was related to the concentration of Hg2+(0.10 mmol/L).The higher concentration of Hg2+ could affect the expression of POD,CAT,and SOD isozymes in the leaves,roots of wheat seedlings and germinated seeds,which further affect the normal metabolism of membrane lipid and inhibit the growth of wheat seedlings at last.
