逻辑差概念在表征基于逻辑的知识库中起到重要作用,这些知识库持续受到动态变化的影响,它们之间存在实质性差异。这一概念与遗忘密切相关,它在各种逻辑中得到了广泛探讨。针对命题理论的相关符号,提出了3种差概念——逻辑差异、子句差异和素子句差异,以分别捕获逻辑推理、子句推理和素子句推理的差异;研究了它们的性质和计算复杂性。结果表明,涉及逻辑差的各种决策问题在多项式层次结构中比相应的可满足性问题高一个层次,除了2-CNF理论,其相关决策问题是易处理的。随机3-CNF、2-CNF和Horn理论的大量实验结果揭示了子句差和素子句差的一些有趣现象:在随机3-CNF理论和2-CNF理论中,子句和素子句差的子句数量都表现出与它们的可满足性类似的相变特征。然而,在随机Horn理论中,尽管子句差的子句数量表现出与其可满足性类似的相变,但素子句差的子句数量与子句差情形十分不同,这些结果揭示了随机命题知识库演化中其可满足性相变现象的新特征:在相变阈值附近的知识库演变会产生更多的差异。

AIM： To examine the expression of high mobility group box-1（HMGB-1） and intercellular adhesion molecule-1（ICAM-1） in the retina and the hippocampal tissues; and further to evaluate the association of these two molecules with the alterations of blood-retinal barrier（BRB） and blood-brain barrier（BBB） in a rat model of type 2 ***： The type-2 diabetes mellitus（DM） model was established with a high-fat and high-glucose diet combined with streptozotocin（STZ）. Sixteen weeks after DM induction, morphological changes of retina and hippocampus were observed with hematoxylin-eosin staining, and alternations of BRB and BBB permeability were measured using Evans blue method. Levels of HMGB-1 and ICAM-1 in retina and hippocampus were detected by Western blot. Serum HMGB-1 levels were determined by enzyme-linked immunosorbent assay（EliSA）.RESULTS： A significantly higher serum fasting blood glucose level in DM rats was observed 2wk after STZ injection（P 〈0.01）. The serum levels of fasting insulin,Insulin resistance homeostatic model assessment（IRHOMA）,total cholesterol（TC）, total triglycerides（TG） and low density lipoprotein cholesterol（LDL-C） in the DM rats significantly higher than those in the controls（all P 〈0.01）.HMGB-1（0.96±0.03, P 〈0.01） and ICAM-1（0.76±0.12, P 〈0.05） levels in the retina in the DM rats were significantly higher than those in the controls. HMGB-1（0.83±0.13, P 〈0.01） and ICAM-1（1.15 ±0.08, P 〈0.01） levels in the hippocampal tissues in the DM rats were alsosignificantly higher than those in the controls. Sixteen weeks after induction of DM, the BRB permeability to albumin-bound Evans blue dye in the DM rats was significantly higher than that in the controls（P 〈0.01）.However, there was no difference of BBB permeability between the DM rats and controls. When compared to the controls, hematoxylin and eosin staining showed obvious irregularities in the DM ***： BRB permeability increases significantly in rats with type-2 DM, which may be as

为了探明地膜覆盖条件下谷子产量效应的主要影响因素及其影响程度,采用整合分析法比较分析了地膜类型、田间管理措施和自然条件对谷子增产效应的影响。结果表明:与不覆膜相比,覆膜条件下谷子的平均增产率为35.5%(95%CI 26.5%~34.2%);覆盖不同类型地膜对谷子产量的提高幅度由大到小依次为渗水地膜(65.30%)>聚乙烯地膜(白色:36.62%;黑色:23.62%)>降解地膜(18.24%);在自然条件方面,地膜覆盖对西北地区谷子产量的提升幅度最显著,达到了61.20%,随后是西南地区和华北地区,分别提升了23.43%和17.87%,而华东地区的提升幅度最小,仅为10.97%;1997—2004、2017—2022年这两个时期覆膜后谷子增产率较高,分别为51.81%和42.48%;在年降水量12℃时,覆膜种植谷子的增产效果最好;在田间管理措施方面,当施氮量≤85 kg/hm^(2)、施磷量2)或施钾量≤45 kg/hm^(2)时,谷子覆膜后的增产影响更显著;当种植密度30万苗/hm^(2)时谷子增产率比种植密度≥30万苗/hm^(2)时高16.47个百分点;黑垆土田地上覆膜种植谷子的增产率最高。因此,提高谷子覆膜增产效应,需要综合考虑地膜类型、田间管理措施以及当地的自然条件等因素。
