甘肃省2000年干旱气候特征和成因诊断分析

针对甘肃省2000年春季至初夏旱和盛夏前伏旱的持续时间、范围、强度进行了对比分析，干旱持续时间之长、范围之大、为近70年所少见．严重的干旱导致夏、秋粮减产、人畜饮水极度困难．干旱形成的原因是中高纬度大气环流“冬性”较强，副热带高压主体面积偏小、位置偏东且偏北，偏南暖湿气流难以到达甘肃上空．这些结果对防灾减灾措施制定和实施及作为短期气候预测的气候背景都有重要参考意义．     

从谥诔到诔文：论古代诔文体式的形成

诔是汉魏六朝人写作的一种重要的体形式，诔作为一种体形式，形成于两汉之交。以扬雄《元后诔》为代表。诔体形式的形成，是先秦丧祭命谥诔辞与铭颂结合的产物。     

从诸葛菜cDNA文库中筛选过氧化物酶基因

在200mmol／L NaCl诱导下构建诸葛菜苗期的cDNA文库，并从cDNA文库中筛选到一个新的过氧化物酶基因OvRCI，该基因cDNA全长1220bp，包含了一个1128bp的开放阅读框．通过同源分析比较及RT-PCR实验等对该基因进行了分析．结果显示该基因是一个诱导型表达的基因。

A new species of Gobiconodon （Triconodonta, Mammalia） and its implication for the age of Jehol Biota

A new species of Gobiconodon is found from the Yixian Formation of western Liaonlng, China. The new taxa,G zofiae sp. nov., has a confluent opening for branches Ⅱand Ⅲ of the trigeminal nerve on the anterior lamina of the petrosal. G zofiae sp. nov. is similar to Repenomamus in having an ossified Meckel‘s cartilage connecting the lower jaws and ear region. The new species, with enlarged I^1/I1, posteriorly located infraorbital foramen and four mental foramina,distinctly differs from the other species of Gobiconodon. The new material indicates that Gobiconodon has four, not five,upper molariforms. The presence of Gobiconodon in Jchol Biota makes it possible to correlate Jehol Biota with faunas in eastern Asia and North America, and suggests the age of the Yixian Formation to be Early Cretaceous.     

A surface-based DNA algorithm for the minimal vertex cover problem

Abstract DNA computing was proposed for solving a class of intractable computational problems, of which the computing timewill grow exponentially with the problem size. Up to now, many achievements have been made to improve its performance and increase itsreliability. It has been shown many times that the surface-based DNA computing technique has very low error rate, but the technique hasnot been widely used in the DNA computing algorithms design. In this paper, a surface-based DNA computing algorithm for minimal ver-tex cover problem, a problem well-known for its exponential difficulty, is introduced. This work provides further evidence for the abilityof surface-based DNA computing in solving NP-complete problems.
