贵港航运枢纽船闸引航道回淤试验研究

针对少沙河流上船闸航道泥沙淤问题研究资料甚少的情况,采用物理模型试验方法,研究了贵港枢纽船闸引航道水流泥沙运动规律,分析了引航道淤积的机理及特点,得出了３个特征年份引航道泥沙回淤量及引航道口让区最大淤积厚度,研究表明少沙洒流上的船部引航道淤积仍然是不可忽视的问题,建设中必须考虑相应的清淤措施。     

基于多级分类器的自由手写数字在线识别

设计了一种用于手写字符在线识别的多级分类器模型。在该模型中,通过对四个独立的分类算法进行集成,将脱机方法与联机方法,神经网络方法与传统方法有机地结合起来构成一个完整的手写字符在线识别系统。理论分析和实验结果表明,该集成系统比单一系统具有明显的优越性。

Analysis for the dorsalization potency of the animal blastomeres of the 16 cell stageXenopus embryo

The dorso-ventral axis ofXenopus embryo is established after fertilization. Blastula stage blastomeres acquire different identities as they have inherited different maternal materials which distribute radial symmetrically along the animal vegetal aixs in the full-grown oocyte, and are rearranged by the cortical rotation triggered by fertilization. The vegetal blastmeres demonstrate the different dorsalization potencies in the previous transplantation experiments. The data of blastomere explanting and RT-PCR analyzing indicate that the dorsal ventral bias also exists among the animal blastomeres even during the early blastula stage.     

Discovery of ophiolite in southeast Yunnan, China

The Babu ophiolite in Malipo County, SE Yunnan, consists of three units: ultramafic, mafic and basaltic rocks. Studies of geological mapping, petrology and geochemistry reveal that the gabbro is similar to that in the Troodos ophiolite, and the diabase and basalt belong to a normal MORB-type, analogous to the Shuanggou ophiolite in west Yunnan. The ophiolite studied as a thrust tectonic slab, was overthrust northwards onto the Late Paleozoic-Triassic deep marine deposits of continental margin. It is inferred to be relics of Paleotethyan ocean; namely, a branch of Paleotethys occurs in South China, where the tectonic nature and evolutional history of the area should be reconsidered.     

Genetic diversity of reared N.miichthioides population

The genetic diversity of 30 rearedNibea miichthioides individuals was analyzed by random amplified polymorphic DNA (RAPD) with 20 random primers. The result showed that the genetic diversity of reared individuals was relatively low with 15.31% polymorphism and 0.031 9 of the average difference (AD). The result also indicated that RAPD is a useful way in genetic diversity analysis of fish population.
