研究机动目标在射击门下的同一性分布可为火控理论中命中概率研究与应用提供一普适性的理论依据。分析了具有随机因素的机动目标在穿越射击门时的随机计数特征,给出了齐次泊松分布的推断,对具有二维独立自相关正态随机目标在矩形域和椭圆域下待机时间和滞留时间的概率密度估计及其误差进行了仿真研究,得到其密度估计模型及其误差为伽玛分布的补偿修正估计模型。     

胚胎早期中脑和后脑发育的基因调控新机制

在动物的早期胚胎发育中,最初的神经系统就像一根“管子”贯穿于胚胎的背部,从头到尾几乎一样粗细,被称为神经管。随着发育的推进,“管子”的前部逐渐膨大,分化成3个脑泡——前脑、中脑和后脑,并最终发育成脑;后部则越来越细,发育成了脊髓。在人脑的发育过程中,随后还有一系列复杂的分化过程。首先是前脑继续分化为两部分——端脑和间脑,前者后又发展成两个大脑半球,而后者则发展成为丘脑、下丘脑和松果体;胚胎的中脑生长较慢,基本保持了原来的“管状”形态;后脑分化为脑桥、小脑及延髓。控制中脑和后脑发育的关键区域位于中脑与后脑之间的…     

从宗教文化透视美国高等教育捐赠传统

慈善捐赠在美国高等教育发展进程中具有十分重要的意义，它支撑了美国的近代高等教育，拓展了美国高校的服务职能，加速了美国研究型大学的诞生。从文化心理思考，美国的高等教育捐赠植根于美国浓厚的宗教文明，导致了美国近代高等教育的诞生和现代美国高等教育的高度发达。

Physical location of terminal markers belonging to five linkage groups in maize RFLP map using in situ hybridization

Ten terminal or subterminal RFLP markers belonging to linkage groups 1, 3, 5, 6, and 10 in maize RFLP map were physically locted onto maize mitotic chromosomes with in situ hybridization. All biotinylated probes from 600 to 2 250 bp were detected by DAB staining. The markers belonging to linkage groups 1, 3, 5, 6, and 10 correspondingly located at the chromosomes 1, 3, 5, 6, and 10. All of the tested markers except bnl6.25 and umc44 were duplicated sequences. Each of them was also labeled on another chromosome besides on the chromosome corresponding to its linkage group. The marker bnl3. 04 was triplicated sequences and the signals were detected on three nonhomologous chromosomes. In the tested ten markers, there were only four located at the ends of corresponding chromosomes. Others were located at sites midway along the chromosome arms or near the centromeres. The region covered by two terminal or subterminal markers in each of linkage groups 1, 3, 5, and 6 occupied 80.02%, 38.25%, 82.30% and 51.16% of the region of both short and long arms in chromosomes 1, 3, 5, and 6 respectively. Only two terminal markers of linkage group 10 covered the whole chromosome 10. In some linkage groups, two terminal or subterminal markers covered a short genetic distance but were physically distant, while two covering a longer genetic distance were physically closer.

从曲谱看《全元散曲》存在的若干校勘问题

隋树森编的《全元散曲》作为散曲研究的材料很完备,但在使用过程中发现其中仍有诸如断句、脱韵、字词讹误、次序颠倒等等不少疏失之处,试依据曲律、曲韵对其中的字句脱漏、讹误、颠倒及其他一些讹误进行校勘,以期为研究者提供些参考。     

机器发现引发的创造观之争——简评H．西蒙与M．西克森特米哈伊的争论

机器发现作为一种新的研究方法,获取了其他创造力研究方法无法获取的创造性思维过程的精确证据,但同时遭到了创造力系统观持有者的质疑.双方观点的代表学者H.西蒙与M.西克森特米哈伊就此展开了一场创造力研究史上不可忽略的争论.争论的焦点在于:创造力是问题解决还是问题发现?计算机能否复制人的创造性过程?争论的实质在于这两种创造力研究新视角在创造观上的分歧.这场争论弓j发了学界对创造力本质的深入探讨,同时也给创造力研究带来了方法论上的启示.
