秦汉太子六百石以下属官考

秦汉时期为太子设官建职，藩卫储君，成为我国封建社会的一项基本政治制度。太子不但拥有一大批类似皇帝少府、皇后后官官员组成的负责管理、照料其日常生活的侍从、服务人员、而且还拥有众多的负责掌管表奏、进谏、谋议的文书、参谋人员。这就为其日后登基继统，行使统治国家的权力，奠定了坚实的基础。     

井姿态参数的工程算法设计

利用3维加速度计和3维磁通门的数据来计算测井或钻井时的井斜角、井斜方位角和仪器方位角等井的姿态参数已经相继在地层倾角测井仪、高精度连续测斜仪和随钻测量系统中得到了应用。本文从工程实现和实时处理的角度提出的一种算法具有运算速度快和精度较高的特点。实现该算法的设奋已装配到有关仪器上开始为油田服务。     

A Cambrian micro-lobopodian and the evolution of arthropod locomotion and reproduction

The evolutionary success of arthropods, the most abundant and diverse animal group, is mainly based on their segmented body and jointed appendages, features that had evolved most likely already before the Cambrian. The first arthropod-like animals, the lobopodians from the Early Cambrian, were unsclerotized and worm-like, and they had unjointed tubular legs. Here we describe the first three-dimensionally preserved Cambrian lobopodian. The material presented of Orstenotubulus evamuellerae gen. et sp. nov. is the smallest and youngest of a lobopodian known. O. evamuellerae shows strikingly detailed similarities to Recent tardigrades and/or onychophorans in its cellular-structured cuticle and the telescopic spines. It also shows similarities to other, longer known lobopodians, but which are ten times as large as the new form. These similarities include the finely annulated body and legs, which is characteristic also for Recent onychophorans, and paired humps continuing into spines situated dorsally to the leg insertions, a feature lacking in the extant forms. The morphology of O. evamuellerae not only elucidates our knowledge about lobopodians, but also aids in a clearer picture of the early evolution of arthropods. An example is the single ventral gonopore between a limb pair of O. evamuellerae, which indicates that a single gonopore, as developed in onychophorans, tardigrades, pentastomids, myriapods and insects, might represent the plesiomorphic state for Arthropoda, while the paired state in chelicerates and crustaceans was convergently achieved. Concerning life habits, the lateral orientation of the limbs and their anchoring spines of the new lobopodian imply that early arthropods were crawlers rather than walkers.

星虫动物门系统发生研究进展

根据已经发表的研究资料,总结星虫的一般生物学特点,回顾星虫动物门形成的过程及星虫动物门系统进化研究的历史和现状。星虫以其独有的特点被提升到门的位置,已经广泛为人们所接受,但是对于星虫的分类和系统进化上的亲缘关系一直没有形成一致的意见。在星虫的分类学上,大多数学者认同Cutler和Gibbs的分类系统,即将星虫分成2个纲、4个目、6个科和17个属,但是星虫在系统进化上的亲缘关系的研究结果不一致。原因可能在于分析方法上的不同,建议进行各种数据的联合分析,并以较为合理的方式解决分析中的和谐性问题,统一地确定出星虫的亲缘关系。     

剔除异部雷达信号方法的研究与应用

密集信号环境下，被动雷达导引头信号处理系统中，由信号跟踪器给出的预测宽波门中难免会有异部雷达信号．文中提出利用相位差和载频等参数，剔除宽波门内可能存在的异部信号的方法，完善了对目标信号的选择与跟踪；以高速DSP＋FPGA为计算核心构成硬件平台，实时地给出跟踪窄波门，提高了系统跟踪精度；采用AD8302幅相测量芯片，极大地简化了系统计算量．在实际应用中取得了很好的效果．
