We first state general linear model, ridge-type estimator and general ridge-type estimator, and the constraint biased estimator. And then, we introduce some basic theory about matrix and some conclusion about the admissibility of estimator in Gauss-Markov model. In the third chapter, we discussion several equivalent characterization of the best linear unbiased estimation, we proved that admissible characterization of admissible of linear estimation is as conditional general ridge-type estimation in general linear model. A necessary and sufficient condition that homogeneous linear estimator is admissible estimator is obtained.

On the basis of referring to preceding relevant achievements and exploring the entirestate of the occurrence and development of the RMA,the dissertation focuses on theRMA's origin,essence and mechanism.Then,it draws some conclusions:(1)Far fromoccasionally,the RMA has specific interior factors and external conditions.As a resultof the demand for international political and military struggle and the advancement inscience and technology,the RMA conforms to the trend of the times.(2)As far as itsessence is concerned,the RMA is such a process,during which all countries reformmilitary system wholly in order to realize its informatization,integration andintelligentization after information and knowledge have become dominant factors ofmilitary strength owing to extensive application of high technology around informationtechnology in the military field.(3)During the extensive and thorough reformation in thewhole world,all factors vary sooner or later and affect one another,and promote theevolution of the military system to make the transition from mechanized form tointelligentized one.

论文充分借鉴、吸收前人的有关研究成果，在分析、考察世界新军事革命发生、发展的总体状况的基础上，由具体到抽象，重点探讨了新军事革命的发生动因、本质特征和运行机制，认为：新军事革命的发生与发展不是偶然的，而有其特定的内在动因和外部条件，它既是时代发展变化的客观要求，也是国际政治军事斗争需要与科学技术进步共同推动的结果；这场军事革命的实质，是在以信息技术为核心的高新技术广泛应用于军事领域，信息与知识日益成为军事力量的主导性要素的新条件下，世界各国根据系统原则对军事领域进行变革，努力促使整个军事系统实现信息化、知识化、一体化，进而形成全新的智能化军事形态的过程；新军事革命具体表现为广泛而深入的军事改革，在其发生与发展的过程中，军事诸要素先后变革并相互影响、相互作用，推动整个军事系统不断演进，逐步实现机械化军事形态向智能化军事形态的过渡，最终确立全新的智能化军事形态。

The impacts of printing process and curing condition on antenna resistance are shown as follows: higher resistance of a printing antenna is generated not only by higher print pressure and velocity, which result in inadequate ink transfer, but also by lower curing temperature and shorter curing time, which can result in imperfect combustion of organic vehicles in silver ink.

印刷工艺与固化条件对天线电阻的影响主要表现在：较高的印刷速度与印刷压力会使银浆转移不充分，并导致天线电阻增加；而较低的固化温度、较短的固化时间也会使银浆中的有机载体不能充分燃烧，从而增加天线电阻。
