一种本体协同冲突的检测方法

针对农业领域分布式的迭代知识协同建构过程中存在的协同冲突及难于检测的问题,提出协同冲突划分、检测与消解方法.把协同冲突与本体一致性问题区别开来,按本体知识编辑操作的影响范围、操作类型及启发式规则把协同冲突划分为硬冲突、软冲突.依据这个划分,给出一个高效的检测算法和冲突消解方案.

晶粒尺寸和热处理对Sm2Fe17N3/Fe3N/BN软磁/硬磁复合材料的合成及磁性能影响

采用高能球磨和真空热处理方法制备Sm2Fe17N3/Fe3N/BN复合材料, 并研究球磨过程中晶粒尺寸变化对固态相变和磁性能的影响.  结果表明: Sm2Fe17N3和Fe3N相产生的条件是Fe的晶粒尺寸达到纳米量级（D＜80 nm）并形成Fe(Sm)固溶体; 随着退火时间的增加, 300 ℃真空退火的球磨样品中Sm2Fe17N3的结晶物增多, 矫顽力提高, 表明样品的磁性能与Sm2Fe17N3的结晶程度有关.

Design of radiation hard phase-locked loop at 2.5 GHz using SOS-CMOS

Abstract: A radiation hard phase-locked loop (PLL) is designed at 2.5 GHz using silicon on sapphire complementary metal-oxide-semiconductor process. Radiation hardness is achieved through improving circuit design without sacrificing real estate. Stability is guaranteed by a fully self-bias architecture. The lock time of PLL is minimized by maximizing the loop bandwidth. Frequency tuning range of voltage controlled oscillator is significantly enhanced by a novel load configuration. In addition, multiple bias stages, asynchronous frequency divider, and silicon on sapphire process jointly make the proposed PLL more radiation hard. Layout of this PLL is simulated by Cadence Spectre RF under both single event effect and total induced dose effect. Simulation results demonstrate excellent stability, lock time < 600 ns, frequency tuning range [1.57 GHz, 3.46 GHz], and jitter < 12 ps. Through comparison with PLLs in literatures, the PLL is especially superior in terms of lock time and frequency tuning range performances.     

The Conflict Between the Traditional Value and Reality In Sister Carrie

Theodore Dreiser relates a story of Carrie 's rise from a poor country girl to a Broadway star in Sister Carrie.An attempt is made in this paper to analyze the cold society.By way of analyzing this unequal and cruel reality to prove:in the world only the fittest can survive,the standards and requirements of morality are challenged and the traditional value is suspected.In the cold reality,any way that can protect oneself or survive in the world is sensible,morality and traditional value are weak and meaning...
