摘要：为了研究高性能磁编码器角度解算芯片优化设计的相关问题,建立了采用数字坐标旋转机(CORDIC)算法和数字Ⅱ型系统实现的全数字跟踪型角度解算芯片的误差模型,在此基础上推导出CORDIC数字算法和Ⅱ型系统的误差表达式,然后根据此表达式对芯片内部的运算字长进行优化,最后采用VerilogHDL硬件描述语言建立了全数字角度解算芯片的验证系统。仿真和实验结果验证了芯片误差模型的正确性以及优化设计的可行性,当采用12Bits的A/D转换器时,其解算精度可以达到±0.042°。

摘要：Unlike the previous research works analyzing the stability of the T-S （Takagi-Sugeno） fuzzy model, an extension on the stability condition of T-S fuzzy systems with a different strategy is provided. In the strategy a new variable, which is relative to the grade of fuzzy membership function, is introduced to the stability analysis and a new stability conclusion is deduced. The definition of stability condition in this paper is different from previous works, though they are similar in form. With the proposed method, the simulation in flight control law shows a better effectiveness.

摘要：目的比较三种低分子量肝素(依诺肝素、那屈肝素和达肝素)在急性冠脉综合症(ACS)介入治疗中的安全性和有效性。方法本研究采用前瞻性、随机、单盲、单中心设计,76例入选的ACS患者随机分为依诺肝素组(1mg/kg)、那屈肝素组(0.01ml/kg)和达肝素组(120IU/kg),每12h皮下注射一次,至少使用48h后行冠状动脉造影或经皮冠状动脉介入术(PCI),所有手术在末次注射低分子量肝素(LMWH)后8h以内完成,术中不追加LMWH或普通肝素(UFH),监测三组手术前和手术结束时的部分活化凝血酶原激酶时间(APTT)和抗Xa因子活性,同时观察30d终点事件包括死亡、急性心肌梗死、急性左心衰和靶血管再次重建和严重出血事件。结果三组病例手术前和手术结束时平均APTT差异无统计学意义,术前和手术结束时APTT≥45s的病例数在依诺肝素组、那屈肝素组和达肝素组分别为24例(96.0%)、23例(95.8%)和26例(96.3%),差异无统计学意义。三组手术前和手术结束时抗Xa因子差异无统计学意义,但达到抗Xa因子≥0.5IU/L的比例不同,在依诺肝素组、那屈肝素组和达肝素组分别为:术前23例(92.0%)、21例(87.5%)和17例(63.0%)(P=0.018),手术结束时22例(88 0%)、19例(79.2%)和15例(55.6%)(P=0.022)。30d随访三组终点事件的发生率差异无统计学意义,未发生严重出血事件发生。依诺肝素组发生1例因急性左心衰导致死亡,1例术后血小板<10×10^(12)/L,另有1例输血200ml;那屈肝素组发生1例靶血管再次重建;达肝素组1例术中支架后急性血栓形成,导致急性前间壁心肌梗死。结论依诺肝素、那屈肝素和达肝素在ACS患者心导管室应用中均安全有效,术前皮下注射LMWH 4次且手术在末次注射的8h内完成,不需在冠状动脉造影和介入手术中静脉追加LMWH或UFH。

摘要：光学薛定谔猫态不仅是量子力学基本问题的主要研究对象之一,也是连续变量量子信息的重要资源.在其实验制备中,对触发光路进行滤波操作是决定猫态的纯度、产率等重要参数的关键环节.本文介绍实验中的滤波设计以及滤波腔腔长的测量方法.依据设计要求,腔长lFC应满足条件189μm>lFC>119μm,如此短的腔长用常规方法难以较准确地测量.利用高阶横模的古依相移测得腔长为141μm,满足设计要求.该测量方法不依赖于腔内任何介质的色散等特性,具有一定的普遍性.
