The 196 PSVT cases (97%, 196/202) immediately stop by overdrive suppression or program prestimulation.

对其202例PSVT患者均采用短阵快速刺激或程序期前刺激，PSVT即刻终止的有196例，转复成功率97%。

The PSVT patients diagnosis by emergency also received overdrive suppression or program prestimulation.

另外对54例急诊PSVT患者直接予以短阵快速刺激或程序期前刺激终止之。

Methods: The transesophageal atrial pacing and electrophysiologic study were performed in 237 patients with history of tachycardia, if PSVT was induced, the patients received overdrive suppression or program prestimulation.

选择237例有心动过速发作史的患者进行食管心房调搏检查，如果诱发出阵发性室上速，进行12导联心电图记录后，予以短阵快速刺激或程序期前刺激终止之。

A cross shaped sum-difference network is constituted by microstrip ramose coupler with compact structure and calculated by ADS,while the 8×8 rectangular patchs,which is optimized by HFSS on basis of the method of parameter load and so on,form the transmiting/receiving antenna.

使用ADS优化设计了一种结构紧凑的&十&字形和差网络，并且使用参数加载等方法，在HFSS中仿真出一个8×8的微带矩形贴片天线阵列作为收/发天线，和差网络和微带天线阵列组成单脉冲天线阵。8×8天线阵列、和差网络和馈电系统在同一平面上，所以此天线阵列与传统单脉冲阵列相比体积更小，结构更紧凑，对该天线阵列进行了研制和测试，测试结果符合设计要求。

Our main result is for any immigration-emigration birth and death matrix random environment, q, with birth rateless than death rate, there are a unique q-process in random environment P9*(0;t and a bi-immigration birth and death process in random environment with random transition matrix P(9*{Q);t such that P9*(0;t is ergodic and X* is a strictly stationary process.

在这一部分，我们将经典的生灭过程理论推广到了随机环境下，证明了对任意给定随机环境移入-移出-生灭密度矩阵q，当生率小于死率时，存在一个唯一的随机环境下的q过程—θ~*(0；t和随机环境下的移入-移出-生灭过程，使得严平稳，遍历，其随机转移阵为？

Through transposition and transmission of reachability ,it is used to eliminate unknown relations using of reachability and reachless relations from initial matrix and using of interactive method.

这种方法从初始可达阵开始，利用可达关系的传递性，经过一系列的变换，消除一部分未知关系，再利用不可达关系，进一步消除一部分未知关系，最后采用人机交互的办法消除剩余的未知关系，从而得到利用可达矩阵表示的系统结构模型。

These three algorithms can avoid to recompute the nth order head submatrix of the Jacobi matrix. Moreover, the last two algorithms are more stable, their precision can match well with the algorithm of Boley and Golub.

这三种算法都可以避免重构Jacobi矩阵的n阶首主子阵，并且后两种算法更稳定，数值精度可以(来源：A1cBC论c4文网www.abclunwen.com)与Boley和Golub的算法媲美。

Chapter 2 discusses the function of optimum array based on the minimum meansquared error principle in CDMA system, the method of produce the reference signal, and proved whether the reference signal is the correspond PN code sequence or respread signal, the result of the array's weight converge can converge the same optimum weight under the condition that the PN sequence in a bit of data is long enough. In this chapter, we finally get the beam pattern and the correlate bit error rate after converge when several CDMA signal arrives in different direction.

本文的主要贡献及创新之处是：首次从理论上探讨了基于最小均方误差准则的最优天线阵在CDMA系统中的多址干扰抑制性能及其参考信号的产生方法，证明了采用有用信号相应的扩频码作为参考信号与采用将解扩信息与扩频码进行重扩频后的信号作为参考信号来调节自适应天线的权值均可使权值收敛于同一最优解。
