目的:研究妊娠早期正常孕妇、妊娠期糖尿病(GDM)及妊娠期糖耐量异常(GIGT)孕妇性激素结合球蛋白(SHBG)水平与母儿合并症的关系。方法:对正常妊娠组420例和妊娠期糖代谢异常组304例进行50g葡萄糖负荷实验(GCT)检测,其中GCT结果异常者再进行75g葡萄糖耐量实验(OGTT);同时对所有研究对象均进行SHBG的测定并根据其水平高低分组进行母儿合并症的统计。结果:早孕期妊娠合并糖代谢异常孕妇两组血清SHBG值均较正常孕妇者低(P<0.001),而妊娠期糖代谢异常患者的母儿并发症随SHBG水平的降低而增多。结论:SHBG在妊娠期糖代谢异常的早期筛查诊断及母儿预后评估中具有重要意义。

模糊PID控制在伺服系统中的应用

舰船电子对抗 2007年第2期30卷 41-44,50页

作者：史云强船舶重工集团公司723所扬州225001

在现行伺服系统中多采用PID控制方式。传统的PID控制系统虽然具有稳定、结构简单等优点,但是当被控对象参数发生改变或者受非线性因素影响发生变化时不能随之改变,无法满足高性能、高精度的要求。模糊PID控制方式已经在许多领域得到运... 详细信息

在现行伺服系统中多采用PID控制方式。传统的PID控制系统虽然具有稳定、结构简单等优点,但是当被控对象参数发生改变或者受非线性因素影响发生变化时不能随之改变,无法满足高性能、高精度的要求。模糊PID控制方式已经在许多领域得到运用。将模糊PID控制与传统PID控制进行对比,利用模糊推理方法实现了对PID参数的在线自动整定,并且在Matlab软件下,将该控制器在运动控制系统中的应用进行了仿真,结果表明该控制能使系统达到满意的控制效果。

Journal of Hydrodynamics 2007年第1期19卷 1-8页

作者： YOU yun-xiang shi qiang MIAO Guo-ping School of Naval Architecture Ocean and Civil Engineering Shanghai Jiaotong University Shanghai 200030 China.

An analytical method was proposed to analyze the radiation and diffraction of water waves by a bottom-mounted circular cylinder in a two-layer fluid. Analytical expressions for added mass and damping coefficients, as well as the wave excitation forces of the circular cylinder were obtained by an eigenfunction expansion method. The hydrodynamic forces on the bottom-mounted circular cylinder in a two-layer fluid include not only the added mass and damping coefficients, but also the wave forces of the surface and internal-wave modes. This is different from the case of a homogenous fluid. Some examples were given, showing that density stratification can have a relative large effect on these hydrodynamic forces over a wide range of frequencies.
