本文基于状态重置的改进型动态抗饱和补偿方案,研究了具有单输入的线性饱和系统的抗饱和控制问题.相比较于传统的动态抗饱和补偿方案,当执行器不饱和时,改进的动态抗饱和补偿方案把动态抗饱和补偿器的状态重置为零.所以当执行器不饱和时,改进的动态抗饱和补偿器将不会对控制器进行补偿.进一步的,提出了一个时间依赖的Lyapunov函数来分析闭环系统的稳定性,并以LMIs的形式给出了闭环系统的控制综合条件.最后,通过压电纳米运动平台验证了所提出的改进型动态抗饱和补偿方案的有效性.

本文认为,当前我国工业化先行地区正面临新一轮的产业结构调整良机,重化工业发展是工业化先行地区经济加速时期不可逾越的阶段。以传统轻型加工业为主导的地区随着经济的不断发展,在新形势下面临着来自劳动密集型产业竞争力低下、经常性技术贸易壁垒、企业外迁和资本外流、产品在国际产业链条附加值低等方面的挑战。因此,经济“偏轻”工业化地区政府部门推进重化工业发展、实现产业升级,应该注意制定好促进地区产业发展的用地规划和产业规划;着力完善资源的产权和市场定价机制,推动资源节约型的重化工业发展;大力增强企业技术创新能力,作为推进调整结构的中心环节;积极推进以循环经济为基本理念的生态工业区域建设,实现地区经济的可持续发展;维护并积极参与全球资源、技术与产品的自由贸易体制,利用两种资源两个市场促进产业升级。

作为一种心理学理论体系和治疗方法,弗洛伊德的精神分析自提出之日起就备受争议。在历经几次大的学派分离和理论修正之后,当代精神分析理论和方法改变了古典精神分析的本质特征,远离了它的生物学和物理学假设。精神分析的多次裂变既带来了其元心理学的分裂,也带来了新精神分析的发展。经过历次的修正,客体化倾向已经成为精神分析发展的主要方向,它既是对传统精神分析的颠覆,也是对弗洛伊德理论的新发展。在这种倾向的指引下,还会有一批跟随者继续对弗洛伊德的精神分析理论进行修正,并不断发展符合时代潮流的新精神分析理论。

预测船体总段船台合拢的焊接变形,对于船体制造工艺设计和精度造船具有重要的意义。文章在掌握固有应变概念的基础上,利用上海交通大学和日本大阪大学共同开发的基于固有应变的Weld-sta软件,对大型集装箱船的船体总段船台合拢焊接变形进行了预测。预测结果表明船台合拢总收缩变形量为50.339 mm,模拟计算结果与实际建造结果吻合,验证了固有应变为基础的弹性板单元有限元预测法在船体总段合拢焊接中应用的可行性,从而为船体总段合拢时补偿量或收缩量的确定提供数据支持和理论指导。

BACKGROUND : The importance of nitric oxide (NO) in the pathogenesis of portal hypertension (PHT) has been extensively studied, but whether or not prostacyclin (PGI2) plays a role in formation and development of hyperdynamic circutatory state in PHT has not been verified. The present study was undertaken to investigate the possible interaction between prostacyclin (PGI2) and nitric oxide (NO) in the hyperdynamic circulatory state of rats with chronic portal hypertension (PHT), by measuring the hemodynamic changes and expression of cyclooxygenase (COX) mRNA in vessels and small intestine after administration of Nω- nitro-L-arginine (L-NNA) or indomethacin (INDO) either in the short-term (7 days) or long-term (15 days). METHODS: Ninety-seven male Sprague-Dawley rats were divided into three groups: intrahepatic portal hypertension (IHPH) induced by injection of CCl4, prehepatic portal hypertension (PHPH) induced by partial stenosis of the portal vein, and sham-operated controls (SO). Animals of each group received L-NNA or INDO either for 7 or 15 days, with saline as control. Splanchnic hemodynamics was measured by the radioactive microsphere technique. The concentration of NO in serum was determined as the nitrate; nitrite ratio (NO2-/NO3-, μmol/L) by a colorometric method, and that of PGI2 was measured by specific radioimmunoassay for its stable hydrolysis product 6-keto-PGF1α (pg/ml). The reverse transcription- polymerase chain reaction measured the levels of COX-1 mRNA in the superior mesenteric artery, thoracic aorta, and small intestine of these ***: Compared with SO rats, COX-1 mRNA expression and the concentrations of plasma 6-keto- PGF1α and serum NO2-/NO3- were enhanced in both IHPH and PHPH rats; splanchnic vascular resistance (SVR) decreased, but portal venous inflow (PVI) markedly increased (P<0.05). Seven or 15 days of L-NNA treatment reduced COX-1 mRNA expression in these vessels and the small intestine, concomitant with a significant decrease i

BACKGROUND: By detecting hemodynamic changes, concentration of plasm prostacyclin ( PGI2) and expression of cyclooxygenase( COX) in vasculature and splanchnic tissues, we evaluated the relative contributions of PGI2 and COX mRNA expression to the hyperdynamic circulatory state in chronic portal hypertensive rats. METHODS: Fifty male Sprague-Dawley rats were divided into 3 groups: intrahepatic portal hypertension (IHPH, n = 18) by injection of CCl4, prehepatic portal hypertension (PHPH, n = 18) by partial stenosis of the portal vein, and sham-operated controls (SO, n =14). Splanchnic hemodynamics was measured by radioactive microsphere techniques and the concentration of PGI2 was detected by specific radioimmunoassay for its stable hydrolysis product 6-keto-PGF1α. Semi-quantitive reverse transcriptase-polyme-rase chain reaction (RT-PCR) was performed to measure the levels of COX-1 mRNA and COX-2 mRNA in the thoracic aorta, superior mesenteric artery( SMA),and small intestine of IHPH, PHPH and SO rats, respectively. RESULTS: Hyperdynamic circulatory state was characterized by increased splanchnic blood flow and decreased splanchnic vascular resistance in IHPH and PHPH rats. The concentration of plasma 6-keto-PGF1α ( pg/ml) in IHPH (1093.75 ± 142.15) and PHPH (897. 42 ± 53. 29) rats was significantly higher than that in SO rats (730.13 ± 98. 67) (P <0.05). The expression of COX-1 mRNA in the thoracic aorta, SMA and small intestine was enhanced, whereas COX-2 mRNA expression was not detected in either of these vessels or the small intestine. The plasma 6-keto-PGF1α concentration and the expression of COX-1 mRNA in these vessels and the small intestine were closely correlated with such hemodynamic parameters as portal venous inflow (PVI), splanchnic vascular resistance (SVR) and free portal venous pressure (FPP) (P<0.05). CONCLUSION: The expression of COX-1 mRNA and the levels of PGI2 were closely related to the hyperdynamic circulatory state of portal hypertensive rats.
