定期监测45°阶梯式溢流堰坝体上下的溶解氧及水质指标变化,研究阶梯式溢流堰对不同浓度污染水体有机污染及营养盐的影响。结果表明,水体经45°阶梯式溢流堰后,IMn、NH3-N、TP得到有效降低,当坝上的IMn低于19.00mg·L-1,IMn降低率较高,高于5.80%;当坝上的IMn高于19.00mg·L-1,IMn降低率较低,低于5.80%。当坝上NH3-N质量浓度小于19mg·L-1时,NH3-N去除率较低,低于5.00%,当坝上水体NH3-N质量浓度大于19mg·L-1时去除率较高,高于8.00%。水体经溢流堰后TP的降低值与坝上TP质量浓度呈显著的线性关系,线性方程为ΔTP=0.2015TPA-0.1999,但坝上TN浓度对TN去除率无直接联系。

ABM: To investigate the effects ofβ-aescin on apoptosis induced by transient focal brain ischemia in rats. METHODS: Rats were pretreated with β-aescin for 7 d and then subjected to brain ischemia/reperfusion (I/R) injury induced by a middle cerebral artery occlusion. After 2 h ischemia and 24 h reperfusion, Hematoxylin-Eosin (HE) staining, in situ end-labeling of nuclear DNA fragmentation (TUNEL) were employed to determine the level of apoptosis. The expressions of caspase-3 and Bcl-2 in the cortex were determined by immunohistochemistry and Western blot. The release of cytochrome c was analyzed by Western blot. RESULTS: The increased numbers of HE- and TUNEL-positive staining cells were significantly observed at 24 h after reperfusion. The immunoreactivity was inhibited by β-aescin (30, 60 mg/kg) (P2 expression was inhibited. β-Aescin (30, 60 mg/kg) markedly in

The path generated by a linkage in general deviates from the specified path. In this paper,the deviation is analyzed based upon the reliability concept and a reliability-based optimal synthesisprocedure is presented for path generating mechanisms. Both structural and mechanical errors areincorporated in the objective function. A four-bar path generating mechanism is considered fornumerical illustration and the results are compared with those obtained by deterministic *** expected, the presented approach is superior to the deterministic procedure.
