水流通过坝体和坝基时存在压力和梯度,这在大坝工程设计中已视为重要因素。但是,在土石坝设计时往往会遇到抵御不利大坝安全因素的排水系统的选型和设计问题。目前,很多工程中虽存在一些效果不错的排水系统,但其缺乏渗流和浸润线位置的控制,可能会对工程安全产生威胁,或使渗流控制措施达不到经济有效的目的。为此,本文基于均质土坝实验研究取得的成果,研究出在竖向排水体中的渗流量的控制方法,采用这种方法可以对土石坝进行更好的管理。

AIM: To detect whether the combination of vincamine, thioctic acid and lutein will improve the retina and optic nerve functions in cases of an opaque media with an optic nerve and/or a retinal defect or ***: Totally 2000 patients(2000 eyes) of corneal opacities with defects in the optic nerve or/and the retinal functions were studied. Every patient received three types of drugs: thioctic acid with cyanocobalamine, vincamine, and lutein. The drugs were given daily for 3-12 mo according to patient’s responses. Full field flash electroretinogram(ERG) and flash visual evoked potential(VEP) were done before treatment and at 1, 3, 6, and 12 mo sequentially. Patients were followed up for 12 ***: In the 2000 eyes, 1000 eyes had both moderate optic nerve and retinal function defects;and 840 eyes out of the 1000 improved with the medical treatment. Another 500 eyes out of the 2000 eyes had extinguished retinal function with normal optic nerve function and only 125 eyes of them improved. The 290 out of the 2000 eyes had severe defects in optic nerve with normal retinal function and 130 of them improved. Another 210 eyes have mild optic nerve and retinal function defects and 194 ***: The combination of vincamine, thioctic acid with cyanocobalamine, and lutein improved both retina and optic nerve functions mainly in mild and moderate defect than in severe cases.

Rechargeable zinc-air batteries(ZABs)are a promising energy conversion device,which rely critically on electrocatalysts to accelerate their rate-determining reactions such as oxygen reduction(ORR)and oxygen evolution reactions(OER).Herein,we fabricate a range of bifunctional M-N-C(metal-nitrogen-carbon)catalysts containing M-Nx coordination sites and M/MxC nanoparticles(M=Co,Fe,and Cu)using a new class ofγ-cyclodextrin(CD)based metal-organic framework as the *** the two types of active sites interacting with each other in the catalysts,the obtained Fe@C-FeNC and Co@C-CoNC display superior alkaline ORR activity in terms of low half-wave(E1/2)potential(~0.917 and 0.906 V,respectively),which are higher than Cu@C-CuNC(~0.829 V)and the commercial Pt/C(~0.861 V).As a bifunctional electrocatalyst,the Co@C-CoNC exhibits the best performance,showing a bifunctional ORR/OER overpotential(ΔE)of~0.732 V,which is much lower than that of Fe@C-FeNC(~0.831 V)and Cu@C-CuNC(~1.411 V),as well as most of the robust bifunctional electrocatalysts reported to *** X-ray absorption spectroscopy and density functional theory simulations reveal that the strong electronic correlation between metallic Co nanoparticles and the atomic Co-N4 sites in the Co@C-CoNC catalyst can increase the d-electron density near the Fermi level and thus effectively optimize the adsorption/desorption of intermediates in ORR/OER,resulting in an enhanced bifunctional electrocatalytic *** Co@C-CoNC-based rechargeable ZAB exhibited a maximum power density of 162.80 mW cm^(−2) at 270.30 mA cm^(−2),higher than the combination of commercial Pt/C+RuO2(~158.90 mW cm^(−2) at 265.80 mA cm^(−2))*** the galvanostatic discharge at 10 mA cm^(−2),the ZAB delivered an almost stable discharge voltage of 1.2 V for~140 h,signifying the virtue of excellent bifunctional ORR/OER electrocatalytic activity.
