The graphic carbon nitride/polyaniline(g-C3N4/PANI)hybrid composites were successfully synthesized by a facile in situ polymerization process under ice water bath.The photo-catalytic activities of the g-C3N4/PANI composites were evaluated by using oxytetracycline(OTC)as model pollutants.The optimal g-C3N4/PANI composite(5％PANI:the g-C3N4/PANI hybrid with 5 wt.％of PANI)showed an enhancement degradation rate of 5-fold compared to that of conventional g-C3N4 under simulated-sunlight irradiation.In addition,the 5％PANI demonstrate significantly photocatalytic evolution H2 rate(163.2 μmol/(g-hr))under the vis-ible light irradiation.Furthermore,based on the results of optical performance and electro-chemical testing,a possible mechanism was proposed,indicating that the incorporation of PANI into the traditional g-C3N4 can effectively tune the electronic structures,improve the photo-generated electrons-holes separation and enhance extensive absorption of visi-ble light.Such a g-C3N4/PANI hybrid nanocomposites could be envisaged to possess great potentials in practical wastewater treatment and water splitting.

利用ANSYS Workbench软件通过热-固耦合的方法对T型板结构的焊接过程进行模拟,获得不同应力边界条件下焊接残余应力及变形;然后将残余应力和变形分别添加到力学模型中,同时施加位移载荷研究具有焊接初始缺陷的T型板结构压缩极限强度。结果表明:在焊缝及热影响区存在着较大的拉伸应力,T型面板呈现角变形状态;在分别添加焊接残余应力和变形情况下,T型板极限强度都有下降,焊接残余应力对T型板极限强度的影响较焊接变形影响大。
为了解决集装箱船绑扎桥卧式总组占用大量施工场地的问题,以9400 TEU集装箱船为研究对象,提出了绑扎桥立式总组的方案。首先从分段划分、堆场压力等方面对该方案的可行性进行了分析,然后讨论了立式总组技术的具体做法和特点,最后从场地占用情况、变形情况等方面将新型立式总组与卧式总组的成效进行对比。研究结果表明:立式总组技术使总组效率提高了约20%,能减少约80%总组场地的占用,有效提高了大型集装箱船的建造效率。

以KP505螺旋桨为研究对象,利用CFD软件,基于RANS方法结合Realizable k-ε湍流模型开展螺旋桨水动力性能数值模拟,分析不同螺距、拱度径向分布对其水动力性能的影响。结果表明:随着螺距、拱度增大,推力和转矩均明显增加,导致螺旋桨单位面积平均推力增大,使得螺旋桨更易产生空泡现象;在中、低进速系数下,螺距越小,敞水效率越高;随拱度的增大敞水效率无明显变化。
