通过化学沉积法制备Ni-P、Ni-Mo-P单镀层以及与其成分相同的Ni-P/Ni-Mo-P双镀层。采用纳米压痕法和AFM分析测量镀层表面和截面的残余应力,并用电化学法评估镀层在10%HCl溶液中的腐蚀行为,以获得镀层残余应力与腐蚀行为之间的关系。结果表明:Ni-P单镀层和Ni-P/Ni-Mo-P双镀层表现为残余压应力,分别为241和206 MPa;Ni-Mo-P单镀层呈现出257 MPa的残余拉应力。残余压应力阻止镀层中孔洞的生长,保护镀层的完整性。Ni-P/Ni-Mo-P双镀层比它们的单镀层具有更好的耐蚀性。此外,镀层的应力状态影响其腐蚀形式。

为了对超声速、高超声速进气道内激波/边界层干扰现象进行有效控制,提出了一种结合次流控制的壁面鼓包控制激波/边界层干扰的方法,并对相关流动机理及参数影响规律进行了研究。结果表明:将次流控制与壁面鼓包相结合,利用鼓包前后存在的压差,将激波入射导致的分离区内的低能流引入鼓包下方的引流腔,在减少分离包内低能流的同时,促进分离包的再附着,有效地缩小了激波入射导致的边界层分离,改善了通道内的流动状态,降低了流动损失。同时,将引流腔中的气流从鼓包下游的吹气缝中喷出,对当地边界层起到了一定的能量补充效果,并避免了捕获流量的损失。相较于现有的壁面鼓包控制方案,结合次流控制后可以在较大激波入射范围内实现对激波/边界层干扰的控制,通道出口的总压恢复系数的最大改善幅度可以达到5%以上。此外,将引气缝布置在鼓包迎风面,并且当单条引气缝的宽度和间距固定不变,而引气缝总宽度和单条引气缝宽度之比不大于3时,可以获得较好的控制效果。

油井内压力及温度的测量是智能完井系统的重要组成部分。为了能在井下环境实现单点、压力温度双参量测量,且最高压力可达30 MPa,温度可达120℃,本文提出一种在圆心边孔光纤(side hole fiber,SHF)上刻写π相移光栅的压力温度传感器。首... 详细信息

油井内压力及温度的测量是智能完井系统的重要组成部分。为了能在井下环境实现单点、压力温度双参量测量,且最高压力可达30 MPa,温度可达120℃,本文提出一种在圆心边孔光纤(side hole fiber,SHF)上刻写π相移光栅的压力温度传感器。首先对边孔π相移光纤光栅同时测量压力及温度进行了理论推导,证明同时检测压力温度的理论可行性。其次,在理论的基础上,对SHF进行了仿真优化,并引入断裂极限限定条件,得到SHF的最优尺寸为孔中心距27μm,孔半径21.5μm。结果表明:SHF能实现单点双参量的测量,π相移光栅的引入提高了测量分辨率;SHF的孔半径越大孔越靠近纤芯,压力灵敏度越高,但考虑光纤断裂情况则并不是半径越大越好。该研究对特定压力测量范围下的边孔光栅压力温度传感器设计有指导意义。

A substantial fraction of miRNA^＊ species are conserved in animals and can repress activities of target genes. This study aims to investigate the miRNA^＊ species in duck skin by using Solexa sequencing. We obtained a total of 96 miRNA^＊ species in two skin small RNA libraries and identified 56 miRNA/miRNA^＊（miR/miR^＊） pairs. Nucleotide bias of miRNA^＊ indicated that the priority was C〉A〉U〉G for the first nucleotide and U〉C〉A〉G for the last nucleotide. Comparison analyses showed that 3＇-U accounted for a higher proportion in the 56 miR/miR＊ pairs. Among the top 20 expressed miRNA^＊ species, 17 were shared by two libraries and most of the miRNA^＊ species were highly conservative, especially in the ＂seed region＂, miR-199a^＊ were expressed highly in our samples, which was also previously shown abundant in mouse hair follicle. Furthermore, four miRNA^＊ species were predicted to target their genes in signal pathways of feather follicle development and feather morphogenesis despite very low levels.
