Effect of a direct magnetic field on the interfacial microstructure between molten aluminium and solid iron

Many processing techniques, such as hot dip aluminizing, bimetal formation, liquid metal corrosion, cementing, welding and diffusion bonding, are basically dependent on interfacial reactions [1-3]. It is therefore important to investigate the formation and growth of intermetallic layers at the interface. There have been several studies carried out to examine chemical compositions and growth kinetics of intermetallic layers in the Al-Fe system [4-9]. Most authors have come to an agreement that…     

Advances in the research of nitrogen containing stainless steels

The current status of nitrogen containing stainless steels at home and aboard has been introduced. The function and existing forms of nitrogen in the stainless steels, influence of nitrogen on mechanical properties and anti-corrosion properties as well as the application of nitrogen containing cast stainless steels were discussed in this paper. It is clear that nitrogen will be a potential and important alloying element in stainless steels. And Argon Oxygen Decarbonization (AOD) refining can provide an advanced manufacture process for nitrogen containing stainless steels with ultra-low- carbon and high cleanliness.

分离式长电偶极子稀疏阵列的相干信号多维参数联合估计

由长电偶极子或大磁环组成的大尺寸电磁矢量传感器(ElectroMagnetic Vector Sensor,EMVS)比小尺寸EMVS辐射效率更高,研究其参数估计算法有助于推动EMVS的实装化应用.该文针对分离式长电偶极子稀疏阵列相干目标参数估计问题,提出高精度无模糊的多维参数闭式解算法.首先利用空域旋转不变性和单个矢量传感器内部属性得到方向余弦的高精度周期性模糊估计值,然后借助单个矢量传感器导向矢量推导出2维波达方向粗估计值,最后通过解模糊得到高精度无模糊的多维参数估计值.该方法规避了传统极化平滑算法的极化信息损失和迭代搜索过程,且能实现参数自动配对.计算机仿真结果表明了所提算法在分离式长电偶极子线阵中解相干的有效性.

脂肪含量对低盐猪肉凝胶品质的影响

以未添加磷酸盐的低盐猪肉凝胶作为研究对象,考察脂肪添加量(0～20%)对猪肉凝胶保水、质构和色泽的影响。结果显示,脂肪添加量在15%～20%范围内,凝胶保水性显著增加(P<0.05);添加5%以上的脂肪,可显著提高猪肉凝胶的L*值(P<0.05);在脂肪添加量不高于5%条件下,猪肉凝胶可形成良好的硬度、弹性、凝聚性和咀嚼性,并能保持较好的红度值(a*值),利于开发低脂猪肉制品。
