This study aimed to investigate the effects of phosphorylated-ovalbumin(P-OVA)at different concentrations(0.5%and 1.0%)on the gel properties of pork myofibrillar protein(MP).The results showed that the textural properties such as gel hardness,cohesiveness,springiness and chewiness were improved with P-OVA addition at 0.5%.The water holding capacity(up to 75.89%)and gel strength(up to 168.56 g·mm)of MP gel were markedly increased after P-OVA *** absolute value of zeta potential reached 13.85 mV and maximum hydrophobicity(15.2μg)resulted from the addition of 0.5%*** storage modulus(G’)and loss modulus(G’’)of MP gel were significantly increased from 50°C,and the G’and G’’significantly increased after 1.0%P-OVA addition,evidencing that the cross-linking effect of MP protein gel was *** addition,the P-OVA addition improved the structure of MP gel protein by reducing theα-helix,while increasing theβ-sheet and the r-value(the ratio between two ultraviolet second-derivative peak-to-trough distances),which further promoted the uniform and compact gel network *** work demonstrated that P-OVA is a highly effective modifier that significantly improves the quality of MP *** a view of practice,0.5%P-OVA is the optimal addition amount.

为研究超燃冲压发动机燃烧室与再生冷却通道的耦合传热特性,采用双向弱耦合迭代计算方法,研究燃烧室和冷却通道的特征参数对耦合传热特性的影响规律。结果表明:当量比的增加导致燃烧反应区域和壁面高温区域后移,当量比增大至0.75时,部分壁面高温区后移至超出燃烧段范围,在燃烧室的当量比设计时需考虑冷却通道范围的限制;喷射角度的增大会提高燃烧段壁面平均温度,喷射角度由30°增大到75°时,冷却通道出口裂解率由8%增长到11%;增大冷却剂的工作压力和流量能增强冷却剂的吸热能力,降低燃烧室内壁面温度,最大下降幅度约200 K。

为了研究焊接结构破坏过程中的宏细观损伤演化特征及其表征方法,以含细观裂纹的焊接构件为对象,采用X-CT(X射线计算机断层扫描)和电测技术同步记录试样内部细观结构和宏观力学性能变化过程.实验发现,试样变形过程中试样在弹性模量减小的同时,其内部细观裂纹不断萌生、扩展和聚合,扩展形态表现出显著的分形特征,且分形维数随试样塑性变形呈线性增加的趋势.综合考虑裂纹扩展形态的分形维数度量与裂纹扩展的物理意义,提出了一种多尺度损伤表征方法,以同时描述结构宏观损伤特性与内部细观裂纹扩展特性,并用传统的损伤量化方法进行验证.结果表明,新的多尺度损伤表征方法能够很好地描述细观裂纹到宏观损伤的多尺度演化过程.
