皇冠分解和NT算法长久以来被认V1为是在参数化点覆盖的求核问题中有着广泛应用的两种相互独立的方法。NT算法将给定的图分成V0,V1和V1/2三部分,将V0和V1移除从而完成图的分解。而皇冠分解则是找到尽可能多的皇冠结构,删除这些皇冠以降低图规模。最近的研究结果表明NT算法和皇冠分解存在很强的内在联系:NT算法中的V0,V1部分正好构成一个皇冠结构。本文进一步研究了皇冠分解和NT算法的内在联系,提出了严格皇冠和非严格皇冠的概念,提出了一般图中存在皇冠的判定定理,证明了NT算法可以移除一般图中存在的所有严格皇冠。论文还提出了一种扩展NT算法,能够移除图中的所有严格和非严格皇冠,即证明了用扩展NT算法处理过的图中将不会存在任何皇冠结构。

为探究超声波、超高压处理对鲣鱼肌原纤维蛋白(myofibrillar protein,MP)功能性质的影响,提升鲣鱼的附加值,以鲣鱼肌原纤维蛋白为原材料,对其进行不同的超声时间及超高压强度处理,提高肌原纤维蛋白的功能性质。研究结果表明,在一定的超声时间内,MP的溶解度及乳化性随超声时间的延长而增加。经不同的超高压强度处理后,MP的溶解度在200~300 MPa达到最大值,乳化性在200 MPa达到最优。温度扫描过程中,弹性模量随超声时间的延长及压力强度的增加而下降。并且超声波、超高压处理均会影响蛋白分子质量。
