The changes of nutrition in milk treated with different technologies are also determined. Results showed that, 1 higher pressure, longer holding time and more alternative times favour a larger destruction of microorganisms; 2 the combined effect of hurdle technology and pressure on the destruction of microorganisms in fresh raw milk is more effective than only using pressure treatment, among which the effect of ε-polylysine on inactivation of microorganism in fresh raw milk is more effective than that of Nisin with the same concentration of 100mg/L; 3 the whole proteins in milk treated by the different types of sterilization have been detected by SDS-PAGE electrophoresis, and comparing with the whole proteins' electrophoretogram of fresh raw milk, we found that the first spectrum band near the negative pole was disappeared and the colours of the second spectrum band was tint in UHT, pasteurism and 500MPa treated milks, which was suggested that some proteins' subunits were dissociated, but the 400MPa treated milk showed the similar eletrophoretogram with the fresh raw milk; 4 the loss of threonine, VA and VC in high pressure treated milk was more less than those in pasteurism treated milk, in particular threonine and VA were almost retained, and the contents of VB1 and VB2 in the former are also more than that in the latter; 5 high pressure treated milk had longer shelf life than pasteurism treated milk, extending the sale semidiameter of milk.

压力越高，保压时间越长，交变次数越多，杀菌效果越好；2）采用栅栏技术对牛乳中的微生物具有更有效的杀菌作用，其中相同浓度的（终浓度100mg/L）ε-聚赖氨酸较Nisin具有更强的杀菌效果；3）利用SDS-PAGE电泳研究了不同杀菌方式对牛乳总蛋白的影响，发现经UHT、巴氏和500MPa交变处理的牛乳与生鲜牛乳相比其总蛋白电泳图谱靠近负极方向第一条谱带消失，第二条谱带颜色变浅，由此推测经上述处理后牛乳中有一些蛋白质的亚基发生了解离，而经400MPa交变处理的牛乳与生鲜牛乳的总蛋白电泳图谱相似；4）超高压牛乳营养成分与生鲜牛乳相比，苏氨酸、VA、VC在超高压处理中受到的破坏明显比巴氏杀菌小得多，特别是苏氨酸和VA几乎完全被保留下来，而VC含量也要比巴氏奶高出25%以上，对于VB1、VB2，检测数据也表明，超高压灭菌对其破坏要比巴氏灭菌小，其含量分别比巴氏杀菌牛乳高出9.5%和2.6%；5）与巴氏杀菌乳相比，超高压杀菌有助于延长牛乳的保质期，扩大牛乳的销售半径。

结果表明：影响红叶石楠插穗生根的主导因素是激素种类，其次是插穗类型和扦插基质，激素质量浓度的影响最小；激素IBA处理的插穗生根率极显著(α=0.01)优于NAA和GRR，绿枝中部和上部插条生根率极显著(α=0.01)优于下部，扦插在基质A1和A2更易生根。

Orthogonal experiment under special condition showed that modifier M has marked effect on properties of no bake sand. Other factors such as modifier B,phosphate concentration and aluminum hydroxide have some impact on properties of binder. It can be found by experiments that strengths of no bake sand are raised notably by binder that modified by modifier B. Modifier B can reduce the strength of no bake sand at high room temperature apart from condition of low room temperature that it can accelerate the reaction and strengthen the sand. Modest content of modifier M in binder has some improvement to anti-wettability of sand. But modifier B has not such notable effect. Electronic microscope shows that near cracks in no bake product there are fibrous shape substances formed when the samples are moistured in high humidity air for sometime.

通过改性剂B对粘结剂自硬砂的性能影响试验发现，改性剂B能显著提高粘结剂自硬砂的强度，在0℃左右很低的环境温度下改性剂M有利于提高自硬砂的反应速度和砂型强度外，但在较高环境温度下，改性剂M均降低粘结剂自硬砂的强度，但是适量的改性剂M有利于改善自硬砂的抗吸湿性，而改性剂B对于改善自硬砂的抗吸湿性的作用不如改性剂M明显，电镜观察发现抗吸湿性较好的自硬砂在高湿度下存放一定时间后，在粘结膜裂纹处会形成一种绒毛状物质，该物质对裂纹具有愈合作用，这种绒毛状物质中具有改性剂M中的某种成分，且含量很高，由此说明改性剂M对提高抗吸湿性有利。
