The effects of heat - killed Lactobacillus preparation on the immunity of Zhu - si broiler 热灭活(HK)乳杆菌制剂对竹丝肉鸡免疫性能的影响
Based on numerical methods, a mathematical model of two-dimensional unsteady heat transfer is developed to simulate the heat transfer of killed ingot, and verified by the experiment measurment in a factory. 通过数值计算方法,建立了镇静钢锭热过程的数学模型,并通过现场的实际测定对其进行了修正。
HIV resistance to the external environment is weak, leaving the body will be lost soon after the infectious, very sensitive to heat, 60 ℃ or more can be killed. 艾滋病毒对外界环境抵抗力较弱,离开人体后很快会失去传染性,对热很敏感,60℃以上就可被杀死。
