5.The type I callus displayed 2-fold level of growth rate,and 1.5-fold and 1.8-fold level of UBE,compared with the II and III types of callus. The II and III types of callus had higher levels of ROS. The type III callus had 8-fold higher contents of H_2O_2,and 3-fold higher level of O~( · - )_2 than those in the type I callus.
I型愈伤组织的生长速率约是II型和III型的2倍,UBE强度是II型和III型的1.5倍和1.8倍,但II型和III型愈伤组织的活性氧代谢水平较强,III型中-H2O2和O·2的水平分别是I型的9倍和4倍。
6.The results showed that brucella IgG antibody GMT of patients with acute bracellosis were 4.5-fold higher than the chronic cases and the SPRIA were 15-fold more sensitive than SAT. When detecting the brucella IgG antibodies in sera of calves by double antibody SPRIA vaccinated with S~2 vaccine. the antibody GMT in prior and post immuniged animal were 15-5-fold more sensitive and 20-5-fold more sensitive than CFT and SAT respectively.
结果表明,应用SPRIA检测急性布病病人,其IgG抗体GMT比慢性病人高4.5倍,其灵敏度比SAT法高15倍,应用双抗体SPRIA检测猪2号布氏菌苗免疫前后犊牛的血清抗体,其免疫前抗体GMT分别为CFT和SAT的15倍和5倍,免疫后也分别高出20倍和5倍左右。
7.Methods: Wistar rats, 1 month after stopping lactation, were divided into 6 groups and given by different concentrations of iodine (KI) which were Low iodine(LI), normal iodine(NI),5 fold high-iodine (5HI), 10 fold high-iodine (10HI),50 fold high-iodine (50HI),100 fold high-iodine (100HI).
方法：取断乳后一个月的Wistar大鼠，给予不同浓度的碘化钾，分为6组：低碘组(LI)、适碘组(NI)、5倍碘组(5HI)、10倍碘组(10HI)、50倍碘组(50HI)、100倍碘组(100HI)。
8.According to the self-similarity Characteristic of fold, the fractal distnbution of fold is an-alysed in the term of fractals and the complex shapes of folds are simulated firstly in the paper on the theory of fractal interpolation ( Michael Barnsley, 1986). Every sort of fold can be simulated in terms of interpolation points (x, y) and vibration coefficient d. On the basis of fractal simulation, the fractal classification of complex degree of fold is proposed.
本文根据褶皱的白相似性特征,引用分形概念,分析褶皱的分形分布特性,并利用MichaelBamsley（1986）的分形插值理论首次模拟褶皱的复杂形态,主要利用插值点（x、y）和褶皱扰动系数d模拟各种褶皱,在此基础上,提出褶皱复杂程度的分形分类方案。
