Glycolate oxidase (EC 1. 1. 3. 1, GO) was purified by 137. 4 fold from leaves of Brassica campestris L. ssp. chinensis var. utilis and the specific activity attained 130.9 U/mg. protein. Chromatography of purified GO through Sephadex G-200 showed two symmetric peaks of both protein and activity, which overlapped fully with each other. Further with electrophoresis on agrose plate, a protein spot and an activity spot were detected in electrophoretogram after respective staining, and the spot of protein covered that of activity, which indicated that the purified enzyme was of a high quality.
从菜心叶片中纯化了乙醇酸氧化酶,比活性达130.9 U/mg,纯化倍数为137.4倍;纯化酶经Sephadex G-200凝胶过滤显现单一而对称的蛋白吸收峰和活性峰,且两者完全重叠;进一步经pH 8.3缓冲系统的琼脂糖平板电泳、染色,各在负极端出现一个活性斑点和蛋白染色斑点,且两者的位置完全对应;表明纯化的菜心叶片乙醇酸氧化酶已达到较高的纯度。

The results show that the density of gritstone is decreased gradually as the temperature increasing; so that it can be ignored; the longitudinal wave velocity is linearly decreased when the temperature increasing, and decrease rate of it follows the law of conic; R is one temperature point, which makes the law of tensile strength of gritstone after high temperature follows the law of parabola; and the maximal tensile strength appears when the operative temperature is R. After the temperature is higher than 700 ℃, tensile strength is small and change range is small when the temperature is increased.
结果表明,高温后粗砂岩的密度随试验温度的升高减小幅度很小,几乎可忽略不记;高温后试件中纵波波速的传播随温度升高基本呈线性降低,而减小率呈二次曲线规律变化;存在一个温度点R,使高温后试件的抗拉强度呈开口向下抛物线关系变化,且在R温度作用后试件抗拉强度达到最大;当试验温度大于700 ℃后,试件的抗拉强度变得很小,且当温度升高时变化幅度也很小。

The numerical result shows that the contributions from the interface optical phonon mode with higher frequency and the LO-like half space mode to the binding energy and the Stark energy shift are important and obviously increase with increasing hydrostatic pressure, whereas the interface optical phonon mode with lower frequency and the TO-like half space mode are extremely small and are insensitive to the impurity position and hydrostatic pressure.
数值计算结果表明,高频支界面声子模和类LO半空间声子模对于结合能和斯塔克能移的影响是主要的,且随压力的增加而显著增大,而低频支界面声子模和类TO声子模的作用则很小,且对于杂质位置和流体静压力的变化不敏感。

At present, Chinas main method control classical swine fever is vaccine injection, that artificialactive immunization, As for it is no final conclusion that the difference of domestic CSF immuneeffects with advanced immunization and ordinary routine immunization. And it will take enormousmanpower and resources for farms to take advanced immunization, and there is a possibility of certainanaphylactic response. It is not easy extensive, the immune programme of each hoggery is difference.
目前我国防治猪瘟主要采取注射猪瘟疫苗的人工主动免疫方法,由于国内对猪瘟超前免疫和普通常规免疫两种方法在免疫效果上的差别没有定论,且养殖场采取超前免疫措施需要大量的人力及物力,且存在一定的过敏反应,不容易广泛开展,因此各个养猪场所采取的猪瘟免疫程序各不相同。
