The molecular weight of dextransucrase measured by SDS-PAGE was 170 kDa ,which was similar to the enzyme from Leuconostoc mesenteroides. The enzyme had an optimum temperature between 25and 30℃ and an optimum pH of 5.4. It was relatively stable in the range of pH 5.0 to 7.0, but the stability declined rapidly as soon as the temperature rose over 35℃.
以蔗糖为底物,酶促反应的最适温度为25~30℃,最适pH值为5.4,动力学常数Km值为10.43 mmol/L;酶活在pH 5.0~8.0较为稳定,在室温(25℃)保藏4 天仍有59%的酶活力,4℃保存7周酶活力仅下降一半,但在35℃以上失活很快;Ca2+对催化作用有较大的促进,Mg2+有微弱的促进作用,K+对催化反应无影响,Cu2+的抑制作用最强。

The apparent density increased with the increase of Ag~+ complexing reagent A concentration, loadage, silver content and granularity, it firstly increased and then decreased with the increase of Cu/Ag ration, and it had no relation to other factors, and it was 1.3-1.4g/cm~3 usually.
3粉体的松装密度随Ag~+络合剂A浓度、装载量、含银量、粉体粒度的增加逐渐变大,随Cu/Ag比的增加先变大后变小,其它因素对松装密度都无明显的影响,均保持在1.3-1.4g/cm~3。

Due to the violation of the PA condition, the distributions of Wald statistics and Score statistics based on GLS estimators are noncentral $\chi^{2}$ distributions. The efficiency of testing based on the GEE method is largely influenced.
由于PA条件不成立,回归系数的GLS估计不再是渐近无偏的,构造的Wald和Score统计量的分布不再是中心卡方分布,从而对于检验的效率也产生了严重影响。

Calyciflorus clones were cultured at 15℃, 20℃, 25℃and 30℃with 3.0×106 cells/mL of Scenedesmus obliquus to investigate their differences in life history characteristics and their responses to increasing temperature.
结果表明,温度对萼花臂尾轮虫存活率和繁殖率的影响在不同克隆间存在着差异。20℃和25℃下,四个克隆轮虫的世代时间和净生殖率均分别无显著的差异;20℃、25℃和30℃下,四个克隆轮虫的平均寿命和出生时的生命期望亦然。

The RE of TP, COD and turbidity except NH4+-N in the aeration process by adding AS and PAM for enhanced chemical phosphorus removal increased by 7.3~59.2%, 5.0~20.3% and 10.9~34.7%, respectively. Given enough dissolved oxygen, the nitrification was not affected by adding AS and PAM in the dosage range of the study. The RE of TP, COD and turbidity by postpose coagulation were better than by simultaneous coagulation, however, coagulation and sedimentation equipments were needed in postpose coagulation process. Therefore simultaneous coagulation was more suitable for transformation of AB process for chemically enhanced phosphorus removal.
曝气过程中投加AS和PAM复配化学强化除磷,总磷、COD、浊度去除率分别提高了7.3~59.2%、5.0~20.3%、10.9~34.7%,但不能提高氨氮的去除率;在溶解氧足够时,本研究投加量范围的AS和PAM的加入对硝化作用无影响;后置混凝对TP、COD、浊度的去除效果优于同步混凝,但需增加混凝沉淀设备,因此同步混凝更适合于于AB工艺的化学强化除磷改造。

Almost all instances generated by standard models are unsatisfiable with probability tending to 1 as the number of variables approaches infinity. In 1998, a survey by Gent et al. shows that most previous experimental studies about random CSP models are affected by this result.
也就是说,在多数情况下,当变量数趋近于无穷大时,经典模型产生的所有实例几乎都是无解的。1998年,英国学者 Gent 等人的综述表明:以往大多数有关随机 CSP 问题的实验研究都受到了此结果的影响。

The mycelial growth of Rhizoctonia solani was promoted by vanillic acid and syringic acid at levels of 0.1~1 mM/L, and it was inhibited remarkably by p-counaric acid of over 1mM/L and modestly by ferulic acid. The radial extent of mycelia of Fusarium solani was increased significantly by ferulic acid of 0.1~1 mM/L and limitedly by p-coumaric acid. vanillic acid had paradoxcial effects on the growth, positively at low levels and negtively at high levels, on which Syringic acid had a slight effect.
试验结果显示:浓度为0.1~1mM/L的丁香酸对西洋参立枯丝核菌菌丝生长具有促进作用,香草酸也有一定的促进作用,但不呈浓度效应,浓度在1mM/L以上的香豆酸对其有显著的抑制作用,阿魏酸也有一定抑制作用;对于西洋参根腐菌,阿魏酸对其生长有明显促进作用,香豆酸也有一定促进作用,香草酸表现为低浓度促进,高浓度抑制作用,0.1~1mM/L丁香酸对其生长基本无影响。

The classics are books that exert a peculiar influence, both when they refuse to be eradicated from the mind and when they conceal themselves in the folds of memory, camouflaging themselves as the collective or individual unconscious.
经典作品是一些产生某种特殊影响的书,它们要么自己以遗忘的方式给我们的想像力打下印记,要么乔装成个人或集体的无意识隐藏在深层记忆中。
