当水样中季铵盐浓度小于120mg/L，羟乙基纤维素浓度小于220mg／L时，它们不具生物毒性，可作为营养物质被微生物利用。

ResultThe differences of the effects onthe germination of 2 group seeds in afterripening and GA3treatments reached at significant level.

结果后熟、GA3处理对2组种子发芽情况的影响差异达显著水平，后熟分别使发芽率由6.67%、7.78%，提高到21.33%、33.33%；GA3处理，发芽率随GA3浓度的增加，呈现低、高、低的趋势，以GA3200mg/L处理的种子萌发效果最佳；温汤浸种、KNO3处理对2组种子发芽情况的影响差异达极显著水平，其中温汤浸种处理的种子，发芽率随水温的升高而升高，以70℃水浸种后萌发效果最优，发芽率分别由21.33%、33.33%，提高到73.33%、90%；KNO3处理组，发芽率在处理浓度为250mg/L时为最佳水平。

Effects of Hg2 on agamogenesis of Egeria najasWhen Hg concentration was above 1.50mg/L, leaf of shoot fragment faded severely, compared to the control even the sprout also faded much.

Hg2 浓度l 。oom留L实验组中的侧枝新芽长度随着Hg2 浓度的增加而缩短，平均新芽长度在】。ocm以下。

The minimum inhibitory concentration was determined by serial dilution in the same type of agar, with concentration ranging from 5, 10, 25, 50, 75 and 100 mg/ml.

最低抑菌浓度测定在同一类型的琼脂稀释系列不等，5，10，25，50，75和100毫克/毫升的浓度。

DOAS can be used not only to the measurement of air pollutants near the surface, but also to the measurement of column density of air pollutants, even in the global monitoring of air pollution by satellite instruments.

这种方法不仅可以用在大气污染气体浓度的近地面测量上，还可以用来测量大气污染气体的柱浓度，以及用到卫星仪器对大气污染状况的全球测量上。

The results show that the Albizzia julibrissin Durazz had a stronger alkaline tolerance, the lethal and half lethal concentrations of alkaline to Albizzia julibrissin Durazz were 147.33 mmolL^(-1), 78.30 mmlL^(-1), respectively.

结果表明，合欢树种的耐碱能力较强，半致死浓度为78.30 mmolL^(-1)，致死浓度为147.33 mmolL^(-1)。

The results showed:(1) Through glycosylated orthogonal test, When the substrate concentration is 1:2, glycosylated temperature is 60℃, the enzyme dosage is 0.5%and glycosylated time is 6 hours, glycosylating was at best, and the sugar concentration was 33%(2) through fermentation orthogonal test, when adding the yeast is 2.0%, proportion of Rhodiola and glutinous rice is 1:1, the temperature is 28℃, and fermentation time is seven days, alcoholicity of the wine was the highest and sensory evaluation was the best..

本文立足加工高品质的红景天糯米保健酒，主要对糖化条件，发酵工艺参数的确定，后发酵温度的确定，稳定性试验，膜过滤试验条件，营养成分分析等方面进行系统的研究，结果表明：(1)通过糖化正交试验，在底物浓度1∶2、糖化温度60℃、酶用量0.5％、糖化6h时糖化效果最好，糖液浓度33％；(2)通过发酵正交试验，在酵母添加量2.0％、红景天糯米比1∶1、发酵温度28℃、发酵时间7天生成的酒度最高，感官评价最好；(3)通过后发酵试验，选择10～15℃温度下后发酵，酒体澄清，感官评价最好；(4)从对红景天糯米酒稳定性分析中得知：酒体在低于-6℃时略有絮状物出现，酒体混浊沉淀的主要原因可能是蛋白质。

The results showed: the Berberis heteropoda pigment could effectively inhibit the growth of theE scherichiac oli, the calyx pigment ofP hysalis alkekengi coulde ffectively inhibit the growth of the Bacterium proteus, the concentrated liquid of Rhodiola sachalinensis could effectively inhibit the growth of the Bac.

结果发现：小檗色素对大肠杆菌抑菌作用最强，酸浆花萼色素对变形杆菌抑菌作用最强，红景天浓缩液对枯草芽孢杆菌抑菌作用最强，小茴香浓缩液对四种待试菌无抑菌作用；小檗色素对四种待试菌的最低抑菌浓度和最低杀菌浓度分别为：枯草芽孢杆菌MIC2。

Low concentration of allyl alcohol helped to increase the reaction rate and high concentration of H2O2 could decrease the selectivity to glycidol using water as a solvent.

当催化剂用量一定时，以水为溶剂，较低的烯丙醇浓度更有利于反应的进行，而较高的双氧水浓度则会降低产物的选择性。
