No significant impact was measured on growth of Gomphidius viscidus and Laccaria bicolor under the treatment of 5.0 mg/L DDT and on growth of Boletus edulis under the treatments of 5.0 mg/L and 25.0 mg/L DDT.

在25.0mg/L的DDT处理下,美味牛肝菌的生长没有受到显著影响,显示出了较好的耐受性,在高ρ处理下,铆钉菇的多酚氧化酶、漆酶和过氧化物酶活性显著增强,液体培养基pH下降幅度较大。

But because it does not need to receive further treatments—a shed made from treated wood would not need regular applications of creosote, for example—it should prove economical over its lifetime.

但由于它不需要进行进一步处理---比如说由处理过的木材制成的平房将不再需要进行定期的杂酚油浸处理,因此,在其生命周期内将被证明更加经济。

Among the various packaging conditions examined, black soybean or black soybean koji held with desiccant and deoxidant showed the highest retention of total phenolic compound, isoflavone and antioxidant activity.

在所测试之包装条件中,以含乾燥剂及脱氧剂之处理组保有最高量之总酚、异黄酮素与抗氧化活性,不添加任何食品保存剂处理组之含量与活性最低。

The results showed that flash distillation could effectively concentrate grape, and sugar content, acid content, total phenol content, polysaccharide content and chromaticity in claret by flash distillation increased markedly but color tone remained at a comparatively low level.

结果表明,闪蒸处理可以有效浓缩葡萄原料,闪蒸处理后的葡萄酒含糖量、含酸量、总酚含量、多糖含量和色度等均有显著提高,色调则保持在一个较低的水平。

There are some midst matters in wastewater, for removal of these matters the electrolyze time should exceed 30 min. The experimental results show that the bipolar packed bed cell has best treatment efficiency of phenol wastewater under condition that voltage is 10V, electrolyses time is 30 min, and velocity of flow is 1.03 cm/min.Basic on the study on treating of phenol wastewater, this paper carry on a research on treating of circuitry board film wastewater by bipolar packed bed cell.

本文在以上处理苯酚废水研究的基础上,论文研究了BPBC处理两种不同浓度得脱膜废水,试验结果表明,对于浓度较高的酸化气浮-光酚顿的出水,在外加氧化剂双氧水后,最佳处理工艺:槽电压8V,实际电解时间60min,双氧水的投加量为1倍理论药量,pH值为3,COD的去除率达到60%;在酸化气浮过程采用酸铜废液调节pH值将会降低COD的去除率。

Blanching at 80℃ for 10min before peeling, dipping treatment in compounded solution of browning inhibitor for 2 hours after slicing and drying at 50℃ were beneficial to the colour of yam product, because which could decrease the activity of peroxidase and polyphenol oxidase.

通过去皮前对山药进行热烫处理(80℃,10min),切片后立即用复合护色液浸泡处理(浸泡2h),可有效改善山药产品的色泽,其原因是这些处理能够显著降低多酚氧化酶和过氧化物酶的活性。

The yeast treated by ultrasonic wave hardly affect the ferm...

超声波处理的酵母菌对发酵进程影响不大,均能正常发酵,对发酵后的酒样影响较大,经方差分析发现:酒度间存在显著性差异,超声波处理的酒度大部分降低,个别升高;残糖含量差异极显著,经超声波处理样品残糖含量均比对照高;各样品的总酸和挥发酸含量差异显著;超声波对总酚含量的影响不明显,对蛋白含量影响较大。

The inhibition effect of different protective coloration solution for Herba Cistanches polyphenol oxidase anzymatic activity was studied.

Pentachlorophenol is one of the most toxic organic pollutants and is difficult to be degraded among the chlorophenoxies.

五氯酚是氯酚族中最具毒性和最难降解的有机污染物,其废水的处理一直受人关注。

In this study, Cryptomeria japonica was liquefied in phenol with H2SO4 and HCl as a catalyst. The epoxy resin was synthesized from epichlorohydrin and bisphenol A with the molar ratio of 5/1. Blending resins were prepared by mixing the liquefied Japanese cedar and epoxy resin with weight ratios of 30/100, 50/100 and 70/100, and the triethylene tetramine was added as a cross-linking hardener. The effect of mixing ratios of liquefied Japanese cedar to epoxy resin and amount of hardener added on the reactivity of blending resins and the properties of cured resins were investigated. Furthermore, polysiloxane and rice husk were added as foaming agent and filler, respectively, to the epoxy resin and blending resins. The foaming process, the bubbles shape, the mechanical properties, and the thermal stability of the epoxy foams were investigated.
