The results were as follows. At the temperature of 25~30C,initial pH value of 7.5~8.0,alkalinity of NaHCO3 concentration 1700mg/L, NH4+-N concentration of 150mg/L,aerations of 110rpm, cultured 24h,immobilized nitrite bacteria N4s NH4+-N removal efficiency reached 99.47%,accumulative volume of NO2--N was 116.65mg/L.

试验结果表明：固定化亚硝化细菌N_4在温度25～30℃，起始pH值7.5～8.0，摇瓶转速110rpm，碱度为NaHCO_3浓度1700mg／L，初始NH_4~+-N浓度150mg／L，培养24h，NH_4~+-N去除率达99.47％，NO_2~--N积累量达116.65mg／L。

The results showed that Acidithiobacillus ferrooxidans could effectively solubilise realgar and 16.3% arsenic dissolution could be achieved in 30 days under the conditions of pH 1.8 in Iron free 9 K medium (with additional 1.0g of ferrous iron per liter and 0.5% of realgar), 150 rpm, 30°C. The trace elements of Zn, Cu, Mg, Mn, Fe and Se et al. could also be effectively leached.

实验结果表明，氧化亚铁硫杆菌能够有效溶解雄黄中不溶性的硫化砷，30 ℃，pH1.8，以20%接种量接种驯化后的氧化亚铁硫杆菌BY-3条件下135r/min摇瓶浸出30天砷的溶出率可达16.3%，Zn、Cu、Mg、Mn、Fe、Se等有益微量元素都能够得到有效浸出。

Solution B: NaNO3 is added to a 50-mL volumetric flask in the amount necessary to obtain a concentration of 0.02 M.

溶液B：将所需量的NaNO3加到一个50-mL的容量瓶中，以获得一个浓度为0.02M的溶液

Because the water for treating sample three times had some loss, and it can not be completely collected in volumetric flask. Therefore, we diluted the extraction to the scale for acertaining the sampling volume to analysis the content of XXX.

需要翻译的部分：由于三次处理试样的水有少许损失，l并不能完全收集到容量瓶里面，为了确定采样量，我们将提取液稀释到刻度，以便分析XXX的含量。

The improved method selects the absorbing wavelength of 618 nm and the reaction time of 40 min, uses the NH4Cl-NH3 buffer solution (pH=8.0) and BTB alcohol solution (0.4 g/L) respectively of 5 ml and 1.5 ml in the 50 ml volumetric flask, and can test the concentration of imidazolinyl-quaternary-ammonium-salts in range of 0 mg/L to 80 mg/L.

利用改进的显色反应法检测时，吸收波长选择618 nm，显色时间40 min， 5 ml容量瓶中NH4Cl-NH：缓冲液(pH=8.0)和BTB乙醇溶液(0.4 g/L)的添加量分别为 5 ml、15 ml，适用检测的咪唑啉季铵盐浓度为0~80 mg/L。

Four pairs will each prepare one of the following four solutions made by adding the appropriate quantity of solid NaNO3 to the specified volumetric flask and diluting to the mark with stock solution A.

四对人中每一对都要将适当量的固体NaNO3加到指定的容量瓶中，然后稀释至跟储备溶液A相同的刻度以配制以下四个溶液中的一个。

The favorite cultural conditions are developed as the following: the initial charge is 15 g in 500 mL Erlenmeyer flask; initial ratio of water to solid is 1.7:1.0 (V/W, rice hull excluding), inoculating quantity is 7 mL, culture temperature is 28℃.

结果表明，链霉菌Men-myco-93-63产孢的适宜条件为：装料量为15 g/500 mL三角瓶，初始水料比为1.7：1.0(V/W，不计稻壳质量)，液体接种量为7 mL，培养温度为28℃。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
