The McAbs subtype was IgG1.The ascite titer was 10-7.The McAbs had no cross-reaction with some analogues of nitroaniline.

该抗体亚类为IgG1，制备的单克隆抗体腹水效果评价达10-7，与其他硝基苯胺结构类似物无交叉反应。

In an earlier investigation [14], chemostats were inoculated with surface water from the same location as in the present study and grown for 40 days on a rich medium containing a mixture of vitamins and 3 mg/l of the fungicide 2,6-dichloro-4-nitroaniline.

在一次更加早期的调查[ 14 ]， chemostats 被接种了与水面从地点和一样在本研究中和增长40 天在一个富有的媒介包含混合物维生素和3 毫克杀真菌剂2，6 dichloro 4 硝基苯胺(dichloran 的) l 。

Add 100-150g of finely crushed ice and stir until the m-nitroaniline has been converted into the sulphate and a homogeneous paste results. Cool to 0-5°C by immersion of the beaker in a freezing mixture, stir mechanically and add a cold solution of 18g(0.26mol) of sodium nitrite in 40 ml of water over a period of 10 minutes until a permanent colour is immediately given to potassium iodide-starch paper: do not allow the temperature to rise above 5-7°C during the diazotisation.

加入100-150g碎冰，搅拌至m-硝基苯胺成硫酸盐，把烧杯浸入到冷冻液中冷却到0-5°C，机械搅拌下于 10 min内加亚硝酸钠冷溶液（由18g(0.26mol)亚硝酸钠和40 ml 水组成），直到用淀粉-碘化钾试纸测试时，能使该试纸立即显色且不褪色：在重氮化反应时不允许温度超过5-7°C。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
