查询词典 N-phenylaniline

As the N,N-dimethylformamide concentration is increased, the less soluble component becomes still less soluble, the behaviour tends to immiscibility and its activity coefficient increases.

随着 N，N－二甲基甲酰胺浓度的增加，溶解度较小的组分趋向于更加难溶，并且其活度系数增加。

The advantages of this method are:① the range of the exponent i of the undefined functions f from-N to N;② the indeterminate specific form of function so that we can get more new exact solutions.

点在于：①待定函数f的指数i的范围从N扩大到－N；②可以不必给出函数f的具体表达式求解方程，这样便于寻找更多的解。本文就是利用了这一特点，选择合适的参数，得到一些mBBM方程新的精确解。

For a N samples interpolation problem it conclude that we can interpolate them accurately using a three layer feedforward net with at most N hidden nodes.

对于给定N个样本点的插值问题，指出最多用含N个隐节点的三层网即可实现精确插值。

The EAE rats were induced by injecting subcutaneously an emulsion of GPSCH and CFA. In addition, each rat received an intracutaneous injection of pertussis. Albumin in serum and CSF samples was examined on the days of 4,6,8,10,12,14,16,18 and 20 p.i.. The integrity of BBB was assessed by caculating CSF to serum albumin quotient. At the same time the brains, spinal cords, thymus and inguinal lymph nodes were removed for paraffin sections cutting. These sections were used for HE staining and ICAM-1 semiquantitative immunohistochemical staining. The results showed as follows:1. None of EAE rats on days 4,6 and 8 p.i. showed clinical signs whichbecame apparent on day 10 p.i.(2.33±0.76; n=6). On days 12 and 14 p.i.

检测p.i。第4天、6天、8天、10天、12天、14天、16天、18天、20天血清和CSF中ALB含量，其CSF／S ALB比值作为评价BBB损害的指标；同时段取动物脑、脊髓、胸腺和腹股沟淋巴结制成石蜡切片行HE染色和ICAM-1半定量免疫组化分析，结果显示如下： 1、EAE大鼠p.i.4-8天无任何临床表现；p.i.10天症状开始明显，症状评分为2.33±0.76(n=6)；p.i.12-14天为发病高峰期，症状评分为3.75±0.54(n=12)，病情由最初的活动减少，体重减轻逐渐发展为肢体无力、瘫痪，共济失调，甚至濒死状态；p.i.16天大部分动物症状开始缓解，评分为2.08±0.66(n=6)；p.i.20天疾病症状完全消失。
