ABSTRACT The ionic strength of mobile phase can significantly affect the peak shape of ionogenic compounds such as antibiotics in reversedphase high performance liquid chromatography. The influence may be attributed to overloading of ionogenic analytes in lower ionic strength mobile phase.

在反相高效液相色谱过程中，流动相的离子强度可显著影响可解离的化合物如抗生素的色谱峰形，原因在于流动相的离子强度较低时，色谱填料的固定相易于过载，使离子化的化合物的色谱峰形呈典型的过载特征――峰形接近直角三角形。

Abstract］ objective to explore the occupational stress status in head nurse.methods sixty one head nurses completed the osi-r.results there was occupational stress in head nurse.there was significant difference of occupational stress among head nurse with different age,educational background,job title,time to hold a post.conclusion head nurse is matrical leader,who plays important role.each medical treatment organization should be as far as possible to reduce occupational stress and relieve the occupational stress,in order to protect their spirit and body health.

职业紧张或称职业应激、工作紧张，一般是指在某种职业条件下，客观需求与主观反应之间失衡而出现的生理变化和心理压力，以及由于不能满足需求而引起相应的功能性紊乱［1］。21世纪，临床护理工作面临着新的挑战和更大的压力。护士长作为医院管理中最基层的领导者和组织者之一，扮演着重要的角色，护理管理水平的高低直接影响到医院管理质量的优劣和医疗水平。因此，了解护士长职业紧张现状，积极提出预防对策，以提高护理管理水平。

Then, according to phase space reconstruct technique from one-dimensional and multi-dimensional time series, the quantitative criterion and rule of system chaos which combine neural network, analyses, computations and sort are conducted on EEG signals of five kinds of human consciousness activities. The author finds that statistic results of the determinism computation in time series indicate that chaos characteristic may lie in human consciousness activities, and central tendency measure is consistent with phase graph, so it may become one division way of attractor; approximate entropy of different subjects exists discrepancy; correlation dimension and Lyapunov exponent of different consciousness activities indicate that attractors of human activities are all fractional; nonlinear quantitative criterion and rule, which unites neural network, can distinguish different styles of consciousness activity in principle, and the result of sortation takes on that consciousness activity type of arithmetic is distinguished more easily than that of abstract.

采用一维与多维时间序列相空间重构技术和系统混沌的定量判据准则，结合神经网络，对五种思维作业方式的脑电信号进行了分析、计算与分类，发现确定性计算的统计结果表明人类的意识活动中可能蕴含混沌特性，中心趋向测量(Central Tendency Measure，CTM)与相图吻合较好，可作为EEG吸引子的区分方法之一；功率谱分析反映出单个受试者的各种意识形态的差异很小，但是不同意识活动谱中的活跃频段还是略有差异的；个体之间的近似熵存在差异，同种状态下近似熵大的人可能具有更好的创新性；关联维数和Lyapunov指数的计算结果表明大脑的运动落在具有分维的奇怪吸引子上；非线性量化方法与神经网络相结合，可对人脑思维活动进行较好的分类，并且从分类结果来看数理计算类思维活动较抽象类思维活动有着更好的区分度。
