Based on the processed images , we can do the further computerized quantitative measure of parameters including area , perimeter , integrated optical density , average diameter , shape factor , number of bifurcation and end points , etc . our self - developed and localized system has a reliable property and a high ratio of performance and cost proved by our experiment 对感兴趣区域内的目标自动测量参数，如：面积、周长、综合光密度、平均直径、形状因子、三叉点、端点等。与其它类似系统相比，本系统具有性能稳定，开发成本低，技术性能价格比高的优点，成为国内医务人员易于掌握与使用的医学应用系统。
Simultaneously , enhancement of the cross section must has had been played an important role in astrophysical nuclear process . we investigate the s - process of nucleosynthesis of heavy element of astrophysics and give a group of analytic solutions for the s - process . to check up the analytic solutions , we calculate the n distributing of the heavy element of s - process in solar system and the result is good agreement with astronomic measurement 我们研究了天体重元素核合成的s ?过程，给出了s ?过程网络方程的一个解析解，作为对本文解析解的检验，我们计算了太阳系的s ?过程重元素丰度的n分布，计算结果与天文观测符合的较好；另外，我们还计算了s ?过程的典型分叉点~ ( 85 ) kr处各个核素的丰度变化，与已有的结果符合的较好。
Chapter five took advantage of synergetics theory to established an synergetic transportation model of logistics enterprise system in transportation network . control parameter threshold value equation was derived and we combined data of logistics enterprise ' s instance to writer a program to calculate numerical val 第五章应用协同学自组织临界理论构建物流企业系统在物流网络区中的协同运输模型，推出控制参量临界值公式，然后结合实例分析得出的数据，编写程序并计算出分叉点控制参量kc的数值，求出几个主要的序参量之间的对应关系，为物流运输调运决策提供依据。
The calculation of ttc involves network limitations due to thermal and voltage stability limits . network limitations are to be calculation not only for the current operating but also for a worse case that could occur due to a set of contingency cases , which require huge amount of computation 本文以连续潮流技术为基础，提出了考虑各种约束条件的电力系统区域间最大输电能力的分析与计算，考虑了电力系统运行中鞍型分叉点造成的静态电压稳定性约束条件等的计算。
Abstract : in this paper , the feature of time - bifurcation for plate - beam stability is studied by mechanics model of plate - beam structure of rock in compression . the instability time of plate - beam is dependent on the rock material feature . delay bulking occurs under some load . the formula of time - bifurcation is given . the mechanisms of roadway floor heave and delay rockburst are preliminarity discussed 文摘:采用岩石板裂梁的纵向受压的力学模型，考虑深部岩石的流变性，分析了板梁稳定性的时间分叉特性.板梁失稳与岩体的流变性质密切相关，在一定载荷下，经历一段时间后会发生延迟失稳，给出了时间分叉点的计算式.并对深部矿井延迟性岩爆发生机制进行了初步分析
