Crosstalk_f
该程序用于计算n根平行导线间的串扰,程序结构及说明见程序内。源可以是单频的或脉冲的(这里给出的是频域的)。频率、波形、线长、电源及负载阻抗均可在用MATLAB编写的语句中方便地修改。但必须输入导线系统每单位长度的电感、电容矩阵。(The procedure used to calculate n root of crosstalk between parallel wires, program structure and description of process. Source can be single frequency or pulse (here is given by the frequency domain). Frequency, waveform, the line is long, power and load impedance can be found in the use of MATLAB statements prepared easily modified. However, the system must enter a wire per unit length inductance, capacitance matrix.)

本文区别于其他传统的人口预测模型,深入分析了当前中国人口的基本情况,以及
最近几年中国人口的发展情况与趋势,针对中国人口基数大、男女比例不协调、乡村人
口城镇化加速、人口老龄化日益严重等显著特点,在各年龄段生育率短期内保持不变的
假设下,建立基本的人口转移回归模型,用于模拟预测短期内中国各类人口数量发展变
化。该模型预测结果显示,中国人口在未来十几年内增长一定幅度后开始下降;与此同
时,人口老龄化、男女比例失调等问题日益严重。该模型短期内的预测效果比较好。
为了使中国将来的人口发展健康、平衡,综合考虑中国以及欧洲一些发达国家和亚
洲一些实行计划生育较早的国家以前以及当前的一些情况,本文提出了修改计划生育政
策的建议。面对日益严重的老龄化现象,我们提出生育率应该参考老龄人口比例这一新
思想,并建立生育率与老龄人口比例的关系模型,用于长期人口的预测。预测结果显示
中国总人口在短期内持续上升,在2025 年到2040 年之间基本保持在14.6 亿的最大值,
然后开始缓慢下降。
两个模型的结果均显示,中国将会面临严重的老龄化和男女比例不协调两个问题。
最后我们提出了适当措施以缓和这两个问题带来的影响。(This is different from other traditional population projection model, in-depth analysis of the current basic situation of China s population, and
In recent years the development of China s population and the trend for China s huge population, gender disharmony, rural people
I accelerated urbanization, the growing aging population and other significant features in the short term fertility of all ages remain unchanged
Assumption, the establishment of basic population transfer regression model, to simulate and predict the short term development of China s various types of population change
Of. The predicted results show that China s population growth in the next decade began to decrease after a certain extent and the same
When an aging population, gender imbalance and other growing problem. The model predicted the short-term results were better.
To make the development of China s future population health, balance, considering China and some developed countries in Europe and A)
