For the limitations of traditional algorithms that can not be reasonably accurately predict the traffic, we have adopted BP neural network and curvilinear regression algorithms. First, we use BP neural network to train on historical data and then use the curve of regression to predict various factors, and then forecast data into the trained BP neural network which has been trained well, you can get future traffic forecasts.

针对以上传统算法的局限性，采用BP神经网络与曲线回归耦合算法，用BP神经网络对历史数据训练，利用曲线回归对各因素待测年份之值预测，将各因素的预测值带入已训练好的BP神经网络中，即可得到未来交通量的预测值。

"This study raises the possibility that androgen replacement therapy might lower the risk for Alzheimer's, but this is far from proen," says Sam Gandy, MD, PhD, chair of the Alzheimer's Association's Medical and Scientific Adisory Council and director of the Farber Institute for Neurosciences at Thomas Jefferson Uniersity."Because testosterone is rapidly conerted to estrogen after entry into neurons, the new data are logical, and they doetail well with historical data."

"这项研究增加了雄激素补充疗法降低阿尔次海默危险性的可能，但是里真正的证实路还很长，"阿尔次海默医学协会和科学咨询委员会的**，Thomas Jefferson大学的神经病学Farber协会的主任，医学博士，公共卫生学博士Sam Gandy说，"因为雄激素在进入神经元后迅速降解为雌激素，新的研究资料还有局限性，然而他们的研究结果与历史上研究的结果很吻合。"

During this process, the spherical polar coordinate transformation and the circle polar coordinate transformation are used to carry on the pretreatment for the historical data about investment ratio and investment accumulation rate of the three industrial sections, and the consequent data also be simulated by statistical software-SPSS12.0; Finally, sensitivity analysis according to investment ratio and the fixed assets investment accumulation rate of the three industrial sections are made and a better resource distribution plan for the three industrial sections also be given.

在预测的过程中，利用球面极坐标变换和圆极坐标变换分别对三次产业投资比例和积累率的历史数据进行预处理后，再利用统计软件SPSS 12.0进行拟合；最后，利用固定资产投资的积累率和三次产业的固定资产投资比例进行灵敏度分析，提出了一个较好的三次产业经济的资源分配方案。

You can then measure the error using a statistical measurement to describe both how well a pattern reproduces historical data and to estimate how accurately it forecasts the data into the future.

你可以利用统计度量的方法对误差进行度量，从而对历史数据的结构进行复制，对未来预测数据的准确性进行描述。

The automation system is required to control the overall situation of the whole electrified wire netting, monitor and control the condition of device, and fulfill four remote functions, that is, telemeter, communication, remote adjustment, and remote control .In addition, the system should record the historical data, form tables, analyze the data as well.

随着我国电力系统网络大规模改造以及大型工矿企业的升级，变电站对自动化程度的要求越来越高，要求能够综合监控整个电网的运行情况，监控一次设备的状况，实现四种功能（遥测、遥信、遥调、遥控），以及历史记录、报表、事故分析等等。

Based on field investigation and historical data analyzing, the characteristics and causes of flood disasters of Qinba Mountain area were discussed in this paper. Take the harnessed Watershed and unharnessed Watershed as comparative study objects, through analzing the two typical watershed land using and rainfall-runoff dynamic data, combinating the in-situ soil infiltration field testing, a rainfall-runoff model of small watershed which was appropriate to Qinba Mountain areas was built based on improving the SCS model. And then the influence of soil and water conservation measures on the flood processes was analysed.

本文通过野外调查与历史调查资料，阐述了秦巴山地区洪水灾害的特点及成因，以治理流域与未治理流域为对比研究对象，通过对两条典型流域的土地利用状况分析，结合土壤入渗原位测试，充分利用降雨、径流动态观测资料，以SCS模型模拟降雨径流为重点，建立适合于秦巴山地区小流域的降雨径流计算模型，分析水土保持措施对于洪水的作用过程。
