Systemic studies environment temperature how to influence construction control, finds out linear regularity and function formula of the arch rib, selects optimal closure time, then fully meets requirements of closure precision and linear. By testing a lot of data on temperature and strain and adopting least squares collocation, this dissertation deduces the strain calculate formula that is amended by joining temperature factor, then improves accuracy of stresses testing data.

系统地研究外界温度变化对施工监控的影响，找出了拱肋变化的线性规律和函数式，选择出最佳合龙时机，保证了拱肋的合龙精度和线形要求；测试了大量温度与应力对应关系的实验数据，采用最小二乘拟合推估法，推导出温度修正后的应变计算公式，从而提高了应力测试数据的准确性。

The former hypothesis is mainly based on mathematical linear extrapolation from effects observed by high doses. This notion advocates the linear assumption of radiation risk and that there is no lower limit to the amount of radiation that causes short- or long-term damage. The latter is the countervailing hypothesis-radiation hormesis.

前者主要依据高辐射剂量效应的观察，用数学线性补插法来求低剂量之效应，主张：辐射剂量会造成短或长期的伤害，且无低限值的；后者的证明来自於广泛的流行病学观察和实验研究的科学资料，这些证明指出辐射对人的伤害有确定的阀值剂量。

And the reasonable proposal for the construction the region electrical power system was put forwardThe power load forecast is the basis of the power system planning.With the actual planning of regional development,uses a scientific and effective load forecasting methods forecast plans the local load electric quantity,is an important work to the regional power system planning.This dissertation uses the BP algorithm, proposed a double hidden layer structure artificial neural network to the forecast ultra-short-term power system load.After the simulation with the actual data,the method which this dissertation proposed compared to the traditional linear extrapolation Prediction method average absolute percent error of 2.5 percentage points,ten minute load forecasts achieve the average absolute percentage error are smaller than 2.5%accuracy.
