In practice, most of the neural network model using BP neural network and its change form is widely used in function approximation, data compression and pattern recognition etc [6].
The deviation between the network output value Y and the expected output value t, by adjusting the input nodes and hidden layer node connection strength value of and the hidden layer node and output node coupling strengthand threshold, the error reduction along the gradient direction, after repeated training, to determine the network parameters corresponding to the minimum error (weight and threshold), train terminates.
Select the part of actual production data input into the model.

The dimension reduction method of principal component analysis is adopted in this paper to analyze the effect of the related major parameters on the boiler efficiency.
In the discussion and study of the major parameters, combination of theoretical formula derivation and the actual production data makes the mutual corroboration of theory and practice, which leads to the more accurate results in this paper. 1.
The following is the influence of the flue gas temperature on the boiler efficiency of the 300MW boiler in general: Figure 1 The influence of the flue gas temperature on the boiler efficiency According to the data in the above table, we draw the line graph to view the relationship between boiler efficiency and flue gas temperature by using MATLAB.

(6) The conventional PID controller, Gc, is then identified using inverse identification method from noise free simulation data generated using a SOPTD approximation of the plant model and the invertible part of the model as given by (6), and adjusted by tuning parameter which is described below.
The identification data is generated by simulation using (6).

Then we induct the nodal data to the Matlab and draw up the curve, as is shown in Fig. 3 and Fig. 4.
Then we induct the nodal data to the Matlab and draw up the curve, as is shown in Fig. 6 and Fig. 7.
Therefore it has obtained large scale reduction.

It also leads to the reduction of primary energy source power of the internal combustion engine (ICE) and its load cycle equalization.
Estimation of BES capacity based on experimental data Energy source power and BES capacity are primary thought to be the main hybrid powertrain parameters.
An estimation of BES energy level for HEV moving in the same cycle during one trip was carried out when using the received data.

The experimental data and change rule were analysed (Figure 2).
The experimental data and change rule were analyzed (Figure 3).
At the beginning of reaction, with the concentration of potassium permanganate increasing, the speed of oxidation reduction reaction was accelerated, because of the strong oxidation of potassium permanganate in the condition of strong acid.

Introduction Vibration reduction and isolation technology provide a new way for bridge antiseismic and has been used in railway bridge engineering in China, but there still are many problems not solved in calculation analysis and design theory.
Kyu-Sik Park et al. solved the contradiction between the reduction of the maximum forces and the increment of the beam displacement by introducing the weight coefficients [3].
According to the test datum of the lead core rubber bearings from China Academy of Railway Science, and [7]; =the relative displacement between beam and top of the pier at different time of the seismic excitation history; =the acceptable value of relative displacement between beam and top of the pier.
In order to acquire the reasonable parameters which meet both good vibration reduction effect and running safety requirement of vehicle, the dynamic optimization of the LRB dynamic controlling parameters is necessary and meaningful to the seismic isolation design for bridges

The model is based on 4H-SiC physical and material properties and is validated by high temperature 4H-SiC lateral JFET data, fabricated and characterised by our group at Newcastle University.
Next, the validation of these model parameters using the data from 4H-SiC lateral JFET is presented.
EgT=Eg0-α T2T+β (1) High doping concentration causes a reduction in the bandgap of the semiconductor.
This data is illustrated in Fig. 1(a), along with the best fit of the Aurora doping dependent mobility model.
Overall, the simulated results show excellent agreement with the measured data; highlighting precise calculation of threshold voltage and drain saturation currents.

Based on the structural geology, sedimentology, palaeontology and geochemistry, the sedimentary facies and evolution patterns are developed in Songnan area from the studies of seismic data, cores, well logs, palaeontology and geochemistry.
With the increasing number of wells and improved quality of seismic data, oil and gas resources have been found in fault basins in recent years[8-9].
On the basis of former researches and according to the interpretation of well logging, lithology and seismic data, this paper studies the sedimentary evolution of the fault depressions in Songnan area in detail combined with paleontological data and holds that the buried depth of the study area is great and the sediment strata are thick, which have good source-reservoir-cap assemblage. 1 Regional geological conditions Songnan area is located in the east of Inner Mongolia Autonomous Region, transversely placed at the crossing of Liaoning province, Jilin province and Inner Mongolia Autonomous Region.
Shahai Formation also contains sporo-pollen, ostracoda fossils and plant-derived fragments. 3.4 The sedimentary period of Fuxin Formation The bounding faults activity decreased at this sedimentary period, leading to the reduction in water depth and slope gradient at the edge of the basin.
