Recently, due to the reduction of oil and the deterioration of environment, people raised higher request for fuel economy and emissions, hybrid vehicle developed rapidly in most countries because of its low fuel consumption and emissions.
The simulation data indicates: PHB can improve the fuel economy and emission performance effectively with guaranteeing a good dynamic performance of bus.

The reduction of vehicle hardware and the entire system weight are not the only motivational factors contributing to the development of a Brake-by-Wire system.
A major deficiency of this solution is generated by structural planetary reduction gear, which by the component of it requires multiple tolerances for gearing and rolling.
The reduction of vehicle hardware and simplified control of various functions, offered in cooperation with the braking system, allow fast setup software platform.
Most changes in the software and data aquisition can be implemented and tested without having test drives.
A computer data acquisition board serves as online measurement system.

The reduction in weight of the spring will increase the riding quality and also increase the fuel efficiency.
The reduction in unsprung weight can improve the riding quality and increase fuel efficiency significantly.
Since composite material has a high elastic strain energy storage capacity, it is possible to use composite material to replace the conventional multi leaf steel spring in order to achieve weight reduction without any reduction of the load carrying capacity.

The hardening of the materials means a reduction of dislocation motion which is known as the main mechanism of damping in magnesium alloys [4].
From this point of view a reduction of the damping is expected.
For the calculation of δ from relaxation data a simplified equation can be used [9], )( )ln(d d 2 2 E E t ∆ ≈ π δ
This approach is able to represent the measured data but does not consider grain boundary sliding which should overlap dislocation motion and contribute to total damping.
The forming process led to a significant reduction of grain size accompanied by an increase of the strength (HallPetch relationship).

Data transmission: upon the data acquisition and storage, the quantity of data is small, so they can be transmitted into the client unit by directly using the form of command transmission.
Among the energy saving and consumption reduction measures, electric energy saving is the most convenient with the lowest cost.
b) Wrote and debugged the data acquisition and data transmission software.
It is found in the practical use and testing that the system can timely, accurately and perfectly collect data, operate reliably and remain open and flexible in the aspect of data acquisition and transmission as well as data process and storage.
The electricity-use monitoring data platform established with this system can obtain the energy consumption state of the monitoring equipment in real time, master the data resources in the use of electricity and provide rich data materials for energy inspection and adequate data supports for energy saving and consumption reduction.

The strain gauges, load cells and LVDTs were connected to the same data logger and the results recorded automatically at each load step.
Comparison of predictions of formula with experimental data.
The figures show that not only the predicted failure modes of prestressed beams are well agree with the actual failure modes, but also the predicted nominal moments are very close to the experimental data.
Because the experimental data is very limited and experimental beams are all over-reinforced prestressed sections, the equations of ideally reinforced section are not confirmed.
(e) The predicted nominal moments are very close to the experimental data.

The data tier comprised of social composition data, economic data, water resource data, eco-environmental data etc., and they are divided into two major categories - parameter and variable.
These data will be collated and transmitted to the constraint tier and objective tier.
There are mainly 74 input data and 44 output data in the model.
The flow data from 1956 to 2005 reflect that of long term average flow and the data from 1980 to 2005 reflect the conditions of relatively low flow in recent years.
Our future work will focus on strengthening the use of remote sensing of ET data.

A mechanical behavior of solid waste during foundation pit excavation is discussed on the base of the in-situ monitoring results of earth pressure and field measured data in solid waste.
Lacking of data about foundation pit excavation in old landfill site, the collection of in-situ monitoring data is very necessary.

However, most of the researches were based on the data of a country.
We used the estimated data in our study.
The data of tillage is calculated from areas of crop sown.
The data of agricultural irrigation is calculated from areas of actual irrigation in Sichuan province.
The data of the annual GDP per capita, the total gross value of the agriculture sector, planting production, data of population come from “Sichuan Statistical Yearbook (2012)”.
