According to the monitoring datas of Beizhuang in Miyun county.
Each index of index system data were shown in table 1.
Index datas use the monitoring datas from Beijing and BeiZhuang during 2002-2007.
The computation formulas were listed as follows: () (1) (2) Among them: ——sample standard deviation of index section data of item index ——sample mean of index section data of item index ——variably coefficient ——the weight of item index Every year’s indexes were made to be a guideline in section data in the calculation.
This showed that the slightly reduction of ecological efficiency index in 2005 was due to abnormal climate, that did not affect the rising trend of ecological benefit during 2002-2007

Such a choice can be envisaged because the residual Pu is of very poor quality following the large reduction of the fissile isotopes (239Pu and 241Pu).
The reduction of the Pu inventory has to be performed in an economical, ecological, safe, proliferation resistant and sustainable manner.
First, the reduction in actinide inventory helps to achieve this goal.

Sampling and Data Analysis Through the course of the experiment, 20 fish were taken from each pond monthly and their length and weight were measured to assess the growth.
The logistic model was fitted to fish growth data with non-linear least squares (nl-LS) with iterations by means of Marquardt’s algorithm, using MATLAB v. 7.4.0.287 (MathWorks Inc., Novi, MI; http://www.mathworks.com).
The wetland reduction efficiency of 5-day biochemical oxygen demand (BOD5) and chemical oxygen demand (CODCr) were 70.4% and 49.2% respectively.
The overall reduction efficiency of total ammonium nitrogen (TAN), nitrite nitrogen (NO2--N) and nitrate nitrogen (NO3--N) were 53.7%, 64.7% and 5.6% respectively.
The wetland reduction efficiency of TP and IP were 20% and 33% respectively.

According to the data analysis of steel product supply and demand in Taiwan, the annual waste acid output in Taiwan is more than 1 million tons.
Most existing methods or processes have poor hydrochloric acid reduction effect, or the byproducts have low economic benefit.
Integration of US Patent No. 5562828[5] and foreign and domestic patent and journal data[6 - 14].
Reaction time: ORP (oxidation-reduction potential) detection, controlled within 2~3.5 hours, to form ferrite recycled product (Fe3O4).
Reaction time: ORP (oxidation-reduction potential) detection, 3~5 hours reaction is required to form goethite process powder (γ-FeOOH). 5.

The following part of this article is the discussion of the system data flow and module design.
Fig. 4 Date flow of material management subsystem System Design.Business processes discussed before have provided officers what to do and when to do; it is the carrier of data, while data is the core of it.
Actually, business processes mean data flow, from one point to another.
The overall data flow of our system is shown in Fig. 4.
Material information module manages the data of material, semi-product and product, which can be dynamic display in our system.

Measurement setup During the whole experiment measurement data from all the sensors applied to the construction were constantly collected, with predefined intervals, using distributed network data acquisition system.
Magnetic field and earth field acceleration data were sampled with a sampling frequency of 2 Hz.
Sensors were transmitted measured data over CAN network to the cRIO controller (NI 9853 module).
Sampled data were send from the computer to the database of the system over TCP/IP network.
There were no significant difference of the standard deviation of the measured displacement between the data obtained using reference camera and the camera the data computed after rectification.

The approaches such as the carrier number and the Hooge mobility fluctuations used for the analysis of the noise sources are illustrated through experimental data obtained on advanced CMOS generations.
The approaches such as the carrier number (CNF) and the Hooge mobility (HMF) fluctuations used for the analysis of noise sources will be presented and illustrated through experimental data obtained on advanced CMOS generations.
The value of a is about 10 times lower than for pure SiO2 gate dielectric, which could be due to the deeper trap location, resulting in a more remote character of the Coulomb scattering and, in turn, a reduction of a.

A proposal is made to establish a corresponding database based on simulation and production data.
Due to the adoption of conical mandrel, the pipe can reach up to 25% diameter reduction rate in the cold rolling process. 3.
This is an iterative process, through the accumulation of test data, the relevant simulation – test database can be established.
