Study on the Relationship between Contamination Distribution and Sampling Density Xiao-Song Sun1, An-Ping Liu2,a, Xiao-Nan Sun2, Wei-Guo Tang3 and Jian-Ming Sun2 1College of Mechanical Engineering, Chongqing University, Chongqing 400030, China 2Institute of Environmental Physics, Chongqing University, Chongqing 400030, China 3 Chongqing YURONG Water Engineering Co.Ltd, Chongqing 402460,China aliuanping@cqu.edu.cn Key words: System layout method, Contamination distribution, Sampling density Abstract.
For the horizontal layout of sampling points in the site environmental monitoring, common layout methods of monitoring points include simple random layout,professional judgement layout, partition layout and system layout method etc.
Table1 Common layout methods and their applicable conditions Layout method Applicable conditions simple random layout Well-distributed contaminated sites professional judgement layout Sites with definite potential-contaminants partition layout Sites with known contaminated distribution condition but inhomogeneous contaminated distribution system layout method All kinds of sites, especially the sites with unknown or large-range contaminated distribution.

However, it is hard to make daily maintenance for the dam in practical engineering applications, Becaese the obtained data curve only fit for professionals to analys according to the measured environment, and then guide officers to take the right measures based on the data analysis.

Introduction Over the past decade, researchers work from different professional Angle experimental research micromechanics，achieved fruitful results.
Significance of the study In recent years, researchers work from different professional angle experimental research micromechanics.
Specimen production Table.1 Table cylinder specimen material Fixed ratio of the material parameters Ratio (g) Barite powder Powdered iron Plaster Water Parameter value 1249 250 100 420 Burst mode analysis From the formal point of view of the rupture surface can be divided into three situations: there is only a surface rupture; only shear plane exists; tensile-shear conditions co-exist

HAZOP procedure is effective in identifying hazards by professional group and is well accepted by the petrochemical industry[2].
A professional group was established for performing a HAZOP study on the plant to identify hazards of the process.
For example, choking effect of the two order chock valves and heating coil are main causes of hydrate formation in the water jacket furnace node, it has been well known for experienced operator, but operator and adviser have no idea of what valve opening and coil heat efficiency should be.

Some units are often the reasons for the lack of mountains in the professional and technical personnel, etc. and not on time.
(2)On the excessive pursuit of low-power components, under conditions of high humidity mines, methane, water vapor in the combustion element surface is easy to condense on the surface of components, reducing component life; (3)Poor ability to prevent poisoning; (4)The technological level of the carrier catalytic elements used by methane sensors is below standard which finally result in poor performance.
Solutions 3.1 Strengthen the Site Management and Maintenance Standard While national and provincial, and municipal administrations mandatory requirement of coal major, medium and small coal mines with high gas or gas outburst mine monitoring and control system must be equipped and increased the mine production safety management efforts, but some places state-owned mines, especially small township coal mines, due to the lack of professional and technical people Members which have not properly use the equipment and maintenance system, causing the system does not have the function of maintenance terminal device to become the bottleneck of the entire system, even a sensor connected with the system does not be adjusted.

This system can be used with the existing professional wire-cutting equipment.
Extract water in surface.
After being filtered, rinse solid with water till PH neutral.

Design and Implementation of Information Management System Based on Cloud Computing Mode CHEN MiaoXuan 1, a 1 Wuxi Professional college of science and technology, Wuxi 214028, China a ChenMiaoXuanwx@yeah.net Keywords: Cloud Computing; Information Management System; Google App Engine Abstract.
Like water without household now dig wells, but unified waterworks water supply; use electricity don't have to buy generator, but power plant centralized power supply.
This means that the cloud computing makes computing power into commodity like water, electricity and gas, can be in the market for circulation.
Water and electricity is through the water pipes, wire transfer, and computing power is transferred over the network. [1] The thought of cloud computing to bring computing together let the rage PC no longer have the beautiful scenery of the past, because it takes only a machine connected to the Internet browser to fulfill all customer requirements, even some super computing tasks. 1.2 Cloud computing architecture Cloud services are divided into three types, respectively IaaS, PaaS, SaaS, constitute a cloud computing architecture, as shown in figure 1.

Three dimensional digital image correlation method is to place two industrial cameras in front of the samples to be tested, adjust them at the same level with a professional tripod, and calculate the front and back coordinates of the points to be tested through the professional algorithm of the computer.
There are many ways to make the speckle pattern: water transfer printing, UV plate printing, painting, etc.
The change of strain field on the surface of the object to be tested is captured by professional industrial camera. 2.

He acclaimed Qingdao in a letter to his friend, "Green mountains and water, blue sea and sky, top of China ".
To protect and develop the celebrities’ former residences by specialized scholars.The positive participation of scholars would ensure the protection without severe mistakes and avoid the unnecessary damages due to lack of professional knowledge of protection and utilization in government.
The protection process can not be simply defined as government action, and exclude the professionals from decision-making, but listen more to the experts in culture, history, architecture and other aspects to enable them truly devoted into the protection work.

A solution of acetic acid was used (4% volume) in water.
Thus, a professional of dental prostheses must be aware to the material mechanical characteristics because the sintering parameters are strongly influenced by them.
Thus, the professionals who works the aesthetic effect of zirconia in dental prostheses must take into account the conditions where this ceramic will perform its roles, considering the prostheses geometry, beyond the mechanical efforts to which it will be submitted.
