On the basis of measuring tetracycline front teeth L, a, b value range (L value 42.33-77.00, a value 0.69-9.60, b value 2.67-31.50) [8] by the Chinese and the selected four group data from the measuring L, a, b values collected from the clinical tetracycline tooth, utilize the professional software to create colorful background, then print out and plastic seal as tetracycline abutment tooth.
All specimens were ultrasonically cleaned in distilled water for 10 minutes and dried to be free of dirt and grease (Kang Jie, Dongguan, ultrasonic equipment company, Ltd).
Rinse with tap water for 30 seconds before place in the ultrasonic vibrator to clean for 10 minutes with ultrasonic.
According to the measured range of the Chinese tetracycline tooth-colored by DanPing Ruan [4], this experiment utilized the professional software to create unified tetracycline abutment tooth background with the provided unified L, a, b values, thus ensured the homogeneity of the experiment.

Part state of simulation equipment can be observed by naked eye(such as component’s surface wear-out), part can be directly known the information from equipment itself ,such as instrument, indicator light, the other big part of it must be got with the tools of professional test.
In one word, No matter naked eyes or professional test tools, these feedback behavior, are the performance of the simulation equipment in some conditions, when the trainees operate simulation equipment or use a tool detection simulation equipment,.
According to these, it can produce a motion evolution image, thus, in the reality simulation, particle system are always used to indicate flame, water-flow, storm ,blizzard, cyclone, fountain and other phenomenon.

Jets of water washed the paydirt and it goes through the grizzly bar and through the palong (sluice box).
The paydirt hopper where the material is washed with powerful jet of water D C The shaking table is used to extract the gold from the material recovered from the palong.
However, AMML and PMSB need to raise some extra capital to embark on a proper exploration program and to engage appropriate professionals to make this endeavour a success [4].

Similarly, Qinba region is rich of water resources, in order to ensure the “the river water to Beijing”, it need to sacrifice the local water resources advantages, and make sacrifices in economic field.
And industrial trudging, economic hindered seriously affected the enthusiasm and self-consciousness of the local government and the masses who participate in soil and water conservation.
In recent years, the country vigorously foster the modern agricultural development, expanse the modern agricultural zone, at the same time it is a requirement that local farmers need master more professional technology and management idea.
Clearing the benefits related parties, improving the government management function, trying “the paid transfer of water rights”, establishing “bank of water” and other market-oriented way, makingwater rights deal by the market mechanism, establishing interest compensation model of water source.

Corrosion due to water and other factors[1,4,5,6,7].
The leading action of water in the process of corrosion includes the following[1,4,5,6,7]: 1)Water is the necessary and sufficient condition of electrochemical corrosion.
Hydrogen sulfide and carbon dioxide have high solubility in water.
In a gas-water diphase sour system, water is highly harmful. 3) The Cl- in formation water may generate serious corrosion of metal.

Because of involving different professions, administer departments and much contents, it results in complicated professional technical integration and coordination management, it is necessary to bring into effect green building for the sake of goal of progress, quality and cost, green technology functions, etc.
The actual effect of green building implemented is displayed by data of operation, management and third-party testing, which involve the building’s power consumption, water consumption, utilization index of non-traditional water etc.
The appropriate management systems and manual are set up, which are energy conservation, water management, supplies management, green management system to develop energy, water and resource conservation-related regulations and the use of appropriate incentives.
Fig.1 The simple solar hot water bottle Operation Label Phase.
For instance, we set up a simple solar hot-water bottle for bath water of the employees with hot water in the course of construction, shown in fig.1.

My perceptions of the biohydrometallurgical field span four decades and stem from being a professional microbiologist conducting academic research and research for process development and applications.
The rock material was irrigated with mine tailings water, containing 10 5 A. ferrooxidans/mL the mine water also served as an inoculum.
The source of these moderate thermophiles was thought to be the mine water used for irrigation.
Some lessons that a professional microbiologist learns from process development for the mining industries are: • The development process requires time -- years to a decade or more can elapse from process inception to process implementation

TOC concentration was monitored by a TOC analyzer (Model ET1020A). pH value was detected via a Professional Meter (Model PP–50).

In recognition of our local industries’ need for professional engineers with engineering practical ability, real projects based on industry application provide a means to teach students many of the skills they need to succeed after graduation [1-2] .Students can see trees of application in process control using PLCs as well as a whole forest by completing the project step by step.
This kind of design experience may be changed to design other similar control system used in other industry field such as water process plant.
High pressure water descaling system has two basic running states: unloading with low pressure and descaling with high pressure.
System start with low pressure unloading state, a pump operate at low frequency , the unloading valve is open, water from high pressure pump returns to the high water tank through the unloading valve and thus no-load unloading is realized.
The water is returned to the tank through the unloading valve.

(5) Water reducing agent The water reducing rate is 30%, and it meets the requirements of “Concrete Admixture” (GB8076-2008) and “Polycarboxylic Water Reducing Agent” (JG/T223-2007)
(7) Water The water meets the criterion of “Standard of Water for Concrete” (JGJ63-2006).
Water-binder ratio at 0.31 to 0.36 is the best, and the dosage of water reducing agent is about 2.8%.
So, when using water and cementing material quantity stably, the concrete becomes very sticky, and the fluidity becomes bad.
