Based on present situation of chinese ecology community construction, some strategies are presented, incuding that the first is urban planning at macro-level; the second is spatial plan, transportation system, service facilities and green space system at medium measure; the third is water environment plan, energy plan, architectural design from at micro level; the fourth is community housing structure and public participation from social policies.
·Professionals—the understanding of low-carbon ecological community incompletely A lot of designers still confine the understanding of low-carbon ecological community to the engineering aspect, for example, source, energy, applications for environmental protection technology, and then it cause to one-sided lay too much stress on constructions of physical environments .
·Water environment program There should use rainwater collection technology, wastewater renovation, man-made wetland ecosystem and porous pavement.

Introduction Supercritical water (SCW) is the water which above the critical point of pure water (374℃ and 22.1MPa) and supercritical water oxidation (SCWO) has been proven as a clean and high-efficiency technique for destroying the pollutants.
Complicated corrosion behaviors would occur when the test condition is the real corrosion condition of waste water.
The characteristics of pesticide manufacturing waste water are shown in table 1.
The chemical oxygen demand (COD), ammonium (NH4+) and Cl- concentrations are determined by a Merck NOVA60 multi-parameter water analyzer, with an accuracy of ±2%.
The pH was analyzed by a Sartorius Professional Meter PP-50.

Nursing Care 2.1 the preoperative nursing care 2.1.1 preoperative assessment through set up and after division within the professional training of preoperative nursing quality-control team insight patient's condition and the drug.
teach patients to cooperate with angiography while breathing methods: deep breath, exhale; Postoperative patients need to keep force position again, therefore, preoperative patients with 1 ~ 2 guidance practice in bed for drinking, eating, and defecate hip hypothesis and roll over method such as training; Instruct patients to eat more vegetables and fruit, avoid eating sweet soup, egg, prevent constipation and bowel bilges gas 2.1.4 Routine care to provide a quiet and comfortable environment, ensure sufficient sleep; Preoperative 3 d to give oral enteric aspirin in patients with 300 mg/d, wave d 75 mg/d anticoagulation, preoperative 2 h on the left side of the body to create venous indwelling needle, nim to trace pump pumping jersey (3 ml/h), and to alleviate cerebral vasospasm, preventing platelet deposition in the atheromatous plaque, reduce intraoperative blood clots fall off; The preoperative 1 d guild privates and bilateral inguinal clean the skin for skin, preoperative 6 h fast water
According to the speed of blood pressure regulation, it needs to control the blood pressure in basic level. 2.2.4 Some patients can appear reactions such as headaches, dizziness, nausea, vomiting, the person that weigh can appear arrhythmia, shock, collapse, cyanosis, laryngeal mucosa edema, breathing difficulties, can lead to kidney burden, also reduced the volume of urine lead to kidney failure, so the postoperative patients in stable condition, should encourage and help patients with extra water, and perform 1 weeks observation, urine color, smell and transparency of urine. 2.3 Complications Preventive Care 2.3.1 Puncture nursing puncture subcutaneous hematoma is the most common complication of endovascular puncture intubation due to improper oppression or more patients with no early ambulation, thus pulling out sheath pipe posterior divisions artery puncture point pressure is very important, general artificial compression puncture wound 30 min, or "8" shaped bandage dress
Endovascular carotid stenting is, however, invasive operation, also can't completely avoid the happening of the complications, postoperative nursing work is a powerful guarantee the efficacy of surgery; Through professional training, and establish a preoperative and postoperative nursing monitoring group, implements the system of process type carefully management to ensure successful operation, ensure smoothly through the patients with rehabilitation hospital is of great significance.

Compare with the standard k- model, the RNG k- model is better in the simulation of high strain rate and streamline the large bending degree of water flow in hydrocyclone due to the consideration of rotating machine swirl flow condition in average flow.
The inlet boundary conditions are set at the inlet of hydrocyclone in the calculations, and the fluid medium is liquid water.
Now engaged in professional mechanical professional teaching and research work.

· Interest of Attributes The user selects one or more subsets of AS as the interest of attributes before mining in the light of professional knowledge and requirements.
Meanwhile, in step 6) interest evaluation is done for chromosomes in every generation to take into account the user's professional experience and mining requirements, which would make the mining much more directly.
The parameters determined to evaluate reservoir bed include rock porosity , the relative resistivity F, moisture content of rock resistivity , formation water resistivity, lithology coefficient , structure index , resistance increased rate , resistivity of rock , the coefficient , Water saturation , saturation index , permeability , capillary diameter , total of 13.

Hierarchical description of water distribution network of professional data sheet: Water pipe network professional data layer explains: drainage manholes layer, drainage layer drains, drainage district planning, catchment areas, pumping stations, overflow weir, door, pipe and canal gates, Sluice, drainage households, sewage treatment plant. 3.5 Logical structure design Basic topographic data covers the main city of Kunming, its main function is assisting network data positioning, showing that basic information of the terrain, which is convenient to user positioning and understanding, and at the same time assisting network data calibrate by the terrain attribute. ( It is shown in Fig. 3) The geometric network of Geodatabase model can describe well all the connections between facilities with GIS analysis function of urban drainage system.According to the geometry of these facilities abstract as point elements and linear element.

But both CP and CPr should be applied throughout the remaining service life of a structure and may be controlled and monitored by professionals.
Free chloride content was determined by grinding power in different areas around steel. 2g of the power was immersed in 30mL distilled water for 24h.
Then the water was filtered to get the concentration of chloride ions by a Titrando device.

All measuring operations are the manual skill, it means that the testing operators must be specially trained and have to master the professional theory and testing craftsmanship.
The whole test equipment and measuring process are automatically controlled by the two-stage control system with upper computer and lower mono-plate processor, so that requirement of the professional theory and testing craftsmanship for the test operators is independent and depressed.
