Drilling fluids can basically be divided into two types: water based muds (WBMs) and oil based muds [2] (OBMs).
The mixture was then transferred to a dropping funnel. (2) A 250mL 3-necked round-bottom flask equipped with a reflux condenser, a dropping funnel and a magnetic stirring bar was charged with 75ml deionized water and 0.2g potassium persulfat. (3) The flask was immersed in water bath at a constant temperature of 85°C.
For water droplets in oil, the emulsifiers are distributed around the water-oil interface.
OBM samples with an oil/water ratio of 85:15were formulated as shown in Table 2.

China ecological residence technology evaluation manual (abbreviation: EM) is issued by National Association of Real Estate, which is the professional guiding document about the ecological residence evaluation.
We should respect the present land situations to protect water and soil resources, improve the efficiency of land use.
Giving full play to the advantages of base is necessary for the sustainable development of residential areas; Living buildings and the environment are the inseparable parts, among which some indexes are more standards in principle; Paying attention to resource recovery and recycling, as well as energy saving and renewable resources (Water, energy, land and material saving); Each system stresses on water resources regeneration and utilization, waste water collection and management and water saving; Energy efficiency and renewable resource utilization are both important; Put emphasis on protecting the ecology environment of residential areas, reasonable traffic organization and reduction of energy consumption brought about by traffic.
Through comparison we conclude three factors that four standards can consider: the rationality of water planning, rainwater disposal, recycling and water conservation measures.
For example, adding detailed complements to ecological function evaluations of water body and greening layout, as well as open space setting reasonable factors.

Reagents were prepared using Millipore ultrapure water (18MΩ/cm), unless otherwise specified.
In a round-bottom flask, 100 mg of CTAB was dissolved in a solution comprised of 48 mL of deionized water and 0.35 mL of 2M NaOH.
Then, 1 mL of deionized water was added.
The sediment was washed 3 times with 200 µL of deionized water and centrifuged again at 10,000 rpm for 3 min).

Imagery processing was carried out in ENVI, a professional remote sensing images package.
In contrast to the urban area, the water (ponds and reservoirs) almost showed an opposite trend.
Overall, the shape of the water body is getting more irregular in terms of AWMSI.
In addition, river was also the major water supply source and the sewage outlet.
This may account for the decreased total number of water body, and the smaller average size.

Bank business: the relevant regulations concerning the credit standing of banks, commissions, letters of credit and letters of guarantee. 3 Implementation Risk 3.1 Design Risk [8,9] J1 Design responsibility: The contractor shall be liable for certain errors or mistakes probably existing in “clients’ requirements”[10]; J2 Technical Standards: China’s design specifications and standards are inferior to the international ones coupled with the variegated technical standards; J3 Adoption of new technologies: Application risks brought about by the new technologies; K1 Quality of the design documents: The selection of technical solutions, the quality of the geological survey reports and omissions, faults, errors and contradictions existing in the design documents and the timeliness of the design changes, etc; K2 Examination of design documents: the clients’ repeated examination of the design documents of the same version; K3 The coordination and cooperation among all professional
teams: the immature conditions for salary raise are likely to lead to the amendment of the professional design. 3.2Purchase Risk (1)Provisions and supervisory risks in the clients‘purchase as stipulated in the contract L1 Goods Purchase: Clients will define the scope of the suppliers and the protective policies; equipment import and export restrictions; L2 Purchase Control: Delayed examination and approval of the clients and the improper full-range monitoring, inspection and acceptance
(2) Risk in construction management P1 Supporting Conditions for infrastructure: whether water, electricity, transportation, place, telecommunication, etc., are complied with the construction requirements； P2 Sub-contractor Management: The selection of sub-contractors, interface division, on-site management and coordination efforts and capacity, etc; P3 Personnel Management: the work efficiency, management condition and psychological counseling, etc; P4 Construction Materials: the problems related to the goods, quality, prices and time, etc; P5 Machinery and Equipment: Problems related to the Supply, maintenance condition and capacity of the construction equipment and accessories or components; P6 On-site Operational Environment: HSE (Health, Safety, Environment) requirements and penalty [13]; P7 Contract Management: the contract management awareness is rather poor and the claim for compensation and counter claim is not properly arranged.

Jorn-Henrik et al [15] states that lack of professionals in production area, leads to irregular monitoring of work schedule and line area.
This risk includes socio-technical accidents such as equipment malfunctions, machine breakdowns, disruptions in the supply of electricity or water, IT failures or breakdowns, in addition to local human centered issues.

About 10g of soil sample was diluted with distilled water in a sterile tube.
The soil suspension water is then poured and spread on the cetrimide agar plates.
Water was added into the microcosm to maintain its moisture content at 60%.

Mortar is one of the essential materials in construction engineering, its components include cementitious materials, mineral admixture, fine aggregate, water, and admixture, etc.
The water reducing agent is polycarboxylic acid high performance water reducing agent, the water reducing rate is about 22 %.
The additive is hydroxypropyl methyl cellulose ether in the form of white powder. 2.2 Test protocol and test specimen preparation 2.2.1 Mix-ratio design scheme Design-Expert software is a powerful professional experimental design software, in which the Center Composite Design (CCD) and Box-Behnken (BBD) design are the more widely used response surface design methods [13].
Chamber to maintain the temperature (20 ± 1) ℃, relative humidity of 90 % or more, the specimens should be maintained at a certain distance from each other, and the specimen on the surface of the depth of water should not be less than 5mm, maintenance period can only be added to the water is not allowed to change the water.
This is due to the small particle size of the fly ash particles, the specific surface area is larger, with the increase in the amount of fly ash mixing, the cementitious material water requirement also increases.
