Abstract.
That is to say, the CNPC is responsible for decision and general coordination, the project manager department is responsible for management and project implementation, professional construction unit is in charge of construction
In the period of rolling development of exploration and development, aiming at the problems of thin underground oil layer and complicated distribution, development department intervene in the meanwhile, strengthen the fine description of reservoir, accurately grasp the distribution regularity of oil-water, design oilfield development scheme scientifically.

Thus customers can utilize the resources just like the way to use tap water, electricity or gas.
3 Models
There are three roles in the Cloud Manufacturing as in the Cloud Computing, namely the resource provider, the platform manager or operator, and the resource user.
The resource user, or customer, can utilize the resources just like the way to use tap water, electricity or gas.
The enterprise put money to the construction of the platform; the resources, basic data and related infrastructure are held by the enterprise himself, but the operation or maintenance of the platform is outsourced to the professional CSP (Cloud Service Provider)

Fig 3 is the TG curses of perlite-based composite phase change energy storage material, it shows that in the cause of constant temperature 75℃, 20 minutes, its weightlessness rate is only 4.35%, it might be mainly the dehydration of composite PCM sample, it’s because a small amount of water vapor in the air was absorbed on the perlite-based materials in the prepare process of the materials, when it is heated, this part of water vapor was taken off firstly, but the phase change energy storage material in the perlite-based materials has no any loss, it indicated that the prepared PCM had a good thermal stability.

Therefore understanding the behavior of a mixture during this particular period is a crucial requirement for the technical and economical success of professional production sites.
Except for the amount of superplasticizer, the volume fractions of the other ingredients in the paste mixes were kept constant and the volumetric water to cement ratio was thus kept equal to 1.13 (Table 2).

Population growth in the world has caused an increased demand for resources, energy, food and water.
The importance of forests is critical because they play very important ecosystem roles such as the release of oxygen and carbon capture, maintenance of water and biodiversity, protection against erosion.
Among bamboo’s applications, few should be cited, such as: A) Agriculture: it is used for irrigation of soils and crops; its tubular structure facilitates the water transport from the source to local irrigation [17].
In this way, faced with the current energy crisis, global warming and socio-environmental stresses, the use of non-conventional sustainable materials and technologies becomes a great ally for minimizing the impact of those conventional, and encourage changes in attitudes of professionals involved more specifically in the environmental conservation in Brazil.

As a matter of fact, the subway construction has the characteristics of large-scale investment, long construction cycle, complex professional division of labor, and great technical difficulties, etc., although cooperated-building parties attach great importance to safety management work, the risk accidents still happen often, which causes a great economic loss to the country and produces serious social impacts.
The risk identification expert system is an effective way to solve the above problem, which can effectively utilize experts’ many years of accumulated experience and professional knowledge through simulating expert thinking process. 2.
Flow sand refers to after the soil granular is saturated by ground water , due to the existence of the head, dynamic pressure will make these granular produce suspension flow.
The causes and risk factors include: ①retaining pile or ground even if wall into the rock, ②the variation of water head difference between the inside and the outside,③the basement formation geological, ④the foundation pit bottom weak formation is strengthening or not, ⑤the ratio of the retaining pile the ground wall in the dust, ⑥the soil thickness of the basal. 3.2 Risk identification fact Base Construction In general, fact base consists of fact ID, fact description, status, and facts determination and its credibility,which it can be expressed by table structure.

Technique procedure: Glutinous rice and grits were soaked in water for 4h and then steamed for 5 min.
After that, stirred up the rounded masses, continued to be steamed for 25 min and then showered them with cool boiled water to about 30℃, inoculating Angel Rhizopus Sp., incubating the materials at Constant Temperature until they had a desirable flavor and taste. 2.3 Measurement Indicators and methods 2.3.1 Sensory evaluation: 10 professionals were chosen to evaluate rice wine and yogurt with rice wine flavor in sense perception.
°T stands for the Unit. 2.3.3 Determination of reducing sugar: The Fehling reagent hot titration method (GB/T 15038-2006) was used: in every 100g of rice wine juice contains glucose's number. 2.4 Flavor analysis of rice wine 2.4.1 Head Space Solid Phase Micro-extraction (HP-SPME) Aromatic compounds from the rice wine samples were extracted by HS-SPME and analyzed using gas chromatography/mass spectrometry. 3g wine sample, 3ml distilled water and 1g NaCl were placed in a 15-mL sample vial.

Standard quercetin (Tokyo Chemical Industry CAT 849061-97-8), standard chrysin (Sigma Aldrich USA CAT 480-40-0), and water for injection (PT.
Quercetin is very soluble in ether and methanol; soluble in ethanol, acetone, pyridine, and acetic acid; and insoluble in water [21].
Research conducted by Dong et al. (2021), stated that chrysin compounds had the highest solubility values in dipolar aprotic solvents, such as dimethylformamide (DMF), acetone, and ethyl acetate, had moderate solubility values in polar protic solvents such as n-butanol, isopropanol, n-propanol, ethanol, and methanol; and had the lowest solubility value in polar aprotic solvents such as hexane and water [24].
