Scholars and professionals in many countries have always been attempting to improve the production of xylanase.
After cultivation, the cells were collected by centrifugation (3,000 g×15 min), then washed twice with distilled water and 50 mmol/L phosphate buffer (pH 7.0), finally lyophilized for 24 h by a freeze drying system.

The green body of porous RBSC support for candle type RBSC hot gas filter (inner diameter : 40mm, out diameter : 50mm, length : 500 mm) was fabricated by ramming SiC/carbon black/phenol resin/water mixture slurry into the steel mold.

At the same time, Using the FLAC3D powerful post-processing to do numerical simulation of the model, we can draw a variety of ideal analysis data, provide the basis to determine to technical professionals, ensure the scientificalness of the technical implementation [3].

Meanwhile, they should improve the arrangement of professional curriculum according to market demands which serve as a foundation, and adhere to conducting market research.
In this way, colleges and universities can adopt related measures to increase employment rate of graduates, such as increasing opportunities for social practice, adjusting professional curriculum and keeping contact with employers to listen to feedbacks.

Problems of Doors and Windows Stucco Construction Traditional windows and doors installation and construction often arranged before the wall paint job, the Practice has proved that the construction method has poor water resistance, the sash is easily damaged and long construction has period shortcomings. 
In addition, the construction unit should be targeted at different types and different people carry out the necessary safety knowledge, education and professional skills training. 
At the same time, the construction unit of the construction work is important to organize professional and technical personnel serious triage construction drawings, and should be strictly in accordance with the specific circumstances of the construction project, optimize the construction drawings to eliminate some of the dominant issues of the construction drawings and hidden issues. 

They outline the parameters which specialists should adhere to: 1. secured fairness and transparency of the whole process of resource efficiency evaluation; 2. respect for safety and dignity of people who experts interact with in the evaluation process; 3. presence of professional obligations which are defined by the public interest and the public good [1].
There exists another approach to evaluating resource efficiency of foundry technologies, which presents a more professional focus.
Turilova suggests a whole set of parameters to evaluate the efficiency of foundry technologies: • liquid metal-to-finished casting mass ratio; • energy consumption per casting unit; • energy consumption per production unit; • water consumption per production unit; • amount of wastewater per production unit; • percentage of scrap; • percentage of defective products; • amount of generated waste per production unit; • proportion of waste returned to production; • recovery factor of molding sand; • output volume per employee; • ratio of costs and general administrative expenditure to the cost of marketable products [3].

As the engineers on board are not hydraulic drive professionals, they generally lacks of relevant theoretical and practical experience, it is very urgent and necessary to improve through training.
The third stage, FBX files are imported into Unity 3d development platform for simulation-driven, script programming language is C #, other virtual environment required by the system is built up directly by Unity 3d tools, such as the water prefab is used to implement wavy sea surface, the terrain system is used to implement coastal mountains, and the ultimately finished crane rotary system which is one of the total three is shown in Fig.2 .

The accelerated cooling mode is determined by the coolant flow rate (water) through the collectors and the running speed of hot rolled breakdown in the area (RS).
This leads to a different flow of phase and structural transformations along the sheet thickness and, therefore, the need to take into account the conductive interaction of different layers of the strip, both in terms of heat removal by water and the transfer of the thermal transition effect.
• Possibility of “manual” adjustment of a number of input parameters of the model (temperature of the end of rolling, speed of movement of the roll in the accelerated cooling, water consumption by collectors of AC, thickness of the roll).
By modeling the structure formation in the researcher's workstation, the professionals can fine-tune the production process mode in order to obtain the required uniformity and dispersion of the microstructure of the final product.

With the development of human activities and irrational exploitation of water and soil resources, the problem of water loss and soil erosion has caught the attention of the world.
As defined in the Amendment (1997) to American Clean Water Act, non-point source pollution shall be with implication that certain pollutants are, in an extensive, diffused way and in trace amount, creeping into surface water and underground water.
Note: Aforementioned information modified from the professional literatures[35] Theory & method for total quantity control of non-point source pollutants in agriculture Estimate to water-environmental capacity and its distribution amongst varied pollution sources and regions are the foundation and core for total quantity control of water pollution[36-43].
By taking advantage of the model of water volume and quality for receiving water body at river catchment areas, it is mandatory to evaluate current situation and to forecast the situation of water quality over land surface, and to compute water-environmental capacity, in consideration of water functional zoning within areas being studied and upon water quality being controlled.
Comparing water quality over land surface with water-environmental capacity of corresponding pollutants, carry out a review of the river-entry reduction or remaining water-environmental capacity.

Bidding for construction units themselves, but also pay attention to see if the tenderer has the capability of preparing his tender documents and organizing bid assessments; Whether or not the project subject to tender according to law must, has been to the relevant administrative supervision departments for the record; 2) Have adapted to construction project funds or sources of funds; 3) Have adapted to construction of professional and technical personnel and management personnel, if not have, whether to entrust to have the corresponding qualifications agency agent; 4) Whether the preliminary design scheme has been approved; 5) The construction is included in the annual plan; 6) Design drawings and relevant technical data can meet the construction needs; 7) Relevant aspects have any bad record. 1.1.2 Pay attention to review the legality of the bidding documents The contents of the bidding documents shall be: 1) Tender notice of basic requirements: Scope of project summary, bidding
The provisions on the bidding scope and scale standards for construction projects to further refinement, the above conditions of the specific provisions are as follows: 1) Must invite public bidding of construction projects: single estimated contract price is in 2 million yuan of above; The project total investment in 30 million yuan of above. 2) Relationship between social public interests, the public security infrastructure project scope: coal, oil, natural gas, electricity and other energy projects; Railways, roads, pipelines, aviation, water transport projects; Post and telecommunications, communications, information networks and other telecommunications project; Flood control, irrigation, water diversion, water conservancy, water and soil conservation, water conservancy project; Roads, Bridges, rail transportation, garbage disposal and sewage disposal, underground pipelines, urban infrastructure projects such as public parking lot. 3) Relationship between social public interests
