The emphasis was on the cultivation of students' comprehensive ability, including technical knowledge and reasoning ability, personal ability and professional ability, interpersonal skills, as well as in the social environment the ability to conceive, design, implement and operate of the system performance.
As the ball valve was widely used in such as water and gas pipelines, low pressure piping systems, it was common to be seen and used in students' daily life and was not unfamiliar to them.
Pay attention to practice, implement ‘teaching based on the project’ The implementation of ‘teaching based on project’ and ‘learning by doing’ emphasized on the cultivation of students' comprehensive ability, including technical knowledge and reasoning ability, professional competence, interpersonal communication ability and in the social environment the abilities to conceive, design, realize, operate of the system[4].

China's geographical environment: in the eastern climate condition are preferable, water is enough, and so is heat.
In the different environment outdoor woodiness furniture style design can be affected by Terrain Mountain, water and other geography factors, creating the compatible furniture products.
For example, in the southern of China landscape architecture of the water system is a good example.
In the south landscape park, stylist makes full use of the water; let it through every corner of the garden, which plays a big role in adjusting area and landscape.
From the point of view of the professional planning design, the basic elements of landscape can be divided into two sorts: one kind is soft qualitative thing, such as trees and water; another kind is the hard things, such as pavement, the sculpture, the wall body, baluster, landscape building, etc.

Introduction
During the tunnel construction, the occurrence of tunnel geological disasters(such as rock burst , landslip,water gushing,goaf,fault fracture zone) etc. are complex and random .Under the influence of instrument accuracy and technological level, great majority of tunnel construction have the problem —design accuracy is not enough.
Fig.1.1 Water gushing 1 Fig.1.2 Water gushing 2 Fig. 1.3 Water inrush Fig. 1.4 Fracture zone collapse The research of our advanced prediction carried out in fifties of the last century and application to the tunnel construction in the early 1970s.
If the wave encounters different impedance medium such as fracture zone,silt weak zone,cave,water-rich etc.
After the screening of correspond data through the professional processing software , it will be able to interpret the scope, type, and orientation of the front of face geological body.
However, this method can only detect whether the Aquifer is existence, and for specific bodies of water can not be measured.

Second, the lack of innovative professionals.
Enterprises are lack of senior management personnels who have accepted systematic training and are lack of complex talents who possess both management capabilities and professional skills, multi-skilled IT talent, and research talents to apply technology.
Promote the Integration of Resource Elements to Provide Public Goods for the Development of Industrial Clusters Public goods needed by the development of industrial clusters include: the establishment of industrial belts, industrial park and the base as well as the necessary infrastructure, convenient transportation network and communication conditions, ample supply of water and electricity, a full range of specialized wholesale markets, unimpeded logistics system and good ecological environment.

A professional expert opinion is required in the case of a quarrel at law, as the decision depends on the assessment of the facts for which expertise is required.
In particular, the consistency of the fresh mixture which must not change during transport or during the placement of the mixture, and also the compaction where the concrete must not begin to segregate and to sediment, nor must water be separated from it.
For this reason, recycled concrete nor recycled water should not be used for mixtures with exposure requirements.
It is also not recommended for this purpose to use absorbent admixtures in concrete, the presence of which affects sedimentation and water separation.
The water coefficient should not exceed a value of w/c = 0.55 and its value must not fluctuate.

Enzymatic degradation of guar gum
Guar solutions (become gel at required high concentration) were prepared by adding 30 g polymer into 200 ml deionized water under vigorous stirring, if necessary, in order to disperse guar better, 20 ml absolute ethyl alcohol could be added into deionized water before adding guar.
Then, the polymer gel was sealed a container and placed in a 90 ℃ water bath for 2h.
Then, the polymer gel was added into 50 ml water under vigorous stirring, then an appropriate amount of β-1,4 mannanase was added under vigorous stirring, the pH of the guar solution was adjusted to 6 (optical pH for this mannanase, see fig.1) by adding hydrochloric acid, and the emzymatic degradation was carried out in a 50 ℃ (optical temperature for this mannanase, see fig.2) water bath.
(2) The intrinsic viscosity determination was performed in a water bath at 25℃.
