( " ;4 ) provisions of the new China principle. The common programme set :" ;safeguard national independence ,freedom and sovereignty and territorial integrity ,maintenance of
Adidas Jeremy Scott Wings 2.0 lasting international peace and friendly cooperation between the people of all countries ,and oppose the imperialist policies of aggression and war " ;4 ,the victory of Chinese revolution .
What are the main reasons ?( 1) the leadership of the party : the first is due to the leadership of the Communist *** of China .Chinese Communist *** as the political party of the working class ,not only represents China the interests of the working class ,but also represent the whole the Chinese nation and the entire Chinese people interests.
The Communist *** of China is with Marx scientific theory armed with China ,the Marx doctrine that Mao Zedong Thought as the guiding principle of all work .To formulate suits Chinese situation ,in line with the interest of the Chinese people ,route ,policy programme and policy ,as the Chinese people to go in the right direction .
." ;No Communist *** ,then there ." ;this is the Chinese people based on their own personal Experience of the confirmation of the objective truth .( 2) people participating extensively :workers ,farmers ,city small bourgeois democratic revolution mass is the main force, the national bourgeoisie has also gradually to the
www.adidasjeremyscottc.com Communist *** .
No majority of the people and people from all walks of life widely participate in and support energetically ,the victory of the Chinese revolution is impossible. ( 3 international help ) : the Chinese revolution can win ,with the international proletariat and the masses of the people support is inseparable.
5 ,the victory of Chinese revolution basic experience (1 ) establishment of a broad united front. The United Front has two union: a workers Union ,which is the basic ,main ;one is laborer and labor union ,this is the auxiliary ,is also important.
We must rely on the first union ,for the establishment and expansion of second union. The consolidation and expansion of the united front of the key ,is to insist on working class leadership ,led the allies to the common enemy resolute struggle and win ;to be leaders bring material benefits ,at least not damage their interests ,but also on the leader to give political education ;the bourgeois take jointly ,and struggle ( 2 policy.
) adhere to the revolutionary armed struggle .China revolution only to take armed struggle as the main form. China is essentially the armed struggle led by the working class peasant war .
We must deeply rural land revolution ,walk the countryside surrounds the city road ,in order to gradually to strive for the victory of the revolution .We must establish a branch under the absolute leadership of the Communist *** the new people ,the army must execute a series of with Chinese characteristics of the people war strategy and tactics

The method actually allow formed on the sidewall of small cracks ,and then use the bridging particles in the wall crack of block cracks and openings .This bridge plug must be low permeability ,but also can supply pressure packer .
On the borehole wall or wall adjacent to bridging crack growth of borehole surrounding annular stress ,this approach is called the stress shielding effect in drilling ,drilling fluid by continuing to increase the amount of particulate material ,so that the drilling fluid continuous produce this kind of role.
The drilling fluid is called multifunctional drilling fluid .If the formation under pressure to produce radial cracks and crack size and formation of hardness is the function ,then can list type := t t type :for cracks of excessive pressure ( excessive pressure refers to the pressure exceeds the minimum real stress ) ;W for crack width for fracture of radius ;R ;E formation Young ;V as the formation of Poisson on the fracture type .
In theory .The multifunctional drilling fluid is the use of bridging particle plugging cracks open to control crack crack excessive pressure is bridging particle mechanical stress exerted replacement .
so we can not directly use to calculate stress shielding effect on borehole strength. But the type helps to understand the importance of the use of type parameters .The sensitivity analysis, and watched some useful phenomena
1) when the crack width is small to 1mm ,while fracture radius category 1m, wellbore strength can be added to 1000PSI ;( 2) a short crack or support the crack length is best, if
Adidas Jeremy Scott Wings there is support for the crack is very long, cracks are easily cracked again ,and when cracks widened to achieve the same strength ;( 3) soft rock large crack width ;( 4) .
