Another issue of concern is that, because the network is usually more widely distributed today, so an attacker can control multiple puppets machine to effectively hide their true position, which is bound to involve tracing the attacker more time to large network range, more agencies and departments, will also spend a lot of manpower, material and financial resources.

The Growth Charactersitics Study of Introduction Fast-growing Poplar at the Initial Stage of Afforestation Peiyong Lian1, a, Jinye Liu1, b, Liankuan Wang2, c 1Daxing’anling Academy of Forestry Science of Inner Mongolia, Yakeshi, PR China, 022150 2 Dayangshu Forestry Bureau of Inner Mongolia Dayangshu, PR China, 165456 akeyansuolpy@163.com, bye0607@163.com, cdyslyjwlk@163.com Keywords: Fast-growing poplar, Introduction, The initial stage of afforestation, Growth characteristics Abstract.
In poplar cultivation process, stand density is one of the important factors that affect the growth of trees; its size is directly related to the forest stand growth, yield and quality, there are varying difference degrees of wood quality and fiber yield in different density level, directly affects the forest industrial raw material utilization value.

Suppose that a solid porous substance consist of combustible and inert components, and at the same time the solid combustible material transforms into a gas in the reaction with gaseous oxidizer, so we have the following expression: Solid Fuel + (μ)Oxidizer→ (1+ μ)Gaseous Product (1) where μ is the mass stoichiometric coefficient for oxidizer.

CI belongs to knowledge-intensive industry, and one of the key differences between the knowledge-intensive industry and traditional industry is the use of resources mainly focusing on human resources, rather than the traditional material resources, financial resources, which will lead to knowledge-intensive industry needing in the region of the abundant human resources in order to have a more lasting development.
