The effectiveness of thidiazuron（TDZ）on adventitious bud and shoot formation from leaves of Robinia pseudoacacia was tested in combination with naphthaleneacetic acid （NAA）or 2,4-dichiorophenoxyacetic acid （2,4-D）,With the increasing of TDZ level,the induction rate of adventitious buds appeared an increasing trend and the highest rate was obtained by the combination of 2mg/L TDZ whth 0.1mg/L *** excessive level of TDZ could induce useless cellae and easily produce *** of shoot elongation by TDZ was overcome through transferring shoot cultures to a shoot proliferation medium lacking TDZ orcontaining NAA,benzyladenine （BA）and ***-3-butyric acid （IBA）was used to stimulate the rooting in vitro .Based on the number and length of rooting ,the treatment with 0.5mg/L IBA was the best.

通过对FGH96粉末高温合金、DZ125定向凝固高温合金、DD6单晶高温合金大量疲劳断口的断裂特征进行统计分析,研究了这3类镍基高温合金疲劳损伤的微观机制。结果表明,这3类合金疲劳断裂的宏观形貌有较大的区别,但由于这几类合金均为镍基面心立方晶体结构,因此其疲劳损伤断裂具有相同的微观演变规律和断裂机制,即:从疲劳裂纹的萌生至裂纹的快速扩展均是以滑移机制进行;疲劳扩展第1阶段均为类解理特征,疲劳扩展第2阶段为疲劳条带,快速扩展区呈现为滑移面、滑移台阶、韧窝特征。由于其组织和成形工艺的区别,其共同的特征表现的具体形貌有所区别。

MODEL OF STRATEGY SYNERGY IN NETWORK ORGANIZATION BASED ON M...

2005年中国机械工程学会年会

作者： XIE xinling, liu Wei, CEN Yiwan (Chongqing University, Chongqing, 400044, China)

＜正＞Network organization is an organization built by some rules among organizations for some purposes or some tasks. It is a new type of organization between traditional organization and market mode style organization. It is necessary to cooperate with the strategy in order to realize the strategy synergy and make the network organization get the stronger competition priority in the modern commercial field. The strategy synergy includes the exterior synergy and the interior synergy. When we put the strategy in practice, it is not a wise idea that we consider the single member in the network organization only. On the contrary, we must study the synergy of the strategy among the members in network organization and the synergy of the strategy in the single member. MAS is an abbreviation of multi-agent system which composes with many agents, and each agent has the outstanding characteristics of agent, intelligence, self-determination, and so on. The technologies of agent and MAS are used and extended in the network organization’s strategy synergy. The model of the strategy synergy in network organization is studied and built. The global strategy in network organization is acted as one MAS system, and other sub-strategies of the members are acted as the agents in the MAS system. The technology of modeling is used to reach the goal of strategy synergy in network organization. Because each agent in the system is an intelligent and independent object, it can guide its action based on the knowledge storeroom when the exterior environment changed. It can also adjust the collisions through the integration synergy module when any collisions occurred. At last, base on the above model, a management system used to cooperate with the strategy in network organization is built in order to improve the competition priority of the whole network organization.
