查询词典 state system

When the sojourn time of deteriorating state, inspection interval and maintenance time are the stochastic variables which follow the general distribution, the phase-type approach is proposed to preserve the analytical tractability of the transition probability matrix. To solve the problem that the PH distribution changes the state space of system, the value iteration algorithm for the semi-Markov decision process is improved to get the optimal inspection and maintenance policy.

And three main steps of all subspace algorithms are explored. First, using an LQ-decomposition, the projection of the row space of specific data Hankel matrices is calculated. Next, the SV-decomposition of the projection is calculated to directly lead to the observability matrices and a Kalman filter estimation of the state sequences. Last, the system matrices are extracted from the observability matrices and/or the estimated state sequences.

At present, besides keeping the higher increasing rate in petrochemical industry, most of others original state-owned and city-owned industrial enterprise bankrupted and stopped production in the process of economic system reform and the transition of state-owned enterprises, resulting in the appearance of a large number of laid-off workers which lead the increasing amount of urban poor class in the city.

目前，处于经济转型时期的兰州市除石化产业仍保持较高增长外，其他原有国有及市属工业企业大多在经济体制改革、国有企业转轨过程中破产或停产，出现了大量的下岗职工，使得城市贫困阶层的数量不断增多。

The P.pratensis community is in the phase of herbs and forbs of degraded alpine meadow.At the same time the P.pratensis population is in the dominant spices position,subordinate spices position and company spices position.So,we can replant P.pratensis and other grass seed to change the structure and composition of plant community,improve community environment,cause it to develop to subclimax community succession,reach the stabler state.We can apply fertilizer,improve soil nutrition condition,enable degraded grassland with the link of soil and vegetation system together to reach the stabler subclimax and climax state.
