查询词典 transition element

We are now at a transition period, the transition period, we should put up with slightly lower economic growth, because in transition, when there are labor pains.

The phase transition temperature increases and the transition ranges tends to be broad when PNIPA brushes were substituted with P or P(NIPA-co-NVP) brushes obtained by the copolymerization of NIPA with AA and NVP, respectively. However, the phase transition is not obvious if adding excessive hydrophilic comonomer.

结果表明，纯PNIPA刷的相变温度在29℃~33℃之间，通过共聚所得的单一P或P(NIPA-co-NVP)刷均使相转变温度提高，转变区域拓宽，当亲水性共单体的量过多时会导致相变过程不明显。

Calculating results show that variation of the propellant inlet pressure makes little impact on engine performance parameters, and the engine will transit to a new stable state. The parameter transition curves are smooth. When the engine thrust is adjusted in a small range within a short period, the parameter transition curves are also reposeful. But when the adjusting range becomes large, the parameter transition curves will fluctuate acutely. Thus, when large range adjusting is required, the time of adjusting should be lengthened or the adjusting should be divided into adequate steps.

计算结果表明，当发动机在某一个稳定工况工作时，发动机入口推进剂压强的变化对发动机性能参数的影响不大，发动机的参数都能比较平稳的过渡到一个新的稳定工况；当发动机在短时间内进行小范围的推力调节时，发动机参数的过渡过程的曲线也比较平稳，但是当在短时间内进行大范围推力调节时，参数的过渡过程的曲线振动比较剧烈，因此应当在进行大范围推力调节时，应当对调节时间进行适当延长，或者分级进行推力调节。

Analysis is conducted on model checking for three valued logic formulae of modal transition system using existing model checking techniques. We reduce the three valued logic model checking problem for modal transition system to the two valued model checking problem under Kripke structure. This reduction is linear in the number of states, size of transition relations, and number of atomic propositional formulae in the new formed model compared with those in the original model. It does not increase the comple...

Firstly, system model depicted by TSIOA is transformed into an USTGSS (untimed stable label transition graph of symbolic state) which does not contain abstract time delay transitions. Then, the testing methods based on LTS are used to the generate transition sequences from USTGSS according to structural coverage criteria. Finally, a process of constructing and executing the test cases is given, in which object functions of time delay variables are imported, and time delay variables used in the transition sequences are solved dynamically by linear programming techniques.

We especially inspect the function of demographic transition to economic growth after analyses compositively the mainstream theory of economic growth. With the analytical framework of "demographic dividend" theory, we examined China's economic growth miracle from its openness and reformation, exposed the important action of demographic transition to China economic development, and validated the existence of "the first demographic dividend" in the process of China demographic transition.

In the 1980s,developing countries realized the transition of politics one by one.The study on political development and political transition became the hot issue again. In the early 1990s,Russia began its political transition under delegative democracy which came from its political historical background and actual situation.

20世纪80年代，发展中国家相继实现了民主政治转型，政治发展、政治转型研究再度成为政治学界的热门课题。90年代初，俄罗斯走上了政治转型道路，特殊的历史背景和现实环境使之形成了独特的政治转型模式。

In this thesis, the crystal structure and phase transition behaviors of a andβforsterite (Mg2SiO4) at high temperature and high pressure were investigated by the first principle calculations and the quasi-harmonic Debye model. Variations of elastic properties, band structure, density of state, band gap ofαandβforsterite with pressure were calculated, and the effect ofα/βphase transition on these characters was analyzed. The effects of water on elastic modulus, sound velocity and band gap of forsterite were also simulated. Finally, the effect ofα/βphase transition and water on seismic discontinuity in earth was discussed.

Firstly,based on the B.Bowermans result about the rate of convergence in Cesaro sense of certain nonhomogeneous Markov chains which the transition matrices converge,we are to study a certain nonhomogenous Markov chains which the transition matrices average converge to a period strongly ergodic stochastic matrice,and control the average convergenc rate of transition matrices,then we get the rate of convergence in Cesaro sense about the nonhomogeneous Markov chains by used the character of norm and the character of nonhomogeneous Markov chains.It is an extension of a B.
