查询词典 stable state

Similarly, we have investigated the stable structure of Ge20 and found that its ground state structure is different from that of Si20. But the most stable structure is also a stacked structure from the ground state structure of Ge10 (tetracapped octahedron with Td symmetry), which is in agreement with the fragment experiment.

类似地，我们首次对Ge20团簇的稳定结构进行了同样的研究，发现它的基态结构与Si20团簇的不同，但它同样以Ge10团簇的基态结构（四帽八面体，Td对称性）为单元的一个堆积结构，这与碎片实验结果吻合。

The results show that the most stable P5 is the doublet state of b isomer evolved from regular tetrahedron P4 while the most stable P(superscript + subscript 5) and P(superscript - subscript 5) are the singlet state of e, j isomers evolved from square P4, respectively.

结果表明，最稳定的P5为由正四面体的P4演变来的b结构的二重态，P(上标+下标 5)和P(上标-下标 5)则为由正方形P4演变来的e结构和j结构的单重态。

Aimed at the problem of choosing the initial value when the Newton method is used to compute the controlling unstable equilibrium point, a practical and rigorous solving scheme was presented: by identifying the controlling load bus of the given fault, and using the Thevenin equivalent circuit to represent the rest of the system at the state of the post disturbance stable equilibrium point, using the steady equivalent circuit to represent the induction motor in composite load, and then using the torque characteristics of induction motor, a point near the CUEP is gained to be the initial value. The second order normal forms was used to approximate the stable manifold of CUEP, and the local approximating boundary of the region of attraction of the post disturbance stable equilibrium point was gained. Then just by simulating the state of the system at the fault clearing time, the transient voltage stability of the system could be determined.

针对采用牛顿法求取故障后系统主导不稳定平衡点(controlling unstable equilibrium point，CUEP)存在的初值选取难题，提出一种实用但不失严谨的解决方案：通过识别给定故障的主导负荷母线，对主导负荷母线以外系统由故障后稳定平衡点处的状态进行戴维南等值，对负荷中感应电动机部分采用其稳态等值电路，再由感应电动机的转矩特性求得CUEP附近的一个点作为近似的CUEP，以此为迭代初值可靠求得CUEP；采用二阶正规型来近似CUEP的稳定流形的方法求得近似的局部吸引域边界；由仿真得到故障清除时刻系统的状态并根据该状态是否位于吸引域内判断系统的暂态电压稳定性。

It is confirmed that under the illumination of light the dark-adaptedBR is quickly turned into the light-adapted, and undergoes a photo-chemical cycle then through a sequence of intermediates of J, K, L,comes into a more stable intermediate-M state. M state relaxes to B state in about one hour. B state converts completely into D state after 24 hours. B state initiates the photochemical cycle under illumination, while it can transform into D state in the dark. So B state is a key intermediate in the BR photochemical cycle.

实验证实，样品受光照激发后很快从暗适应型经过光适应型进入光循环，经过一系列的光化学中间体到达较稳定的M态。M态经过约1小时热驰豫完全回到光适应型B态，B态再经过24小时缓慢热驰豫完全回到暗适应型D态。B态受光则进入光循环，不受光则转化为D态，从而认为B态是菌紫质光循环路径中一个重要的分支节点。

After analyzing their calculation principle, the authors believed that the reason for these differences was that the prerequisite calculating the stable-state geothermal temperature filed was untenable in some areas with possible unknown underground heat events, then the thermal Curie point isotherm derived from this method would not show the actual Curie point isotherm in such areas.

笔者认为造成这种差异的主要原因在于，在有可能存在未知热事件的地区，计算稳态地温场的前提条件并不成立，因而由这种方法计算出来的热居里面在这些地区并不能真正反映居里面的深度，从而形成了它与磁居里面的显著差异。
