扰动

Daya Bay was shown to be ecologically disturbed and the stability of macrobenthic community was weak. Specifically, the inner bay and main area of the central bay was strongly disturbed and was dominated by Group Ⅰ community that was characterized as simple low stability and dominated by molluscs. Dominant species were Veremolpa micra and Timoclea scabra.

The disturbing rields caused by the speedup and quietude of upper crustal movement in Tibetan Plateau indicate that, when the upper crust movement is speedup in Tibetan Plateau and keeps the boundary condition unchanged, the energy stored in upper crust is released, the driving force by Indian plate increases the horizontal compression stress and movement in other layers in Tibetan Plateau, and increase the horizontal compression stress in the whole geosphere in North China area Comparing the disturbing distribution of horizontal compression stress in the upper mantle layer, the value in North China area is only about one twelfths of that in south part of Tibetan Plateau.

3青藏高原地区地壳非均匀活动在中国大陆岩石层引起扰动场的研究结果表明，在保持板块边界作用强度不变的情况下，青藏高原地区岩石层上部地壳运动的增强，增加了其岩石层下部的向前推挤，同时也增加了对其它块体的推挤作用，以上地幔盖层内最大水平主压应力的扰动值为例，华北地区比青藏高原南部地区小一个量级。

分析各自的演变过程，发现在MTC的发展过程中，西风扰动类MTC基本处于准静止状态略有西移，而东风扰动类MTC由于其发展过程的独特性，往往向西北方向移动并且移速较大。

In this paper, the study about the interactionbetween the solar wind disturbance and the current sheet is mainly carried out intwo aspects: First, the characteristic propagating of this kind of CMEs erupting inthe open magnetic field between two helmet streamers has been studied by theMHD numerical simulation. Second, the Hall effect during magneticreconnection has been studied respectively through numerical simulating andtheoretically analyzing. And some of its characteristics have been discussed inthe aspect of the interaction between the disturbance and the sheet current.

论文主要从两个方面研究了太阳风扰动和电流片的相互作用：其一，对爆发在两冕流结构间的CME的传播特点进行了MHD数值模拟研究；其二，对磁重联过程中的Hall效应进行了数值模拟研究和理论分析，从扰动和电流片相互作用的角度初步探讨了Hall效应的一些特征。

Considering the disturbance of reaction wheel assembly is related with the fixing condition, two methods named 'rigid six-axis test bed' and 'flexible six-axis test bed' were adopted respectively to measure the disturbance. Measurement results of two methods were compared through three aspects.

仿真结果表明，由于温度效应和中毒效应的存在，核反应堆对反应性阶跃扰动和冷线温度阶跃扰动有一定的自稳定性，该特性满足核反应堆在设计时的目标。

Under the precondition of assuming the stock price did not following the famous geometric Brown law, and agents have no exact knowledge of the probability distribution for the uncertain economic shock and return rate perturbation, chapter five presents the uncertain dynamic models of portfolio choice and option hedging respectively. In this chapter, we define the H〓 norm of transfer function from disturbance input to control output as financial risk measurement, and investigate the risk-attenuating robust H〓 portfolio investment and option hedging strategies.
