The strategies of high order sliding mode control and sliding mode control with integral action are proposed. Without losing the virtue of robustness and the ability of eliminating disturbance, these strategies can minimize the chattering phenomenon which is quite common in conventional sliding mode control.

在研究中，提出了高阶滑模控制和带积分的滑模控制方法，这两种方法在保证了常规滑模控制的强鲁棒性和抗扰动能力的前提下，可以在很大程度上削弱抖振，对常规的滑模控制有较大的改进。

In the core of the larger spiral structure of NGC 1300, the nucleus shows its own extraordinary and distinct "grand-design" spiral structure that is about 3,300 light-years long. Only galaxies with large-scale bars appear to have these grand-design inner disks — a spiral within a spiral. Models suggest that the gas in a bar can be funneled inwards, and then spiral into the center through the grand-design disk, where it can potentially fuel a central black holes. NGC 1300 is not known to have an active nucleus, however, indicating either that there is no black hole, or that it is not accreting matter.

星系演化除了像两个星系相撞那样的剧烈作用之外，还有自己内部很慢的演化，因为一个星系总会有一些引力不稳定，如上图中的NGC1300，它是一个棒旋星系，这种bar结构导致的引力不完全对称会驱使很多气体和尘埃损失角动量往里面落，我们可以清楚的看到dust lanes，有点像黑洞的吸积，但这个星系是个非活动星系，目前还没有黑洞存在的明确证据，but我相信肯定是有的，没有比在星系中心放一个黑洞再完美不过的事情了，或许这些下落的dust lanes是黑洞发光的开始呢。

It's always great to actualize all the potential you have.

At the same time, for the process additive and multiplicative uncertainties mostly encountered in practice, the sufficient and necessary conditions for holding the control system robust stability are analyzed, and thus, an intuitive determination method is provided based on the spectral radius criterion.

同时，对于实际中最常见的被控过程的加性和乘性不确定性，分析了控制系统保证鲁棒稳定性的充要条件，由此给出了基于谱半径判据的直观判定方法。

At the same time, sufficient and necessary conditions for holding the control system robust stability are analyzed in the presence of the process additive and multiplicative uncertainties often encountered in practice, and correspondingly, the on-line rule for tuning the adjustable parameters of the decoupling controller matrix is provided.

BZ said that everybody had to come at least once in their life for the Vipassana retreat. And everybody who had come said it was wonderful. Winnie even emphasized that once was not enough, and she wanted to stay on forever in the retreat! Oh, and Adeline said that the 10 days in the retreat were the most meaningful days in her life! Goodness, how could anyone enjoy such a life?!

槟中老师说，每个人一生至少也应该参加一次十日闭关，参加过的同学一个个说太棒了， Winnie 强调一生一次绝对不够，还说想永远呆下去， Adeline 则说这是她一生最快乐的10天……妈呀，怎么会有人享受这样的日子？！

She lives in a terrific apartment adjacent to us.
