In order to eliminate the influence caused by the nonminimum phase characteristic of a common Boost DC/DC converter, Viswanathan K has proposed a novel tristate Boost DC/DC converter. For enhancing performance, the statespace averaging model of this converter was first presented in this paper. Due to the nonlinear nature in this model, an inputoutput feedback linearization technique was adopted, and a complete controllable linear system was obtained. Then a statefeedback control strategy was designed based on this linear system. Simulation results show that the proposed control strategy can assure constant output voltage in a wide range, so as to realize the stability of the system during large fluctuation of power supply and load disturbance. Good dynamic performance can also be achieved.
针对 Viswanathan K为消除普通BOOST DC/DC变换器的非最小相位特性而提出的三态Boost DC/DC变换器,为进一步提高这种电路拓扑的性能,在建立了变换器状态空间平均模型的基础上,针对其多变量、非线性特点,采用输入输出线性化将其转化为一个完全可控的线性系统,在此基础上应用现有成熟的线性控制策略进行了控制系统的设计,并且采用MATLAB进行仿真验证,结果表明:这种非线性控制策略可以确保输出电压在大范围内恒定可调,且即使存在大范围扰动(输入电压和负载变化均较大)的情况下,系统也可以确保稳定性和良好的动态性能。

Among these halls, the "Buddha Hall" demonstrates the artist's attempt most directly. In the Orient, artworks regarding religious themes usually will be presented with perfection and heavenliness, but such characteristics are not seen in Liu Dahong's work at all. Instead, the artist has calculatedly created chaos by placing parallel elements in his painting. Images of the frequently waged crusades in the history of the West, the horrifying witchcraft and the rigid statues of westerners have changed the Tibetan Buddha hall into a theater of the absurd. In the center an innocent girl struggling to get away from the stake is the most dramatic spectacle, and the giant, puppet-like Buddha along the people standing or sitting around constitute the scene of trial. In the backdrop, the landscapes and atrocities of wars often seen in western religious paintings are a keen contradiction to the people piously praying in the front. Their belief looks so hopeless.
佛堂是最具代表性的一件,在东方,宗教或描述宗教的艺术作品多倾向完美性和超世性的描写,但这些描写,在刘大鸿的佛堂中被完全破除,取代的是(刘大鸿此处以「置入」、「并列」为取代手法,达到了文本的交叉混乱,实为妙笔)西方宗教中频繁出现的宗教战争、巫术等负面形象,这些雕塑般的西方人物将西藏佛堂变化成荒诞舞台,画面中央一纯洁少女转身挣脱火刑的动作构成最强烈的力度焦点,众角色环状排列并点出审判的基本架构,且和背后如同宠物般拉扯的大佛形成呼应;佛堂后景重迭起西方宗教画内常见的风景描绘,黄土石间宗教战火连连,前景藏人和民众的诚心歌颂反而显出信仰的愚昧。

The calculating results which predict that the tip undercooling decreases continuously with an increase of the primary spacing and no minimum undercooling exists have lent an obvious evidence to the above theoretical analyses. The tip undercooling changes sharply for the low primary spacings but slowly for the large spacings.
本文提出的数值模型表明,Peclet数较小时,可以将强制性枝晶生长处理成自适应边界条件进行数值计算;计算结果充分证实了上述的理论分析,并指出顶部过冷随一次间距的增大而连续减小,不存在最小过冷值;一次间距较小时顶部过冷变化显著,较大时变化缓慢。

The characteristics of the filter include that the parameter variation ranges are taken into account, and within the parameter variation range each maximum magnitude of the residual vibrations is set to be equal. Thus, if the system parameters vary in lager ranges, the filter is more robust and the residual vibrations can be affectively eliminated.
该滤波器的特点是考虑了系统参数的变化范围,系统残留振动的最大幅值在参数变化区间内相等,从而提高了时滞滤波器的鲁棒性,特别是当系统参数大范围变化时,时滞滤波器有更强的鲁棒性,能有效消除柔性系统的残留振动。

The experimental results suggested that there were some rules during the fermentation as follows: pit temperature increased rapidly and then dropped at the beginning of the fermentation and kept stable eventually at 20~22 ℃; there was slight change in yellow water pH value at first and then pH value decreased gradually in middle fermentation stage and finally kept stable; the change rules of total acids of yellow water were opposite to pH change rules; the reducing sugar of yellow water increased at first and then dropped and kept stable eventually; there was almost no change in alcohol content of yellow water in prior fermentation period, and then it increased rapidly and dropped slowly and finally kept stable; gas production rate was as high as 550 L/d within the first week in fermentation and then dropped undulatingly and changed to zero or even negative gas production rate.
窖池温度在发酵前几天迅速升高,然后下降,最后趋于稳定,保持在20~22 ℃;黄水pH开始变化不大,中间逐渐下降,最后趋于稳定;黄水的总酸变化与pH相反;黄水中还原糖先升高后下降,最后基本保持稳定;黄水中酒精含量在发酵前期变化不大,后期先是迅速升高,然后缓慢下降,最后趋于稳定;在发酵前期一周内,产气量很大,最高达550 L/d;之后产气量呈波动式下降并逐渐平稳,最后趋于零甚至负产气量。

In the depth scope ranging from 1100 meters to 3500 meters, the direction of the middle principal stress becomes vertical.The simulation result, from the modelling of the Kun 2# drill and its vicinities, suggests that the vertical stress variation is relatively small in the place 3 to 7 times of the drill diameter from the well wall, but the horizontal stress varies in some trend. Moreover, the direction of the minimal stress component and the remote loading pressure take place large deviation in southeast direction.
