On the basis of analysing the mine production and haulage System the basic concepts and calculating methods for the reliability degree of mine production and haulage system are put forward The mathematical models for assigning the reliability degree and deigning the system are established in this paper .

本文在分析矿井生产运输系统的基础上，提出了矿井生产运输系统可靠度的基本概念及其计算方法，建立了可靠度最优分配的数学模型及最优生产运输系统可靠性设计的数学模型

The results show that: 1. In the selected four funds, the theoretical risk of three funds is less than that of the actual portfolio fund, and only one fund's risk is higher than that of the actual portfolio fund; 2. It's hard to determine which combination is better between the single exponential model and Markowits'model;.3. Allowing short-selling is better than disallowing short-selling and the optimal solution can not be found under the condition of disallowing short-selling.

结果发现：(1)4只基金中有3只基金的理论模型的风险小于基金实际组合的风险，1只基金的理论模型的风险大于基金实际组合的风险；(2)单指数模型组合与Markowitz模型组合熟优熟劣难以定论；(3)允许卖空组合优于非允许卖空组合，且非允许卖空使得理论模型有时找不到最优解。

Integrating the linear quadratic regulator carol theory and integral sliding mode control, a global robust optimal eliding mode control strategy was proposed for the brushless DC motors.

针对无刷直流电动机伺服系统，将线性二次型最优调节器控制理论与积分滑模控制相结合，提出了一种全局鲁棒最优滑模控制器的设计方法。

By using all of the above actions, the best benefits can finally be perused. For most of construction enterprises that have the funds problem, to clear up the old debt is their first step, so as to making full use of the funds and guarantee the enterprise's strength. The enterprise with powerful strength will have more opportunities to choose the superior projects, which has a comparative advantage on the cost control and a well credit standing on the recycling of the project funds. Then more funds the enterprise will have and the strength is powered at the same time. On this benign circle, the enterprise's benefit is surly guarantied. What's more, it will set up a bright flag in the comparatively confused construction profession market.

对于大多数被资金困扰的建筑施工企业而言，清理旧帐是第1步，用活资金，保证实力；实力有了，就有更多的机会选择质优工程；对于质优工程，成本相对来说比较好控制，而且工程款的回收也有保障；然后就有更多的资金，更好的实力……在企业实现自身良性循环的同时，效益当然有保障，更重要的是给相对比较混乱的建筑施工行业市场树立1面鲜明的旗帜。
