In an earlier article I wrote about the ivory tower bias of Chinese higher education, with the assumption that a university education means you never have to get your hands dirty. This has led to automotive engineers who have never driven a car and coal mine engineers who have never been in a mine (see BusinessWeek.com, 7/31/06,"Chindia's Workforce Worries").

以前我曾写过文章批评中国高等教育体系中存在的象牙塔式思维，这种思维认为拿到大学文凭就不用再干脏活累活了，结果出现的现象是自动化工程师不会开车，煤矿工程师从没下过煤矿（见BusinessWeek.com， 7/31/06，&Chindia's Workforce Worries&）。

Based on low frequency drive system of the DPB550/150 Ⅱ type an intelligent control strategy applied to the speed control of AC mine hoist is described and a satisfactory control performance is obtained. Some problems, such as unsatisfactory control performance of AC coal mine hoist in deceleration and low speed drive period, and the difficulty of obtaining the constant deceleration during changing load, are solved.

以DPB－550／150－I型中国矿业大学低频拖动系统为基础，应用智能控制策略，实现了交流提升机的速度控制，得到了较好的恒减速控制性能，解决了矿井交流提升机在减速段和爬行段的速度控制性能较差以及在负载变动时，很难实现恒减速的问题。

The State Department exercised the minerals property rights and the mine management enterprise on behalf of the country exercises the mining power to form a void region, under the unclear situation of property right restraint, the coal mine operator reduces the security cost and carries on plundering mining to the mineral resource, which caused the safety production in great danger.

国务院代表国家行使矿产所有权与矿山经营企业行使采矿权形成了一个虚空地带，在产权约束不明的情况之下，煤矿经营者降低安全成本并对矿产资源进行掠夺性开采，致使安全生产岌岌可危。

In this paper, different coal face 3801 in a mine gas emission time is based on gray theory of gas emission prediction method, a mine gas emission in GM (1, 1) prediction model made its prediction of gas emission, by making the residual test, the results show that the prediction accuracy can be predicted.

本文以某矿3801采煤工作面不同时间段瓦斯涌出量为依据，运用灰色理论提出了瓦斯涌出量的预测方法，建立了矿井瓦斯涌出量的GM(1 ，1)预测模型，并对其进行了瓦斯涌出量的预测，通过进行残差检验，结果表明预测精度高，可以进行预测。

Fourth, focus on safety in production, especially coal mine production safety, production safety law and binding on the mine safety law enforcement checks.

第四，着眼于安全生产，特别是煤矿安全生产，安全生产的法律和有约束力的关于煤矿安全执法检查。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
