A process for partial conversion and low-temp transform of CO in the synthetic ammonia plant where coal is used to generate gas features that the Fe-Mo catalyst for partial conversion of CO, anti-poisoning agent and Co-Mo catalyst for low-temp conversion are used and the temp of semi-water gas is controlled to 200-260 deg.C at entering anti-poisoning layer, and 150-250 deg.C at the segments of said Co-Mo catalyst layer, and lower than 300 deg.C at bed layer to prevent high-temp reversal of sulfurizing reaction and make the catalyst activity optimal. Its advantages are long service life of catalyst, low system resistance, saving energy and convenient operation.

本发明是中小合成氨厂以一种CO部分转化抗毒保护层配低温变换的工艺，涉及煤造气合成氨厂0.6～2.0MPa半水煤气变换工艺流程，该工艺用铁－钼CO部分转化催化剂、抗毒剂，配钴－钼低变催化剂，半水煤气进入部分转化抗毒层温度为200～260℃，进钴－钼低变催化剂各段温度为150～250℃，床层温度控制在300℃以内，避免高温下反硫化反应发生，保护催化剂活性处最佳状态，寿命延长、系统阻力小、节汽、节电，具有比其他变换工艺更好地节能效果，操作方便，有效生产时间长，经济效益显著等特点。

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。
