The desiccants in common use have some shortcoming of themselves, in order to find substitutes and find a new way of processing the agriculture byproduct, in this paper, we prepared desiccant from corn hull. Corn hull has a great deal of surface hydroxyl that can form hydrogen bond with water molecule.

常用干燥剂在使用过程中存在着各自的缺点，为了寻找替代品，并寻找一条农副产品深加工利用的途径，在本文的研究中选择从玉米渣皮这种天然原料出发，利用其具有的大量表面羟基与水分子形成氢键的能力，将其制成干燥剂。

Therefore in ideal case, the hydrogen molecules will start to desorb from Ge-Ge dimers at a lower temperature, from Ge-Si dimers at a middle-high temperature, and from Si-Si dimers at a high temperature.

在理想状态下，在较低的加热温时氢分子应从Ge-Ge双原子单体开始脱附，在稍高的温度由Ge-Si脱附，在更高的温度才会由Si-Si脱附。

Under the same condition as methane partial oxidation, the reaction results are as follows: CH4 conversions is 88%, CO selectivity is 90%, H2 selectivity is 68%, CO2 selectivity is 12%.H2-TPD indicates that it is difficult for H2 to desorb from catalyst. It is estimated that the reaction between hydrogen and oxygen being absorbed is the primary approach to produce H2O, and it maybe lead to the lower H2 selectivity.

反应结果如下：CH4转化率88%；CO选择性90%；H2选择性68%，CO2选择性12%。H2-TPD实验表明，H2在催化剂表面难于脱附，表面氢与表面氧反应可能是生成H2O的主要途径，这也可能是H2选择性比较低的原因。

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。
