The microstructure and compositions of the spots on the blue colours of Jingdezhen Blue andWhite porcelain were investigated. The spots on the blue colours of Blue and White porcelainare the result of crystallization and enrichment of manganese and iron contained in cobalt bluepigment after high temperature sintering, and the compositions of the spots mainly depend on thecontents of manganese and iron in cobalt blue pigment.

通过对元代、明洪武及明宜德年间的景德镇青花瓷样品彩上斑点的显微结构和组成分析，研究了斑点的形成机理和组成，表明青花瓷彩上斑点是由青花钴料中的锰、铁、钴，经高温过程后，在釉熔体中的偏析所形成的，其物像组成，除主要取决于青花钴料中的锰、铁含量外，样品的胎、釉组成及烧成机制等也影响着铁的价态。

KL-SRF, woven as sleeving by the high glass fiber or special non-alkali glass fibers and coated with a thick cover of the iron oxide red / blue silicone, it can stop the melting iron splash and high-temperature and flames. It has a fire-retardant ,insulation, thermal insulation and anti-electricity.these features make it applicable to the protection of the cable and pipeline under the bad environment .

防火耐高温套管以高膨松性玻璃纤维或者特殊无碱玻璃纤维编织套管所制成，并覆以厚实的氧化铁红/蓝硅胶，其能阻挡熔铁喷溅，且不受高温和火焰所损坏，具有阻燃、隔热、保温、抗电、柔软等性能，这些特性使其适用于保护恶劣环境下的软管、缆线和管路。

He found that the coil was more effective when the solid iron core was replaced by a group of iron wires insulated from each other.

他发现线圈是更有效的当是固体铁质的核心是取代由一组铁电线绝缘对方的经验。

The alignment of the iron particles occurs because each of the iron filings becomes a miniature magnet with north and south poles.

铁粒子排列成线是由于每个铁屑都变成了一个拥有南极和北极的小型磁铁。

There were iron filings and iron powders deposited in the filters.

过滤器内淤积了铁屑和铁粉。

It consists of ten parallel cells containing a total of 914,000kg of iron filings, all purchased locally.(The iron lasts about two years before it has to be replaced.) Some 80% of the water treated is industrial discharge.

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。
