与制颗粒相比较，膨化的高温调质引起关注的主要问题是对营养的破坏，特别是酶、维生素、氨基酸和直接饲喂的微生物，通过日粮强化或敏感营养制粒后添加可以解决这些问题。

Albicans strains with fluconazole. Method: A series of 16 strains C. albicans from the same body were induced to form pseudo-hyphae in RPMI 1640 medium and DMEM medium at 37 癈 for twenty-four hours respectively. The pseudo-hyphae and yeast were counted and the ratio between pseudo-hypha and total cells was calculated. C. albicans strains were induced to form pseudo-hyphae in RPMI 1640 medium for seven days by transferring twelve times. The genome DNAs of the hyphal-form of C. albicans was cleaved by two restriction enzymes EcoR I and Bgl II, the products were electrophored and photoed.

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。
