Nevertheless, the fructification of Hao of green cloth with soft nap and the papaverous fruit that abstract opium very elephant, on taxology, hao of green cloth with soft nap is belonged to and opium poppy is belonged to be attributed to papaverous division plant together.

不过，绿绒蒿的果实与提炼鸦片的罂粟果很象，在分类学上，绿绒蒿属和罂粟属同归于罂粟科植物。

The possible reason is that doped Zr〓 ion enters the interstitial sites for its small ionic radius and no dipole complexes were formed. Monovalent ion F〓 has been reported to improve the scintillating performance greatly. Our results show that Agrand diagrams of F〓: PWO crystals obey an modified Cole-Cole equation. The crystals present similar dielectric relaxation phenomena to but have much higher activation energy than that of RE〓: PWO crystals, which originate from the 〓 dipole complexes. The co-doping of trivalent Y〓 and pentavalent ion Nb〓 does not always show a better scintillation performance than that of solely doped samples, which could be attributed to the existence of the 〓 dipole complexes, which counteract the solely doping effect.

而Zr〓由于离子半径太小，可能进入间隙位置，不形成类似的偶极缺陷；一价负离子F〓的掺入提高了晶体闪烁性能，阻抗谱测试结果表明F〓：PWO晶体Argand图符合修正的Cole—Cole方程，晶体同样表现出介电弛豫现象，并具有比RE〓：PWO晶体中高得多的弛豫激活能，可能起源于形成的〓偶极缺陷；Y〓和Nb〓双掺的PWO晶体并没有显示出两种离子单掺优点的叠加，阻抗谱测量结果表明，在双掺晶体中可能形成〓偶极缺陷，使两者掺杂作用相互抵消。

Cutaneous disorders attributed to sebaceous glands, such as acne vulgaris, are really disorders of the entire pilosebaceous unit.

与皮脂腺有关的皮肤病，如寻常性痤疮实际上是整个毛囊皮脂腺单位的疾病。

On a larger scale, the astronomical theory of orbital influences was revived circa 1976, and climate variation attributed to such factors as ENSO, the Pacific Decadal Oscillation, and solar activity are now being widely discussed. Still, more than 50 years later, scientists agree that the uncontrolled experiment pointed out by Plass in 1956 has been verified, and a warmer future caused by the radiative effects of CO2 is in store.

从更大的范围看，地球轨道影响气候的&天文说&在1976年前后再度流行，厄尔尼诺南徊、太平洋年代际振荡、太阳活动等因素引起的气候变化正在被广泛地讨论。50多年过去了，科学家认为普拉斯在1956年所说的&无节制的实验&得到了证实，CO2的辐射效应造成的更温暖的未来即将到来。

The favorable environment can be attributed to improvements in economic fundamentals in emerging markets, a reduction in external borrowing requirements, the abundant global liquidity that has allowed many sovereigns to prefinance their 2005 external financing needs, and more reliance on domestic capital markets.

形成有利环境的原因是，新兴市场经济体的基本要素得到了改善，外部借贷要求有所减少，充裕的全球流动性－－它让许多主权国家预先得到他们2005年通过外部融资所需要的资金，以及更多依靠国内资本市场等。

The favorable environment can be attributed to improvements in economic fundamentals in emerging markets, a reduction in external borrowing requirements, the abundant global liquidity that has allowed many sovereigns to prefinance their 2005 external financing needs, and more reliance on domestic capital markets.

许多新兴市场国家经济的基本要素正在不断改善－－包括加强他们政策框架可信性和债务结构质量的工作－－已经使主权信贷等级得到一系列提升，有助于形成良性的金融市场环境。关键词：金融稳定，私人部门，利率政策，通货紧缩，流动性，资本市场在过去的两年里，新兴市场主权债务国享受到了大为改善的金融环境。

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。
