It was composed of 75% silver and 25% copper, had a six-pointed star on one side, a Roman numeral III on the other, and — weighing in at four-fifths of a gram — was the lightest coin ever produced by the US Mint. The silver three cent piece was discontinued by the Coinage Act of 1873; at that time, a three cent nickel coin was issued, made up of copper and nickel and slightly larger than the silver version.

改硬币是由75%的银和25%的铜铸造，图案的一面有一个六角星，另一面是罗马数字III，重量只有1克的5分之4 -这枚硬币是美国造币厂有史以来发行的最轻的硬币。1873年通过的《硬币法案》，停用了这种硬币；与此同时发行了由铜和镍铸造的3美分镍币，这种硬币比银版硬币略大一些。

You can snipe the second and third union leaders from this position.

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。
