查询词典 concave function

Deep structure in the mantle concave or convex edge of mantle, Moho-discontinuity isobath or local turning control the regional metallogenic belt in distribution; major fault zones and their recombination region control the metallogenic zone; great fault depression, that is, overall depression in the context of uplift, that is, or local uplift in the background of overall fault depression, or the local stronger depression in the background of overall fault depression, all of these special structures are often the enriched areas of ore-forming elements and potential prospects.

深部构造，在幔凹或幔凸的边缘、莫霍面等深线密集或局部突出地段、扭曲端等控制区域成矿带的展布；大断裂带及其复合部位控制矿集区和大型矿床的产出；大断裂断陷构造，即隆中坳，或总体坳陷背景下的局部隆起，即坳中隆，或总体坳陷的背景下的局部更为强烈的坳陷，即坳中坳，所有这些特殊的构造部位，往往也是成矿元素的富集区和成矿远景区。

Self-buckled kerbstones consist of two different layers of compound cement. They are of many kinds of designs and colors. On the outer layer, there are illuminating materials made by special materials. The inner layers are made of common cement, so they are low in price. At the two ends of the kerbstone, there are concave and raised troughs for self-buckling. So they are convenient in installment. Different size of holes for draining water can be drilled according to actual situation.

自扣式侧石是由两层不同颗粒级配比的复合混凝土构成，具有多种图案和色彩，面层附有由特殊材料制作成的发光材料，内层为普通混凝土，成本低廉；侧石的两端有凹凸卡槽自扣连接，安装方便，不易沉降和倾斜；还可根据不同需要的距离可在不同位置上留有大小不同的排水孔，雨天能够及时排除路面积水，从而丰富花池，花坛及道路两侧绿化带水源。

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。
