查询词典 perlitic

Fresh perlitic rocks are found in the Jiutai area of the southeastern uplift of Songliao basin. In the perlitic rocks, phenocrysts are well preserved and they are mainly composed of plagioclase, biotite, amphibole, and mafic clinopyroxene and orthopyroxene.

在松辽盆地边缘东南隆起九台地区出露有比较新鲜的珍珠岩，内部斑晶保存完好，裂隙发育；斑晶矿物主要有斜长石、黑云母、角闪石，还有镁铁质的单斜辉石和斜方辉石。

The volcanic rocks of Early Cretaceous Yingcheng Formation contain abundant perlitic rocks and they are important petroliferous layers in Songliao basin.

松辽盆地早白垩世营城组火山岩系含有丰富的珍珠岩，为松辽盆地重要的油气勘探目的层位。

We conducted geochemical analyses on the perlitic rocks as well as vitreous rocks after removing phenoscrysts, and probe analyses on the phenocrysts.

对含斑晶珍珠岩和剔除斑晶后的珍珠岩玻璃质分别进行地球化学分析，斑晶矿物进行单矿物电子探针成分研究。

All these characteristics suggest that the perlitic rocks might have originated from upper crust, and their pyroxene xenocrysts may be the results of assimilation and contamination of wall rocks during the migration and ascent of magma.

这些特征表明，珍珠岩原岩可能来自于上部地壳，其辉石等捕虏晶为岩浆上侵运移过程与围岩发生混染作用的结果。

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

您可以鹬第二和第三工会领袖从这一立场出发。

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。
