剖面

When pump starts, the lower impeller lifts the solution up step by step. And the extreme centrifugal force from the enlarged higher impeller stops the solution as it entering the higher impellr. At the same time, the full solution in the chamber stops the air mixed with the solution in the chamber to go down. This way masterly eliminates both big problems of vertical sealless pump, overflow at high pressure and bubbles at big flow.

塑宝SV泵剖面结构SV Super Series Analytical cross section SV泵剖面结构泵开始运转时，底部叶轮将液体逐步上推，待液体进入上部叶轮时，即受加大之背叶的强大阻力而无法上升，但上部叶轮所卷入液体中的空气，却受阻於水室中贮满的液体而无法下降，如此巧妙地排除了立式无轴封泵高压时溢流，或大流量时吸入空气的两大难题。

A model of basic structure of the tectosphere and uniform layer in the study area is preliminarily constructed by using 3D Vp values with a grid of 1°×1°to the 400 km depth in Northeast China and selecting two representative sections perpendicular to each other and a structure model spectrum to the depth of the transition layer in the study area is depicted by using eight Vp value sections along different longitudes and latitudes.

利用东北地区1 1 深至400km的三维Vpkm/s）值数据，选择互相垂直的2条有代表性的剖面，初步建立研究区构造圈、均匀层基本结构模型；利用8套沿不同经纬线的剖面Vp值分布，勾绘出研究区深至过渡层的结构模型谱：进一步综合得到研究区三维岩石圈结构模型。

In modern researches on the grain-size characteristics of lake sediments, the methods of incertical dividing sediments grain-size have no rigorous mathematical theory to support. To resolve this omission, the case of pollen zonation was taken for reference. 338 samples measured by Mastersizer 2000 from DG02 core of Gahai lake in Qaidam Basin were studied. Considering the clustering results of sequential clusters did not change the sequence of samples, tilia software package was used to divide the dividing sediments grain-size.

针对现阶段湖泊沉积物粒度特征研究中垂直剖面分层方法所存在的数学方法的不足，借鉴孢粉分带比较成熟的案例，应用有序聚类法中次序不变的特点，以柴达木盆地尕海湖DG02钻孔338个经激光粒度仪测试的样品为研究对象，在有序聚类的数学理论基础上，借助Tilia软件将湖泊沉积物垂直剖面进行分层。
