They are particularly useful as general purpose research microspheres or spacer beads in a range of lower grade applications.

他们对多领域微球科学研究或的研究微球或次要间隔粒子的应用。

The graduated scale of emanations was as follows:(1) the creating spirit;(2) the directing spirit, or the world-soul;(3) primal matter;(4) active nature, a power proceeding from the world-soul;(5) the abstract body, also called secondary matter;(6) the world of the spheres;(7) the elements of the sublunary world; and (8) the world of minerals, plants, and animals composed of these elements.

The article discusses the basic principles of resource replacement at the beginning, that is, one resource has multi-purposes, and it can be divided as the important field, less important field and general field; the same need can be satisfied with different resources; related resources have cospecific field and independent field, and it can be divided as universal field, cospecific field, and independent field.

文章首先论述了资源替代的基本原理，即同种资源具有多种用途，可将其使用领域划分为重要领域、次要领域与一般领域；同时，同种需求可由不同的资源来满足。此外，资源的多用途性及满足同种用途资源多样化的特点，使相关资源之间在用途上存在共同的应用领域及独立应用领域，具体可将其分成资源的通用领域、共用领域和专用领域三种状况。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
