CRM genome screeners screen sequences or complete genomes for CRMs as homotypic or heterotypic clusters of binding sites for any combination of transcription factors.

CRM基因组筛选器作为任何组合的转录因子的同型的或异型的结合位点类为CRMs筛选序列或全部基因组。

According to the velocity filed mentioned above, the contour of the drawing die was rationally designed. To prove its applicability and superiority, FEM software, MARC and SUPERFORM, were used to simulate the drawing process of cross tube in "conical die" and "streamlined die".

本文以十字形钢管为研究对象，开展对异型钢管拉拔成形过程研究，首先结合挤压流线理论，设计了&流线型&拉拔速度场模型，这为改善金属流动状态、降低能耗创造了良好条件；紧接着以&流线型&速度场为理论依据，对十字形管拉拔模具的凹模轮廓进行了合理设计。

This paper analyzes relationship among the design of plastic products, raw material constitution and fluid channel design of extrusion die and elucidates the importance of their a-greements each other.

论述了塑料制品设计、原料配方、设备选用与口模流道设计间的关系，阐明了它们之间良好协调的重要性；并结合塑料熔体流变理论和实践经验，以180装饰壁板为例，分析讨论了此类异型材口模流道设计的思路和方法

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。
