In parallel installations , the larger valve handles the requirements for maximum flow down to its low flow capacity 这种并联安装方式中,大阀门处理降到低流量空穴下的最大流量需求。
Dopant - an element that contributes an electron or a hole to the conduction process , thus altering the conductivity 搀杂剂-可以为传导子电供提程过或空穴的元素,此元素可以改变传圆晶。
Dopant - an element that contributes an electron or a hole to the conduction process , thus altering the conductivity 搀杂剂-可以为传导过程提供电子或空穴的元素,此元素可以改变传导特性。
This makes the system of orbitals unstable and an electron from an orbital further out rapidly fills the hole 这使得轨道系统不稳定,外一层轨道的电子会迅速跃迁到内层空轨道上,填补空穴。
Design of the watts automatic control valve minimizes potential valve damage that can be caused by cavitation 美国瓦茨自动控制阀的结构将可能导致空穴现象的阀门损坏潜在危险降低到最小程度。
Stellar winds from clusters of newborn stars scattered throughout the cloud etched all the well - defined ridges and cavities 分布在整个星云中的新生恒星群发出的星风侵蚀出了清晰的隆起和空穴。
Logically enough , a genesis as turbulent as that of the emerald impedes the undisturbed formation of large , flawless crystals :充满液体的空穴,一些小气泡和一些小晶体。哥伦比亚的祖母绿则是典型的。
The sectional drawing illustrates the body cavities surrounding the plug . circulation is provided from the spaces above and below the plug 断面图说明环绕阀塞的阀体空穴。从阀塞上方和下方空间提供环流。
If flow requirements fall outside the capacity of a single valve , an additional smaller valve installed in parallel may be required 如果流量要求超出单个阀门的空穴区外,则可能需要并联安装一个较小的附属阀门。
