Development and Evaluation of a Spiral Disk Column System for High-speed Counter-current Chromatography 螺旋槽圆盘柱逆流色谱分离系统的研制及其应用评价
Application of spiral disk column in high-speed counter-current chromatography for peptide and protein separation 螺旋槽圆盘柱高速逆流色谱及其在多肽和蛋白分离中的应用
The utility model relates to a rotary-vane vacuum pump, which provides a column spiral torsional spring which is used for replacing a column spiral compressing spring. 本实用新型涉及旋片式真空泵,提供一种圆柱螺旋扭转弹簧,用它取代圆柱螺旋压缩弹簧。
Inquired into strictly the length calculation formula of round column component spiral hoop steel with its common errors, and figured out accurately the length coefficient of steel round column component spiral hoop based on combination fact situation of works. 针对目前长度计算公式的某些错误,进行了严密的理论推导并结合工程的实际情况,比较准确地给出钢筋混凝土圆柱形构件螺旋箍筋长度系数,从而更方便实际工程中的快速计算与应用。
Study on a type of reinforced bar transmitting force's joint of composite beam and continuous compound spiral hoop reinforced concrete column 连接钢筋传力的组合梁及连续复合螺旋箍混凝土柱节点的研究
In the process of civil engineering actions, calculation of the spiral hoop steel engineering quantity of column component, is closely related to the length of spiral hoop steel. 在土木工程活动中,常常要计算圆柱形构件螺旋箍筋的工程量,其工程量的正确计算与箍筋长度密切相关。
With spiral hoops strengthen column can raise transshape capacity of vertical reinforcement and concrete when the columns are destroying. 用绕丝加固柱可以提高柱破坏时纵筋和混凝土的应变。
The distinctive features of new long spiral drilling machine is the use of self-elevating column, and the column uses the truss structure replacing the original spiral steel cylinder structure. This structure can achieve vertical lift column and makes the process secure and reliable. 新型长螺旋钻机的显著特点是采用自升式立柱,该立柱采用桁架式结构,取代原有螺旋钢圆筒式结构,可以实现垂直起柱,因而起柱过程更加安全可靠。
