Cone - shaped bayonet ring couplings for rolling stock part 18 : columned thread straight coupling bodies 机车车辆用锥面卡套式管接头.第18部分:管柱直通管接头体
An analytic solution for post - buckling of tubularssubjected to axial and torsional loading inhorizontal circular cylinders 水平圆管中受压扭作用管柱屈曲后的解析解
Switch on the vacuum to draw the solution through the column ( the plasmid dna binds to the column material ) 开启真空装置使液体通过管柱(质体dna会与管柱物质结合) 。
All gas vented during the snubbing / stripping operation must be flared and burned a minimum of 50m from the well 要在离井口至少50米开外点着并燃烧承压起下管柱操作过程中排出的气体。
The main products of sacsc are the automobile combination switches with brand “ zhuifeng ” and the steering column 沈阳市汽车开关厂的主导产品是“追风”牌汽车组合开关和方向机转向管柱。
Due to the maximum end capping , stability of the packing material is much improved over other commercially available c18 columns 因为高度之终结处理,充填材料之稳定度较其他市面上之管柱为佳。
Each certificate of analysis lists the physical properties of the packing material and the test chromatogram demonstrating the column s efficiency 每一成分分析表列出充填材料之物理性质,而测试层析图显示管柱的效能。
Now kanto gives you the ability to separate all substances , even if they are hydrophilic or hydrophobic , through the use of mightysil columns 现在关东化学使您可藉由mightysil管柱分离所有的物质,不论是亲水性或厌水性物质。
Mightysil gp is a versatile , highly reliable hplc column designed for use with a variety of samples having a wide ph range from acidic to basic Mightysil gp为一用途广泛,且具高信赖度之管柱,可用于分析多种具备广泛酸硷值之样品。
Rp - 8 gp and rp - 4 gp columns are for use with highly hydrophobic samples and bring faster elution in a lower consumption of organic solvent 除了rp - 18管柱针对高厌水性物质使用外, rp - 8 c8及rp - 4 c4管柱可使冲提较快且有机溶剂之消?较少。
