Very recently the existence of a charged state near the D-s(D) over bar*/D-s*(D) over bar threshold was predicted. This state, that we call Z(cs)(+), would be the strange partner of the recently observed Z(c)(+/-) (3900). Using standard techniques of QCD sum rules, we evaluate the three-point function for the vertices…

Cellulose has for a long time been used by man. It is renewable and an easily recyclable resource. Mostly it has been used in either its native form as wood or in the form of fibres. But in the early 1980s it was shown that it was possible to extract even smaller elements out of the fibres when wood pulp was subjected…

以丁铵黑药为捕收剂,添加一种新型抑制剂O,O-二(2,3-二羟基丙基)二硫代磷酸(DHDTP)对黄铜矿和方铅矿进行浮选,通过动电位和吸附量的测试,探讨抑制剂DHDTP与矿物的相互作用机理。浮选试验结果表明:在整个pH范围内,抑制剂DHDTP对黄铜矿的抑制作用很弱;在pH6~10范围内,抑制剂DHDTP对方铅矿有很强的抑制作用。随着抑制剂DHDTP用量的增多,方铅矿的回收率迅速降低,而黄铜矿的回收率只有小幅度的降低。在DHDTP用量278mg/L、矿浆pH6的条件下,人工混合矿浮选得出的精矿中铜的品位和回收率较好,分别为24.08%和81%。通过动电位和吸附量的测试结果可知,DHDTP在方铅矿上的吸附能力明显高于黄铜矿的。

将硼酸锌(ZB)添加膨胀阻燃聚丙烯体系(PP/IFR)中,利用热重分析仪(TGA)、X-射线荧光光谱仪(EDX)和红外光谱仪(FTIR)分析了该膨胀阻燃体系的热降解动力学和残炭的化学结构。结果表明,添加ZB后,PP/IFR体系提前分解,但保留了更多的残炭;EDX和FTIR分析结果表明,残炭中保留了更多的磷,且少量的ZB能促使IFR发生酯化反应,形成更多P-O-P和P-O-C的交联结构,从而提高材料的阻燃性能。
