A new high performance copper based alloy for electro‐mechanical connectors

The precipitation hardened high‐copper alloy CuNi1Co1Si (UNS design. C70350) was developed in two tempers in a high strength spring material for small connector devices. The combination of high strength, moderate conductivity, excellent thermal stability and good formability is explained by the microstructure of the strip material. In comparison to the nickel silicide hardened connector material CuNi3Si (C70250) the cobalt containing mixed silicides improve significantly strength. The weak anisotropy of the spring characteristics is explained by a process‐dependent texture. The good formability is calculated by FEM and proven by standardized bend test, as well as by manufacturing a demonstration part which is similar to a connector.

AMPS共聚物的合成及用于造纸废水絮凝处理的研究

主要研究了AMPS(2-丙烯酰胺基-2-甲基丙磺酸)共聚物的合成及应用。通过研究引发剂的用量、共聚单体的用量、EDTA用量、反应后期温度等因素对AM和AMPS共聚合反应的影响，发现在中性水溶液介质中，在氧化还原引发体系与偶氮类引发剂共同作用下，在5℃的低温下引发聚合反应，当引发剂用量为单体质量0．03％，反应后期温度为40℃时，可获得相对分子质量为1810万的AM和AMPS共聚物。并研究聚合氯化铝／AM和AMPS共聚物体系在造纸脱墨废水絮凝处理的应用，研究表明：AM和AMPS共聚物用量为0．75ms／L，与之复配的聚合氯化铝(PAC)最佳用量是100mg／L，其中1134万相对高分子质量的两性AMPS和AM、MAC共聚物效果更佳，与之复配的PAC用量可减少到75mg／L，CODCr去除率都达70％以上。

Landau–Zener Interferometry in a Cooper-Pair Box

In a driven system, a sequence of Landau–Zener transitions occur, and they may interfere with each other. We present experimental evidence of quantum interference effects in a superconducting charge qubit, a Cooper-pair box, where the LZ tunneling occurs at the charge degeneracy. By employing weak capacitive monitoring, we observe interference between consecutive LZ tunneling events.     

Study on phase retardation characteristic of LCVR using dispersion analysis and SVM

To calibrate the phase retardance of a Liquid crystal variable retarder(LCVR),its birefringence dispersion characteristic was analyzed,and the Support vector machines(SVM) algorithm was adopted to establish the prediction model.The obtained SVM decision function was used as a part of LCVR phase retardance,which was generated by the driving voltage.The experimental verification was carried out with a 568 nm laser.The results show that the deviation of the experimental value and the theoretical value is about 0.0061λ.SVM method could be used as an effective method for LCVR phase retardance characteristic calibration.
