摘要：针对目前电缆组件中常用的半刚电缆组件焊接问题进行了对比分析研究,针对使用过程中经常出现电缆组件开裂、脱落及电性能达不到指标要求等问题,通过多次焊接试验,自行研制的焊接夹具满足设计指标要求。与传统焊接工艺方法比较,使用此种焊接方法可将半刚电缆组件的电压驻波比(VSWR)平均由原来的1.5提高到1.3;成品焊接合格率由原来的60%提高到90%以上。

摘要：鄂西北地区滑坡地质灾害发育丰富。根据滑坡分布发育特征,选取3个非连续变量和10个连续变量,从不同角度揭示鄂西北地区滑坡孕灾模式。基于3个非连续变量的统计分析,识别出四大类孕灾模式为:孕灾模式A(碎石土+志留系碎屑岩)、孕灾模式B(碎石土+武当群片岩)、孕灾模式C(岩质+顺向坡)、孕灾模式D(岩质+顺向斜交坡)。基于10个连续变量的敏感性分析,识别孕灾模式,结果表明:滑坡发育前缘高程主要集中在260~455 m高程段,且多为体积1.6~2.8×10~4m^3的小型滑坡,剖面上具有整体坡度14.4°~43.2°的特点,发育岩层倾角16°~28°。综合连续变量与非连续变量,获得区内滑坡的12类典型孕灾模式,为鄂西北地区滑坡区域孕灾机理研究提供参考。

摘要：Significant transient beam loading effects were observed during beam commissioning tests of prototype II of the injector for the accelerator driven sub-critical （ADS） system, which took place at the Institute of Modern Physics, Chinese Academy of Sciences, between October and December 2014. During these tests experiments were performed with continuous wave （CW） operation of the cavities with pulsed beam current, and the system was configured to make use of a prototype digital low level radio frequency （LLRF） controller. The system was originally operated in pulsed mode with a simple proportional plus integral and deviation （PID） feedback control algorithm, which was not able to maintain the desired gradient regulation during pulsed 10 mA beam operations. A unique simple transient beam loading compensation method which made use of a combination of proportional and integral （PI） feedback and feedforward control algorithm was implemented in order to significantly reduce the beam induced transient effect in the cavity gradients. The superconducting cavity field variation was reduced to less than 1.7% after turning on this control algorithm. The design and experimental results of this system are presented in this paper.

摘要：To test superconducting cavities, a vertical test system has been designed and set up at the Institute of Modern Physics （IMP）. The system design is based on VCO-PLL hardware and the NI Labview software. The test of the HWR010#2 superconducting cavity shows that the function of this test system is satisfactory for testing the low frequency cavity.

摘要：海底隧道长且竖井少,独头钻爆掘进距离长,施工通风问题突出。以青岛胶州湾第二海底隧道为依托,对钻爆法独头掘进施工的海域段隧道进行了压入式通风条件下掌子面附近风流流场、CO浓度场以及隧道内部粉尘扩散规律的研究。结果表明:根据掌子面处风速要求,风筒出风口距离掌子面40 m处是可行的;隧道通风后,涡流区域粉尘浓度分布不均,隧道风管一侧浓度明显大于另一侧,大部分粉尘在距离掌子面100 m内发生沉降和捕获;并根据CO浓度要求,确定了不同掘进距离和供风量情况下的进洞安全时间。
