| 1 | 多壁碳纳米管白水泥复合材料力学性能与电学性能试验研究显示文摘将多壁碳纳米管(MWCNTs)按照一定比例掺入到白水泥净浆和白水泥砂浆中,对MWCNTs水泥基复合材料的抗压强度、不同频率下电阻特性和微观结构进行试验研究,试验结果表明:MWCNTs白水泥净浆和白水泥砂浆的抗压强度随着MWCNTs掺入量的增加,先提高,而后降低,当MWCNTs掺量为0.3wt%时,白水泥净浆和砂浆的抗压强度改善效果最明显;不同MWCNTs掺量的白水泥净浆和白水泥砂浆的电阻率均随着测试频率的升高而降低,并且低频时电阻率随频率降低的速度较慢,而高频时电阻率随频率降低的速率较快;MWCNTs白水泥净浆和MWCNTs白水泥砂浆的电阻率,均随MWCNTs掺入量的增高而降低;MWCNTs白水泥净浆和MWCNTs白水泥砂浆的电阻率均随着龄期的增加而增加。 | 黎恒杆 王玉林 罗昊 林丹萍 班远付 Ghimire Prateek 苏晴微 林姝彦 | 2019 | 硅酸盐通报2019，38，9： | 9 |
| 2 | Thermal decomposition and kinetics of plastic bonded explosives based on mixture of HMX and TATB with polymer matrices显示文摘This work describes thermal decomposition behaviour of plastic bonded explosives(PBXs) based on mixture of 1,3,5,7-tetranitro-1,3,5,7-tetrazocane(HMX) and 2,4,6-triamino-1,3,5-trinitrobenzene(TATB)with Viton A as polymer binder. Thermal decomposition of PBXs was undertaken by applying simultaneous thermal analysis(STA) and differential scanning calorimetry(DSC) to investigate influence of the HMX amount on thermal behavior and its kinetics. Thermogravimetric analysis(TGA) indicated that the thermal decomposition of PBXs based on mixture of HMX and TATB was occurred in a three-steps. The first step was mainly due to decomposition of HMX. The second step was ascribed due to decomposition of TATB, while the third step was occurred due to decomposition of the polymer matrices. The thermal decomposition % was increased with increasing HMX amount. The kinetics related to thermal decomposition were investigated under non-isothermal for a single heating rate measurement. The variation in the activation energy of PBXs based on mixture of HMX and TATB was observed with varying the HMX amount. The kinetics from the results of TGA data at various heating rates under non-isothermal conditions were also calculated by Flynn—Wall—Ozawa(FWO) and Kissinger-Akahira-Sunose(KAS)methods. The activation energies calculated by employing FWO method were very close to those obtained by KAS method. The mean activation energy calculated by FWO and KAS methods was also a good agreement with the activation energy obtained from single heating rate measurement in the first step decomposition. | Arjun Singh Tirupati C.Sharma Mahesh Kumar Jaspreet Kaur Narang Prateek Kishore Alok Srivastava | 2017 | Defence Technology(防务技术)2017，13，1： | 8 |
| 3 | 多壁碳纳米管的分散效果对水泥净浆电学和力学性能的影响研究显示文摘研究分散处理后的多壁碳纳米管对水泥净浆材料的电学性能和力学性能影响。试验结果表明:多壁碳纳米管水泥净浆材料的电阻率随着测试频率的升高而降低,随养护时间的增长而增大。当多壁碳纳米管分散均匀时,电阻率随掺量的增加而减小,两者呈良好的相关性;当分散不均匀时,电阻率随多壁碳纳米管掺量变化不确定,呈现离散性。在低掺量条件下,当多壁碳纳米管在水泥净浆分散均匀时,多壁碳纳米管能提高水泥净浆的抗压强度和抗折强度,且提高幅度随多壁碳纳米管掺量增加而增大;而当多壁碳纳米管分散不均匀时,掺入多壁碳纳米管会削弱水泥净浆的抗折强度和抗压强度,其力学性能与多壁碳纳米管掺入量之间关系呈不确定性。 | 黎恒杆 王玉林 林丹萍 苏晴微 林姝彦 潘正阳 杨竞龙 Ghimire Prateek 朱德良 | 2019 | 工业建筑2019，49，10： | 8 |
| 4 | 多壁碳纳米管分散性对水泥基材料导电性能和电热特性的影响显示文摘采用分散剂、超声处理及离心机分离作用,得到分散均匀、稳定状态的多壁碳纳米管(MWCNTs)悬浮液和分散不均匀、团簇状态的MWCNTs沉淀,分别将这两种状态的MWCNTs掺入水泥净浆中,研究MWCNTs分散性对水泥基材料电学性能和电热特性的影响。结果表明:MWCNTs在水泥基体中分散均匀时,随MWCNTs掺量的增加试块电阻率下降;当MWCNTs在水泥基体中分散不均匀时,试块的导电性与MWCNTs掺量没有明确的相关性。MWCNTs水泥净浆的电阻率均随测试温度的升高不断降低,当温度超过80℃时,电阻率趋于恒定,并且MWCNTs分散均匀时,水泥净浆电阻率受温度影响的程度随MWCNTs掺量增高而减小;MWCNTs在基体中分散效果好时,水泥净浆因通电引起的升温速率和幅度随着MWCNTs掺量增大而提高。 | 黎恒杆 王玉林 罗昊 Ghimire Prateek 林姝彦 潘正阳 杨竞龙 苏晴微 | 2020 | 硅酸盐通报2020，39，11： | 4 |

| 6 | Strategic planning and designing of a hospital disaster manual in a tertiary care, teaching, research and referral institute in India显示文摘BACKGROUND: As per the 'Disaster Management Act, 2005' of India, it is mandatory for government hospitals in India to prepare a disaster plan. This study aimed to prepare a disaster manual of a 1 900 bed tertiary care hospital, in consultation and involvement of all concerned stakeholders.METHODS: A committee of members from hospital administration, clinical, diagnostic and supportive departments worked on an initial document prepared according to the Act and gave their inputs to frame a final disaster manual.RESULTS: The prepared departmental standard operating procedures involved 116 people(doctors and paramedical staff), and were then synchronized, in 12 committee meetings, to produce the final hospital disaster manual.CONCLUSIONS: The present disaster manual is one of the few comprehensive plans prepared by the stakeholders of a government hospital in India, who themselves form a part of the disaster response team. It also helped in co-ordinated conduction of mock drills. | Shweta Talati Prateek Bhatia Ashok Kumar A.K.Gupta Col.D Ojha | 2014 | World Journal of Emergency Medicine2014，5，1： | 3 |
