 Wang reiterated that the return of Chinese companies to Libya is linked to improved security situation, noting that Beijing will encourage Chinese companies to return as soon as Libya regains stability.

 This is much needed, because even though it upholds the principles of mutual respect, equality, mutual benefits and win-win results in providing foreign assistance, the lack of information about its aid has left room for suspicions to be raised about its motives. Some critics in the West accuse it of being a “rogue donor”, claiming it uses aid to support authoritarian regimes in return for access to their countries’ natural resources

 A research team, jointly led by Yan Xiyun from the Institute of Biophysics under the Chinese Academy of Sciences and Gao Lizeng from Yangzhou University, has for the first time developed a strategy to coordinate nanozymes to target tumor cells and selectively kill tumors. Their findings were published in Nature Communications last week.

 与英军现役“轻剑”导弹系统相比,FLAADS具有几大战术优势:首先,所有子系统都集成到一辆越野卡车底盘上,展开和撤收十分迅速,反应速度和机动能力远远超过“轻剑”。其次,该系统选择垂直发射方式,使导弹具备全向攻击能力,面对从刁钻角度飞来的目标都能“应对自如”。再次,系统所使用的“通用防空模块拦截弹”选用了主动雷达导引头,拦截弹发射后,完全可以“不用管”,地面武器系统可以“打了就跑”,系统生存性大大提高。更重要的是,FLAADS系统拥有双向数据链,使其具备发射后锁定和中途改变攻击目标的能力,专业术语叫“人在回路”,使得打击效能大大提升,反观英国陆军现役的“轻剑”导弹受无线电指令制导模式的限制,只能开火前锁定目标,并且中途无法改变攻击目标。如此丰富的先进技术集成,FLAADS的构造却极为洗练,能不要的设备都不要,系统组成非常简洁,无形中令部队维修保养更为便捷,同时也降低了全寿命使用费用。
