朝鲜官方媒体周四报道，朝鲜试射了一种“新设计的先进防空导弹系统”。
North Korea has tested a “newly-designed advanced air-defense missile system,” state media reported Thursday.
朝中社报道，中央军事委员会委员金正式大将周三指导了此次试射，旨在确认防空导弹系统的技术规格。这一确认是在韩国称平壤发射了多枚导弹的第二天发布的。
Gen. Kim Jong Sik, member of Central Military Commission, on Wednesday guided the test-fire which aimed at confirming technical specifications of the air-defense missile system, KCNA reported. The confirmation came a day after South Korea said Pyongyang had launched multiple missiles.
朝中社称：“试射证明了新材料和智能多制导模式的技术规格与可靠性，以及防空导弹系统的目标识别与跟踪能力及其探测信息处理装置。”
“The test-fire proved the technical specifications and reliability of the new material and intelligent multiple guided mode of the projectile, target identification and tracking capability of the air-defense missile system and its detection information processing device,” KCNA said.
报道补充说，同一天在另一次试验中，朝鲜东部地区的一支长程战略巡航导弹部队于周三“进行了火力打击演习示范”，但未具体说明地区。
In a separate test on the same day, a North Korean military long-range strategic cruise missile unit in the eastern area “gave a fire strike drill demonstration” on Wednesday, the report added without specifying the region.
报道补充道：“参加演习的分队完美完成了用长程战略巡航导弹打击虚拟机场目标的任务。”
“The sub-unit involved in the drill perfectly performed its mission to strike a virtual airport target with a long-range strategic cruise missile,” it added.
这是一周内第四次试射，此前平壤在上周四试射了600毫米“超精密”多管火箭炮。
This was fourth the time in a week, after Pyongyang fired of a 600-millimeter "ultra-precision" multiple rocket launcher last week Thursday.
朝鲜还在周六试射了挂载集束炸弹的战术弹道导弹，周一试射了战略巡航导弹的“扩散弹头”。
It also tested a cluster bomb mounted on tactical ballistic missiles Saturday and a "dispersal warhead" for a strategic cruise missile on Monday.
平壤接连进行导弹试射，正值韩美举行联合演习，以及朝韩半岛首尔与平壤之间紧张局势升级之际。
The back-to-back missile tests by Pyongyang comes amid joint drills held by South Korea and the US, as well as tensions on Korean Peninsula between Seoul and Pyongyang.
首尔指责平壤对9月21日非军事区内的爆炸事件负责，该事件导致三名韩国士兵受伤。
Seoul has blamed Pyongyang for an explosion inside Demilitarized Zone on Sept. 21, which wounded three South Korean soldiers.
朝鲜拒绝了这些指控，并未回应首尔恢复军事通讯以缓和紧张局势的提议。
North Korea has rejected accusations and has not responded to Seoul's offer of restoring military communication to ease tensions.
