    噴射發動機自二戰後已成為飛機主要動力來源,其中渦輪噴射發動機為當時主流。但因油耗及次音速性能不佳,在民用市場很快的被渦輪扇發動機取代。又軍用發動機有超音速巡航之需求及油耗考量,也漸採用低旁通比之渦輪扇發動機。航空用發動機於流場設計、機體結構、材料及相關製造能力上要求較高,因此極少國家有能力自行開發研製。本文針對目前各國渦輪扇發動機發展概況及材料發展趨勢,探討其核心技術發展趨勢。Jet engine has become the main source of aircraft power after World War II, and the turbojet engine is the most commonly used version. Due to deficiency of fuel consumption and performance under subsonic conditions, turbojets were being gradually substituted by turbofan engines in civil aerospace, and they're turning to those with low bypass ratios for military aircraft engines to meet the requirements of fuel efficiency in supersonic cruise. However, the capacities have been highly requested for the flow field analysis, materials and structural design, and related manufacturing of turbofan engines that few countries by their own independent development. This paper is to discuss the trends focusing on the materials and core technology of world's turbofan engines.

    火工延遲經常被應用在軍事與商業,主要是利用時間延遲來區隔兩起能量作用,例如:軍用手榴彈中所使用之延期管,其延期藥組成均包含鋇、鉛、鉻酸鹽以及過氯酸鹽等危害性物質,因此美國陸軍自1997年起持續地調整延期藥組成[1],企圖將危害環境物質從延期藥配方中移除。本文所描述之三種新型綠色延期藥組成-坽Si/Bi2O3/Sb2O3[2-3];夌B4C/NaIO4/PTFE[4-5];奅Ti/C-Ni/Al-Al2O3[6],其特點為組成對環境友善且延期時間容易調整,不會因延期管殼之高熱導性造成延期藥於燃燒傳遞期間大量熱損失而導致傳火中斷。Pyrotechnic delays are commonly used in military and commercial applications mainly for delaying the reaction between two energetic events, for example, using delay tube to prolong the grenade explosion. Generally, formulation of delay contains barium, lead, chromates, and perchlorates, which are hazardous to the environment. To that end, the US Army has successively reformulated pyrotechnic items by removing those materials since 1997. This paper describes three new types of environment-friendly green materials composed of Si/Bi2O3, B4C/NaIO4/PTFE, and Ti/C-Ni/Al-Al2O3, which are capable of tunable explosion, continuous reaction in delay tubes, and no tremendous heat losses due to delay that can result in quenching.

    Mode-S為新一代二次監視雷達(Secondary Surveillance Radar, SSR)系統[1],透過選址詢問(Roll Call)有效降低傳統二次監視雷達之全呼叫詢問(All Call)產生大量的同步干擾(Garble)和非同步干擾(Fruit)。隨著航空交通需求以及密度的增加,為實現高效能選址詢問,本文提出目標追蹤及目標排程等兩項關鍵技術。在目標追蹤關鍵技術,本文提出自適應常增益卡爾曼追蹤器(Adaptive Constant Gain Kalman Tracker)設計,修正卡爾曼濾波器(Kalman Filter)[2]增益計算方式,降低運算複雜度,並且隨目標的運動變量自適應調整追蹤器參數,實現多目標即時追蹤。

    早期原油開採的輕油裂解與煉油過程中,會在不同階段產出各種化學品,作為汽柴油、燃料油及石化品原料。我國經歷了數十年的努力,政府與民間企業建構了強大的石化工業,除了奠立民生用品的產業鏈之外,也經由外銷貢獻了龐大的外匯儲備。但是在傳統煉油產品中,含五個碳與含九個碳的化學品因為產量限制,並未完全被利用到,而且此兩種原料化學品有相當大比例被轉製成汽柴油銷售,相對價值較低。

    由於登革熱為法定傳染病,且目前國內醫療單位常使用試紙或試劑對疑似感染登革熱之患者進行快速篩檢,每次檢測費用約新台幣300元,惟試紙或試劑快篩無法鑑定感染之登革熱型別,需將患者檢體送交具有專業人員與檢測設備之實驗室進行檢驗,且一般約需花費2~3天之時間方可確定患者感染之登革熱型別,易形成防疫漏洞。因此,國防醫學院預防醫學研究所則向國家中山科學研究院系統製造中心(以下簡稱本中心)提出共同研製登革熱生物晶片快速檢測系統之需求,以期裨益解決日益增加之檢測需求,更有助於準確檢驗患者感染之登革熱病毒型別,輔助醫療人員正確用藥,提高治癒率。此外,國防醫學院預防醫學研究所於106年6月與本中心簽署合作意願書共同開發軍民通用型之登革熱生物晶片快速檢測系統,以期未來可應用於防疫任務。
