MeasuringPLDActivityInVivo
Phospholipase D (PLD) hydrolyzes structural phospholipids like phosphatidylcholine (PC) and phosphatidylethanolamine (PE) into phosphatidic acid (PA) and free choline/ethanolamine. In plants, this activity can be stimulated by a wide variety of biotic and abiotic stresses (Li et al., Biochim Biophys Acta 1791:927–935, 2009; Testerink and Munnik, J Exp Bot 62(7):2349–2361, 2011).

激光脈沖沉積（PLD)簡介
脈沖激光沉積 （Pulsed laser deposition），就是將激光聚焦于靶材上一個較小的面積，利用激光的高能量密度將部分靶材料蒸發甚至電離，使其能夠脫離靶材而向基底運動，進而在基底上沉積，從而形成薄膜的一種方式。 在眾多的薄膜制備方法中，脈沖激光沉積技術的應用最為廣泛，可用來制備金屬、

激光脈沖沉積（PLD)的機制
PLD的系統設備簡單，相反，它的原理卻是非常復雜的物理現象。它涉及高能量脈沖輻射沖擊固體靶時，激光與物質之間的所有物理相互作用，亦包括等離子羽狀物的形成，其后已熔化的物質通過等離子羽狀物到達已加熱的基片表面的轉移，及最后的膜生成過程。所以，PLD一般可以分為以下四個階段： 1. 激光輻射與靶的
激光脈沖沉積（PLD)的優點
1. 易獲得期望化學計量比的多組分薄膜，即具有良好的保成分性； 2. 沉積速率高，試驗周期短，襯底溫度要求低，制備的薄膜均勻； 3. 工藝參數任意調節，對靶材的種類沒有限制； 4. 發展潛力巨大，具有極大的兼容性； 5. 便于清潔處理，可以制備多種薄膜材料。

激光脈沖沉積（PLD)的歷史背景
早于1916年，愛因斯坦（Albert Einstein）已提出受激發射作用的假設。可是，首次以紅寶石棒為產生激光媒介的激光器，卻要到1960年，才由梅曼（Theodore H. Maiman）在休斯實驗研究所建造出來。總共相隔了44年。使用激光來熔化物料的歷史，要追溯到1962年，布里奇（Br
激光脈沖沉積（PLD)的發展前景
由脈沖激光沉積技術的原理、特點可知，它是一種極具發展潛力的薄膜制備技術。隨著輔助設備和工藝的進一步優化，將在半導體薄膜、超晶格、超導、生物涂層等功能薄膜的制備方面發揮重要的作用；并能加快薄膜生長機理的研究和提高薄膜的應用水平，加速材料科學和凝聚態物理學的研究進程。同時也為新型薄膜的制備提供了一種

什么是水活度（Water－Activity）
水活度被定義為當前可用“自由水”的量，和水分含量沒有直接的對比關系，水活度值范圍在0(絕對干燥)和1（100%相對濕度）之間。當物質與環境空氣發生水分交換活動會在表面形成對微生物生長的理想條件，這樣會影響微生物的穩定性。水活度同時也是影響食品中化學反應的重要因素。
