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).

激光脉冲沉积（PLD)简介
脉冲激光沉积 （Pulsed laser deposition），就是将激光聚焦于靶材上一个较小的面积，利用激光的高能量密度将部分靶材料蒸发甚至电离，使其能够脱离靶材而向基底运动，进而在基底上沉积，从而形成薄膜的一种方式。 在众多的薄膜制备方法中，脉冲激光沉积技术的应用最为广泛，可用来制备金属、

激光脉冲沉积（PLD)的机制
PLD的系统设备简单，相反，它的原理却是非常复杂的物理现象。它涉及高能量脉冲辐射冲击固体靶时，激光与物质之间的所有物理相互作用，亦包括等离子羽状物的形成，其后已熔化的物质通过等离子羽状物到达已加热的基片表面的转移，及最后的膜生成过程。所以，PLD一般可以分为以下四个阶段： 1. 激光辐射与靶的
激光脉冲沉积（PLD)的优点
1. 易获得期望化学计量比的多组分薄膜，即具有良好的保成分性； 2. 沉积速率高，试验周期短，衬底温度要求低，制备的薄膜均匀； 3. 工艺参数任意调节，对靶材的种类没有限制； 4. 发展潜力巨大，具有极大的兼容性； 5. 便于清洁处理，可以制备多种薄膜材料。

激光脉冲沉积（PLD)的历史背景
早于1916年，爱因斯坦（Albert Einstein）已提出受激发射作用的假设。可是，首次以红宝石棒为产生激光媒介的激光器，却要到1960年，才由梅曼（Theodore H. Maiman）在休斯实验研究所建造出来。总共相隔了44年。使用激光来熔化物料的历史，要追溯到1962年，布里奇（Br
激光脉冲沉积（PLD)的发展前景

什么是水活度（Water－Activity）
水活度被定义为当前可用“自由水”的量，和水分含量没有直接的对比关系，水活度值范围在0(绝对干燥)和1（100%相对湿度）之间。当物质与环境空气发生水分交换活动会在表面形成对微生物生长的理想条件，这样会影响微生物的稳定性。水活度同时也是影响食品中化学反应的重要因素。
