  5. Tem was used to consecutively investigate the size and appearance of dibasic lead phosphite in the reaction process. it found that nanocrystal grain of lead oxide phosphite hydrate had favorite direction in the mlps method, many nanocrystal grain in near area would aggregate and assembled as nanowire, the diameter of the nanowire was about a crystal grain size and the length of nanowire could reach hundreds of nanometers, then they would gather to needle or bar like particles

    利用tem對二鹽基亞磷酸鉛在反應過程中粒子的大小、形貌進行跟蹤觀察，並記錄下三個時間下的微粒照片，發現用微液相合成法制備的二鹽基亞磷酸鉛晶粒在生長團聚時存在取向規律，同一區域的晶粒會長成一條納米線，直徑有一個晶粒的大小，長度可以達到幾百nm 。
  6. The eutectic crystal al3fe often is " needle " shape or short line shape but the shape of primary crystal al3fe is relative to the adding amount of fe powder and the temperature of heat preservation stirring. while the adding amount of pure fe powder is few and the temperature of heat preservation stirring is higher than the temperature of liquidus of al - fe binary alloys equilibrium phase diagram, the reaction synthetical primary crystal al3fe exhibits short worm shape

    加入量少，保溫攪拌溫度在al - fe二元合金液相線以上，則形成的初晶al _ 3fe呈短蠕蟲狀； fe加入量大，保溫溫度在液相線以上，初晶al _ 3fe以平面方式生長，復合材料中的初晶al _ 3fe呈塊狀或粒狀，尺寸較大（ 10 m以下） 。
