Analytical results show that: Anode evaporation rate, which determines mostly the production rate of UFMP, is influenced by the many factors including electric parameters of arc, ambient conditions and material properties et al; Existence and increase of anode ejection can influence the production rate and property of UFMP; It is firstly found and investigated that surface connexity phenomenon of Al anode material. Analyses and calculation show that formation of anode spot and existence of self-magnetic field force play an important part in surface connexity process; Effects of cathode material on prepared UFMP is also experimentally studied and theoretically analysed. It shows that effect of the cathode is inconsiderable under the experimental conditions used in the study. At last, the experimental results found in part one are analysed and discussed in detail.

在茫茫的竹海中，还零星地生长着桫椤、兰花、楠木、蕨树等珍稀植物；栖息着竹鼠、竹蛙、箐鸡、琴蛙、竹叶青等竹海特有的动物；林中除了产竹笋，还有许多名贵的菌类：竹荪、猴头菇、灵芝、山塔菌等，竹海所产的中草药不下200种，堪称一个天然的大药园。

Its mechanism is the use of anthraquinone in alkali conditions off proton surface forming 10 more stable carbon anion face, but because carbon anion and oxygen ion exist between testosterone and enolate type each other changes, cause reaction product complex, at least five, reaction selectivity, product yield, separation difficulties, and product purity is not high, therefore, using the type and quantity of alkali, phase transfer catalyst type, solvent, to optimize the selection process conditions so as to improve the yield target product.

其机理是利用蒽酮在碱存在的条件下脱去氢质子面形成10位较稳定的碳负离子面进行，但是因为碳负离子和氧负离子之间存在酮式和烯醇式的互变，导致反应复杂，产物至少有五种，反应选择性差，产物分离困难，产率低，且产品纯度不高，因此，利用对碱的种类和量的多少，相转移催化剂的种类，反应溶剂的选择，来优化反应工艺条件从而提高目标产物的产率。

However, the 3 groups from medium A exhibited the highest microbial diversity and best decolorization results with 99.53% and 97.42% color removal rate of Reactive Red M-3BE and Acid Red. From them, 16 strains of fungi were isolated and primarily identified as Saprolegniaceae, Eurotiaceae, Erysiphaceae and Physodermataceae . Fungi groups from medium B and D exhibited a bit lower color removal rate of various dyes and only 3 and 2 isolates primarily classified as Saccharomycetaceae and Eurotiaceae were obtained from them. Fungi cultures in medium A and B could produce lignin peroxidase, and those in medium D could be detected higher activity of laccase. All the fungal cultures exhibited very weak activity of manganese dependant peroxidase.

来自A培养基的3组菌群显示出最好的脱色效果和最大的菌群丰富度，对50mg/L的活性红M-3BE和酸性红A溶液的脱色率最高达到99.53%和97.42%，从中分离到了16株真菌，初步鉴定分属于水霉科、曲霉科、节壶菌科和白粉菌科；而B和D培养基中所获得的菌群脱色效果稍差，从中仅得到3株和2株真菌，初步鉴定属于酵母和青霉。A、B两种培养基在各种染料存在下更易产生木质素过氧化物酶，产漆酶能力较弱，而D培养基产漆酶活性较高。
