层层

In every plate, there are areas where the layers of rock are crumbly, not solid, and when this crumbles, anything could happen on the surface, from a drop to a rise, including shifts in the water table.

在每一个板块，还有一些领域的层层岩石破碎，不稳固，而当这山河，什么事情都可能发生，从表面上看，从下降到上升，包括轮班的地下水位。

The results showed that the ultrasonic extraction is a rather ideal method of extracting red P. tha fortuneana pigment. Cyanidin3glucoside can be hydrolysised to aglycon cyanidin under the conditions of 90℃, 9％HCl and 11min.Silica gel thinlayer chromatography with developping agent benzene∶ethyl acetate∶formic acid = 2∶2∶1 is better to separate cyanidin. Cyanidin is stable to heat and light, unstable to Zn2+ and Fe3+ and Cu2+, insensitive to Co2+ and Bi3+, befitting to acidic condition.

Father in the telephone says to the small jade, so many years he all always for the mistake that the oneself commits at the beginning and then the regrets is sad, always think Be ownly livinging of the year has an opportunity and can make up past of those fault, own can of daughter but has been can't forgive him, his crime feeling on aggravating in multiple layers, the conscience has been can not be quiet and peaceful, hoping the small jade can give him an opportunity, be is give him a Be a father to wish to see to see a daughterly end to hope at first.so know now she a person will not let the other people help to answer the phone at home, want to ask her viewpoint in person, worry otherwise can not sleep ＂.hear this small jade know how answer, let go of a telephone silently.

电话里父亲对小玉说，这么多年他都一直为自己当初犯下的错误而后悔难过，总想在自己的有生之年有机会能弥补过去的那些过错，可自己的女儿却一直不能原谅他，他的罪恶感就一层层的加重，良心一直不得安宁，希望小玉能给他一个机会，就当是给他一个作为父亲想见见女儿的最后原望。所以现在知道她一个人在家，不会让别人帮接电话，要亲自问问她的想法，不然担心得睡不着＂。听到这小玉不知怎么回答，悄悄地放下电话。

The antimicrobial test and researched was done on wide distillation of different solvents on Terpenoid, polarity separation of ethanol distillable substance, thin layer chromatography of different polarities and distillation of amylase. The results showed that the active substance distilled by 95% ethanol and V methanol: toluene=3:1 had stronger antimicrobial activity on Agaricus blazei Murrill. The antimicrobial activity of ethyl acetate was stronger than wide distilling substance with ethanol, but the water part has not antimicrobial effect. Two straps of ethyl acetate phase（Rf0.57、Rf0.63）(0.1g/ml)had stronger antimicrobial activity on Agaricus blazei Murrill, the antimicrobial zone on Pseudomonas was 19.3mm. The bacteriostatic activity of chromatography strap of water phase was rather weaker, the water solution (0.5g/g) of amylase had better effect on pathogenic fungus of Agaricus blazei Murrill, its antimicrobial zone on Aspergillus niger, Citrinin, Trichoderma viride were 10.8 mm, 7.9 mm, 5.3 mm.

通过对日本凹顶藻以不同溶剂的粗提、乙醇提取物的极性分离、不同极性的薄层层析和多糖的提取，进行抗菌试验的研究，发现95%乙醇和V甲醇：甲苯为3∶1的提取的活性物质具有较强的抗姬松茸的病原细菌活性，乙酸乙酯相对病原细菌的抑菌强于乙醇的粗提物，而水相基本无抑菌效果，乙酸乙酯相的两个带（Rf0.57、Rf0.63）浓度为0.1g/ml具有较强抗姬松茸病原细菌的活性，对假单孢杆菌抑菌圈达到19.3mm，水相层析带的抑菌活性较弱，多糖的粗提物配成0.25g/g的水溶液对姬松茸病原真菌有较好的抑菌效果对黑曲霉、桔青霉和绿色木霉的抑菌圈分别达到10.8 mm、7.9 mm、5.3 mm。

The antifungal activities of these materials were investigated and build foundation to develop low poison plant antifungal products. In experiment, polyphenols were extracted by reflux ectraction method which applyed petroleum ether to degrease and methyl alcohol solvent. Phenolic hydroxyl were examined and inspected by colour-developing reaction and the content of total polyphenols was determined by UV-spectrophotometry. Screening test were performed to the antifungal activities of polyphenol extraction by the tube dilution method to the selected ten pathogenic fungus such as Dothiorella gregaria, Rhizoctonia solani, Phyllosticta pirina, and the minimal inhibitory concentration were measured. The column chromatography and thin layer chromatography were applyed to separate and analyse cortex extracts of Dracaena cochinchinensi Lour.
