Part II:The electrocatalytic oxidation of guanine, adenine, guanosine-5'-monophosphate and ssDNA was performed in the presence of iron bis(2,2':6',2"-terpyridine) and Fe tris(1,10-phenanthroline) complexes as a homogeneous catalysts with Fe redox couple. The electrocatalytic and electroanalytic properties of guanine with an iron bis(2,2':6',2"-terpyridine) complex was measured by the amperometry method using the rotating disk electrodes. Electropolymerization of iron tris(5-amino-1,10-phenanthroline) complex produced thin polymer films on a gold, platinum, nickel, and glassy carbon electrode.

第二部分利用iron bis(2，2'：6'，2&-terpyridine)和Fetris(1，10-phenanthroline)之金属错合物当作均相的催化剂对於鸟嘌呤、腺嘌呤、5'-鸟嘌呤核苷单磷酸盐(guanosine-5'-monophosphate)和单股DNA进行电催化氧化的研究。iron bis(2，2'：6'，2&-terpyridine)之金属错合物对於鸟嘌呤的电催化和电分析性质可利用计时安培法并使用旋转环-碟电极进行测量。rontris(5-amino-1，10-phenanthroline)之金属错合物可经由电聚合过程所形成的聚合薄膜固定在黄金、白金、镍和玻璃碳电极上。

They were two new compounds, [cyclo(Pro-Val-Phe-Phe-Pro-Val-Phe-Ser-Leu),7],[2-N-(1-methoxycarbonylethyl)guanosine, 10], and eight known compounds,(p-hydroxybenzoic acid, 1),(methyl succinate, 2),(russulaceramide, 3),(phenylalanine, 4),(guanine, 5),(β-carboline, 6),(uridine, 8), and (adenosine, 9). All the compounds were isolated from Amanita exitialis for the first time.

分别为：对羟基苯甲酸(p-hydroxybenzoic acid，1)、丁二酸二甲酯(methyl succinate，2)、神经酰胺(russulaceramide，3)、苯丙氨酸（phenylalanine，4）、鸟嘌呤核苷(guanine，5)、β-咔啉(β-carboline，6)、环（脯氨酸-缬氨酸-苯丙氨酸-苯丙氨酸-脯氨酸-缬氨酸-苯丙氨酸-丝氨酸-亮氨酸） [cyclo(Pro-Val-Phe-Phe-Pro-Val-Phe-Ser-Leu)，7]、尿嘧啶核苷(uridine，8)、腺嘌呤核苷(adenosine，9)、2-N-(1-甲氧羰基乙基)鸟苷[2-N-(1-Methoxycarbonylethyl)guanosine， 10]。10个化合物均为首次从致命鹅膏中分离得到，其中化合物7和10为新化合物。

The cordyceps grass vegetable, the cordyceps grass is sour, the cordyceps grass many sugar, SOD—enzyme, guanin, urine, the gland... etc., a materials of the pit are all with the natural cordyceps grass homology, the poison reason evaluation:Have no poisonous side effect to the human body, is a stub in the world new species of biggest cordyceps grass in very unique body.

虫草素、虫草酸、虫草多糖、SoD、腺嘌岭、鸟嘌呤、尿嘧啶、腺苷等，核苷类物质都与天然虫草相同，毒理评价：对人体无任何毒副作用，是一株世界上绝无仅有形体最大的虫草新品种。

Any of various compounds consisting of a sugar, usually ribose or deoxyribose, and a purine or pyrimidine base, especially a compound obtained by hydrolysis of a nucleic acid, such as ''.

核苷由糖，通常是核糖或脱氧核糖和嘌呤或嘧啶基组成的化合物，尤指从核酸水解中获得的化合物，如腺嘌呤核苷或鸟嘌呤

Any of various compounds consisting of a sugar, usually ribose or deoxyribose, and a purine or pyrimidine base, especially a compound obtained by hydrolysis of a nucleic acid, such as adenosine or guanine.

核苷由糖，通常是核糖或脱氧核糖和嘌呤或嘧啶基组成的化合物，尤指从核酸水解中获得的化合物，如腺嘌呤核苷或鸟嘌呤

Nucleosides are compounds composed of a purine or pyrimidine base (usually adenine, cytosine, guanine, thymine, uracil) linked to either a ribose or a deoxyribose sugar.

核苷是由嘌呤基，嘧啶基(通常是腺嘌呤，胞嘧啶，鸟嘌呤，胸腺嘧啶，尿嘧啶)与核糖或脱氧核糖相连而组成的化合物。

In DNA the corresponding sugar is the closely related deoxyribose. A ribose molecule combined with adenine, guanine, cytosine, or uracil forms a nucleoside; adding a phosphate group forms a nucleotide.

去氧核糖核酸中相应的糖类和去氧核糖密切相关核糖分子和腺嘌呤、鸟嘌呤、胞嘧啶或尿嘧啶形成核；再加上磷酸盐和磷酸酯便成为核。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
