二十九碳烷

In addition nC〓, nC〓, two isomers of C〓 sterene and three isomers of C〓 isoprenoid hydrocarbons were also identified from aliphatic fraction of pyrolyzed product at 200℃. After pyrolyzed at 300℃, the main aliphatic hydrocarbons were normal alkanes ranged from C〓 to C〓, with C〓 as the main peak and C〓 as the second main peak. Meanwhile, pristane, phytane and C〓 sterane were also detected. In the pyrolysates at 400℃ and 500℃, the content of saturated hydrocarbons decreased, the range of normal alkanes distribution became narrow and the main peak was nC〓. Low concentration of C〓-C〓 steranes was detected and the content of C〓-C〓 increased more.

在200℃热模拟产物饱和烃馏分中除检测出两种长链烯烃外，还检测到正十九碳单烯烃、正三十五碳双烯烃、两个碳二十八甾烯的同分异构体和三个C〓类异戊二烯烷烃化合物同分异构体。300℃模拟产物饱和烃主要为正烷烃，正烷烃的碳数分布范围为C〓-C〓，以C〓为主峰、C〓为次主峰；另外，样品中还检出姥鲛烷、植烷和C〓甾烷等化合物。400和500℃热模拟产物中的饱和烃含量下降，正烷烃系列碳数分布范围变窄，主峰碳后移至C〓，检测到低浓度的C〓-C〓甾烷系列化合物，另外，C〓-C〓藿烷系列化合物含量进一步增加。

The results showed that the unsaturated fatty acid content of pecan kernel oil was 89 0%,and 13 kinds of unknown components such as nonadecaol,8 hexyl pentadecane,10 methyl eicosane,11,14 eicosadienoic acid,1 bromo 8 heptadecyne,9 hexyl heptadecane,tetracosane,13 docosenoic acid,1 bromo 7 nonadecyne,15 tetracosenoic acid,hexacosanoic acid,7 hexyl ei...

研究结果表明：山核桃仁油中的不饱和脂肪酸 w =89 0 %，未知成分是十九醇、8 己基十五烷、10 甲基二十烷、11，14 二十碳二烯酸、1溴 8 十七炔、9 己基十七烷、二十四烷、13 二十二碳烯酸、1 溴代 7 十九炔、15 二十四碳烯酸、二十六酸、7 己基二十烷、二十七烷共 13种，其中13 二十二碳烯酸、15 二十四碳烯酸、十九醇等具有较强的生理活性和药用价值

SM6 and SM7 of uncrystal were analyzed through GC-MS, the results showedthat SM6 main contained unsaturated fatty aldehyde with fragrance, i.e.-2,4-decadienal(58%), tetradecanoic acid (55.78%), 2-decenal(50%), Phthalic acid isobutylundecyl ester(47%), 2, 4-Decadienal(41%), 2-Undecenal (31%), 2-Methyl-Z,Z-3, 13-octadecadi-enol(18.84%), and SM7 contained saturation alkanes, i.e. 1, 2-Benzenedicarboxylic acid, butyl cyclohexyl ester(23.90%), Triacontane(22.63%),Nonacosane(21.04%), Heptadecane(18.84%), Octacosane(13.58%). Toxicological experiments were done to insure the pigment safety.

并对紫红丝膜菌色素非晶体部分的黄色油状物SM6和紫色粉末物SM7作了GC-MS分析，结果显示SM6中主要为具有香气成分的不饱和脂肪醛，其中含量较高的依次为：-2，4-癸二烯醛(58％)、十四烷酸(55.78％)、2-癸烯醛(50％)、邻苯二甲酸异丁基十一烷酯(47％)、2，4-癸二烯(41％)、2-十一碳烯醛(31％)、2-甲基-Z，Z-3，13-十八碳二烯酸(18.45％)等；SM7中主要为饱和直链烷烃，其中含量较高的依次为：1，2-苯二羧酸丁基环己酯(23.90％)、三十烷(22.63％)、二十九烷(21.04％)、十七烷(18.84％)、二十八烷(13.58％)。

Results11 separated constituents were identified, the contents of 3 compounds were over 20%. The main constituents in extracts were Bis(2-ethylhexyl) phthalate (21.51%), Nonacosane (25.73%), Stigmastan-3,5-dien (25.73%).

结果从海南裂叶山龙眼叶超临界二氧化碳20 MPa压力提取物中共分离出11个组分，全部进行了鉴定，其中含量高于20%的有3个，为邻苯二甲酸二(2-乙基己基)酯（21.51%）；二十九碳烷（25.73%）；3，5-二烯豆甾烷（25.73%）。

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。
