对位红

In general, the following technical achievements could be concluded: 1. A sensitive and selective liquid chromatography-tandem mass spectrometric method has been developed to determine trace para red、Sudan I～IV、Sudan red B、Sudan red G、Sudan red 7B、Sudan Black B、Methyl Yellow、Toluidine Red、Fast Garnet GBC Base、Auramine、Oil Orange SS and Sudan Orange G in food, respectively.

详细分析研究了食品中微量的对位红、苏丹红Ⅰ-Ⅳ、Sudan red B、Sudan red G、Sudan red 7B、Sudan Black B、Methyl Yellow、Toluidine Red和Fast Garnet GBC Base7种苏丹红类染料、Auramine和Oil Orange SS染料、以及Sudan Orange G染料的快速、灵敏的液质测定方法。

The calculated results showed that the decrease of the pyridylene content and the para-linked pyridylene in the backbone of the polythiophene resulted in a narrowed energy gap and bathochromic absorption and emission peaks.

另外，共聚物主链中吡啶成分减少以及吡啶的对位连接导致了能隙的变窄和吸收及荧光波长的红移。

The bay area has no substituent and has electron-withdrawing groups,such as bromine atom,cyano-group and 4-formyl phenoxy group compounds have strong absorption in 525 nm,when excitated them,they have strong yellow and salmon pink luminescence bettwen 538 and 566 nm.When introduce electron-donating substituents,such as phenoxy group,morpholinyl,piperidinyl and n-butylamino group,the absorption bathochromic shift while the electron-donating ability is improved,bettwen 536 and 692 nm have strong absorption,reach to the near-infrared region. When excitated them,only the phenoxy group compound has strong salmon pink luminescence in 572 nm,the others have no fluorescence.

其中，港湾位无取代的以及含吸电基团(—Br、—CN、对甲酰基苯氧基)化合物在525 nm左右处均有很强的吸收ε＞10~4M~(-1cm~(-1)，当光激发时，港湾位无取代、溴代和氰基取代物发出538～547 nm的强烈黄色荧光，对甲酰基苯氧基取代物则发出566 nm的强烈橙红色荧光；含供电基团(苯氧基、吗啉基、哌啶基、正丁氨基)化合物随着供电子能力的增强，吸收发生红移，在536～692 nm处均有很强的吸收ε＞10~4M~(-1cm~(-1)，达到了近红外区，当光激发时，只有苯氧基取代物发出572 nm的强烈橙红色荧光，而含氮供电基取代物均发生了荧光淬灭。

The results showed that: with the regression analysis of Betula platyphylla, Pinus koraiensis, Abies nephrolepis, Picea koyamai var koraiensis, and Betula costata, there was a significant negative correlation between neighborhood interference index and the growth (0.40~0.89) and the correlation extent depended on the neighborhood influence zone and slope. The neighborhood influence zone corresponding to maximal regression coefficient R~2 was the neighborhood influence radius. Based on the linear subsection regression between neighborhood interference index and influence zone of five species, the neighborhood interference index increased with the increasing zone and there was a previous increasing trend in a certain scope, while the increasing trend slackened beyond the zone. The neighborhood influence zone corresponding to transition point was the neighborhood influence radius. The neighborhood interference index positively correlated with the neighborhood influence zone and the range of R~2 was 0.40-0.64. With the analysis of tree cores of Juglans mandshurica, Fraxinus mandshurica at middle and lower slope in a plot which was fostered in 1995, the distance which the growth release farthest neighborhood and object stub was judged, thus the neighborhood interference radius was inferred. According to the studies, we found that the neighborhood interference radius was different among different trees, even if the neighborhood interference radius of the identical tree species also had the difference at different slopes.

结果表明：通过对白桦、红松、冷杉、红皮云杉和枫桦树种进行邻体干扰指数与生长量回归分析发现，邻体干扰指数与生长量呈显著负相关(0.40～0.89)，相关程度因邻体影响范围和坡位而异，R~2达到最大值所对应的影响范围即为邻体影响半径；通过对白桦、红松、冷杉、红皮云杉和枫桦树种进行邻体干扰指数与影响范围的线性分段拟合，邻体干扰指数随影响范围的增加而增加，其在一定的范围内上升较快，而超出该范围后上升的幅度变慢，变化的转折点所对应的影n向范围可以判定为邻体影响半径，线性回归显著(0.40～0.64)；通过对1995a抚育的胡桃楸、水曲柳样树进行研究，分析邻体树种的中坡位和下坡位的生长锥芯，判断产生生长释放的最远邻木与基株树桩所对应的距离，推断邻体影响半径；根据研究发现，邻体影响半径因树种不同有一定的差异，即使同一树种的邻体影响半径在不同坡位也有一定的差异。
