The essential oil was extracted by the water streem distillation . And the components of the essential oil from Sonchus brachyotus were identified by GC-MS. Result: 36 components were identified and represented 89.49% of the peak of the essential oil.

采用水蒸气蒸馏法提取长裂苦苣菜挥发油，然后采用气相色谱-质谱联用仪分析和保留指数分析相结合的方法鉴定其挥发油的化学成分，结果：共鉴定出36种成分，所鉴定的组分占挥发油总离子流色谱峰面积的89.49%。

It is found that,in a first-order differential Raman spectrum,almost all noise peaks are confined within a narrow horizontal band-like region with the base line going through its middle,whereas thesignal peaks shoot up and down much far beyond the region.Based onthis property,a new peak searching method with the aid of first-order differentiation is suggested.In this paper,a R_spectrumpeak labelling program for SPEX 1403 laser spectrometer with DMIBcomputer is reported.The result of peak labelling sho...

作者提出了用一阶导数谱辅助求 Raman 光谱峰值的新方法，较好地解决了谱峰与噪音的识别问题；编制了 SPEX_(1403)激光 Raman 光谱的标峰程序，具有10种不同大小尺寸的绘图功能、9种不同的字号供标峰选用，操作分为自动、半自动和手动三种方式，具有用于图注、实验条件说明的打字，存、取及复制标峰谱图等功能，克服了一般标峰过程中常见的弊病，标峰效果满意。

The features and computation method of classical spectral estimation and modern spectral estimation in deformation series are discussed stressfully.

文中重点讨论了变形序列的谱分析方法一经典谱估计和现代谱估计的特点与计算方法。

And since the actual load table cannot be directly used for computation, an equivalent trapeziform load chart is got from the original load table according to equal-damage principle.

由于实际载荷谱不便于用来进行损伤和寿命计算，所以按照等损伤的原则对载荷谱进行了转换，得到一个等效的梯形载荷谱。

Mono dodecyl phosphate is synthesized using trichloro phosphate and di dodecyl phosphate is synthesized using phosphorous pentoxide. The structures are confirmed by IR and contents are analyzed by GC and HPLC. Mixed esters with different mass ratios of mono and di esters are prepared.

The EL spectrum of the unscored sample can be decompounded into two Gaussian luminescence bands with peaks at about 1.83eV and 2.23eV,while in that of the scored one,the intensity of the 1.83eV peak is enhanced significantly,and a new Gaussian band with peak at about 3.0eV appears.

EL谱形状也有明显不同，表现在：未经刻划样品的EL谱可以分解为两个高斯峰，峰位分别位于1.83eV和2.23eV；而在刻划样品EL谱中1.83eV发光峰大幅度增强，还产生了一个新的能量为3.0eV的发光峰。

Moreover, it added two bands of higher molecular weight and one band which molecular weight is about 25KD, but lost two bands of smaller molecular weight. The bands of peroxidase isozymes showed vitrous plantlets lost three bands such as Rf0.245, Rf0.309, Rf0.382; but added one band of Rf0.200, and the activity of Rf0.136 was increased.

过氧化物酶电泳表明，玻璃苗缺失了Rf值分别为0.245、0.309和0.382的三条谱带，同时增加了Rf值为0.200一条谱带，而Rf值为0.136的谱带活性要明显高于正常苗。

The effects of factors such as complex coupling, interconvert isomer, suffocate spin and chiral carbon on the appearance of the spectra were studied and discussed in the paper.

采用600MHzNMR谱仪较详细地研究了不同类型有机磷农药的NMR谱图，分析了复杂偶合、直变异构、受阻旋转、手性碳原子等因素对有机磷农药的NMR谱图影响。

Results A seven-line spectrum characteristic of 5, 5-dimethyl-2-pyrrolidone-N-oxyl was formed at first, at 60min the spin adducted DMPO-OH with four-line spectrum characteristic and at 120min, no spectrum was observed.

结果 酸性氧化电位水放置0和30min时EPR谱图信号是7条特征谱线组成的DMPOX的信号，60min后出现由4条谱线组成的DMPO-OH的EPR信号，120min则基本检测不到EPR信号。
