The effects of excess air coefficient and cylinder pressure on these spectra are also studied. The experimental resultS show that the three different combustion phases in a gasoline engine have different combustion characteristic spectra: a large number of atoms, molecules, ions and radicals which are in their excited states are existing during the ignition process, with the development of the combustion, the spectra intensities of CH, C2 radicals increase rapidly.

实验结果表明，汽油机三个不同的燃烧阶段具有不同的燃烧光谱特征：着火过程中，存在着大量的处于激发态的分子、原子、离子、自由基等活化中心的束缚态光谱，随着燃烧发展，CH、C2自由基的光谱强度明显加强；当减小过量空气系数时，光谱强度变弱并且着火延迟期增长；自由基特征光谱的光强变化曲线可以反映它们在燃烧过程中的浓度变化。

It is shown that the mechanical properties including Young's modulus, tensile strength, critical strain and stress under buckling can be enhanced with the decreasing of intershell spacing. The shear strength can be enhanced by 2-3 orders of magnitude when the intershell spacing is reduced to 20%, which is also dependent on commensuration. Zigzag-type carbon nanotubes have higher shear strength. The axial stress in tubes when the load transferring from outmost tube to inner tube is observed as well.

研究了单壁纳米管束横截面的六方化失稳现象，给出各种管径的面内压力－应变关系曲线；每条曲线都给出一个明显的拐点而且有很强的非线性；线弹性模量与参考构形有关，也受管直径的影响；分析了管束横截面的晶格不稳定性特征，表明晶格的缺陷能够明显的减小临界值；模拟了在不同应变下纳米管束对静水压的反应，发现不同压力下的截面形态不同，在很高压力下相邻管之间会形成化学键。

The basic idea is that we use entropy and conditional entropy to measure whether a feature type grasps some of the information for syntactic structure prediction.

如果加入某个特征类型之后当前句法结构的不确定性明显下降，则认为该特征类型抓住了上下文中影响句法结构的某些主要信息。

Based on the radar dense data of convectional cloud on June 12,2004 in Yongdeng county,choosing two similar convectional clouds as seeding and non-seeding cloud,the remarkable changes of radar echo parameters of the seeding cloud compared with the non-seeding cloud were discussed in this paper,and the rain enhancement effect was evaluated primarily with ground observational rainfall data.The results show that many aspects of the seeding cloud,such as precipitation,life characteristic and vertical characteri...

利用2004年6月12日甘肃省永登县雷达观测对流云的加密资料，选取了2次相似对流云过程分别作为目标云和对比云，探讨了目标云作业前后较对比云雷达回波有关参数的显著变化，并结合地面雨量点观测资料对地面人工增雨作业效果进行了初步分析，结果表明：目标云在降水、生命期特征、回波垂直特征参数变化方面，表现出作业前后较对比云存在明显差异，目标云作业40 m in后地面产生0.6 mm降水，而对比云则从新生发展到减弱消散阶段经历较短的时间(30 m in)，地面并无降水产生，从而推断本次人工增雨达到了一定的预计效果。

精神分裂症患者凶杀案件的犯罪学特征明显不同与正常人，其责任能力的评定与其精神病理学特征及严重程度有关。

The crystallographic textures in the first group are characterized by the relatively weak {111} and {114} components;for the second group, the characteristic texture co...

结果表明，带铸材试样中存在{111}与{114}特征织构，织构强度均较弱；铸坯切片中存在{111}与{001}特征织构，并且因局部凝固冷速不同存在明显的织构强度差异。

Volcanic gas reservoirs of low permeability in the carboniferous of a basin are characterized by deep burial depth, complex genesis, many types, wide distribution and non-evident expressions in three-porosity log curves, as well as the variedvalues of density and compression wave of main four volcanic gas reservoirs (such as the basalt, andesite, dacite and rhyolite). So a number of effective methods based on three porosity log data cannot work in identifying the volcanic gas reservoirs of the carboniferous of the basin.

石炭系火山岩的低渗透气藏具有的埋藏深、成因复杂、类型多、分布广、三孔隙度曲线响应特征不明显等特点，并且主要的四种火山岩气藏：玄武岩、安山岩、英安岩、流纹岩的密度和纵波时差测井值差别较大，因此使基于三孔隙度测井资料的一系列识别气层的有效方法在该盆地石炭系火山岩气层的识别中无明显效果。

The intermediate-basic volcanic rocks with SiO2 content less than 57.48 wt% are high in Al2O3(20.22-16.34 wt%) and K2O, enriched in large ion lithophile elements, show obvious Nb, Ta negative anomaly, these are same to the basalts which formed in island arc. The andesite, dacite and rhyolite rocks with SiO2 content between 62.11-75.19 wt%, are similar with the I-type granitic rocks formed in island arc in their geochemistry. It is suggested that the Jueluotage area of East Tianshan was in island arc setting during Late Carboniferous, when the subduction of the ancient Asian Ocean was in progress.

其中w(SiO2)小于57.48%的中基性火山岩具有高w(Al2O3)(16.34%~20.22%)，较富钾，富集大离子亲石元素，具明显的Nb、Ta负异常；w(SiO2)介于62.11%~75.19%之间的安山岩、英安岩和流纹岩岩石化学特征与准铝质的Ⅰ型花岗质岩石相似，其地球化学特征也反映出岛弧花岗岩的特点，表明东天山觉罗塔格地区路白山一带在晚石炭世仍处于古亚洲洋向南俯冲的岛弧环境。
