The blast power of TBE was higher due to the enhancement of afterburning to shock wave. The percentage of total energy released in explosive reaction of TBE was about 42% as analysis, which indicated that it had potential to be improved. A modified thermobaric explosive containing chemically active material was studied by experiment.

对含化学活性材料温压药剂M-TBE的实验表明：其冲击波曲线有两个规律的正压作用区；二次冲击波在火球区外形成，火球区内是后续燃烧反应对爆炸波增强而引起的压缩波积累压力平台；二次冲击波峰值压力不小于第一个冲击波的40%，二次冲量占总冲量的12.5%~43.7%，其对爆炸/冲击波威力的贡献不可忽略；化学活性材料对温压药剂的后续燃烧反应有增强作用，有利于二次冲击波的形成和传播。

By analysis of frequency spectrum based on MATLAB platform, wavelet method in the application of cutting out a section of inputting earthquake wave was presented. In the process of pseudo dynamic test results, the method of non-dimensional representation and analytic representation of hysteretic curve was provided. The above two methods will help to compare dissipation energy capacity of this structure at the different acceleration peak value stage of pseudo dynamic test more precisely and comparably.

通过基于MATLAB的地震波频谱分析，说明了小波分析方法在拟动力试验中地震波截取方面的应用：在拟动力分段试验数据的处理方面，本文将试验结果的无纲量表示方法以及曲线的多项式拟合法引入滞回曲线的数据处理，这将有助于拟动力试验不同加速度峰值条件下，各阶段结构耗能能力的客观比较。

Results show that:(1) For each particle size of andalusite, variation tendency of the properties of the material is generally the same: the maximum of bulk density, compressive strength and rupture strength appears in the range of 5%-10% content of fiber, these properties of the material remarkably decrease as the fiber content exceed 10%; while at the same fiber content, the properties of the material increase with the increase of firing temperature.

结果表明：(1)对于不同粒度的原料，性能变化规律大致相同：在同一烧成温度下，体积密度、常温耐压强度、常温抗折强度在5％～10％之间出现峰值，加入量超过10％之后材料的性能明显下降；在相同的纤维含量下，随着烧成温度的提高，试样的各项性能均有所上升。

At 920 8C, the sample exhibits a high amount of crystalline phase but, at 1050 8C, it is possible to notice a small decrease of the anorthite peak intensity, benefiting the growth of diopside.

The accumulation of glutenin subunits is in parabola and its peak is at 20-25 days after anthesis

谷蛋白亚基积累过程呈抛物线型，峰值出现在开花后20-25天。

The receptance characteristics of track system has been predicted with the three dimensional track for high frequency vibration, with this model, the structure parameters of track system affect onreceptance have been discussed. The results show that the stiffness of ballast, sleeper mass, and stiffness of railpad are the main factors affecting on resonance and antiresonance under second resonance frequency.

利用轨道系统高频振动模型预测了各种参数对轨道系统导纳特性的影响，结果表明：道床刚度、轨枕质量和轨枕垫刚度是影响轨道系统第二阶共振频率以下共振和反共振的主要因素，随道床刚度增加，或轨枕质量减小，或轨枕垫刚度增加，第一、二阶共振和第一阶反共振频率增加，道床阻尼、轨枕垫阻尼主要影响第一、二阶共振和第一阶反共振振幅，阻尼越大，共振峰值和反共振谷值越平缓。

Six cases were found to have normal direction of flow,but in the functional test of the involved upper limb,the reversal flow peak value of the ill vertebral artery increased,or the direction of flow turned from normal to reverse.2-dimensional ultrasound showed that 90% of subclavian steal syndrome were caused by arteriosclerosis,10% caused by aortitis.
