Geophysical characteristics of Ordovician carbonate rock were studied using drilling data. Impedance is affected mostly by material properties and reservoirs types, to a negligibly extent by lithology and flow. Compact layers and minor\|fracture reservoirs of Ordovician carbonate rock have characteristics of high density, high velocity and high impedance, and the prediction of minor fractures reservoir is difficult by the general seismic ways. Big fractures and fractured\|vuggy and vuggy and cavity reservoirs of Ordovician carbonate rock have characteristics of minor density and low velocity and low impedance in central Tarim basin, which obviously different from the surrounding rock and produce obvious characteristics in seismic data, so reservoirs can be predicted by applying general seismic data.

根据已钻井资料，对塔中地区上奥陶统良里塔格组岩石地球物理特征进行了研究，结果表明：物性、储层类型对波阻抗影响最大，岩性、流体对波阻抗影响较小；奥陶系碳酸盐岩致密层和小裂缝型储层具有密度大、速度高、波阻抗值大的特点，利用地震常规预测手段较难预测出小裂缝型储层，而塔中地区奥陶系碳酸盐岩大裂缝型、裂缝-孔洞型、孔洞型、洞穴型储层具有密度小、速度低、波阻抗值小的特点，与围岩具有较为明显的差异，在地震上可以产生明显的响应，可利用常规地震资料来预测这种类型储层。

Numerical results indicate that in some cases detonation wave may quench when detonation wave front diffracts at the entrance of expanding chamber due to the extreme declination of temperature and pressure.

结果表明，爆轰波传播至突变截面扩张管道时，由于稀疏波的作用可能会使爆轰波局部熄爆甚至完全熄爆，对于某些敏感度高的反应气体爆轰波可以二次起爆。

Research results show that when the frequency of excitation signal is within 10kHz to 100kHz the wave in free bolt and grouted rockbolt is guided wave which is related to its boundary conditions. Waves with different frequencies have different velocities.

研究结果显示在测试激发波的频率范围内(10~100 kHz)，锚杆中传播的波是一个和边界条件相关的导波，不同频率的波在锚杆中传播的速度不同。

The shoaling wave height is related to wave steepness. Comparing with wave theories the shoaling coefficient of small amplitude wave theory_ which is not related to wave steepness, disagrees with experimental reset. The experimental result has the trend with Stokes third order shoaling theory, but Stokes wave theory overestimates the shoaling coefficient .

波浪之浅化波高与波浪尖锐度有关，微小振幅波理论中浅化波高与波浪尖锐度无关与实测值不符，实验结果在定性上与Stokes波三阶浅化理论有相同之趋势，但在定量上实验之浅化系数较小，理论值有高估的现象。

According to the comparison analysis for the force-displacement relationship obtained from stets of earthquake simulation tests for 3 RC single story structures and the quasi-static test for one RC single story structure (identical with the former 3 models), as well as the analyses for the natural frequency change of the 3 RC single story structures with the increase of the excitation levels, it is found that the accumulated hysteretic energy-dissipation capacity is critical for the structural safety even after serious damage.

本文首先通过对近场破坏性地震动的特性分析，给出了脉冲型地震动的量化定义，并通过研究归一化反应谱变化规律的方法，分析了两类脉冲组合即：波前脉冲组合以及波后脉冲组合对于主脉冲作用效应的影响，总结归纳出波前脉冲与波后脉冲对主脉冲作用效应的不同贡献规律，并通过单层钢结构模型的地震模拟振动台试验验证了理论分析结果，为进一步研究揭示脉冲型地震动中主脉冲的破坏能力奠定了基础。

When the output branch number is more than 2, we can construct a cascade connection of Y-branch waveguides. However, it occupies a large optical circuit area. The power dividers with 2N output branches can be setup by arranging (2N-1) branch waveguide. However, the design of dividing structures with output branches of odd number such as three or five are difficult.

当输出波导数大於2时，可以用串接的方式来增加输出波导数，但是所需空间会变大，而光功率分配器的2N分岔输出是可以由(2N-1)的分岔输出结构改变而来的，所以在设计奇数波导输出像是3或是5的波导数输出结构就成为一个必须的课题。
