In the meantime, the peak value of structure resonance contributes little to the response. The distribution of vertical displacement and wave bending moment of transverse section, which is along the direction of the floating structure length, appears unsymmetrical character. According to the wave scatter diagram of BI sea area of northwest pacific, which is in fairly calm condition, the amplitude values of long term prediction of wave bending moment in midsection and deck bending stress are quite large.

根据西北太平洋B1海区波浪散布图计算的波浪弯矩和舯剖面甲板弯曲应力的长期预报值是相当高的，日本的箱式浮动机场的概念设计中，浮体结构设置在离岸很近的平静水域且外围设置了防波堤，这可能是出于改善超大型浮体结构的运动性能和为了满足结构强度要求。

The governing equation is the mild-slope equation. Finite element method has advantage to treat complicated boundary. The second order radiation boundary condition is expanded to improve the wave model for large incident wave angles. The validity of the second order radiation condition is examined through varying arbitrary wave incident angles.

模式将以包含波浪绕射及反射之缓坡方程式建立数值模式，利用有限元素法易於处理不规则边界的优点，引用二阶近似辐射边界条件，扩展波场模式处理大角度波浪入射的能力，探讨在未碎波的情形下，二阶辐射边界条件对於任意角度波浪入射之适用情形。

Functional T wave change accounted for 99.24%(519/523).Among which, 144 cases of T wave change were self-restoring when physiological inducements were removed.14 with T wave normal variant and 195 with negative treadmill exercise tests, and 166 with positive propranolol tests.

T波改变判为功能性占99.24%(519/523)，其中去除生理诱因T波自行恢复144例，T波正常变异14例，平板运动试验阴性195例，普萘洛尔试验阳性166例。

With the shadowgraph method, three ultrasonic pulses in water, which corresponds to the conversion modesof the fast compressional wave the transverse wave and the slow compressional wave in the sample of fluid-saturatedporous medium respectively, were observed and recorded by CCD camera.

用阴影法和CCD照相，观测到声脉冲透过流体饱和孔隙介质（按英文"Fluidsaturatedporousmedum"的第一个字母缩写为FSPM）样品后在水中传播的三个声脉冲，这三个声脉冲分别对应于FSPM样品中的三种体波的转换模式。

This paper analyzes the action of air shock wave and compressive wave in oil to the basement structure, and confirms the shock wave shape and each parameter.

考虑到这种情况以及世界范围内的人防工程建设的平战结合趋势，我国制定了"长期坚持、平战结合、全面规划、突出重点"的人防工程建设方针。

It is our function generator in learning, scientific research and other aspects indispensable tool. Today we have to design a square wave, sine wave and triangular wave function for release.

因此函数发生器是我们在学习，科学研究等方面不可缺少的工具，今天我们要设计一种能产生方波、正弦波、三角波的函数放生器。

The other function is to wave, sine wave and triangular wave statistical analysis.

功能是对方波，正弦波和三角波进行统计分析。

It can measure the sine wave, square wave, triangle wave frequency.

它可以测量正弦波、方波、三角波的频率。

Power should be sinusoidal wave form, the fundamental wave does not exceed 5% of harmonic wave.

电源的波形应为正弦波，谐波分量不超过基波的5%。

Results show that amplitude of displacement excited by vertical incidence wave is larger than that excited by inclined incidence wave and not influenced greatly by the incidence angle. In vertical incidence, amplitudes of displacement of two points at the same altitude along each cavern are basically identical and maximum relative displacement occurs between top and bottom point of the cavern. While in the case of inclined incidence, displacement amplitude on sides meeting the wave is larger than that on leed sides, and maximum relative displacement occurs on left skewback and bottom of the cavern.

结果表明，位移幅值受入射角度的影响不敏感，竖直入射比斜入射情况要大；竖直入射时，各洞室两侧同一高程处的位移幅值基本相同，相对位移差最大部位为洞顶与洞底，而斜入射时迎波面比背波面一侧位移大，且相对位移差最大部位为洞室迎波面的左拱座与洞底。
