物理医学的

With the modernization of scientific and technological progress and industrial development, physics, chemistry, biology, engineering, aerospace, medical, economic and financial areas of the many principles and laws can be described as an appropriate ordinary differential equations, such as Newton's laws of motion, gravity law, law of conservation of mechanical energy, energy conservation law, the law of population development, ecological population competition, disease transmission, genetic variation, the trend of the stock's up V, the floating interest rates, the market equilibrium price changes.

随着科技进步和工业现代化的发展，物理、化学、生物、工程、航空航天、医学、经济和金融领域中的许多原理和规律都可以描述成适当的常微分方程，如牛顿的运动定律、万有引力定律、机械能守恒定律，能量守恒定律、人口发展规律、生态种群竞争、疾病传染、遗传基因变异、股票的涨伏趋势、利率的浮动、市场均衡价格的变化等。

It has been developed to be a cross-subject of numerical and applied mathematics and system science.

声波散射反问题是一类典型的数学物理反问题，在无损检测、医学成像、遥感、雷达、声呐、石油、地矿和海洋探测等领域都有着广泛而重要的应用空间，迄今已发展成为融合计算数学、应用数学和系统科学的具有交叉性的热门学科方向，对其计算方法的研究正吸引着国内外众多学者的浓厚兴趣。

Then the more advantaged detection technique is needed to be used in the pile detection. Computed Tomography is just such an advantaged technique, which has been widely and maturely used in iatrology, and in exploration of geophysics and scatheless detection in recent twenty years. It can reflect the inside structure of the inspected object precisely and gain the clear figure.

这就要求把更先进的检测方法应用到桩基检测中来，而层析成像技术就是一种非常先进的检测方法，它在医学中应用的非常成熟和广泛，最近二十年才应用到地球物理探测和无损检测中来的，它能精确反演被测物体的内部构造，得到清晰的图像。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
