D'Alembert Solution in one dimension wave equation is a very important basic formula.

弦振动方程中的D'Alembert公式是偏微分方程中一个非常重要的基本公式。

This thesis has mainly discussed D'Alembert Solution in one dimension wave equation by using arithmetic operators algorithm.

主要讨论了运用算子的方法推导出弦振动方程中的D'Alembert公式。

In this thesis, we express one dimension wave equation by arithmetic theory and prove D'Alembert Solution in the light of method on one stage linear partial differential equations.

本文从另一角度即算子的方法，将弦振动方程写成算子的形式，再根据一阶线性偏微分方程的求解方法，最终推导出D'Alembert公式。

However, it is that absence of proof that is perhaps most damning.

缺乏实验证明也许是弦理论最致命之处。

He delves into the heart of Latin America for the folksy "Carioca Cat"(named after the cool "screech" at the end of some of the lower-toned 12-string lines) and playful flamenco-tinged Danza del Corazon.

他为研究民间的"Carioca Cat"（以在一些低声调12弦线的末端发出刺耳的尖音而命名）和轻快的西班牙弗拉门科吉他的叮铃声"Danza del Corazon"走遍拉丁美洲。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
