波点

Due to the multilayered medium is more close to the real situation, Thomsen's definition of velocity ratio between compressional and shear waves is more accurate.

Thomsen于 1999年提出多层介质条件下的共转换点计算公式，其假设前提与实际情况更为接近，对纵横波速度比的定义也更为精细。

Point wave function as well as from the bandwidths and band gaps.

On the condition of electric-longitudinal-optical phonon strong coupling in both two- and three-dimensional parabolic quantum dots, we obtain the eigenenergies of the ground state and the first excited state, the eigenfunctions of the GS and the first ES by using a variational method of Pekar type.

在电子-体纵光学声子强耦合情况下，我们采用Pekar类型的变分方法获得了二维和三维抛物势限制的量子点中的电子的基态和第一激发态的本征能量和本征波函数。

The dissertation analyzed the characteristic of the development of new high-tech industry at first. It pointed out that having characteristics such as high innovation and high risk, decides that the development of new high-tech industry needs the interference of government. Then, it analyzed the relevant theory of government economic functions and the particularity of the study during the development of new high-tech industry, pointed out the new high-tech industry even needs moderate interferes and supports of government. After that, draw lessons from the analysis train of the "diamond" theory of Michel Porter, it analyzed the demands of the development of new high-tech industry from the angle of catching up, include the regulation function that the key element disposes, demand regulation and preferential policy, strategical planning and organization coordinates, new high-tech enterprise hatches, and the supply of the legal system. Then it carried on international comparative analysis to the government economic functions of some typical countries, to find out the successful experiences with the lessons of the failure.

第一部分分析了高新技术产业发展的特点，指出高投入、高风险及高收益的特点决定了高新技术产业的市场失灵程度较高，且具有一定的公共物品的性质；第二部分分析了一般意义上的政府经济职能的内涵及相关理论，认为高新技术产业更需要政府的适度干预和支持；第三部分借助迈克尔·波特&钻石&理论的分析思路，分析了高新技术产业对政府经济职能的需求，即在要素配置、需求调节、战略规划和组织协调、孵化环节及法律制度方面需要政府的特殊支持；第四部分，对高新技术产业发展中政府经济职能的供给进行了国际比较和评价，探求各国实践中的成功与失败，并对理论分析进行了检验；第五部分对我国发展高新技术产业过程中政府发挥经济职能提出了几点启示。

When a storm estimated of magnitude 9 on the Beaufort scale hit Point Arguello and vessel oscillations of up to 24-foot (7.3 m) peak-to-peak amplitude were recorded.
