Study results from both theory and computer simulation were shown in the paper. According to the fact that different characteristics of sound field are displayed with different excited frequency on spherical shell, in the case of different ratio of spherical shell thickness to radius, the pressure directivity of the model can conform to that of the prototype rather well by adjusting the excited frequency of the model. Of course the modification of numerical scale factor is required, in order to make the identity of nondimensional pressure of two systems.
通过理论和计算机仿真研究，结果表明：利用球壳在不同激励频率时声场的不同特性，当球壳厚度半径比不同时，通过对模型激励频率的调节，可以使模型与原型的声场指向性较好的符合，但若使两系统的无量纲声压相符，还需要进行数值比例因子的修正。
On the basis of study on the theory of dynamic compaction, the specific property of soil and the working mechanism of dynamic compaction was studied and also studied was the dynamic compaction method design and the construction technology. Chiefly studied are design principle, computation theory and influence factor etc and studied in detail were the design parameters and construction technology; The on-the-spot test and the quality checking method were introduced; By analyzing the influence factors of reinforced depth and on the basis of dimension comparison, the reinforced depth is calculated by applying the square of the energy on the bottom of the hammer and also, the energy could be decided by the required reinforced depth and the weight of the hammer; On the basis of the diagram of the dynamic compaction method, the method for computing the reinforced range, which is suit for unitary soil layer, is deduced. By combining neural network with the requirement for stopping compaction, the deformation module is calculated, based on which, the capability of the soil after compaction is calculated as the reference for design and construction; With the influence during compaction procedure on the environment studied, the vibration principle is analyzed to work out the safety distance in construction and rational vibration resistance measures.

The undisclosed problems with study 3014 led to a third review, during which FDA managers proposed using foreign postmarketing reports on Ketek as evidence of the product's safety, despite the unreliability of such data.2 Although drug sponsors are required to submit such reports as part of an application, it is extremely unusual to use these data to address critical preapproval safety issues in place of a controlled study.
3014研究中未揭露的问题带来了第三轮审查，FDA管理人员建议使用国外的Ketek售后报告作为产品安全性的证据，尽管这样的数据缺乏可信度。虽然要求药品赞助商提交这样的报告作为申请的一部分，但是却很少用这样的数据来替代对照研究对关键的批准前安全问题进行处理。

Meanwhile, we highlight several research corners for future further study, the trade-offs on resource allocation within perennial plant had not been proved, the relationship of neighbor effects and reproductive allocation was still not so clear for individual plant, there was no definite conclusion on perennial plant reproductive strategy under different neighbor effects and different habitats. The relationship between reproductive allocation and sexual allocation, the cause of resource distribution in anthotaxy structure, the similarities and differences of reproductive allocation and the maintain mechanism within all kinds of reproductivest rategy need a further investigation. In addition, a molecular study is required for explaining the variation mechanism and the biological meanings on seed size research.
