The results show that in the later stage of the nucleation process, ① The maximum slip velocity is monotonically accelerating; ② The slipping hot spot migrates spontaneously from a certain instant, and such migration is spatially continuous; ③ When the maximum velocity reaches a detectable order of magnitude (at least one order of magnitude greater than the loading rate), the remaining time is 20 hours or more, and the temporal variation of slip velocity beyond this point may be used as a precursory indicator; ④ The average slip velocity is related to the remaining time by a log-log linear relation, which means that a similar relation between rate of microseismicity and remaining time may also exist; ⑤ When normal stress variation is taken into account, time scale of such processes can be extended by about 2 times.
结果表明，在成核的后期阶段：①最大位移速率单调加速增加；②滑动热点在后期阶段开始自发性迁移，且在空间上连续；③当最大滑动速率达到可以明显探测的量级时（高於载入速率一个数量级以上），倒计时间为20小时或更长一些，这时的速率变化可作为临震预测标志；④平均滑动速率与倒计时间的关系在临震阶段呈对数线性趋势，由此可推测微震活动增长率与倒计时间同样存在对数线性关系；⑤正应力的变化对上述时间尺度有延长作用，使之大致增加到原数值的2倍。

Further, the Fourier transform method is replaced by the Hartley transform method in many cases. Theses schemes are to utilize current computer facilities to provide seismic data efficiently for testing purposes. However, to provide 3-D data for testing some seismic processing methods such as the 3-D residual migration velocity analysis is still time consuming. To overcome the obstacle, we present modeling with synthesized areal sources and linear sources. The data from modeling of the synthesized areal sources can be used to test some methods that deal with the synthesized area record without the synthesis, while the data from modeling of the linear source can be used to test some schemes in which the controlled illumination is necessary.
本文对利用傅里叶变换的地震波数值模拟进行了改进和推广，并提出用哈特莱变换取代傅里叶变换的方法，以便利用当前的计算机资源有效快速地模拟地震波传播；尽管如此，用数值模拟方法提供三维合成数据以验证一些地震处理方法(如本文中的三维剩余偏移速度分析方法)仍因计算量庞大、计算时间长而有困难，为此，我们提出了合成震源正演模拟和线形震源正演模拟，合成震源正演模拟可以有效地提供合成震源记录以验证一些涉及合成震源记录相关的地震处理方法，而且不需要耗时较长的合成过程，利用线形震源正演模拟可以将合成数据用于需要利用控制照明的地震处理方法中。
Result The total migration amount of the 2 kinds of plants in aerial parts on Pb was increased with the increase of lead ion concn. and that of B. juncea on Pb was bigger. The root tolerance index of the 2 kinds of plants in the treatment of 3000 mg/kg lead ion was less than 1 and that in the other treatments were above 1. The enrichment coefficient of the root of the 2 kinds of plants in each treatment was bigger than that in aerial parts and the enrichment ability of B. juncea was bigger than that of M. sativa. The content of Pb in root and aerial parts of the 2 kinds of plants all had significant linear correlation with the addition of Pb in soil.
