Over the past decade, scholars in academic fields worked to explore KANG's works in the literature-oriented way instead of the dogma theory of the Soviet Union, and gained extraordinary achievements in positioning KANG's prose status in literature, in estimating aesthetic value of his poetry, in academic contention on three "Legendary Books", and in its effect on the construction and development of modern literary aesthetics theory, but question of simplicity and absoluteness still exist in analysis of the specific text.

近十年来，学术界在探讨康有为学术著作的过程中，打破了苏联的教条理论，回归文学本位，树立以作品为中心的研究格局。在康有为的散文文学定位、诗歌创作的审美价值、关于三大"奇书"的学术争鸣和对近代文艺美学理论的构建和拓展等方面，都取得了不凡的成果，但对具体文本的分析依然存在简单化和绝对化的问题。

In the work, employing a function with four undetermined parameters to model the source wavelet, an analytical relation between Q-factor and envelope peak instantaneous frequency is derived from the theory of one-way waves propagating in an anelastic medium; at the same time, a method for extracting instantaneous frequency in wavelet domain is developed for improving the precision and anti-noise performance of IF estimation, and based on these, a method called EPIF in wavelet domain is proposed for estimating Q-factor of VSP data.

本文采用一个具有4个待定参数的函数去逼近震源子波，利用黏弹介质中单程波传播理论推导出了地震子波包络峰值处瞬时频率和品质因子之间的解析关系；同时，为提高瞬时频率的估计精度和抗噪性能，在小波域中发展了一种计算瞬时频率的方法，并在此基础上提出了估算VSP资料Q值的方法，简称小波域包络峰值处瞬时频率法。

文摘：根据天然放射性衰变系列的平衡关系，推出了通过若干个而非全部放射性组分的监测数据来计算铀矿石和固体废弃物中放射性活度的公式，给出了临沧铀矿退役治理工程的估算实例。

According to the characteristics presented by armed helicopters during cruising or searching for ground targets, this paper has established the mean-square deviation stationary random model of helicopter tracks. It is an important method to decorrelate the measure noise by estimating the parameters of the color noise online. Kalman filtering and forecasting have been made with helicopter tracks. The simulated study has been carried out on helicopter tracks under the condition of color noise. It is very difficult to get an accurate and reliable prediction when the data is very limited. The paper make use of the theory of grey system to resolve the problem of prediction of helicopter tracks, establishing the GM model of grey systems and the cumulative residual error model of n degree, then correcting the GM forecast model. In the period of sampling, GM model and residual error model have been established on line to improve prediction precision.

结合武装直升机在巡航或搜索地面目标的特点，给出直升机航迹模型为协方差平稳随机模型，在线估计有色噪声参数，对测量噪声去相关，对直升机航迹进行卡尔曼滤波与预估，最后对有色噪声条件下的航迹进行了仿真研究；在数据非常有限的情况下，准确地预测又很困难，本文提出了用灰色系统理论解决直升机航迹预测问题，建立了灰色系统GM预测模型和n次累加残差模型并对GM预测模型进行修正，在每个采样期间内，实时在线建立GM预测模型和残差模型以提高预测精度。
