Results 1 there were no significant differences of amplitude of accommodation and accommodative lag between the myopia group and emmetropia group. The differences of amplitude of accommodation between the myopia group and hyperopia group were significant (t=2.21, P=0.03.05; t=2.83, P=0.006.05). 2 The difference of accommodative lag between the dominant eye (0.73±0.31) D and non-dominant eyes (0.81±0.38) D in myopia group was signiflcant.3 The accommodative lag of dominant eyes was (0.68±0.36) D and it of non-dominant eyes was (0.75±0.34) D, the difference was significant (t=2.06, P=0.042.05, n=95).There was no significant difference between the amplitude of accommodation of dominant eye (12.9±3.09) D and non-dominant eyes (12.6±3.09) D.

Then the dominant species of each season was identified and the contribution of the abundance of these dominant species to total abundance was analyzed. The results indicate an obvious succession of dominant species. Centropages dorsispinatus, Acartia pacifica ca and Sagitta enflata were the primary dominant species in summer, however, Paracalanus aculeatus, Acartia pacifica and Paracalanus crassirostris were the major dominant species in autumn.

Zantedeschia aethiopica constructed wetland system has high COD and N removal rate in dominant period than in vigorous period, caused by the high temperature in dominant period. Low TP removal rate in dominant period than in vigorous period caused by the following reasons, first the decay of litter in the dominant period is obvious, and the high inflow rate in the dominant period.

马蹄莲人工湿地系统在休眠期（6月和7月）和在旺盛生长期相比，由于温度高而具有高的COD，和N去除率，由于枯枝落叶的腐烂溶出以及进水负荷高而具有低的TP去除率。

In the presently mobile position technology, GPS's position method is one of the best. This method owns high accuracy less than 15 meters, and can be used with GPS chip in the mobile station. But GPS chip with the high price makes this technology difficult to popular. Therefore, the position technology of GSM communication network is attention to the people gradually. TOA or AOA is more often used among position technology, these methods need only the help of the position measuring instrument to attain time and angle for position calculation. They have good position accuracy, but they are also too expensive to popular. Every positioning technology has its bottleneck such as external environment influence, cost and positing efficiency. Therefore, the purpose of this research lies in finding out the mobile station location and does not emphasize the raise of the accuracy and it only uses existing information to finish position action.

在目前的行动定位技术中，以GPS定位技术为最佳，不仅拥有少於15公尺的高定位精确度，更只需在行动端加装GPS晶片即可使用，可惜高价格的GPS晶片使得此技术难以普及化，因此，以GSM通讯网路为主的定位技术逐渐受人们所重视，其中，又以TOA或AOA等定位技术较常被使用，仅透过位置测量仪器的帮助，便可取得定位所需的时间和角度，并且拥有不错的定位精确度，可惜也受到高价格因素的关系难以普及化，而每种定位技术都有其瓶颈存在，不论是外在环境的影响、成本和定位效能上；所以，本研究的目的在於找出行动端位置，即利用现有的资讯（细胞识别码、讯号强度等）来完成定位动作，而非强调其定位精确度的提高。

Numerically, Limacina trochiformis was the main dominant specis in spring, attributed to its low temperature adaptation. Atlanta peroni was the dominant species in summer and Creseis acicula was the dominant species in autumn due to their adaptation to relatively high temperature. Agadina stimpsoniji was the dominant species in winter, adapted to low temperature.

Sp. tritici of the F1 plants were tested at the seedling and adult stages. The results indicated that dominant and semi-dominant genes were responsible for powdery mildew resistance at the seedling stage, while dominant, semi-dominant and recessive genes were found controlling the powdery mildew resistance at the adult plants. After testing the Pm30 linked SSR marker Xgwml59 on the 40 F1 hybrids between wild emmer and common wheat, it was found that the Pm30 linked Xgwm159 loci could be detected at 8 F1 hybrids, indicating the 8 wild emmers might also carry the Pm30 gene.

The issues of present seismic wavelet frequency caused by different concepts, such as apparent frequency, dominant frequency, peak frequency and centroid frequency, etc., which are defined by different methods, and understanding deviation, definition of seismic wavelet frequency for time and frequency domain are concluded and summarized. On this basis, three kinds of seismic wavelets in common use such as Ricker and Zinc wavelets as well as sine wavelet with exponential attenuation characteristics are analyzed and a conclude is achieved that apparent frequency and dominant frequency are consistent in essence, but peak frequency and centroid frequency as well as apparent frequency or dominant frequency are not completely consistent with different seismic wavelets. For actual seismic data, peak frequency can approximately be used as dominant frequency, but it is not suitable when seismic wavelet is known for it can give out any wrong knowledge and results.

针对目前地震子波频率由于定义方式出现的各种概念（视频率、主频、峰值频率、中心频率等）以及理解上出现的偏差等问题，首先从时间域定义和频率域定义2个方面进行了归纳和总结，并在此基础上对3种常用地震子波（Ricker子波，Zinc子波，正弦指数衰减子波）进行了分析和研究，得出视频率与主频概念一致，但不同地震子波的峰值频率、中心频率和视频率之间并不完全一致的结论；而对于实际地震资料，将峰值频率近似看作地震子波的主频是可以的，但在地震子波已知的情形下这样做是不恰当的，甚至可能会得出错误的结论和认识。

In order to realize the optimization of product combination effectively, it is important to correctly distinguish dominant product, forerunning product and line of dominant products. In this dissertation, we build a model to cognize the dominant product, forerunning product and line of dominant products on the base of statistic theory.
