摘要讨论非线性连续联想记忆神经网络平衡点局部指数稳定的判定条件及平衡点指数吸引域的估计，得到了平衡点局部指数稳定的充要条件，并引入一个特征函数，可以判定平衡点的邻域是否为指数吸引域。

During aging, Gastel index which is sensible to aging condition decreased with increase of aging temperature and aging time. As the same time, the exponential relationship between the change of viscosity and aging time was discovered. Both the gastel index and the aging index can be used to evaluate the aging resistance of the colored paving asphalt.

彩色沥青老化过程中，沥青胶体不稳定指数对沥青老化条件很敏感，随老化温度的升高和老化时间的延长而增加；粘度随老化时间的延长近似呈指数关系增加，所以可以用胶体不稳定指数和老化指数来评价彩色沥青的老化性能。

In present, the discussions of EB estimation are almost all about to exponential distribution family and truncated distribution family, but linear exponential distribution is not exponential family and truncated family, thus, Empirical Bayes estimation for parameter of linear exponential distribution are studied in chapter 4 and chapter 7 that is new aspect.

当前对经验Bayes估计的讨论，大多是对指数分布族以及截断分布族的，线性指数分布即不属于指数分布族也不同于截断型分布族，因而在论文的第四章和第七章研究线性指数分布参数的EB估计是具有一定的新颖性的。

The medullary index interval of hairs from the back, the abdomen, the neck and the hip of chinese muntjac was between 60.5% and 84.5%, the same index in black muntjac was between 62.8% and 80.2%, in white lipped deer was between 60.1% and 90.2%, in roe deer was between 85.8% and 93.2%. Scale pattern is simple in four kinds of deer, mainly including irregular wave type, flat type, inlay type and coronal type, etc. Their sequence is different.

It was shown that there was obvious changes in the RBC's deformation and orientation in the senescent models.

结果：对新生红细胞的压积、变形指数、取向指数等指标的连续60多天的监测，发现红细胞在整个衰老过程中的变形指数和取向指数有明显改变。

Tree ring width of diseased trees and healthy trees showed significant difference.

杨树的年轮宽度与树龄有极好的指数相关性，采用比值法求得年轮宽度指数，健康材的年轮宽度指数均接近 1 ，受害材的年轮宽度指数偏低。

There were only 94 vascular plant species, belonging to 50 family and 75 genera. The dominant species in the communities were deciduous broadleaf species Liquidambar formosana, Robinia pseudoacacia, Ailanthus altissima, Acer buergerianum, and Celtis sinensis, evergreen broadleaf species Cinnamomum camphora and Elaeocarpus glabripetalus, and Phyllostachys heterocycla. Robinia pseudoacacia+Cinnamomum camphora community had the highest Shannon-Wiener index (1757) and Phyllostachys heterocycla+Acer buergerianum community had the highest Simpson index (0163), but no consistency was observed between the curves of H and D. For vertical structure, most communities had no significant understory stratification.

结果表明：辰山植物区系以泛热带和北温带占优势，具有典型亚热带和温带成分交汇和南北植物分布交错特征；但保育区内种类单一，维管束植物仅有49科69属94种；主要群落是以枫香、刺槐、臭椿、三角枫和朴树等为优势树种的落叶阔叶林，以香樟和秃瓣杜英等为优势树种的常绿阔叶林，以及毛竹林；物种多样性普遍较低，Shannon-Wiener多样性指数最高为刺槐+香樟群落（1.757），Simpson均匀度指数最高值为毛竹+三角枫群落（0.163）；多样性指数曲线和均匀度指数曲线不具有一致性的变化趋势；多数群落垂直结构中无明显林下分层现象；演替前期的落叶乔木种群后续个体不足。

The result makes clear: 1 index of pressure of Chinese farmland zoology is older, be in ascendant trend, its are main the reason is our country farmland the area decreases in great quantities continuously and population increases;2 farmland pressure quickly to save time difference bigger, the farmland pressure of southeast and southwest is apparent prep above is mid with heighten of grade of index of pressure of zoology of farmland of municipality directly under the Central Government of upper zone;3 and southeast ministry area, upper, northwest and mid major area exponential grade is invariant, only mid with the decrescent of grade of index of a few district, but not apparent.

结果表明：1近11年的中国耕地生态压力指数比较大，并处于上升趋向，其主要原因是我国耕地面积持续大量的减少和人口快速的增加；2耕地压力省际差异比较大，东南和西南地区的耕地压力明显高于中部和北部地区；3直辖市和东南部地区耕地生态压力指数等级增高，北部、西北和中部的大部分地区指数等级无变化，仅中部和东北部的少数地区指数等级变小，但并不明显。

One hundred and fifteen species were identified, among which coastal eurythermic species were predominant, showing obvious characteristics of subtropical population fauna. The results showed that the average abundance of phytoplankton in Shacheng Harbour was 3113.24 ind·L-1. The abundance was higher in the inner bay than that in the outer bay in horizontal distribution. The surface abundance was a little higher, but there was no significant gradient in different water layers in vertical distribution. Shannon-Wiener diversity index, Margalef richness index, Pielou evenness index and Simpson dominance index were 2.390, 2.650, 0.726 and 0.306, respectively.

结果表明，该次调查共出现浮游植物115种，种类以沿岸广温广盐性种为主，并呈现较为明显的亚热带海湾种群区系特征，浮游植物的平均丰度为3 113.24 ind·L-1；水平分布上，呈内湾高于外湾的格局；垂直分布上，表层丰度略高，不同水层的分布梯度不明显；Shannon-Wiener多样性指数、Margalef丰富度指数、Pielou均匀度指数和Simpson优势度指数分别为2.390、2.650、0.726、0.306。

The results showed : thymus, Bursa, Harderian gland and spleen weight increase with age, gradually increasing; Thymus index, Bursa index and Harderian gland, the index increased with age gradually and the spleen index increase with age in the first increased and then decreased.

结果表明：胸腺、法氏囊、哈德氏腺和脾脏的重量随日龄的增长，逐渐增大；胸腺指数、法氏囊指数和哈德氏腺指数随日龄的增长逐渐变小，脾脏指数随日龄的增长，先增加后减小。
