Results The tinnitus frequency, severity of subjective tinnitus, audiogram types and some items of function test above hearing threshold were significantly different in the five groups (P.05). Specific features of pure-tone test were found in the five groups: tinnitus frequency was low, whole- frequency hearing threshold high, audiogram even, short increment sensitivity index at 1 kHz high and tone decline at 4 kHz low in the syndrome of invasion of wind-heat; tinnitus frequency was high, high-frequency hearing loss common, audiogram abruptly descending, SISI and TD at 4 kHz high in the syndrome of liver-fire up-stirring; subjective tinnitus was loud, audiogram abruptly descending or gradually descending, SISI and 7W at 4 kHz low in the syndrome of stagnation of phlegm-fire; tinnitus frequency was high, subjective tinnitus low, audiogram markedly descending or hill-like, SISI and TD at 4 kHz high in the syndrome of kidney-essence deficiency; average hearing loss was less, audiogram irregular but abruptly descending or notched in most cases, SISI at 4 kHz low in the syndrome of weakness of spleen-stomach.

结果］耳鸣频率、自觉耳鸣程度、听力图类型及部分阈上功能测试指标在各证型间具有显著性差异(P.05)，这些指标在不同的证型中表现出不同的特点：风热侵袭型的耳鸣频率较低，全频听阈升高，听力图多为平坦型，短增量敏感指数得分在1kHz较高，而4kHz音衰值较低；肝火上扰型的耳鸣频率较高，听力损失以高频为主，听力图多为陡降型，4kHz SISI得分及TD值均较高；痰火郁结型的自觉耳鸣响度较大，听力图以陡降型或缓降型为主，4kHz SISI得分及TD值均较低；肾精亏损型的耳鸣频率较高，而自觉耳鸣响度较低，听力图以显降型或山型为主，4kHz SISI得分及TD值均较高；脾胃虚弱型的平均听力损失较小，听力图无一定规律性，但以陡降型或切迹型为主，4kHz SISI得分较低。

It will take 56 to 63 days for the frist generetion of Asiatic corn borer to develop from egg to larva, pupa, and imago in Dewu region. 7. The primary imperilment period of first gemeration of Asiatic corn borer is shooting stage. And the heading stage, grain filling stage in early sowing corn and belling stage in late sowing cron is disserved by the second generation. The imperilment degree of second generation is more serious than frist generation. 8. The best way for the prevention of black cutworm is to spray on early larva and to trap and kill with poison bait in late larva.

7第一代玉米螟主要为害拔节期玉米，第二代玉米螟主要为害处于抽雄吐丝期、灌浆期的早播玉米和处于大喇叭口期的晚播玉米，第二代玉米螟对玉米的为害程度显著高于一代玉米螟；玉米螟的为害受玉米品种影响较大，自交系苏宁三号的受害程度明显高于其他各品种；植株长势对玉米螟发生为害程度有极显著影响，表现为长势好、生长旺盛的玉米受害重，长势差的玉米受害轻；海拔高低对玉米螟发生为害的影响不大。

The result showed that the one-valence cationsaccelerate the hydration process of α-hemihydrate gypsum greatly because they improvethe dispersed degree of α-hemihydrate gypsum particles due to the remarkable effect ofincreasing theζpotential; the effects of bivalent and trivalent cations on ζpotentialdecrease in turn, compared with monovalent cations, the effects on both the disperseddegree of α-hemihydrate gypsum particles and the setting time of paste are little.

研究还表明：由于一价阳离子能较大程度地提高石膏浆体的ζ电位，因而有效地提高了石膏颗粒的分散程度，对α半水石膏的水化加速作用很大，而二、三价离子对石膏浆体的ζ电位影响依次减小，对半水石膏颗粒的分散程度和浆体凝结时间的影响均不如一价阳离子作用大。

In the action of Dimilin, the diversity levels of Lepidoptera and Orthoptera insect of the treatment plot had a certain degree decline, and the diversity degrees of Hymenoptera insect and spider had a large increase, thus insect community in the treatment stand tended to be relatively stable.

在时间过程中，施药区鳞翅目和直翅目昆虫的多样性水平有一定程度的下降，但下降程度不如对照区大，膜翅目和蜘蛛的多样性水平则有较大程度的上升，因此林内昆虫群落趋于相对稳定。

High altitude region is more srious than low region. The armyworm imperilment degree varies in different crops. The field planted wheat as forcrop is serious. Also, different levels of cultivation management have evident effects on the imperilment degree of armyworms. For instance, the fields of rough management and bad crop growing suffered more serious imperilment than those of high quality management, intensive cultivation and good crop growing way.

5海拔高低不同，粘虫为害程度有显著差异，表现为高海拔地区较低海拔地区受害重；不同作物对粘虫发生为害程度影响较大，表现为前作为小麦的玉米受害重；耕作管理水平对粘虫发生为害程度有显著影响，表现为管理粗放、长势差的地块受害最重，而管理水平高，精耕细作，长势良好的玉米地受害轻。

According to the models of land use dynamic change, the research on the dynamic change on land use quantity, space structure and land use degree were carried during 1989 and 2001. The results of the research indicated that the area of cultivated land and saline land increased, and the area of meadow, water areas and wetland reduced within 12 years; The variety ratio of cultivated land, meadow, water areas and saline land changed relatively great; and variety ratio of forestland, land used for resident, industrial and mining changed more steady; The land use degree presented a reducible tendency.

研究结果表明，吉林西部在12年内耕地和盐碱地面积增加，草地、水域和湿地面积减少；总体上，耕地、草地、水域和盐碱地的土地利用变化率较大，林地、居民、工矿用地和湿地变化较平稳； 12年间土地利用程度呈减小趋势，全区十个县市中只有白城和扶余的土地利用处于发展期，土地生态环境相对较好，而其他地区由于土地生态环境呈现不同程度的恶化，导致可开发利用的土地资源逐年较少，土地利用潜力小。
