其结果分别是：盖度动态变化分析表明：云南狼尾草，非洲狗尾草，东非狼尾草是盖度一直非常高的草种，普通狗牙根和弯叶画眉播种三个月后盖度较高，其次高羊茅的盖度也一直能满足要求。

Begin with an initial triangle, this algorithm growingly searches the satisfied points to form new triangles.

该算法由一个初始三角片开始，扩张式地搜索满足要求的点以生成新的三角片。

First the spectrum-equalized seismic data is equalized by trace, then the result is analyzed with the MESE. If the resolving power of the MESE doesn't reach the precision desire, the equalized data is added with appropriate white noise, then is analyzed with the MESE. Thus the more precise spectral estimate is gotten.

首先对谱均衡后的地震数据作归一化处理，然后对处理结果作最大熵谱估计，若估计结果的谱分辨率精度不能满足要求，则先对归一化的地震记录叠加適当的白噪声，然后再作最大熵谱，这样可以得到较高的估计精度。

This is advantageous to the analysis of the effect of nonstationary characteristics on the structural responses.

最后，进行结构地震时程分析时，输入地震波的确定是基础，仅依靠现有的地震加速度记录往往不能满足要求。

Address the characteristics of non-uniform speed transmission, position function control and transmission ratio function control were presented to realize electronic gearbox. The differences between position function curve interpolation and general NC interpolation were analyzed. Considering the effect of uncontrollable continuous principal motion, interpolation slope and position function precompensation interpolation were presented. The relationship among interpolation, servo dynamic response and transmission precision was studied. The coordinate linkage relationship and electronic gearbox scheme in noncirclar gear hobbing were studied.

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
