To study the effect of thermal deformation parameters such as punch velocity,forming temperature and forming load on forming process of 5A02 aluminum alloy microgears,a microdie is designed and fabricated and pressing ratio is used as evaluation parameter to indicate compactness.

为了研究凸模速度、成形温度和成形载荷等热变形参数对5A02铝合金微型齿轮成形的影响规律，设计制造了微型齿轮模具，在自行研制的微塑性成形设备上，将压入高度比作为填充程度的评价参数进行了成形实验，成功获得了质量良好的节圆直径为Φ1 mm的5A02铝合金微型齿轮。

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.
