滑块制动器

The mechanical leveling system can realize accurate leveling of the platform by servo-motors and drive system, braking by motor brake (worm and worm wheel system features self-locking) to permanently lock the support system after leveling. Bellows outside outriggers functions sealing and dust-proof of the screw rod; guiding slide blocks are used to prevent screw rod from rotating; displacement sensors installed inside drive system deliver real-time information to determine platform height; load cells deliver data of loading conditions of every outriggers in balancing.

平台机械调平系统通过伺服电机、传动系统可实现对平台的精确调平，并通过电机制动器制动（蜗轮蜗杆系统也具有自锁特性），对调平后的支撑系统进行长期锁定；支腿外部的波纹管可实现丝杠的密封防尘；支腿上部的导向滑块可防止丝杠自转；支撑驱动系统内部安装的位移传感器随时传递信息确定台面的高度；荷重传感器为平衡各支腿的受力状态传输数据。

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.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
