This error can be as much as 10 C, depending on melt viscosity and flow rate. Normally, this is usually ignored as most extruders are more interested in comparative readings than absolute ones, but for the chemical reactions like cross-linking or foaming, a more exact value may be needed, and the amount of shear heating may need to be known. It is a relative simple thing to do - when the machine is to be shut down, stop the screw without reducing speed or barrel conditions and watch the drop in melt temperature over the first 10-20 seconds, or until it begins to level out again.

通常在大部分关注相对读数的挤出机上，这些偏差可以忽略；但如一些挤出反应如交联、发泡对反应温度要求精确，剪切产生的热量需要知道，有一个相对比较简单的办法：但关闭机器的时候，并不降低主机转速或者筒体温度，在第10-20秒时，或者直到熔体温度达到平衡时，观察熔体温度下降了多少。

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。
