正弦双曲线

Results show that parabola is the most suitable one for the displacement-based method, following with cosine curve being the second and then circle the third,while hyperbola is unfit for the method.

认为抛物线最适合在位移法中使用，正弦曲线次之，圆曲线要有所限制，而双曲线则不宜采用。

According to the definition of hyperbolic sine, flow stress constitutive equations of T122 and T91 steels had been developed.

根据双曲线正弦函数的定义，建立了T122钢和T91钢热变形条件下流变应力双曲线本构方程的显式表达式。

Inverse hyperbolic sine -- in radians !!!

反双曲线正弦--以弧度为单位！！！

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。
