等倾斜的

Imamura (Ref. 1 , p. 346), a well-known seismologist, wrote as follows in 1937:" attacked with every resource at their command the various problems bearing on earthquake prediction, such as earth tiltings and earth pulsations, variation in the elements of terrestrial magnetism, variation in underground temperatures, variation in latitude, secular variation in topography, etc., but satisfactory results were not obtained".

Imamura〔参考文献26第346页〕，著名的地震学家，1937年写道∶'［委员会］利用他们能够调动的一切资源对地震预测有关的所有问题进行研究，包括地倾斜、地跳、地磁因素的变化、地下温度的变化、纬度的变化、地形学方面长期，等，但是未能获得令人满意的结果。

Although these combined relative error γ.1%, in order to obtain more precise measurement results, it should be pay attention for the level of the torsion pendulum, the uprightness between the photoelectric doors and the block rod, the location of the being measured substance, the similarity of the shape and the quality between the standard object and the being measured object, human factors and so on.

利用扭摆法测量物体的转动惯量，受到待测物体摆动周期测量误差、装配位置偏移误差和轴线倾斜误差的影响，虽然这些相对误差总合γ。1%，为了使测量结果是加精确，实践中应该注意扭摆的水平、光电门与挡光杆的垂直、待测物重心的位置、人为误差的影响以及待测物与标准件形状、质量的相近性等。

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。
