We prepared bulk samples of metastable solid solutions with bcc and fcc structuresin the Fe-Cu system by using shock compression with mechanical alloying, and the magnetization and valence electron were measured and calculated. The saturation magnetic-moment curve versus mumber of electrons per atom at 0K was found to be reasonably similar to the-electrons/atom curve of other transition-metal binary systems.

用机械合金化锻压方法制备了bcc和fcc结构的块状亚稳态Fe-Cu固溶体系统，并对系统的磁化强度、价电子结构进行了测量和计算，从亚稳态 Fe-Cu固溶体的饱和磁化强度Ms-e/a曲线可看出：大约在26.2e/a的区域Ms有最大值，并且在大约28.6e/a的区域接近零。

According to the Hong Kong paper 蘋 fruit daily report, the construction cost 3,500,000,000 origin (approximately 55,000,000,000 Yen) the nest of the bird which is thrown,unless every year 50,000,000 origin (approximately 800,000,000 Yen) cost of maintenance above is applied, is danger which the scrap iron is converted instantaneously.

根据香港纸蘋果子每日报告，建筑费3，500，000，000起源(大约55，000，000，000日元)被投掷鸟的巢，除非每年上面50，000，000个起源(大约800，000，000日元)的维修费用是应用的，是瞬间地转换废铁的危险。

For example, the eccentricity changes over time cycles of about 100,000 and 400,000 years, with the value ranging from less than 0.01 up to 0.05.[15][16] This is equivalent to a change of the semiminor axis of the planet's orbit from 99.95% of the semimajor axis to 99.88%, respectively.

例如，离心率大约在小于0.01至0.05之间变动，变动周期大约是10万年至40万年，这相当于行星运行轨道的短半轴相对于长半轴的比例在99.55%与99.88%之间发生变动。

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。
