作者 张彦龙 《养殖与饲料》 2017年第6期26-27,共2页
哺乳仔猪的成活率高低直接关系规模化养猪场的经济效益,故在产房期间抓好仔猪的出生、补料、免疫、断奶,从细节做起,过好仔猪出生关、诱食关、免疫关、断奶关是提高仔猪成活率的关键。

The changes correspond to changes in the birth-rate. The former model of birth-rate which was characterized by the prevalence of legitimate children, child-bearing at a younger age and which ensured a change of generations, it was replaced by a new model characterized by having illegitimate children, the postponement of child-bearing, and low birth-rate, which does not ensure a change of generations. Although love relationships, marriage, and children are still considered to be the recognized values, these changes have affected the conception of child's education in the family and the perception of child as a value. It is therefore relevant to evaluate future spouses' preparation for a modern marriage and to constantly improve it. Such preparation is usually understood as young people's readiness far their first marriage. Readiness for the second marriage and child's education in the second family are no less important though still insufficiently explored empirically and theoretically generalized. This paper explores attitudes to child's education in the second marriage. The research was conducted inquiring people who wanted to create a family or establish long-term relationships. They were members of the online dating site "Harmonious Couple". 展开更多

Based on the input-output relation of the cavity and the Faraday Rotation mechanism, we propose a scheme for generating the n-atom Greenberger Horne-Zeilinger state. In the scheme, the n-atom trapped respectively in n spatially separate cavities would be entangled with the photons going through the atom-cavity system. The successful probabilities of our protocol approach unity in the ideal case. What is more, no requirement for separately addressing further lowers experimental difficulties. 展开更多
