Actually, the development of genetically-modified products is a double-edged sword: On the one hand, it contributes to the enhancement of the world crop yield, as well as the quality, and reduction of chemical fertilizer and the pesticide use, helps solution of the famine and undernourishment in developing countries. Besides, it also promotes the development of certain related industries like pharmaceutical and chemical industries; On the other hand, it also brings the unprecedented threat for human beings. We are unaware of the potential effects in human bodies, or any unknown injury to the next generation, caused by genetic modification. Nor can we forecast what kind of influence to the extant gene will emerge.

而事实上，转基因生物技术的确是一把双刃剑：一方面，转基因技术可以提高世界农作物产量、提高质量、减少化学肥料和杀虫剂的使用、解决发展中国家的粮食缺乏、饥饿和营养不良的问题，另外，基因技术的飞速发展在很大程度上也促进了医药、化工等相关行业的发展；另一方面，它也为整个人类带来了前所未有的威胁，人们无法得知基因序列的改变会在体内引起何种潜在的变化，无法确定转基因产品是否会对下一代产生任何未知的伤害，无法预测转基因产品对现存基因会产生何种影响。

The chemical shifts and concentrations of the metabolites in the serum were measured in serum samples with pH varied between 7.0 and 7.8. It was demonstrated that, from pH 7.0 to pH 7.8, the chemical shifts of many low molecular-weight metabolites drifted upfield and the intensities of phenylalanine, tyrosine, histidine, and lactate in the T 2-weighted NMR spectra changed significantly.

实验结果表明 pH的改变不仅能够引起血清中一些小分子代谢物化学位移的改变，还会影响小分子代谢物与蛋白的相互作用，引起这些小分子结合态和游离态含量的变化。

In this paper, the progresses acquired in the studies of natural analogy are summarized, including a comparison of structural properties, radiation damage and chemical composition between uraninite and UO2, combination and paragenesis of alteration products of uraninite, chemical composition of uraninite and its secondary phases, mobility of analogy elements in the process of uraninite alteration. In addition, the problems in next studies are pointed out, e. g., characterization of micro-structure of secondary uranium minerals, high-resolution analyses of trance elements distributed in original and secondary uranium minerals using laser microprobe analyzer, composition of underground water, simulation experiments.
