It was shown that the stable carbon isotope composition of beef tissue was primarily dependent on the diet the animals were fed,meanwhile theδ~(13)C values of cattle tail hair, defatted muscle and crude fat all enhanced with the increment of the proportions of C4 constituents in diet, but those values were on the contrary with the enhancement of the proportions of C3 constituents. Moreover, allδ~(13)C values of different tissues were significantly correlated with the content of C4 and C3 plant material. So, the main component of cattle feed could be investigated with the help ofδ~(13)C values. Theδ~(15)N values of beef tissues were affected by feed composition to some extent, but it had no regularity. The cattle tail hair and defatted muscle enriched in 13C to their feeds gave different results between the two groups, but cattle tail hair enriched in 15N much more than defatted muscle and in the proportion of 3‰- 5‰, plus, cattle variety and individual had effect on the proportion of enrichment.

结果表明，牛组织中碳同位素组成主要受饲料的影响，牛尾毛、脱脂肌肉、粗脂肪中的δ~(13)C值随着C4植物含量在牛饲料中的比例增加而升高，随着C3植物含量在牛饲料中的比例增大而降低，并且均与C4、C3植物含量呈极显著的相关性(P.01)，用牛组织中的δ~(13)C值可以调查牛饲料中的主要成分；牛组织中的氮同位素一定程度上受饲料因素的影响，但未随饲料组成成分的改变而呈现规律性变化；牛尾毛、脱脂肌肉相对饲料对13C的富集比例两组试验结果不一致，牛尾毛对15N的富集比例大于脱脂肌肉，富集比例约在3‰- 5‰，饲料种类、牛个体等因素对富集比例均有一定影响；牛尾毛、脱脂肌肉、粗脂肪中的δ~(13)C值三者之间相关性达到极显著水平(P.01)。

Surprisingly, the lusty leafs of C. wenyujin planted in red soil turn to pale and brown flecks occur in the leafs with the fertilization of N, P, K. It is concluded that C. wenyujin can be planted in lime soil; C.

Based on the description of Mohr-Coulomb and Drucker-Prager yield criteria with invariant of stress, a formula for error estimation of unit strain energy between the two stress states is established in the deviatoric plane of the principal stress space, which satisfies M-C and D-P yield criteria respectively. A general procedure to transform M-C material parameters to D-P analysis parameters is obtained.
