查询词典 soil conservation

The results showed that tillage had stronger compaction effect on Red soil. By analyzing retention properties, water content was higher in the same suction for Red soil. Field capacity and wilting coefficient were higher for Red soil than those for Lou soil, but effective moisture and saturated hydraulic conductivity were lower for Red soil. For Red soil, Lateral infiltration ability was stronger, infiltration rate was greater than one number degree for Lou soil and preferential flow occurred easily.

Chapter two proposes the unified form of Hojman"s conservation law and Lutzky"s conservation law. Firstly, the author introduces the general Lie group of transformations that the variations of both the time and the generalized coordinates are considered, derives the determining equation of Lie symmetry for the system, presents a new conservation law, which contains the Hojman"s and the Lutzky"s conservation law as two special cases, and obtains a condition to exclude trivial Hojmans conserved quantities.

第二章，Hojman定理和Lutzky定理的统一形式：首先，引入一般意义下的Lie变换群(即位型变量q_s和时间变量t同时变换)，给出系统的Lie对称性确定方程，提出一个新的守恒律，Hojman定理与Lutzky定理则分别是这个新守恒律在两个特殊情况下的推论，导出一个可排除平凡Hojman守恒量的定理，并分别讨论了Birkhoff系统和非完整系统的Lie对称性和Hojman守恒量，最后，讨论了Hamilton系统的梅对称性与Lie对称性的关系，给出了由梅对称性求Hojman守恒量的方法。

P12 The find of Compton effect and the coherence of theoretical analysy and experimental result not only convincingly veified that the photon theory was right,but also veified that the conservation of energy and the law of conservation particles would similarly observe the law of conservation of energy and the law of conservation of momentum with vigour when they act on each other

康普顿效应的发现，以及理论分析和实验结果的一致，不仅有力地证实了光子学说的正确性，同时也证实了在微观粒子的相互作用过程中，同样严格地遵守能量守恒定律和动量守恒定律。

In "the National Project on Wildlife Protection and Nature Reserve Construction" carried out by the State Administration of Forestry of China, pheasants are among the 15 groups of animals and plants which have high priority for conservation. In this paper, the species diversity, endemic species, and distribution patterns of Galliformes in China are introduced, and the current status and threats to this group of birds are summarized. Base on achievements made in in situ protection, ex situ conservation and scientific research, the main problems existing in conservation practice are discussed, and a conservation strategy for Chinese Galliformes is suggested.

To put it briefly, they think water and soil conservation only make soil, stone and dreg fixed, in another word, not allow it take place displacement, it doesn't deeply prevent land from degrade in the land care that make the guidelines of the projects, the measure adopt in water and soil conservation, etc.

简单的说，认为水土保持仅仅是把土、石、渣固定下来，即不让其发生位移，没有深入到防止土地退化方面的土地保育，使得方案的指导思想、采用的水土保持措施等与水土保持的根本目的相去甚远。
