查询词典 conservation

We should press ahead with energy conservation and environmental protection.

我们应该积极推进节能和环保工作。

The SCVFV(the convection-diffusion difference scheme based on control-volume face values) scheme was put forward. The theory of the SCVFV scheme was systematically elaborated. The general interpolation formula of the SCVFV scheme was given. The formulas of the SCVFV scheme based on the Cartesian coordinate were derived. The precision, the mass conservation property and the preventability of the false-diffusion of the SCVFV scheme were theoretically analyzed.

提出了基于控制容积面值的对流扩散差分格式SCVFV，系统地阐述了SCVFV格式的基本思想，给出了SCVFV插值公式的通用表达式，推导了直角坐标系下完整的SCVFV格式的表达式，从理论上分析SCVFV格式的精度、守恒性及反伪扩散性。

Based on the capacity of affirming quantity, younger infants are sensitive to number which is the jumping-off point for them acquiring rich preverbal quantitative knowledge. In the early of preschool period, children construct many types of schemas, later they attain the concept of quantity conservation. Besides this conceptual knowledge, children's cognitive skills such as counting also develop rapidly.

基于天赋的"快速确认"数量的能力，较小的婴儿对数字就很敏感，以此为起点他们获得了丰富的前语言的数量知识；在幼儿早期建构了多种数量图式，到幼儿期末形成了数量守恒概念；除了这些概念性知识之外，儿童的数数等认知技能在幼儿到小学初期也获得了发展。
