大自然

The first time I feel their insignificance in the face of disease and natural powerless.

我第一次感到了自己的渺小，在疾病和大自然面前无能为力。

Plant growth simulation algorithm aiming at the global optimization of integer programming is a kind of bionics random algorithm which occurs in nature.

针对整数规划全局优化问题所首次提出的模拟植物生长算法，是一种源于大自然的仿生类随机算法。

The practice of craft is intrinsically the intercommunion between mankind and the immensity of nature.

工艺本身就是人类和大自然间的沟通，这是统一所有艺术与工艺的内在原则。

Your level of happiness is largely related to your level of intimacy with nature.

您的幸福水平的主要是与您的水平，与大自然亲密。

For him, nature and human life are intimately connected.

对他而言，大自然和人生是紧密相连的。

An unfavourable relationship between numbers and resources tends to make the earning of a living almost intolerably difficult.

在个人与不友善的大自然残暴之间，在个人与冷酷无情的政治、经济权力主宰者的残暴之间，不存在积累购买的剩余。民主的力量之一，是可以向老板说

I am also excited, and no one is not for the wonderful natural scenery while intoxicated.

我也同样兴奋，没有谁能不为这奇妙的大自然景色而陶醉。

If we recognize the inverse square law being an optimal controller presented by nature, what is the corresponding actionfor it?

倘若我们假定平方反比定律为大自然的最佳控制手段，试问其对应的行动能量为何？

By using Pontryagin minimal principle to minimize the action, a partial differential equation for the Lagrangian is obtained and solved. For this action, it can be verified directly that the inverse square law is the corresponding optimal controller. Finally, the generalization of this mechanization is presented for more complicated dynamical systems.

此一方程的解虽有无限多组，然其中一组的解为该系统的行动能量是总能量，所显示的物理意义为大自然若采取平方反比定律为最佳控制器，其目的在维持物体沿特定轨道运动的总能量为固定。

Why is it so important to preserve biodiversity. The invertebrate represent 95 % of the living world.

透过景致怡人的亮丽风光，带出为何要保护大自然中多种虫虫生物的重要性；无脊椎动物占了所有生物种类的95%。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
