这种形式的肺癌肿瘤扩散速度快，所以通过手术移除肿瘤的可能性极小。
With this form of lung cancer, tumours spread quickly so it is rarely possible to remove the tumours surgically.
戴维斯说，生命变体形式——特别是极小的微生物——可能就出没于“我们的鼻子底下甚至鼻子里”。
Davies said the variant life forms - most likely tiny microbes - could still be hanging around "right under our noses - or even in our noses."
在局限下极大化的假设下，竞争形式的选择一定是基于交易费用的局限下极小化的。
Under the postulate of constrained maximization, the choice of the form of competition is always a result of constrained transaction cost minimization.
本文主要利用拓扑度理论中的不动点定理和变分方法中的极小作用原理及其环绕形式的临界点定理在适当的条件下讨论了一类二阶椭圆边值问题的可解性。
The aim of this thesis is to study the existence of weak solutions for semilinear second order elliptic boundary value problems under suitable conditions through topological and variational methods.
