Sep 19, 2009 · Sep 19, 2009. #6. Both are fine with me. I might prefer one over the other based on context. If you are discussing what is happening in the state of equilibrium, then I would prefer 'in.'. If your system unstable and equilibrium is coming and going, then I would choose 'at' for the moment that equilibrium is achieved.
纳什均衡 (Nash Equilibrium) - 知乎. 概念. “纳什均衡“是由美国数学家小约翰·福布斯·纳什（John Forbes Nash Jr），在1950年获得美国普林斯顿大学的博士学位的只有28页的博士论文中提出的一个“博弈论”的概念，根据纳什的说法，“一个纳什平衡点是当其余参与者的 ...
Dec 6, 2002 · 一次行动中，约翰遇到玛丽·欧布莱恩（艾米丽·沃森 Emily Watson 饰）。. 她使得约翰开始断绝药物，试图体会有感情的生活究竟是一种什么样的滋味。. 他被那些第一次出现在他生命里的奇妙动人景象所陶醉了，也深深的为每天履行的破坏艺术的行为感到愧疚和 ...
我在接下来的这篇回答中会涉及到三个重要的均衡概念，Nash Equilibrium，Competitive Equilibrium，以及Lindahl Equilibrium。. 我会简单讲一下怎么从Nash得出Competitive，然后从Competitive得出Lindahl。. 首先我们来给出纳什均衡的定义. 定义1. 假设有n个行为人，每个行为人 i 都有 ...
直接研究非平衡动力学的细节，不论是数学上，思想上还是实证上，都要难上许多，一般人研究不来。. 我们的最终目标当然是把非平衡也理清，但在开始阶段还是必须先探究平衡。. 均衡是数学意义上的均衡，起源于一般均衡模型，这是洛桑学派瓦尔拉斯在 ...
Aug 5, 2020 · Equilibrium in population models doesn't necessarily mean that there is no change. Populations can easily be in dynamic equilibrium, changing all the time but rising and falling around what may be a moving plateau. A clock's pendulum is in a similar sort of equilibrium. Fish populations in a lake sometimes behave like that. The population rises ...
Nov 22, 2015 · That's basically a mathematical description of potential outcomes based on individual strategies, which is useful for decision making, especially in self-learning systems. If you read 'prevalence' as superiority, then "where prevalence is a non-singular event" is actually a paradox because if both parties can have superiority then you cannot ...
本片旨在跟观众们讨论了一个问题，那就是面临着末日审判的时候，强权政治是否能真正的达到统一领导的目的。. 很显然，本片中的这种结合了神学和独裁统治的政治体并不具备这样的能力。. 在讽刺了利比亚之余，片中的暴力机构的最高领袖却是被称之为神的 ...
化学平衡（英语：Chemical equilibrium）是指在宏观条件一定的可逆反应中，化学反应正逆反应速率相等，反应物和生成物各组分浓度不再改变的状态。可用ΔrGm=ΣνΑμΑ=0判断，μA是反应中A物质的化学势。也就是说，化学反应达到平衡状态，意味着生成物的吉布斯自由能G达到最小。理论上来讲，对于 ...
Nov 3, 2020 · Nov 3, 2020. #2. No, it isn't a typo. It's perfectly correct. No sooner ..... than is a very standard, basic construction. You will find it any dictionary or grammar book. It means that the second event happened almost immediately after the first. 'Then' makes no sense at all.
