必要条件

More specifically, it is intended to elicit the necessary and sufficient conditions for such an argument to go through.

更明确的，是要引出执行这种论证的充分和必要条件。

The Specific Work Experience category is not part of the eligibility requirements.

特定的工作经验不是必要条件的一部分。这样说对吗？

Nonlinear flexural wave equation is solved by the Jacobi elliptic function expansion method. Two kinds of exact periodic solutions of the nonlinear equations are obtained, that is, the shock wave solution and the solitary wave solution. The necessary condition for existence of exact periodic solutions, shock solution and solitary solution is discussed, which is consistent with the qualitative analysis.

利用Jacobi椭圆函数展开法，对该非线性方程进行求解，得到了非线性波动方程的准确周期解及相对应的孤波解和冲击波解，讨论了这些解存在的必要条件，这与定性分析的结果完全相同。

The chaotic planar attitude motion of a ligid spacecraft on an elliptic orbit in the gravitational field with air drag and internal damping and its control are studied. The necessary condition of occurring chaos is established by Melnikov's method. A numerical example is presented.

研究了同时存在大气阻力和结构内阻尼的椭圆轨道上平面天平动航天器的混沌姿态运动及其控制，应用〓方法给出了出现混沌的必要条件，用数值算例进行了验证。

energy-efficient building is a necessary condition for economic development.

节能建筑是发展经济的必要条件。

We obtain some sufficient and necessary function conditions for entailment with special properties such as transition and interpolation.

借助函数工具，我们揭示传递律、插入律、way below关系、蕴含一致性等的蕴含函数的充分必要条件。

It is obtained that a fuzzy mapping is convex if and only if the epigraph of this fuzzy mapping is a fuzzy set in R×E.

在此基础上，得到了一个实变量模糊数值映射是凸模糊映射的充分必要条件：这个实变量模糊数值映射的上方图是R×E中的一个凸集。

Like Kant, Stroud considers what makes possible, or what conditions are necessary for, people's even having the thoughts and experiences that any epistemologist's investigation into human knowledge must at the beginning take her subjects to have.

像Kant那样，Stroud也考虑"什么使得'人们拥有思/经验（——任何认识论者研究人之知识，都必须从一开始把这些归给她的主体拥有）'成为可能，或什么是其必要条件"。

In the fourth chapter, we discussion the characterization of admissible in the general linear model under equality constraint and inequality constraint, we give the necessary and sufficient condition that homogeneous linear estimator is admissible estimator, and by using the relationship between homogeneous and inhomogeneous linear estimator, we obtain the characterization of admissible inhomogeneous linear estimator.

第四章分别在带等式约束条件以及不等式约束条件下，讨论了一般线性模型线性估计的可容许性特征，给出了在约束条件下齐次线性估计为可容许估计的充分必要条件，同时利用齐次线性估计与非齐次线性估计之间的关系，把齐次线性估计的可容许性特征推广到了非齐次线性估计的可容许性特征。

The author makes a new exploration about such problems as the Chinese expression and its classification, the basis of true or false judgment, the equivalent expression of the negative proposition of the hypothetical judgment under necessary conditions and the anti-syllogism under the condition that the proposition is used as the premise.

就必要条件假言命题的汉语表达式及其分类、判定真假依据、负命题的等值式，以及以此类命题作前提的反三段论等问题，作出了全新的探讨。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
