虚

By this analysis, we can sum up the overall coronary heart disease pathogenesis as "the imaginary superficiality."

通过以上分析，可以总结出冠心病总的病机为"本虚标实"。

Our code can rely on the fact that the list of exceptions in the base class is a superset of the list of exceptions that a derived-class version of the virtual might throw.

代码可以依赖于这样一个事实：基类中的异常列表是虚函数的派生类版本可以抛出的异常列表的超集。

In the view of the system supply, the lack of the university statutes is the one of important root causes.

如果从制度供给的角度来看，大学章程的缺失或"虚位"可以说是高校不和谐的重要根源之一。

The meaning also influences the emergence of suppositional object and understanding of favoring role and favored role.

并可能对虚指宾语的产生和双宾句中施惠受惠角色的理解产生影响。

It's time for you to swoop in!

They have the same meaning but different syntactical function and pragmatic regulation.

比较主体和比较客体在比较点上的相似程度越低，表达虚比的功能就越弱。

A new scheme of target discrimination in SAR images, consisted of frames, models and algorithms, is proposed. Under such a scheme, a global frame, combining orderly the algorithm based on feature extraction and that based on knowledge, is then proposed. Moreover, in the method of target discrimination based on feature extraction, a "loose-coupling" model is given. The existing features are chosen and three new features about the contrast are given under the "loose-coupling". Meanwhile, an algorithm of feature selection based on Genetic Algorithm is also modified to solve the problem that the existing algorithm can not evaluate the goodness-of-features comprehensively. The weighted quadratic distance discriminator is designed to improve the performance of target discrimination. Finally, a method based on the knowledge of target groups to remove clutter false alarms is also given.

提出了一种目标鉴别的新方案，该方案包括目标鉴别的框架、模型以及算法；提出了基于特征选取鉴别和基于编队提取鉴别"序贯"连接相结合的目标鉴别框架；在基于特征选取进行目标鉴别的方法中，提出了目标鉴别的"松耦合"模型；提出了"松耦合"模型下目标鉴别的特征提取方法，包括已有特征的筛选和3个新的对比度特征的提出；改进了一种基于GA的特征选择方法，克服了已有方法对特征优劣评价不全面的问题；设计了加权二次距离鉴别器，提高了鉴别的性能；研究了基于目标编队知识进行进一步杂波虚警剔除的方法。

O Joy that seekest me through pain, I cannot close my heart to Thee, I trace the rainbow through the rain, And feel the promise is not vain, That morn shall tearless be.

你的欢欣透过痛苦来找我，我无法对你关闭心门，我透过雨丝去追寻彩虹，感知诺言非虚，明日必是良辰。
