严重缺陷

• In the algorithm level , currently various training algorithms of neural networks , including gradient algorithms , intelligent learning algorithms and hybrid algorithms , are comparatively studied ; the optimization principle of bp algorithm for neural networks training is analyzed in detail , and the reasons for serious disadvantages of bp algorithms are found out , moreover , the optimization principle of two kinds of improved bp algorithms is described in a uniform theoretic framework ; and the global optimization algorithms of neural networks , mainly genetic algorithm are expounded in detail , it follows that a improved genetic algorithm is proposed ; finally the training performances of various algorithms are compared based on a simulation experiment on a benchmark problem of neural network learning , furthermore , a viewpoint that genetic algorithm is subject to " curse of dimension " is proposed
  在算法层，本文对目前用于神经网络训练的各种算法，包括梯度算法、智能学习算法和混合学习算法进行了比较研究；对用于神经网络训练的bp算法的优化原理进行了详细的理论分析，找到了bp算法存在严重缺陷的原因，并对其两类改进算法-启发式算法和二次梯度算法的优化原理，在统一的框架之下进行了详尽的理论描述；对神经网络全局优化算法主要是遗传算法进行了详细的阐述，并在此基础上，设计了一种性能改进的遗传算法；最后基于神经网络学习的benchmark问题对各种算法在网络训练中的应用性能进行了仿真研究，并提出了遗传算法受困于“维数灾难”的观点。

  它克服了传统绩效评价体系普遍只注重财务方面指标而忽视非财务指标的严重缺陷，能主要通过财务方面、顾客方面、内部经营过程方面和学习与成长方面等四个重要角度全面科学的对企业真实业绩进行综合评价。
• But at the same time , our social security system is imperfect , especially the social assistance system , which lead to some city low - income families " hard lives , impede the economic development . the reforming process , and affect our society ' s peace
  但同时社会保障体制不健全、不完善，尤其是在整个社会保障体系中起“兜底”作用的社会救助制度严重缺陷，使一部分城市低收入家庭难以维持生计，阻碍了经济发展和改革进程，引起了社会动荡，影响了社会安定团结。
• At the present time the prediction method of attracting pest with black light and recognizing and counting by man is generally adopted . there are some serious shortages such as bad recognition accuracy and low efficiency . it reduces seriously accuracy and timeliness of prediction and is disadvantage in guiding insect disease prevention
  目前普遍采用的黑光灯诱集害虫、人工识别计数的测报方法，存在识别准确性差、效率低等严重缺陷，极大地降低了测报的准确度和时效性，不利于指导农田害虫的防治工作，因此本文提出了基于机器视觉和小波分析的图像识别技术，用于农田害虫的自动检测预报。
• For example , obstacles appear in their emotions and spirits , they are not adaptable , they have serious defects in their dispositions , they study with great difficulty and their sociability develops unhealthy , and so forth . comparing these problems to the children from integrated families , the writer finds out the differences and pave the way for the following writing
  笔者首先简要阐述中西方国家离异家庭及其子女的现状和小学生在父母离婚后表现出来的一系列心理问题，如情绪情感出现障碍、适应性差、性格严重缺陷、学习困难、社会性发展不良等，并把这些问题与完整家庭子女做比较，找出问题差异。
• The second chapter " the current situation of chinese reorganization law " centering on the content of the current chinese reorganization law , mainly analyzes the institution design and enforcement effect of the chinese reorganization law , and comes to the conclusion that the current chinese reorganization law has great defect in theory and practice and cannot meet the demands of the market economy
  第二章“中国破产重整立法现状”围绕中国现行破产重整法律规定，着重分析其制度设计和实施效果，从而得出结论：现行破产重整法律制度无论从理论还是实践角度看都存在严重缺陷，无法适应建立市场经济的要求。
• Combining increasingly great challenge to organization and its management in the hyper - competitive networked environment , main problems and deficiencies of organizational innovation and its management of chinese manufacturing enterprises , and the limitations of prior research work in this area , this chapter puts forward a fundamental question to be answered by this thesis , its including three basic ones , and four specific ones , and presents the research aims
  综合研究背景中所阐述的超竞争网络环境对组织管理提出日益严峻挑战、企业组织创新及管理实践中所存在的根本问题和严重缺陷，以及国内外现有研究的不足之处提出本研究所要回答的一个根本问题、三个基本问题和四个具体研究问题，进而确定研究目的。
• A business operator which finds a commodity or a service provided by it to have a serious defect which may cause harm to the safety of person or property of the consumer , even where such a commodity or a service is used correctly , must immediately make a report to the relevant authorities , inform consumers and adopt preventative measures against such occurrence
  经营者发现其提供的商品或者服务存在严重缺陷，即使正确使用商品或者接受服务仍然可能对人身、财产安全造成危害的，应当立即向有关行政部门报告和告知消费者，并采取防止危害发生的措施。
• Because the technological development course of the computer and restriction of other objective conditions in the campus , many kinds of c / s framework coexists at the same time . because it is a relatively independent course that every departments build step by step in the campus at the same time and the information stems from the database of the traditional information subsystem , the information sharing is limited , the data exchange lacking and the information one inconsistently have caused the serious defect of the system
  由于计算机技术发展历程和校园内其他客观条件的限制，造成多种c s架构的系统在校园中同时并存，同时由于校园内资源建设客观上是各部门相对独立的一个渐进建设过程，而这些信息来源于传统的信息子系统的数据库，信息共享有限、数据交换缺少和信息的不一致，导致系统的严重缺陷。
