Because the dependent variable in the models is the share of consumption of food , and the models are equation of demand system , therefore , zellner s seemingly unrelated regression method is applied to estimate the models 因为在模型中作为因变量的是食物的消费份额，同时模型是需求系统方程，因而，采用近乎非相关的系统迭代回归法进行模型估计。
The model , on extent , can keep sensitive data safe in most enterprises . in the dissertation , importance of data transmittal and database security are illustrated , the customer requisite analysis and the entire design are elaborated as well 该模型在一定程度上能保证数据在远程存取过程中的安全，同时保证数据在数据库端对非相关人员的不可见性。
So my research emphases on oligarch monopolized market , and give logic deduction on scale economics , degree of concentration , efficiency , behavior and so on . the aim to do this is to find correlative results between all the factors 重点对寡头垄断市场结构进行研究，并对它的规模经济、市场集中、绩效、行为等要素从理论上进行逻辑推导，找出各个要素之间的相关或者非相关的联系。
Based on the international competition , the resources and managerial capabilities of chinese enterprises , it is the right choice for most of our enterprises to choose moderate diversification associating with their core competence , but not unrelated diversification 从目前国际竞争和我国企业现有的资源条件、管理能力来看,不宜追求高度非相关多元化经营,以培育核心竞争力为基础的适度多元化是当前我国绝大多数企业的正确选择。
Port diversification strategy may be divided into related business and unrelated business , among which related business strategy may be further divided into concentric related business and unconcentric related business ; unrelated strategy divided into unified strategy and group strategy 港口多元化经营的战略可划分为相关多元化和非相关多元化，其中相关多元化战略又可分为同心相关和非同心相关，非相关战略可分为联合式和集团化相关战略。
Meanwhile , with economy globalization bringing more intensive competition to corporation , peeling off the non core business and strengthening the core techniques become the corporation ' s crucial ideas , so the modes of logistics self - operating and outsourcing are appearing 同时经济的全球化给企业带来了更强、更激烈的竞争，剥离非核心业务，强化核心技术成为当今企业竞争战略调整的基本思路，企业不仅剥离了非相关产品，而且剥离了产品经营中的非核心业务。
( e ) the essence of strategy of the firm relates to three hierarchies with dominant logic , firm strategy and business strategy ， which represents unification of idea , learning and position as strategy ; the evolutionary theme of the growth of the firm can account for and forecast both positions and development such as specialization , diversification ( related or unrelated ) , vertical integration , strategic alliance and network and business strategic exit 五、企业的战略本质涉及主导逻辑战略、企业战略、业务战略三个层级，是观念、学习和定位作为战略的有机统一；企业发展的演化主题解释和预测了企业的专业化、多元化（相关或非相关） 、垂直整合、战略联盟、虚拟的定位和发展以及业务战略退出。
This text still thinks while realizing the vertical integrative development of coal hcc should pay close attention to the development of the non - relevant industry especially hi - tech industry , permeate in its field through the operation of the capital in order to disperse business risk further , make the foreshadowing of the transition and further development of enterprise 本文还认为，霍煤集团公司在实现煤炭纵向一体发展的同时，应该关注非相关产业特别是高科技产业的发展，并通过资本运作向其领域渗透，以进一步分散经营风险，并为企业的进一步发展和转型做好铺垫。
Computer simulation results show that the proposed algorithm reduces the signal distortion and the reverberation which are caused by misadjustment errors in the adaptive filter and the correlated component of the speech in the reference signal compared with a conventional adaptive noise canceller ( anc ) 仿真结果证明nanc算法有效克服了影响传统自适应噪声抵消系统( anc )性能的一些瓶颈，如两输入中的非相关噪声，参考输入中的信号成分与自适应滤波器失调误差而产生的信号失真、回响等情况。
