Continuous dynamics may be considered as the continuous variables while the discrete ones may be considered as versatile incidents , such as sampled - data , logic switching , transformation of system structure and shift of balance point , et , al 其中连续变量往往对应于实际系统中的连续动态，而离散变量则多种多样，既可能是数据采样，也可能是逻辑切换、系统结构的变化、平衡点的转移等等。
This paper will apply the theory of the model reference self - adaptive control system design based on the theorem of balance point stabilization in the velocity system of asymmetric cylinder controlled by symmetric valve , to make the system ’ s output to trace the reference model ’ s output 本文将基于平衡点稳定定理的模型参考自适应控制理论应用于阀控非对称缸速度系统中。使被控系统输出渐近一致的跟踪参考模型的理想输出。
Fourthly , calculation and analysis on electricity price enduring ability and target market price shows that : market price should be within consumer ' s ability . then find out the balance point between supplier side price and consumer side price 第四、在对高能耗企业用电的电价承受能力和供电方目标市场定价进行测算和分析的基础上，得出供电方对目标市场的定价必须在用电方能承受的电价之内，从而，找到供用电双方电价的平衡点。
The essence ofmotion accompanies the functionand simplified design is perfectly embodied in this product ; the soft main lines of the porcelain - white bulb just look like a bulb when viewed from far , while it is a sedulous design to obtain the balancing point when observed from near 形随功能简约设计的精髓在该产品中完美体现;瓷白色灯泡柔和的主线透过高清玻璃,远处乍看仿佛只是一个灯泡,细看则是经过设计师精心寻求平衡点的刻意设计

It is the optimal portfolio investment that meets the investor , and this portfolio realizes some balance between the maximal of the expected return and the minimal of the incertitude of the return variance ( risk ) . and of course this balance point is a best point which meet the investor most 通过以上求解，得到满足投资者偏好的最优证券投资组合，这个组合实现了在预期收益最大化和收益率不确定性(风险)的最小化之间的某种平衡，而这个平衡点就是投资者所需要的，最符合其投资要求的一种方案。
At present , china is undergoing an economic transformation , the gradual establishment of the rule of law , the rapid expansion of the capital market , various forces trying to find the balance point . but the existing legal system of the securities supervision has serious deficiencies , so it ’ s not fit to the further development of china ’ s securities market 目前,中国正处于一个经济体制转轨、法制逐步完善、资本市场急剧扩大、各种对比力量努力寻找着平衡点的时期,现有的证券监管法律制度模式存在着严重的缺陷,不适应中国证券市场的进一步健康发展。
Under this situation , i think the role of the government is not as simple as what our secretary for justice says , that the administration just needs to make clear where the government stands . what the government should do is to listen carefully to the different voices in society , and to explain and reconcile the differences , so as to achieve harmony in our community . in particular , this ordinance emphasizes the existence of a balance point , and it is difficult to identify what is absolutely right , and what is absolutely wrong 在这情况下，我觉得政府的角色似乎未必如局长所说，只是阐明政府立场那么简单，而是应该细心聆听社会上很多不同的意见，尽量作出讲解和协调，务求最后能令社会有心平气和的气氛，特别是这项法例本身著重要有一个平衡点，根本不能说哪个绝对是对，或哪个绝对是错。
For these reasons , we can apply the theory of the model reference self - adaptive control syetem design based on the theorem of balance point stabilization in the force system of asymmetric cylinder controlled by symmetric valve . the main idea of model reference self - adaptive controller is to make the self - adaptive control error incline to zero as time passed . the task to design adaptive controller is to find the control input that can make the output of the controlled system to follow that of the reference model 因此将基于平衡点稳定定理的模型参考自适应控制系统设计理论应用于阀控非对称缸力系统中,其基本原理是使自适应控制误差随时间的推移而趋向于零,自适应控制器设计的目的是寻找使被控系统的输出渐近一致的跟随参考模型的输出的控制输入,以此来改善被控系统的性能。
