循环

An engine cyclic variation model has been built by using the residual gas temperature for the n-th cycle as the input of the model, through constant pressure intake process, adiabatic compression process, constant volume combustion process, adiabatic expansion process, adiabatic blow down process and constant pressure exhaust process to approximate the thermodynamic processes in the cylinder, finally the residual gas temperature for the (n+1)-th cycle can be estimated.

基于循环间变动的排气温度建立了一个发动机循环变动模型。在这个模型中，第n个循环的排气温度作为模型的输入，通过定压进气过程、绝热压缩过程、定容燃烧过程、绝热膨胀过程、定容放热过程和定压排气过程来近似汽缸内的热力学过程，最后得出第n+1个循环的排气温度。

The problem is that to represent a pretested loop the assembly language code must contain two jump instructions: a conditional branch instruction in the beginning (that will terminate the loop when the condition is no longer satisfied) and an unconditional jump at the end that jumps back to the beginning of the loop.

因为 为了实现预测试循环汇编语言中必须包含两个跳转指令：一个条件跳转指令用以跳转到循环开始的位置(该条件指令也起着条件不被满足时中止循环的作用)；另一个是结尾处的一个无条件转移指令以便跳转回循环起始处。

This paper focuses on the node stability of eco\|industrial symbiosis system from the view of environmental economics, and set up the Node Symbiotic Economics Model on the enterprises of eco\|industrial symbiosis system by analyzing relationship on the pollutants recycle of the inter\|node interconnected enterprises. Through the observation of the supply change in the enterprise′s recycling contaminants at the node based on the mathematical solutions to the model, the effects of outside disturbances on the balance of supply and demand has been studied. If the elasticity of the product price is equal to or less than 1, the node can achieve conditional stability and if the elasticity of the product price is more than 1, the node will fluctuate periodically around a stable point, and even chaos can appear.

Based on the second-order statistics, cyclic autocorrelation function , a method of demodulation is deduced.

推导了二阶循环统计量——循环自相关函数的解调方法，该方法通过搜索循环频率而将调制源分离在循环域的低频段，并且调幅和调频信号有不同的解调结果。

The methods of the first-and second-order cyclic statistics-based hybrid and the first-and third-order cyclic statistics-based hybrid have been proposed. Using the first order cyclic statistics, the frequencies of harmonics corresponding to nonzero mean multiplicative noise were obtained. Then the mean of multiplicative noise can be estimated. With this, harmonics can be retrieved by second or third order cyclic statistics.

提出了基于一阶、二阶循环统计量的混合方法和基于一阶、三阶循环统计量的混合方法，即先利用一阶循环统计量得到对应非零均值乘性噪声的谐波频率，再求出与谐波频率对应的乘性噪声均值，去均值后用二阶或三阶循环统计量来恢复谐波。

The invention now is concerned with the problem of creating a control device of the kind specified above, intended for bending-machines, by which more frequently needed types of loop may be produced considerably more rationally than was hitherto possible, and a device according to the invention achieves this by means of a loop-type preselector for selecting at will a required one of a number of fixed basic programs, each being associated a different type of loop, and which determines the sense of direction and amount of the successive angles of bend necessary in that loop-type, and a length-of-side selector for selecting the lengths of successive sides of the loop of the type selected.

现在的议题是创造一个上面指定的一种控制装置的问题表示关注的发明，弯曲机，旨在其中更经常需要类型的循环可能产生相当多的理性可能比迄今为止，和设备按照发明达到了一个循环的方式，类型选择在预选这将是一个固定的基本程序的数量，互为关联的不同类型的循环，需要之一，并确定了方向和角度的连续弯金额意识有必要在该循环型，以及根据不同长度选择了该类型的循环连续的边长方选择选择。

The article is passed " circular economy promotes a doctrine " the requirement to jurisprudence of circular economic policy, in code of economic policy of Heibei province loop system, government is in mechanism of the function in circular economy, market was promoting the respect such as the deploys resource effectively action in circular economy and social responsibility to offer countermeasure and proposal.

本文通过《循环经济促进法》对循环经济政策法律体系的要求，在河北省循环经济政策法规体系、政府在循环经济中的职能、市场机制在促进循环经济中有效配置资源的功能以及社会责任等方面提出了策略和建议。

The article altogether divides into five parts, separately expositions the circular economy basic concept, the tax policy in the development circular economy function mechanism, the overseas development circular economy tax policy aspect model and the inspiration, our country develops the circular economy taxes and fees policy analysis as well as our country develops the circular economy tax policy suggestion.

文章共分为五个部分，分别论述了循环经济的基本概念，税收政策在发展循环经济中的作用机制，国外发展循环经济的税收政策方面的借鉴与启迪，我国发展循环经济的税费政策分析以及我国发展循环经济的税收政策建议。

Firstly, according to the relationship between classic Carnot cycle and Lorenz cycle, the paper evaluates the cycle characteristics and thermodynamic properties of NARMS (Non-azeotropic mixtures), and compares the energy-saving difference between pure and mixed refrigerants. The main of factors that affect heat pump operating efficiency are analyzed in theory and using the Second Law of Thermodynamics the exergy are evaluated in components of heat pump system, in the end a conclusion is drew that all of the exergy have bearing on working fluids' properties.

本文首先从经典的Carnot逆循环与Lorenz逆循环相对关系出发，评估了非共沸混合工质循环的特点以及热力学性质；在不同环境条件下，比较了单工质与混合工质的循环特性差异；针对非共沸混合工质热泵循环效率的主要影响因素（即工质本身的热物性和系统部件特性）进行了理论分析，并利用热力学第二定律对热泵系统的各个主要部件进行了可用能分析，最终发现每一处可用能损失均与工质物性有关；在此基础上提出了减少可用能损失的方法—寻找适宜的非共沸混合工质。
