提出要求

However, transmission rate and bit error rate are fixed in some communication systems.

实际的通信系统一般要求传输速率和误码率一定，提出的算法就以最小化发射功率为目标，在发射端自适应根据MIM0系统各个空间子信道的增益来分配传输比特、发射功率，最终获得好的频谱效率，并在满足通信系统要求的前提下，降低发射功率。

Specifically for the characteristic of application, the main body of this book is discuss the fore-end arrange specification and signal chain circuit specification of city and town public, put suggestion on the design of the system, reach the consistent between needs of applications and the design of technology, so that the system can bring maximal efficiency into play.

本文针对这一应用特点，对城镇广场的前端布置技术要求、信号链路技术要求展开讨论，对系统设计提出建议，力求应用需求和技术设计一致，发挥系统最大的效率。我的译文如下，帮忙改下，谢谢了。

Without disputing Gray's exegesis part of the argument, I'd like to take issues with some of his defensive points on behalf of the historicist Berlin in asserting that liberal institutions can have no universal authority, and that liberalism can be best conceived as a particular form of life, with no universal claim on reason, foundation in human nature or privileged place in history.

本文并不争论格林理论中的诠释部分，我只是想讨论格林站在历史主义者伯林的立场上所辩护的下述观点：自由主义的机制并没有普世性的权威，而自由主义至多只是一种特殊的生活方式，不能对理性提出普遍要求，也并非在人性中有其普遍基础，不能在历史中要求特殊的地位。

From the view of torque controlling strategy, the relation between the torque controlling strategy such as the electric current feedback method、 PWM open loop method etc and the vehicle driving way is analyzed firstly, then the conclusion could be drawn that the PWM open loop method has more advantages than the electric current feedback method when they are both used in the same vehicle which is direct driving by hubcap motor. Secondly, based on the electric motor mathematic model and its experiment, a new permanent brushless dc motor phase electric current detector method in which a digital signal processor and single current sensor are used is introduced.

从转矩控制策略角度来看，分析了电流反馈法以及开环PWM电压调速控制方法与车辆的驱动方式关系，得出了电机驱动电压受限的情况下，无论是从对车辆的动力性能影响还是从对车辆的驱动要求来讲，开环PWM电压调速控制方法较电流反馈法更适用于以轮毂电机直接驱动方式的两轮电动车中；其次，根据电机的数学模型以及电机试验波形，提出了一种利用数字信号处理器以及单个电流传感器检测三相永磁无刷电机电枢电流的新方法，这种方法具有较强的适应性、实时性，它可以根据控制系统的要求，适时地提供所需电流数据，是目前许多文章关于无刷电机相电流平波的重要技术基础。

So even higher request is put forward to security and economy of electric power production, moreover operators are requested imminently to have better management of technology and operation and ability to response the emergency.

这样对电力生产的安全性和经济性提出了更高的要求，并迫切要求机组运行人员具有较高的技术、操作水平和应变能力。

High level QoS request operation can rob the channel resource of low level QoS request one in order to ensure the system's QoS performance. The paper gives a rob method towards real time operation and unreal time operation, in additional analysis system's change after robbing. Rob can't run immoderately.

高等级QoS要求的业务可以抢占低等级QoS要求业务的信道资源，以保证其QoS性能，以实时类业务和非实时类业务为讨论对象提出了抢占的方法，对于抢占之后的系统变化进行了分析。

The impresario if class's and grade's pedagogues, the organizer and the shepherd, shows loving concern the student is the essential requirements which proposed to the teacher in charge, raises new person's objective request, is communicates the teacher in charge and the student mind bridge, is to the student universal love mood need.

班主任是班级的教育者、组织者和指导者，关爱学生是对班主任提出的基本要求，是培养新人的客观要求，是沟通班主任与学生心灵的桥梁，是对学生博爱情怀的需要。

With the popularization of Internet technology and the increasing demand of enterprise information construction, enterprises become more and more eager to realize the incompact coupling integration and interoperation among heterogeneous systems of multi-platform and multi-language under the background of Internet, which puts a new challenge to traditional EAI solution.

随着Internet技术的迅速普及和企业信息化要求的提高，企业迫切需要能够方便地在Internet环境下实现跨平台、语言独立、松散耦合的异构应用系统的交互和集成，这对传统企业应用集成解决方案提出了新的要求。

The bank supports a proposal to send standard derivatives contracts through an industrywide clearinghouse that can be monitored by regulators. J.P. Morgan, however, opposes a requirement that the trades should be moved onto an exchange, in part, because it would inhibit the use of customized derivatives that clients require.

政府提出，针对整个行业设置受监管机构监控的票据交换所，通过这类票据交换所发送标准的衍生产品合约，摩根大通对此表示支持，但反对将衍生品交易转到交易所进行的要求，部分原因在于这种做法将会限制客户要求的定制衍生产品的应用。

E. , large volume of instantaneous flow and fast speed of switch with continuous regulation and lower cost.

针对快压射压射控制的特殊要求，提出一种开关阀和电液比例阀并联的混合式快压射速度控制阀结构，理论证明它可以满足快压射速度控制中瞬时流量大，开关速度快，而且能够连续可调、成本低廉的要求。
