The man-machine interaction is very convenient and fast, and it has function of self-adapting and self-diagnosing. It provides the solid basis to prepare the new invertor of intelligence, digit, information and adapting the industrial field bus technology

同时，具有自适应、自诊断功能，为新一代智能化、数字化、信息化的电—气转换器、定位器的研制以及适应工业现场总线技术打下良好的基础。

Positioner is used to control or throttle flow by modulating the air to the actuator in response to an external 4-20 milliamp control signal input which is converted to a proportional 3-15 psi pneumatic signal used by the positioner.

当外部4~20毫安控制信号输入转换成线性3~15 psi气动信号输入被采用后，定位器通过调节执行器气源流量来实现控制和调节阀门流量。

The Transmitter is an internally mounted module for use in the Positioner.

这种发射器是用在定位器内的内部安装模块。

Contract:This article disausses the principal of main steam temperature control system according the problems in running,including the unreasonable main steam pressure set point volue,hot air injection flow is not acciurate,Charge of steam temperature has the big delay and the common PID can′t satisfy the regulate′s demandthen take the according measures,adopt smith predictor,change to ABB intelligent positioner,add the hot air injection antiblock device,test the main steam temperature automation and optimization the specificator.

中国国电集团公司菏泽发电厂热工，山东摘要：本文论述汽温控制系统组成原理，针对运行中发现的问题，包括一次风母管压力自动设定值设计不合理，导致主汽温度和再热汽温度变化幅度加大，底部注入风量和汽温参数测量不准确，汽温变化迟延大，常规PID满足不了调节要求，采取了相应措施，改用史密斯预测器，更换为ABB定位器，增加底部注入风量等测点防堵装置，并对主汽温自动进行试验和参数优化。

High mechanical-electrical transformability and excellent controllability set ferroelectrics in the center-stage of functional materials.

铁电陶瓷已经被广泛应于致动器，微定位器等机敏器件。随着铁电陶瓷日益广泛的应用，其可靠性问题变得尤为突出与重要。

Pneumatic control valve of the film room, while not consume air, but if the gas supply system with water, oil and other impurities, then the valve positioner will, following such attachment plug and actuator failure.

气动调节阀的膜室虽然不消耗空气，但如果气源系统含有水分、油污等杂质，则会使阀门定位器、继动器等附件堵塞并发生故障。

The output of compilers,assemblers, linkers, and locator s are files containing object code.

编译器、汇编器、连接器和定位器的输出文件都含有目标代码。

The output of compilers,assemble rs, linkers, and locators are files containing object code.

编译器、汇编器、连接器和定位器的输出文件都含有目标代码。

The other 2 locators are positioned on the ground at approximately the start and end of where the shadow falls.

其它两个定位器是定位在地面上，大约在落下阴影的开始和结束的位置。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
