And then , this parallel connection operating optimization reconstruction project is put forward in variable speed pump of circulating water system , finally we found the optimization mathematic model and workout its optimization operation program 然后又结合某电厂循环水系统优化运行方式的改造，给出循环水系统变速泵并联运行优化改造方案。通过建立变速泵并联运行时的优化数学模型，并编制了相应的优化运行程序。
Then this scheme is materialized by an integrated program named control of the parallel connection of arc - extinction coils , which can receive the data from rtu and send the control commends through the special database that is connected with ems of distribution network 然后利用一套完整的消弧线圈并联运行控制程序把上述方案体现出来。此控制程序通过专用数据库与配电网ems系统接口，进行接受数据和下达控制命令。
The adaptive sr , studied in this thesis , means that the system automatically selecting parameter with a recursive algorithm , not adaptively adding noise . a parallel connection sr system is introduced and its application in digital frequency shift modulation signal transmission is discussed 我们初步提出了参数自适应随机共振的思想以及收敛算法，同时，我们还研究了数字信号载波调制传输中的并联随机共振系统。
Impedance includes resistance and capacity reactance , and this capacity and resistance are parallel connection , the simultaneous reduction of the capacity reactance and resistance will make a . c . impedance reduce more acutely , therefore the sensitivity measured by this way is improved much more 同时交流阻抗包括电阻和容抗，且电阻和电容是并联的，电阻和容抗同时减小必将使交流阻抗减小更多，所以用该方法测试的灵敏度得到了明显提高。
In the circuit , using the way of step - by - step magnify , a normal sine wave signal through former circuit export for the next circuit , and this signal that have been magnified push the next step . the main magnify circuit use the method of high power dynatron that is parallel connection 在回路中采用逐级放大的方法，将一个标准的正弦波信号通过前级放大，输出给后级，推动后级放大回路，主要的功率放大回路中采用大功率三极管并联实现功率放大输出。
The whole high power switch supply have four bidirectional dc / dc converters which are parallel connection . the theory of phase - shifted full - bridge zvs pwm dc / dc converter and the theory of push - pull boost converter are introduced . the methods of realize zvs ( zero voltage switching ) is studied in detail 文中介绍了移相全桥式软开关变换及推挽式dc dcboost变换的工作原理，分析了移相全桥zvs的实现和占空比的丢失，并设计了各自的控制电路和保护电路。
Multiplexed sensor technology was studied , a new way was applied to realized series connection and parallel connection multiplex . 5 . new generation fiber optic strain - sensing gauge was applied to realize long period strain healthy monitoring of dafosi bridge in the yangtze river 在传感系统复用技术研究方面，本文比较了几种法珀传感器的复用方式，考虑测量系统的难易程度和成本，选择了空分复用方式作为传感系统的复用方案，提出了腔长域解复用的新方法，并进行了串并联复用仿真。
So the conductive behavior in ac field was equivalent with the parallel connection of a resistor and a capacitor , the nonlinearity of v - i characteristics originate from a combination of the implication of the nonlinear contribution of tunnel conduction between graphite particles and the production of additional conducting pathways under sufficiently strong local fields , which is the function of the gap between graphite particles and has a relation with the transition ability of electrons 导电沥青混凝土的导电行为则可用隧道效应进行分析，交变电场中的导电行为可等效为电阻r和电容c并联，非线性v - i特性产生于隧道效应时粒子间的非线性导电和高电场时诱发额外的导电通路，二者是粒子间隙的函数，与电子跃迁能力有关。
The simulation model for water resources system based on macro - scale dual water supply is established herein by taking the large water resources system of multi - water - source ; multi - consumer ; multi - step series - parallel connection as the study object , so as to provide the technical support for realization of the rational allocation of water resources 摘要以具有多水源、多用户、多级串并联的大型水资源系统为研究对象，建立基于宏观尺度分质供水的水资源系统模拟模型，为实现水资源合理配置提供技术支持。
