control plant造句
例句与造句
- We tested the dreb1c ' s effect on salt tolerance . the result showed that overexpression of dreb1c could improve salt tolerance in arabidopsis . the transgenic plants could develop well in 100 mm nacl and 150 mm nacl whereas control plants grew slowly and was seriously retarded ; in 0 mm nacl , transgenic plant roots are stronger than wild type .
在含100mmnaci的ms培养基上胁迫十天后，野生型植株生长受抑制，较矮小;而转基因植株生长正常;在含150nlmnacl的ms培养基上胁迫十天后，野生型植株生长受严重抑制，叶子卷曲，盐害症状明显，而转基因植株仍能较正常生长;在不含naci的ms培养基上，转基因植株根系发达，尤其侧根数目明显多于对照。 - In contrast to automaton / formal language model , petri net model has advantages such as the capability of handling of concurrence , the graphic representation of controlled plants and the high computation efficiency etc . hence , petri net is taken as a mathematical tool to study the control theory of des here
由于与自动机形式语言相比， petri网在系统状态表示方面所具有的图形化和分布式等优点及其在计算效率方面所拥有的优势，我们采用petri网作为数学工具研究离散事件动态系统监控问题。 - In normal greenhouse condition , coda - transgenic wheat lines ( to ) had the same plant morphorlogy and pollen i2 - ki staining rate as untransformed control plant . after treating with 300 mm of 5 - fc , however , changes in configurations of spikelet , floret and anther have been observed in the transgenic lines but not in the control , and 50 % gus - positive lines displayed outside - opened glume , abnormal stamen , smaller and thinner anther , shorter filament , and failure of selfing . in parts of 5 - fc - treated transgenic lines , the pollen staining rate by i2 - ki was much lower than that of untransformed control
温室栽培的转基因小麦苗( t _ 0 )未喷5 - fc处理时植株外部形态和花粉碘-碘化钾染色的着色率与未转基因的对照没有差异；用300mm的5 - fc处理后，发现有50 gus阳性株系与对照有明显的区别，表现为小穗颖壳外张，花丝短缩，花药发育不良，较小、黄白色且花粉粒少，自花不授粉，无外来花粉授粉则不结实。 - In the positioning servo - system , which generally is configured by the d . c . pulse width modulator ( pwm ) velocity governing system and position servo - loop , the parameter perturbance of pwm velocity loop really exist by reason of such as the load behavior ; power voltage supply ; operating setting value , etc . 1 , 2 ， and it cannot be ignored . by using the identification technique to form the mathematical model of the system , authors have confirmed the facts . therefore , to design the discrete sliding mode controller ( dsmc ) of the positioning servo - system , the perturbed parameters value bounds of the pwm velocity loop , which is as the controlled plant of position servo - loop , should be accounted . consequently , the design principle of dsmc for accounting system with parameter perturbance is proposed by the authors . the proposed method can ensure the stability of system with parameter perturbance and the behavior of non - overshoot , fast precise positioning . in order to reveal the effects of the design method , the comparative research work is done by the authors . also , it has been tested in an industrial experiment , the results proved it is satisfactory
由直流脉宽调速系统( pwm )和位置环构成的定位系统中，速度环的参数随负载特性；电网电压；给定工况而摄动是不容忽视的.作者通过系统辨识建模也证实了这一事实1 , 2 .因此在设计位置环的离散滑模控制时，必须针对速度环(即位置环的控制对象)的参数摄动范围采用“对象参数摄动离散滑模控制器的设计方法” ，以确保系统在参数摄动时的稳定性和快速、无超调、准确定位的优良动态品质.为剖析该设计方法的控制效果，本文作了对比性研究，并将该设计方法用于工业试验中，取得了满意的结果 - Due to the fact that fuzzy control , compared to conventional controls , is more suitable for those controlled plants that are difficult to model analytically and exhibit coupling features as well as nonlinear characteristics , the fuzzy logic methodology is employed to solve the modeling and optimizing control problems of water supply system
由于模糊控制比传统控制方法更适用于那些难以建立解析模型、具有强耦合和非线性特性的受控对象等方面的优点，本论文采用模糊逻辑方法来解决供水系统的建模和优化控制问题。 - It's difficult to find control plant in a sentence. 用control plant造句挺难的
