Additionally , a special force / torque sensor was designed for the friction measurement of a rotational traveling wave ultrasonic motor . the elastic body of two - component sensor was optimized with finite element method . one dimension of the sensor measures normal force , another measures torque 针对试验的特殊要求,并利用有限元法对传感器进行了结构优化,设计了组合式两维传感器,该传感器的一维测量法向正压力,另一维测量扭矩。
Quorum - sensing systems can be divided into two paradigmatic classes : luxi / luxr - type quorum - sensing systems in gram - negative bacteria which produce acyl - homoserine lactone ( ahl ) autoinducers , and oligopeptide / two - component - type quorum - sensing ciruits in gram - positive bacteria which produce autoinducing peptide ( aip ) autoinducers . in contrast to the two paradigmatic quorum - sensing systems , vibrio harveyi produces and responds to an ahl - type autoinducer termed ai - 1 and a novel signal molecule named ai - 2 Qs系统可分为两种典型的类型,即革兰氏阴性细菌的luxi luxr型qs系统,革兰氏阳性细菌的寡肽双组分型qs系统,分别以酰基高丝氨酸内酯( acyl - homoserinelactones , ahl ) 、寡肽( autoinducingpeptide , aip )为信号分子。
In two - component model of hydrogen - bonded chains , the system with nonlinear and linear coupling between proton sublattice and heavy - ion sublattice is investigated . fast - mode soliton pair and slow - mode soliton pair are obtained . as for fast - mode soliton the effective mass of the kink in the proton sublattice decreases due to the nonlinear coupling and increases due to the linear coupling . for slow - mode soliton , the thing is quite opposite to that of fast - mode soliton 在氢键链二分量模型中,研究质子子晶格和重离子子晶格相互作用项中同时含有非线性耦合和线性耦合两部分的系统,得到快模孤子偶和慢模孤子偶.对于慢模孤子而言,非线性耦合降低了质子子晶格中孤子的有效质量,而线性耦合增加了质子子晶格中孤子的有效质量;对于快模孤子而言,情况正好相反
On the basis of the two - component soliton model , discussed the motion of a kink soliton in the presence of an external force and damping in hydrogen bonded systems , investigated the influence of motion and the optical model of the heavy - ions sublattice on the proton sublattice . the solution , the mobility and the conductivity of a kink soliton are found . the calculated results are in good agreement with the experiment results 采用二分量弧子模型,讨论了在外场和阻尼存在的情况下,氢键系统中扭结弧子的运动,研究了重离子子晶格运动和光学模对质子子晶格的影响,获得了扭结弧子解、迁移率和电导率,计算结果和实验值相一致
At stage 3 , the four - component construct was confirmed the best compared with the one - component , two - component and three - component model by the analysis of another 346 subjects using confirmatory factor analysis ( i . e . cfa ) . in addition , the results also indicated the organizational justice questionnaire had high reliability and validity 第三阶段,重新取样,通过对来自4家企业346名被试的数据进行验证性因素分析,结果表明与单因素、二因素和三因素结构的模型相比,四因素模型对数据的各项拟合指标最好。
