A new mathematical model is put forward numerically to simulate the wheel ovalization.. In the numerical simulation, the dynamic model of a half railway vehicle coupled with a tangent track is employed. Using the new numerical method investigates vehicle-track coupling system dynamic responses including lateral and vertical displacement of wheelsets and the vehicle, lateral and vertical vibration acceleration of the track at different phase angle of the two side wheels of the same wheelset, which are compared with that of the traditional model. The numerical results show that the discipline and frequency of dynamic responses are accordant, amplitude and phase of lateral dynamic responses are different. It is concluded the traditional track geometric irregularity excitation model does not simulate the effect of periodic wheels ovalization on vehicle-track coupling system dynamic behavior truly, the new model is more accurate and reasonable.
本文研究了车轮二阶周期性非圆化—椭圆化,建立了一个新的模拟车轮椭圆化的数学模型,结合车辆-轨道空间耦合动力学模型,计算了同一轮对左右车轮不同相位和车轮椭圆度下轮对和车体的横、垂向位移,钢轨横、垂向振动加速度,并与传统模型计算结果作了对比,分析表明两种模型的动力响应变化规律和频率一致,但横向动力响应幅值和相位均存在不同程度不可忽略的差异,因此传统的轨道几何不平顺激励模型不能真实模拟车轮的周期性椭圆化对车辆-轨道耦合动态行为的影响,而本文模型更能反映实际椭圆车轮与钢轨接触情形,计算方法准确而合理。

This study demonstrates optically and spatially band-tunable color cone lasers based on DDCLC cells with a photoisomerizable chiral dopant. The band-tunability is attributable to the recovery of the helix of the CLC resulted from the trans-cis isomerization induced decrease of the helical twisting power of the chiral dopant.The more the chiral cis-isomers are produced, the larger the tuned lasing band is.
本文主要藉由在胆固醇液晶射中加入可光致同素构化亲手性材,使胆固醇液晶所输出的彩色锥角射波段可光调控及空间调控,其射输出波段可调控的机制是由於当同素构化反应产生后,光致同素构化亲手性材的HTP值低并造成胆固醇液晶距改变,藉此间接调控输出的射波长,同素构化的程愈高,胆固醇液晶所输出的彩色锥角射波段可调控范围也愈大。

At a certain range, habitat loss and its spatial structure can benefit the control of the epidemic disease, which indicates the possibility of using human disturbance in habitat as a potential epidemic-control method in conservation.(6) Not only the quantity of habitat loss but also the spatial correlations of patch types caused by nonrandom habitat loss affect the invasion and transmission of disease. More fragmented landscape (high amount of habitat loss, low clustering of lost patches) hinders the parasitic infection, which also indicates that whether the spatial heterogeneity benefits or hinders the invasion is dependent on the considered ecological process.(7) Two components of the spatial heterogeneity (the amount and spatial autocorrelation of the lost habitat) form a trade-off in determining the host-parasite dynamics.(8) Within a certain range of habitat loss, host can counterbalance the positive and negative effects, and shows a rising tendency.(9) The epidemic is more likely to break out in the prey-predator system if only a small amount of habitat loss.(10) A highly aggregated distribution of species is a common behavioral strategy when dealing with habitat loss or other environmental stresses.(11) The parasite-host/prey-predator eco-epidemiological systems have the similar mechanism with the intraguild predation systems, and the predator acts as the intraguild predation, the infected prey acts as intraguild prey, and the susceptible prey acts as shared resource.(12) Species at the highest trophic level are no longer affected the most by habitat loss, which depend not only on the biological mechanism but also on the external environmental disturbances.
随着邻体数目的增加,病毒的感染力度变得更大而且在空间上形成聚集的波形;(5)生境破坏及其空间结构在一定范围内有利于疾病的控制,这暗示人为对生境的干扰可作为疾病控制的一个潜在方法;(6)生境破坏的数量以及不同类型生境的空间分布格局都显著地影响了寄生病毒的入侵和传播,生境破碎化程度越高(高丧失斑块的数量或低聚集程度),将越有害于病毒的入侵和传播,这暗示了空间异质性是否有益于物种的入侵依赖于所考虑的生态过程;(7)由生境破坏引起的空间异质性的两个组分之间存在负偶联关系trade-off(8在适度的生境破坏范围内,宿主种群能够平衡生境破坏带来的正负两种效应并呈现增长趋势;(9)在捕食-食饵系统中,寄生感染病毒极有可能在生境破坏量较低时爆发;(10)物种在面临生境破坏或者其它环境压力时表现出更高的聚集分布策略;(11)寄生-宿主/食饵-捕食生态传染病系统与共位捕食食物网结构具有相似的生物机制,其中捕食者扮演共位捕食者的角色,已感染食饵作为共位食饵,易感染食饵扮作共同消耗的资源;(12)位于最高营养级水平的种群对生境破坏的响应不一定是最敏感的,这不仅依赖于内在的生物机制同时也依赖于外在的环境干扰。

The article presents the developing condition of PWM and SVPWM first.Then the theory of SVPWM is discussed in detail.The SVPWM is based on the thought of magnetic chain tracking.It makes the ideal magnetic chain circle of three-phased sysmmetry electric motor supplied by three-phased sysmmetry sine wave voltage for basis,uses the practical magnetic chain vector formed by the different switch modes of three-phased inverter to track the basic magnetic chain circle.During the course of tracking,the inverter changes the switch modes properly to form the PWM waves.Then the modulation wave of SVPWM is analyzed in detail.The modulation wave of SVPWM is implicit,but the analogous modulation wave in A-B-C axis needs to be calculated in order to expose the internal relation of SVPWM and SPWM.That is to show the implicit modulation wave of SVPWM. SVPWM actually is a transformed SPWM ruly sampled by the modulation wave which is injected by the zero prefaces based on space vectors.
本文首先对脉宽调制技术的发展现状进行了综述,在此基础上分析了电压空间矢量脉宽调制技术的发展现状;接着对空间电压矢量脉宽调制技术的基本原理进行了详细的分析和推导,SVPWM是基于磁链追踪的思想,它以三相对称正弦波电压供电下三相对称电动机定子理想磁链圆为基准,由三相逆变器不同开关模式下所形成的实际磁链矢量来追踪基准磁链圆的,在追踪的过程中,逆变器的开关模式作适当的切换,从而形成PWM波;然后详细分析了电压空间矢量脉宽调制技术的调制波,虽然SVPWM法的调制波是隐含的,但是为了揭示SVPWM法与SPWM法的内在联系,需要求出SVPWM在A-B-C坐标系上的等效调制波,也就是将SVPWM的隐含调制波显化;SVPWM实质是一种基于空间矢量在三相正弦波中注入了零序分量的调制波进行规则采样的一种变形SPWM。
