查询词典 high frequency

For intramolecular electron transfer reactions in solution,the fluctuations of the intramolecular vibrational modes are much faster than that of solvent mode.Thus,the reaction-diffusion equation is commonly used to describe the motion of solvent,with a sink function to treat the vibrational high-frequency mode.Based on this theory-so -called the Sumi-Marcus theory,we proposed an imaginary-time split operator approach to solve the reaction-diffusion equation.The approach is applied to evaluate the intermolecular ET rate between oxazine 1 and N,N-dimethlaniline.By measuring the two average survival times of the donor state probability and the rate constant in long time limit,the full kinetics of the ET is revealed with a variety of sink functions.

对于扩散控制的溶液中的电子转移反应，分子内振动模的运动比溶剂运动快很多，Sumi-Marcus理论提出用反应扩散方程(reaction-diffusion equation)处理溶剂的扩散运动，而分子内的振动用sink函数来表示，我们基于此理论发展了用虚时间分裂算符的方法(imaginary-time Split operator approach)解反应扩散方程，并将其应用于嗪1(oxazine 1，OX1)和N，N-二甲基苯胺分子之间的电子转移反应，Sink函数采用几种不同的微扰表达式，通过计算得到给体几率衰减的两种平均速率和长时间极限下的速率常数，揭示了该体系电子转移过程中的一些动力学性质。

For the first time, this study conducted a series of field sampling in multiple locations over several years and demonstrated that the B and Q biotypes first invade areas with high frequency of transport through human movement of plant materials, and then rapidly spread into surrounding areas and displace indigenous genotypes, and in parallel with displacement significant changes in sex ratio occurred in the mixed populations. Crossing experiments demonstrated that in the B. tabaci species complex there are many genetic groups that are completely or nearly completely isolated in reproduction. Apart from behavioural mechanisms, difference in host plant suitability and insecticide susceptibility between whitefly biotypes may also play important roles in the displacement of indigenous whiteflies by alien whiteflies in Zhejiang.

本研究首次以一个地理区域内广泛系统的野外调查数据证实，B型和Q型烟粉虱首先通过花卉苗木调运入侵交通较为发达的地区，然后迅速向周边扩张并取代土著烟粉虱，同时入侵取代过程伴随着混合种群中性比的变化；杂交试验证明烟粉虱复合种内存在多个生殖上隔离或基本隔离的遗传群；B型烟粉虱在浙江省内迅速取代土著烟粉虱，除行为机制外，生物型之间寄主适应性和药剂敏感性等方面的差异也可能在此过程中起着重要作用。

"Our findings document an abnormality of the neuroregulation of high-frequency heart rate variability, most likely indicative of parasympathetic nervous system activity, in members of a Naval Reserve construction battalion who became chronically ill during or shortly after service in the 1991 Gulf War," the authors write."Our findings, although unable to attribute specific symptoms of Gulf War veterans directly to early autonomic dysfunction, suggest possible links to be explored in future research."

研究人员指出，海军后备建筑大队的成员，在1991年波湾战争时或是结束后立即患病的成员中，我们的发现记载了高频心跳变异神经调控的异常，最可能代表副交感神经系统；我们的发现，虽然不足以将湾岸症候群特定的症状直接与早期自主神经失调相连，但是暗示这可能在之后的研究中进一步被厘清。
