这次试招场地位于富士山脚下的富士赛道，在享有盛名的F1与GT擂台对上新一代LS，不明究里的朋友可能以为小编这次吃错了药就是打错了针，开始胡言乱语……会选择在这儿办试驾有三个意义，第一是这次LS的诉求与过去不同，第二是厂家对新LS有高度自信，第三是顺带让我们体验传统日本文化。但厂家解释的越多，我脑袋里的问号也跟着·陕速增加，这款车若提升驾驭乐趣的层次，代表其用户的自驾比例会拉高，增加与GS的产品重叠性之外，跟现行LS的用户群体也不尽相同，感觉有点雾里看花？厂家表示：这次年轻化的新LS希望能吸引新的消费者。

A 2D elastodynamic boundary element method (BEM) is used to solve multiple scattering of elastic waves. The method is based on the integral representation of an elastic wave-field by assuming a fictitious source distribution on the scattering objects or inclusions, i.e. a mathematical description of huygens’ principle, and the fictitious source distribution can be found by matching appropriate boundary conditions at the boundary of the inclusions. Numerical studies show that in the presence of cracks, spatial and scale-length distributions are important and different spatial arrangements of the same scatters lead to profound differences in scattering characteristics, in particular the frequency contents of the transmitted wave-fields. The frequency characteristics, such as the frequency of peak attenuation , can be related to spatial size parameters of the model.

The accuracy of the simulation model has a pro-found impact on the optimal operation of the energy hubs(ehs).however,in many articles,the constant model of the efficiency of equipment is adopted to formulate the operation system,which would probably lead to a simplification of the simulation ***,ehs are typically operated under off-design condition due to the fluctuations in cooling,heating,electricity ***-over,even though the off-design characteristics are considered,few studies have suggested comparing the differences between those two models by considering the operation *** order to assess the effect of the off-design characteristics of eh on the optimal operation accuracy in this paper,two test cases are performed on the fixed and variable load conditions,*** addition,the individual effect of off-design characteristics of each equipment on the optimal operation cost of the eh is also investigated through four optimization *** is worth mentioning that the optimal operation problem of the eh considering the off-design characteristics and on-off status of the equipment is a mixed integer non-linear programming problem(MINLP).By testing the design and off-design models on the two cases,the results of simulation demonstrate that the optimal operation cost for the off-design model is larger than that for the design ***,in the aspect of the authenticity of the system operation strategy,the off-design model performs better than the design ***,a larger relative error of the system operation cost between the two models can be observed when the eh is operated under a relatively lower load condition,revealing that the influence of off-design characteristic on the optimal operation of ehs is too significant to be neglected.

In this work, the effects of quantum confinement on the ground state energy of a correlated electron-hole pair in a spherical and in a disc-like quantum dot have been investigated as a function of quantum dot size. Under parabolic confinement potential and within effective mass approximation Ritz＇s variational method is applied to hylleraas-like trial wavefunction. An efficient method for reducing the main effort of the calculation of terms like τekh exp （-λτeh） is introduced. The main contribution of the present work is the introduction of integral transforms which provide the calculation of expectation value of energy and the related matrix elements to be done analytically over single-particle coordinates instead of hvlleraas coordinates.
