A new type of x-ray lens composed of multi-square polycapillary slices (ASPXRL) used in focusing parallel x-ray beam was presented in this paper.Compared with conventional x-ray polycapillary lens,ASPXRL can provide smaller and brighter focus.The effects of the manufacturing imperfections on focusing quality of ASPXRL were evaluated with the values of transmission efficiency and discussed.It is suggested that ASPXRL has application prospects as a condenser lens for x-ray microscopy and flux collectors for x-ray analytical instruments.

Darboux transformation and soliton solutions of a nonlocal Hirota equation
Starting from local coupled Hirota equations,we provide a reverse space-time nonlocal Hirota equation by the sym-metry reduction method known as the Ablowitz-Kaup-Newell-Segur scattering problem.The Lax integrability of the nonlocal Hirota equation is als

A new simplified ordered upwind method for calculating quasi-potential
We present a new method for calculation of quasi-potential,which is a key concept in the large deviation theory.This method adopts the “ordered” idea in the ordered upwind algorithm and different from the finite difference upwind scheme,the first-order li

An extended smart driver model considering electronic throttle angle changes with memory
Based on the fact that the electronic throttle angle effect performs well in the traditional car following model,this paper attempts to introduce the electronic throttle angle into the smart driver model (SDM) as an acceleration feedback control term,and
