Let K be the Calderón-Zygmund convolution kernel on R^d(d≥2).Christ and Journé defined the commutator associated with K and a∈L~∞(R^d)by T_af(x)=p.v.∫_(R^d)K(x-y)m_x,y^a·f(y)dy,which is an extension of the classical Calderón commutator. In this paper, we show that T_a is weighted weak type(1,1) bounded with A,1 weight for d≥2.

关键词： Christ-Journe type commutator weighted weak type(1 1) A1 weight

An investigation of the properties ofa LiNbO3 photoelastic waveguide via the acceleration-induced effect is presented. A novel three-component hybrid-integrated optical accelerometer based on a Mach-Zehnder interferometer with a LiNbO3 photoelastic waveguide has been designed, which is capable of detecting seismic acceleration in high-accuracy seismic exploration. The Mach-Zehnder interferometer was successfully fabricated and a lighting test used to check its quality. The frequency response characteristic of the accelerometer was measured2 The accelerometer with a resonant frequency of 3549 Hz was demonstrated to show good linear frequency responding characteristics in the range of 100-3000 Hz. The accelerometer also shows good stability and consistency. Experimental results indicate that the outputs of the on- and cross-axis are 147 and 21.3 mV, respectively.

在高原低压缺氧和劳动负荷双约束下,进藏人员作业疲劳相比平原地区累积速率更快、疲劳程度更深,作业风险大。为探究进藏人员作业疲劳问题,综合考虑劳动强度、疲劳症状特征,设计高原作业疲劳自评量表,并于西藏拉萨开展劳动负荷模拟实验,分析不同劳动负荷下主观疲劳度和心率随时间的变化,从主、客观2个方面研究高原作业负荷对机体疲劳的影响。研究结果表明:受低氧环境影响,高原地区不同劳动负荷下呼吸疲劳显著性始终较高(P<0.05);随着作业时间推进,主观疲劳度持续累积,但疲劳增长率逐渐减小;随着劳动负荷增加,心率呈现非线性上升趋势。研究结果可为高原作业疲劳干预、职业健康管理提供参考。

The regularity of the Cauchy problem for a generalized Camassa-Holm type equation is investigated. The pseudoparabolic regularization approach is employed to obtain some prior estimates under certain assumptions on the initial value of the equation. The local existence of its solution in Sobolev space Hs （R） with 1 〈 s ≤ 3/2 is derived.
