为了有效地控制簿带的加工过程(例如镀敷、层压,造纸等),必须对加到运动中的簿带上的材料量进行测量。Barber-Dolman I-ndev's 6880型微机测量系统正是为此种测量目的而开发出的。不过,它的初型设计存在一些问题,即当簿带线速度有变化时,系统的多个扫瞄器难以实现每次对带上的同一点测量。现在已由在系统中引入 Multibus Ⅰ型运动控制插件而得到解决。

Given an integral M-currrent To in Rm+k and a tensor H of type(m.l)on Rn+k with values orthogonal to each of its arguments we proved in a previous peper[3]the sxistence of anintegral m-current T =γ(M,θ.ζ)with boundary T0 and mean curvature vector H by minimizing an appropriate functional on suitable subclasses of the set of all integral *** thes paperwe discuss the existence and structure of oriented tangent cones C of T at points x∈spt(T) spt(T),especially we show that C is locally mass minimizing.

Difluoromethyl ethers are formed through mechanochemical reactions of alcohols with difluorocarbene in a mixer *** protocol could be applied to primary,secondary,and tertiary alcohols,yielding the corresponding products in excellent yields(up to 99%)after 1 h reaction time at room *** transformations proceeded under solvent-free reaction conditions,followed by product purification by filtration,which drastically reduced the amount of waste generated during the process.
