工艺特点：凹凸压印加工是一种常见的制卡和会员卡制作品表明装饰工艺，他使用图文信息相互匹配的凹凸印模，通过机械作用使印品表面对应处基材发生永久性挤压变形后，在印品表面形成立体图文，近年来随着电子雕刻和激光雕刻技术的不断提高，凹凸印模的加工水平有了质的飞跃，精雕细凿的凹凸印模使得经凹凸压印加工的印品表面之图文更加惟妙惟肖。

First, for state estimation problem of the linear stochastic systems with uncertainties in both the state matrix and the noise matrix, a new satisfactory estimator is constructed with stochastic theory, which can guarantee that estimator error system with bounded perturbed model parameter satisfies the constraint indexes that is given. Thus a sufficient condition of solving satisfactory estimation is obtained; secondly, the algorithm of designing satisfactory estimator is presented by analysis.
