电视阴极射线管在当前是解决显示问题的最好的办法。其他技术都还没有达到它的水平。但是阴极射线管限于30吋的大小。由于真空的体积大,还存在着真空泡被大气压力压碎的危险。
TV cathode ray tube in the present is the best solution to display problems. Other technologies have not reached its level yet. But the cathode ray tube is limited to 30 inches in size. Due to the large volume of the vacuum, there is also the danger of the vacuum bubble being crushed by atmospheric pressure.
