作为一种具体的实施方式，所述玻璃由ZnSnO层、Ag层、NiCr层、ZnSnO层、Ag层、NiCr层及Si3N4层依次层叠在所述玻璃基板而成。
作为另一种具体的实施方式，所述玻璃由ZnSnO层、Ag层与Cu层复合层、NiCr层、ZnSnO层、Ag层、NiCr层及Si3N4层依次层叠在所述玻璃基板而成。
优选地，所述玻璃基板为普通玻璃或钢化玻璃。
由于上述技术方案的运用，本发明与现有技术相比具有下列优点：本发明中的单向透视低辐射玻璃，其中通过在玻璃基板上依次镀设复合电介质层、第一金属反射层、阻止金属氧化层、中间复合介质层、第二金属反射层、光吸收层及复合介质保护层，并对各层的厚度进行配置，能提高单向玻璃观察对象面光线的反射率，减低观察面光线的反射率，减少观察干扰，兼具单向透视和低辐射性能。

具体实施方式
下面结合附图和具体实施例来对本发明的技术方案作进一步的阐述。
参见图1、图2所示，本发明的单向透视低辐射玻璃，该玻璃包括玻璃基板1、沿玻璃基板1的厚度方向依次设置的复合电介质层2、第一金属反射层3、阻止金属氧化层4、中间复合介质层5、第二金属反射层6、光吸收层7及复合介质保护层8，其中玻璃基板1可采用普通玻璃或者钢化玻璃，也可以为本领域内常用的其他类型的玻璃。玻璃基板1的一侧表面设置有上述的各层，另一侧面为该单向透视玻璃的外表面，也为观察对象面。
复合电介质层2能有效地加强玻璃基板1与第一金属反射层3的结合强度，同时还可以通过该复合电介质层2的颜色调节，降低光线的透过率，从而降低光线从玻璃基板1射向第一金属反射层3的强度。该复合电介质层2可为SiNx层、SnO2层、ZnSnOx层、TiOx层、ZnO层中任一层，也可以为SiNx层、SnO2层、ZnSnOx层、TiOx层、ZnO层中至少两层叠加而成。该复合电介质层2的厚度优选地为4-50nm。
第一金属反射层3能够将从玻璃基板1射来的光反射，使玻璃基板1即管材对象面无法透视到相对面，该第一金属反射层3为Ag层、Al层、Cr层或Cu层，或者由为Ag层、Al层、Cr层及Cu层中的至少两层叠加而成，该第一金属反射层3的厚度优选地为10-30nm。
阻止金属氧化层4叠加设置在第一金属反射层3的表面，能有效地组织第一金属反射层3与空气接触而发生氧化，保证了第一金属反射层3的可透视性和反光性能。该阻止金属氧化层4为NiCr层、Nb层或Cr层，其厚度优选地为0.5-10nm。
中间复合介质层5可为SiNx层、SnO2层、ZnSnOx层、TiOx层、ZnO层中任一层，也可以为SiNx层、SnO2层、ZnSnOx层、TiOx层、ZnO层中至少两层叠加而成。其厚度优选地为30-90nm。
第二金属反射层6用于增强单向透视玻璃的低辐射性能，该第二金属反射层6为Ag层、Al层、Cr层或Cu层，或者由为Ag层、Al层、Cr层及Cu层中的至少两层叠加而成，其厚度优选地为5-20nm。
光吸收层7能有效地使光线在其界面发生折射，降低光线的反射率，并使光在穿透该光吸收层7的过程中被吸收，从而降低该单向透视玻璃与玻璃基板1相对的外表面（亦即观察面）光线的反射率，实现透视效果，并减少观察干扰。该光吸收层7可为NiCr层、Nb层或Cr层，其厚度为0.5-20nm。
复合介质保护层8能够有效地对光吸收层7起到保护作用，使得该单向透视玻璃耐用，不易损坏，同时还可以通过该复合介质保护层8的颜色调节，提高光线的透过率。该复合介质保护层8可以为SiNx层、SnO2层、ZnSnOx层、TiOx层、ZnO层中任一层，也可以为SiNx层、SnO2层、ZnSnOx层、TiOx层、ZnO层中至少两层叠加而成，其厚度优选地为10-60nm。
以下以具体的实施例来说明本发明的单向透视玻璃的性能：
实施例1：
参见图1所示，该单向透视玻璃的结构为普通白玻璃基板/ZnSnO层/Ag层/NiCr层/ZnSnO层/Ag层/NiCr层/Si3N4层，各层的厚度依次为6mm/33.5nm/25.0nm/7.7nm/76.2nm/11.1nm/1.3nm/21.4nm。可通过磁控溅射工艺依次将各层膜层镀设在玻璃基板1上，其中使用14个交流旋转阴极，5个直流平面阴极，共19个阴极进行生产。
产品的性能测试如下：
玻面(观察对象面)的光反射率：56％，透过颜色：a*＝-3.9，b*＝-0.09；
膜面(观察面)的光反射率：18％，反射颜色：a*＝-15，b*＝-33；
观察面的光透过率：24％；
辐射率：0.02。
实施例2：
参见图2所示，该单向透视玻璃的结构为普通白玻璃基板/ZnSnO层/Ag层/Cu层/NiCr层/ZnSnO层/Ag层/NiCr层/Si3N4层，其中，每层的厚度为6mm/17.2nm/19.0nm/6.3nm/4.4nm/82.6nm/15.6nm/0.7nm/33.4nm，该单向透视玻璃中采用Ag层31与Cu层32叠加形成第一金属反射层3。可通过磁控溅射工艺依次将各层膜层镀设在玻璃基板1上，其中使用12个交流旋转阴极，6个直流平面阴极，共18个阴极进行生产。
产品的性能测试如下：
玻面(观察对象面)的光反射率：50％，透过颜色：a*＝-0.28，b*＝-3.26；
膜面(观察面)的光反射率：14％，反射颜色：a*＝3.5，b*＝-13；
观察面的光透过率：30％。
辐射率：0.02。
综上，可以看出，该单向透视低辐射玻璃结构牢固、紧凑、简单，能提高观察对象面光线的反射率，减低观察面光线的反射率，减少观察干扰，兼具单向透视和低辐射性能。
