Very near the show ring with half a day and half the night scene, distinct yin and yang; eight Koichi Yu also revealed that the digital binary, the Eight Diagrams show that there are significant symbols hidden ancestors of the high-latitude observation background.
极圈附近表演着半年白昼和半年黑夜的景象，阴阳分明；八紘一宇也在显示数码的二进制，表明八卦符号隐显有先民的高纬度观测背景。
Inside benzene or toluene solvent, in the presence of stannous octoate as catalyst and under the conditions of no water, no oxygen, heating and stirring, MPEG and aliphatic cyclic monomer are ring-opening polymerized to obtain binary block MPEG-aliphatic polyester copolymer.
聚乙二醇单甲醚和脂肪族环酯单体，在苯或甲苯溶剂中，在无水无氧，加热和搅拌的条件下，用辛酸亚锡为催化剂，开环聚合得到聚乙二醇单甲醚-脂肪族聚酯二嵌段共聚物。
A binary optical element which is designed to convert a single mode He Ne laser beam into a ring shaped intensity distribution is investigated experimentally.
设计了用于将HeNe激光基模光束整形为环形光强分布的光束二元光学元件；
A binary GA is used in the study on the optimization design of thinned concentric ring antenna array and find a method to improve the efficiency of the optimization design of thinned concentric ring antenna array. 3.
采用了二进制编码的遗传算法，对同心圆环天线阵列的稀疏优化设计进行了研究，通过仿真发现了提高同心圆环阵列稀疏优化设计效率的方法。
This thesis is composed of following sections: In the first section, we present the needed terms and a survey of cyclic codes over rings; In the second section, we discuss the cyclic codes of length 2~e over ring F_2 + uF_2; In the third section, we discuss the dual codes of cyclic codes of length 2~e over ring F_2 + uF_2; In the last section, we obtain two binary codes by Gray map: residue code and torsion code.
本文由以下四个部分组成：第一部分给出必要的术语并综述环上循环码一些相关结果；第二部分就环F2+uF2上2e长的循环码的结构给予讨论；第三部分就环F2+uF2上2e长的循环码的对偶码给予讨论；第四部分利用Gray映射得到两类二元码：residue码和torsion码。
The Mg content increased gradually with the increase of distance from the metal film/atmosphere interface via liquid/ solid binary phase zone to the unmelted electrode. The Mg concentra-tion either in the remelted metal ring, _r, or in the outer layer of remelted liquid metal was less than that in the remelted ingot, _i.
分析结果指出，Mg含量从金属液层/气相界面经液固两相区至原始电极区即随距金属液层/气相界面距离δ_1增加而增加。
