查询词典 two dimensions

If the observer is at a great distance compared to the other dimensions of the experiment and the rays are nearly perpendicular to the reflecting surfaces, then the path difference between the two waves (corresponding to r1-r2 in the preceding section) is just twice the thickness d of the air wedge at each point.

如果观察者比起实验装置来讲距离较远而且光线较接近于垂直反射于表面，那么这两光波的光程差(在前面所述的相应部分 r1-r2)就仅仅是空气劈尖在该点处的厚度 d 的两倍。

Confirmatory factor analysis was deployed to study the 3~5 years old preschool children's structure of self control, and the results show that it consists of four dimensions: continence, persistence, consciousness and self imposed delay of gratification, the relations among them are isolative and correlative. According to the results, we designed two observing field experiments, and compared the results from experiments and questionnaire, it can be found that these two results with higher conherence, and it shows that the questionnaire has good reliability and validity.

本研究通过编制&幼儿自我控制能力发展教师评定问卷&，运用验证性因素分析的方法得出了3～5 岁幼儿自我控制能力的结构，通过具体的实验验证了问卷的效度，并进一步分析了儿童自我控制的年龄差异和性别差异，简单探讨了幼儿自我控制各个维度之间的关系。

A series of copper halides in one, two, or three dimensions have been successfully synthesized such as rhomboid dimers of stoichiometry [Cu2X2L2]n, the tetranuclear species on cubane or stepped cubane tetramers of stoichiometry [Cu4X4L4]n and hexagonal[Cu6X6] grid chains.2 The main strategy in crystal engineering is a secondary building block approach.3 For a given building block, there are two routes to construct frameworks.

Beijing-a super-large city, streets, buildings and plazas here have larger dimensions than a small city-Sichuan. In Beijing a giant city space is divided and wrapped by reinforcements, cement and glass curtain wall; apparently, their existences intend to accommodate more people to live and work in, however, they change ways of direct communication between human and human-all things in a regular order and become indirect and circuitous. E.g., two persons looking at each other on two sides of a street have to bypass a long way to cross over a rail fence in the middle.

身处北京这样的特大型城市，这里的街道、楼宇和广场在规模上有着远比四川小城更大的体量，它们用钢筋水泥和玻璃幕墙把诺大的城市空间分割和包裹，表面上看它们的存在是为了能够容纳更多的人生活和工作于其中，实际上却更加改变了人与人之间相互交流和沟通的直接方式--一切都变得有条不紊，都变得间接和迂回，连马路对面想望的人，都要绕行很远，才能跨越中间的护拦隔离带相聚。
