查询词典 at the distance

Measure of uniformity is essential for constructing uniform design. Based on the distance concept, one kind of new distance function-potential function is introduced and used to measure the uniformity of points distributed in a general convex polyhedron.

均匀性度量是构作均匀设计的基础，本文从距离概念出发，通过对称的方法，得到一种新的距离函数－势函数，并将势函数作为衡量任意凸多面体上布点均匀性好坏的准则。

Clearance is the shortest distance between conductive circuits; creepage is the distance between conductive surfaces along the surface.

间隙是导电电路之间的最短距离，爬电距离是沿物体表面之间的导电表面的距离。

He paused - and growing cooler in a moment, added, with only sarcastic dryness, 'if mr. perry can tell me how to convey a wife and five children a distance of an hundred and thirty miles with no greater expense or inconvenience than a distance of forty, I should be as willing to prefer cromer to south end as he could himself.

他停顿片刻，变得越来越冷漠，然后用讽刺的腔调干巴巴地补充道："如果佩里先生能告诉我，如何带着妻子和五个孩子走一百三十哩路不比四十哩路多花一个子，也丝毫没有什么不便，我倒很乐意向他那样到克罗摩尔海岸而不去南方。"

Research usejP.Haggett"s pattern of spatial structure and system, analysis technique of tourism market space and data of spot check to analyze the evolvement of spatial structure and problems of tourism development from six faces, move, path, crunode, significance of crunode, ground and diffuse. The law of the evolvement of spatial structure: First, tourism development keeps rising. Second, AR of xi"an is very big and stable, Xi"an is tourism hotspot and center. Third, origin market space sticks out east, and isn"t continuous. Fourth, tourist proportion of XAZ follows the low of distance decay. Distance decay is very obvious in adjacent zone because of little attraction. Sixth, the spatial distribution of tourist origins has become less concentrated. Tourist origins of east China develop quickly. Three problems: First, tourism development is very unbalance between Xian and its adjacent zone.

西安及毗邻地区的国内客源市场空间结构的研究，采用了英国著名地理学家哈格特描述的空间结构模式与秩序，利用旅游市场空间分析技术，借助市场抽样调查、数量分析，从运动模式、路径、结点、结点层次、地面和扩散6个层方面进行了剖析，归纳总结出5个客源市场空间结构演变规律：(1)旅游业发展整体保持增长趋势；(2)客源吸引半径大而稳定，西安市是全国性的旅游热点城市和旅游中心城市；(3)客源市场分布突向东部，呈不连续分布；(4)游客比重的距离衰减普遍存在，毗邻地区吸引物及自然吸引物吸引力较小，距离率减明显；(5)客源集中度减小，客源市场发展呈现跳跃式增长的演变规律。3个市场拓展面临的问题：(1)西安与毗邻地区间旅游业发展不平衡现象明显；(2)客源市场区位不佳；(3)旅游产品单一老化，类型单调乏味。

It is found that there is a critical value (25mm) for the distance from the nozzle to the skin surface when the spray time is 40 ms. If the distance is too far or too near, heat extraction process will have different characteristics. The results could provide an applicable method for guiding the Cryogen Spray Cooling of laser therapy.

发现喷雾时间在40ms时，喷嘴到皮肤的距离具有一临界值（25mm），大于或小于此距离喷雾与皮肤的换热作用具有不同的特性，研究结果对于将制冷剂喷雾冷却实际应用于激光治疗鲜红斑痣手术具有重要的指导意义。

My house is now one year old baby and eight days, and now school二指pinch objects, recognize facial features, using a small barbed Zaza massage ball to her, and bound feet massage, baby to find her mother to identify more with your baby out of touch with nature and more and contact with children, to identify the number of baby fingers, etc., to the baby building blocks, so that he felt percussion, the small things will be in a cup, so that your baby from the inside out, add into your baby's choice training, the cup mouth cover, shake a distance, in holding an empty cup, shaking a distance, so that the initial awareness of cause and effect relationship between the baby because I did not bring his notes, we have only had the three classes, can only introduce so much, I hope useful for you!
