查询词典 plane concave

Solid desiccants Solid desiccants are characterized by an internal porous structure that contains very large internal surface areas with very small radii of curvature. The equilibrium partial pressure of water vapour above such concave surfaces is much less than that above plane surfaces and so solid desiccants exhibit a very great affinity for water.

坚实干燥剂坚实干燥剂为包含非常大内部表面以非常小半径曲度的一个内部多孔结构描绘。water.vapour 平衡部份压力在这样凹面表面之上是较少比那在平面表面之上和因此坚实干燥剂陈列非常巨大亲合力为水。

By means of using a disc cutter with a concave end instead of traditional ball-ended or flat-ended ones,and adjusting the cutter axis to move relatively to the component being machined according to some special rules,the envelop formed by the trace of the tool-nose in each pass and the required surface have the same derivatives up to the second order in the plane normal to the feeding direction.

采用二阶密切曲率法，即采用中凹的盘形铣刀取代传统的球头或鼓形铣刀，在每一行程中让刀具轴线相对于工件按特定的规律摆动，使得在垂直于进给方向的法截面中，由刀尖轨迹形成的包络面与理论曲面的法截线具有相同的1阶？

In order to effectively control fabric quality in the wet processing such as dyeing, printing, finishing and design a fabric which has better thermal-moisture com fort, this paper has proposed the theoretical basis and method for measuring capillary radius distribution along fabric plane based on the equilibrium between Laplace pressure of concave in front of capillary liquid and hydraulic pressure of liquid column by weight classification differentials.

为有效控制染色、印花、后整理等织物湿加工过程中的产品质量并设计出具有较好热湿舒适性能的服装面料，根据在织物毛细孔中液体前沿弯月面的Laplace压力和液柱静压间的平衡关系，提出基于质量分级和差减数据测定沿织物平面毛细孔径分布的理论依据和方法。

This paper presents an experimental study of the anti-misalignment stability and the output characteristics of the corner cube cavity laser compared with the piano-concave cavity and the plane-parallel cavity lasers.

对角隅腔激光器的输出特性和抗失调稳定性进行了研究，并与平凹腔和平平腔激光器进行了比较。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
