查询词典 diffuse reflection

The rutile TiO2 powder photocatalyst was prepared by hydrolysis process, and it was coated with WO3 by dipping process using tetrabutyl titanate (C16H36O4Ti) as raw material. The catalysts were characterized by XRD, Raman spectra, TEM and diffuse reflectance UV-Vis spectra.

以钛酸丁酯为钛源，采用水解法制备金红石型TiO2粉体，用浸渍法将制备的TiO2粉体包覆不同浓度的WO3（记为WO3-TiO2），并采用X射线衍射、拉曼光谱、透射电镜和紫外－可见漫反射光谱等手段对所得的光催化剂进行了表征。

Space optical system, especially space infrared optical system, cryogenic optical system and some huge space-based telescopes, all work in the environment where there is strong radiation (such as Sun etc.) out of the field of the system. Because of diffraction of the entrance pupil and diffuse scatter of all inner surfaces, the strong stray radiation will reach the detector of the system.

空间光学系统，特别是空间红外光学系统、低温光学系统以及某些大型空间望远镜，都工作在系统视场外有强烈辐射源的&恶劣&环境中，这些强烈杂光辐射经过光学系统孔径的衍射，以及结构与光学件表面的散射，到达系统像面形成杂光。

The stimulus is perceived in the region just behind the shoot tip. If light falls on only one side of the apex then auxins produced in the apex tend to diffuse toward the shaded side.

光刺激仅仅被芽尖后面的那部分感受到，如果光照射到生长点的一侧，那么生长点产生的生长素就倾向于扩散到另一面。

The filtering blebs were diffuse, intraocular pressure was under 2.40 kPa, none of patients take any drugs to control IOP and there was no silicone oil got into the anterior chamber after operation.

该术式不仅降眼压效果好，而且硅油不易溢入前房，解决了长期以来硅油注入术后高眼压难以处理的问题。

In long spaces, such as road or railway tunnels, underground/railway stations, corridors, and concourses, classic room acoustic theory is not applicable since the assumption of a diffuse field does not hold with the extreme dimensional condition.

在长空间中，如公路或铁路的隧道、地铁站、走廊和交通枢纽大厅，由于对扩散场的假设不适用于其极端的尺寸条件，因此无法应用经典的声学理论。

The bright sun and clear blue sky diffuse somewhat my ominous feeling. The coroners themselves, are not heavy or ceremonial, but completely businesslike as they chat amongst themselves, and prepare to start.

强烈的阳光和洁净的蓝天使我的不祥的感觉扩散开来，这些验尸官们他们自己却不那么沉重也不那么正式，而是在他们谈话并准备开始时，显得生意气十足。

Pachomius manual labour was organized as an essential part of the monastic life; and since it is a principle of the monks as distinguished from the mendicants, that the body shall be self-supporting, external work of one sort or another has been an inevitable part of the life ever since.
