five-holes shadowless lamp

By using two equation models of high Reynola number K-?, this pape r makes research on the diameter of the Shadowless lamp in first-level clean op erating room from the two aspects of controlling the diffusion scope of the poll utants and guaranteeing the degree of turbulence, which is helpful to select the diameter of the shadowless lamp in operating room.

采用高雷诺数K-ε二方程模型,从控制污染物的扩散范围和保证工作区乱流度这两个指标出发,对Ⅰ级洁净手术室内无影灯直径进行了研究,为无影灯直径的选型提供了依据。

Objective To introduce a new field-based operating astral lamp.

目的:介绍一种新型野战型手术无影灯。

The clean flow field in operating room which is equipped with no-lamp,traditional shadowless lamp or hollow LED shadowless lamp is modeled in three-dimensional and numerically simulated.

对空载、配置有传统无影灯及中空式LED无影灯的手术室的洁净气流流场三维建模并进行数值模拟。

Although I never saw it projected, I had held it up to the light countless times.

虽然我从来没有看过这张幻灯片的投影，但曾经无数次把它对着亮光观看。

It is transparent when held against white lamp light, and the animal patterns drawn on the porcelain seem to move freely.

经乳白色灯光照射，透明见影，器壁上的鱼，仿佛游在水中，若隐若现，美妙无比。
