亮度

Its brightness peaked in May with an apparent magnitude of about 3 and slowly declined in the following months.

这颗星在5月达到最亮，亮度3级，然后就慢慢的黯淡下去了。

The galaxy has an apparent magnitude of +9.0, making it easily visible with amateur telescopes.

该星系的亮度为+9.0，用小型的天文望远镜就可以看到它。

The apparent brightness, or magnitude, of the stars is shown by the sizes of the dots, graded by appropriate numbers.

明显的亮度，或规模，明星是所表现出的大小的点，通过适当的梯度编号。

Omega Centauri is also the brightest globular cluster, at apparent visual magnitude 3.9 it is visible to southern observers with the unaided eye.

半人马座欧米伽星团也是最明亮的球状星团，其亮度大小显示为3.9星等，在南半球的观察者用肉眼就可以欣赏它了。

This paper lays stress on the establishment of the optical system model of solar simulator and xenon short arc lamp model, especially the later.

文章着重介绍了太阳模拟器光学系统及氙灯的建模，尤其对短弧氙灯建模做了详细阐述，它是根据短弧氙灯的亮度分布图采用多个体光源嵌套的形式模拟氙灯，用角度切址文件和光谱分布数据定义短弧氙灯的角度分布和光谱分布。

下面是默认设置下的jpeg亮度和色度的对比图表，每个都有对应的jpeg标准质量系数。

Orion KL hot molecular core is known to be rich in organic molecules; the brightness ( 105L ) and proximity ( 450 pc) of Orion KL make it a primary target for molecular line search and astrochemistry study.

猎户座KL热分子云核是个已知富含有机分子的天体，它的亮度(~ 105 Lsun)以及相对於太阳如此近的距离(~ 450 pc)非常适合我们来寻找在太空中尚未被指认出来的重要分子以及做天文化学上的研究。

In the catalyst after leaching, other than nanoscaled Ni crystallites, boundary area is observed from HREM. These areas are low contrast and high brightness. The atomic density of these areas should be low, therefore, it is suggested that they are rich in voids and phosphorus atoms.

高分辨电子显微观察显示，合金脱铝形成镍纳米晶的同时，还形成了纳米尺寸的低密度、高亮度的界面区域，该区域与其它文献中提到的孔洞尺寸相当，但认为它应该是富含铝及大量缺陷的结构疏松区。

The third approach is about the concept of an ITO direct Ohmic contact structure on GaP window layer. The direct Ohmic contact structure is performed by the deposition of an AuBe diffused thin layer and the following activation process on the surface of a Mg-doped GaP window layer. The presence of this thin AuBe diffused layer yields the Be dominant metallic surface layer and significantly reduces the barrier height between the ITO and p-GaP layer. Via the modification of contact structure, not only the brightness was significantly increased but the reliability was comparable to the conventional LED without this structure.

第三个研究为一种具有直接欧姆接触在p型磷化镓窗层与氧化铟锡界面的制程方法，於本研究中并无习知砷化镓欧姆接触层的存在，我们利用金/金铍金属藉由热退火程序，使其金铍原子在磷化镓窗层表面形成具金属特性之薄膜层，降低磷化镓与氧化铟锡接触产生之接面能障；另外，该元件在氧化铟锡直接欧姆接触於磷化镓窗层下，除亮度具明显提升外，在稍大电流(20毫安培)元件可靠度测试下，亦未有明显衰减情形发生。

For a particular region, in conformity with it's function, the period of time, it's indoor brightness and it's purpose of use, the intelligent lighting control system can automatize the lighting system with the integrated technologies of computer, communication and digital light regulation.

智能照明控制系统，就是根据某一区域的功能、时段，室内光亮度或该区域的用途，用计算机技术和通讯技术及数字调光技术相结合，使照明系统自动化。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
