某机载雷达平面裂缝阵列天线的单面阵如图1所示。该面阵布置多路裂缝线源，共分布384处长度各不相同的辐射裂缝，每一路线源均由脊型波导口单独馈电。面阵由辐射板和馈电腔两个零件组成，采用整体钎焊成形。线源结构为非对称单脊共线形式，即在普通单脊波导的两侧与辐射裂缝相对应的位置上布置不对称的凹台。

Geothermal heating Profile Geothermal heating, or to warm, is not higher than 60 degrees Celsius temperature of hot water or heating cables, Buried in the floor under the geothermal system, heating coil of the ground, evenly through the ground to a kind of indoor heat radiation heating methods.

地热辐射采暖简介地热辐射采暖，简称地暖，是将温度不高于60摄氏度的热水或发热电缆，暗埋在地热地板下的盘管系统内加热整个地面，通过地面均匀地向室内辐射散热的一种采暖方式。

In order to understand the effect of UV-B radiation on systematic water metabolism in plants, this review outlined domestic and international achievements in the last 30 years relating to the physiology and biochemistry of plants under UV-B radiation, such as root activity, transpiration rate, water use efficiency, and changes in leaf proline and soluble sugar content at different plant developmental stages. The effect of UV-B radiation on stomatal behavior and related mechanisms including a variety of signal molecule (ABA, hydrogen peroxide, nitric oxide, etc.) content and the role of signal molecules in stomatal activity were also reviewed.

为系统了解UV-B辐射对植物水分代谢的影响，本文从生理、生化两个角度概述了近30年国内外相关方面的研究成果，内容涉及UV-B辐射对植物根系活力、蒸腾速率、水分利用效率及植物不同发育期叶片脯氨酸、可溶性糖含量的影响；总结了UV-B辐射对植物气孔行为的影响及相关机理，包括植物体内ABA、H2O2、NO等信号分子含量的变化以及这些信号分子在调节气孔行为方面发挥的作用。

Devices intended to emit ionising radiation must be designed and manufactured in such a way as to ensure that, where practicable, the quantity, geometry and quality of radiation emitted can be varied and controlled taking into account the intended use.

11.5 电离辐射释放电离辐射的装置的设计及制造再可行时应基于装置的目的确保释放出辐射的数量。几何性质及质量可以被改变和控制。

In this paper, the state equation of simply supported rectangular panel is established by using the control strategy that is canceling the first k radiation modes.

本文利用声辐射模态的特性，通过抵消前k阶声辐射模态伴随系数的控制策略，以四面简支板为研究对象，在声辐射模态领域首次建立了该物体的状态空间数学模型。

According to the atmospheric window,transmission property of infrared irradiation in atmosphere and the impact of the most appropriate temperature corresponding to the optional infrared band on the controlling of the cooperative target's temperature,8～14 μm was identified as the radiation band of the cooperative target.

根据大气窗口、红外辐射在大气中的传输特性和待选波段对应的最佳辐射温度对合作目标温度控制的影响，确定了8～14μm波段为合作目标对应的辐射波段。

The climate space diagram of the tomato in the solar greenhouse is quite similar to that of the cardinal studied by Gates D. M, whereas sun radiation the tomato absorbs is lower than that of the black body.

M。 Gates研究得到的北美红雀气候空间辐射极限图相类似，不同的是，番茄群体吸收的太阳辐射会低于理想的黑体所能吸收的辐射。

The results showed after black radiation background was deducted,two radiation peaks of 2～2.5 μm were present in infrared radiation spectrum of the acupoints.

结果发现扣除黑体辐射本底后，穴位红外辐射光谱上出现 2～ 2 。5 μm和 15 μm两个辐射峰。

By calculation,these two radiation peaks were related to energy metabolism,and the high 15μm radiation peak was identical to wave length in the midpoint of the wave section of 10～20μm high speed tr...

经推算 ，这两个辐射峰与能量代谢有关；15 μm高耸辐射峰与穴处组织 10～ 2 0 μm高效传输波段的中点波长恰好一致；隔附子饼、隔姜和隔蒜三种间接灸的光谱上亦可见 15 μm的高耸辐射峰。

The main work of our research was to study the effects of the combination of enhanced UV-B radiation 0.35w·m~(-2 and Cadmium 1umol·L~(-1 on the growth, photosynthesis, elements absorption and relocation in mung bean seedlings at the initial stage of growth, and the involving mechanisms about the change of photosynthesis under the different treatments were studied also. It was shown that the heights root length, lateral root length, lateral root number, area of leaves, dry/fresh weight of the overground parts and underground part were all inhibited by the single factor and combinative factors.

本文以0.35w·m~(-2)剂量的UV-B模拟增强UV-B辐射和1μmol·L~(-1)Cd~(2+)模拟Cd~(2+)污染，研究了增强UV-B辐射和Cd~(2+)及其复合处理对绿豆幼苗生长、光合作用以及元素吸收和分配的影响，并对不同处理条件下绿豆幼苗光合作用的变化机制进行了比较深入的分析，获得结果如下：增强UV-B辐射和Cd~(2+)及其复合处理8天，绿豆幼苗植株高度、根长、侧根长、侧根数、叶面积、地上部分干/鲜重和根系干/鲜重均下降。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
