康普顿效应

In the DU FEL, an additional undulator with period close to the betatron wavelength in the main undulator is introduced to provide an additional mechanism of bunching.

我们建立起了包含了空间电荷效应的DU-FEL非线性理论，并在此基础上对高增益康普顿区及喇曼区DU FEL的增益及转换效率进行了解析分析和数值模拟研究。

First, the background spectrum is subtracted from experimental one; Second, by the spectrum stripping, the counts came from partial energy deposition of incidence photon in HPGe crystal, such as Compton scatting or pair production; the next, transform the experimental spectrum to the incidence photon flux spectrum.

实验数据的处理过程有三步：1 从实验谱中减掉本底谱；2 实验谱中分离掉各种能量的入射光子在晶体中的部分能量沉积(康普顿散射、电子对效应)：3 处理过的实验谱转成入射光子通量谱。比较结果显示，在本实验中，模拟谱对实验谱的总计数相对偏差不大于20%，两者基本符合。

The researches include the dense medium effect on the evolution of afterglows, constraints on the physical parameters of GRBs, the origin of the energetic gamma-ray emission from GRBs, the inverse Compton spectra in the very early afterglows, and energy source mechanism of the supernova-GRB connection.

研究工作主要包括：γ暴周围环境对余辉演化的影响、γ暴的物理参数的限制、极高能γ射线的起源、极早期外激波区域的逆康普顿散射光谱与观测效应以及γ暴与超新星关联的理论解释。

By using Rh Kα compton scattered radiation as internal standard and mathematical correction, the matrix effect has been eliminated successfully for some elements.

为了克服基体效应，对某些元素采取了铑靶Ka线康普顿散射强度比值法和数学校正法联合校正，成功地克服了基体的影响。

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.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
