散射角

In order to overcome the difficulties faced on analytically deriving the equation for describing the samll angle light scattering patterns from anisotropic objects with arbitrarily director configurations, a Fast Fourior Transformation algorithm for the calculation of SALS patterns from the anisotropic objects immersed in an isotropic matrix has been developed.

用快速傅里叶变换计算方法( Fast Fourier Transformation，FFT)直接获得高分子材料中介观有序结构小角激光光散射图案，从而对实验获得的球晶和液晶液滴的 SALS图案进行结构预测。

A two cell SBS phase conjugating mirror pumped by pulsed Nd∶YAG laser was experimentally investigated. After returned to YAG amplifer and coupled out by a polariser, SBS output beam had the characteristics of duration tunability and good quality with near diffraction limited far field divergence angle.

对脉冲Nd：YAG激光器抽运的双池受激布里渊散射相位共轭镜进行了实验研究，将相位共轭镜后向反射光束馈入YAG放大级，经放大级放大，由偏振片耦合输出的激光束具有高质量、脉宽可调的特点，远场发散角接近1倍衍射极限。

For unexploded ordnances, the four dimensional unexploded ordnance scattering function of slant range, azimuth, frequency and aspect angle is firstly estimated via the SWD. Secondly, the amplitude information of the multi-aspect feature in different frequencies is extracted, and the spatial distribution information of multi-aspect feature in different frequencies is quantitative described using the Hu moment invariants further.

对于未爆物目标，首先利用SWD得到未爆物斜距-方位-频率-方位角四维散射函数估计，然后在提取了不同频率下的多方位特征幅度信息的基础上，利用Hu不变矩进一步定量描述未爆物不同频率下的多方位特征空间分布信息。

In addition, the excited probabilities of lower exciting states are far off bigger than ones of higher exciting states. The higher exciting states are, the bigger probabilities of big angle scatterings are.

低激发态被激发的几率要远远大于高激发态被激发的几率；激发态越高，大角散射的几率越大。

Transmitted electrons were finally detected by a channeltron electron multiplier operating in single-pulse mode instead of usual measuring current intensity, which can reduce the acceptance solid angle and the contribution of elastic scattering in the forward direction can be minimized effectively.

因采用了恒温控制作用室，以便较准确测量反应室的绝对气压值；同时采用静电型圆柱能量分析器，并用计数率测量模式代替通常的束流强度测量模式，从而可以大幅度减小接收立体角，抑制零度角的弹性散射贡献。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
