使发散

In this paper, firstly we researched the relationships of the communicating distanceand the channel characteristic, the effect of the multiple scattering to the laserpropagation, the requirement of the laser communication to the ATP system and theway to determine the angular dispersion and receive field of view. It is proved that inlight haze weather, letting the input and output laser\'s wavelength are diferrent witheach other, after passing by the filter, it can avoid backward scattering effectually andfor the communication within 15km, the influence of the multiple scattering inatmosphere can be ignored.

Heat, a mode of motion developed by such combustion, was constantly and increasingly conveyed from the source of calorification to the liquid contained in the vessel, being radiated through the uneven unpolished dark surface of the metal iron, in part reflected, in part absorbed, in part transmitted, gradually raising the temperature of the water from normal to boiling point, a rise in temperature expressible as the result of an expenditure of 72 thermal units needed to raise 1 pound of water from 50 degrees to 212 degrees Fahrenheit.

燃烧所引起的运动形式之一--热，不断地、加速度地从热源体传导给容器中的液体，由那凹凸不平、未经打磨的黑色铸铁面把热向周围发散出去；一部分反射回来，一部分被吸收，另一部分被传导，使水的温度从常温逐渐升到沸点。这种温度的上升可作为消费结果标志如下：将一磅水从华氏五十度加热到二百十二度，需耗七十二热量单位。

Theorem 1 If the power series is convergent at ,then for any that ,the power series absolutely converges at point ;if the power series is divergent at ,then for any that ,the power series diverges at point .

定理1 如果级数当时收敛，则适当不等式的一切使这幂级数绝对收敛；反之，如果级数当时发散，则适合不等式的一切使这幂级数发散。

In this paper the structure principle of GM(1, 1) was analyzed and the defect was pointed out that the traditional model only adapt to the data with exponential law, and only can fit for the monotonic data. The prediction is defected when there are two consecutive data unchanged, and 'a' is equal to 0.5 in prediction formula.

从传统GM(1，1)预测模型构造原理出发分析其存在的理论缺陷，此模型适用于具有较强指数规律的序列，只能描述单调变化过程，而且预测数据序列中出现连续两个相等值时将使得a等于0，会使预测数列发散致使预测失效。

Using EMD method, there is bound to be divergent phenomena at the two ends of the upper and lower envelope signal in the data through the three interpolation algorithm, which is end effect. It will affect the quality of EMD decomposition badly, so that the decomposed IMF has no actual physical meaning.

And this paper also shows the structure and parameters of the optical system. The Xenon light of super high voltage is used as interferential source. The position of it is on the focus of the reflector of ellipsoid surface. After reflecting, its lights form a collective point . This point and objective focus of collimation lens are superposition. Though the collimation lens, the beam of light become parallel lights. Then though the Coude Reflector and radiation system of special prism, the lights become a beam of light with 3 ° emanative angle.

该光学系统选用超高压氙灯作光源，使其位于椭球面反射镜的一个焦点上，发出的光线经椭球面反射后所形成的汇聚点与准直负透镜组的物方焦点重合，光束经准直系统后变为平行光束，此平行光束再经库德反射镜和特殊发散棱镜系统，形成具有3°发散角的发散光束，用来干扰敌方设备。

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