The wave-front detection technique can amplify the variations of the wave-front of the debris flow. The debris flow becomes easy to discriminate. Based on the clean images processing, the detection ratio of the multiple filtering technique can increases from 56.36% to 95.27%. The noise removal technique can effective remove the pepper-and-salt noise and Gaussian noise. The clean images will reduce the false alarm rate for detection of remaining ratio technique.

土石流波前判识」使用前处理影像，可有效的将土石流波前扰动强度放大，较易正确判识出土石流波前；「多重滤波判识」经影像前处理后，可降低因环境带来的不当讯息，结果发现，其判识率由56.36%大幅提升至95.27%；「溪床特定物残留率」判识时，易将杂讯视为特定物，滤除杂讯可有效降低误判之机率。

In fact, the feature of isotropically metallic property at this filling is discerned from the experiment. Besides, through a simplified model, we prove that there is a discontinuous phase transition from the bubble state to the stripe state when the filling factor increases.

最后，在有平面内磁场的情况下，类比于Laughlin波函数，我们试图构造一种朗道规范下的分数量子霍耳态的变分基态波函数，这一波函数的有效性有待于进一步的精确对角化计算的验证。

As to the higher Landau levels, we conducted systematically calculations for the various possible ground states, such as the Laughlin liquid, the composite fermion liquid, the Wigner crystal, and the charge density wave . We find that when the Landau level index N≥2, the fractional quantum Hall states are ruled out and the CDW and Wigner crystal dominate. An exception occurs at around v=4+1/6, where the composite fermion liquid may be more energetically preferable than the CDW and the Wigner crystal states. This result provides a new explanation to the so-called re-entrant integral quantum Hall effect. In fact, the feature of isotropically metallic property at this filling is discerned from the experiment.

对于高朗道能级，我们对各种可能的基态，比如量子霍耳态，复合费米子流体，Wigner晶体，电荷密度波等，做了系统的计算，我们发现，当朗道能级N≥2时，分数量子霍耳态不再出现，Wigner晶体和电荷密度波将占主导地位，一个例外就是在ν=4+1/6附近，复合费米子流体可能出现在从Wigner晶体到电荷密度波晶体之间，该结果为上述的重进入整数量子霍耳效应现象提出了一种新的解释。

The accent of Robert Walpole told people he came from Norfolk; Robert Peel, born in Bury, was recognisably Lancashire to the end; you can hear the tang of Liverpool in early recordings of Gladstone.

操着罗波特·沃波尔口音的人说自己来自于诺福克，罗波特·皮尔，出生在巴瑞，最后却被误认为是兰开夏人，因为在早期的格拉德斯通录音带上我们能听到他浓重的利物浦口音。

Under the background of High Power Microwave technology, a novel family of waveguides for high power microwave transmission is proposed. Some other new types of guided wave structures formed by some classical geometrical curves are also explored in this dissertation.

MCS-96单片机要用PWM产生锯齿波，应使PWM寄存器中的值线性增加，那么在PWM输出端将得到宽度线性增加的脉冲波，经滤波后，便可得到锯齿波。

The result shows that gravity wave excited by the tropopause forcing can propagate stably to the mesosphere through the stratosphere so that the energy and momentum can be transferred from a region to another. In the propagation, gravity wave undergoes growth, overturning, convection and breaking. The breaking of gravity wave is the important source of convection and smallscale waves, and convective instability and overturn are the character of nonlinear phenomenon.

分析结果表明，从对流层顶激发的重力波能稳定地经平流层传到中层顶，从而将能量和动量从一个区域带到另一个区域；在向上传播过程中，重力波经历了发展、位温翻转、对流直至最终破碎的演变；重力波的破碎是对流和小尺度波动的重要的源，对流不稳定和翻转是非线性现象的一个基本特征。

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.
