查询词典 pascal triangle

Often divided into two types:(1) sine wave oscillator, according to the network oscillation frequency of the different loop selected further divided into RC sinusoidal oscillator, LC sinusoidal oscillators, quartz crystal oscillators, voltage-controlled oscillator, voltage-controlled crystal oscillator and other forms;(2) non-sinusoidal oscillation device, also known as relaxation oscillator, is the use of capacitor charging and discharging and active device (transistor, FET, single-junction transistor, etc.) to generate the pulse-off square wave, rectangular wave, triangle wave, sawtooth wave, or these basic waveforms synthetic waveform and its frequency by the LC time constant charge and discharge circuits to decide.

常分两大类型：（1）正弦波振荡器，根据振荡环路中选频网络的不同，又分为RC正弦波振荡器、LC正弦波振荡器、石英晶体振荡器、压控振荡器、压控石英晶体振荡器等多种形式；（2）非正弦波振荡器，又称张弛振荡器，是利用电容充放电及有源器件（晶体管、场效应管、单结晶体管等）的通断来产生脉冲方波、矩形波、三角波、锯齿波或这些基本波形的合成波形，其工作频率由LC充放电电路的时间常数来决定。

Words like dragon , but , of and phrases like a round triangle have sense, but no referent.

词如龙，但和短语组成的，像一轮三角形的意义，但没有指涉。

Second, it is not possible to find in the world referent for words like but , and , of , however , the , etc. Third, speakers of English understand the meaning of a round triangle although there is no such graph.

第二，它是不可能在世界上找到参照这样的字，但是，而且，然而，等第三，发言者的英语理解的含义，全面三角形虽然没有这样的图。

Neuron of triangle or pyramid shape and with strong refractivity, clear surface, and more than one prominence was adopted for observation.

Adopting the triangle elements to fill the design region, the difficulty to divide irregular design domain by rectangular elements is overcome.

采用三角形单元进行有限元的分析，克服矩形单元对不规则区域划分单元的局限性。

Here, we chose simple polynomials as shape functions, and derive the element matrice on the regular element (a isosceles triangle with a right angle).

这里选取逐渐升幂的简单多项式作为基底函数，并且据此推导了升到六阶的正规单元矩阵。

The result is that center frequency shifts to low-frequency with increase of incident angle under oblique incidence, the band width narrows correspondingly, for both square element arrangement and regular triangle arrangement.
