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。

The roof was poor and thatched; but in strange contrast to it there ran all along under the eaves a line of wooden shields, most gorgeously painted with chevron, bend, and saltire, and every heraldic device.

这个屋顶用茅草覆盖很破旧，但是奇怪与之鲜明对比的是位于屋檐底下的一行木构，大部分绘制了锯齿形的雕饰，x十字形和贵族的纹饰。

From the same spot, you can also see a bit of the Sawtooth Ridge that snakes through the heart of the white Trinities, linking together a knife-edge serration of granite peaks overlooking more than a dozen lakes.

在这个地方，你还可以看到群山蜿蜒起伏的向这个三位一体的中心地带延伸过去，他们联在一起，中心地带的一块锯齿状的花岗岩俯视着群湖。

From these result of the experiment, the dynamic modeling can be simulated effectively, when the move speed of tip is faster the shear force in the tip is bigger. In the lithography process the motion of tip influence by the pile up, it leads to the serration surface of the groove, is like the surface of actual material of the cutting process.

由加工成形与磨耗结果回馈，可有效做探针动态建模，并模拟出，当探针移动的速度越快时，针尖所承受的剪应力越大，并且在蚀刻过程中，针尖受表面堆积物的影响，导致沟槽表面类似锯齿形的蚀刻表面与实际加工之情形相似。

The interface between pure Mo and interphase is smooth cycle, and that between pure W and interphase is discontinue one. The boundaries between interphase and TiAl matrix in both composites are serrated in as-cast condition, and the serration disappeares and smooth interphase ring is formed after HIPing.

显微组织研究表明，TiAl/Mo及TiAl/W复合材料在铸态下界面层厚度不大，且大多在TiAl基体中形成和长大，靠近Mo纤维的界面为光滑的环状，靠近W纤维的界面为微观不连续界面，而双方的另一侧以锯齿状向TiAl基体延伸。

Leaf margin sharply biserrate, abaxially curved pilose, inconspicuously crinite at vein axils.

叶缘锐的具重锯齿，背面的弄弯的具柔毛，难以觉察具长软毛的在脉腋。

Leaves elliptic, obovate, or ovate-lanceolate, sharply and densely serrate; 3 connectives connivent, central connective incurved, nearly as long as lateral connectives; thecae at middle or apical part of connectives
