锯齿

Stipules ca. 2 mm; leaf margin incised-serrulate; achene ca.

托叶约2毫米；叶缘锐裂有细锯齿；瘦果约1毫米。

Leaf blade margin entire or erose, rarely inconspicuously serrate distally; achene with a purplish ring on both surfaces.

叶片边缘全缘或啮蚀状，很少难以觉察有锯齿；有一枚略带紫色的戒指在两面的瘦果。

A new infinite gas-lubiicated journal bearing with active controlled restrictor is proposed in order to remedy the defects of several existing infinite stiffness at abroad in construction, manufacture and adjusting, which combining surface-restriction with active controlled restriction, make the static and dynamic effect both better.

针对目前国外几种无穷静刚度气体润滑轴承结构复杂、制造难度大、调整困难的不足，本文提出了一种主动控制节流无穷静刚度气体润滑轴承，将表面节流与主动控制节流相结合，使轴承动、静压效果同时获得较好的发挥；利用浅腔及锯齿形多槽结构产生较强的楔形动压效应，提高轴承的静态和动态性能；利用主动控制节流器对轴承进行压力反馈主动控制，提高轴承的承载力、刚度，并在一定载荷范围内，使轴承刚度为无穷大。

Unfortunately, they suffer from several forms of aliasing.

糟糕的是：它们会产生锯齿现象。

Stem strongly grooved, puberulent on angles otherwise glabrous with scattered glands; leaves broadly ovate to ovate-orbicular, apex acuminate, margin coarse serrate or double serrate, apical tooth acuminate; corolla white

茎强烈具凹槽，被微柔毛的在角上或无毛具星散的腺体；重锯齿的叶宽卵形到卵形圆形，先端渐尖，边缘粗糙有锯齿或，渐尖的顶端齿；花冠白色 72 Isodon weisiensis 维西香茶菜

Leaf blade margin serrate or serrate-dentate.

叶片边缘有锯齿或有锯齿有齿。

This paper proposes a switched-mode boost DC-DC converter, which doesn't need not only a saw-tooth wave generator but also an error amplifier. By using a comparator and a fixed duty-cycle oscillator, the proposed controller will offer a high DC voltage of 15V to drive the LED backlight driver for Liquid Crystal Display.

中文摘要本论文提出ㄧ种不需锯齿波产生器和误差放大器的架构，其系利用比较器和输出固定责任比的振荡器来替代锯齿波讯号，藉此控制开关的动作，完成升压式直流电压控制晶片，以提供15伏特直流偏压给小尺寸液晶显示器(Liquid Crystal Display， LCD)。

In addition, the Chinese CRT TV screen points of light, depending on the magnetic field changes in the tilt, So with the need to control the current ramp, triangle wave, This is the same square wave can not ignore the role of function generator is generally automatically generate square wave, sine wave, saw tooth wave and triangular wave, etc. ladder circuit voltage waveform or equipment.

此外，如在电视机中显像管荧光屏上的光点，是靠磁场变化进行偏转的，所以需要要用锯齿波电流来控制，对于三角波，方波同样有这不可忽视的作用而函数发生器是指一般能自动产生方波、正弦波、三角波以及锯齿波阶梯波等电压波形的电路或仪器。

Marked by irregular projections and indentations on the edge or surface.

有不规则锯齿状的或仿佛被咬过一样有锯齿状边缘的。

MCS-96 microcontroller with PWM have Sawtooth, PWM register should be the value of lin...

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。
