锯齿

It has been found that the mat-like crystal is made of zigzag fibrillar structure oriented along the shear direction in the film. The periodical length of the zigzag fibrils is about one micron, corresponding to the width of a band in mat-like crystal.

其锯齿周期的大小平均约为1微米左右，正好与在偏光显微镜正交偏振片下所观察到的草席晶形态中一条晶带宽度的尺寸相当，因此可以认为在偏光显微镜下所看到的草席晶图像只不过是这种锯齿状微纤规则弯曲所形成周期性结构的一种光学效应而已。

Leaves alternate, simple, petiolate, usually doubly serrate, rarely simply serrate, lobulate, or entire; veins pinnate.

叶互生，单，，通常重锯齿，很少仅仅有锯齿，具小裂片，或全缘；羽状脉花单性。

Margins of leaves serrate or coarsely serrate; leaf blade thickly papery or subleathery, often obcordate or obovate, rarely oblong, 2.5–16 × ca. 1.5 cm.

叶有锯齿或的边缘有粗锯齿；经常，叶片厚纸质或近革质或倒卵形，很少长方形，2.5 *约1.5 厘米 9

Petiole of basal and lower stem leaves 3-8 mm; leaf blade pandurate, 5-8 cm; lobes 3-5, terminal lobe ovate, elliptic, or oblong, margin serrate distally, usually double serrate or lobed proximally.

基部和下部茎生叶3-8毫米的叶柄；提琴形的叶片，5-8厘米；裂片3-5，顶生裂片卵形，椭圆形，或长圆形，边缘有锯齿上部，浅裂下部的重锯齿的或的通常。

Leaves simple, alternate, opposite, or verticillate, not stipulate, or sometimes with stipular glands at base of petiole, petiolate or sessile, pinnately veined, margin serrate to nearly entire, teeth often glandular-mucronate.

单叶，互生，对生，或者轮生，不具托叶，或者有时在叶柄基部有托叶状腺体，有叶柄或无叶柄，羽状叶脉，边缘有锯齿至近全缘，锯齿通常有腺状短尖。

Petiole 8-20 cm, glabrous; leaf blade 5-7-foliolate; leaflets sessile, abaxially green, oblanceolate, 10-25 × 5-12 cm, abaxially glabrous or with sparse whitish hairs, ferruginous tomentose at base and in axils of lateral veins, base cuneate, margin crenate-serrate with teeth crenulate-serrulate, apex acuminate to subcaudate; lateral veins in 18-25 pairs.

叶柄8-20厘米，无毛；叶片5-7具小叶；小叶无柄，背面绿色，倒披针形， 10-25 * 5-12 厘米，背面无毛或者有稀少带白色毛的，被锈色绒毛在基部和在侧脉腋处，基部楔形，边圆齿状锯齿具细圆齿到细锯齿的牙齿，18-25对的侧脉。

Leaf blade obovate to broadly so, margin dentate, serrate, or doubly serrate; inflorescence branches and pedicels long glandular hairy; sepals glandular hairy, apex not dentate; petals subspatulate or elliptic.

叶片倒卵形的到宽如此，边缘具牙齿，有锯齿，或重锯齿；花序分枝和花梗长腺毛；萼片腺毛，先端不具牙齿；花瓣近匙形的或椭圆形。

Leaves opposite, usually in many pairs; stipules small; petioles short, connate at base, forming a short sheath; leaf blade elliptic, ovate-elliptic, or elliptic-lanceolate, margin serrate, with 1 gland at serrate tip.

叶对生，通常有多对；托叶小；叶柄短，在基部的合生，形成一短鞘；叶片椭圆形，卵状椭圆形，或椭圆形披针形，边缘有锯齿，在有锯齿端部的具1腺体。

Yun-strip method, the circle-shaped bath temperature higher than the crescent-shaped article transport transport of temperature, the temperature was higher than the crescent-shaped article transport serrated Article transported bath temperature, in the 12mm flat bottom welded seal, using serrated transport of , and with the magnitude and the swinging groove on both sides of the pause, effective control of the bath temperature, so that pore size of the melt is essentially consistent with the roots do not form a welding groove tumor and decrease the chances of burn-through, no penetration has The improvement of the peace panels of the single-sided welding butt welding flat-sided shape is no longer difficult.

运条方法，圆圈形运条熔池温度高于月牙形运条温度，月牙形运条温度又高于锯齿形运条的熔池温度，在12mm平焊封底层，采用锯齿形运条，并且用摆动的幅度和在坡口两侧的停顿，有效的控制了熔池温度，使熔孔大小基本一致，坡口根部未形成焊瘤和烧穿的机率有所下降，未焊透有所改善，使乎板对接平焊的单面焊接双面成形不再是难点。

On the small screen and the number of points will not be dimmed, but results in a strong histologicai, on the contrary, largening, La large pictures are dimmed, and the less obvious point histologicai.

关于点数小，画面并不会变模糊，而是会产生较强的锯齿，相反的，加大点数，拉大图片的话，就会变模糊，而锯齿少明显点。
