A new type of high-birefringence photonic crystal fiber is brought forward, and the method introducing circinal holes with different sizes or elliptical holes which is used to design high-birefringence photonic crystal fiber is replaced by introducing fluorine-doped solid circles.

提出了一种新结构的高双折射光子晶体光纤，通过引入掺氟实心圆的方式形成双折射，而不采用大多数高双折射光子晶体光纤中引入不同孔径空气孔或椭圆空气孔的结构。

It is found that the characteristic equations for right hand and left hand circularly polarized waves are identical.

在这种波导中，右旋和左旋圆极化波的特征方程是相同的，因此，它们的传播常数也是一样的；而当线极化波通过这种波导时，不出现极化面的旋转。

It is of medium length, neither cobby nor slack from excessive length.

中等长度，不能因为身体过长而变圆或松弛。

4 Names of buildings or of types of vehicle (the red lion, the colosseum, a ford cortina).

斜体不用于建筑物的名称或车辆类型(如红狮、古罗马圆型剧场和福特考蒂纳车)。

Petiole 5-8(-12) mm; leaf blade leathery to thickly papery, elliptic or oblong-elliptic, 6.5-10(-15)× 3-4(-6) cm, base cuneate or acuminate, margin entire to crenulate, apex acute or acuminate, sometimes shortly caudate; lateral veins 7-9 pairs, not evident, slightly curving forward, redividing and disappearing before reaching margin.

叶柄5-8(-12)毫米；叶片革质的到厚纸质，椭圆形的或长圆状椭圆形， 6.5-10(-15)* 3-4(-6)厘米，基部楔形或渐尖的，边缘全缘对渐尖的具细圆齿，先端锐尖或渐尖，有时短尾状；侧脉7-9 对，不明显，稍弯曲寄，重新分配和在到达边缘前消失。

Apical internodes of rhizome inconspicuous; calyx 4-7 mm; leaf blade 2-15 cm, margin undulate-dentate, crenulate, crenate, dentate, or repand; pedicel to 2.5 cm.

顶端根状茎节间不明显；花萼4-7毫米； 2-15厘米的叶片，边缘波状具牙齿，，具圆齿，具牙齿，残波状的或；花梗到2.5 厘米 79

The fre-quency equations are derived according to stress match, consid-ering gear as a thin bar and adopting exponential horn. Then the influences of vibration of transformer which consists of horn and gear are explored, which come from the length of horn and the machining frequency. It has been discovered that the reso-nance frequency of the horn is the detune one of transformer and the resonance frequency is not same as one of horn, which provide theoretical rules for transformer design.

鉴于此，根据应力耦合，将齿轮作为圆盘，采用指数型变幅杆，推导频率方程，对变幅杆的设计长度和变幅器振动频率进行数值分析，发现变幅杆的共振频率恰好是变幅器的失谐频率，变幅器的共振频率与变幅杆的固有频率也不相同，这能够为超声珩齿变幅器的设计提供理论依据。

Leaf blade crenate or entire; leaf axils without branches; calyx lobes eglandular ciliate, otherwise often glandular hairy; corolla blue, purple, rarely white, lobes apically not thickened and erect to slightly patent

叶片具圆齿的或全缘；没有分枝的叶腋；萼裂片无腺体的纤毛虫，否则通常腺毛；蓝色，紫色，很少白色的花冠，裂片顶部不加厚和直立给开展稍 5 Pseudolysimachion spicatum 穗花

Corona lobes usually erect, turgid, adnate to and not exceeding gynostegium, rarely ± spreading, circular.

副花冠裂片通常直立，肿胀，而不超过合蕊冠，很少多少开展，圆的贴生于。

Both three-dimensional chiral compounds have intriguing chiral channels, which are built up of homochiral intertwined double helices. The circular dichroism spectra of 1 and 2 in water have shown they are stable in solution, which document they will be significantly useful in asymmetric catalysis and chiral medicine.

以Keggin结构多金属氧酸盐为建筑单元，通过手性的铜-脯氨酸配合物作为模板剂构筑了2个基于Keggin结构多金属氧酸盐的3D纯手性化合物，化合物1和2是一对对映体，代表了世界上第一例3D手性多酸化合物，具有由同手性螺旋缠绕形成的手性孔道，水溶液中的圆二色谱表征这个3D手性化合物可稳定存在，显示这个物种可以在不对称催化及手性药物方面有潜在的巨大的应用价值。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
