If uses SLS double helix to squeeze oar machine and bosomy type or belt to wash oar machine combination to use, can raise black liquor recovery rate 90% above, carrying out a proof is feasible.

倘采用SLS型双螺旋挤浆机和鼓式或带式洗浆机组合使用，可以将黑液提取率提高到90%以上，实践证实是可行的。

The bogie for this crane is of H type weldable bogie, the primary suspension of the bogie is of journal box helical spring and wedge snubbing system.

该机的转向架是一种H型焊接构架式转向架，转向架的主悬挂为轴箱螺旋弹簧，斜楔式减振器。

For example, the spiral arrangement (of scale – bract complexes) is important , thereby passing airborne pollen from one scale to the next.

比如说，螺旋状安排，是重要的，这样才能把空气传播的花粉从一个 s 传播到另一个 s 。

Secondly, according to the stem and leaf anatomy, leaf epidermis, pollen morphology and floral development, it is found that there are no close relations between Acorus and Typhales, especially in the aspect of floral development. In the course of floral development of A. calamus, neither bracteloe primordium nor common primordium occurs in the whole course. Early development of the flower is strongly unidirectional. Three shield carpels develop into a pistil. In Sparganium fallax, each female flower has a bracteole. The bracteole primordium and the floral primordium originate from a complex structure. A single saccate carpel develops into a pistil. In staminate flowers, petal and stamen primordia initiate spirally.

菖蒲属与香蒲目的茎叶解剖特征、叶表皮特征、花粉特征及花器官发生特点等亦存在着明显区别，特别是花器官发生特点差异尤为显著，如菖蒲属花器官发生过程中，没有苞片原基，也不存在任何形式的复合原基，花被与雄蕊原基均以单向性方式发生，雌蕊由3心皮发育而成，具有"盾状心皮"的特点等，黑三棱属则有苞片原基发生，且苞片原基与雌花原基起源于共同的复合结构，雄花的花被原基和雄蕊原基均以螺旋状方式发生，雌蕊由单心皮发育而成，未发现有2或3个心皮原基或其痕迹的现象，体现出"囊状心皮"的特点。

Largely unstructured in solution, linear peptides fold into an amphipathic helix upon binding and insert into the target membrane, leading to breakdown of the transmembranal potential and of ion gradients, thus causing leakage of cell contents, resulting finally in cell death.

大多数的抗菌胜肽在水溶液中是呈现松散的结构，但和目标微生物作用时会褶叠形成双性螺旋的结构并插入其膜内，导致破坏膜内外的电位及离子梯度，造成细胞的泄漏，最后导致细胞死亡。

Long spiral drilling caisson pile is a new driven cast-in-place technique used widely nowadays,which has the characteristics of no earth squeezing and no breast wall needed to be built,but with high load bearing of per pile and high quality of pile forming,etc.

指出长螺旋钻孔灌注桩是近年来日益广泛应用的一种新型灌注桩技术，具有不挤土、无需护壁、单桩承载力高、成桩质量较好的特点。

The simple abstract patterns and spirals of the earliest examples were probably imitating vessels made of a hard stone such as breccia.

简单的抽象的模式和范例螺旋最早很可能难以模仿角砾岩船只由一石如。
