无叶的

The research for the three-photon correlated imaging with incoherent light of lensless Fourier-transform is reported.

首次从理论上提出了利用非相干光场在无透镜的情况下，得出高阶干涉光的三阶关联函数解析式，并证明了非相干光场通过傅里叶变换，完全能够实现多光子的关联成像。

Small tufted perennial herb of mountains of central and southern Europe having very small flowers of usually leafless stems; sometimes placed in genus Lepidium.

在欧洲中部和南部的山上长的小穗的多年生杂草，具有非常小的花，通常枝干无叶。

Leaf reflectance spectra (400–800 nm) were measured to provide an in vivo non-destructive assessment of pigments in leaves during ontogenesis.

与其他发育阶段的叶片相比，幼叶的NPQ及Car/Chl比值较高。400-800 nm叶片反射光谱为活体无损伤检测叶片发育过程中其色素含量的变化提供了一种方法。

The sister-group relationships are strongly supported between Petrosaviaceae and the remaining monocots (except for Acoraceae and Alismatales s.l.), between Dioscoreales and Pandanales, and between Commelinales and Zingiberales in the combined analyses of two genes and three genes.

继无叶莲科之后分化的类群形成两个大的分支：一支是由露兜树目和薯蓣目构成，二者形成姐妹群关系；另一支是由天门冬目、百合目和鸭跖草类复合群组成，三者之间的关系在单个序列分析和联合分析中不稳定，需要进一步扩大取样范围来确定。

It caused symptomless infection on garlic, onion, shallot, Welsh onion, Chinese leek, and pea, local lesions on Chenopodium amaranticolor, C. quinoa, and Tetragonia expansa, or systemic necrosis on broad bean, but did not infect leek, narcissus, lily, belldonna lily, tobacco (5 species), Gornphrena globosa, and Physalis floridana in host range test. The virus was propagated in Chinese leek and assayed in C.

其寄主范围包括大蒜、洋葱、葱、韭等葱科作物，但呈无病徵系统性感染，唯不感染韭葱；其他寄主反应包括：红藜、Chenopodium quinoa、及番杏接种叶的局部病斑，豌豆的局部潜隐感染，蚕豆的系统性坏疽等。

At least basal leaves dentate, serrate, or pinnatifid; median filaments free; stems glabrous or with straight trichomes.

至少基生叶具牙齿，使成锯齿波，或羽状半裂；中间的花丝离生；茎无毛的或具直的毛状体。

These findings indicate that there is plasticity in response to micro\|habitat heterogeneity along the continuous moisture content gradients of sand dunes at the ramet population and clonal fragment levels.

结果表明，准噶尔无叶豆对沙丘坡面水分条件连续变化的异质性小生境存在分株种群及克隆片段两个等级的可塑性响应，并通过可塑性变化适应了沙丘坡面水分条件的分异。

And the extreme centrifugal force from the enlarged higher impeller stops the solution as it entering the higher impellr. At the same time, the full solution in the chamber stops the air mixed with the solution in the chamber to go down. This way masterly eliminates both big problems of vertical sealless pump, overflow at high pressure and bubbles at big flow.

上部叶轮时，即受加大之背叶的强大阻力而无法上升，但上部叶轮所卷入液体中的空气，却受阻於水室中贮满的液体而无法下降，如此巧妙地排除了立式无轴封泵高压时溢流，或大流量时吸入空气的两大难题。

When pump starts, the lower impeller lifts the solution up step by step. And the extreme centrifugal force from the enlarged higher impeller stops the solution as it entering the higher impellr. At the same time, the full solution in the chamber stops the air mixed with the solution in the chamber to go down. This way masterly eliminates both big problems of vertical sealless pump, overflow at high pressure and bubbles at big flow.

塑宝SV泵剖面结构SV Super Series Analytical cross section SV泵剖面结构泵开始运转时，底部叶轮将液体逐步上推，待液体进入上部叶轮时，即受加大之背叶的强大阻力而无法上升，但上部叶轮所卷入液体中的空气，却受阻於水室中贮满的液体而无法下降，如此巧妙地排除了立式无轴封泵高压时溢流，或大流量时吸入空气的两大难题。

Leaves lanceolate to ovate-lanceolate, short petiolate to subsessile; corolla usually creamy white to reddish, purple spotted.

叶披针形到卵状披针形，对近无柄的短叶柄；通常的花冠乳白色的到带红色，紫色斑点。

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。
