查询词典 heading

Physiologically, our model estimated 2.6 days to reach the single ridge stage, 5.6d to the double ridge stage, 11.3d to the stamen and pistil initiation stage, 13.1d to the anther separation stage, 15.3d to the pollen mother cells stage and 18.2d to the tetrad stage. Phenologically, estimations were 13.1d to reach the jointing stage, 28.7d to the heading stage, 32.8d to the grain filling stage and 51.5d to the maturity stage. PDT was consequently used as a unified scale for measuring developmental progress of different cultivars under different climates and cultural practices.

经测算，各大麦品种到达单棱期、二棱期、雌雄蕊分化期、药隔形成期、雌蕊柱头二裂分叉期、雌蕊柱头毛状突起期等顶端发育阶段的生理发育时间分别为2.6、5.6、11.3、13.1、15.3、18.2、28.7d，到达出苗期、拔节期、抽穗期、灌浆期和成熟期等主要物候期的生理发育时间为0、13.1、28.7、32.8、51.5d，形成了不同大麦品种在不同气候和栽培条件下统一的衡量发育的定量尺度。

Yet, unlike Limbo, Ponto , which was in many ways teetered under its own reckless abandon as if Thorpe and company weren't sure which directions they songs were heading – though that may have very well been the point-- their new album is more cohesive and fluid.

不过，不像 Limbo， Ponto 那张由于鲁莽放弃导致从很多方面讲都很脆弱的专辑，那时Thorpe和公司就好像都还不太清楚他们的歌应该是什么方向的——尽管那很可能那就是他们想说的——这次他们在新专辑中更有凝聚力、更流畅。

The effects of low temperature pretreatment and high temperature preculture on the anther culture of non-heading Chinese cabbage were studied, using hybrids '99H Qiu-25'×'99H Qiu-23' and 'Suzhouqing'×'SI' as material.

以不结球白菜杂种一代'99H秋-25'×'99H秋-23'和'苏州青'×'SI'为试材，研究了低温预处理和高温预培养对花药培养效果的影响。

When one young man with a bulging bag jogged up from the beach, Anita Rajendra Udayaar, the keeper of a roadside stall full of recycled plastic bottles, asked where he was heading.

当一名带著大包的年轻男人从海岸方向离开时，路边一个装满旧塑料瓶的小摊的摊主Anita Rajendra Udayaar问他到哪里去。

If you haven't been on a bike for a while, take some time to reacquaint yourself by riding in a controlled environment before heading out onto the streets.

如果你还没有在一段自行车了，需要一些时间才能reacquaint在受控环境中乘坐前往前走上街头自己。

If you haven't been on a bike for a while, take some time to reacquaint yourself by riding in a controlled environment before heading out onto the streets.

如果你没有被租借一段时间了，需要一些时间来reacquaint自己踏在受控环境中，然后驶向走上街头。

If you havent been on a bike for a while, take some time to reacquaint yourself by riding in a controlled environment before heading out onto the streets.

如果您haven 吨一直对自行车了一会儿，需要一段时间才能reacquaint自己骑在一个控制的环境中的标题出来之前，走上街头。

This technique promotes carbon remobilization from culms and sheaths to grains and NSC(non-structural carbohydrate) residue in the stems at heading stage increased,and the reversed result was observed at the maturity stage.

有关水稻氮肥利用的研究多偏重于单项研究。引进的国际水稻所的实地氮肥管理技术在浙江、江苏、湖南、广东、湖北和黑龙江等省示范推广，取得了明显节氮增产的效果[4，5]。

The critical nitrogen content in heading period was used to calculate the biggest accumulation quantity of nitrogen. The latent distribution index of leaf and stem, which was the variety heredity parameter, were used to distinguish the difference in nitrogen assignment in different varieties. The dynamic content of the nitrogen accumulation before anthesis could be described with a Richards model. The dynamic content of the nitrogen remobilization in leaf with leaf area index could be described with a power model, and the nitrogen absorption of grain from soil with dry weight could be described with a power model. The dynamic content of nitrogen density in stem and spike with physiological development time could be described with a nonlinear model.

模型利用抽穗期植株临界含氮量来表达氮素最大积累量，引入叶片潜在分配指数和茎鞘潜在分配指数2个品种遗传参数来区别不同品种在器官间的氮素分配差异，采用Richards方程来描述大麦花前氮素积累动态变化；采用指数函数方程来描述叶片氮的转移量随叶面积指数的动态变化以及籽粒从土壤中吸收的氮量随干物重的动态变化；采用非线性函数方程描述茎鞘和穗部的氮浓度随生理发育时间的动态变化。

At last, I'm so touched and more proud. Because there are no top leaders who can run to the locales immediately during the continous strong aftereffect earthquakes like ours in other big countries. They are heading the resue work at the first moment and standing by the victims to share the suffering together.

最后，我很感动，也更骄傲，因为没有哪个国家的最高领导人们，能像我们中国的领导人这样，面对如此巨大的灾难，频频不断的余震，时时尚存的险情，在第一时间，毅然亲赴前线指挥营救，与人民站在一起共患难。
