查询词典 tube top

The top of neural tube forms basic encenphalic shape,namely endbrain, interbrain, midbrain and afterbrain. The abnormal closure of neural tube will result in neural tube detects.

胚胎脑发育的早期阶段主要是神经板隆起、弯曲、闭合形成神经管，神经管的头部从前向后依次发育形成脑的基本组织形态，即端脑、间脑、中脑、后脑，在神经管闭合过程中出现异常就会导致NTD。

The results showed that: different concentrations of sucrose and boric acid had significant impact on pollen germination, but different concentrations of calcium had no significant impact on pollen germination. It was most appropriate for tube elongation when sugar 150 gL^(-1) and boric acid 100 gL^(-1). Lack of sucrose would lead to the accumulation of callose in top of pollen tube and hold back its growth. The distribution of callose was regular in pollen tube when the medium lacked boric.

结果表明：蔗糖、硼酸浓度间对花粉萌发有显著影响，钙浓度间对花粉萌发的促进作用不明显；蔗糖150 gL^(-1)、硼酸100 mgL^(-1)时最适宜花粉管伸长；蔗糖的缺乏会导致胼胝质在花粉管顶端积累，使其生长停滞，缺硼时胼胝质在花粉管内分布正常。

By increasing the frame size we raise the bars without radical riser stems and still create balance and proportion with respect to the important knee-to-pedal dynamic. It is important to remember that as frames get larger the top tube effectively shortens. This means that the longer top tube on a larger frame is appropriate because as the bars come "up" and the ratio of saddle to bar drop lessens, the rider achieves a "reach" from the saddle to the handlebars that is just right!

想要看起来像专业骑士，就是这样设定，特色就是低骑姿，计时把般的骑姿可以将更多的体重放到手上，膝盖与踏板的比例强调出力与效率，它能够促使骑士去使用下把位，车架也是建议选择稍小的尺寸，事实上，在90年代登山车顶盛时期与近代的言教报告都把关键点放在空气力学的优势上，所以竞技设定已成为多数单车店使用的方法。
