光周期的

In addition, through analysis the solution of the Einstein Field Equation in static spherical symmetry gravitation field, we get the relationship between proper time and coordinate time ,as well as the rate of light signal period, with which the rate of frequency can be calculated.

文章通过对静态球对称引力场中的爱因斯坦场方程的解的分析，得出了标准时和坐标时的关系，利用这个关系求得一个光信号的周期之比，从而求得频率之比。

With this method, we had several important differences compared to the YDmodel. First, the ratio of daily increment of PDT and the deficit of both water and nitrogen was used to estimate the effect of environment. Second, a nonlinear function was adopted to describe vernalization and thermal effectiveness (instead of three-stage linear function). Third, sinusoidal function was used to describe photoperiod curve cluster for different cultivars.

本模型在YDmodel基础上的改进主要有3点：（1）将每日生理发育时间的增量乘以水肥丰缺因子，改为除以水肥丰缺因子表现水肥对大麦发育的影响，客观体现了大麦在水肥丰缺条件下的发育延迟或提早现象；（2）将三段线性函数改为非线性函数表达春化效应和相对热效应，确立了不同品种相对春化效应和相对热效应的曲线族；（3）将线性函数改为正弦函数表达不同品种光周期效应。

The homeotic gene not only plays a role in the tegulation of cell ar- rangement in plant s organ, but also is the base of the floral meristem identity, inflores- cence meristem identity and floral organ identity.

植物由营养状态转入生殖状态是发育过程中的重要一步，其转变过程受遗传固子及环境的双重控制，光周期与温度是影响开花诱导的主要环境固子，而植物的同源异型基因参与植物器官内细胞排列方式形成的调拉过程，是拉制花分生组织特异性、花序分生组织特异性和花器官特异性的基础。

Their actions and interactions may adjust the phasic development of wheat to avoid environmental stress.

春化反应、光周期反应和早熟性本身是影响小麦抽穗期的三种重要因素，它们的作用和互作可以调节生育期以应付不同的环境胁迫。

The hormonal balance , especially the ratio of GA to ABA, played important roles in photoperiodic responses of soybean.

促进激素与抑制激素含量的同趋势消长维持体内激素水平的相对平衡，两类激素，特别是GA和ABA的平衡状况在大豆光周期反应中起重要作用。

The black spots ocurred in the fore wings of male were under photoperiodic control.

雄虫前翅黑斑的出现是由光周期控制的，只有在短日照下诱导的滞育蛹，滞育解除后羽化出来的雄虫才会出现黑斑。

Many pathways regulated the flowering transition including circadian clock associated genes such as GI and CO which play a mediated role in photoperiodic pathway of Arabidopsis.

植物由营养生长到生殖生长的过程中，受到许多途径的调节，而光周期途径中的CONSTANS基因扮演关键的角色。

I investigated diel and seasonal patterns of sound production in captive grey gurnards subject to natural variations in water temperature and photoperiod.I also examined daily variations in activity.

Different photoperiods:⑴ Long-day treatment accelerated the process of flower bud differentiation and increased the numbers of the flower buds of two-crop cultivar; short-day treatment accelerated the process of flower bud differentiation of one-crop cultivar, but long-day treatment increased the numbers of the flower buds per inflorescence.

不同光周期下：⑴长日照促进二次花品种的花芽分化进程和单花序上花芽数量的增加；短日照加速了一次花品种植株花芽分化进程，而长日照促进了其单花序上花芽数目的增加。

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。
