查询词典 LAI

On the basis of sensitivity analyses using the PROSAIL model, the present study demonstrates an approach that uses a neural network based on image classification incorporated in PROSAIL for accurate retrieval of LAI. By including the soil reflectance index in the original PROSAIL model to take the place of soil background reflectance parameters that are difficult to determine, specific neural networks are constructed corresponding to individual types of vegetation cover.

在PROSAIL模型敏感性分析的基础上提出了一种基于影像分类的神经网络反演方法，引进了土壤反射指数用于替代原模型中难以确定的土壤背景反射参数，分别针对不同植被类型建立各自的神经网络，对经过大气纠正后的Landsat ETM+影像进行了模拟实验并同野外实测LAI数据进行比较。

Diu lai no mo hai, far as I'm concerned.

Diu lai no mo hai，这是我能关注到的。

Fuhua 4 has moderate amount of flowers, centralized flowering season and high effective flower rate. LAI of the seedling stage and pod setting stage lower than the control, and the etceteras high compared to the control. The NAR of Seedling stage, bearing pod stage and yield-forming stage is higher than the control.

福花4号花量适中，花期较集中，有效花率高；幼苗期和饱果成熟期的LAI比对照低，其余时期比对照高，苗期，结荚期这两个与产量形成重要时期比对照有较高的净同化率。

Their seasonal variations were related with vegetation characteristics such as leaf area index and canopy height as well as wind speed.d had a close linear relationship with h,and the variations of Z0 with h could be expressed by quadric curves.d/h and Z0/h were nearly correlated with LAI,and multiple correlation coefficient could be 0.99 and 0.78,respectively.

芦苇湿地的Z0和d的季节变化主要受叶面积指数、株高及风速的影响。d随h的增加而单调增加，Z0随着h的变化遵循二次曲线，d/h、Z0/h与LAI之间的复相关系数分别为0.99和0.78。

"Learning more about the way a specific type of cancer deelops, and what proteins it produces as it grows, helps us find better ways to treat that cancer," said Dr. Lai, who is a cancer researcher at Mayo Clinic with background as an otolaryngologist."With nasopharyngeal cancer, we think this new enzyme may help sole the puzzle."

"了解更多的有关特定肿瘤发育过程的知识，以及其生长过程中产生的蛋白质，能够帮助我们找到更好的治疗肿瘤的办法，"具有耳鼻喉科医师身份，目前作为肿瘤科研人员工作在Mayo临床中心工作的Lai博士说："对于鼻咽癌，我们认为这种新的酶能够解决这些难题。"

We extend Frankel (1986) and Lai、Hu and Wang (1996) models, where using target zone policy and simultaneous stochastic differential equation methods, to investigate whether the honeymoon effect proposed by Krugman (1991) is present when the government adopts a target zone policy on agricultural prices.

我们将延伸Frankel(1986)及Lai、Hu与Wang(1996)分析农产品市场的概，配合目标区政策及随机微分方程之方法，探讨当农产品及非农产品价格皆可瞬时调整时；政府宣告目标区政策，民众的预期将如何影响农产品价格及其他经济变之稳定性。

The correlation between yield and canopy structure indices was the closest during the middle stage of fruiting, then during the latter stage of fruiting, and was the smallest during the seedling stage. It was beneficial to yield formation of summer squash to retain stable and higher canopy height, bigger LAI and lower leaf area density.

产量与结果中期的冠层结构指标相关性最大，其次是结果后期，与苗期相关性最小，结果期维持较高较稳的冠层高度、叶面积指数(leaf area index ，LAI)，较低的叶面积密度，有利于西葫芦产量的形成。

"From our perspective, that's good," says Mr Lai.

Michael Lai表示：从我们的角度看，这很好。

His father is 53 year-old lai Switzerland.

他的父亲是53岁的lai瑞士。

However, currently, the retrieval of multiangular remote sensing seldom considers the use of spectral information. We use MSAVI2 as an index to get the a priori knowledge of LAI. As a result, the a priori knowledge is more objective. From the comparison of using or not using this MSAVI predicted a priori knowledge, we found that this approach is effective.

与以往的反演方法相区别，该文利用行播作物二向反射模型，将多角度与多光谱数据结合进行行播作物LAI反演实验，并对反演算法进行了详细的敏感性分析实验，结果表明采用多角度、多光谱遥感数据相结合的方法可以有效反演行播作物的叶面积指数。

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。
