查询词典 swamp

We found that individual sensorimotor neurons in freely behaving swamp sparrows expressed categorical auditory responses to changes in note duration, a learned feature of their songs, and that the neural response boundary accurately predicted the categorical perceptual boundary measured in field studies of the same sparrow population.

在田野调查纪录期间，他们发现在野外沼泽带鵐学习歌唱时，个体的感觉运动神经对外在变化表现明确的听觉反应，且神经反应的分界可以准确预测绝对感知的分界，此在相同的沼泽带鵐族群中可被侦测到的。

水资源的变化是决定当地植被退化的主导因子，在大面积湖泊、河流背景上是沼泽植被，在干涸湖泊、河床背景上的是盐生草甸植被，在沙质荒漠背景上的是荒漠植被。

逆译法。有些英语长句的表达顺序与汉语表达习惯不同，基本完全相反，这时就必须从后面译起。如

The following conclusions have been made in this paper.(1) Based on CO_2 flux data of eddy covariance, variation characteristics of gross primary productivity in four flux observation stations were studied, which are an alpine meadow, an alpine shrub meadow, a swamp alpine meadow and a steppe alpine meadow at Dongxiong. The results show that photosynthetic capacity of the alpine meadow is the highest, and the annual total GPP is 652.2g C/m~2. Daily-differencing approach is used to analyze the random error of CO_2 fluxes measurements. The results show that the distribution of random error follows more closely follows a double-exponential, rather than a normal distribution, capturing the high peak and thick tail, and the random error varies with environment variables, which violates the assumptions for the ordinary least squares fitting with normality and homoscedasticity, consequently, we introduce maximum likelihood method for parameter optimization.

本文主要在以下几个方面开展工作并获得了一些认知和结论：(1)通过分析样带区域内高寒草甸、高寒灌丛、沼泽化湿地和草原化高寒草甸四个通量观测站点草地生态系统总初级生产力变化特征，研究结果表明HBBT矮嵩草草甸生态系统植被光合作用能力较强，年GPP总量为652.2 gC/m~2，明显高于其他三种生态系统；通过利用"单塔日变化法"获得四站点通量观测数据随机误差，结果表明通量观测随机误差概率分布呈现尖峰厚尾的特征，与正态分布相比，更服从双边指数分布，进一步分析表明通量观测随机误差随环境变量(风速、温度和光合有效辐射)的变化而变化，这违背了普通最小二乘法进行生态过程模型参数优化正态分布且误差同质的假设，因此本研究中引入最大似然法进行生态过程模型参数优化。

Instead of calling on some scholar, I paid many a visit to particular trees, of kinds which are rare in this neighborhood, standing far away in the middle of some pasture, or in the depths of a wood or swamp, or on a hilltop; such as the black birch, of which we have some handsome specimens two feet in diameter; its cousin, the yellow birch, with its loose golden vest, perfumed like the first; the beech, which has so neat a bole and beautifully lichen-painted, perfect in all its details, of which, excepting scattered specimens, I know but one small grove of sizable trees left in the township, supposed by some to have been planted by the pigeons that were once baited with beechnuts near by; it is worth the while to see the silver grain sparkle when you split this wood; the bass; the hornbeam; the Celtis occidentalis, or false elm, of which we have but one well-grown;some taller mast of a pine, a shingle tree, or a more perfect hemlock than usual, standing like a pagoda in the midst of the woods; and many others I could mention.

我并没有去访问哪个学者，我访问了一棵棵树，访问了在附近一带也是稀有的林木，它们或远远地耸立在牧场的中央，或长在森林、沼泽的深处，或在小山的顶上；譬如黑桦木，我就看到一些好标本，直径有两英尺：还有它们的表亲黄桦木，宽弛地穿着金袍，像前述的那种一样地散发香味，又如山毛榉，有这样清洁的树干，美丽地绘着苔藓之色，处处美妙呵，除了一些散在各地的样本，在这乡镇一带，我只知道有一个这样的小小的林子，树身已相当大了，据说还是一些被附近山毛榉的果实吸引来的鸽子播下的种子；当你劈开树木的时候，银色的细粒网闪发光，真值得鉴赏；还有，椴树，角树；还有学名为Celtis occidenta lis的假榆树，那就只有一棵是长得好的；还有，可以作挺拔的桅杆用的高高的松树，以及作木瓦用的树；还有比一般松树更美妙的我们的铁杉，像一座宝塔一样矗立在森林中；还有我能提出的许多别的树。
