查询词典 keeling

In 1955, Keeling devised an instrument that could measure concentrations of carbon dioxide in all kinds of environments, from sooty city rooftops to pristine wilderness forests.

作出这个曲线图的是一位坚持不懈、孤身作战的科学家——查尔斯基林（2）。1955年，基林设计了一台可以用来测量任何环境中的二氧化碳含量的机器，不管是煤烟熏黑的城市屋顶，还是原始蛮荒的森林。

The vanes, which on full-sized boats will be of light wood and fabric construction, will be reversible according to the direction of the wind, reducing the necessity for tacking and avoiding the keeling over common to conventional sailing craft.

A few years later Keeling observed a second cycle: a hemispherical seasonal cycle of CO2, low in summer and peaking in the winter for the same reason CO2 peaks at night: no greens at work to eat it.

几年后基林观察到了二氧化碳的第二个循环特征：二氧化碳的半球形季节循环，浓度在夏天最低，在冬天达到高峰，和二氧化碳的浓度在晚上达到高峰值的原理一样，没有绿叶的光合作用消耗二氧化碳。

Presaging the work of Charles David Keeling, which began two years later, Plass called for new accurate measurements of the increasing CO2 concentration in the atmosphere, which he rightly estimated should be on the order of 0.3 percent per year.

他呼吁科学家对大气中不断增高的CO2浓度进行新的准确测量，并正确地估计出了其增加速度应为每年0.3%，两年之后查尔斯·戴维·基林开始了这项工作。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
