查询词典 a grain of

This paper mainly examined the longterm variations in the grain size of bottom sediments since the 1950s at Datong, the landward limit of the Yangtze Estuary.

The 0°K relaxed structures of grain boundaries in Cu and its alloys (Cu-Ag, Cu-Bi) were simulated with molecular dynamics method by using a five-parameter potential and constant volume assumption.In these cases, the results showed that the atomic distribution was periodic in the two directions paralled to the grain boundary and it was mirror-symmetric in the direction perpendicular to the boundary.

The objective of this study was to understand the content of B vitamins (thiamine, riboflavin and pyridoxine) in colored grain wheat, and their Patterns of variation, and provide a theoretical basis for optimization of B vitamins content in wheat breeding.

小麦籽粒含有多种B族维生素，本研究通过测定24个不同粒色的小麦品种中维生素B1、维生素B2、维生素B6及籽粒色素含量，并研究不同颜色的小麦籽粒中B族维生素含量与小麦籽粒颜色的关系及其变异规律，为B族维生素的利用及小麦品质育种提供依据。

Completion of the project, together with those in 2008 before the implementation of the reconstruction project, Bayannur City Hetao irrigation area of 787 hectares of existing irrigation Yellow fundamental transformation will be completed, can add 50 million mu of cultivated area ; Yellow River Irrigation District water will be reduced by 1.2 billion cubic meters, equivalent to savings of 12 large reservoirs (according to the criteria for the classification reservoir, storage capacity up to 100 million cubic meters is large reservoirs); the annual grain production capacity can add three billion kg, close to irrigation district The current annual production of 3.8 billion kg of grain, and create a "granary north of the Great Wall."
