查询词典 contraction

RESULTS: Basilar artery, thoracic aorta and ventricular papillary muscle Resting tension of basilar artery was increased by DL but decreased by niof basilar artery and thoracic aorta induced by noradrenaline bitartrate and KCl can be relaxed by DL in a dose dependant manner, and the half-effective concentration was (6.69±3.12)×10-4,(3.41±1.52)×10-3mmol/L for basilar artery, and (1.49±0.59)×10-3,(2.91±0.99)×10-3 mmol/L for thoracic aorta, displaying stronger inhibition on the constriction of basilar artery induced by noradrenaline bitartrate than on the contraction induced by KCl.

In this paper,Laterite soil adjacent to some stake of the highway in Chenzhou, Hunan section from Xiamen to Chengdu was used to investigate the deformation characteristics and protection methods of the Laterite soil subgrade under the influence of environment factors.Properties like water-holding capacity,capillary rise, coupled heat-moisture transfer and wetting deformation of samples under different compactness were studied through a series of laboratory tests.In addition,by using meteorological data of two consecutive years in Chenzhou,coupled process of moisture transfer and subgrade deformation was stimulated under the impacts of groundwater and the atmosphere.Specific work done in this paper is as follows:(1) Samples under different compactness were subjected to a series of conventional laboratory tests,such as permeability,consolidation,contraction,shear test and etc.
