territory either time and lost his life on the re. mm voyage to England after
the second attempt. Raleigh, in turn, was granted the right to settle in

any colonists to the new continent. The first landed on the island of Roanoke

anything but enthusiastic about their new home, these first colonists returned

A.击实曲线一般有个峰点，这说明在一定击实功作用下，只有当土的含水率为某一定值（最佳含水率）时，土才能击实至最大干密度。若土的含水率小于或大于最佳含水率时，则所得到的干密度都小于最大值 B.当土的含水率偏干时，含水率的变化对干密度的影响要比含水率偏湿时的影响更为明显，一般曲线的左段较右段陡 C.《公路土工试验规程》中含水率与干密度曲线右侧的一根曲线成为饱和曲线，它表示当土在饱和状态时的含水率与干密度之间的关系，饱和曲线与击实曲线永远不相交 D.增加击实功就能将士中气体全部排出，击实曲线就能与饱和曲线相交 [单项选择]抗风湿治疗，选用肾上腺糖皮质激素的指征是（）
