Sweat trickles down my back as I traipse through a meadow of tall grass, ironweed, asters—and lots of poison ivy. 我疲惫地走在一片荒烟蔓草中,那里长著紫菀属植物和一大堆野葛。
OBJECTIVE The optimum extraction conditions of shionone from herbs Tatarian aster root were studied by means of orthogonal test and microwave-assisted and pressurized solvent extraction technique. 方法利用微波辅助加压溶剂提取法提取紫菀中紫菀酮,通过正交实验,考察了微波提取条件(包括溶剂、提取时间、提取次数和料液比)对紫菀中紫菀酮的影响。
Through the window-frame the sky looked light by contrast, and above the black mass of asters in the earthen jar one white star glimmered like a moth.
透过窗框,天空显得比较明亮,在瓦罐里那一大团黑色的紫苑上方, 一颗白色的星星像飞蛾一样闪闪发光。
夏
Purple asters and red maple-leaves filled the jar on the table; on a shelf against the wall stood a lamp, the kettle, a little pile of cups and saucers.
紫色的紫苑和红色的枫叶装满了桌上的罐子;靠墙的架子上放着一盏灯、水壶和一小堆杯子和碟子。
夏日走过山间
A good many flowers are still in bloom about the base of the peak, and even on the roof among the little pines, especially a woody yellow-flowered eriogonum and a handsome aster.
Like the rye-field, I found the so-called desert of Mono blooming in a high state of natural cultivation with the wild rose, cherry, aster, and the delicate abronia; also innumerable gilias, phloxes, poppies, and bush-compositae.
On the borders of little streams larger plants flourish — lupines, daisies, asters, goldenrods, hairbell, mountain columbine, potentilla, astragalus and a few gentians; with charming heathworts — bryanthus, cassiope, kalmia, vaccinium in boulder-fringing rings or bank covers.
