2,500-year-old
1.In the process the 2,500-year-old brick pavement to the Ishtar Gate was smashed by tanks and the gate itself damaged.
2.To investigate the effect of high-pressure processing technology on the tenderness of cattle muscle, four simmental bulls of 2-3 year-old, 500kg gross weight were chosen ramdomly. Semitendinosus was treated respectively by high-pressure at 100, 200 and 300MPa for 2, 6 and 10min after slaughter.
3.The sustainable management technology for D. oldhami is(1) during later middle shooting stage,keeping 2 or 3 new culms per clump i.e.making the culm age structure of clump as 1 year old∶2 year old=2∶1, (2)chopping their top in next early spring and keeping the culms with 7 internode height,which will give 160 500 sub branches·hm -2 sustainablely in each year.
