| 4. | Description : large evergreen trees to 30 m tall and 1 m in dbh ; twigs glabrous except grayish puberulous on nodes when young 形态特徵:常绿大乔木,高15 - 30米,胸径可达1米;小枝无毛,但嫩时芽及节上被灰褐色、平伏的微柔毛。 |
| 5. | However the density of trees increased , and at the same time , shrubs density , maxium proportion of tree number of certain dbh range trend to decrease 而乔木密度呈增加趋势,而灌木密度和乔木树种的最大株数比例的胸径范围呈不断降低趋势。 |
| 6. | A good number of saplings and middle - sized piants were found and most of them were individuals of dbh ranging from 2 to 4 cm . the number of old individuals were relatively small 幼树和中等大小个体的数量较多,且绝大部分集中在2 4cm径级,老龄个体较少,属增长型种群。 |
| 7. | 4 , the diameters at tree breast height ( dbh ) of trees that birds feed on change significantly for 12 years fore - and - aft ( p < 0 . 01 ) , which is consistent with the significant changes ( p < 0 . 01 ) of dbh in habitat 鸟类取食树种的胸径在12年前后变化显著( p 0 。 01 ) ,这一特点与其生境树种的胸径变化显著( p 0 . 01 )是一致的。 |
| 8. | If you open the connection at the top of your main script and store the handle in a global variable , then the connection will remain open until your script ends , or until you set the the dbh variable to null 如果在主脚本的顶端打开连接,并将其句柄存储在一个全局变量中,那么该连接将一直处于开放状态,直到脚本结束,或者直到$ dbh变量被设为null 。 |
