The paper summarized the research for the effects of different grazing intensity on grazing behaviour , grazing grass species and productivity of sheep in recent years , the result showed that : there was a negative correlation between the live weight gain per sheep and the grazing intensity , but there was positive correlation between the live weight gain per hectare and the grazing intensity ; feeding intake of sheep decreased when the grazing intensity become heavier ; there was not significant effect of different grazing intensity on sheep breeding indexes ; as long with the grazing intensity become heavier , the feeding time of sheep increased while resting and idling time decreased , but feeding intake per hundred mouths and daily intake reduced while intake velocity increased ; sheep feeding adaptability is relative ; the light grazing was beneficial to promote mutton quality , but mutton quantity and gross economy benefit was low 摘要根据近几十年来放牧强度对绵羊放牧行为、采食植物组成和生产性能的影响进行了综述，得出以下结论：绵羊的个体增重与放牧率之间呈线性负相关，而公顷增重与放牧率之间呈正相关；绵羊的采食量随著放牧强度的加重而降低；放牧强度对母羊繁殖性能各指标影响差异不显著；随著放牧强度的加重，绵羊的采食时间增加，游走、反刍卧息时间减少；每百口采食量和日采食量减少，而采食速度增加；放牧绵羊的嗜食性是相对的；轻牧有利于提高肉的品质，但是产肉量低，总的经济效益不高。
No . 324 ( fuzhou - kunming ) national highway and silian highway ( sihui - lianzhou ) , which joint up the guangmao ( guangzhou - maoming ) railway and the xijiang , suijiang watercourses , traverse the whole city , now the city has got a total highway mileage of 5602 km and on average there are 38 . 3 km of highway in every sq 公路国道321线（广州至成都） 、 324线（福州至昆明） 、四连线（四会至连县）纵横全境，与广（州）茂（名）铁路和西江、绥江水道交汇。全市公路总里程5602公里，公路密度为每百平方公里38 . 3公里。
This paper introduces the none - defect operation method of high - grade knitting yarn manufacturers , which eliminated the lapped joints of the yarn from drawing , roving upto spinning , reduced defects , remarkably raised the roving efficiency and minimized the yarn breakage per 1000 spindles in spinning and the yarn breakage per 100 bobbins in cone winding 摘要高档针织用纱企业推行的无疵点操作法，从前纺并条、粗纱到细纱取消了原来的包卷接头，减少了长粗、长细纱疵的产生，粗纱效率明显提高，细纱每千锭时断头和络筒每百管断头下降。
Based on the sha lo wan profiler data at 0740utc , the vertical shear at around 1 , 100 ft was close to 8 kt per 100 ft . although this was lower than the 8 kt per 100 ft which has been used in the windshear warning system at the old kai tak airport , the increase in head wind was nonetheless significant due to the steep climb angle 根据沙螺湾的气流剖析仪在0740utc录得的资料显示，在约1 , 100尺的垂直切变接近每百尺每小时8海里。虽然此切变低于以往启德机场的风切变警报系统所用的每百尺每小时8海里，但因为陡峭的爬升角度，令到逆风的增加变得显著。
