| 1. | Low activity waste
低放废物 |
| 2. | You should also try to avoid migrating during a scheduled vacuuming interval , which often occurs during periods of low activity
还应尽量避免在计划的数据清除时段进行迁移，此时段往往是在低活动期间。 |
| 3. | You should also try to avoid upgrading during a scheduled vacuuming interval , which often occurs during periods of low activity
还应该尽量避免在计划的删除间隔期间升级，删除间隔通常出现在活动不频繁的时侯。 |
| 4. | Migrate instances during periods of low activity to minimize the impact on event collection , notification generation and distribution , and subscription management
请在低活动期间迁移实例，以尽量减少对事件收集、通知生成与分发以及订阅管理的影响。 |
| 5. | Upgrade instances during periods of low activity to minimize the impact on event collection , notification generation and distribution , and subscription management
请在活动不频繁的时侯升级实例，以便尽量减少对收集事件、生成和分发通知以及管理订阅的影响。 |
| 6. | Because locks prevent other users from updating the tables , the snapshot agent should be scheduled to execute during periods of lower activity on the database , especially for snapshot publications
由于锁会阻止其他用户更新表，所以应把快照代理安排在数据库活动较少的期间执行，对快照发布尤其如此。 |
| 7. | Although the sql server 2005 database engine can back up a database while it is being used , schedule the backup process to occur during times of low activity to minimize the effects on users
尽管sql server 2005数据库引擎可以在数据库正在使用时对其进行备份，但是应将备份过程安排在活动不频繁时进行，以使对用户的影响减至最小。 |
| 8. | Be aware that producing a snapshot can be resource - intensive , so it is best to generate snapshots during periods of lower activity on the database by default a snapshot is generated when you complete the new publication wizard
请注意，生成快照可能占用大量资源，因此最好在数据库活动较少的期间生成快照（默认情况下完成新建发布向导后就生成快照） 。 |
| 9. | There is a distinct relationship between children ' s temperament and self - delay of gratification , the characteristics of well - developed children ' s temperament on self - delay of retardation are low activity , active emotion , persistence and low impulsive

| 10. | Rlean meat percentage is one of the most important economic traints in pig breeding programs . myostatin is a negative regulator of skeletal muscle growth . null or low activity of myostatin , individual muscle of mutant amimals would show a large and widespread increase in skeletal mass . myostatin null animals have significantly larger diameter or more quantity of fiber skeletal muscle . the phenotype was termed double muscling . in order to probe the relation between myostatin and high lean meat rate and plump - hipped trait , we sythesized the c ' 80 amino acids coding sequence of porcine myostatin and costructed the cloning and expressing vector of it
肌生成抑制素( myostatin ，即mstn )是近几年来( mcpherrona . c等， 1997 )发现的骨骼肌生长的负调控因子，它主要在骨骼肌中表达。其活性的丧失，会引起动物肌肉的过度发育，肌纤维直径变大或肌纤维数增加，表现为双肌症状。肌生成抑制素研究的突破将对猪、肉鸡、肉牛等畜禽生产性能的提高具有特别重要的意义。 |
