下列关于油气分离的叙述中错误的是()。
A

一次脱气即接触分离,即在油气分离过程中分离出的气体与油始终保持接触,体系的组成不变

B

多级脱气即差异分离,即在脱气过程中将每一级脱出的气体排走后,液相再进入下一级,亦即脱气是在系统组成变化的条件下进行的

C

通常一次脱气比多级脱气分离出的气量多,而油量少,即测出的气油比高

D

脱气方式不同,从油中分离出的天然气量不同,一般以多级脱气测定的溶解气油比为准

Passage1Children who spend more than two hours a day at a computer or watching television are more likely than others to have mental problems,scientists say.Researchers found that 11-year-olds who spent several hours in front of a screen each day did worse on mental health tests,no matter how much physical exercise they got. The University of Bristol study,published in Pediatrics,involved more than 1,000 children aged about 10.They also had the kids fill out questionnaires designed to gauge the kids' emotional well-being and behavior.The questionnaires contained 20 questions covering five sections-emotional difficulties,conduct problems,hyperactivity or inattention,friendships and peer groups and problems relating to friends and peer groups.The study found no direct evidence that sitting in front of a screen actually causes mental health problems. Instead,it suggests that children with difficulties,such as extreme shyness,are more likely to choose TV or computer games than sociable activities. In the study,children were asked whether they agreed,disagreed or somewhat agree with a list of statements,including,"I generally play alone or keep to myself" and,"I am often unhappy or tearful".They were also asked how much exercise they took and how long they spent at a TV or computer screen.According to the study,children who spent more than two hours a day at a screen had a 60% higher risk of mental problems than children who spent fewer viewing hours. The risk was only slightly higher in children who did little or no exercise."Physical activity is good for health in many ways,but it can't make up for long hours of screen viewing. Parents should consider limiting their children's screen viewing to no more than 2 hours a day,”said the study organizer,Angie Page.Previous studies have raised concerns that watching too much television can affect children's behavior in later life. A Canadian study found that those who watched most TV as young children performed worse at school, ate more junk food and had more trouble concentrating.What information can we get about the University of Bristol study?
