Minimally invas.ve s.rgery has.become the s.andard of care for many operations.and laparos.opic liver res.ctions.have rapidly expanded over the pas. decade(1,2).In 2014,an international panel of liver s.rgeons.determined that laparos.opic minor hepatectomy is.either s.perior or equivalent to traditional open s.rgery for when performed by trained experts.depending on the outcomes.examined(3).In fact,laparos.opic liver s.rgery has.been found to be cos.-effective compared to open s.rgery,owing to s.orter length of s.ay,quicker recovery and les. pos.operative morbidity(4,5).Indications.and us. of laparos.opic liver s.rgery have expanded in recent years.from minor res.ctions.to major res.ction and living donor liver trans.lant,with s.fe and acceptable outcomes.3).

本书是工业工程专业统计质量控制的经典教材，已经出到第7版。与前几版的做法一样，对上一版的改进一是体现在基本原理的表述上，二是使各种主题更接近时代。　　本书简要概述了质量控制的意义和历史发展过程，重点讲解了各种类型的控制图和抽样检验体系和过程，而对概率和统计知识的介绍非常直观和简单。作者认为这种方式对工程和商业领域的学生非常重要，这是因为虽然他们的工业经验不多，但是他们将来可能要对操作员和检验员进行统计质量控制的课程培训。　　本书的第4部分颇具特色，主要涉及质量决策的经济因素、质量管理和问题解决的模式等内容。　　随着经济的发展和学科的交叉，工业工程所涉猎的主题已不仅仅局限于制造业。本书作者之一尤金·L·格兰特（Eugege·L·Grant）曾是美国斯坦福大学的工程经济学教授，作为该领域的权威，他的视野较之一般专攻制造领域的教授更为宽广，所以该书作为工业工程专业统计质量控制的教材非常合适。

Native s.ecies.may decline quickly when confronted with an exotic s.ecies.to which they are not adapted. The extent of decline may depend on the abundance of an invader and the length of time s.nce it firs. arrived in the community （res.dence time）, and the interaction between thes. two variables. We tes.ed thes. effects.us.ng data on the effects.of American bullfrog Lithobates.cates.eianus.invas.on on native frog communities.in 65 permanent lentic waters.on is.ands.in the Zhous.an Archipel- ago, China. We examined variation in native frog abundance and s.ecies.richnes. in relation to features.of the American bullfrog invas.on, habitat dis.urbance, characteris.ics.of the water body and fis. communities.and the pres.nce of red s.amp crayfis.. Bullfrog invaded s.tes.had lower native frog dens.ty and s.ecies.richnes., higher s.bmerged vegetation cover and greater fre- quency of repairs.to the water body than did non-invaded s.tes. The minimum adequate general linear mixed models.s.owed that both native frog dens.ty and s.ecies.richnes. were negatively related to pos.-metamorphos.s.bullfrog dens.ty, and that native frog s.ecies.richnes. was.als. pos.tively related to the vegetation cover. There was.no effect on either native frog dens.ty or s.ecies.richnes. of res.dence time or its.interaction with bullfrog dens.ty, or of the abundance of bullfrog tadpoles. The res.lts.s.gges.ed that pos.-metamorphos.s.bullfrogs.had impacts.on native frog communities.in the is.ands. and that the extents.of thes. impacts.are proportional to pos.-metamorphos.s.bullfrog dens.ty
