简介：从不肥沃的夫妇的28个男搭挡镇定的精液样品被划分成三相等的aliquots并且与三准备了选择媒介，例如PureSperm吗？(Nidacon，Gothenburg，瑞典)，Sil选择加？(Fertipro，Beernem，比利时)并且SpermGrad？(Vitrolife，Gothenburg，瑞典)。在精液参数的吝啬的百分比的差别被重复措施分析估计。精子DNA的关联损坏刻痕结束标记，由终端deoxynucleotidyltransferasedUTP测量了(TUNEL)试金，并且鱼精朊缺乏测量了由与精子参数染色的chromomycinA3(CMA3)，被皮尔森的关联决定。在有所有三媒介的准备以后，精子集中减少了(P<0.05)当有正常形态学的精子的百分比增加了时(P<0.05)。精子活动性，快速的活动性和进步能动集中(PMC)的百分比增加了(P<0.05)为每这些参数，PureSperm准备给了最好的结果(P<0.05)。DNA损坏的百分比在PureSperm和Sil选择正准备减少了(17.9%和31.3%，分别地P<0.05)并且在SpermGrad准备增加了(56.3%，P<0.05)。鱼精朊缺乏也在所有三种媒介减少了，59.3%，47.7%和40.3%为PureSperm，Sil选择加和SpermGrad准备，分别地(P<0.05)。损坏DNA的精子的百分比否定地与精子活动性，快速的活动性和PMC的百分比被相关，但是断然与静态的活动性被相关(P<0.05)。这比较学习和关联分析表明PureSperm准备与最好的活动性和鱼精朊缺乏的最低百分比产出精子。Sil选择正准备与DNA损坏的最低数量产出精子。SpermGrad准备与正常形态学有精子的一个高百分比，而且与DNA损坏有精子的最高的百分比。精子DNA损坏与精子活动性，快速的活动性，静态的活动性和PMC的百分比被相关。

简介：三次积极的碳同位素旅行在Tahe油气体地里从中间上面的奥陶纪被报导，北Tarim盆。把biostratigraphy，中间的Darriwilian同位素碳旅行(MDICE)和Guttenberg碳同位素旅行(GICE)基于conodont被整个岩石的碳同位素数据的帮助从二个井核心从Darriwilian识别到早Katian。在conodontPygodusanserinus地区以内的积极旅行在早Sandbian被开发，并且变化范围是不亚于MDICE。因为在概括的全球碳同位素曲线的这次旅行的范围是短的，以前的研究几乎没对它给予注意，并且在这份报纸把早Sandbian称为同位素碳旅行(ESICE)。而且，这些积极旅行直接没在北Tarim与海水平变化和MDICE和GICE有关被识别能全球性在南部的中国，北美洲，南美洲，和欧洲被相关到那。SaerganFm。在KalpinDawangou露头的中间上面的奥陶纪的来源岩石与MDICE的地质的时间一致，ESICE，和GICE有强壮的关系到LianglitagFm的来源岩石。在盆。丰富的器官的碳埋葬是在积极同位素碳旅行的开始的一个重要因素。沉积外形的积极的氧同位素旅行，conodont动物志周转，减少的conodont总数差异，和变化显示在Tarim盆的早中间的奥陶纪的paleoceanographic环境的戏剧的变化近来从Darriwillian，和明显的冰库气候的结束开始了奥陶纪发生在ESICE。
