Zero once the damaged track will be the primary boot hard drive and the partition table information will be seriously damaged, resulting in the hard disk can not boot. 0 tracks damaged judge: System self-test pass, but the boot partition C disc lost or directory is missing, there are laws of the hard disk "... creak ... creak" seek the sound of running SCANDISK scanning C disk, in the first cluster a red "B", or can not find Fdisk the hard disk, DM died in the 0 track, the track such a situation that is zero damage!

零磁道一旦受损，将使硬盘的主引导程序和分区表信息将遭到严重破坏，从而导致硬盘无法引导。0磁道损坏判断：系统自检能通过，但启动时，分区丢失或者C盘目录丢失，硬盘出现有规律的"咯吱……咯吱"的寻道声，运行SCANDISK扫描C盘，在第一簇出现一个红色的"B"，或者Fdisk找不到硬盘、DM死在0磁道上，此种情况即为零磁道损坏！

Methods With a questionnaire, a stratified cluster sample of 7 527 students were investigated. Multivariate logistic regression analysis was performed to assess factors for suicidal ideation.

方法采用统一调查表，应用分层整群抽样的方法调查广州市8所中学和8所小学学生7 527名，通过多因素Logistic回归模型筛选自杀意念的危险因素。

An astronomer can examinea galaxy and from its brightness make a guess as to how many stars and how much dusty gas it contains. Yet when we track the movements of galaxies in a self-contained cluster, they move as if galaxy were far heavier than it appear. It's like watching go-carts move as unstoppably as trucks.

尽管天文学家能够对某个星系进行观察并根据其亮度推测它所含恒星的数量和尘埃气体的多少，但是当我们把众多星系作为一个独立存在的整体来观察其运动时就会发现，每个星系运动起来似乎比我们所看到的要重得多，这就像我们看一辆儿童手推车以卡车般巨大、难以阻挡的惯性向前奔驰一样。

Via comprehensive computations, the possibilities of vinylidene and allene intermediates were excluded, and the reaction mechanism was found to contain the following three steps:(1) gold-catalyzed cyclization to give the cyclic intermediate,(2) the cyclic intermediate undergoing a 1,3-H migration to give a more stable intermediate, with the assistance of water-cluster,(3) finially, the 1,2-H or 1,2-silyl migration occuring for generation of the observed product.

通过对各种可能的反应路径的进行计算和比较，排除了亚甲基卡宾和连二烯中间体的可能性，并确定该异构化反应机理包含以下三个步骤：（1）炔丙基吡啶反应在金催化条件下发生分子内的成环得到环状中间体；（2）环状中间体在水分子簇的协助下优先发生1，3-氢迁移反应，异构化得到更为稳定的中间体；（3）最后再进行1，2-氢迁移或是1，2-硅烷基团迁移即得到实验中所观察到的环异构化产物。
