Notice how this avoids the nested loop structure you wind up coding with os.walk and the callback functions you implement for os.path.walk, making it seem conceptually simpler.

请注意，这样做避免了用os.walk编码时的嵌套循环结构，也避免了为os.path.walk实现的回调函数，概念上更简单。

A preemptive multitasking OS, such as UNIX/Linux, Windows NT/2000 or OS/2, frees up resources when ordered to by the operating system, on a time-slice basis, or a priority basis, so that one application is unable to hog resources when they are needed by another program.

抢先式多任务 OS（例如 UNIX/Linux、Windows NT/2000 或 OS/2）中，操作系统基于时间片或基于优先级命令应用程序释放资源时，应用程序释放资源，以便在其它程序需要资源时，正在使用这些资源的应用程序不会独占它们。

Methods Use the OS specimen of 57 cases of amputation,saw these specimen into spicula of 1cm thick in vertical direction,and make X-ray photograph of multi-spicula,Draw materials in various plane of epiphyseal plate and cartilage ,observe the invasive condition of OS to epiphyseal plate and cartilage under light microscope.

将38例截肢的OS标本，纵向锯成1cm左右的骨片，作多骨片X-线照片，在不同层面骨骺软骨板和关节软骨处多处取材，光学显微镜观察OS对骨骺软骨板和关节软骨侵犯情况。

如果在你的Mac OS X安装在硬盘上不再靴子，你可以启动从Mac OS X安装光盘（按住 C键，同时开机）和运行启动盘的工具菜单。

The os.path submodule to os focuses more on file pathnames. Some of

os 的子模块 os.path 更多用于文件路径名处理。

For Os separation, solvent extraction (Br_2 or CCl_4) and distillation are two mainly effective techniques, and microdistillation is used to further purify Os.

Os的分离纯化方法有蒸馏法和Br2或CCl4萃取法以及微蒸馏法，它们是分离和纯化Os的有效方法，也是目前国内外大多数实验室所采用的方法。

The clock is much slower than real one on the host OS.by searching to Google, I found this post saying about FreeBSD clock is slowing when acting in VMWare as guest OS, and it was also the same reason in Linux that the OS is using APIC to get the clock for the time.

时钟慢得多，比真正的一对东道国os.by搜索到Google ，我发现这个职位说，关於FreeBSD的时钟正在放慢采取行动时，在VMware作为客户操作系统，而且它也是同样的理由认为，在Linux操作系统使用apic得到时钟的时间。

The initial Os and Nd isotopes of high-Ti/Y type picrites are consistent with those of magmatic rocks related to plume, indicating that they were derived from a mantle plume and experienced little contamination with a continental crust and SCLM, therefore, most probably representing Re-Os composition of a primary melt.

木里高Ti／Y型苦橄岩具有高的γOs值以及εNd_(t值，与全球地幔柱成因的岩浆岩石的初始Os同位素比值(γOs=+5～+10)一致，表明它们形成于地幔柱源区，而且它们几乎没有受到地壳或是陆下岩石圈地幔的混染。

For Os measurements, Os ion beams are detected by static multi-ion counting electron multiplier collectors, and the Os memory effect may he eliminated by using 10% HCl-EtOH mixture solution and 10% HCl to clean inlet system alternately.
