通过标本检查，发现小五台银莲花(Anemone xiaowutaishanica W. T. Wang&Bing Liu)与银莲花(A. cathayensis Kitag. ex Ziman&Kadota)属于同一种植物，故将前者处理为后者的异名。由于银莲花属于银莲花亚组[subsection Omalocarpus (DC.) Tamura]，故同时将根据小五台银莲花而建立的小五台银莲花组(section Leptothece W. T. Wang&Bing Liu)处理为银莲花亚组的异名。
Examination of herbarium specimens has shown that Anemone xiaowutaishanica W. T. Wang&Bing Liu is conspecific with A. cathayensis Kitag. ex Ziman & Kadota. We therefore place A. xiaowutaishanica in synonymy under A. cathayensis. As A. cathayensis belongs to subsection Omalocarpus (DC.) Tamura, we place section Leptothece W. T. Wang&Bing Liu, which was established based on A. xiaowutaishanica, in synonymy under subsection Omalocarpus.

DSP/BIOS是TMS320F28xxx系列DSP上的一个实时操作系统内核。由于TMS320F28335内部FLASH性能的限制，当DSP/BIOS系统直接在芯片内FLASH上运行时，程序运行的速度往往比在RAM上运行时慢得多，严重影响了DSP/BI?OS的实时性。为了解决这个问题，通过分析TMS320F28335的启动过程和程序从FLASH搬移到RAM上运行的一般流程，以及DSP/BIOS与非DSP/BIOS工程的Memory Sections特点，提出一种通过在c_int00之前增加Copy_Sections等一系列操作对DSP/BIOS系统及用户程序进行搬移的方法。由此实现在芯片启动后自动把DSP/BIOS系统从片内FLASH搬移到RAM上运行的功能，从而提高DSP/BIOS系统的运行效率和实时性。该方法已经通过实验验证并在实际的工程项目中应用，获得良好的效果，因此值得推广。
DSP/BIOS is a Real?time operating system kernel on DSP of TMS320F28xxx series. When DSP/BIOS system runs directly in the on?chip FLASH,the DSP/BIOS system would be much slower than it runs in RAM because of the perfor?mance limitation of FLASH in TMS320F28335,which affects the DSP/BIOS’s real?time performance seriously. To solve the problem,By analyzing the start?up procedure of TMS320F28335 and the procedure of moving a program from FLASH to RAM, and the Memory Sections features of DSP/BIOS and none DSP/BIOS,a method to add a function named Copy_Sections before c_int00 to copy DSP/BIOS system and user program from FLASH to RAM is proposed in this paper. By doing this,the Function that DSP/BIOS system is automatically copied from on?chip FLASH to RAM after reset or power on the DSP is realized,which improves the efficiency of DSP/BIOS system and its real?time performance. This method was validated by experiment and used in practical project.

We obtain the Omori-Yau maximum principle on complete properly immersed submanifolds with the mean curvature satisfying certain condition in complete Riemannian manifolds whose radial sectional curvature satisfies some decay condition,which generalizes our previous results in [17].Using this generalized maximum principle,we give an estimate on the mean curvature of properly immersed submanifolds in Hn ×Rt with the image under the projection on Hncontained in a horoball and the corresponding situation in hyperbolic space.We also give other applications of the generalized maximum principle.
