简介：大家都知道，RedHat一般6～8个月就推出一个新版本的Linux发行版，然而RedHat谜们等待了N个月都没有等到期待已久的RedHatLinux10。不过心细的朋友可能会发现，RedHat2003年11月6日就在其网站上提供一个名为Fedora的Linux发行版（代号为Yarrow)的下载(http：／／fedora．redhat．com／download)。那么这个Fedora究竟和

简介：为了与僵硬学习负担转移机制和混合堆积的适用的能力，核心(MPSC)被插入预制增强的具体堆积(PRCP)形成，在原处测试与不同长度，直径，水水泥比率和PRCP包含MPSC，水泥混合了堆积，并且钻洞堆积，被执行。限制适用的能力，负担解决曲线和MPSC的压力分发，混合堆积被获得。在水泥土壤和PRCP之间的负担转移被有限元素方法分析(女性)。测试结果和女性的分析证明MPSC充分从从外部顶装进转移内部水泥的PRCP的混合堆积和高压缩强度玷污的水泥利用了大磨擦，并且那插入进混合堆积的PRCP改变混合堆积的压力分发并且改进在混合堆积和土壤之间的摩擦抵抗。长度和MPSC的节区域onPRCP两个都有最佳价值。采用MPSC在改进软土壤地面的适用的能力是有效的。

简介：笔者近日安装了FedoraCore4，初次体验感觉比以前的版本有了很大的提高．尤其在中文设置与易用性方面．但在上网时感觉很慢。其实．上网慢的主要原因是IPv6造成的。经过本人测试．从IPv6入手．的确可以提高上网速度。经过测试．笔者介绍两种的有效方法。

简介：上期我们报导过“技嘉公司采用i915P芯片组的GA-81915P-SLI主板也能实现SLO暨双显卡协同工作”的新闻，现在技嘉正式公布了让Intel915P实现多重GPU协同工作的技术名称为81915PDualGraphicsCore，支持NVIDIAGeForce6600GT与6800GT显卡，采用该技术的主板配备两组PCI-Ex16插槽，实际工作模式为一组x16加一组x4。目前尚不清楚是否有别家主板厂商也会在i915P芯片组产品上加入该技术或类似功能。
