原来一直mathematica启动时会出现和中文字体(应该是)有关的一个错误(类似无法找到一类的错误,具体忘了),只能将系统调成英文才能启动,但是这样无法输入中文;
1月6日升级的libsoprano4(应该是,版本1.99~rc2-1ubuntu1~gutsy1~ppa1)使得mathematica在启动时会出错出现类似mathematica字体没有正确安装的错误提示并无法启动;
1月8日libsoprano4升级成1.99~rc2-1ubuntu1~gutsy1,虽说升级说明里面说源代码并没有改变,但升级后mathematica可以直接正常的启动了,并且可以直接输入中文。(以上为比较准确的猜测)
** 如果您也在使用mathematica 6,请注意一下最近的更新 **
效果见图:

libsoprano4:
librdf0:Qt4 interface to RDF storage
Soprano (formally known as QRDF) is a library which provides a nice Qt4
interface to RDF storage solutions. It has a modular structure which
allows to replace the actual RDF storage implementation used.
Currently Soprano implements one fully functional backend which is based
on librdf, the Redland RDF Application Framework.
This package contains the runtime library files needed to run software
using libsoprano.
关于rdf:Redland Resource Description Framework (RDF) library
Redland is a library that provides a high-level interface for RDF
(Resource Description Framework) implemented in an object-based API.
It is modular and supports different RDF/XML parsers, storage
mechanisms and other elements. Redland is designed for applications
developers to provide RDF support in their applications as well as
for RDF developers to experiment with the technology.
