Based on data from a field survey in 2001 along the Northeast China transect (NECT), a precipitation gradient,and a short-term simulation experiment under ambient CO2 of 350 μmol mol-1 and doubled CO2 of 700 μmol mol-1with different soil moisture conte

我知道PSP除了游戏之外,还有能看电影的功能,那我可不可以把我自己喜欢的DVD大片装到PSP中来欣赏呢? A当初MP3刚起步的时候,曾经以推出“Walkman”随身听而一度风靡全球的的SONY娱乐部门就评估是否要进入MP3市场。但是由于SONY最后策略上决定不支持MP3,于是所有SONY的产品都不支持MP3这种红透半边天的音乐格式。

我的手机是带拍照功能的照相手机,可是平时用手机拍的照片只能存在手机看或是顶多当成手机的待机桌面来使用,请问怎样可以将手机中拍下来的照片打印出来呢? A在目前看来,将手机中的照片打印出来的方式有两种一种就是直接通过手机连接打印机打印,还有一种方法是通过手机内置的无线传输功能传送到电脑中再打印输出。由于第一种方式需要手机和打印机都支持PictBridge直连打印的技术,所以还不是那么普遍。
