exposed methods, e.g. vector::erase(). if it is an array and there is no
erase() method, most likely they won't simulate it.

能不是硬件问题，也许是软件问题？看看有没有知道。
这个固件用的是1999年SanDisk的API，Compact Flash。不知道当年有没有现在的wear
leveling，这个固件当年是否做这些还不清楚，还要看一下资料。
CF卡里面，一个page是512字节，可以写一次，随便读，继续写需要erase，一次erase
一个block既64个page。这是硬件层的。固件Api呢，是FAT16，每个文件必须占用64个
扇区为一个cluster，一个扇区512字节。这个层，我不清楚是否知道CF不能写一个扇区
多次，假设它不知道。软件层写文件的时候，每5秒更新一次，大约20个字节，这样，
假如api那里缓冲够了，就写入CF，而CF负责新找一个sector,把原来的标记为不可用，
这样可以延长寿命。每次写文件的时候，文件在目录表的记录也需要修改，文件长度和
时间要被改。
这个过程出现了问题。现在看到两个CF卡，其中某个目录里，文件的内容不仅出现在文

600多分都不满意，很多人报告的分数都是在700多，甚至750以上的。是不是在美国考

（2）官方介绍 GMAT考试各方面信息的一个小册子上说明很多私人物品，比如手表很外
套都不能带到考场里，请问考场里的温度大概是多少啊，如果比较冷的话，我可以穿个

（3）考试的时候工作人员会发给一个erasable noteboard booklet和一个marker。所

请原谅我问的问题比较简单，因为从来没有参加过GMAT考试。如果有人参加过，可不可

阿波罗11号使用的是专门生产的Lunar Camera，阿姆斯特朗走下登月舱等等珍贵的历史镜头都是首先由Lunar Camera拍摄，同时从月球将影音信号传回地球。一方面，NASA用遥感胶带存储，保留为原始影像记录；另一方面，信号传给电视台作为电视直播使用，当时直播的是CBS。由于当时Lunar Camera是特制，信号模式和电视信号模式不是完全兼容，转化起来不方便，所以当时电视直播转化出来的电视画面特别的模糊，实际上Lunar Camera的原始信号效果要好不少。
70、80年代，卫星技术大大普及，美国大量卫星上天，产生巨量数据，一时间NASA存储带短缺，无意中抓了存储阿波罗11号原始数据的带子来用，写进新的卫星数据，就erase了原始资料。这个失误确实很愚蠢，也很遗憾，但是发生在管理层越来越官僚的NASA内部，也不是那么意外。
