数一数

Choose any two digit number,add together both digits and then substract the total from your original number.

任意选择一个两位数（或者说，从10~99之间任意选择一个数），把这个数的十位与个位相加，再把任意选择的数减去这个和。例如：你选的数是23，然后2+3=5，然后23-5=18

Thetic devices that look so real, most people don't notice they're there.2 A painter by training, Barron designs pores, veins a=(100+2)×43 atients. The finding means that Alzheimer's, which affects 4 million Americans and millions more around the world, may be diagn

在此基础上引导学生观察这类题目的特点，以及怎样应用乘法分配律，从而使学生明确：两个数相乘，把其中一个比较接近整十、整百、整千的数改写成一个整十、整百、整千的数与一个数的和，再应用乘法分配律可以使计算简便。

An efficient Sphere Decoding algorithm is proposed for uncoded Multi-Input Multi-Output systems with a large number of antennas and higher modulation constellations. This method utilizes a channel-based group detection strategy.

摘要该文针对无编码的多输入多输出无线通信系统中的最大似然检测接收机在发端天线数较多、调制阶数较高时计算复杂度过高的问题，提出了一种低复杂度的球形译码算法。

Among different organ explants from ginger lily, only sheaths and leaves cultured in VW medium containing 5mg/l 2, 4-D、0.5mg/l BA、3% sucrose and 200ml/l coconut water for 3 months could be induced to form embryogenic callus. It could produce lots of germinated or ungerminated somatic embryos per culture directly from the surface of calli after culture in MS medium containing 4mg/l BA and 0.05mg/l NAA. The shoots could develop into intact plants with vigorous appearance after 2 months in culture.

叶鞘及叶培植体在含5 mg/l 2，4-D，0.5 mg/1 BA、3%蔗糖及200 ml/1椰子水的VW固体培养基中，经3个月，可诱导产生具体胚分化能力之愈合组织；并於含4 ms/l BA及0.05 ms/l NAA之MS培养基中，直接由此愈合组织的表面产生数个至数十个数目不等之体胚，2个月后可形成一完整植株。

Considering the final score, it's hard to imagine the game was tied when Gerald Laird (3-for-5) tripled to rightfield to lead off the fifth, a drive Bobby Abreu didn't play well near the wall.

T 这个最后的比数，让人很难相信当Gerald Laird〔五支三〕在五局率先上场打出三垒安打时，比赛还是以1比1平手，当时Abreu没有处理好这个打到墙边的飞球，在一出局之后，Gerald Laird还是留在三垒，而当Brad Wilkerson 打出三垒滚地球被A-ROD接到传给Posada时，这应该是个必死的出局数。
