Its main features are: algae body as a single cell or even into a variety of groups; cell walls composed of silica and pectin, but also by the structure of the shell and the shell under the combined set of the Cheng, vertical section view was "soap-box"-shaped; in the upper and lower shell surface of the shell are patterns arranged in patterns on both sides of the main mode of symmetry and radial symmetry is divided into two categories, for the classification of the most important basis; be able to campaign Type in the shell has a shell side seam, can not be changed no shell seam types; pigment body sheet or ribbon, 1 or 2, or for multiple small discoid, yellow green or brown, containing chlorophyll a, c, also contains fucoxanthin and silicon A flavin and other photosynthetic pigments; storage material mainly for oil droplets; reproduction mainly for cell division and cell division in diatoms obvious features are: each cell division, resulting from two sub-cells,, only one and the mother cell and so big, the other one is smaller.

其主要特征是：藻体为单细胞或连成各式群体；细胞壁由硅质和果胶质组成，而且在结构上都是由上壳和下壳套合而成，纵断面观呈"肥皂盒"形；在上下壳的壳面上有花纹，花纹排列的方式主要分为两侧对称和辐射对称两大类，为分类上的最重要依据；能运动的种类在壳面都有壳缝，不能动的种类均无壳缝；色素体片状或带状，1个或2个，或为多个小盘状，黄绿色或黄褐色，含叶绿素a、c，还含有墨角藻黄素和硅甲黄素等光合色素；贮藏物质主要为油滴；繁殖方式主要为细胞分裂，硅藻的细胞分裂的明显特点是：每次细胞分裂所产生的2个子细胞中，仅有1个和母细胞等大，另1个则稍小。

Axial distribution of activity ratio A ( 134 Cs)/ A ( 137 Cs) along the fuel rod with different burnup level,irradiation history and cooling time is measured by the γ scanning device. As a comparison, this distribution is calculated by the FCAC code used for the fuel rod failure analysis.

在热室中，用γ扫描装置对秦山核电厂 3× 3 -2考验组件中辐照历史、燃耗及冷却时间不同的两根燃料棒中的铯活度比A(13 4 Cs)/A(13 7Cs)的轴向分布进行了测量，并利用自行开发的压水堆燃料棒破损特性分析程序FCAC进行了理论计算。

P table plus full exterior defect sector after more than g, it can not g to p a, g table full of new and emerging sectors of the defects have no place to go on, but also a phenomenon in my "smart is a double-edged sword,"Lane said, after the destruction of six keywords section, and even write a bad firmware.

p表加满了，以后g表里缺陷扇区多了，就不能g转p了，g表满了新出现的缺陷扇区就没有地方去了，还会出现象我在《s.m.a.r.t。真是一把双刃剑》里所说的，毁坏表后的6个关键字节，甚至写坏固件。

Each letter is used exactly once.1{"ABC","FED","GAI"}"ABCDEA"Returns: 2Once we get to the ''E'', we can choose one of two directions for the final ''A''.2{"ABC","DEF","GHI"}"ABCD"Returns: 0We can trace a path for "ABC", but there''s no way to complete a path to the letter ''D''.3{"AA","AA"}"AAAA"Returns: 108We can start from any of the four locations.

在例1的find字符串的第一个字符是''A''，我们可以看到在相应的grid中，''A''在两个位置上出现，由于起点不限，所以我们搜索到的起点有2个；find的第2个字符是B，我们可以看到grid中只出现了1个B，而按照题目要求移动的话，显然只有左上角的那个A可以移动到这个B的位置。
