计数

Battista and Clements(1996, 1998) indicate that students are difficult to perspect and imagine the hiding cubes, or coordinate orthogonal views of cubes correctly.

Battista与Clements(1996， 1998)指出学童在解决立方体计数的问题时，无法对隐藏的立方体进行透视与想像，或无法正确协调柱体直角的视点，即使到了国小高年级，仍有一定比例的学生计数错误。

By the combinatorial proof or combinatorial interpretation, the identity is equipped with certain count meaning. The most general way in the combinatorial proof is to count two sides of the identity by two different methods. Generaly, through building a bijection from one set to another one, the number of the two sets respectively represents the two sides of the identity.

恒等式的组合证明或组合解释赋予了恒等式一定的计数意义，组合证明最常用的方法是分别用两种不同的方法对恒等式的两端进行计数，一般通过构造两个集合之间的双射，这两个集合的个数分别表示恒等式的两端，从而根据双射的一一对应性证明恒等式。

Moreover, by the combinatorial proof or combinatorial interpretation, the identity is equipped with certain count meaning. The most general way in the combinatorial proofs is to count two sides of the identity by two different methods. Generaly, through building a bijection from one set to another one, the number of the two sets respectively represents the two sides of the identity. Because of the 1-1 property of bijection, the identity is proved.

Routine detecting techniquefor cell immunity such as white blood count and differential, lymphocyte blastogenesis test has beenused, and combine with flow cell technology to detect the level of cell immunization after advancedimmunization at several important aspect, and tracking experiments to observe changes in the numberof the WBC and lymphocytes, lymphocyte proliferation, the dynamic changes of CD4~+ and CD8~+lymphocyte subsets andγ-IFN; and detected dynamic changes rules of IgG, IgM in humor andmucosa with indirect ELISA, then compare with ordinary immunization methods.

主要采用白细胞计数和分类计数、淋巴细胞转化试验等常规细胞免疫检测技术结合先进的流式细胞技术从细胞免疫的几个重要方面入手检测猪瘟超前免疫后细胞免疫的水平，并进行跟踪试验，观察其白细胞、淋巴细胞数目变化情况，淋巴细胞增殖情况，CD~(4+)和CD~(8+)淋巴细胞亚群及γ-IFN的动态变化规律；同时通过间接ELISA方法检测体液和黏膜中各IgG、IgM的动态变化规律，同时与普通免疫方法进行比较。

Omputation of Car group PMN is remarkable when R2 and R6 under;PMN of I/R group bandicoot breath erupts the metabolic rule of intensity and PMN computation are consistent.

ar组PMN计数在R2和R6时显著低于I/R组大鼠；PMN呼吸爆发强度的变化规律和PMN计数一致。

The number of EOS in peripheral blood were counted by counting plate and the morphological changes in bronchia and EOS infiltration in lung tissue were observed. The content of NO and ET-1 in blood serum and BALF were measured by biochemistry and radioimmunity methods.

用计数板计数外周血嗜酸性细胞数量，观察小支气管形态学改变和肺组织中EOS浸润情况；生化法和放免法测定血清和肺泡灌洗液中一氧化氮和内皮素－1(ET-1)的含量。

Combined Sensory inspection, Colony counting and E. coli counting, we found that: mixed-Potassium cinnamate had clear preservation results in pickles, when the content was 0.2% under sterilization, only slightly dark color of the phenomenon after saving 84d, and texture, taste and smell of pickles were not significantly changed.

结合感官检查、菌落计数和大肠杆菌计数发现：肉桂酸钾对酱腌菜有明显的防腐保鲜效果，且在灭菌条件下添加量为0.2%时，保存84天仅有轻微颜色发暗的现象，酱腌菜的质地、口感和气味均无明显的变化。

And the ratio of the number of clock pulse in delay time and the number in signal period is the ratio of delay time and the signal period. It can get the phase difference from the ratio.

鉴相脉宽内的计数结果与原始信号周期内的计数结果的比值，即是鉴相脉宽与被测信号周期脉宽的比值，从而计算出相位差的测量方法。
