Both are positive& keep that in mind because this is y and this is the increasing value of x.

都是正值，记住了，因为这是我定的，轴的增长方向，what，I，call，the，increasing，value，for，y，这是x轴的增长方向。

Positive rate of sialyl Lewis X expression was 96.1% in metastatic lymphatic nodes.

Carrot callus was transformed using the polyphyletic vectors by bombardment The transformed callus was detected to be blue by X-Gluc tinction, and to be positive by Southern blotting. The results indicated that the polyphyletic expressing vector was transferred into genome of carrot callous.

用基因枪转化法对胡萝卜愈伤组织进行了遗传转化，转化的胡萝卜愈伤组织经Southern杂交检测和X-Gluc染色，结果表明，多元表达载体成功地被导入胡萝卜愈伤组织。

F ( x) is the defined function. C is a constant and e is any positive number.

〕，其中F（x）就是本文中所定义的一个函数，C为常数，ε为任意正数，从而得到了一类推广的凸函数。
