positive ray

Elder-ray gives shorting signals in down trends when Bull Power turns positive and then ticks down.

在下跌趋势中,当多头力量变成正数,然后下跌时,艾尔德射线给出做空信号.

Meanwhile, the radial width of cambial fusiform cell had negative correlations with fiber length, ratio of fiber length to width and ratio of ray tissue, and a positive correlation existed between tangential width of cambial fusiform cell and fiber width.

形成层纺锤形细胞的径向宽度与纤维长度、纤维长宽比和射线比量呈显著负相关；形成层纺锤形细胞的弦向宽度与纤维宽度呈显著正相关。

Recall that the angles are positive if the ray has a positive slope.

记住,若光线之斜率为正则角度为正.

Conclusion The methods for determination of anteverted and abducted angle of acetabula in the positive X-ray films of hip joints are accurate and objective, simple. This method is easy to be carried out for much more accurate replacement for the acetabular prosthesis in THR operation.

结论在髋关节正位X线片上测算髋臼前倾角、外展角的方法是准确客观的，该方法简单易行，从而使THR术中髋臼假体的安置更加精确。

Results Among 103 gelatinase-producing strains, 77 strains were positive with nutrition gelatin method, 60 strains were positive with x-ray film method, 91 strains were both positive with the routine charcoal powder gelatin method and charcoal powder gelatin microtube method respectively.
