  cut off value
The normal cut off value for this assay was set at 45 AU (mean +2 SD).
      
In this study compared to American and European studies a much higher cut off value of serum ferritin had most diagnostic power for detecting iron deficiency.
      
Of these, six had a blood IRT level above the cut off value (99th percentile) and a negative sweat test in the first trimester of life.

  division value
It is shown how to eliminate these spurious noise lines by using digital ΔΣ modulators to control the frequency division value.
      
In addition, the counter frequency division value setting and pull-in mode setting are saved.
      
That is to say, the counter frequency division value is set after waiting for up to one cycle of the previous comparison cycle.
      
Therefore, the frequency division value should be set in sync with the counter output so as to avoid the preset timing.
      
The phase detectors can operate at a maximum speed of 25 MHz, permitting better phase noise due to the lower division value.

本文利用松辽盆地南部地区扶余油层中有代表性的287个水样,采用判别分析,对数据进行处理,绘出了该区八元判别函数式及 R 等值线图。分析了苯和有机酸各50个水样,确定了含油层水与非含油层水的分界值。利用综合判别值(R)及有机组分含量,可预测有利的含油、气地区。

Based on the diagram of I-values(initial ~(87)Sr/~(86)Sr ratios)for granite genetic classification (based on Wu Liren, 1985, slightly modified), three linear equations nepresenting AB,CD EF lines in Fig. 1 and have been presented in this paper.

本文根据吴利仁的锶同位素初始比值(Ⅰ值)演化图解,计算出划分花岗岩成因类型分界线的三条直线方程:(1)幔源型与幔壳混源型分界线方程;(2)混源型与壳源型分界线方程;(3)壳源型中,下地壳与上地壳分界线方程。只要知道一个花岗岩体的形成年龄和Ⅰ值,就可以根据三个方程的分界值准确地判定其成因类型。这种利用Ⅰ值线方程定量地划分花岗岩成因类型的方法,符合Ⅰ值随时间推移而增长的规律,比目前采用的固定值法更加合理。此外,根据(1)、(2)二个方程,应用杠杆原理,还可大致估计幔、壳源岩的百分比。

The author proposes a new glacious rock classification and naming scheme on the basis of researches on the Sinian system in Southern and northern Anhui province in the, 1960s and 1980s with reference to various schemes suggested by geologists at home and abroad.

本文所提冰成岩,系指与冰川活动有成因联系的岩类总称,它包括冰川直接堆积而成的冰碛岩以及与冰川有关的沉积岩类(陆松年等,1985),作者据近年科研、教学实践,参考国内外学者不同方案,综合研究后提出新的冰成岩分类三角图解,其特点是采纳了现代冰川学中某些新概念,如“极限粒级”、“特征峰”等,作以端元粒径的最佳分界值,从而使结构分类兼具成因意义,据此将冰成岩分为五大类十五种,并对命名原则及细节作了探讨。
