The leavels of myeloperoxidase, ratio of DNA chain, total nitric oxide synthase, inducible nitric oxide synthase and constitutive nitric oxide synthase in the gut were determined.

Use megohmmeter of 2500V for measurement,the megohmmeter must be checked and was ok , supply power to phase need testing and measure 12 insulation,write down the measurement values in 15"and 60",the ratio of R60 and R15 is namely the absorption ratio;stop measuring after 1 minute,make discharging for phase tested,measure insulation resistance for the other two phases.

3.6.2 测量绝缘电阻与吸收比： measure insulation resistance and absorption ratio 采用 2500V 兆欧表进行测量，兆欧表校正无误后，接通被试相进行绝缘测定，并分别记录 15"和 60"时的兆欧表示值，R60 和 R15 之比值即为吸收比， 1min 后停止测量，并对被试相放电后，改接线测量另两相的绝缘电阻。

The Best's data reflect the experience of practically the entire industry, including stock, mutual and reciprocal companies. The combined ratio represents total operating and loss costs as compared to revenue from premiums; a ratio below 100 indicates an underwriting profit, and one above 100 indicates a loss.

调查机构Best的数据正说明了目前整个产业，包含股市、共同基金以及相关公司，所面临到的状况，Combined Ratio系表示经营成本加上理赔损失除以保费收入的比率，若比率小于100 %则表示有核保利益，反之则有核保损失。

Unbraced Length Ratio means if the distance between lateral bracing. If the ratio is small, the capacity of the beam might reach 0.66Fy. If the ratio is small enough, it will reach 0.66Fy. On the other hand, if the ratio is high, then then capacity is low.

答：应该是平面外支撑的问题吧， Unbraced Length Ratio中的数值并不改变程序计算出来的结构的内力，但是却能改变杆件的承受力和变形的能力，数值越少，就是说不支撑的距离越短，承载能力也越强，那么 ratio 肯定就越小，结构会越稳定。

Seen days after an ACS eent, neopterin leels 12.11 nmol/L (upper quartile, deried from a post hoc analysis) were associated with an increased risk of death and an increased risk of death or acute coronary eents after adjustment for age, gender, history of diabetes mellitus, history of hypertension, history of smoking, type of ACS presentation, use of percutaneous coronary interention for the index eent, statin regimen, low-density lipoprotein cholesterol, and high-sensitiity C-reactie protein (hazard ratio, 1.86 [95% CI, 1.24 to 2.77], P=0.003; and hazard ratio, 1.33 [95% CI, 1.09 to 1.63] P=0.006, respectiely).
