With the same final brightness about 84%ISO, O~*P pulp consumed less active chlorine and peroxide compared with the OP pulp; although O~*P pulp needed a higher beating energy,the tensile index,tear index and burst index of the pulp were better than those of OP pulp at the same ~oSR value.

当漂白浆的白度均为84%ISO左右时，与CK2 OP漂白浆相比，CK2 O~*P(O~*为表面活性剂S3强化的氧脱木素)漂白浆所消耗的漂白化学品的量更少，即氧脱木素段添加合适的表面活性剂能有效降低漂白化学品用量。

The results show that the perfect strength can be obtained under oxygen partial pressure about 20% O2, overhigh or low oxygen partial pressure is unfavorable for recrystallization of Fe2O3, which causes a decrease of pellet strength. The original hematite will be transformed into magnetite on reduction firstly when carbon-burdened hematite pellet is roasted in oxidizing atmosphere, and then the magnetite will be oxidized to secondary hematite, which is more active than original hematite, therefore, the induration strength of pellet is able to be enhanced.

研究结果表明：内配碳赤铁矿氧化球团在接近空气配比(氧含量约20%，体积分数)的氧化性气氛中焙烧强度最大，氧含量过高或过低都会影响Fe2O3的再结晶，使球团强度降低；在氧化性气氛中焙烧含碳赤铁矿球团时，原生赤铁矿先还原为磁铁矿，磁铁矿再氧化成活性较高的次生赤铁矿，提高了赤铁矿焙烧固结性能和球团强度。

That needs the trace elements enter the reaction of maintaining free radicals metabolism balance which can enhance the activity of anti-oxidate enzyme,the trace elements which can enforce the oxidate of the free radical needed to be reduced.This may decrease or increase the relevent trace elements.

这就需要血液中能增强抗氧化酶活性的微量元素参与到维持氧自由基代谢平衡的反应中，以及减少利用血液中能增强氧自由基毒性作用的微量元素，这就使得血液中相应的微量元素含量减少或升高。

It is a strong oxidizer that combines readily with many elements to form an oxide and is necessary to support combustion.

氧是一种强氧化剂，很容易同许多元素反应，生成氧化物。氧还是维持燃烧的必需品。

The experimental process on synthesis of roxithromycin was studied by using erythromycin oxime and MEMC as raw material under the catalytic action of anhydrous sodium carbonate.

研究了以无水碳酸钠为催化剂，红霉素肟与甲氧基乙氧基氯甲醚为原料，一步合成罗红霉素的实验过程。

An oxyacetylene torch; oxyacetelyne welding.

氧乙炔火炬；氧乙炔焊接。

Although the total calorific value of oxypropane flame is higher than that of oxyacetylene flame, its first calorific value is lower,so its burning temperature is lower and its heating time is longer.

氧丙烷焰比氧乙炔焰的总热值高，但一次热值低，因此燃烧温度低，预热时间较长。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
