If fluxed parts are allowed to stand , the water in the flux will evaporate , and dried flux is liable to flake off , exposing metal surfaces to oxidation 如果允许涂上焊剂的部件处于直立状态，那么焊剂中的水分会蒸发掉，而干燥的焊剂很容易脱落，致使暴露的金属表面容易被氧化。
The new element should be inserted smoothly through the hot furnace with sufficient speed to insure that the aluminum is not melted off the terminal end but not so fast as to cause thermal shock 新的硅碳棒应该轻轻的迅速放入熔炉，以确保铝不在终端被氧化，否则可能会导致温度急增。
Organic sulfides are to be oxidised to form polymers containing s - s bonds as charging , and polymers will be reduced to their low molecular monomer as discharging 这类物质在电池充电时,被氧化为含有s - s键的聚合物;在电池放电时, s - s键断裂,聚合物被还原为低分子量的有机硫化合物单体。
The new ones should be inserted smoothly through the hot furnace with sufficient speed to insure that the aluminum is not melted off the terminal end but not so fast as to cause thermal shock 新的管子迅速的放入管内的发热部以保证铝不会在终端被氧化，如果不那么快的话容易引起热震动。
The molecules of soft sections of sbs elastomers are not satuated and is easily to be oxidized . it is highly possible to create degradation by manufacturing in high temperature and high shearing rate Sbs软质段分子段有不饱和键，容易被氧化，高温或高剪切率加工产生材料降解degradation可能性高
The major target of photoinhibition is photosystem ii ( psii ) on which photoinhibition make photosynthetic efficiency decreased , electronic transportation blocked and reaction center protein dl photodamaged 已有研究表明ps是主要靶点，光抑制时表现为： ps光合效率下降、 ps电子传递链活性下降及核心蛋白被氧化而破坏。
For the special physical and chemical character of aluminum , a nickel layer is deposited before electroplating . it can avoid the active surface of aluminum oxidized again or substitution reaction in the bath 由于铝特殊的物化性质，电镀镍铬合金前采用预镀镍的工艺，避免活化后的铝基体表面再次被氧化或在镀液中发生置换反应。
The calculated activation energy was 136 . 45 kj / mol . it had been demonstrated that ti3alc2 had excellent oxidation resistance due to the dense continuous oxide scale consisted of mass a - al203 and little tio2 and / or al2tio5 C将在基体和氧化层界面处被氧化为co ，并最终在氧化层和空气界面被氧化成coz ，这种氧化行为使试样表面可形成连续的a一a12o3o
The defining feature is the gley horizon below the humus - blue - grey clay whowe color is due to ferrous iron compounds that have been reduced by microorganisms , flecked with localized areas of rust - colored oxidized ferric compounds 潜育土的一个重要特点是位于土壤腐殖质层之下，其土层呈灰蓝色是由于含有被微生物还原的亚铁离子，而且常有部分铁被氧化生成红棕色的锈斑。
Research points out that the three key factors , which determine the nox emissions , are maximum peak temperature , rich oxygen concentration and the duration in which combustion products stay at high temperature zone 船舶柴油机的氮氧化物主要是山于大气中的氮在柴油机燃烧过程中被氧化而成。研究表明高温、富氧以及燃烧产物在高温区的停留时间是决定氮氧化物排放量的三个决定因素。
