查询词典 existence conditions

The results under the oil lubricate friction conditions were similar with those under the dry friction conditions. The wear mechanism of 3Cr13 matrix alloy was micro-cutting and distorting wear. For the composites with a low fraction of TiC particle, distorting wear dominated and cutting was partly operating. For the composites with a high fraction of TiC particle, stress fatigue wear and wear of hard phase decohesion has occurred, but the main wear mechanism was still distorting wear. When the wear experiments were performed under the oil lubricate friction conditions, the main wear mechanism has became to abrasive wear and fatigue wear for the composites with the low TiC fraction, and fatigue wear would be to dominate for the composites with the high TiC fraction. There were similar wear mechanisms in H13 and 1Cr18Ni9 matrix composites.

在干摩擦条件下，3Cr13基体合金的磨损机理为显微切削和变形磨损；低体积分数的复合材料磨损机制以变形磨损为主，兼有少量的切削磨损机制；高体积分数的复合材料磨损机制以变形磨损为主，兼有应力疲劳磨损和脆性相剥落磨损；在油润滑摩擦条件下，3Cr13基体合金的磨损以磨粒磨损为主；低体积分数的复合材料磨损为磨粒磨损和疲劳磨损；高体积分数的复合材料磨损以疲劳磨损为主。H13、1Cr18Ni9基体及其复合材料的磨损机制类似于3Cr13基体及其相同体积分数的复合材料。

Firstly, according to electromagnetic field theory, the 2-dimensional (2-D) mathematical model of a three phase squirrel-cage Y802-2 induction motor is developed. Then general equations can be deduced from finite element discrete and functional analysis. The motor's 2D solving region of electromagnetic field is given based on the boundary conditions and assumption conditions of the squirrel-cage induction motor. Through finite element mothod and inner–outer convergence method, magnetic field distributions and magnetic forces of bars can be calculated in following rotor conditions: health rotor, one single broken bar, two adjacent broken bars, two broken bars with one good interval, two broken bars with two good interval and four adjacent broken bars.

Concretely, firstly with Timoshenko beams, the fundamental formulae of solutions of dynamical equations, boundary conditions and initial conditions have been transformed by Laplace transformation. Secondly, in the Laplace regions , we gain the analytical solutions of impact forces at the impact contact points, shear and maximum inverse stress of beams.

In iron-deficient cells, photosynthetic pigments content decreased, efficiency of photosynthesis was low, With the increase of the concentration of the iron-chelator 2, 2'-Dipyridyl in media, Fv/Fm decreased, indicating photoinhibition increased, the results were consistent with previous research; Heterocyst induction had one delayed time dependent on the status of iron-deficiency, More severe of the iron-deficiency condition, more late of the heterocyst induction, It is possible that certain iron-related genes may directly regulate heterocyst development; under different iron limitation conditions, Protein pattern were different, more serious of the iron-deficiency conditions, less bands of the protein pattern, We could not find the iron-deficiency induced protein; In general the toxic effects of ROS were potentiated by excess iron, But our results revealed that even under iron-deficiency conditions, Oxidative damage existed.

铁限制的细胞光合色素含量下降，光合作用能力下降，随着铁螯合剂2，2'-dipyridyl浓度的增加，叶绿素荧光F〓／F〓逐渐降低，显示光抑制变强。与前人的研究结果相似；依赖铁缺失状态，异形胞诱导有一段推迟的时间，铁缺失越严重，诱导越迟，推断某些铁相关的基因会直接调节异形胞发育；在不同铁营养条件下，蛋白质图谱的变化趋势很明显，缺铁越严重，则蛋白质谱带数愈少，但本文未能找到特异诱导蛋白；一般认为铁过量情况下ROS产生加强，本文结果显示即便在铁缺失条件下，也有氧化胁迫伤害，而且缺铁越严重，活性氧伤害越大。

Based on the research, founded on existing production conditions, production capability and technical natures of KISC, especially its own development requirements, linked with the development trend of the iron and steel industry, fully considering the continuity of equipment upgrade and technical optimization of KISC, guided under principles of validity and benefit, the writer analyses and argues that in current conditions. KISC shall not adopt the hot metal pretreatment of desiliconization, dephosphorization and desulphurization, but the end-point converter process to improve the dephosphorization effect. But according to the development plan of KISC, with its scale development, upgradeof equipment and technical conditions and implementation of a plan to use high-phosphorus ironstone, its more suitable to adopt the converter-shaped pretreatment of desiliconization, dephosphorization and desulphurization.
