在激光陀螺自洽场方程组的基础上，运用LabWindows/CVI软件建立了灵活方便的激光陀螺仿真平台，并进行仿真试验，仿真试验结果与理论分析很好的相符合，且能够较好地说明陀螺试验现象，即在闭锁阈值附近，由于闭锁效应和模竞争相互影响，使得激光腔中两行波相互关联，光强差随时间呈周期性变化。

The preventive measures for the harmful defects of alkali metals are as follows: 1, reducing the alkali metals content in the raw materials; 2, increasing the MgO content of the sinter , decreasing the basicity of slag , decreasing the Si content of the pig iron, increasing relative slag volume; 3 , introducing prereduced ore pellets or partly reducted sinter; 4increasing the ability of coke resisting alkali metals; 5, using refractories that have the ability of resisting corrasion of alkali metals; 6 , cleaning the blast furnace periodically. The above recommendations are necessary for decreasing the circulation and accumulation of alkali metals effectively in blast furnace, reducing the harmful influence of alkali metals on blast furnace, increasing the smelting intensity, decreasing the coke rate, improving the gas permeability.

基于碱金属对高炉冶炼的上述危害，本文结合湘钢高炉的实际生产情况，通过理论分析、计算以及其他钢厂防治碱害的经验，提出防治高炉碱害的措施：1、减少入炉原、燃料的碱金属含量；2、提高烧结矿中的MgO含量、降低炉渣碱度、降低生铁含硅量、适当增加渣量；3、采用预还原的金属化球团或部分还原的烧结矿；4、提高焦炭的抗碱能力；5采用抗碱侵蚀的耐火材料；6、周期性性洗炉，以有效地减少碱金属在高炉内的循环富集，降低碱金属对高炉的危害，提高高炉的冶炼强度，降低焦比，改善高炉透气性。

Equation with double cosine function can improve the accuracy of prediction when facing two peak time series data .

Critical damping is defined as the least amount of viscous damping that causes a single degree-of-freedom system to return to its original position without oscillation after initial disturbance.

在第一次受力后，来自阻尼器的阻力使振动物流刚能不作周期性振动便能最快地回到平衡职位的情况，称为临界阻尼。

In this paper, it is pointed out that the accuracy of measurement must be considered for the discussion about the restitution time of damped vibration, and it is in the "critical state of weakly damped vibration" defined by this paper, not the critical damping state, that the restitution time is the shortest.

1 问题的提出和回复时间的定义众所周知，阻尼振动按阻尼的大小可分为弱阻尼、临界阻尼和过阻尼三种情形。几乎所有的教材均指出，临界阻尼运动是物体刚能不做周期性运动而又最快地回到平衡位置的运动，也即其回复时间最短。

As far as free proline content was concerned, that of EI plants was less than EF plants due to higher water-holding ability of EI plants (such as in field plot and field pot sustained drought stress), or due to less damage of membrane of EI plants (such as field pot cyclic drought stress and greenhouse osmotic stress).

至于脯氨酸含量的变化，或是由于感染植株保持体内水分的能力更强（固定样地和田间盆栽持续性干旱胁迫下），或是由于感染植株叶细胞膜结构受到的伤害程度更小（田间盆栽周期性干旱胁迫和温室渗透胁迫下），感染植株的游离脯氨酸含量均低于非感染植株。
