In order to find a stable approximate solution of linear compact operator equation, the article introduces general theories about ill-posed problems, it bases on spectral theory of self-adjiont compact operators and the singular value decomposition for compact operators, avails singular system to give expression of the solution, and explains ill-posedness of compact operator equation roots in the property that the singular values trends to zero. Thereout, it is provided with theoretic support of building up regularization method by inducting regularization filter to weaken or filtrate the influence that the nature of the singular value being very close to zero has on the solutions stability.

为了得到线性紧算子方程稳定的近似解，介绍了不适定问题正则化的一般理论，以自伴紧算子的谱分析与紧算子奇异值分解为理论基础，利用奇异系给出了解的表达式，说明了紧算子方程不适定性的根源在于紧算子的奇异值趋于零的性质，由此通过引入正则化滤子函数来减弱或滤掉奇异值趋于零的性质对解的稳定性的影响，构造正则算子，从而提供了建立正则化方法的理论依据。

The paper fristly compared the fertile soil with the incinerated sterile soil on the number of micro-algae , soil pH value , soil organic matter soil available phosphorus and soil nitrogen.And then, the author put fertile soil, which included micro-algae, proportionally into sterile samples and cultivated them respectively under illumination condition (micro-algae can live and reproduce)and dark condition(micro-algae will die in some time).The above indices were measured in 0, 30, 60 and 90days respectively, The analyse of the interrelation between the change of micro-algae"s number and the changes of soil pH value, soil organic matter, soil available phosphorus and soil nitrogen indicated:Soil micro-algae which were native to fertile soil conld adapt to the changed circumstance and light acted as a decisive role to the distribution of soil micro-algae.Under dark condition,the micro-algae"s number declined gradually and went to zero in the end,while under illumination condition ,on the 90th day, the micro-algaes number of per gramme was 6-7 times more than that of the beginning.

本文首先对肥沃土壤与经高温焚烧后的贫瘠土壤中的微藻数量、土壤pH值、有机质含量、有效磷含量和全氮量进行比较研究，然后将包含微藻的绿化苗圃地肥土按不同比例接种进入贫瘠土样中，分别在光照条件和黑暗条件下进行培养，在0天、30天、60天和90天分别检测以上指标，比较有光条件和无光条件下，即有藻条件和无藻条件下贫瘠土样所发生的变化，并分别对微藻数量的变化与土壤pH值、有机质含量、有效磷含量和全氮量的变化之间做相关性分析，以评估肥沃土壤中的微藻接种进入贫瘠土壤后的生长情况以及对贫瘠土壤的改良作用。

In classical music I always admired Mussorgsky's unorthodoxy, unpredictability and disrespect of rules, and a few other Russian composers such as Shostakovich (the second tempo of his 8th String Quartet and Chamber Symphony op.110/110a electrocuted my imagination at least as much as the beginning of his 5th Symphony must have remained stuck in Morrissey's mind, when he sampled it for 11 minutes on the opening song of his "Southpaw Grammar" album), Prokofiev (whose exceptional melodic ingeniousness influenced me, but must have pleased Sting too, as he borrowed the theme of Prokofiev's "Lieutenant Kijé" for his hit "Russians") and Mosolov (whose mid-1920s piece "Iron Foundry" is pure Prog-Rock à la Magma, Art Zoyd, Univers Zero).

古典音乐家里面我一直十分欣赏Mussorgsky的叛逆、不可预测以及他对常规的无视，还有少数俄罗斯作曲家，比如Shostakovich，（他的C小调第八弦乐四重奏作品第110号/110a的第二部分 [1]强烈激发了我的想象力，这种激发不亚于他的第五交响曲[2]的开始部分对于Morrissey[3]的影响，那段旋律令他印象如此深刻以至于他将11分钟的采样放在了他的专辑《Southpaw Grammar》中。）Prokofiev（他格外出色天才一般的旋律影响了我，但是Sting肯定也获益匪浅，因为他也在自己的热门单曲"Russians"俄罗斯人中借用了Prokofiev 的"Lieutenant Kijé"三驾马车[4]），和Mosolov[5]（他创作于1920年中期的作品"Iron Foundry"是纯粹的前卫摇滚à la Magma，Art Zoyd，Univers Zero）。

In order to make clear the phenomenon of current zero in the arc-quenching chamber of deion plates, the process of dielectric recovery and reignition of short arc between iron plates is investigated, and then the dielectric recovery strengths of various chambers are measured and compared. The different characteristics near current zero in the deion plate chambers are also analyzed based on experiments in the paper.

为弄清栅片灭弧室内电弧电流的过零过程，专门研究了不同条件下栅片间低压短弧的介质强度恢复过程和电弧重燃过程，然后测量了多纵缝和栅片灭弧室的介质恢复强度，对比了它们的熄弧性能，在试验的基础上，分析了栅片灭弧室中电弧电流的过零特征。
