In the framework of Filippov solutions and on the basis of Lipschitz continuous and regular scalar Lyapunov functions, this dissertation discusses the stability problems of nonlinear systems with discontinuous right-hand sides with respect to a given point or a closed invariant set, and have some related results.

本论文在Filippov解的意义下，基于Lipschitz连续且正则的标量Lyapunov函数，讨论了右端不连续的非线性系统相对一个给定的点或相对于闭不变集的稳定性问题。

Main contents and conclusions are: 1 The ionization current was measured continuously by a charge-integration method with a computer after the introduction of radon into the chamber.

主要内容及结论：1充氡后利用计算机连续进行电离电流累积测量，得到了精细的电流随时间的变化曲线，可清楚看出氡及其子体的生成衰变造成的电离电流的生长—稳定—衰减过程，与理论计算值进行了比较，由电离电流衰减速度的变化得出氡吸附作用的影响，并测量到电离室冲洗后氡的反扩散现象；2由已知活度的标准源定出相对测量的刻度系数K值，K=24.62 Bq／pA，对同一个监测源以半年为周期进行多次测量后得出稳定性符合要求；3通过测量电离电流和气压的关系曲线以及不同气压下的饱和曲线，确定了常规的工作条件；4测量了盐酸清洗电离室内表面降低本底的效果；5不确定度分析表明相对测氡的扩展不确定度(k=2)小于5％，由本底涨落得出探测下限为0.5 Bq；6理论上对壁损失修正进行了计算，实验上保持电离室工作在饱和区的情况下，测量了不同气压下电离电流的变化，从中得出了壁损失随气压变化的规律，可以看出，电离电流的实测值和计算值随气压变化规律基本一致；当气压大于125 kPa时，端效应等其它因素造成的影响不大于2％，因而在此工作条件下，测量电离电流后通过计算修正壁损失可以实现近似的绝对测氡，提出了进一步提高绝对测量准确度的方法。

分析结果同时证明，如果在川西深层采用定向井钻井，其井壁稳定性将不会因为井斜角、相对方位角的变化而变差，且地层破裂压力会随井斜角和相对方位角的增加而大幅提高。

Edit in what defend Jian measure respect, the main opinion that gathers before this includes: It is to suggest not to lengthen the orgnaization that protect Jian to doing poineering work board the superintend and director of the company guides period, card inspect can think through research, because do poineering work board company dimensions is relatively lesser, management stability is relatively inferior, lengthen superintend and director to guide appropriately period be helpful for active and reliable roll out do poineering work board, reason did not grant to adopt; 2 it is to suggest exempt does poineering work board company IPO in those days namely the responsibility of the person that protect Jian of deficit, card inspect can think via research, although do poineering work board the company is managed not stable, but if the company appears on the market in those days with respect to deficit, can produce baddish effect to the market, because this cannot loosen the responsibility of pair of people that protect Jian to find out; 3 it is to suggest to unlock person of the delegate that protect Jian to sign odd number to measure limitation, meeting general is keeping next card watch in be being arranged related Jian system, give further research, hear opinion of orgnaization of Jian of be bailed out, make arrangement jointly.

在保荐办法的修订方面，此前收集到的主要意见包括：一是建议不要延长保荐机构对创业板公司的督导期，证监会经过研究认为，由于创业板公司规模相对较小，经营稳定性相对较低，适当延长督导期有利于积极稳妥推出创业板，故未予采纳；二是建议豁免创业板公司IPO当年即亏损的保荐人责任，证监会经研究认为，尽管创业板公司经营不稳定，但如果公司上市当年就亏损，对市场会产生较坏的影响，因此不能放松对保荐人的责任追究；三是建议放开保荐代表人签单数量限制，下一步证监会将在保荐制度相关安排中予以进一步研究，听取保荐机构意见，共同做出安排。

The relationship between the tracking error and those auxiliary errors is clearly established when plant relative degree is greater than one and therefore, it can be proved that the influence of averaging filters on a VS-MRAC system can be considered as, in a sense, an unmodelled dynamics. As a result of this, it is shown that the stability analysis of a signal synthesis based VS-MRAC system must be modified to include the 'unmodelled dynamics'.

当对象建模部分相对阶大于1时，得到了系统跟踪误差和辅助误差间明确的关系表达式，进而证明平均值滤波器对系统的影响相当于未建模动态对系统的影响，这表明以往相关文献关于系统稳定性的分析是有缺陷的，没有将平均值滤波器对系统稳定性的影响完全考虑在内； 3。

Compared to the silk, moisture regains, level dyeing and thermal behavior of raw silk grafted by MA was better. The K/S value increased a little, the fastnesses decreased a little. But the level dyeing of raw silk grafted by EMA declined severely. Compared to the grafted degummed silk, the moisture regains and level dyeing improved a little.

MA生丝增重丝相对于熟丝吸湿性提高、酸性染料染色的K/S值略有上升、匀染性提高、各种染色牢度变化不明显、热稳定性有所提高；而EMA生丝增重丝吸湿性下降、酸性染料染色的K/S略有上升、匀染性变差、各种染色牢度略有下降、热稳定性有所提升。

Every community was stable relatively. Interspecific association was the loosest and stability was the highest in Q. wutaiensis community. But the insignificant positive association among species showed that Q. wutaiensis community has not reached the stable state, so we still should protect the local natural vegetation reasonably for a long time.

演替系列各群落都具有相对的稳定性，演替顶极辽东栎群落的种间联结性最弱，稳定性最高，但多物种间不显著的正相关说明该地区分布最广、面积最大的辽东栎群落可能尚未达到稳定状态，仍需要对该地区天然植被进行长期保护。

The high risk zone mainly contributes in the fore section of study area, which is 15% of the whole area. This zone is the key limit zone of human activity. The middling risk zone mainly concentrates on mid section, which is 25% of the total area. This zone will be exploited with relevant engineering and non-engineering steps to reduce hazard. The low risk zone contributes in the mid-back section, 60% of study area. It is the most-making zone.

高风险区主要集中在研究区前缘，约占总面积的15％，范围较稳定性差区有所扩大，是今后人类活动的重点限制区；中等风险区主要分布在中部的稳定性中等、人类社会经济活动相对集中区，约占总面积的25％，该区可通过采取相应的工程措施和非工程措施进行防灾减灾，加以开发利用；低风险区主要集中在中后部，约占总面积的60％，是可充分利用的地带。

This outlook needs to be seen within the historical context of eighteenth century Scotland, where the legacy of religious civil war, combined with the relatively recent memory of the 1715 and 1745 Jacobite risings, fostered in a historian such as Hume a distaste for enthusiasm and factionalism that appeared to threaten the fragile and nascent political and social stability of a country that was deeply politically and religiously divided.

这种看法需要放到18世纪英格兰的历史情境中来理解，在18世纪的英格兰，宗教内战的传统，再加上对相对较近的1715年和1745年的詹姆斯二世叛乱的记忆，促成了休谟这样的历史学家对威胁国家稳定性的狂热与党派之争的厌恶，在政治和宗教上苏格兰深受深度分裂之害，新生的政治与社会稳定性十分脆弱。
