First is the Chinese esthetic idea, the Chinese drawing is fastidious "is mad the rhyme vividly""gufa with the pen", the line not only has the modeling the function, moreover also has the function which flirts to express one"s ideas, compares western the line, in the Chinese drawing line subjective initiative stronger, the load bearing content is richer; Second was describes the object differently to decide line utilization rich; Third, China always is fastidious "the calligraphy and painting homology, therefore calligraphy line consciousness melted into the drawing in the very great degree.

首先是中国审美观念，中国绘画讲究&气韵生动&&骨法用笔&，线条不仅有造型的功能，而且还有传情达意的功能，相比较西方的线条，中国绘画中的线条主观能动性更强，所承载的内容更丰富；第二就是表现对象的丰富性决定了线条形式的多样化；第三、中国历来讲究&书画同源&，所以书法的线条意识在很大程度上融入到了绘画当中。

In the frame of constructing hydrodynamical model, some basic assumptions and equations were described in detail. Besides, there are three distinguish improvements above the former work: a new formula of chromosphere radiative loss was deduced out, which can roughly reproduce the results calculated by detailed non-LTE theory; a new physical process, i.e.

在构造耀斑动力学模型理论框架中，我们详细交待了基本假设和基本方程组，以及方程中各项的选取情况；针对现有耀斑动力学模型色球研究的不足，文中导得了新的色球辐射损失经验公式，它基本能够再生现有详细非局部热动平衡计算结果，较以前的处理方法有很大程度上的改善；引入了以前在耀斑环研究中从未被考虑过的日冕软x辐射加热色球的能量过程，推得了日冕软x辐射色球沉积的自恰公式。

The results show that the construction of the railway has an obvious effect on the warm steppe,but the characteristics of community,such as the coverage,ecological dominance and species richness of communities have been improved after its natural restoration,and some species,such as Elymus nutans,Aconitum gymnandrum and Thermopsis lanceolata,play an important role in the restoration communities.An assistant measure taken by human beings will benefit to the restoration.There is no any evidence of exotic invading plants in the restoration of the warm steppe in the study area.

结果显示，青藏铁路修筑过程对铁路两侧一定区域的温性草原有较大影响，但随着受影响区域植被的自然恢复，群落盖度、生态优势度和物种多样性等反应群落特征的指标都有一定程度的改善，一些在原生植被中很少出现或伴生种在恢复后的群落中有可能成为群落的优势种或建群种，如露蕊乌头和鹅绒委陵菜等；人为辅助措施将有利于受损植被的恢复；修筑铁路过程中受到影响的温性草原其恢复过程中尚未出现外来入侵植物。

Its ideal is that modulation mode can be adaptively adjusted by estimating such wireless parameters as fading degree,channel traffic and etc. Channel capacity will achieve a maximum and system performance will be best anytime. By this way,although mobile wireless channel broadband is more and more congesting today,adaptive modulation can be provided preferable spectral efficiency and can be increased the information transmission rate.

它的主要思想是通过研究无线信道的衰落程度、信道流量等参数动态地改变调制方式，在任何时刻都使信道容量达到最大或者使系统性能达到最佳，从而使移动无线信道频带日益拥挤的今天能得到较高的频谱利用率，有效地提高信息传输速率、从而提高传输系统的带宽。

Latin America provides a contrast between Argentina, which since the debt crisis of 2001-02 has enjoyed rapid growth based on a cheap currency and low interest rates, and Brazil, which has followed a much more orthodox monetary policy.

在拉丁美洲，阿根廷和巴西是很好的对比。阿根廷在2001年到2002年的债务危机后一直保持较低的汇率和利率，并在此基础上形成了经济的快速增长；而巴西则在很大程度上遵循传统的货币政策。

The influence of impulse voltage waveshape on particle-initiated breakdown voltage of a GIS system in SF6 and SF6/Air mixtures is reported. The results are compared with the characteristics of air gaps. For the SF6 gaps, breakdown voltage depends on wave-front duration but almost independs on wavetail duration. For the gaps in SF6/Air mixtures, the influence of impulse waveshape also depends on SF6 contents and electrical field non-uniformity

作者研究比较了正极性冲击电压波形对SF_6、空气、SF_6/空气的 GIS 电极装置由固定导电微粒引发的击穿电压的影响，结果表明：SF_6间隙的击穿电压受冲击电压波前时间长短的影响较大，而与波长的关系不大，当采用SF_6/空气混合气体时，则这种影响随SF_6含量增大而愈明显，并与电场不均匀程度有关。

Abstract］ objective to understand the medical institutions in the use of pressure steam sterilizer in the effect and the influencing factor,explore regulatory measures.methods with the spot investigation and scene examination,3mtmattest pressure steam sterilization and biological indicator train was used to monitor the effectiveness of disinfection.results in the monitoring of the 238 chinese medical institutions equipped with pressure steam sterilizer 337 units,the sterilization rate was 95.2%,medical institutions had different levels of disinfection and sterilization equipment,a large gap was between the level of management,equipment failure,non-standard operation,operator training without sterilization were the main reasons for failure.conclusion in medical establishment with the pressure steam sterilizer,antiseptic qualified rate is not too high,strengthening the pressure steam sterilizer purchase card management,standardizing the operation,stepping up supervision are the key to increase pressure steam sterilizer sterilization effect.

目的 了解医疗机构使用中压力蒸汽灭菌器使用效果及影响因素，探讨监管措施。方法采取现场调查及现场检测相结合的方法，采用3mtmattest压力蒸汽灭菌生物培养指示剂进行消毒效果监测。结果在监测的238家医疗机构中共有压力蒸汽灭菌器337台，灭菌合格率为95.2%，各级医疗机构对消毒灭菌设备的管理程度差距较大。设备发生故障、操作不规范、操作人员未经培训等是造成灭菌不合格的主要原因。结论医疗机构使用中压力蒸汽灭菌器灭菌合格率不高，加强对压力蒸汽灭菌器进货索证管理，规范操作，加大监管力度是提高压力蒸汽灭菌器灭菌效果的关键。
