云南诗人普荷的休闲思想与休闲人生

云南唐氏家族诗人普荷的诗文所表现出来的思想意识,与现代休闲美学理论颇有契合之处。普荷具有不同世俗的休闲观念和休闲取向。他的休闲工夫着重心志调节的顺情与复性两个方面,并在境域取舍方面引导人们走向栖隐之境和游览山水之境;他的休闲境界既遁世又谐世,既安贫乐道甘于寂寞,又圆融通达与人同乐,并具有某种程度的超越。他的这些休闲观念与实践对构建当前休闲时代与和谐社会具有一定的正面意义。

丹青狂笔豪泄禅韵——谒“云南八大”担当之画风

担当的艺术成就经过历史的公证检验,文人骚客数百年的褒贬后,其尊名才得与明末清初中国美术史上伟大画家朱耷,石涛相提并论。从而海宇驰誉,金碧有光矣！谒《担当书画集》、《(?)园集》、《拈花集》、《撅庵草》等,深为担当“诗、书、画”三绝而倾倒,其中尤为青睐他的绘画。然而为之遗憾的是,中国诸画典里未列上这位大画家的名字,大概这与他深居西南边陲有关吧?若当时他亦显居中原的话,会有人为他树碑立传的。尽管他的名字未录进辞典,其艺术成就是不可抹灭的,被誉为“云南八大”可谓选准了词位,是名符其实的。

傅山绘画的另类特征

文人画是明清绘画的主流,产生了许多优秀的画家,因此也形成了不同的绘画流派。尽管如此,仍有一些自成体系者,诸如南方的戴本孝、普荷,北方的王铎、傅山等人,他们皆以自己独特的绘画面貌,呈现在画史之上。

Analytical solution to one-dimensional consolidation in unsaturated soils under sinusoidal cyclic loading

An analytical solution was presented to the unsaturated soil with a finite thickness under confinement in the lateral direction and sinusoidal cyclic loading in the vertical direction based on Fredlund's one-dimensional consolidation equation for unsaturated soil. The transfer relationship between the state vectors at the top surface and any depth was gained by applying the Laplace transform and Cayley-Hamilton mathematical methods to the governing equations of water and air, Darcy's law and Fick's law. The excess pore-air and pore-water pressures and settlement in the Laplace-transformed domain were obtained by using the Laplace transform with the initial and boundary conditions. The analytical solutions of the excess pore-air and pore-water pressures at any depth and settlement were obtained in the time domain by performing the inverse Laplace transforms. A typical example illustrates the consolidation characteristics of unsaturated soil under sinusoidal loading from analytical results. Finally, comparisons between the analytical solutions and results of the numerical method indicate that the analytical solution is correct.

Dynamic response of cylindrical cavity to anti-plane impact load by using analytical approach

The transient response of an unlimited cylindrical cavity buried in the infinite elastic soil subjected to an anti-plane impact load along the cavern axis direction was studied.Using Laplace transform combining with contour integral of the Laplace inverse transform specifically,the general analytical expressions of the soil displacement and stress are obtained in the time domain,respectively.And the numerical solutions of the problem computed by analytical expressions are presented.In the time domain,the dynamic responses of the infinite elastic soil are analyzed,and the calculation results are compared with those from numerical inversion proposed by Durbin and the static results.One observes good agreement between analytical and numerical inversion results,lending the further support to the method presented.Finally,some valuable shear wave propagation laws are gained: the displacement of the soil remains zero before the wave arrival,and after the shear wave arrival,the stress and the displacement at this point increase abruptly,then reduce and tend to the static value gradually at last.The wave attenuates along the radial,therefore the farther the wave is from the source,the smaller the stress and the displacement are,and the stress and the displacement are just functions of the radial distance from the axis.

Effect of captopril on myocardial energy metabolism in chronic pressure overload rats

Objective To investigate the effects of captopril on cardiac function and levels of energy-rich phosphates in pressure overload induced left ventricular hypertrophy rats. Methods One hundred and twenty SD rats were randomly divided into three groups： sham operation group （SH group, n=40）,coarctation of abdominal aorta group （CAA group, n=40） and captopril treatment lmg~ 100g1 ~ d-1） group （CAP group, n=40）. Left ventricular end-diastolic pressure （LVEDP）, left venh-icular mass index （LVMI）, levels of energy-rich phosphates and morphological changes of the myocardial mitochondria were compared at the 62 and 82 week after operation. Results At 62 week, in CAA group, LVMI and LVEDP were increased and _ dp/dtmax was decreased, while ATP and ADP were decreased and AMP was increased （P〈0.01）. These changes were much obvious at 8th week （P〈0.01）. Compared with those of CAA group, the parameters of heart function and energy-rich phosphates （ATP, ADP, AMP, TAN） in CAP group were improved significantly（P〈0.01） at the 6th and 8th week. In CAP group, the parameters of heart function and energy-rich phosphates （ADP, AMP, TAN） were much better at 8~ week than those at 6th week. The morphological change of mitochondria was less in CAP group than that in CAA group. Conclusion Captopril significantly improves myocardial energy metabolism in pressure overload rats and protects the function of myocardial mitochondria

诗僧担当的书法艺术

一明末清初,是中国社会大动荡的时代。自万历末年以来,明王朝在政治上日益腐败,宦官专权,大臣昏庸无能,对老百姓变本加厉的压榨剥削,激化了阶级矛盾,导致波澜壮阔的农民起义,最终覆灭了朱明王朝。不幸的是以李自成为代表的农民起义军,未能巩固已经取得的政权,被关外满族统治者与吴三桂等合流,乘机掠夺了胜利果实,在中原建立起清王朝,把广大人民重新置於残酷压迫统治之下。在这种形势下,当时知识分子的出路只有两条:一是投靠依附新的统治者,充当顺民,以保住往昔的利益;一是消极抵抗,采取不合作的态度,或浪迹江湖,或遁入空门。另外少数人则打起抗清扶明的旗帜,纠集残余武装力量,与清军相周旋。但终因清军势力过於强大,被陆续消灭干净,只有占据孤岛的郑成功和辗转西南边陲的永历政权撑持了较长时间,而最终还是未能光复旧国。

名画赏析

《慈母手中线》罗中立1983年油画110cm×78cm溪边老树下,年轻的母亲专注地做着针线活,身旁的婴儿在斑驳的光影中酣睡,为了让孩子睡得香甜,母亲巧妙地用脚套住摇篮上的绳索,不时地摇晃着摇篮,于无声中传递出母亲的慈爱与守护。画家在人物形态及场景描绘中追求口语化的直白,母亲粗壮的手臂透出一种健康的美,还原了人性真实、自然的本质。老树及河边的青绿采用了点彩和类似于石壁画的色彩肌理语言,使人物与背景紧密交织、协调统一。

劳动最美

前面是绿油油的庄稼,再前面还是绿油油的庄稼,走在这样的原野,你一定在微笑,走在这样的大地上,你心里一定感觉很踏实。这就是劳动与创造之美,给予你的那份情不自禁的感动。我以为对爱的抒写,不是一件简单的事情,对大地爱的抒写将更加艰难。当我走在色彩缤纷的田野,看到无垠大地与人们劳动相融合的和谐画面时,才知道爱的表达如此简单。无须用心的矫揉造作。
