Meditations of evolution increasingly vaster: of the moon invisible in incipient lunation, approaching perigee: of the infinite lattiginous scintillating uncondensed milky way, discernible by daylight by an observer placed at the lower end of a cylindrical vertical shaft 5000 ft deep sunk from the surface towards the centre of the earth: of Sirius 10 lightyears (57,000,000,000,000 miles) distant and in volume 900 times the dimension of our planet: of Arcturus: of the precession of equinoxes: of Orion with belt and sextuple sun theta and nebula in which 100 of our solar systems could be contained: of moribund and of nascent new stars such as Nova in 1901: of our system plunging towards the constellation of Hercules: of the parallax or parallactic drift of socalled fixed stars, in reality evermoving wanderers from immeasurably remote eons to infinitely remote futures in comparison with which the years, threescore and ten, of allotted human life formed a parenthesis of infinitesimal brevity.

347关于宇宙日益扩大进化的冥想:新月期的月亮,即使在近地点也看不见。从地表向地轴挖掘纵深五千英尺的圆筒状垂直轴,一个观察者呆在轴底儿上,就连白昼也辨认得出那漫无止境、网络状、亮光闪闪、非凝结性的银河。天狼距地球十光年(五七、000、000、000、000英里);体积大于地球九百倍;大角;岁差运动;有着"猎户"腰带、六倍于太阳的"伐二"以及星云的猎户座,星云中能容纳我们的一百个太阳系;死去的和新生的星宿,例如一九0 一年的那颗"新星"我们的太阳系正朝着武仙座冲去;所谓恒星的视差或视差移动,也就是说,实际上恒星是在不断地从无限遥远的太古朝无限遥远的未来移动着。相形之下,人的寿命充其量才七十年,不过是无限短暂的一段插曲而已。

Based on the load transmission mechanism of space truss, and referenced theanalysis of test materials, a formula for calculating the bearing capacity of reinforcedconcrete compression strut is introduced. By using the theory of plastic hinge-line, anupper limit solution of bent bearing capacity for four-pile cap, which coincidesprecisely with the practical measurements, is obtained. By utilizing the reaction ofthe soil under cap and by basing on the method of plastic ultimate analysis, an upperlimit solution of punching shear bearing capacity for pile cap is acquired, which. coincides precisely with the practical measurements, and the formula is similar to thecode.A brief discuss on cooperative work of strip beam of foundation and single rankof piles is made. Separately considering the pile-cap and the pile-group, thencoupling their matrix of rigidity, the inner force of pile-cap is solved by the numericalmethod under some reasonable supposition. In comparison with other method, thecalculating results are exact, reliable and convenient in using. The method provides apowerful tQol fOr further analysis and research on this kind of structure.

Six experimental stages were designed in our procedure, those are:(1) metabolite recovery and tested sample preparation: the metabolites were recovered by Amberlite XAD-2 absorption, followed by MeOH elution and solvent concentration;(2) antioxidant detection and strain selection: samples were quantitatively analyzed by the inhibition effects on formation of lipid peroxides and TBARS to screen the strains able to produce antioxidants.

It is necessary to carry out a thorough study on pest control technology with DMDS, with an expectation of obtaining a new fumigant of methyl bromide alternative.2. Investigation of the toxicity of fumigation on adult and mixed stages of the three most tolerant insect species -- Sitophilus oryzae, Rhyzopertha dominica and Tribolium castaneum -- under a range of EtF、DMS and DMDS doses in a Flow-through Fumigation System shows that the FTFS procedure offers a constant concentration of fumigant with low CO2 concentrations and ensures that the fumigant toxicity is effectively not compromised by CO2. In comparison with chamber fumigation method, the toxicity data of EtF、DMS and DMDS obtained from this experiment is more accurate by using FTFS.

A multiplayer chip LC resonator was fabricated using planar inductor and parallel plate capacitor. Because lumped inductor has small Q value and there is stray parameter effect in high permittivity substrate, the Q value of chip LC resonator is not high. Resonators based on λ/4 stripline with end short circuited were designed and fabricated. Input and output pads, coupled to the stripline using gap-coupling capacitor, are in the same layer with the center conductive strip. This new structure is very convenient for manufacturing in comparison with the conventional structure.

采用间隙电容耦合结构实现的谐振频率为1.8GHz四分之一波长终端短路带状线单端口谐振器的Q值最大值为225,谐振频率为1GHz双端口谐振器的Q值为83,谐振频率和Q值与耦合间隙、带状线的厚度和耦合引线长度有关;二分之一波长带状线谐振器的Q值和四分之一波长相比较尺寸较大,由于导电带较长,造成金属的损耗增加,从而导致谐振器的Q值较低;带状线结构的谐振器频率调节困难,本文提出了改变接地端的宽度实现谐振频率的微调方法,可实现频率调节量约1.5%。

The finite element model included two types of main element: beam element for concrete and truss element for internal unbonded or external tendon. The end nodes of main elements were connected with internal constraints named MPC in ABAQUS. Spring elements with very large stiffness were set up at the place of the deviators of externally prestressed beams, or along the span with relatively little space of unbonded internally prestressed beams. The modified Riks method is utilized to trace the entire structural response of beams prestressed with unbonded tendon from zero to ultimate loads. The reliability of the analysis model is verified by analytical results of typical test beams in comparison with experimental ones.

The traditional algorithms of classification are no longer suitable because of the effect of the concept drift in data streaming. The research on fast and stable data mining systems with high accuracy has become more valuable in both theory and practice. The effect of low frequency concepts on time and space performance is studied and an LFCR algorithm is proposed in this paper, which reduces the low frequency concept with some mechanisms. The extensive experimental study shows that LFCR has improved performance in classification in comparison with RePro.

由于数据流中概念漂移现象的影响,使得传统的分类方法不再适用,因此研究快速、精确及稳定的数据流挖掘方法和系统具有较高的理论和应用价值;文章研究了基于频度的概念漂移中低频概念对分类时空性能的影响,提出了对其中的低频概念进行消减的算法,实验表明LFCR算法比RePro算法有更好的分类性能。
