查询词典 s

A highly in uential source of this suspicion is Barry Stroud, who in his article 'Transcendental Arguments' suggested that for any claim concerning the necessary condition S,"the sceptic can always very plausibly insist that it is enough we believe that S is true, or it looks for all the world as if it is, but that S needn'tactually be true"(Stroud 2000: 24).3 So, in the case of the problem of the external world, for example, the concern is that no argument can be constructed to show that there must actually be an external world, but just that there must appear to us to be one, or that we must believe there to be one.

斯特劳德在《先验论证》一文中指出，任何涉及必要条件S的断言都会受到怀疑论者这样的反驳：我们确实要相信S是真的，或者说在所有的世界都是这样，但是，S不需要真正地为真。所以，在外在世界问题上，并没有一个论证可以给出证明，说外在世界必须真正实际地存在，而我们只能说，必须有一个外在世界向我们显现，或我们必须相信有一个外在世界。

Capitol's Vintage Collections CD is the best single-disc overview of Jackson's most essential rockabilly and country recordings for Capitol from 1956 through 1961, surveying Jackson in a variety of modes, from full-throttle rock ("Let's Have a Party," originally recorded by Elvis Presley and featured in the film Loving You) to rockabilly to traditional country (the weeper "Why I'm Walkin'" gets over via a vocal imbued with the profound sadness so characteristic of Patsy Cline's great tearjerkers).

Capitol's Vintage Collections CD收集了她1956年-1961年为Capitol录制的最牛B的摇滚比利和乡村单曲，展现了她在音乐方面的多面性，从拥有能杀人般力量的摇滚比利(Let's Have a Party，原始版本为猫王在电影LOVING YOU中的演唱)到传统的乡村歌曲Why I'm Walkin'，声音里充满了Patsy Cline般催人泪下的伤感

Here we have discussed the Casimir force of Maxwell-Chern-Simons gauge field and obtained the new results, namely the contribution of force of M-C-S gauge field to the Casimir force zero temperature, the radiative correction to the Casimir force of M-C-S gauge field at zero temperature and Casimir force of M-C-S gauge field at finite temperature between two parallel ideal conducting wires.

Is a small freshwater alga suitable to live in an environment where both water temperature and light intensity is relative low. The optimum water temperature of 15℃ and the optimum light intensity of 35μmol/m^2s~45μmol/m^2 s are needed for photosynthesis of Batrachospermum longipedicellatum.

其光合作用的最适水温为15℃，光合作用的适宜光强为30μmol/平方公尺s~50μmol/平方公尺s，最适光强度为35μmol/平方公尺s~45μmol/平方公尺s，40μmol/平方公尺s光合速率最高峰，为其饱和光强。

Results show that the G and S units of wheat original lignin consist of 25. 35mol% uncondensed G units, 17. 60mol% uncondensed S units and 37. 05mol% condensed G units. The dissolution rate of S units is faster than that of G units in SFP—AQ and AP—AQ cooking. The residual lignin in SFP pulp has smaller amount of DPM structure and thus has better bleachability compared with those in AP pulp.

研究结果表明麦草原本木素G和S单元由25.35mol％的非缩聚G单元，17.60mol％非缩聚S单元和57.05mol％的缩聚G单元组成；在SFP—AQ和AP—AQ蒸煮中，木素S单元的溶出速率大于G单元的溶出速率；与AP浆比较，SFP浆中残余木素含有较少的DPM结构，从而具有较好的可漂性能。

If G is a {2K_1+K_2, C_4}-free graph, we show thatifα＞3 then G is a split graph, and ifα=3 then for any independentset S of cardinality 3, G-S is a chordal graph or G-S?

如果图G不含与4-圈和2K_1+K_2同构的导出子图，我们证明了如果α＞3，那么G是一个split图；如果α=3，那么对于G的任一个有三个元素的独立集S，G-S是一个弦图或者G-S？

The main characteristics include: the quiet Sun corona has a rapid response to the flare heating, within 2 second the corona temperature increases nearly one order of magnitude, but later such increase becomes very slowly; the downward velocity at early stage of impulsive phase is too small to be negnected; chromospheric evaporation made by conduction shows some intensely, the maximum evaporated velocity may be as large as 1000 km/s; the chromospheric condensation appears just when the chromospheric evaporation takes place and its place always coincide with that of transition region in the early stage; the maximum of chromospheric condensation occurs also in the early stage of impulsive phase, at which the density in condensation may be larger two order of magnitude than that of surround and the downward velocity may be as large as 100 km/s; after the maximum of chromospheric condensation, its strongth decreases gradually but its width becomes greater with time and have a tendency to transport into deep chromosphere; the front of chromospheric condensation heats atmosphere obviously and the temperature in the chromospheric condensation is higher than the original case; the downware velocity of transition region may be greater than 100 km/s at the early stage; when the evaporated material collide at the top of loop, the densityand the presure there increase rapidly, which result in the formation of a shock wave; and so on.

在改善色球辐射损失和精确分辨过渡区的基础上，通过联立求解连续性方程、动量方程和能量方程，构造了一维磁限制性耀斑环在热沉积作用下的大气动力学模型，获得了耀斑热模型下脉冲相早期较为细致的大气演化理论图象，其主要特征是：耀斑对宁静日冕的加热相当迅速，仅2秒钟日冕温度增加即达一个量级，之后日冕温度增加缓慢；脉冲相早期日冕向下速度很小，几乎可以忽略，热传导驱动色球蒸发，其过程较为激烈，蒸发极大速度可达到1000km/s；色球压缩区与色球蒸发几乎同时形成，且在早期其位置总是与过渡区位置重合；色球压缩极大发生在脉冲相早期，其时密度可高于周围约2个量级，向下速度可超过100km/s；色球压缩极大后，其强度逐渐减弱，但宽度明显增大，且渐渐脱离过渡区往色球传播；压缩区内物质温度要高于原先的大气温度；过渡区下降在脉冲相早期相当迅速，可超过100km/s；当蒸发物质在环顶高速相碰时，环顶的密度、压力迅速增大，且温度也有所增加，导致形成激波，其波面以每秒上百公里的速度自环顶向下传播；在脉冲相前期，日冕软x辐射对色球的加热作用可以忽略；等。
