极弱地

A positive correlation was found between the solar activity and NO3- concentration in recent 1500 years. A long-standing issue of the nature of the solar activity during the Maunder Minimum was solved. An about 36a cycle was found in the solar activity. Low solar activity and weak geomagnetic field were responsible for the 36Cl peak at about 37ka BP. Climate change recorded in this ice core lagged insolation about 4ka during the last glacial maximum, about 1ka during the last deglaciation, and nearly 0ka during the Holocene.δ18O record also suggests that the variation in temperature on the Tibetan Plateau had some similar features to that in both Northern and Southern Hemispheres during the last deglaciation to some extent, which indicate that the tropics maybe play an important role on global climate change.

揭示出近1500a来古里雅冰芯中NO3-浓度变化可以反映太阳活动的强弱变化；回答了长期争议的并直接关系到太阳发电机理论是否正确的Maunder极小期太阳活动特征问题；发现太阳活动可能存在36a左右的周期；证实了37kaBP左右古里雅冰芯记录中宇宙成因同位素36Cl含量峰值的存在，指出这一时期的宇宙成因同位素峰值事件具有全球性，弱的太阳活动和弱的地磁场是这一事件发生的原因所在；揭示出古里雅冰芯记录到的"8.2ka BP事件"，认为这一全球性事件发生的主要原因与弱的热盐环流和弱的太阳活动有关；发现古里雅冰芯记录的末次冰盛期和末次冰消期气候变化均在一定程度上滞后于太阳辐射变化，而全新世气候变化大致与太阳辐射变化同步；发现末次冰消期高原地区气候变化不仅具有北半球气候变化的某些特征，同时还具有南半球气候变化的某些特征，这说明热带地区可能对全球气候存在重要的影响。

A pianist's refinement of touch can be anticipated already from the opening bars of "Ondine" from "Gaspard de la Nuit" by Ravel and Ruei-Bin Chen was successful in his rendering of the triple pianissimo of the introductory chords constantly changing in tone colour, which in the beginning overlie the melody line in the bottom part; he presented the piece, which, in terms of sound language, is evocative of Debussy, with intensity in sustaining and increasing the tension: he painted "Le Gibet in sombre colours and demonstrated all nuances of a pianist's art of touch.

他成功地把这首曲开始的几组和弦，音色不断转变，在低音旋律之上显现极弱段。这首作品在音乐语言上令人联想到德布西，但陈瑞斌的演奏，表现出强烈的延续性和不断增强的紧张气氛。他把《绞台》髹上了灰暗的颜色，亦表现了钢琴家触键艺术的细致处理。拉威尔为诗人亚来奥。

Staccato simply didn't bother me and I was able to advance very rapidly, and I have found that after a half century of playing the clarinet that there are many times when you simply di not use the tongue on the reed to start a very pianissimo sound.....true.

断奏当时对我来说完全不成问题，我也就进步地飞快。而且，在累计了50多年的演奏经验之后，我发现，很多时候，你根本不会在开始吹奏一个极弱音头时用舌头。

For example, a pianissimo passage played only with the flesh will sound fuzzy and indistinct, yet the same dynamic shaped with the nail projects beautifully, even in a large hall - Sharon Isbin

举个例子：如果不留指甲演奏极弱的乐句，声音将会变得模糊不清。如果留指甲，同样的力度就可以优美地发音，即使在大音乐厅里。

Under a fixed model of chromospheric flare, we investigate the influences of Hα and CaIIK line profilles on various velocity distributions from semiempirical view. The results show that: Hα line is very sensitive to the velocity in upper chromosphere; the profile of CaIIK line have responses to velocity in any layer of chromosphere, but the degree of CaIIK line asymmetry is much weaker than that of Hα and can be ignored if velocity is as small as 10km/s; chromospheric condensation in lower part of transition region have strong influence on Hα line but contrary to CaIIK line, the typical characteristic of H line effected by chromospheric condensation in transition region is reversed blue asymmetry, i.e. the intensity of blue peak is stronger than that of red peak; the stronger the chromosphoric condensation is, the more obvious the Hα line asymmetry appears; and so on.

在确定的大气模型下，从半经验角度系统地研究了大气各个层次的速度场和运动结构对Hα和CaⅡK谱线轮廓的影响，得到；Hα线对色球上部速度场敏感，而对色球下部和温度极小区附近速度场不敏感；CaⅡK对整个色球速度场均有反应，但不对称性较Hα弱，且速度小于10km/s时不对称性很不明显；CaⅡK受过渡区色球凝聚的影响较弱，而Hα对色球凝聚十分敏感；色球凝聚影响Hα轮廓的典型特征是呈反转结构的兰不对称性，即兰峰强于红峰；色球凝聚越强，Hα不对称性也越显著：等。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
