弦乐四重奏则是由四件弦乐器——两把小提琴、一把中提琴和一把大提琴——组成的乐器演奏组合，它们的音色既统一又富于变化，以细腻的织体和精妙的韵味见长，而且四件乐器均具有强大的表现力，同时又符合西方音乐中四个声部的思维习惯，因此，这种组合成为室内乐中最具代表性的重奏形式，也成为作曲家表达最深刻和最个性化音乐思想的有效手段。文章分析室内乐与弦乐四重奏的基本内容及关系，讨论弦乐四重奏的发展概况，最后探讨了弦乐四重奏的"民族化"及未来发展趋势。

文化 徐锡台先生认为商周时期人们以一、五、六、七、八、九这六位奇偶数排列组合成二百一十六个单卦，四万六千六百五十六个重卦，二十七万九千九百三十六爻，而六十四卦是在秦汉时才出现、在商周时期是不存在的[15]。

There have been caught in Walden pickerel, one weighing seven pounds —— to say nothing of another which carried off a reel with great velocity, which the fisherman safely set down at eight pounds because he did not see him —— perch and pouts, some of each weighing over two pounds, shiners, chivins or roach, a very few breams, and a couple of eels, one weighing four pounds —— I am thus particular because the weight of a fish is commonly its only title to fame, and these are the only eels I have heard of here;——also, I have a faint recollection of a little fish some five inches long, with silvery sides and a greenish back, somewhat dace-like in its character, which I mention here chiefly to link my facts to fable.

在瓦尔登湖中，捉到过梭鱼，有一条重七磅，且不去说那另外的一条，用非常的速度把一卷钓丝拉走了，渔夫因为没有看到它，估计它稳稳当当有八磅的重量，此外，还捉到过鲈鱼，鳘鱼，有些重两磅，还有银鱼，鳊鱼（学名Leueiscus Pulchellus），极少量的鲤鱼，两条鳗鱼，有一条有四磅重，——我对于鱼的重量写得这样详细，因为它们的价值一般是根据重量来决定的，至于鳗鱼，除了这两条我就没有听说过另外的，——此外，我还隐约记得一条五英寸长的小鱼，两侧是银色的，背脊却呈青色，性质上近于鲦鱼，我提起这条鱼，主要是为了把事实和寓言连接起来。

Third, Evaluation criteria are inflexible and can not serve the aim of evaluating different projects with different characteristics, the evaluation index being unchangeably bound to papers, works, or scientific research projects.

通过对我国高校教师科研评价的研究发现存在如下问题：一是评价方法不完善，以定量评价为主；二是重形式轻实质，注重科研成果发表的刊物级别、获奖等级，并以是否&核心&、SCI、EI收录等形式代替实质；三是评价标准单一化，不管评价目的是否相同，均采用论文、著作及科研项目等源生指标作为评价标准；四是重数量轻质量，教师为了数量达标，不得不为凑数写文章。

The pollens of dehisced anthors of flowering P. polyphylla plants was slightly painted on the slide glass, the activities of P. polyphylla pollens were determined resp. by iodine-potassium iodide dyeing method (I2-KI), triphenyl tetrazolium chloride staining method, aceto carmine dyeing method and fluorescein diacetate method with a little improvement.

We believe that these know there are confusion and misunderstanding: the Han dynasty with six, the number one or two are actually composed of Yin and Yang Yao Yi Gua 64 hexagrams of the other kind of painting writing, it is not appropriate to "double-digit Gua" Moreover, he pre - avowed; so-called "10 digital hexagrams" If Mr.

已知崧泽文化中的数字卦虽然没有将二、三、四归并入一、六两数，但它们显然也不可能是徐先生所论&四万六千六百五十六个重卦，二十七万九千九百三十六爻&那种数字卦。

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