The main reason why quarter-sawn board of Birch had smaller dry compressing shear strength than flat-sawn board of Birch in normal conditions was that Birch had different shear strength to the grain between quarter-sawn board and flat-sawn board. Meanwhile xylary rays in flat-sawn board were transversely cut and left a lot of pores in the flat-sawn board, so adhesive can enter these pores and turn into adhesive nail. While these pores provided a kind of tunnel for water, so cause this phenomenon that wet compressing shear strength of flat-sawn board of Birch was smaller than that of quarter-sawn board of Birch. The possible reason why quarter-sawn board of Oak had greater dry compressing shear strength than flat-sawn board of Oak in normal conditions was that ratio of springwood on quarter-sawn board and flat-sawn board was different.
造成柞木径切板的常态压缩剪切强度比弦切板的常态压缩剪切强度大的主要原因是,在径切板和弦切板上早材胶接的比例不同,径切板的胶合强度试件上早材胶接的比例相对少,而弦切板的胶合强度试件上早材胶接的比例比径切板的胶合强度试件上早材胶接的比例相对大,由于早晚材胶接过程中强度决定于早材,这部分胶接强度比较低,这就使得柞木径切板的常态压缩剪切强度比弦切板的大;同时在柞木弦径面胶接过程中由于实际胶接面积的不同也能造成弦径面上API胶粘剂与之形成的化学键的数量不同,这也是造成柞木径切板的常态压缩剪切强度比弦切板的大的原因之一。

Studies showed that there were two typical combinations of the facies in the filling sedimentary sequence of the epicontinental basin, wherein one was the depositional diastem developed between the facies, which was a discontinuous combination of the depositional facies with continuous time sequence, namely the exposed sediments, the tidal flat swamp and the peat swamp, and the shallow marine sediments appeared from bottom to top; and the other was the continuous sequence with gradually evolved sedimentary environment, in which it was a continuous process that the tidal flat swamp turned gradually into the peat swamp.
研究表明:陆表海盆地充填沉积序列中有两种较为典型的相组合,一是相与相间发育沉积间断面,为不连续沉积相组合,但在时间序列上是连续的,即自下而上依次为暴露沉积、潮坪沼泽及泥炭沼泽、浅海沉积;第二种序列是连续相序,盆地的环境演化是渐变的,潮坪沼泽化逐渐泥炭沼泽化是一个连续过程。

Instead of calling on some scholar, I paid many a visit to particular trees, of kinds which are rare in this neighborhood, standing far away in the middle of some pasture, or in the depths of a wood or swamp, or on a hilltop; such as the black birch, of which we have some handsome specimens two feet in diameter; its cousin, the yellow birch, with its loose golden vest, perfumed like the first; the beech, which has so neat a bole and beautifully lichen-painted, perfect in all its details, of which, excepting scattered specimens, I know but one small grove of sizable trees left in the township, supposed by some to have been planted by the pigeons that were once baited with beechnuts near by; it is worth the while to see the silver grain sparkle when you split this wood; the bass; the hornbeam; the Celtis occidentalis, or false elm, of which we have but one well-grown;some taller mast of a pine, a shingle tree, or a more perfect hemlock than usual, standing like a pagoda in the midst of the woods; and many others I could mention.
我并没有去访问哪个学者,我访问了一棵棵树,访问了在附近一带也是稀有的林木,它们或远远地耸立在牧场的中央,或长在森林、沼泽的深处,或在小山的顶上;譬如黑桦木,我就看到一些好标本,直径有两英尺:还有它们的表亲黄桦木,宽弛地穿着金袍,像前述的那种一样地散发香味,又如山毛榉,有这样清洁的树干,美丽地绘着苔藓之色,处处美妙呵,除了一些散在各地的样本,在这乡镇一带,我只知道有一个这样的小小的林子,树身已相当大了,据说还是一些被附近山毛榉的果实吸引来的鸽子播下的种子;当你劈开树木的时候,银色的细粒网闪发光,真值得鉴赏;还有,椴树,角树;还有学名为Celtis occidenta lis的假榆树,那就只有一棵是长得好的;还有,可以作挺拔的桅杆用的高高的松树,以及作木瓦用的树;还有比一般松树更美妙的我们的铁杉,像一座宝塔一样矗立在森林中;还有我能提出的许多别的树。

In measurements of a day,generallyspeaking,the photosynthesis of birch in mesophytic habitat is better than that in xerophytichabitat(peak values are 12.8,10.33μmolCO2m-2s-1 respectively);that of sexual birch inmesophytic habitat is better than that of clone birch(peak values are 9.87,6.71μmolCO2m-2s-1respectively);that of young tree is better than that of seedling(peak values are12.37,10.05μmolCO2m-2s-1 respectively).
在一天中的各个时刻,总体说来,中生生境生长的白桦光合作用超过旱生生境生长的白桦光合作用(净光合速率峰值分别为12.8、10.33μmolCO2m-2s-1);白桦幼树的光合作用超过白桦幼苗(净光合速率峰值分别为12.37、10.05μmolCO2m-2s-1);中生生境有性白桦的光合作用超过无性白桦的光合作用(净光合速率峰值分别为9.87μmolCO2m-2s-1、6.71μmolCO2m-2s-1)。

The results revealed that nine of the fourteen Y-specific markers cannot be used for investigating the swamp buffalo Y chromosome genetic diversity because of the reasons specified below: three microsatellites markers (INRA008, UMN0103 and UMN0504) were single allele and monomorphism, three (UMN1113, UMN0304 and BC1.2) indicated three alleles respectively but mornomorphism, and the other three (UMN0920, UMN0307 and UMN3008) showed irregular ladder-like bands. Only the remaining five microsatellites (INRA124, INRA189, BM861, PBR1F1 and UMN2001) indicated polymorphisms, and thus can be applied to study the swamp buffalo Y chromosome genetic diversity.
结果表明,3个标记(INRA008,UMN0103和UMN0504)只有1个等位基因,表现为单态;3个标记(UMN1113,UMN0304和BC1.2)均为3个等位基因,但呈单态;3个标记(UMN0920,UMN0307和UMN3008)呈现无规律的梯状条带,所以这9个标记都不适用于水牛的Y染色体遗传多样性研究;只有5个标记(INRA124,INRA189,BM861,PBR1F1和UMN2001)具有多态性,表明适用于水牛的Y染色体遗传多样性研究。

Field investigation and analyses of the grain size, geochemical, stable carbon isotope etc climate proxies all indicate that this region, in about 14000aBP, u nderwent the expansion of the swamp. Subsequently, the swamp, because of aridity , began to decrease in area, and even disappeared. This process was followed by an immediate flooding period. The region, after the Younger Dryas cooling event (108000~10200aBP), came into the warming period of the Holocene, and then clima te in the region fluctuated subsequently.
张强通过区域地貌调查及对南京浦镇林峰桥剖面沉积物进行粒度、地球化学和稳定碳同位素等环境替代指标的分析研究,结果表明:本区在14000aBP左右先后经历了沼泽扩张期,此后气候变干,沼泽开始退缩,直至消失,在经过了长时间的沉积间断后又经历一次洪水泛滥期。

Because of a high groundwater level and a strong erosion action, the coal formed in a low peat swamp is great in gelatification index and in groundwa ter index, which are in a negative correlation to the ratio of clean coal recove ry. While for the high peat swamp, IG and IGW are small, corresponding to a high ratio of clean coal recovery.
低位泥炭沼泽由于潜水位较高,水流对泥炭沼泽表面的改造和冲刷作用较强,形成的煤层具有较高的凝胶化指数和地下水流动指数,并且与精煤产率呈负相关,煤中粘土矿物和黄铁矿难以洗选;高位泥炭沼泽形成的煤层具有较低的凝胶化指数和地下水流动指数,泥炭积累速度较快,其精煤的产率较高。
