Sometimes the neighbour's pigeons land on my windowledge Cooing softly Where the great poplar at the window has somehow grown beyond the fourth-floor roof They skim round its crown and back The sunlight on their fluffy feathers Alive day by day I keep coming indoors empty-handed And throwing book and jacket on the bed As the days hurry by I can bring scarcely anything home Even after days away Only you remain and the little room Living day by day We have grown used By an unspoken pact to the room's breadth A pair of pigeons cooing softly on the windowledge Which at many instants belong to us Day by day Dust that falls on book spines gradually yellows Perhaps it is otherwise That life, if it does, provides I know that the unwitting request is not excessive And that summer turns to autumn Perhaps fallen leaves will swirl after a night of rain It does not mean a return to green shade deep in sunlight A house-cleaning when leisure affords Feelings may come on latent even as Irrelevancies are spoken softly The instant when a first trembling on the lips teaches you happiness Lasts till the end of life A request always voiced unwittingly

有时候，邻家的鸽子落在我的窗台上咕咕地轻啼窗口的大杨树不知不觉间已高过了四层楼的屋顶它们轻绕那些树冠又飞回来阳光在蓬松的羽毛上那么温柔生命日复一日我往往空着手从街上回来把书和上衣掷在床上日子过得匆匆忙忙我时常不能带回来什么即使离家数日只留下你和这小小的屋子生活日复一日面对无声无息的默契我们已习惯了彼此间的宽容一对鸽子在窗台上咕咕地轻啼他们在许多瞬间属于我们日复一日灰尘落在书脊上渐渐变黄如果生活时时在给予那也许是另一回事我知道，那无意间提出的请求并不过份我知道，夏日正转向秋天也许一场夜雨过后就会落叶纷飞不是说再回到阳光下幽深的绿荫日子需要闲遐的时候把家收拾干净，即使轻声述说些无关紧要的事情感也会在其间潜潜走过当唇际间最初的战栗使你感知了幸福这一瞬已延伸到了生命的尽头而那些请求都是无意间说出的

CHAPTER VI WHO GUARDED HIS HOUSE FOR HIM Chinese The house in which he lived consisted, as we have said, of a ground floor, and one story above; three rooms on the ground floor, three chambers on the first, and an attic above.

六 他托谁看守他的房子英文他住的房子，我们已经说过，是一所只有一层楼的楼房，楼下三间，楼上三间，顶上一间气楼，后面有一个四分之一亩大的园子。

The results were as follow: At fine, cloudlet and cloud weather in rainy season,the mean value of CO 2 content varied in a range of 349 to 350ml/m\+3 at 2.8m above the canopy, 346 to 348ml/m\+3 at 0.8m above the canopy, 345 to 349ml/m\+3 at 16m inner the forest and 352 to 357ml/m\+3 at 5m above ground in the period from 9:00 to 18:00.The CO 2 content in rainy season was lower than that in dry season. At the same weather and space-time, CO 2 content in rainy season was higher than that of CO 2 in dry season at both day and night. According to the grads calculation, there were the CO 2 flux from atmosphere to canopy with 0.61×10 -6 and 0.71×10 -6kg/(m 2·s) during day time in dry and rainy seasons respectively.

采用梯度法及CI-301PS CO2系统，实现了海南尖峰岭热带山地雨林近冠层CO 2、微气象因子梯度观测研究，结果表明：雨季晴、晴间少云及多云天气，9：00～18：00CO 2浓度平均值分别在349～350ml/m3(冠上2.8m)、346～348ml/m3(冠上0.8m)、345～349ml/m3(林内16m)、352～357ml/m3(林内5m)，较旱季相应天气分别小14～17.5、10.1～23.7、1 6.4～35.7和18.1～36.1ml/m3；1：00～8：00，则雨季CO2浓度大于旱季；梯度浓度廓变量和实时动力计算反映出，8：00～18：00CO2通量由大气向林冠层，旱、雨季平均CO2通量分别为0.61×10-6kg/(m2·s和0.71×10-6kg/(m 2·s)，19：00通量甚微，20：00～7：00CO2通量则由林冠向大气，平均CO2通量分别为0.36×10-6kg/(m2·s)和0.32×10-6kg/(m2·s)；雨季昼夜大气流向冠层的净CO2通量是相应旱季的1.56倍。

Objectives: Being able to simultaneously express all genes of germline, endoderm, mesoderm and ectoderm, bone marrow mesenchymal stem Cells are considered to have the potential to differentiate to other tissues and cell lines.

目的 骨髓间充质干细胞(Mesenchymal Stem Cells，MSCs)能同时表达内胚层、中胚层和外胚层等所有三个胚层的基因，具有向其它细胞和组织多向分化的潜能。

Therefore the dispersion curves obtained in the field are primarily consisted of the first mode. For a heterogeneous elastic solid consisting of three homogeneous layers whose interlayer has low velocity, the phase velocity V〓 of the first mode will also close up to the Rayleigh wave velocity of the bottom layer when frequency f→OHz, but V〓 of the first mode will close up to the shear wave velocity of the interlayer when f→∞, and there is a cut-off frequency at high frequency region for the first mode and V〓 close up to the compressional velocity of interlayer when interlayer is liquid.

当三层固体介质中存在软夹层时，若f→OHz，则其基阶模式的相速度V〓→V〓（V〓为最底层介质的瑞利波速度）；若f→∞，其基阶模式V〓→V〓（V〓为中间层介质的横波速度）；若三层介质中存在液体夹层，当f→OHz时，基阶模式V〓→V〓，而基阶模式在高频段存在一个截止频率，截止频率处的瑞利波速度V〓→V〓；由此可判定，野外实测的相速度频散曲线不仅有基阶导波模式，同时还应有高阶导波模式波的存在，接收信号中存在模式间的跳跃，因此频散曲线会产生"之"字形现象。

Rather than on the more usual modern method of studying biological remains found in interglacial beds themselves interstratified within glacial deposits.

不471。是依据更为普遍的现代方法，472。去研究间冰层中所发现的生物残留物，而473。这些间冰层本身又在冰川沉积物发生间层化。

Based on the composite bounded reservoir model with two porous media, the Laplace solution of dimensionless pressure distribution under inner boundary condition (considering the wellbore storage and the skin effect) has been studied, and through analyzing the structures and interrelations of Laplace solution, the correlations with usual composite, two porous media and homogeneous reservoir pressure distribution have been found.

We measured morphological and physiological characteristics of C. asiatica in spring 2004 and 2005 at three levels: ramet population, clonal fragment and leaf. Environmental factors of different microsites were investigated again in September 2006. Important findings At the ramet population level, we observed no effect of habitat (forest edge vs. abandoned grassland slope).

The result would be used in tobacco breeding.4 SRAP technology is used to study the genetic differences among different types of tobacco, including flue-cured tobacco, oriental tobacco, maryland tobacco, burley tobacco, and air/sun cured tobacco, five pairs of primer combinations which can amplify characteristic bands has been screened. Among the five combinations, two of them (SF25*SR2 and SF3*SR26) can distinguish air-cured tobacco including maryland tobacco and Burley tobacco from the other cultivated forms; SF20*SR14 can distinguish sun cured tobacco including oriental tobacco and sun-cured tobacco; SF16*SR14 can distinguish flue-cured tobacco and air-cured tobacco, and SF22*SR14 can distinguish DBJ599 with specisl aroma and the other flue-cured tobacco.5 8 varieties , which represent the different types of tobacco, are divided into 3 groups. I: G-28, II:DBJ599、MD40、By21, III: Basma、Sumsun、XNS、QCT. The cluster analysis result es consistant with experience evatuation.6 Anorthogonal design was used to optimize a ILP-PCR system with 5 factors (DNA, Mg2+, dNTP, primer and Taq polymerase) at 4 levels.The result showed the optimized ILP-PCR system for Nicotiana tabacum L. was: 2uL10×PCRbuffer, 20ng template DNA, Mg2+ 2.0mmol/L, dNTP 150umol/L, primer 0.3umol/L, Taq DNA polymerase 1 U in a total of 20uL reactionsolution.
