The phenolic acid content of litter was significantly reduced with the decomposition time prolonging, and the releasing quantity of phenolic acid was the highest at the tenth day. The amounts of soil Aerobic azotobacter, Ammonifier and Aerobic cellulose-decomposer and the soil chemical properties such as pH, phenolic acid content, NH+4-N and available phosphorus were significantly affected by the litter aqueous extract of four decomposition stages.
凋落物分解的60 d中,凋落物残留量在前30 d内变化最大,30 d后无显著变化;凋落物中酚酸含量随分解时间的延长,呈显著降低的趋势,且在分解10 d时,酚酸释放量最大。4个分解动态的凋落物浸提液显著地改变了土壤好气性自生固氮菌、氨化细菌、好气性纤维素分解菌的数量和土壤pH值、酚酸含量、铵态氮、有效磷等化学性质。

In this paper, firstly we researched the relationships of the communicating distanceand the channel characteristic, the effect of the multiple scattering to the laserpropagation, the requirement of the laser communication to the ATP system and theway to determine the angular dispersion and receive field of view. It is proved that inlight haze weather, letting the input and output laser\'s wavelength are diferrent witheach other, after passing by the filter, it can avoid backward scattering effectually andfor the communication within 15km, the influence of the multiple scattering inatmosphere can be ignored.
论文对通信距离与信道特性、多次散射对光传输的影响、无线激光通信对ATP带宽的需求以及光束发散角和接收视场角等重要系统性能参数和指标进行了分析和研究,证明了在轻霾天气状态下,使系统中两终端发送的激光束波长各不相同,经过光束滤波,可以有效地消除后向散射干扰;在15km的通信距离范围内,大气中的多次散射对无线激光通信光传输的影响可以忽略。

She was particularly fond of animals, and, besides her canary, whose cage hung on a nail in the massive wall of the keep by day, to the great annoyance of prisoners who relished an after-dinner nap, and was shrouded in an antimacassar on the parlour table at night, she kept several piebald mice and a restless revolving squirrel.
她特别喜欢动物,养着一只金丝雀,鸟笼子每天就挂在厚厚的城堡墙上一只钉子上。鸟的鸣唱,吵得那些想在午饭后打个盹儿的犯人苦恼不堪。夜晚,鸟笼就用布罩罩着,放在厅里的桌子上。她还养着几只花斑鼠,和一只不停地转着圈儿的松鼠。

Descended from a long line of New England ministers, Emerson, finding himself fettered by even the most liberal ministry of his day, gently yet audaciously stepped down from the pulpit and, with little or no modification in his interests or utterances, became the greatest lay preacher of his time.
出生于新英格兰牧师家庭的爱默生,在发现他竟然被自己认为最自由的牧师职业所束缚后,大胆而平和地从讲坛中退了出来,并且在自己的兴趣和说话方式丝毫没有改变的情况下,成为了他那时期最伟大的传道员。

Based on the petrological and geochronological study of metamorphic complexes from the Grove Mountains, the following conclusions are reached.(1)Exsolution texture is widely found in clinopyroxene in mafic granulites. A peak metamorphic temperature of 850 C was obtained from the reintegrated compositions of exsolved clinopyroxene. The preservation of augite megacrysts suggests a single episode of high-grade metamorphism for the Grove Mountains.(2)The compositional comparison of garnet from pegmatites with that from country rocks demonstrates that garnet in pegmatites is of xenocryst origin, and late amphibolite facies metamorphism does not occur in this area.(3)The Pan-African charnockite and post-tectonic sheet-like granite were first recognized in East Antarctica. Their occurrences suggest a collisional orogeny during the Pan-African time.(4)The SHRIMP U-Pb zircon dating on various rock types indicates that the major metamorphism in the Grove Mountains occurs at c. 550 Ma, and the tectonothermal evolution terminated at c. 500 Ma. The Grenvillian granulite facies metamorphism did not develop in the studied area.(5)The Prydz belt, the second Pan-African suture within the Gondwana suppercontinent, was further comfirmed based on this study. The Gondwana suppercontinent was not formed by the simply juxtaposition of East and West Gondwana, but by the collision of several blocks during the Pan-African time.
本项目通过格罗夫山地区高级变质杂岩的变质岩石学和同位素年代学研究,获得如下重要认识:(1)发现辉石出溶结构,由此获得峰期变质温度为850 C,并根据火成普通辉石的识别确定该区只存在单相麻粒岩相变质;(2)通过伟晶岩中石榴石斑晶与围岩中石榴石的对比研究提出了石榴石的捕虏晶成因,进而确定该区不存在晚期角闪岩相变质作用;(3)在东南极首次识别出泛非期紫苏花岗岩和后构造层状花岗岩,为泛非构造热事件的碰撞造山成因提供了重要佐证;(4)对不同岩石类型的锆石SHRIMP定年精确地限定了格罗夫山地区主期变质作用发生于泛非期,~550 Ma,热事件结束于~500 Ma,年代学数据没有揭示在该区存在格林威尔期麻粒岩相变质作用的迹象;(5)进一步确认了东南极内部普里兹带的存在,它属于冈瓦纳超大陆内部的第二条泛非期缝合带,据此认为冈瓦纳超大陆并不是由东、西冈瓦纳陆块的简单拼合而成,而是多个不同块体拼合的结果。

To avoid or reduce re-analysis, we derived the augmentative matrix variation only in summation of the previous matrices time the outside-perturbed parameters by decomposing the element stiffness and mass matrix. The implicit function of amplitude about design variables such as cross-areas and lengths is changed into simplistic function about the perturbed parameters of design variables. Several methods for determining the value of perturbed parameters are detailed.
为避免或减少重分析,将有限元单元阵进行了分解变换组装,使振幅与设计变量如截面面积、长度的复杂隐函数关系转化为对设计变量摄动参数的显式关系,进而将设计变量摄动参数提取在分解后的几个常数刚度阵、质量阵之外,避免了在迭代求解过程中重组刚度阵与质量阵,较快地获得问题的解。

Adjustments of Second-hand housing policy reduce the deal cost, boosting buyers' expectations; In addition, such change may increase the liquidity of housing, which will speed up investment in new housing and shops. However, the price continue to drop, especially when the new year is coming, more shop investors keep waiting and seeing due to the financial crisis, macro news. Basing on the demand point of view, some demand for living improvement delay the bargain, so did demand for investment due to bad profit-making. As a result, the demand is difficult to start up, while the supply funds is not sufficient, therefore such commercial real estate enterprises will be out of the market due to their inability to meet the finance crisis. Under competitive pressures, the developers will pay more attention to products quality and products differentiation with a view to compete in the market to get a dominant position.
二手房政策的调整降低了购房者的购房成本,刺激了购房期望;另外,二手房政策的改变可能会增加房源的流动性,这样也会加速新房的销售,商铺投资逐渐活跃,但价格表现却成下行趋势,尤其是年关临近,在金融危机面前,商铺投资者多持币观望,从需求者的角度讲,部分改善型需求和投资型需求的购买行为将向后推迟,炒房者将因投机能力下降而不同程度地退出市场,另外,需求难以启动,供给方资金链紧张,部分自有资金不充裕的商业地产企业将面临因无力融资而退出市场的风险,企业因竞争压力大,将更加注重开发产品的品质,提供差异化的产品,以期在市场竞争中占得优势地位。

Named after the 19th century German chancellor Otto von Bismarck, Bismarck's fame came from the Battle of the Denmark Strait in which the flagship and pride of the British Royal Navy, the battle cruiser HMS Hood, was sunk in May 1941, from Churchill's subsequent order to "Sink the Bismarck", and from the relentless pursuit by the Royal Navy which ended with her loss only three days later.
俾斯麦"的赫赫大名来自于她在1941年5月丹麦海峡之战一举击沉皇家海军的旗舰——"胡德"号战列巡洋舰,来自于英国首先丘吉尔随后发出的"击沉俾斯麦的铁命令,来自于她被英国皇家海军坚韧不懈地追击在处女航仅仅三天后就被击沉。
