The result showed there existed significant differences among families in seedling growth, dry matter accumulation, leaf shape as well as root parameters at high and low nitrogen levels. Remarkable reduction in seedling height, dry matter accumulation, leaf and root parameters were observed under low nitrogen stress, whereas larger proportion of photosynthesis production was allocated into roots to promote nitrogen absorption. Family variation in seeding growth, leaf and root parameters were increased under low nitrogen stress in comparison with high nitrogen level, which would be benefit to discriminate superior L. chinense families with high nitrogen efficiency. Nitrogen efficiency of different L.

结果表明：不同氮素水平下，马褂木苗的生长、干物质积累、叶片和根系等性状皆存在显著的家系遗传差异；低氮胁迫将显著抑制马褂木苗叶片发育和根系生长，影响苗高生长和干物质积累，但低氮素水平下生产的光合产物则较多地分配至地下根系部分以促进对氮素的吸收利用；与高氮处理比较，低氮胁迫加大了苗木生长、叶片和根系参数等家系遗传分化，有利于鉴别高氮效率的马褂木优良家系。

The study of natural fullerenes is a new area of across fullerene science and geological science. So far natural fullerenes have been found in shungite, fulgurite, carbonaceous conglomerates in impact crater, E/K boundary carbonrich clay rock layer, T/P boundary layer, dinosaur eggshell, coal, heavy crude oil, solid bitumen and socalled seminatural fullerenes in common soots, Chinese ink sticks, commercial char, et al., only with low concentrations.

天然富勒烯研究是富勒烯科学和地质科学相交叉的一个新兴研究领域，迄今为止已在桑加岩、闪电熔岩、陨石撞击坑中的含碳质角砾岩、古近系/白垩系地层界线的含碳粘土岩、三叠系/二叠系界线岩石、恐龙蛋壳、煤、重质油、固体沥青以及半天然的烟灰、木炭、书墨等物质中检测到富勒烯的存在，但含量很低。

The sandstone bodies of this sedimentary system are buried in shallow position and in good quality of porosity and permeability.Shengbei structure zone and its south flank are the main position for sandstone and available for the north pinch out subtle traps development.Combined the background of upheaval in sag and cling to the strike-...

根据胜北洼中隆良好的古构造背景，结合胜北3、4号南北向平移断层沟通中、下侏罗统水西沟群煤系地层和中侏罗统七克台组湖相泥岩烃源岩系等情况，认为胜北洼陷白垩系是浅层次生岩性油气藏勘探的有利地区。

Modern vessel power technology advance with vessel axle department a main research object, study structure characteristic, main technology, economy and performance index of its motive equipment; Advance axle department stable state and trends of device cooperate with the characteristic; Economy and improving

课程简介：现代舰船动力技术以舰船推进轴系为主要研究对象，研究其动力装置的结构特点、主要技术、经济及性能指标；推进轴系装置的稳态和动态配合特性；热力系统的经济性和提高装置经济性的有关措施；推进轴系振动的原理及减振措施；舰船动力装置的可靠性分析等各方面内容，以增加对现代舰船动力技术知识的了解。

The pectin esterase gene and amino acid permease gene abundantly expressed in floral buds of NCa CMS while pectin esterase gene showed no transcript either in young leaves of NCa CMS or in the two tissues of maintainer line, and amino acid permease gene slightly expressed in the corresponding tissues.

结果表明，果胶甲酯酶基因和氨基酸通透酶基因都在不育系花蕾中大量表达，果胶甲酯酶基因在不育系叶片、保持系的花蕾、叶片中都没有检测到；而氨基酸通透酶基因有微量表达。

The running quality of the wind tunnel power shaft system has a decisive influence on the efficiency and performance. With increase of the runtime of the shafting, rotor parts have inevitable mass eccentricity, which obviously strengthens the coupling function of torsional and bending vibration.

风洞动力轴系的运行品质对风洞的效率和性能有决定性的影响，随着轴系在役运行时间的增加，转动部分多数会有质量偏心现象出现，这使得轴系的扭转振动与弯曲振动的耦合作用明显增强。

We made all-round serological tests to the two RhD-- individuals,including identification of blood group、Coombs test、antibody screening and identification、antibody titer and HDN test,together with investigation of genealogical blood group to all family members by classic hemagglutination methods.

我们采用经典的血细胞凝集法，对2个体进行了血型血清学检测，包括血型鉴定、抗人球蛋白试验、抗体筛选与鉴定、抗体效价检测与新生儿溶血病检测，并对两个家系所有家系成员进行家系血型调查。

Knight of the reasons may be no conflict between the three-line, a matter for each stem, and the Master of the three-line have one thing in common - all three grades PK.

原因可能是骑士的三系之间没冲突，各有各的事干，而法师的三系都有一个共同点-三系都能PK。

The other bonus that the C200K enjoying is its steering department. It is different from most European cars that there would be sufficient road information feedback to the driver. The driver can make a good judgment on how he wants to drive the car. Just 2.7 turns lock to lock and 10.8 meters of turning circle; this setting reveals the enormous effort in making the C-class as an enjoyable car to drive but at the same time with a lot of luxurious appointments. Obviously, the C-class has evolved from just an expensive sedan into something representing the come back of the oldest car making in the world.

另一个C系的优点是它的转向部门，它与其他欧洲汽车是它有足够的道路资讯以以传递予驾驶者，因而，驾驶者可以因而作出合适的判断以协助它的驾驶需要，它的回转只是2.7手軚，10.8公呎的回转直径，因而，可以令C系成为一辆可以令驾驶者享受的豪华驾驶工具，明显地，C系脱离了只是名贵的汽车称号，而它的娇人成绩使平治-世上最资深的汽车公司可再次获得殿堂级的显赫地位。
