Secondly, enrichment of 13C and 15N and their combination with NMR spectroscopy can help us study not only the dynamics of decomposition of organic materials but also the changes of their chemical structures during the turnover of the organic materials, which can provide more information in clarifying the C and N cycling and humification of the organic materials applied to soils.

本文根据已收集到的部分资料，对13C标记技术在土壤和植物营养中的应用情况作一简要综述，并在此基础上讨论了13C加富标记技术在研究植物光合作用、光合产物的去向以及标记秸杆在土壤中的分解等方面的应用及其注意点，旨在能为国内开展这方面的工作提供十分有用的参考

The FTIR spectrum showed that the ketone carbonyl groups of DAAM reacted with hydrazide groups of ADH to form hydrazone during film formation.TEM picture showed that the structures of particles were core and shell, and TGA curves indicated that the thermal stability of cured film decreased, which was attributed to the presence of C=N groups.

傅里叶红外光谱表明在涂膜形成过程中DAAM的酮羰基与ADH的酰肼基反应生成腙，TEM分析显示乳液的乳胶粒子呈核壳结构，TGA分析发现DAAM改性的PAE降低了涂膜的热稳定性。

The results also indicate that the Ph stability and the concentration of N exert a great influence on the growth of C reinhardtii- se and the acetic acid is the key substance for hydrogenase induction.

综合考虑两步法产氢对细胞生长周期和细胞密度的要求以及最终厌氧诱导获得的氢酶活性，最终选择seTA培养基作为莱茵衣藻- se 产氢用培养基。

Using the length of cells' growth cycle,the density of cells and the activity of induced hydrogenase as criteria,the optimal formulation of culture medium was obtained as seTA(se -Tris Acet) which contains acetic acid as C source,higher concentration of N and stronger pH buffer system based on the se formulation.

结果发现，培养基的pH和氮素的含量是影响莱茵衣藻生长的重要因素；而培养基中醋酸根的含量则有助于提高厌氧产氢过程中衣藻的氢酶活性，从而提高其产氢量。

In chapter 1, we introduce the definitions of area integral S_β and invariant g-function on unit sphere, and study their boundedness on BMO and non-isotropic Lipschitz spaces.

共分三章，第一章引进了C~n单位球面上的面积积分和不变g函数，研究它们在BMO空间以及non-isotropic Lipschitz空间上的有界性问题。

Methods Six cadaveric lumbar vertebrae were harvested and evaluated with dual-energy x-ray absorptiometry and quantitative computed tomography to assess bone mineral density. Matched, polyaxial pedicle screws were then randomly assigned by side and placed using the Magerl, Krag or caudad trajectory technique assisted by Iso-C 3D scan and 3D navigation system. Cyclic loading tests were performed with a maximum 250 N load at 3 Hz up to 30000 cycles while recording load and displacement. Stiffness quotients were calculated it comparison.

从尸体中获取6节腰椎椎体经DEXA和QCT检测骨密度值，证实为骨质疏松后在计算机导航下按随机分组的方法向12个椎弓根中置人不同方向的椎弓根螺钉，使用MTS-858生物力学仪脊柱力学测试平台进行±250N的循环负荷疲劳测试，记录负荷循环中的螺钉位移，计算系统的刚度系数并进行对比分析。

I wil leave quietly...wont bring for u any trouble, i dun wan mk u feel tired n troublesome, i don wan c u wondering wat 2 do whn i wana leave...for u i think i mean nth right now, u wont upset after i leave, wont miss me, nt nd remember me, nt nd put my deep inside ur heart, there's no point anymore...put down me, let me go...there wont hv love anymore after give up, wont leave anything anymore...love is gone..wont return..love wont be back...

我会静静地离开，不会给你造成任何麻烦，不想在让你觉得很累，很烦，不想在让你进退两难。。。。对你而言我也应该不是甚麼了吧，所以你也不会感到难过，也不会在留恋我，不需要在记得我，不需要在把我记在心里头，放下我，放开我的手吧。。。。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.
