The strategy involves a staged combustion, where a hydrocarbon fuel added in the second, fuel-rich stage provides hydrocarbon radicals which can react with and finally reduce the NOx formed in the first, fuel-lean stage, such that NOx formed in the first stage reacts with small hydrocarbon radicals present in the second stage combustion, finally leading to N〓, and to HCN which in turn is converted to NO or N〓. Understanding of the chemistry in this second reburning stage is clearly a key to understanding and optimizing reburn technology.

目前消除NOx的主要方法是向燃烧的废气中加入某些化学物质使其重新燃烧(Selective Noncatalytic Reduction of NO processes，SNCR)，RAPRENOx过程是SNCR的主要方式之一，其实施是向燃烧产生的废气中加入异氰酸，异氰酸在高温下经一系列包括NCO的自由基反应，可以从燃烧的废气中迅速除去NOx化合物。

Results: The cultured chondrocytes were polygonal cells. There were many rough endoplasmic reticula and mitochondria in cytoplasm, and a lot of secretory vesicles under cell membrane and in the cytoplasm. When cultured for 10 days, some small and white nodules were formed on the bottom of the culture dished, and volcanic-mouth-like structures were formed when cultured for 20 days. Both these nodules and structures contained GAG-positive substances were demonstrated by safranine-O staining.

EAA formed a rodlike extension structure in PP matrix, and much more continuous structure are formed, which resulted in a rapid decreasing of the volume resistivity with the increasing of EAA resin content.

EAA相在PP基体中呈棒状伸长结构，且随着EAA树脂含量的增大，在PP基体中形成更多更为连续的棒状伸长结构，使体积电阻率迅速下降。

Under low temperature condition, fertility restoring, anther developing normally, the tetrads formed after archesporical cell, sporogenous cells and microspore mother cell. Subsequently, microspores were free from the tetrad of fertile anther and formed mature pollen grains, tapetumof the fertile anthers began to disintegrate and disappear at last.

在低温处理条件下，育性恢复，花药发育正常，经过孢原细胞期、造孢细胞期、花粉母细胞期后，可以顺利形成四分体，可育花药的四分体可以释放出小孢子并发育为成熟的花粉粒，同时绒毡层细胞开始解体，最后消失。

A columnlike structure, especially one formed by the union of a stamen and the style in an orchid flower, or one formed by the united staminal filaments in flowers such as those of the hibiscus or mallow.

蕊柱一种柱形结构，尤指由兰花中雄蕊和雌蕊组成的结构，或指由木楼或欧锦葵属雄蕊联合构成的柱状结构

Botany A columnlike structure, especially one formed by the union of a stamen and the style in an orchid flower, or one formed by the united staminal filaments in flowers such as those of the hibiscus or mallow.

The second group are the mixtures of Jurassic coal-formed oils and Cretaceous-derived oils. The carbon isotope, n-alkanes and isoprenoids compositions of these oils are similar to core extracts from Jurassic coal measures. However, sterane and terpane compositions of these oils show affinity to Cretaceous source rocks. It is deduced that coal-formed oils dissolved the biomarker-rich Cretaceous bitumen of relatively low thermal maturity, and overprinting occurs during oil migration.

第二类原油具有侏罗系煤系烃源岩与白垩系湖相泥质烃源岩混源的特点，这类原油的碳同位素组成、正构烷烃分布特征和姥植比等均表现出煤成油的特征，但甾、萜烷烃类化合物组成与白垩系烃源岩接近，推测是由于侏罗系煤成油在向上运移成藏过程中，受到成熟度相对较低、生物标志物相对丰富的白垩系烃源岩的浸析作用所致。

All the ligands and complexes have been characterized with ~1H-NMR, MS and EA.X-Ray single crystal diffraction reveals that zirconium complex containing the tert-butyl substituted N_2O_2 ligand is an oxo- and hydroxyl-bridged dinuclear structure, which is possibly formed by partial hydrolysis of chlorides at one of the zirconium centers. A tetranuclear zirconium complex has been obtained and chacaterized, which is formed by complete hydrolysis of the chlorides at the zirconium centers.

通过研究配合物的单晶结构，我们发现叔丁基取代的不对称N_2O_2配体与ZrCl_4反应生成的锆配合物为氧桥和羟基桥连接的双核锆配合物，中间过程涉及单核锆配合物中氯原子部分水解，并得到氯原子部分水解的双核锆配合物和全部水(来源：8e6eAB67C论文网www.abclunwen.com)解的四核锆配合物的晶体结构，在晶体培养过程中发现双核锆配合物能够以手性自发拆分结晶析出。

Several novel structures have been determined: Unique ninenuclear complexesincorporating 3d, 4f metals with a sodium ion center, the sodium ion may be serve as atemplate in the formation of these novel complexes; Novel tetranuclear 〓complexes with channels formed by intermolecular weak interactions; First 〓type tetranuclear complex; Peculiar "dimer of dimers" complexes derived frombinuclear complex; Unusual one-dimensional wave chain formed by weakcoordination bonds and hydrogen bonds and two dimensional coordination polymerconstructed through coordination bonds and hydrogen bonds.

1获得了多个文献首报和罕见的特殊结构的配合物：两个同时含有碱金属-过渡-稀土金属的独特的九核配合物；两个具有孔道的稀土-过渡金属异四核配合物；草酰胺类〓四核配合物；两个由双核配合物通过叠氮和单个氯原子连成的四核配合物，尤其是以单个氯桥相连的化合物非常少见；一个由弱配键和氢键连成的具有一维波浪形结构的配合物；一个通过配位键和氢键连成的二维配位聚合物。

Obvious cartilage and island-distributed immature bone formation in implants of the experiment side were observed at 2 weeks after operation, and massive mature bone observed at 4 weeks. Newly formed bone had fused and formed mature lamellar bone and trabecularism. No bone formation was observed in the control side of the mice.

实验侧术后2周出现大量软骨组织和呈岛状散在分布的骨组织，术后4周可见大量成骨组织，新生骨相互融合生长并形成较为成熟的板层骨和骨小梁结构；对照侧未见骨组织形成。
