The characters of regeneration niche for seed germination,seedling growth,soil seed bank and vegetative reproductionof Papilionaceae and Car agana spp.andits relationship withrestoration of desert vegetation were summarized,for the purpose of providing theoretical basis for regeneration niche in the study onreproductive biology and restoration ecology of C.spp..

对蝶形花科，锦鸡儿属落叶灌木柠条(Caragana spp。)的种子萌发、幼苗生长、土壤种子库和营养繁殖等更新生态位特征及其与荒漠植被恢复的关系进行了综述，旨在为柠条的繁殖生物学和恢复生态学研究提供更新生态位方面的理论依据。

Ten variously substituted benzoyl peroxides were synthesized for Raman spectrometric identification both in solution (CCl 2FCClF 2) and solid state. Different to infrared spectra, Raman spectra have been proved to be a useful characterization of the highly symmetric peroxy bond in diacyl peroxides. The ν OO value ranged from 850 to 899 cm -1 varies regularly with the substituent on the phenyl ring.

合成了全氟和其它对位、间位取代的共10种过氧化苯甲酰，测定了它们的固体和溶液(溶剂为F113， CCl2FCClF2)的激光拉曼光谱，首次发现这类化合物中高度对称的过氧键有较强的特征谱带，即νOO在850至899 cm-1之间，并随取代基不同而呈现规律变化。

The structure characters of this kind of molecules were discussed. The results show that the phenyl group located in the 4- or 5- position of pyrryl ring are not coplanar with the pyrryl ring.

对这类吡咯环上4或5-位有芳环取代基时化合物的晶体结构特征进行了扼要讨论，晶体衍射实验结果表明，4， 5-位上的芳环与吡咯环本身处于非共平面结构。

Eighty six cases were confirmed by operation.The overall diagnostic coincidence rate was 98.98%.Conclusions:TV-CDE is worthy of diagnosing salpingian pregnancy.

TV-CDE是目前诊断早期异位妊娠有价值的检测手段，其血流频谱特征和&输卵管环&具有特殊诊断及鉴别诊断意义，尤其是对异位妊娠早期诊断具有特异性。

Methods:TV-CDE were performed in the diagnosis of salpingian ectopic pregnancy.Imaging and blood flow spectrum were analyzed,Vs,Vd,RI and PI were measured.Results:TV-CDE could show the signals of blood flow very well.

应用TV-CDE技术对98例临床疑诊异位妊娠患者的附件区包块行阴道二维超声图像、血流显像及频谱特征进行对照分析，对Vs、Vd、RI、PI值进行测量，分析了TV-CDE对异位妊娠定性的可行性。

Presents the microstructure evolution in aluminum a nd copper after deformation by cold rolling in the strain range of 10 to 50%red uction using TEM and points out three types of dislocation structures are typica l and two of them are common for both materials and these two common types are f ound in non-cube grains and can be distinguished by crystallographic orientatio n of dislocation boundaries in the grains and the third type of structure is obs erved in cube grains, and concludes that grain orientation is important in deter mining the structure type but some other metallurgical parameters also have a ro le to play.

采用TEM对冷轧多晶铜与多晶铝的形变显微组织演变进行了对比研究。结果发现：多晶铜及多晶铝形变显微组织中均含有三类典型的位错结构类型，其中的两种结构特征在两种材料中是相似的，这两种类型结构存在于非立方取向晶粒，可通过晶粒中位错边界的晶体学取向加以区别，另一类型结构存在于立方取向晶粒；晶粒的晶体学取向决定了其形变显微组织类型，但其它冶金学因素对显微组织也有影响。

Bases on the outline of priority, the first part analyze the priority"s concept and characteristics, and promulgates the priority"s nature and potency thoroughly. The priority is thought to be a legal guarantee real right, and has the real right and the guarantee. Its potency mainly included first receives recompenses potency, the former generation position potency, overtakes potency and the prioritys cis-position four aspects.

第一部分从优先权的概述切入，分析了优先权的概念及特征，并深入揭示了优先权的性质和效力，认为优先权是一项法定的担保物权，具有物权性和担保性，其效力主要包括优先受偿效力、物上代位效力、追及效力及优先权的顺位四个方面。

Degree of aggregation of soil increases and constitutive property gradually enhances from upper slope to lower slope; of various types of utilizing on the same slope, the distribution of soil nutrients appears different variance characters, and the content of organic matter, total nitrogen, and alkali-hydrolysable nitrogen of reforested land is highest, which distinguishing from other types; the content of total phosphorus, total potassium, rapidly available phosphorus and rapidly available potassium of farm land is highest, which is not distinguished from two other types of utilizing.

从上坡位至下坡位土壤团聚度随之增大，结构性逐渐增强；同一坡面不同的利用方式，土壤养分分布呈现出不同的分异特征。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
