In the process of laboratory study, oxycodone was prepared by oxidating thebaine at 6,14-position under oxydol, hydrodeoxidizing 7,8-position double bond and 14-position ether under palladium catalyst. Furthermore, N-methyl of oxycodone was isolated byα-chloro-ethyl chloroformate under anhydrous condition and protection of 14-position hydroxyl to obtain noroxycodone, which was further converted into methylnaltrexone by N-alkylation in presence of cyclopropyl bromomethane, then by isolating 3-position methyl of methylnaltrexone under boron tribromide, becoming hydrochloride to prepare target compound, natrexone hydrochloride.

They lose themselves in the titillation of language and form; they are infatuated with fragmentary appropriations of the classics; they are infatuated with the emptiness of decline and the passion of desire. As with the Western artists Jan Saudek and Joel-Peter Witkin, 'real-world objects should give up any idea of entering my pictures,' unless they undergo restructuring—by the artist's own taste and proclivities, by an amalgam of memory and fantasy, by a tone of pensive irony, or by seemingly absurd but in fact accurate imagination, thus restructuring the individual's relation to reality. It does not hurt to call these artists' work realism, but it is a kind of 'psychological realism' which 'extracts a deeper level of genuineness from fictive objects.

他们迷恋于语言与形式的快感，迷恋于对文化经典的片断性挪用，迷恋于衰朽的虚无或色欲的激情，与简·索德克、乔·彼得·威金（Joel-Peter Witkin）那样的西方艺术家相似，"现实中的事物永远别想进入画面"，除非是经过了他们的重构——以其个人的趣味与癖好，以混合着追忆与幻想、伤感与反讽的语调，以看似荒诞其实准确的想象力，重构了个人与现实之间的关系，你也不妨将他们的作品称之为现实主义，但那是一种"心理现实主义"——"从虚构的事物之中抽取出更深层的真实。"

And this plan is ascribed by some writers to Pfuhl, by others to some Frenchman, and by others to Barclay de Tolly; while other writers give the credit of this supposed scheme to the Emperor Alexander himself, supporting their view by documents, proclamations, and letters, in which such a course of action certainly is hinted at.

谈到拿破仑已经感到战线拉长的危险，谈到俄国人方面有意诱敌深入俄国腹地，显然其假设都是属于这一类的推测；只有历史学家才能非常牵强附会地把那样的推测强加在拿破仑和他的将帅身上，把那样的计划强加在俄国军事将领身上。

According to the H NMRstudy, it was found that the protons on the cyclopentadienyl ring of 〓 were not splitted, but when one proton on the cyclopentadienylring was substituted by methyl, that is in〓 complexes, thefour protons on the ring were splitted into four groups,the 〓 between the onesignal and the others is large, the total splitting is over 2ppm. The splittings werealso affected by the halides linked with the titanium, they increase according to theorder of CI, Br, I. By the study of the 〓 Sn NMR, it is found that the chemicalshifts of 〓 are present in low field. It is assume that the large space strain causesthe angles of the tin linked with ligands deviate from the normal tetrahedral anglesresults low field shift for 〓Sn. And by MS study,there were no molecular ions for 〓 complexes in the spectra. However, for 〓 when X=CI,Br,NCO and Ar is tolyl or phenyl group,there were molecular ions,but theirabundances were very small,and no that for the iodide was found.

钛上的卤素对茂环氢的裂分也有影响，依〓，Br，I顺序，卤素对茂环氢的裂分依次加大；通过对〓的研究发现，以上这些化合物〓的化学位移都出现在低场，认为大的空间张力造成的锡的键角偏离正常的锡的四面体键角是造成〓化学位移出现在低场的原因；对这些化合物质谱的研究发现，〓系列化合物得不到分子离子峰，而〓系列的化合物，当X=〓，NCO和苯环上不带取代基或只带甲基时，则出现分子离子峰，但丰度很低，而相应的碘化物和其它化合物则没出现分子离子峰。

Applied widely in the data encryption, pseudorandom sequences can be generated not only by hardware but also by trace function, and it is found that the sequences generated by trace function are much better than those generated by hardware, especially in the aspects of correlation properties.

摘要伪随机序列被广泛应用于数据加密，它既能利用硬件产生，也可以利用有限域上的迹函数来生成，并且由后者生成的序列的密码特性远远优于前者，特别是在相关函数方面更是如此。

Methods The antimicrobial peptides of housefly larvae were induced largely by infection and injury, which were isolated and purified by trituration, centrifugalization and column chromatography. Then the antimicrobial peptides with anti-Toxoplasma activity were sieved by methyl thiazolyl tetrazolium colorimetric method and haemacytometry. The DNA contents of T.gondii tachyzoites were detected by flow cytometry.

HPLC-MS data should be supplemented to the HPLC fingerprint information for a secondary peak matching.BP artificial neural network is then constructed by MATLAB 5.3 to recognize the fingerprints of Epimedium Brevicornum by the pattern recognition model based on the fingerprints of TCM. The model discriminates 5 categories of crude Epimedium Brevicornum from each other successfully.Inspired by the success of blended wine, attempts are made for the first time to simulate the trueborn crude Epimedium Brevicornum by blending the crude Epimedium Brevicornum of various sources.
