But the space is the matter, the matter is the string vibration, only has from this the time which vibrates f=1/T to draw out only then has the physics significance, therefore T is in the true significance time, from this deduction: What imaginary number Ict expresses is void, may write *ct,=I pure imaginary number, also is it with Number space Sigma (x1i*x2j)(i, j is subscript, i=j=1,2,3) differs 90 in the space, the shape for example: Psi ==a+Ib, constitutes a duplicate space by psi i* psi j,(definition mark * for ordinary multiplication) may use Four single numbers

而空间就是物质，物质就是弦的振动，只有从这个振动f=1/T引出的时间才有物理意义，所以T才是真正意义上的时间，由此推论：虚数Ict所表达的是一个虚空间，可以写成*ct，=I纯虚数，也即它与实空间Σ(x1i*x2j)(i，j为下标，i=j=1，2，3)在空间上相差90度，形如：ψ==a+Ib，由ψi*ψj构成一个复空间，可用四元数

Results The distinctive PCR products of the 6 isolated strains from Liaoning and Jilin areas through restriction with Hinf I ,Hha I ,Rsa I appeared two different kinds of RFLP restriction map. The strains HCAa9202,HCAp9203 and HCM9501 had the similar restriction maps with reference strain Gilliam,but they did not have restriction site of Hinf I ;Strains KDCt9402,KDCp9403 and KDCt9404 had the simular testriction map with reference strain Karp.

For any two vertices u and v of a graph G, a u-v geodesic is the shortest path between u and v. The set I consists of all vertices lying on a u-v geodesic. For SV, I is the union of all sets I for vertices u, v∈S. The geodetic number g is the minimum cardinality among the subsets S of V with I=V.

对于图G内的任意两点u和v，u-v测地线是指在u和v之间的最短路。I表示位于一条u-v测地线上所有点的集合，对于SV，I表示所有I的并，这里u，v∈S，G的测地数g是使I=V的最小点集S的基数。

objective effects of plant tannins,chebulinic acid and tellimagrandin i on chemically induced hemoglobin synthesis in k562 cells were investigated.methods the hemoglobin synthesis situation was assayed with benzidine staining.erythroid antigens glycophorin a expression on the surface of k562 cells was labeled by direct immunofluorescence using fluorescein isothiocyanate-conjugated anti-gpa antibodies.then flow cytometric analysis was performed to detect gpa expression levels on surface of the cells.results both chebulinic acid and tellimagrandin i could inhibit the hemoglobin synthesis of butyric acid and hemin-treated k562 cells in a concentration-dependant manner.however,the ba-induced k562 cells were more sensitive to two tannins than heroin-induced cells.conclusion chebulinic acid and tellimagrandin i have inhibitory effect on the erythroid differentiation.

Assisted by DNA2.0 and Gene2Oliga software, we optimized the codon usage and secondary structure of RNA and induced enzyme sites Cla I (237 site) and Pst I (475 site) into the gene. In the first step, fragments F1 (237 bp), F2 (238 bp) and F3 (422 bp) were separately synthesized by assembly PCR. In the second step, fragments F1, F2 and F3 were separately digested by Cla I and Pst I, and then ligated into a full length lipA gene.

MCM-41, HMS, and MSU mesoporous silica molecular sieves were prepared via S〓I���, S〓X〓I���, S〓I���, and N〓I��� assembly pathway, in which cetylpyridium bromide, tetredecylamine, and polyoxyethylene (10) stearyl ether was used as the template, respectively. The mesostructures were characterized and confirmed by XRD, N〓 adsorption/desorption, TG, and high resolution TEM. The difference and relationship between these mesophases were also investigated.

At the same time, the intensity ratio of the ICT fluorescence to the LE fluorescence, I���/I���, shows a "bell"-shaped variation with increasing CTAB concentration The intensity ratio was found to level off after the CMC of CTAB Together with the data from UV-Vis absorption spectroscopy, electric conductance measurements and the control experiments with tetramethylammonium bromide, it was concluded that the"bell"-shaped variation in the intensity ratio before CMC is due to the formation of premicelle aggregates consisting of ICT fluorophore and CTAB.

此时，ICT荧光强度与LE荧光强度之比，I〓/I〓随CTAB浓度增大而呈&钟形&变化。当CTAB浓度高于CMC时，I〓/I〓为一常数。根据紫外-可见吸收光谱，电导以及四甲基溴化铵对照实验的结果可知，当CTAB浓度低于其CMC时，I〓/I〓的&钟形&变化是由于长链对二烷基氨基苯甲酸与CTAB组成的胶束前簇集体形成所致。
