The asymmetric ring-opening of epoxides with dithiophosphorus acids catalyzed by a （salen）Ti（Ⅳ） complex formed in situ from the reaction of Ti（OPr-i）4 and the chiral Schiff base derived from （1R,2R）-（＋）-diaminocyclohexane was realized. The resulting products were obtained with low to good enantioselectivity （up to 73% ee）.

OBJECTIVE By analysis and evaluation of the perfusion images and perfusion parameters of the rabbits with VX2 lung tumor, the association between the perfusion parameters and tumor angiogenesis of patients with squamous cell carcinoma of the lung has been studied in order to establish a non-invasive and effective way to detect tumor blood supply, which is be able to exhibit hemodynamic data in tumors during cancer treatments. METHODS Fifteen Netherlands rabbits inoculated with VX2 lung tumor （rabbit group） and 25 patients with squamous cell carcinoma of the lung （patient group） received a multi-slice spiral CT perfusion imaging test using the Netherlands PHILIPS Brilliance 16-slice spiral CT and a U.S. MEDRAD binocular highpressure syringe. Image postprocessing was done using the special perfusion software and EBW 4.0 Workstation. Perfusion volume （PV）, peak enhanced increment （PEI）, transit time peak （TTP）, and blood volume （BV） were measured and analyzed. RESULTS In the rabbit group, the values of the PV, PEI, TTP, and BV of the tumor margin were （53.89 ± 13.38） mL/（***）, （45.71 ± 15.52） Hu, （39.29 ± 10.10） sec, and （31.45 ± 18.19） mL/100 g, respectively; these values of the tumor center were （36.57 ± 14.17） mL/（***）, （28.64 ± 11.74） Hu, （39.00 ＋ 9.78） sec, and （19.76 ± 13.95） mL/100 g, respectively; the values of the muscles were （12.45± 4.38） mL/（***）, （10.98 ± 5.03） Hu, （38.86 ± 10.04） sec, and （5.38 ±2.87） mL/100 g, respectively. The values of the relative perfusion volume （RPV）, relative peak enhanced increment （RPEI）, and relative blood volume （RBV） of the tumor margin were 4.38 ± 1.45, 3.96± 1.45, 9.99 ± 11.7, respectively; these values of the tumor center were 2.14 ± 1.08, 1.83±1.45, 4.17 ±3.39, respectively. The values of the PV, PEL BV of the tumor margin vs. the values of the muscles developed t-values, which were 15.028, 10.79, and 5.88, respectively （P ≤ 0.01）, with statistical significance; the values of the PV, PEI, BV of the tumor center v

he present paper covers a model involving Donnan memhrane equilibrium andadsorption eluilibrium to describe the retention process for diprotic organic acids inion-exclusion chromatography. On this basis the microcomputer simulation of elu-tion behaviour for dicarboxylic acids was investigated. Influences of eluent acidityand sample concentration on the retention value were studied. The theoreticallypredicted results are in reasonable agreement with the experimental data.

Tiller is one of the most important agronomic traits which influences quantity and quality of effective panicles and finally influences yield in rice. It is important to understand ＂static＂ and ＂dynamic＂ information of the QTLs for tillers in rice. This work was the first time to simultaneously map unconditional and conditional QTLs for tiller numbers at various stages by using single segment substitution lines in rice. Fourteen QTLs for tiller number, distributing on the corresponding substitution segments of chromosomes 1, 2, 3, 4, 6, 7 and 8 were detected. Both the number and the effect of the QTLs for tiller number were various at different stages, from 6 to 9 in the number and from 1.49 to 3.49 in the effect, respectively. Tiller number QTLs expressed in a time order, mainly detected at three stages of 0-7 d, 14-21 d and 35-42 d after transplanting with 6 positive, 9 random and 6 negative expressing QTLs, respectively. Each of the QTLs expressed one time at least during the whole duration of rice. The tiller number at a specific stage was determined by sum of QTL effects estimated by the unconditional method, while the increasing or decreasing number in a given time interval was controlled by the total of QTL effects estimated by the conditional method. These results demonstrated that it is highly effective and accurate for mapping of the QTLs by using single segment substitution lines and the conditional analysis methodology.

The improved Boussinesq equations for varying depth derived by Beji andNadaoka significantly improved the linear dispersive properties of wave models in intermediate waterdepths. In this study, a finite element method was developed to solve the improved Boussinesqequations. A spongy layer was applied at the open boundary of the computational domain to absorb thewave energy. The fourth-order predictor-corrector method was employed in the time *** test cases were illustrated. The numerical results of this model were compared withlaboratory data and those from other numerical models. It turns out that the present numerical modelis capable of giving satisactory prediction for wave propagation.

提出了一种具有宽绝对禁带的一维磁性光子晶体结构,该结构由相同的折射率和物理厚度以及不同的波阻抗的两种磁性材料交替组合而成.通过传输矩阵法分析可得,相比于非磁性光子晶体,该光子晶体的禁带对入射角和偏振都不敏感,从而具有更宽的绝对禁带.合适地调节两种磁性材料的参数,增加两者波阻抗的差值,该光子晶体的绝对禁带宽度也相应地增加;调节两种磁性材料的物理厚度,其绝对禁带中心也会随之调整;最后,将两个满足上述条件的一维磁性光子晶体组成异质结构,其第一禁带宽度与禁带中心之间的比值可达到1.41以上.
