By systematically analyzing the single particle level and the occupation probability near the Fermi surface,and the rule of nuclear particle number deviations with proton numbers for N =8,20,28,50,82,126 neutron chains within the relativistic mean-field model with BCS theory,we have discussed the stability of the shell structure for the traditional neutron magic in the whole range of nuclear spectrum from neutron line to proton line,and predicted that traditional neutron magic number effect shall possibly disappear only in light neutron-rich nuclei.

Liquid-phase epoxidation of allyl chloride with hydrogen peroxide was carried out over Ti-MWW, a novel titanosilicate with the MWW structure, to synthesize epichiorohydrin selectively and effectively. Ti-MWW proved to be superior to the conventional TS-1 catalyst in both catalytic activity and product selectivity. Ti-MWW prefers aprotic solvents of acetone and acetonitrile, both of which can restrain the solvolysis of epichiorohydrin, whereas TS-1 favors a protic solvent of methanol.

研究了具有MWW结构的新一代钛硅分子筛Ti-MWW催化剂对烯丙基氯液相环氧化高效合成环氧氯丙烷的催化性能结果表明，Ti-MWW的催化活性以及产物选择性均优于传统的钛硅分子筛TS-1，对于Ti-MWW，合适的溶剂为非质子性溶剂丙酮和乙腈，在该溶剂中环氧化物不易发生溶剂化开环反应；而对于TS-1，合适的溶剂是质子性溶剂甲醇，但甲醇可导致醇醚副产物的生成。

The mechanism of the reaction was studiedin detail,in which excited state avaliable to carryout the excited state intramolecular proton transferreaction was recognized.The INDO/S-CI semiempiricalMO method was used to calculate transition energiesand oscillator strength,and assign spectra theore-tically,the calculated spectra values were basicallyconsistent with the experimental values.Themolecular orbital properties for the adjacent HOMO-LUMO of various kinds of conformersand anion species,thetransition properties and symmetry for thetransition from ground state to lower excited stateswere analysed,especially,no much study on theanion species all of the world.

位能曲线的求法满足反应坐标是反应过程中能量最小途径的定义，较详细地研究了各类反应的质子转移历程，认定在哪个激发态有利于发生激发态分子内质子转移反应，用INDO/S-CI半经验MO方法进行跃迁能和振子强度计算及光谱的理论指认，计算的光谱值和实验值基本吻合，并分析了各种异构体和阴离子的HOMO-LUMO附近的轨道性质，各跃迁态的跃迁性质和对称性，尤其是对阴离子的研究国内外尚不多见。

The crystalline grains in Ni2 spheres are radially arranged and intervein and these grains connect with each other to form a three-dimensional network-type structure. This structure is supposed to benefit the mechanical stability for the spherical particles during the charge/discharge processes and improve cycle life of the electrode.

这种结构在电池的充放电过程中具有良好的力学稳定性，微球内存在的孔隙或缝隙可以用作质子传递的通道而有利於缩短质子在固相中扩散的距离，从而降低电极极化和提高电极的电化学性能及使用寿命。

For the case of pH-induced micellization, as pH of the solutions decreases to below 4.6, micellar structure having insoluble complexes of PAA/PNiPAAm as the core and solvated HEC chains as the shell can be obtained due to hydrogen-bonding complexation between the proton-acceptors in PNiPAAm and the proton-donors in PAA.

首先发现pH诱导胶束形成的临界pH值在4.6附近，证实了胶束化机理是由于低pH下PAA接枝链上的质子给体与PNiPAAm支链上的质子受体间的氢键络合形成胶束的&核&，HEC不参与络合形成胶束的&壳&。

In the proton, the process that the partons are created and destroyed happen all the time so that the Fock state of proton keep translate from one to another from time to time.

由QCD量子场论的特性可知质子内的部分子数并不是固定的，而是不断的产生和湮灭，因而质子所处的Fock态不断的从一个转变到另一个。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
