企业商号吸收社会储蓄,在近代中国是一个普遍现象。这种现象在二十世纪二十年代后发生了演变,成为企业商号发展壮大的重要资金来源。由于这种现象对银行业的利益造成冲击,也与南京政府规范金融秩序的要求不符,1930年曾由南京政府财政部颁发过禁令,对这种现象进行禁止。但由于种种因素的制约,企业商号吸收社会储蓄的现象仍然得以存在,并在近代中国经济发展进程中发挥着重要的作用。

相对论性量子力学波动方程,如狄拉克、外尔和麦克斯韦方程,是描述微观粒子运动的基石.最近的实验和理论研究表明,冷原子系统中几乎所有参数都可精确调控,因此冷原子系统被认为是实现量子模拟的理想平台,可以用来研究高能和凝聚态物理中的一些基本问题.本文介绍了设计原子光晶格哈密顿量的思路和方法,主要涉及激光辅助跳跃的理论.基于这些方法,物理学界提出了利用光晶格体系模拟相对论性量子力学波动方程,包括狄拉克、外尔和麦克斯韦方程等,并且预言了一些在基本粒子物理中很难观察到,但在冷原子体系可能观察到的物理现象.本文综述了国际上此领域的研究进展.

Alternating multilayer films of hydrogen diluted hydrogenated protocrystalline silicon (pc-Si:H) were prepared using a plasma-enhanced chemical vapor deposition *** microstructure of the deposited films and photoresponse characteristics of their Schottky diode structures were investigated by Raman scattering spectroscopy,Fourier transform infrared spectroscopy and photocurrent *** and optical absorption analyses suggest that the prepared films were pc-Si:H multilayer films with a two-phase structure of silicon nanocrystals (NCs) and its amorphous counterpart and the band gap of the films showed a decreasing trend with increasing crystalline *** measurement revealed that silicon NCs facilitate the spatial separation of photo-generated carriers,effectively reduce the non-radiative recombination rate,and induce a photoresponse peak value shift towards the short-wavelength side with increasing ***,the carrier traps near the surface defects of silicon NCs and their spatial carrier confinement result in a significant reduction of the diode photoresponse in the longwavelength *** enhancement of the photoresponse from 350 to 1000 nm was observed when applying an increased bias voltage in the diode,showing a favorable carrier transport and an effective collection of photo-generated carriers was *** the spatial separation of the restricted electron-hole pairs in silicon NCs and the de-trapping of the carriers at their interface defects are responsible for the red-shift in photoresponse spectra and enhancement of external quantum *** results provide fundamental data for the carrier transport control of high-efficiency pc-Si:H solar cells.

This study develops a coupled multiphysics finite element method for the dynamic analysis of a bare flexible electrodynamic tether. Contrary to the existing methods, the new method discretizes and solves the orbital motion limited equation and the dynamic equation of an elastic flexible tether ***, the new method is verified via comparison with the existing methods in a straight tether ***, the number of tether elements, tether bending deformation, and two design parameters at the cathodic end affecting the electrical current are investigated. It is determined that the tether bending deformation and the two parameters i.e., the impedance ZT and ΦPWhave a significant impact on the electron collection efficiency of an electrodynamic tether system. The results indicate that the proposed method should be applied in the refined mission analysis.

Molecular imprinted nanoparticles(MINPs) can memorize the shape and functional group positions complementary to template, which account for the large drug loading capacity and slow drug release behavior as drug carriers. We synthesized MINPs via precipitation polymerization with vinblastine(VBL) as a model drug, and investigated the drug loading,releasing property in vitro and bio-distribution in vivo. The obtained MINPs, from 300 to 450 nm,had smooth surface and favorable dispersibility. The entrapment efficacy and drug loading capacity of VBL loaded MINPs(MINPs-VBL) were 83.25% and 8.72% respectively. In PBS(pH 7.4),MINPs-VBL showed sustained release behavior. The cumulative release percentage reached about 70% during 216 h and no burst release was observed. The releasing behavior of MINPsVBL in vitro conformed to the first-order kinetics model. MINPs-VBL and commercially available vinblastine sulfate injection(VBL injection) were injected via tail vein of SD rats respectively to investigate the bio-distribution. MINPs-VBL group showed higher concentration of VBL in tissues and serum than VBL injection group after 60 min, and the drug level in liver was the highest. MINPs-VBL exhibited liver targeting trend to some extent, which was based on the evaluation of drug targeting index(DTI) and drug selecting index(DSI).

利用一种新的电铸技术——游离粒子辅助摩擦电铸技术进行Ni-Mn合金的电铸试验。研究了工艺参数对Ni-Mn合金电铸层显微硬度和拉伸性能的影响规律。试验结果表明,游离粒子的辅助摩擦作用和电铸层中的锰元素共同影响着电铸层的力学性能。随着阴极旋转速率的提高,电铸层中锰含量不断增加,且游离粒子对电铸层的摩擦、挤压作用随之加强,电铸层的显微硬度和抗拉强度都不断提高;随着电流密度的提高,电铸层中锰含量也不断增加,电铸层的力学性能发生波动。在一定锰含量范围内,随着电铸层中锰含量的增加,电铸层的力学性能也随之提高。中温退火处理后,当电铸层中锰含量较低时,电铸层将会出现再结晶现象,晶粒尺寸增大,其力学性能下降,当锰含量高于0.2%(质量分数),其力学性能要高于热处理前。
