Magnetic properties of a series of Cd1-xMnxSe quantum dots with different sizes and Mn concentrations were measured by using superconducting quantum interference device magnetometer. The field dependent magnetization of the Cd1-xMnxSe quantum dots at 2 K was obtained and it was identified not to be dominated by CdSe quantum dots but Mn ions.

我们利用超导量子干涉仪量测不同尺度(D = 5 nm， 8 nm)及不同Mn浓度(x = 0.375%， 0.75%， 1.5%)的Cd1-xMnxSe奈米颗粒磁性；我们推测在温度2 K下，所量测的磁化强度是由Mn原子贡献而非来自奈米颗粒，拟合其磁化强度对磁场曲线图而得出样品中Mn原子个数，同时假设Mn离子的磁性行为高达室温仍满足Brillouin function和Curie顺磁定律，所以可从高温的数据扣除Mn的顺磁贡献。

The measurements of self-diffusion coefficient,spin-spin relaxation and interproton distance at 318 K suggest that N,N′-bis-α,ω- alkane propane diammonium dibromide (16-3-16) quasi-global micelles are formed in the dilute solution at a concentration of 0.26 mmol/L and the head groups are in a saw-toothed form staying at the surface of the micelle to overcome the strong electrostatic repulsion force.

Based on the ICMmethod,the discrete topological optimization problem about spot-weld's existence or not is transformed into the continuous optimization problem on[0,1].The optimization model is founded with maximizing the structural stiffness as objective and structural strength as constraints.The problem of multi-objectives and multi-constraints is transformed into the problem of single-objective and single-constraint with the K-S function.The displacement and stress are transformed into the explicit function of design variables with the Response Surface Methodology.The optimization model is solved with Sequential Quadratic Program.
