The sticking phenomenon during hot rolling of SUS 430 ferritic stainless steel was investigated by means of a two-disc type high-temperature wear tester. The test results indicate that sticking particles on the surfaces of high chromium steel （HiCr） and high-speed steel （HSS） rolls undergo nucleation, growth, and saturation stages. Grooves on the roll surface generated by grinding provide nucleation sites for sticking particles. The number of sticking particles on the HiCr roll surface is greater than that on the HSS roll surface. The average surface roughnesses （Ra） of HiCr and HSS rolls change from 0.502 and 0.493 μm at the initial stage to 0.837 and 0.530 μm at the saturation stage, respectively. The test further proves that the sticking behavior is strongly dependent on roll materials, and the HSS roll is more benefi- cial to prevent particles sticking compared with the HiCr roll under the same hot-rolling conditions.

The Schrödinger equation of a three-level atom in an electromagnetic wave of circular polarization is *** solution to this equation shows that under the action of the circular polarized electromagnetic wave,the levels of aΣ-type atom split into nine sublevels,while those of a V-type orΛ-type atom split into six *** means of some special tuning ways and approximation conditions,the energies of the spilt levels are expressed in simpler forms.

The emission spectra of a two-level atom moving in an electromafneric fiekd are studied We find that there that there is a shift in the peak position and that each peak splits into double peaks The shit is duble peaks The shift is duc to the detuning indced by the atomic mition and the splitting is casused by the atomic energy change due of photons.

In urban environment with serious blocking of direct paths, the non-line-of-sight （NLOS） propagation influences the location estimation accuracy. In this article, a novel algorithm is developed, which can mitigate the NLOS errors in location estimation significantly. Utilizing multiantenna array, the information of scatterers that cause the NLOS propagation is obtained. Then, we combine the information with TOA/TDOA based location algorithm to estimate the location of mobile station （MS）. The simulation results show that our method can mitigate NLOS errors and enhance the location accuracy greatly.

Using a nonperturbative quantum electrodynamics theory of high-order harmonic generation （HHG）, a scaling law of HHG is established. The scaling law states that when the atomic binding energy Eb, the wavelength ）, and the intensity I of the laser field change simultaneously to kEb, λ/k, and k3I, respectively. The characteristics of the HHG spectrum remain unchanged, while the harmonic yield is enhanced k3 times. That HHG obeys the same scaling law with above-threshold ionization is a solid proof of the fact that the two physical processes have similar physical mechanisms. The variation of integrated harmonic yields is also discussed.

目的研究探讨真核释放因子eRF3a的RNA干扰如何影响心脏钠通道无义突变的表达和功能。方法构建心脏钠通道无义突变和干扰eRF3aRNA的真核表达载体，独立或共同转染HEK293细胞，全细胞膜片钳记录钠通道的表达电流和动力学，同时应用蛋白印迹和免疫荧光证明钠通道的表达和定位。结果独立转染W822X无义突变的HEK293细胞没有检测到全长钠通道蛋白，表达的钠电流水平很低，仅相当野生型钠电流3％。共同转染HEK293细胞可以检测到全长钠通道蛋白，表达的钠电流水平明显增加，相当于野生型钠电流30％。免疫荧光也显示，独立转染W822X无义突变的HEK293细胞没有出现荧光细胞，而共同转染的HEK293细胞出现较多的荧光细胞。结论真核释放因子eRF3a的RNA干扰促进心脏钠通道无义突变的翻译，部分恢复钠通道全长表达和功能。
