激光辐照加电场激励对滇稻生长发育的影响

用激光辐照加电场激励处理滇稻种子,并对之进行育秧和田间种植试验.多年来试验表明,在出苗率、有效分、结实率和千粒重等诸多方面均优于单纯用激光处理的稻种和对照(CK).本文分析了激光和电场对生物分子共同作用的机制.     

关于一维相对论振子

本文用求解相对论振子运动方程的方法,不仅得出了R.Penfield和H.Zatzkis从能量守恒原理出发推得的振子位置、振子速度与时间的关系式,且还得到了一个较之更一般(即不必附加t值甚大条件)的关系式。     

高效液相色谱法测定蜜桶花颗粒及其原植物来江藤中的麦角甾苷

建立了用高效液相色谱法测定蜜桶花颗粒及其原植物来江藤中麦角甾苷含量的方法。实验采用C18柱,以甲醇-0.5％醋酸水(体积比为42∶58)为流动相,在334 nm检测波长处检测。结果表明:麦角甾苷的进样量为0.029~2.038 μg时,进样量与色谱峰面积有良好的线性关系(r=0.9998);回收率为90.2%~93.8%;方法的精密度好,相对标准偏差(RSD)为0.34％(n=5)。方法快速、简便、准确,所测结果稳定、重现性好,可作为蜜桶花颗粒质量控制的一个检测方法。     

Principle of equal effects of general relativity and invariance of classical mechanics equations

This paper gives the proof that the“inerial forces”in a noninertial system arenot fabricated forces,but potential forces which actually act on the objects in motionin the acceleration field,according to the equivalent principle between gravitation andinertial forces in the theory general relativity.Further,the invariance of kineticalequation is illuminated.     

Solutions of the modification heating conduction equations of a kind of laser thermal effect

This paper has solved the Chester modified heat conduction equation of the different relaxation time Υ value under different temperature conditions, different boundary conditions and the different initial conditions by different means of methods. These solutions can help to obtain temperature field of laser thermal effects.     

Derivation of the modification heating conduction equation of a kind of laser thermal effect by quantum mechanics

The Fourier equation of heat conduction predicts a paradox that the effect of a thermal impulse (e.g. the thermal effect in pulse laser) in an infinite medium; i.e., a thermal impulse is propagated in an infinite velocity. In order to solve the thermal transport paradox, C. W. Ulbrich and M. Chester have proposed the modification heat conduction equation respectively from different macroscopic viewpoint. This paper derived the modification heat conduction equation according to phonon model and quantum mechanics from microscopic viewpoint.
