Based on the tensor expression for the Breit-Pauli Hamiltonian,and with the aid of irreducible tensor theory,the theory of relativistic corrections to the non-relativistic energies of many-electron atoms has been generalized to the case in which Racah wave functions are the linear combinations of multi-Slater wave functions,analytic formulism for calculating the relativistic corrections,which include mass correction,one-and two-body Darwin correction and spin-spin contact interaction,has been derived,all the angular interactions and spin sums involved in the problem have been worked out explicitly by using irreducible theory.

以Breit-Pauli哈密顿的球张量形式为基础，借助不可约张量理论，将多电子原子能量的相对论修正理论拓展到了原子的拉卡波函数为多个Slater基函数的线性组合的情形，导出了此情形下多电子原子能量相对论修正(包括相对论质量修正项、单体和双体达尔文修正项、自旋-自旋接触相互作用项)的解析表达式，完成了所有角向积分和自旋求和计算。

The rate of pleural effusion to diagnose is 88.9% under thoracoscopy:tuberculous pleurisy displays mainly pleura hairy nubble and diffuse white millet nubs and pleural thickeningthe trabe-form conglutination can been found; and metastatic tumor of pleura shows gray tuberculum impar and inequality of size nodosities with diffused pleural congestive and edema in the CPA and disphragmatic muscle.

结核性胸膜炎主要表现为胸膜多发结节，部分病灶出现弥漫性白色粟粒样结节和胸膜增厚，可见条索状粘连；而转移性胸膜肿瘤主要表现在肋膈角、横膈处的灰白色单结节和大小不等的多结节；非特性慢性炎症性胸膜炎主要为胸膜充血水肿，胸膜增厚纤维增生或粘连，少见有单个或多个结节增生。

After each serial measurement, it is not necessary to change the relative position of the two pitch circle devices, so the process of mutual check is simplified and the measuring time is shortened.

针对此缺点，本文提出采用排列常角法实现正多面棱体和多齿分度台角分度误差的互检，不需要在每个测回完成后改变两个圆分度器件的相对位置，从而简化了互检过程，缩短了测量时间。

The rocking curves of different area have been measured by high resolution X-ray diffractometry. The reflections were indexed, furthermore the polytype structures were identified. The results are consistent with those of Raman spectroscopy analysis. It is demonstrated that Raman spectroscopy is a simple and powerful method for the determination of SiC polytypes.

Self-fluxing Fe-Cr-Ni-B-Si alloy prowders are laser clad on medium carbon steel substrate of dimensions 80×35×10mm〓. The investigation results of this clad layer are: micro-defects, micro-cavity and occluded forin substance, are the micro-cracks and crack resourses in clad layer; crack of coating propagates along the boundary of two kinds of eutectic sutructure; The included angle θ between the cracking direction and laser scanning direction in multitrack overlapping clad is smaller than that in one-track clad because of crack propagating along crystalline growth direction and crystalline direction in overlapping zone being different from it in one-track clad.

在调质态的45〓钢表面，采用预置粉末法进行FeCrNiBSi合金的多道搭接激光熔覆，对其熔覆层进行分析表明：多道搭接激光熔覆层裂纹扩展方向与激光扫描方向间的夹角θ与单道熔覆时相比明显变小，前者θ0°，后者θ角基本都为90°，这主要是因为多道搭接时，搭接区结晶方向发生了变化以及裂纹沿结晶方向扩展所致；激光熔覆层裂纹大多是以覆层与基材交界面的孔洞、熔覆层内不同方向共晶团间的显微缩孔、夹杂物的边界等三种显微缺陷作为裂纹源，并沿低熔点物相形成元素偏析造成弱化膜的共晶团界面扩展延伸。
