Results The incidence of wedge-shaped defects reached 97.3 %,and the frequency of involved teeth was:first premolar,second premolar,first molar,cuspid.

结果 该组老年人楔状缺损的发病率为97 。3 %，且随年龄递增；楔状缺损的好发部位和缺损程度第一双尖牙列首位，其次为第二双尖牙，第一磨牙；其中第一磨牙比以往人们认为的尖牙更好发楔状缺损。

The first three largest number of missing teeth is as follows: maxillary first molar, maxillary second molar and mandibular first molar. The first three largest number of resident teeth is as follows: mandibular cuspid, mandibular bicuspid and maxillary cuspid. The cases without occusal relationship account for 19.51%; and the cases which need occlusal reconstruction or occlusal elevation account for 19.51% of all the cases, while food impaction exists in 21.84% cases.

结果：本组老年人平均缺失牙齿9.10颗，缺失最多的前3位牙齿是上颌第一磨牙、上颌第二磨牙和下颌第一磨牙；余留最多的前3位牙齿是下颌尖牙、下颌第一双尖牙和上颌尖牙。19.51%的病例颌骨间无咬合接触关系，19.51%的病例修复时需咬合重建或咬合抬高；21.84%的病例修复前存在食物嵌塞。

With the aids of the angular momentum coupling theory, the diagonal sum rule and the irreducible tensor theory, a formulism for calculating the matrix elements of Boron-like atoms' non-relativistic Hamilton between the Racah wave functions have been derived. Based on this approach, the non-relativistic energies of Boron-like atoms in the ground and the first excited states have been obtained.

本论文借助角动量耦合理论、对角和法则和不可约张量理论，导出了类硼离子基态和第一激发态非相对论性哈密顿在拉卡基函数之间的矩阵元的表达式，给出了计算类硼离子基态和第一激发态非相对论性能量的方法，并应用此法计算了类硼离子基态和第一激发态非相对论性能量。

If the disk is infected with the virus, the memory is read the first part of the virus program, it has been modified after the control of the size of memory space available in high-end memory think of a region, and moved to the first part of the area, and then read on the disk "bad cluster" in the second part of the first part and to put together, so that all proceedings on the presence of the virus in memory of the high-end, and then modify the interrupt vector INT13H or other interrupt vector to the high-end virus program, then you can read the original boot memory and the control over to it to complete the system startup.

如果是染上病毒的盘，读到内存的是病毒程序的第一部分，它得到控制权后修改内存可用空间的大小，在内存高端辟出一块区域，并把第一部分移至该区，接着读入放在磁盘"坏簇"中的第二部分，并和第一部分拼起来，使病毒程序全部驻留在内存的高端，然后修改INT13H的中断向量或其它中断向量，使其向高端的病毒程序，这时即可把原引导程序读到内存中，并把控制权交给它以完成系统的启动。
