Not every subgroup of a D-group is also a D-group. If a subgroup is a D-group we call the subgroup "sub- D -group." The "commutator ideal" of G is the smallest sub-D-group containing its commutator subgroup. We found that the commutator ideal can be viewed as a finitely generated module over a ring when G is a finitely generated metabelian D-group.

并非每个子群都是一个可除群，若一个子群是可除群，我们称之为子可除群(sub-D-group)，而G 的交换子理想则是在G中包含其导出群的最小子可除群，我们发现当G是一个有限生成亚交换可除群时，其交换子理想是一个有限生成模。

On CHE programming, the higher coupling ratio of control-gate makes the higher electrical field across TOX in Si than Ge. Also because of the continuity of displacement vector, the higher permittivity of Ge would cause the lower electrical field at interface. We get the higher gate current in Si than Ge. On CFN programming, the higher CT in Ge would show the higher electrical field across TOX. However, the parameters of F-N tunneling are calculated and showing the gate current in Si is larger than Ge. On the same mechanism of F-N tunneling erasing, the parameters also show the higher electrical filed of Si would cause the higher erasing speed. The continuity of displacement vector also explains the higher electrical field at interface for F-N tunneling programming/erasing.

从通道热电子穿隧写入的模拟结果发现，由於控制闸极耦合电容的影响，加上电位移向量在半导体-氧化层界面连续的观念，拥有较高介电常数的锗反而得到较小的等效电场，决定了穿隧电流反倒是不如矽基板；在F-N穿隧写入的模拟中，即便锗基板拥有较大的总耦合电容，使得在浮闸的耦合电压大於矽基板，但仍旧是半导体-氧化层界面的电场扮演了穿隧电流的决定性因素，得到的结果仍旧是矽基板的写入速度高於锗基板；在F-N抹除的模拟中，运用与F-N写入相同的数学模型，仍旧看见在锗基板上未能得到速度上的改善，同时用数学的计算展示了合理的解释。

2There are differences between China's best young football coaches in terms of age, seniority, education, marriage, coaches level, nature of work, the nature of work units, regions, eat. In which older and younger age with higher satisfaction, which is into "U" type ;In seniority, the lower academic qualifications, the higher job satisfaction, showing the antigrowth trend. Level in the coaches, the higher the level on the career identity and career development with lower satisfaction, and other dimensioned showed positive growth. In marriage, unmarried outstanding youth football coaches have higher satisfaction in career identity dimensions. In the nature of the work, the coaches satisfaction is higher, but the degree of salary is lower. Nature in the workplace, the youth football coaches in large-scale enterprises outstanding football club are with higher satisfaction. At the district level, the developed coastal regions are with higher job satisfaction, the old industrial base in the northeast have lower job satisfaction in the work environment and salary degrees. regard to remuneration, salaries in 2000-3000or more than 5000 outstanding young football coaches have higher job satisfaction in the current, but salaries in 3000-4000 or 4000-5000 outstanding football coaches, the job satisfaction is slightly lower三、There is significant positive correlation between job satisfaction and job involvement of China's best young football coaches.
