养肝抗癌丸联合TACE疗法能够有效地抑制或减轻TACE疗法导致的毒副反应，保护和改善中晚期原发性肝癌患者造血功能和肝细胞功能，拮抗TACE导致的肝纤维化损害，延长患者的生存期，提高生存率和生存质量，治疗中晚期原发性肝癌的综合疗效优于TACE疗法。

Therefore, as to the reason of the formation of Chinese society in Southeast region of China, especially the prevalent hypothesis that Hakka in the abutted region among Min, Yue and Gan was from Central Regions, a possible explanation may be that, after the large-scale turbulences in the abutted region among Min, Yue and Gan had been appeased in Ming dynasty, social reorganization occurred in this region. just at this stage, the groups of the region went through a re-choice to the ethnical identity, these choice affected the ethnohistory or writing of groups since middle period of Ming dynasty.

因此笔者认为，对于中国东南汉人社会的形成，尤其是闽粤赣毗邻区的客家人普遍的中原南来说盛行的一个可能的解释是，在明代闽粤赣毗邻区大规模动乱平息之后，闽粤赣毗邻区处于社会重组的阶段，正是在这一阶段，其人群亦经历了一次族群身份确认的过程，而这影响了明中后期以后长期的族群撰述，反映在闽粤赣毗邻区的地方文献中，则是对畲民典范书写的确立，它反过来又约束了人们对族群的选择与改造。

However, this usefulness of GaN for optoelectronic devices seens to be limited by the fact that the defficulty in obtaining p-type material is to grow crystals by admixing GaP to GaN. As will known, GaP with n- or p-type conductivity can be easily obtained by suitable doping. Thus, it might be possible to get n- and p-type GaP_(1-x)N_x or GaAa_(1-xN_x crystals above some critical P content of the alloy system.

把两种或两种以上材料组合起来实现优异性能材料的方法是一种经常使用并行之有效的方法，本论文就是对GaP、GaAs与GaN形成合金系GaP_(1-x)N_x和GaAs_(1-x)N_x进行基础性研究的结果，人们预测这种合金系的禁带宽度应在磷化镓的2.261eV(或砷化镓的1.43eV)到氮化镓的3.39eV之间，如果能制成上述合金系则是很有意义的，它是很有希望的蓝色发光材料。

The growth mechanism of these GaN nanomaterials was proposed and discussed based on the investigation of the influence of the ammoniating temperature, ammoniating time and the Nb films'thickness on the properties of GaN nanosmaterials.

通过研究不同生长条件对制备一维GaN纳米材料的影响，初步提出并探讨了采用此方法合成一维GaN纳米材料的生长机制。
