Alternation of generations can be divided into two basic types, one for the same shape alternation of generations, the sporophyte and the gametophyte in the morphology similar size, only cytology and physiology are different, such as Ulva, etc.; another type of shape alternation of generations, that is, in the sporophyte and gametophyte morphology and size are also significant differences.

世代交替又可分为两种基本类型，一为同形世代交替，即孢子体和配子体在形态大小上类似，仅在细胞学上和生理上有所不同，如石莼等；另一类型为异形世代交替，即孢子体和配子体在形态结构和大小上也有明显差异。

In our research, the genetic identity of 7 populations of 2 species Ambrosia calculated by the Nei method showed that were very similar and above 0.909 in every population.

The ariability in amoebocyte concentration in the field does not seem to be linked to any of the factors considered in this study; it appears to reflect mostly an inter-indiidual ariation rather than seasonal fluctuations.

在研究中阿米巴的浓度在大田条件下没有与任何一种环境因子有关，看起来它受个体之间差异的影响比季节的变化更大。

DNA content of tumor cells was determined with flow cytometry in surgical samples from 36 patients, with esophageal carcinoma. The aneuploid was found in 25 cases (69.4％).

本文用流式细胞检测了36例食管癌切除标本的DNA含量，结果发现，DNA倍体水平差异较大，范围为1.68C～8.16C，大多数食管癌为非整倍体DNA含量，其中少数病人在同一标本中同时发现两种不同的非整倍体。

The patients were treated with routine manipulation(group A,30 cases) and PMWL(group B,30 cases) respectively.The difference pain,function,range of active anteflexion,anteflexion strength and satisfaction degree of patient were analyzed according to UCLA scoring system after one period of treatment score.

分为2组，分别采用常规治疗和杠杆扳法治疗，每组30例，在治疗1个疗程(10次)后利用UCLA进行功能评分，比较两种治疗方法在疼痛、功能、主动前屈活动、前屈肌力及患者满意度方面的差异。

The difference pain,function,range of active anteflexion,anteflexion strength and satisfaction degree of patient were analyzed according to UCLA scoring system after one period of treatment score.Results:The pain,function and satisfaction degree of patient after treatment got better than those before treatment in group A(P.05);the active range and anteflexion strength had no improvement.

分为2组，分别采用常规治疗和杠杆扳法治疗，每组30例，在治疗1个疗程(10次)后利用UCLA进行功能评分，比较两种治疗方法在疼痛、功能、主动前屈活动、前屈肌力及患者满意度方面的差异。

Objective: Study on several kinds of regulative alcohol metabolits in comparing the different effects of antialcoholism.
