Methods: The sample consisted143 children which were in early permanent dentition of ClassⅡ,Division 1malocclusion .Pre-and post-treatment study models were assessed using PeerAssessment Rating index. According to the outcome of treatment, thesecases were classified into three types as "worse, no different","improved"and"greatly improved". The cephalometric analysis and Model Analysis werepreformed with pretreatment lateral cephalograms and study models for"improved"and "greatly improved"cases."T"–test was assessed to find out thesignificant difference between the extraction and nonextraction, and the resultsincluding age factor were analyzed by stepwise discriminant analysis.

应用PAR 指数对矫治前后的143 副恒牙早期的安氏Ⅱ类1 分类错牙合患者牙牙合模型进行评估分析，按矫治结果等级分为三类A、变坏或无改善，B、改善，C、极大改善，然后将B、C 两类患者矫治前的头影测量片及模型分析数据按拔牙与未拔牙进行成组t 检验的单因素分析，找出两组间有显著差异的软硬组织和牙牙合模型指标，对这些指标合并年龄因素进行逐步判别分析。

The institution change is that vegetable can circulate freely around the whole country after 1985,since every province take the same policy after 1985,it did not consider this factor in the model and consider the technology and market effect on production concentration mainly,and it specified to these indexes,that is the use of plastic film,the amount of retail market and total amount of society retail consumables,the road mileage,per GDP,nonrural employment opportunity,irrigated area,the vegetable plowed last year.

蔬菜是一个大的分类，不同品种在单产、产值、品质等方面都存在较大差异，基于数据所限，前文对于全国和山东的分析忽视了蔬菜的这种特性，为弥补这一缺陷，本文通过对山东蔬菜主产市重点乡镇的实地调查，来验证蔬菜产地集中的趋势，更详细的描述出蔬菜集中以及不同品种的集中，调查结果也表明，市场条件、政府支持和交通条件是地方官员最为认同的导致蔬菜产地集中的原因。

Preliminary data on speech effect of STN-DBS on five Chinese Parkinsonia patients were demonstrated. Inconsistent outcome of the performance suggests that future study should include subject selection criteria such as with/ without medication, longterm effects, as well as larger sample size.

本研究提供国内视丘下核深部脑刺激手术对巴金森氏症患者言语成效初步数据，虽然五名患者在言语运动轮替、构音位置与强度、口语流畅度、嗓音功能呈现不同程度改善状态，但是患者间表现差异大，未来研究需考量病患条件与分类，术后时间一致性、药物使用、大样本等因素。

The new representation proposed in this paper deals with the partitional clustering problem by regarding it as a multi-objective optimal problem; in this approach the niche Pareto genetic algorithm is used to solve the problem.

动态聚类算法从本质上讲是单目标组合优化算法，一般需要事先给定目标分类数和初始聚类中心，且初始聚类中心的选择对数据划分结果影响较大。

Occurrence records from 1864 locations and 34 environmental variables from Daymet datasets were gathered, four modeling methods including Logistic Regression, Classification and Regression Trees, Genetic Algorithm for Rule-Set Prediction and maximum entropy method were used to generate potential geographic distributions for Dreissena polymorpha in the continental USA. Then three statistical criteria including area under the Receiver Operating Characteristic curve, correlation and Kappa were calculated to evaluate the performance of the models, followed by analyses of major variable contributions.

论文以1864个美国外来入侵物种斑马纹贻贝定点发生数据和开放式基础地理信息数据库Daymet的34个环境变量为主要信息源，采用逻辑斯蒂回归、分类与回归树模型、基于规则的遗传算法、最大熵法4种途径，建立美国大陆部分潜在生境预测模型，从接受者运行特征曲线下面积、Pearson相关系数、Kappa值3个方面来检验模型预测精度，在此基础上分析斑马纹贻贝的空间分布规律及其环境影响因素。

Network address navigation, although also go to the lavatory, but some functions are singler, cannot satisfy the requirement of the user, basically be to classify insufficient clarity, contain data less also.

网址导航，虽然也方便，但有些功能还比较单一，无法满足用户的需求，主要是分类不够清晰，容纳数据也比较少。

A typical way to classify data stroage media is to consider its type and shape of movement (or no-movement) relative to the read/write devices of the storge apparatus .

数据存储器分类的方法首先是要考虑它们的型号和形状，读写可行性。

In the course of program designing, OLE mechanism and Graph for Windows have been used to generate specific geological triangular chart from computer instead of manual work in before. By using PowerBuilder 7, inquiry through a clue of combination of conditions including structural tree, strati graphic tree, well number tree and sample number tree is realized, which meets the thinking way of geologists.

在程序设计方面，针对岩石名称分类复杂、量化定名烦琐的现状，采用OLE机制和Graph for windows图形工具，对岩石含量数据进行相对数值转换，完成了平面上呈三角形排列的三个直角坐标系统的叠加，避免了人工绘制地质三角图随意性大、精确度低的问题，极大地提高了工作效率。

Some defects of current classification algorithms are tided over by this new algorithm.

ID3算法 [2 ]和 C4 。5算法 [3]是较早提出的两个著名的数据分类算法。

Topics cover a wide range of payroll policiesand procedures regarding wages / salaries / bonus / commission etc., time sheet / timecard, sick / personal / annual leave / long service leave / leave loading, superannuation, PAYG tax withholding, salary sacrifice, payroll tax, PAYG payment summary (formerly called Group Certificate), award application and interpretation (Employment Contract, Federal Award/State Award, EBA, CA, AWA) etc.

这一部分全面讲解澳洲目前的工资系统和工资处理，包括工资的组成和分类，怎样建立和输入原始工资数据，澳洲的工资制度(有关工资的Award， salary package， pay rate，p/t， f/t， temporary / permanent / casual work etc。)的各种规定， PAYG税的扣缴，病假/年假/个人假/长期工休假等方面的工资处理，养老金的核算和缴纳，工资规划，工资税，年终雇员工资汇总表等等。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
