The series in which the order of the terms is to be arranged.

如果有同种类的许多等式，就应该化简到一个等式，也就是说，化简到在连续比例中量的系列里只有少数项，换言之，在此系列中，项目的秩序被安排好了。

The testing, answering system was developed out by the ASP.net. Two test papers were abstracted from the system by the combination of the certain proportion and binominal distribution mathematical models stragety. The two test papers were tested by 52 students through the cross design. The difficulty and discrimination of items and the reliability and validity of the test papers were worked out with Education Statistics, factor analysis, relative analysis etc.

运用ASP.net技术开发了组卷、答卷、阅卷系统，应用重点等级定额比例分配与难度等级二项分布数学模型相结合的组卷策略随机抽出2套试卷，采用交叉设计对52名预防医学本科学生进行测试，用教育测量学原理、因子分析、相关性分析等方法分析两套试卷试题的难度、区分度和试卷的信度、效度。

Cronbach a of them equals respectively 1.000, 0.714. Conclusions The system could form the test pater with the strategy of the combination of the certain proportion of the important degree and the binominal distribution models which realized the Internet testing, rectifying and analysis.The test papers abstracted from the system were reliable and valid. It can scientificly, objectively evaluate the students' ability and it's beneficial to deviation of the teaching, testing and controlling testing cheat. The Non-paper testing system has good practical value.

建立的试题库和考试系统能够按重点等级定额比例分配与难度等级二项分布模型策略组卷，实现了远程考试、自动阅卷和相关分析功能；从该系统抽取的试题难度和区分度合适，试卷可信、有效；能够客观、公正、科学地测试和评价学生的能力，对开展教考分离、控制考试作弊起到积极作用，具有较好的实用价值。

These suggest that Pinus massoniana, the pioneer species at early succession stage of forest community, is the plant species adapted to high light intensity, while Cryptocarya concinna, a species at succession climax stage has an advantage in light utility under low light environment.

这说明群落早期演替的先锋树种马尾松属于强阳生性树种，具有适应强光的特点，而处于群落演替项级阶段的优势种黄果厚壳梓则能更加充分利用低光生长环境中的光强，同时也可通过提高电子流向光呼吸分配的比例来避免自然光环境中强光的伤害。

In another cadaveric study, Adams and Hutton58found that the lumbar facet joints resist approximately16% of the intervertebral compressive force when standing erect versus near 0% when sitting, which helps explain the high intra discal pressures during unsupported sitting.59 Finally, after conducting in vitro experiments measuring induced loads on cadaveric lumbar facets, Lorenz et al.60 concluded that with increasing compressive loads, the absolute facet loads increases only slightly, so that the proportion of the axial burden borne by the l-z joints actually decreases with increasing stress.

另一项尸体标本的研究中，Adam和Hutton发现，当直立站立时，小关节承担了逐渐压力的近16%，而坐位时进0%，这解释了为什么在无支持的坐位时椎间的压力非常高。最后，Lorenz在尸体标本加载负荷后测量小关节的应力后，认为增加压力负荷时，小关节间的应力仅轻微增加，因此在轴向负荷中，小关节承担的比例实际随着应力的增加而减少。

The following data were obtained and compared between resistance and responder: white blood cell,neutrophil,hemoglobulin,C-reactive protein,erythrocyte sedimentation rate,albumin,and lactate dehydrogenase.Male patients with decreased albumin may be related with resistance,but they could not be good predictors of resistance.

川崎病患儿发生IVIG耐药的可能危险因素有外周血白细胞、中性粒细胞比例、血红蛋白、C反应蛋白、血沉、血浆白蛋白、乳酸脱氢酶等，分析结果提示血浆白蛋白降低及男性可能与IVIG不敏感川崎病有关，但仅此两项指标尚不能预测IVIG不敏感川崎病的发生。
