The applications of PESA's scale inhibition property in several fields, so we use differert experiment methods to test the scale inhibition of PESA.

鉴于对阻垢剂的需求和阻垢试验方法随应用领域的不同而有很大差别，因而对PESA的阻垢性能的研究采用了不同的研究方法。

It had been found that when the relative molecular weight changed, the properties changed also. When the relative molecular weight of PESA is in the range 800 to 1000, the scale inhibitions are best. When the relative molecular weight of PESA is lower than 700 or higher than 1000, the scale inhibition becomes worse.

采用鼓泡法研究了PESA的阻垢性能与其相对分子质量的关系，发现当PESA相对分子质量变化时，其性能变化相当大，当相对分子质量在800～1000范围时，钙离子稳定浓度达到120 mgL1以上；当相对分子质量低于700或高于1000时，阻垢性能变差。

METHODS 40 cases patients with OSAHS were performed the operation of uvulopalato pharyngoplasty, and the Calgary Sleep Apnea Quality of Life Index questionnaires were completed before and after operation three months later, then health-related quality of life were compared in daily functioning, social interactions, emotional functioning and symptoms, the total scale is the sum of the average scale of each domain.

选择40例行悬雍垂腭咽成形术的OSAHS患者，采用Calgary生活质量指数在术前及术后3个月进行问卷调查，从量表中的日常活动、社会活动、情感及症状4个方面比较与健康相关的生活质量，各部分的平均分相加即为量表的总分。

For chemical processes, focus is on the relation between the added concentration and the anti-scale effect of acidification, inorganic phosphate and organic phosphonate and comparing the anti-scale effects among different kinds of chemicals.

对于化学阻垢技术，着重点放在研究酸化、无机磷酸盐阻垢剂及有机膦酸盐阻垢剂的投加浓度与阻垢效果的相关关系，并且比较不同阻垢剂的阻垢效果的差异。

Four sets of actual aerial photos are used to test;which are at different scale and in different terrain.The empirical results verify that image elements of exterior orientation obtained by a POS can satisfy the accuracy requirements of topographic mapping,no matter which scale and terrain the empirical block is classified to.However,to satisfy the accuracy requirements of object point in elevation,the accuracy requirements of exterior orientation elements are at least one time higher than that in planimetric mapping.

通过对摄自不同地区、多种摄影比例尺航摄影像的实验表明，由POS系统获取的影像外方位元素进行安置元素测图完全可以满足各种比例尺、不同地形图测绘的精度要求，但为了满足地物点的高程精度，对影像外方位元素的精度需求较用于平面测图时的至少要高出一倍以上。

Results: Although some of the patients acquired scores of intelligence within the normal and borderline range, both of their Full-Scale IQ and Sub-Scale IQ scores were significantly lower than their premorbid levels, showing adverse effects on different aspects o...

结果：部分脑外伤者的IQ值虽在正常或边界智力水平，但他们伤后的总智商或分量表智商显著低于伤前智商（P＜0.05），表明这些患者在脑外伤后存在着某种程度或某方面的智力受损。

Patients were assessed radiographically at 6, 12, and 52 weeks and at 2 years if needed. Clinically, patients were evaluated with the visual analog scale, Neck Disability Index, Short Form–36, and a modified Prolo Scale.

通过X 线检查来评估患者在6、12、52周和2年后的疗效，在临床上，我们是通过直观类比标度、颈部疾病指数、短型－36和改良序列刻度来评估患者疗效的

This means that modeling can be realizably applied to make the optimal operation schemes regardless of pilot-scale and/or full-scale experiments.

这表明，在很大程度上数学模拟技术可以替代中间或现场试验，从而被用来诊断运行问题、并制定工艺运行优化策略。

The growth of economic scale is affected by many facts, but the resource constraint is the important matter, its shortage or reasonless collocation will restrict the growth of economic scale.

经济规模的增长受诸多因素的影响，其中资源的约束对经济规模增长的影响越来越突出，资源的稀缺或者不合理的配置都会对经济规模的增长产生很大的约束。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。
