实验

Chemistry experiment is chemical learners must do, but many experimenters in the experiment there is a failure in the process of this phenomenon.

化学实验是化学学习者必须要做的，但不少实验者在实验过程中存在着失败这一现象。

In the experimental process, we made comparison from feature extractions and resolutions. The experimental results show the effectiveness of the proposed method in this thesis

在整个实验过程中，从特征提取和分辨率两个方面作了实验对比，实验结果证明了本文所提出方法的有效性

By analyzing and handling the experiments results, we obtained the rules of change of hydrodynamic characteristics of the cycloidal propeller in the pitch ratio varying from 0.2π to 0.75π and the steering angle varying from -90°to 90°, such that a foundation has been laid for using it in practice, and for setting up the theoretical calculation method of cycloidal propeller.

一、通过分析摆线推进器的工作原理，设计并加工了实验模型和实验装置，在哈尔滨工程大学船模水池对该模型进行实验，经过合理的理论分析和数据处理，获得了螺距比从0.2π到0.75π，方向角从-90°到90°范围内的水动力变化规律，为建立摆线推进器水动力性能理论计算方法和工程应用奠定了基础。

The results showed that the hypoglycaemic and the urine glucose lowering effect of PCE-C in alloxan-diabetes rabbits were excellently and long-lasting. PCE-C could also reduce the serum total cholesterol and the serum triglyceride in experimental rabbits to normal level, and delay the loss of body weight of the rabbits. The glycosylated hemoglobin is the true index that reflects the long-term controlling effect for diabetes, and the experiment result affirmed the veracity and reliability of the results of the blood glucose.

结果表明，PCE-C对实验家兔血糖和尿糖的降低效果具有高效性和持续性；当血糖控制不良时，可并发血脂水平的升高，PCE-C可以使血清总胆固醇和甘油三酯恢复正常水平，同时能减缓实验家兔的体重下降；糖化血红蛋白是真正反映糖尿病长期控制效果的指标，PCE-C对实验家兔GHb的作用影响充分证实了血糖测定结果的准确性和可靠性。

Side-stream experiment for the removal of sec-butanol from recycle butylenes by adsorption on adsorbent PUMS-01 was carried out in a methyl ethyl ketone unit.

对甲乙酮装置循环丁烯脱除仲丁醇吸附剂PUMS-01进行了工业放大实验，实验结果表明产品性能达到了小试实验的水平。

Before and after the exposure to environmental magnetic field in minesweepers, the crewman's ECG,ICG, pulmonary function, oxygen saturation and rheoencephalogram s were examed.

对参加同步扫雷实验的艇员在实验前和实验后进行心电图、心阻抗、肺功能、血氧饱和度和脑血流图检查。

This paper introduced the reform goal of the experimental teaching of legal medicine course,and its corresponding guiding idea and principal experimental contents.

通过对法学专业的法医学课程实验教学改革的尝试，介绍实验教学改革的目标、指导思想与主要实验内容。

In the course of educational experiment on the synthesis of non-ionic surfactant, in order to reduce the depletion on ethylene oxide and save experimental cost, an educational experimental device with the function of enduring highpressure and little reaction mass was constructed by refitting a 250mL high-pressure reactor. In order to verify the function of the experimental device, lauryl alcohol polyoxyethylene ether was synthesized by it.

在非离子表面活性剂的合成教学实验中，为了减少环氧乙烷的消耗，节约实验成本，对250mL的高压反应釜进行了改造，筹建了一套耐高压反应物料量少的教学实验装置，并用此装置合成了十二醇聚氧乙烯醚，以验证此装置的性能。

This do not make of regressions toward to positivism,but forming a new ...

这并不构成向实证主义的回归，而正在构成新的实践优位的科学实践哲学研究进路；给出对观察/实验与理论各种复杂关系的一个初步分析，观察/实验的确与理论的关系在不同阶段、有不同的特征和变化，不同品格的观察/实验与理论有不同的关系；不能以一个普遍的命题勾勒它们之间的关系。

The motor can accelerate and slowdown normally,which proves the feasibility of this kind of superconducting motor.

最后，在几种不同实验装置和实验条件下进行了超导电机的旋转驱动实验。
