在实验上

This method of teaching reform has yielded the good results and is welcomed by the students.

化学是建立在实验基础上的科学。因此，在重视化学基础理论教学的同时，必须强调化学教学的实践性。

This process is quite different from the role of exciton blocking, and can be used to explain the results we obtained.

我们从实验上证实了激子在界面被有效拆分的物理过程的存在并对界面拆分激子对测量结果的影响进行了估计，并据此提出了在设计高效有机太阳能电池中应该注意的原则。

In the structural studies on polysaccharides, we found that there was a serious error in a method that has been used to analyze the glycosyl residue compositions of acidic polysaccharides.

在多糖的结构研究中，我们发现以往常用于分析酸性多糖糖残基组成及其比例的两步水解法，不仅所得结果误差很大，同时在实验设计上存在严重缺陷，容易误导多糖的结构分析及构效关系研究。

We will look at the business of producing your program in the laboratory section of this course.

在这一节我们将关注在实验课上你编写程序时的一些事情。

In the early stage of experiment, an in-material thin film manganin gauge was studied. This in situ gauge was manufactured by single-step thin film processing, namely, manganin piezoresistance element was prepared on inorganic substrates such as ceramic, microcrystalline glass, etc by sputtering.

在实验的初期，本文还研究了&在位式&的锰铜薄膜传感器，即首先在陶瓷或微晶玻璃基板上沉积锰铜敏感元件，然后用粘贴PTFE薄膜的方法完成传感器的封装。

And the possibility of using this mothod to measure the grain size on line was discussed.

实验结果表明，这种方法操作简单，能够准确测量在一定尺寸范围内的板材的晶粒尺寸，并与背散射电子衍射结果进行了比较，探索了用X射线面探测器衍射系统在工业上进行金属板材晶粒尺寸在线检测的可行性。

Based on these problems, this paper makes street lamps intensive manage system for example and desigrs a communication system based on direct sequence spread spectrum modulation and demodulation technology on power line, and aims at the problems which emerged during tests brings forward resolvents.

基于上述问题，本文以城市路灯远程集中管理系统为例，开发了能够实现在低压电力线上传输数据的扩频数字传输系统，并针对在实验中暴露出的问题给予简单分析、提出了解决方案。

Can reverse JA-induced migration inhibition JA-treated cells also showed significantly higher adhesion to laminin In conclusion these results indicate a novel anti-tumor role of JA via reducing reorganization of cytoskeleton increasing integrin 3 expression and adhesion ability to inhibit tumor cells migration Furthermore immunofluorescence staining of phalloidin/actin indicated that JA-treated cells exhibited cytoskeleton rearrangement and significant decreases in the number and length of filopodia Activity of Rho-family small GTPases was detected by a GST-pull down assay and showed that GTP-loaded Cdc42 and Rac were decreased in JA-treated cells In the future we hope these findings will be helpful to further understand the mechanisms underlying tumor progression in oral cancer and subsequently improve the cancer prevention and treatment

以抗体阻断integrin ？3可以有效使OC2恢复被JA所抑制的迁移能力。细胞贴附实验指出JA能提高OC-2在laminin环境下的贴附能力。当我们进一步以免疫萤光染色观察细胞，发现在JA处理下的OC-2，其外形、细胞骨架和细胞边缘的filopodia的密度和长度明显减少，利用GST-pull down assay侦测到Cdc42-GTP和Rac-GTP的表现量降低。推论爵床素A可能透过刺激口腔癌细胞大量表现integrin ？3，使细胞贴附能力增加或是透过改变细胞骨架来降低细胞迁移能力。希望本研究对於JA所做的抗癌及抗转移效应评估能提供口腔癌治疗在研发上一些帮助。

The characteristics of this device are of high swing,high measuring precision of balance and reliability in test data.

因此，在动态导数测量实验中主要是测量作用在模型上的气动力和气动力矩的信号，以及模型振动的位移信号。

In simulation, we use the software called "BeamPROP 5.1" by "RSoft Design Group" to study the wave propagation in the tapered fiber and calculate the monitored power, mode profile, contour map…etc.

在模拟实验上，我们利用R-Soft公司出版的BeamPROP 5.1这套软体进行模拟。我们观察到波在拉伸光纤中的传播特性，并且讨论波经过拉伸光纤后的功率、电场分布型态、电场的等高线图…等。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
