在实验上

The system includes the dual-tone multifrequency signal detection module,the musical sound processing module,the harmonical analysis module of circularity and many other demonstration modules.

以前的实验项目多是在微机上仿真演示，学生兴趣不大，实验教学效果不理想。购买现成的仪器设备，投入大，维护不方便，学生亲自设计操作机会少，动手能力难以提高。

As for the ester exchange reaction on phosphorus, it was found that N-phosphoryl histidine the fastest one among all of the N-phosphoryl aminoacids. The results studied by MNDO method indicate that due to theparticipation of imidazole group, the formation of hexa-coordinatephosphorus intermediate made the iso-propoxyl which is opposite toimidazole group more active than the other ones and much easier to leave.When iso-propoxyl left, a new penta-coordinate phosphorus intermediate wasformed, and it is sterically favorable to be attacked by an alcohol from theopposite direction of imidazole.

对于磷上酯交换反应，实验中发现N-磷酰组氨酸反应速度明显高于其它N-磷酰氨基酸，理论研究表明，侧键咪唑基参与下六配位磷中间体形成后，位于咪唑基对面的异丙氧基反应活性大大提高，即从咪唑基的对面位置发生异丙氧基的离去和另一分子醇的进攻，在能量上和空间上都是有利的。N-磷酰丝氨酸的磷上酯交换反应有着类似的特点。

Also, thanks to a collaboration with Prof. Susumu Tonegawa, we are able to probe questions of synaptic plasticity in vivo at the physiological and behavioral levels, by creating mice overexpressing or deficient in particular genes.

同时要感谢在Susumu Tonegawa教授的共同合作下，让我们对于老鼠生理上与行为上和突触可塑性相关的问题，得以在活体实验上研究特定基因的过度表现或缺乏。

The critical heat fluxes in narrow channels are experimentally investigated in the present study.

本文在实验的基础上对窄缝通道中液氮的临界热流密度进行了实验研究。

Such experimentation requires money, and the United States government has funnelled funds for drug experiments through different agencies, both overtly and covertly.

这样的实验需要经费，而美国政府在药物实验上花费不少，通过不同的代理机构，包括公开的和隐蔽的。

Wave statistic and spectrum, characteristics of flow field under shoaling irregular waves are investigated.

对斜坡床面上不规则波浪要素及其作用下底部的流动特性进行实验观测，对波高进行统计分析和谱分析，在实验数据范围内得出斜坡上不规则波浪要素与谱的关系表达式，同时对浅化作用下不规则波浪的流动特性进行统计分析和谱分析，得到了浅化作用对不规则波浪的波高及底部流动特性影响的规律。

At first glance, his work is nothing too complicated: paint, texture and colour on canvas, occasionally on paper, and more recently transposing his experiments with pure form and mechanical colour to digital and electronic media.

乍看上去他的作品并不算太复杂：不论是在油画布上或偶尔在纸上呈现的颜料，质感和色彩，还是最近以来把纯粹形式和机械色彩转移到数码或是电子媒介上的实验。

On this platform, we can carry out basic experiments like LED digital pipe display, keyboard scanning, electric music, Serial Communication, etc.

在实验平台上可以进行LED数码管显示、键盘扫描、电子音乐、串口通信等基本实验。

In the "indirect" process, first observed in neutral kaon particles in 1964, quantum mechanics allows particles to change into their antiparticles and back again in a process known as "mixing". In 2001, The BaBar team, working at the Stanford Linear Accelerator -- and independently the Belle collaboration at the KEK laboratory in Japan -- were the first experiments to detect this in a B meson. BaBar observed "direct" CP violation in 2004 by showing that the number of decays observed for B mesons was higher than for their antiparticle equivalents.

在&间接&过程中，量子力学允许粒子在一种被称为&混合&的过程中，在自身与其反粒子之间相互转变。1964年人们第一次在中性K介子上观测到这种现象。2001年，在斯坦福直线加速器中心工作的BaBar研究组和另一个日本高能加速器研究中心的Belle研究小组各自独立地第一次在实验中观测到这种现象发生在B介子上。2004年，BaBar小组观测到了&直接&电荷宇称不守恒，他们发现观察到的B介子的衰变数量要高于其对应的反物质。
