The variables in controlling the flow of microfluids are voltage and time. This study adopted the method of fast measurements、so time taken for applying voltage did not exceed ten minutes. If voltage is not carefully controlled、the microchannel may be damaged at the particle flow. During measurement、a buffer fluid with a concentration of 0.1 M was used、the current was sufficient to propel the magnetic particles through the microchannel without damage from excessive voltage. The maximal amount of microfluid particles at the junction of the separation and injection channels was obtained with a time of 5 mintures and voltage of 200V.

藉由改变不同的电压和时间来观察颗粒在微流体中的移动情形，由於这个研究是以快速检测为原则，所以将时间控制在10分钟之内；在电压的控制上面如果电压太大的话将会对微流体的管道造成损伤，降低微流体装置的寿命，并且也有可能会对里面的颗粒造成影响，所以缓冲液的浓度使用比较大的0.1 M，这样所产生的电流将足以推动磁性颗粒并且电压不会太大也不会造成管壁的伤害。

However, after I came to understand distance education more deeply, I find that network distance continuation education has many advantages. Firstly, it breaks through the limitation of time and distance. It enables the students all over the country to get instructed from those top level teachers, take the most advanced teaching method, and enjoy richer education information resource. Secondly, it profits in extending the teaching scope, providing more education chances and more flexible way of learning, which make it possible to let more people accept education. Thirdly, the modern network distance continuation, which is based on information, offers a good space-time platform for a lifelong learning. At last, the modern network distance continuation makes students to focus on self study, which help them to fully develop their proactivity, intuitivity and creativity. For the four reasons mentioned above, finally, I chose network distance continuation education as the way of my further education.

但是，经过深入了解之后，发现远程网络继续教育是有很多的优势的，第一，它可以突破时空的限制，使全国各地的学生都能接受一流水平教师的教导，接受最先进的教学方法，享有更丰富的教学信息资源；第二，有利于扩大教学规模，提供更多的学习机会和更灵活的学习方式，使更多的人可以接受教育；第三，以基于信息技术的现代远程网络继续教育，为终生学习的实现提供了时空平台，为人们提供更多开展的实施终身学习的机会；第四，现代远程网络继续教育以学习者自学为主，充分发挥学习者自主学习的主动性、积极性及创造性，综合以上四点，我最终选择远程网络继续教育作为我继续学习的途径。

Compose the text of the Mango Street, bit by bit, and sometimes the records of the real people can not help but to give too much sympathy, for example: Rosa Fargas his wife has tired all too many children the time from buttoning and bottling and babying extent that she has no way to care for them, one of them exploded down to earth without even an "oh", or if the pursuit of love Sally really find love later, but off In another cage. But even if Latinos in the United States had very hard work, the book is still showing a better vision for the future and hope.

文字中抒写着芒果街的点点滴滴，有时候真实的纪录却又让人忍不住给予太多太多的同情，例如：罗莎法加斯太太孩子太多又tired all the time from buttoning and bottling and babying以致于她没有办法去照顾他们，one of them exploded down to earth without even an&oh&，又或者追求爱情的萨丽真的找到爱情以后，却又关在了另一个牢笼。

The real-time PCR used SYBR GreenⅠsystem as control group to compare semi-quantitative PCR system. When detecting a lot of samples, semi-quantitative PCR system could separate them from more than 7% or less than 3% to decrease the numbers of samples for quantitating by real-time PCR.

实验同时使用real-time PCR之 SYBR Green Ι法作为对照检测系统，以此系统与半定量PCR检测系统比较，於大量检测样品时，可将样品初步区分基因转殖含量低於3%及高於7%，以减少必须使用real-time PCR定量之样品数，进而可缩短检验的时间及降低检验所需费用。

Many falconers practically hold a party to ensure that this period of time is fully taken advantage of. The bird is not allowed to sleep for an extended period of time, usually more than 24 hours as the sleep deprivation helps the manning process.
