查询词典 DMA

It consists of same three sets of acquisitive circuits,which construct O-shaped structure to sample the signals without drop .And it adopts threshold judging method to determine the valid data in the process of the acquisition,abandons vast of the redundant useless data at the same time,it only sends the useful data to the host computer by the way of DMA,so it is easy to processing the data.The design is concise and reliable.

但这本身也是一对矛盾，因为随着采集速度的提高，单位时间内采集的信号数据也就越多，而一般的采集卡在采集一定数量的数据后，总的需要一定的时间向主机内存传送数据，而在这段时间内是不能采集数据的，作为随机信号，如果在此时间内到来，则会造成信号的丢失。

The CP15,CP15/60 and CP23 on the sporozoites of Cryptoporidium parvum are major surface protein which are studied in the new pattern vaccine and developed a serologic detection method for cryptosporidiosis.In the experiment,prokaryotic and eukaryotic expression vectors of three genes were constructed by recombinant DMA technique and expressed in E.coli and Hela cells respectively.

微小隐拘于虫（pSporndum pMum，Cp）子抱于表面蛋白 CP15、CP15／60和CP23是微小隐抱子虫主要的表面抗原，它们既是人们研究隐抱于虫新型疫苗的主要对象，也是建立隐抱子虫血清学检测方法的首选抗原。

In the first part of this thesis, Stress relaxation method set up in the software of DMA was used to perform the aromatic and aliphalic (D2192-BAPP) PI film stretching process. To study the optical anisotropies property to the light leakage from the crossed polarizers, we put the stretched samples into one set of crossed polarizers and as expected, the stretched PI films could reduce the light leakage at view angle of ±45 deg, and exhibited a visually observed compensating property of an A-plate. No color shift wasobserved, and the birefringence was very uniform. These results prove a uniform birefringence can be obtained by a stretched process for PI films.

首先，我们以动态机械分析仪的应力缓和模式对芳香族FDA-BAPP PI及脂肪族D2192-BAPP PI薄膜进行拉伸实验，并将拉伸后的PI薄膜置於一组相互交差的偏光片中观察其光学异向性，发现拉伸后的PI薄膜试片可以降低在±45o视角的漏光的效果，展现出如同A-Plate的光学补偿特性，所显现的光学补偿效果相当的均匀而且没有色偏的情形发生，证实以拉伸方法可以造成PI薄膜很均匀的双折射效应。
