Mathematics and Physics in the 19th century, another major achievement - Fourier analysis of the development of the simulator played a direct role in promoting. The late 19th century and early 20th century, have made a variety of computing the Fourier coefficients of the differential analyzer differential analysis reconciliation and so on.

As a private mobile communication system, The digital trunkingmobile communication system was boomed in 1990's, and before this, the appliedprivate mobile communication systems in market are almost the analog systemwith analog voice and digital signalling. And there are no data referring to thesystem design and parameters chosen. It includes the wireless channel accessalgorithm of the mobile terminals, single base station capacity in large regional networks, link designing schemes between the switching control center and basestation as well as the study of the service quality for the multiple traffic. Theseindispensable parameters in design a digital trunking communication system arestudied in this dissertation and some instructive achievements can be got. To provethe correction of the theoretical study, the result was tested with the popularsystem of pan-European digital trunking communication system.

数字集群移动通信系统是九十年代中、后期兴起的专用移动通信系统的一种新体制，在此之前国际、国内市场使用的都是数字信令、模拟话音集群移动通信系统其涉及领域是模拟体制，对数字集群的系统设计的有关参数、方法等的选用及其性能表现并无成熟的文献可供参考，如移动终端的无线信道接入算法、大区组网单基站系统的容量、基站和交换控制中心间的链路设计和多业务种类的服务质量等都是数字集群基站子系统进行设计和开发必须解决的关键技术。

It may have been made in the late nineteenth century as a special present for a dignitary.

它可能已在19世纪后期要人出席，作为一个特殊的。

While under natural low temperature (10-20℃), a great deal of abnormalities, including micro nucleoli, scattered and lagged chromosomes and anaphase bridges were detected during PMC meiosis, even though the abnormalities were different between the two cultivars; the ratio of micro nucleoli was 22.88% of average, which was obviously higher than that of control (4.56% of average under normal temperature); and the ratios of univalent and multivalent in diplotene, which increased seriously, were 8.82% and 17.65% of Tainong 1, and 14.52% and 24.19% of Irwin under natural low temperatures.

低温（10~20℃）条件下，减数分裂过程中核仁的行为发生大量异常，微核仁的平均检出率高达22.88%，明显高于常温条件下的平均4.56%；双线期单价体和多价体的发生频率有明显增加，其中台农1号为8.82%和17.65%，Irwin为14.52%和24.19%；减数分裂中期Ⅰ、Ⅱ及后期Ⅰ、Ⅱ均观察到落后染色体，其中台农1号异常率为12.73%、5.63%、15.79%和4.76%，Irwin为11.11%、7.61%、9.52和6.38%。

SRG-L protein wasmainly observed in diplotene/pachytene spermatocytes, round and elongating spermatids.We can conclude this gene was activated during the early stage of meiosis, andtranscription of it kept high level during spermiogenesis.

因此初步判断这个基因在减数分裂早期被激活，转录在整个精子形成期维持较高水平的表达，有可能在精子发生后期起特殊作用，与减数分裂和精子变态成形相关。

In addition, remaining strength assessment and remaining life prediction are involved in direct examination and post-assessment of the Direct Assessment process.

另外，在外腐蚀直接评价过程的直接检查和后期评价步骤中涉及到管道剩余强度评价和剩余寿命预测。

Thirdly, for the hardware based on PCI bus this paper designed the application software which is used for speech monitor. For the the hardware based on PCI-Express bus this paper design the application software which is used for interferometer direction finder.

其次，针对基于PCI接口的侦收系统的应用场合，设计了应用于语音信号监听的应用软件，并对该软件的设计做出了详细的分析；针对基于PCI-Express接口的侦收系统的应用场合，设计了应用于信号后期测向处理的应用软件。

The snail was found to have an indirect developmental type in the early development. The fertilized eggs were oval-shaped and discoidal cleavage. Embryonic development stages were divided into cleavage, blastula, gastrulae, trochophore, and intra-membrane veliger. Larval development stages included veliger, late veliger and crawling larvae metamorphosed to juvenile.

结果表明：黄口荔枝螺卵囊高度平均为7.33 mm，卵粒数量平均为165粒；黄口荔枝螺的早期发育属间接发生型，受精卵呈椭圆形，卵裂为盘状卵裂；在卵囊内，胚胎发育包括卵裂期、囊胚期、原肠胚、膜内担轮幼虫、膜内面盘幼虫；幼虫发育包括面盘幼虫、后期面盘幼虫和匍匐幼虫。

There is a relative shift in substrate utilization from CHO to fat and a better abdominal discomfortable when consumption of three days L-L meal.
