In this paper the phase shifts in spiral galaxies M 81 and M 51 has been computed. It is found that the theoretical patterns of the spiral arms agree in general with the observational results of 21 cm radio emission in the main.

本文具体计算了M81，M51两星系的恒星臂与气体臂之间的相移，给出了两星系的星臂乃气臂的式样，与21厘米射电观测结果比较表明，理论与观测基本上是符合的。

Using CHAMP observational data samples, the profiles of atmospheric bending, refractivity, pressure, and temperature were retrieved in turn by the series of signal noise ratio.

利用CHAMP卫星的GPS掩星观测资料，通过观测信噪比序列进行了大气弯曲角、大气折射率、大气压、温度剖面的反演计算；并与相位反演结果进行了比较和讨论。

In recent times, Lazio's new Argentinian striker Mauro Zarate has been compared to Beppegol, and Signori was complimentary towards the starlet.

前不久，人们总拿拉齐奥的新阿根廷射手毛罗。萨拉特和西尼奥里作比较，而西尼奥里对这名明日之星也赞赏有加。

This dissertation first introduces the hardware connection between the RS - 232 connection and the electric cable line in the numerical control workshop network communication, then it analyzes and compares syzygy type network topology and star topology based on serial port expansion card.

本文首先介绍了数控车间组网通讯中RS232C接口与电缆线的硬件连接，然后对点对点式网络拓扑结构和基于串口扩展卡的星型拓扑结构进行分析与比较，从而得出数控车间串行通信连接系统的最佳方案。

Computer-simulated results show that the introduction of acetylene bridge,which electron cloud is columned,reduced the space block between molecular functional groups.In the acetylene-bridged system,the functional groups can keep relatively free rotation,which resulted in that the conjugated electronic cloud are influenced,and then influenced on the properties of the compounds.

计算模拟结果证明，炔桥的引入降低了星状分子的核单元官能团和臂单元官能团之间的空间位阻，使得官能团可以比较自由的旋转，从而对核-臂之间的电子云共轭产生影响，继而影响到该系列化合物体系的各种性能。

In the morning during my check-out I spoke to the same mature woman about my bad experience at Antica Locanda compared to my "4 stars" expectation.

In在我与同一名成熟妇女谈话对我的坏经验在Antica Locanda与我的&4个星&期望比较的我的结算离开期间的早晨。

According to real-time requirement of stream data and losable characteristic of transportation, the thesis analysis existing stream data signature methods suc h as star-s haped tree-shaped and Golle chain. Considering the condition of limit ed resource of receiver, it proposes forward plac ed hash chain data signature sc h eme based on Gilbert-Elliot Network channel model and enhanc ed Golle chain stream data signature method.

本文针对流式数据实时性要求和传输中易丢包的特点，分析比较了现存的星型、树型、Golle链型等几种典型的流式数据签名方法，考虑到接收方资源有限的情况，基于Gilbert-Elliot网络通道模型，改进了Golle链型流式数据签名方法，提出了一种hash值前置流式数据签名方案。

Secondly, we compared four analytical models of the chemical evolution of the Galactic disk based on the new G-dwarf metallicity distribution.

其次，以我们得到的G矮星金属丰度分布函数作为观测约束，比较了四种采用星际介质化学丰度非均匀假设的解析模型。

However, no significant differences were shown between the cell cultures treated with pentavalent methylated arsenicals and control cultures in reduced rates of alamarBlue and morphological observation at the highest levels of exposure.

另一方面，暴露最高1 000 μmol/L 5价甲基砷和二甲基砷的星型胶质细胞的AlamarBlue还原力及细胞形态与对照组比较未见明显差异。

When assessing the strategy combinations in the future, the aquaculture biotechnology companies will be allowed to put emphasis on the investment of "Cash Cows", including the high quality fries and the production technology, its will bring the companies lots of profit. But the "Stars", including production equipments, the prevention and control of fish disease, the feed supplements and the environmental improvements, under industry the investment, it then will possibly take the companies toward the direction of the "Cash Cow" enterprise and gain munificent income. When the companies still have funds available, they may consider to investing in "Problem Children" enterprise, including the transgenic, the functional gene, the new variety research and the biology repair medicament. These enterprises still have the development potential, but in contrast they are operated more riskily.

三、未来水产养殖生技公司在进行策略组合评估时，可以考虑将投资重点础b金牛事业，包括优质水产种苗以及生产技术，其未来较能带给厂商业者丰富之利润；而明日之星事业包括生产设备、鱼病防治、饲料添加物以及环境改良等四项，在业者投资下，其可能往金牛事业的方向前进而带给公司丰厚之收益；当公司厂商仍有余裕资金时，可以考虑投资潜力事业包括了基因转殖、弁邬夆穧、新品种研发以及生物修补剂，这些事业仍具发展潜力，但相对也比较具有风险性。
