常数项

Compared with Mg2+,the physiological cofactor,Mn2+has a slight activation effect on GTP-hydrolysis activity.The kobs of the exponential phase of the experiment curve of Mn2+is two-times higher than that of Mg2+under saturated condition.And the velocity of the steady state is lower than that of Mg2+.

相对于生理条件下的辅基Mg2+而言，Mn2+对Cdc42Hs酶活力有所激活，表现在饱和浓度时，实验曲线指数项的表观速率常数kobs有2倍左右的提高，而其稳态反应速度要低于Mg2+。

A multi-distance measurements method is employed in this paper. A single parameter fitting method and a double parameters (reduced scattering coefficient and amplitude factor) fitting method on the basis of the least square Newton fitting algorithm is used to derive the optical parameters respectively. For the finite-thickness homogenous tissue, it can be concluded that the rest terms in expressions of diffusion reflectance and transmittance for the corresponding tissue geometries that subtract the exponential term contained source-detector distance depend on the detected position weakly.

在多程测量的基础上，使用单参数最小二乘牛顿法拟合方法和双参数（约化散射系数、幅度因子）最小二乘牛顿法拟合方法，得到有限厚均匀组织的反射率分布和透射率分布公式中除去包含测量位置的指数项的其它部分对测量位置皆具有弱依赖性的结论，并对拟合结果进行了分析讨论；而对于有限厚平板状双层组织，可根据对反射测量结果及透射测量结果进行拟合所得的约化散射系数间的差异及常数因子的正负判断双层组织的可能结构分布。

The data acquisition system simulated the function of data acquisition that ship model tank did. The simulation test system estimated the real-ship resistance, ship resistance estimation is an important content to determine its speed, and analyze the quality during the early stage. This simulation system mainly estimated the ship resistance with Ayre method and navy constant method, then compare the result with ship model test.

其中，数据采集系统模拟船模试验水池数据采集功能而进行模拟仿真，模拟试验系统主要进行实船船舶阻力估算模拟，船舶阻力估算是船舶方案设计初期的一项重要内容，以确定船的航速，便于初步分析比较各种方案的优劣，系统主要针对船舶总阻力估算方法中常用的爱尔法和海军常数法进行模拟仿真。

According to the basic equations derived under the two assumptions by Harold Lauffer—(1) the energy head of every point of a vertical section remains constant,(2) the flow lines are concentric circular arcs,this paper qives a comprehensive deduction of curvature effect in the characteristics of free overflow of round-crested spillway.118 runs of experiments of three round-crested spillway models of different size have been conducted by the author.

本文根据劳弗尔氏在两项假定[(1)垂直测线上各点所含能量为常数，(2)流线呈同心圆弧]下所导得的基本公式，作了详细的补充引伸，得出圆顶壩自由溢流时各项水力特性中的曲率影响计算公式。作者曾进行了大、中、小三个圆顶壩模型的试验共118组，试验成果基本上和导得的计算公式相合致。文中并根据试验资料制定了一些经验公式，应用时可更简便。
