查询词典 sampling fraction

What fraction of alanine is in the completely uncharged form at its pI?

在等电点pH时，有多大比例的丙氨酸是完全不解离的？

We proposed a new method by improving it in a novel way, which can generate pixel of a line row by row according to the first and second row of a line and inherit the advantages of Bresenham algorithm without division and decimal fraction.

该算法在保持Bresenham算法不使用取整和小数运算的优点下，还提高了直线生成效率，一次计算可以生成一个像素行。

While calculating tensor Green's functions, the algorithm of secondary division is adopted to solve the singular problem. The Gaussian quadrature and continued fraction is adopted to calculate the integral with Bessel function. This method not only can ensure the right calculation of tensor Green's functions but also can get high precision.

求取张量格林函数积分时，采用二次剖分算法解决计算中奇异值问题，对于含有贝塞尔函数的积分项，利用结合连分式展开的高斯求积代替常规的快速汉克尔变换方法，确保了张量格林函数的正确计算并提高了计算精度。

The track structure of low electron, proton and alpha particle in water as a media has been calculated with Monte Carlo method. The spectrum of DNA damages has been simulated by the track structure model. Then the surviving fraction at different dose level is calculated by connecting track structure and phenomenological dynamic model.

在理论方面，对电子、质子和α粒子在水中的径迹结构进行了系统地研究与计算，还编制了我们自己的质子的蒙特卡罗模拟程序；用径迹结构模型计算出电离谱并与动力学模型相联系，计算出有实用价值的成活率。

By analyzing the molar fraction of St and MAh in the copolymers obtained from 〓C spectra, the copolymers obtained are proved to be strictly alternating structure, and sequence information obtained from DEPT experiments also verifies the copolymers with MSM sequence.

通过分析〓C NMR得到共聚物中St和MAh摩尔含量，证明共聚物具有严格交替结构，从DEPT实验中得到的结构信息表明共聚物只含有MSM序列。并且探讨了可控聚合反应的机理。

An unexpectedly large fraction of players acted altruistically to protect their weaker friends.

远远超出人们的预料，有很大一部分玩家在游戏中无私地保护那些弱者朋友。

One surprise was that players put themselves into risky situations more often than epidemiologists allow for in their models. An unexpectedly large fraction of players acted altruistically to protect their weaker friends. On the other hand, a significant number seemed intent on infecting as many other characters as possible—behaviour reminiscent of a small minority of people with AIDS.

一个惊奇的发现是，玩家比流行病学家的模型更易于将自身置于危险境地，在保护弱者朋友时表现出利他行为的玩家异乎寻常的多，另一方面，有相当数量的玩家似乎在尽心竭力地感染尽可能多的其它游戏人物——这使我们联想到少量艾滋病人的行为。

Especially aiming at the asymmetric structure of the cast, the allocation of aluminous liquid during the filling process was presented and the concept of structure mass fraction was inducted.

针对铸件的不对称结构提出了充型过程中铝液的分配问题，引入结构质量分数的概念。

Compared to Ambler , they are cheaper to launch into space by a factor of 1000; thus, sending hundreds of mobots is a fraction of the cost of one large robot.

和 Ambler 相比，他们的发射到太空的费用便宜1000倍；这样一来，即便发射数百个的成本也只是一个大机器人的很小一部分。

This paper studied the antioxidation of polysaccharide fraction AGP-3 from Ampelopsis Grossedentata in vitro.

研究了藤茶多糖组分AGP-3的体外抗氧化活性。

"Second Life is remarkably easy to work with, and is very popular,"

"第二次生命是显着容易的工作，并且很受欢迎，"

For example, we usually assume that materials are homogeneous and isotropic and free of internal defects or flaws.

为了得到适合有限元分析的模型，我们必须经过如图2所示的简化步骤。
