The maps are not,however,desirable and entire because all of the markers on the maps come from the no recurrent parent.The consequence is that number of the markers used for map in backcross population is never more than half in intercross population.

但是，用回交群体作图所得的图谱是不完整的，因为图谱上所有的标记都是非轮回亲本提供的，因此标记数不会超过杂交F2群体的一半。

2According to requirement of suppressing stray light in two-mirror system, vertex coordinate formulas of inner baffle are deduced based on geometrograph in the case of certain obscuration, viewing field and vignetting. In order to reduce the obscuration, conical baffle of secondary mirror is ameliorated into a shutter one. Outer baffle is designed when angle of stray light suppressing is foregone and the vanes are designed in C-language program. Finally, the same-height vanes in drawtube between primary and secondary mirrors are designed for further suppressing the stray light in two-mirror system.

给出双反射系统杂散光消除设计的具体要求，结合作图法，推导出考虑视场大小及初始中心遮光比确定时，主次镜内遮光罩顶点坐标公式；讨论考虑渐晕时主次镜内遮光罩的设计；为了减小初始中心遮光比，将次镜锥状遮光罩改进为百叶窗式结构；设计在杂散光源抑制角已知时的外遮光罩，并利用C语言实现程序化设计其挡光环的方法；设计主、次镜间镜筒内壁上等高挡光环，进一步抑制双反射系统的杂散光。

The basic principle is based on spherical astronomy and elementary geometry of the trajectory mapping method based on the observation of a celestial body zenith distance, then the ship is located in order to sing the next point as the center of this satellite zenith distance of the ship's position as the radius of the circle, observing the same two objects, or objects at different times of the two observations, we can get two ship's position round, then the ship must have been a point of intersection of two ship's position on the circle.

其基本原理是建立在球面天文学和初等几何中的轨迹作图法基础上的，观测一个天体的天顶距，则航船就位于以星下点为圆心，此星天顶距为半径的船位圆上，观测两个天体或者不同时间同一天体的两个观测值，就可以得到两个船位圆，则航船一定在两个船位圆的一个交点上。

Graph coloring is a highly e?ective approach to globalregister allocation. In this paper, we should study priority-based register allocation, whichis a e?

常用的寄存器分配算法是被称作图染色的寄存器分配算法，本文所研究的基于优先级的寄存器分配就是图染色算法的一种。

Methods Spectrophotometry was used to study the activity of PLAP in the presence and absence of L Leu. PLAP relative activity was calculated according to the absorbance variation.

方法应用分光光度法分别测定有L－Leu和无L－Leu存在下的酶活力，根据其活力变化求出酶的相对活力；用双倒数作图法，确定L－Leu对PLAP的抑制类型并求出其抑制常数；同时也观察了pH对抑制作用的影响。

The new statistical analysis methods are mostly based on mixed linear model approaches for estimating variances and covariances, unbiasedly predicting random effects, analyzing conditional variaces and effets, and composite interval mapping.

基于混合线性模型的分析原理的统计分析方法包括方差和协方差估算方法、随机效应的无偏预测方法、条件遗传方差和条件遗传效应的分析方法、复合区间作图方法等。

It is also essential that graphic data can be annotated in a way which is recognized by analysis programs but which does not affect the draughting system.

另外， 另外，图形数据可用能被分析程序识别但不对作图系统产生影响的方法进行注释。定语从句中两个which的功能一样，都的功能一样，定语从句中两个的功能一样用于修饰in 用于修饰

Acterial artificial chromosome has several notable advantages, such as inserting large fragments, maintaining the stability of inserted DNA in E.coli, producing few chrisms, recovering inserted DNA from E.coli cell and easy in library construction.

AC文库的构建是基因组较大的真核生物基因组学研究的重要基础，可用于真核生物重要基因及全基因组物理作图、重要性状基因的图位克隆、基因结构及功能分析。

Methods Firstly, the conductivity of DyCl3 in isopropanol was determined at 303.15 K to 313.15 K to calculate the molar conductivity of DyCl3 secondly, Kohlrausch formula and Origin software were used to make the diagram of linear fitting, finally the diagram was pushed outside and the molar conductivity at infinite dilution λ0/(Scm^2mol^(-1) of DyCl3 in isopropanol was calculated, and the influence of the temperature on λ0/Scm^2mol^(-1 of DyCl3 electrolyte solution was investigated.

根据实验在303.15~313.15K温度范围内测定DyCl3在异丙醇溶剂中的电导率，求得DyCl3的摩尔电导率值，应用Kohl-rausch经验规则，使用Origin软件进行线性拟合，作图外推求得DyCl3在异丙醇中的无限稀释摩尔电导率λ0/S平方公分mol^(-1值，并讨论DyCl3在异丙醇中的λ0/S平方公分mol^

A software for QTL mapping—QTLMapper 2. 0 written by C/C++ language was developed. The sotftware could analyze populations of DH, RIL, F〓 and permanent F〓, and could provide unbiased estimation for all genetic main effects and/or unbiased prediction for all QE interaction effects. The software could also predict heteroses of single-cross offspring based on QTL genetic main effects and/or QE interaction effects obtained in QTL analysis of F〓 or permanent F〓 population.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
