可避免的

The mechanism of lock corridor crack is rather complicated due to the unique structure of corridor. As a result construction technique improvement cannot totally eliminate corridor crack occurrence. According to the construction process and results of Jinghang Cannel Huaiyin 3rd Lock,certain technical measures and improvements in construction techniques,can efficiently control the corridor crack and avoid the occurrence of crack as much as possible.

船闸廊道裂缝的产生机理较为复杂，由于廊道独特的结构形式，仅仅从改善施工工艺方面来完全消除廊道裂缝的出现是很难的，从本次京杭运河淮阴三线船闸工程实施过程及结果来看，通过一定的技术措施和改善施工工艺，可使廊道裂缝得到有效的控制，同时避免了有害裂缝的产生。

The main results were as follows: The stable and high efficient AFLP analysis system of peach genom...

主要研究结果如下：建立了桃的稳定可靠的AFLP分析体系：高质量的基因组DNA是AFLP分析体系的关键步骤；E+0/M+0或E+0/M+C引物组合对预扩增条带数的影响不显著；选择性扩增引物组合E+2/M+3和E+3/M+3都可用于基因组的研究，但是前者的多态性高于后者；银染显色法具有成本低、检测时间短、避免同位素污染等优点，是一种安全、快速、有效的方法。

"This little plastic and rubber self-retaining retractor enables one to do the procedure through a very small incision, without traumatizing the abdominal wall by placing metal self-retaining retractors on the rectus muscles and then pulling them apart with force," explained Dr. Glasser, noting that most postoperative abdominal pain is due to such trauma.

Glasser医师解释指出，这种由塑胶与橡胶所制成的小型牵开器，具有自动固定的功能，藉此可以经由很小的切割口来进行手术；在直肌上，藉由可自动固定的金属牵开器作撑开的动作，可以避免对腹腔壁造成伤害；而一般手术后的腹部疼痛，就是来自手术时对腹腔壁的伤害。

The model is usually an inhomogeneous system of linear equations. It is pointed out that the general solution of the homogeneous system of linear equations can satisfy the request of making the wires tight, and the special solution of the inhomogeneous system of linear equations are not smaller than zero, so their sum is greater than a given mumble.

由于多自由度绳牵引并联机构的静力学模型一般是一个非齐次线性方程组，本文指出可让对应齐次方程组的通解的最小值满足绳保持张紧的条件；让非齐次线性方程组的特解非负，而避免利用对应齐次线性方程组的通解保证非齐次线性方程组的解不小于给定的最小值。

E. Construction of optional transhipment station's set provides a practical interface for man_mechine interaction in model computation, and an effective method to prevent some absurd cases, such as: uptrains trasship in down yard, or down trains tranship in up yard.

e。可选中转站集合的设立，为模型计算过程中的人机交互提供了一个接口，也为避免上行车流选择下行编组线、或下行车流选择上行编组线进行改编中转的不合理的情形，提供了一行之有效的解决办法。

Because protein synthesis costs energy while protein canalso be used as a source of available energy,there is an interaction during growthbetween the utilization of dietary protein-free energy and protein.

在自由采食量的预测方面，提出了用累计采食能量对时间进行多项式拟合的方法。该方法可以避免预测自由采食量时的系统偏差，并可应用到对模型的调试和验证中去。

The orientation-singularity expression of the Stewart platform is deduced by using unit quaternion which can avoid singularity when using Euler angles to represent the orientation of rigid body, and then the algorithm of orientation-workspace of the manipulator at a certain position is proposed.

基于单位四元数描述的刚体姿态，避免了欧拉角等描述刚体姿态的奇异性问题，推导出Stewart机构处于给定位置时的姿态奇异解析表达式，并提出了该机构处于给定位置时的姿态工作空间算法，通过计算机仿真给出该机构处于一给定位置时姿态奇异轨迹和姿态工作空间的三维可视化描述。

The point contact condition can not only avoid the tooth edge contact, decreases the kinematical errors and vibro-acoustic due to axial misalignments, but also increases the bearing strength of the contact gears.

点接触的接触型态不仅能使齿轮组避免齿缘的接触及降低由轴向组装误差所引起的运动误差和振动噪音，更可增强齿轮的接触强度。

LabVIEW 7.0 Express-based program for determining second-order reaction rate constant by electric conductivity is designed.
