多因素试验遇到的最大困难是试验次数太多，造成试验成本过高。如果有5个因素对产品质量有影响，每个因素取两个不同状态进行比较，就有25=32个不同的试验条件需要进行比较。

Orthogonal subset is extracted from orthogonal geometry by collecting all traces that have a shot line and a receiver line in common, therefore the two lines are vertical bisectors. An orthogonal subset is single-fold coverage of a 3-D dataset.

在正交子集中，各种规则干扰，如面波、声波、折射以及由地面不均匀体产生的散射，在三维空间上，形成以震源或散射点为顶点的锥形体，线性噪音为从圆锥顶点辐射出的直线，具有恒定的视速度。

basing on optics orthogonal codes,this paper proposes a new design scheme of three-dimension optics orthogonal codes.in this scheme,the optics orthogonal codes can be coded not only in space-domain,in time-domain,but also in frequency-domain.it has good auto-cross relativity properties.the simulation figures show that can enlarge the coeds capacity and improve the optics optical communications system performance.so it will be of interesting in coming high dense communication system.

This method first maps training data into a high dimensional feature space through kernel function concept in Support Vector Machine and constructs orthogonal space in the feature space. Then it maps the data from feature space into the orthogonal space and computes Fisher criterion based global orthogonal discriminants.

首先应用支持向量机中核函数的概念，将样本隐式地映射到特征空间，然后构造特征空间的正交空间，再将特征空间样本映射到特征空间的正交空间，求解基于Fisher的全局正交鉴别矢量集。

Although axiomatic systems and proof method for temporal logic have found so far relatively few applications in the query language modeling of temporal database and that was proved by Gabbay, et al in 1994, the model of time axes still must be built axiomatically, which owns soundness and completeness and depicts the time axes in fine grain.

尽管在1994年，Gabbay等人论证了时态逻辑的公理化系统和证明论方法是不适合于时态数据库查询语言建模的，但是仍需要通过对时间轴的公理化建模，利用公理化系统的可靠和完全等性质对时间轴作"细精度"的语义刻画。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.
