Glucosidase and 3-dehydrogenase of HCCB 20049-2 are induced by sugar. After studying the relationship within inducing factors、enzyme activities and transformation rate, it was found that when cellobiose was used as inducer, enzyme activities and transformation rate were both higher than other sugars.

HCCB 20049 菌中β-葡萄糖苷酶及3-脱氢酶均为糖类诱导酶，对这两种酶的诱导因子与酶活力和有效霉素的转化率的关系进行研究，发现纤维二糖诱导的β-葡萄糖苷酶和3-脱氢酶活力都较高，其valienamine 的生成率最高。

By taking advantage of a corollary of the Desargues theorem and the corresponging extension of Desarguesian configuration, the concept of stereohomology has been defined in projective geometry and presented based on homogeneous coordinates. Consequently, a series of geometrical transformations, such as central projection, parallel projection, centrosymmetry, translation transformation, reflection, rotation transformation, which can be contained in it or derived from it have also been analytically defined.

利用Desargues定理的一个推论和引申的Desargues图形，给出"空间透射"在射影几何意义下基于齐次坐标表象的解析定义，从而解析定义了可蕴涵其中的中心投影、平行投影、中心对称、平移、反射等几何变换以及可由此衍生出的旋转变换。

The results show that K-L transformation is an effective means to attenuate noise and improve signal noise ratio, and the effect of inhibition of the noise with K-L transformation is associated with the number of characteristic value.

结果表明，K-L变换可压制噪声提高信噪比，去噪的效果与所选取的特征值的个数有关。

The transformation of the cogitate style in quality is the transformation of the series of culture compositions in cogitate style.

思维方式的变化实质上就是思维方式中一系列文化构成成份的变化。

From the history of Matrix and Transformation and the development of curriculum at home and abroad, putting matrix combined with the transformation, and orienting the study in 2×2 rank matrix, boosting matrix up the geometrical visualization as a algebra objects are a new perspective on knowing matrix.

从矩阵和变换的历史发展过程和国内外矩阵和变换的课程设置来看，把矩阵与变换相结合，并定位在2×2阶上研究矩阵，增强作为代数对象的矩阵的几何直观性，是认识矩阵的一个新视角。

The other is called Householder transformation method, in which the matrix of inconsistent equation group is orthogonalized and triangulated using Householder transformation, and then the Zernike coefficients can be worked out by using a backsubstitution technique. It is proposed for the first time. Being a method that can avoid the computational error effectively and can be easily performed, it has proven to be a feasible and efficacious algorithm.

特别是第二种方法由本文第一次提出，它避免了构造法方程组，从而避免了以前的方法因构造的法方程组出现严重病态而引入的计算误差，并且易於编程，因而是一种比较理想的实现Zernike多项式拟合的算法。

In the fluvial deposit environment, the quartz superficial characteristic is primarily by the inferior circle, the conchoidal breakage fracture and the submarine hit pit, revealing the transformation of current to the quartz; In lake-deposit environment, quartz sand superficial characteristic is by primarily abraded edges and parallel cleavage, the quartz maintained the primitive characteristic, indicating the quartz received few transformation of fluent, different quartz grain has their different curve character.

在河流沉积环境，石英砂的表面特征以次圆、贝壳状断口和水下撞击坑为主，显示了水流对石英砂颗粒表面的改造；在湖泊沉积环境中，石英砂的表面特征以多棱角和平行解理面为主，石英砂颗粒保持了原始的特征，表明了石英砂颗粒受到水流的改造比较少。不同沉积环境中石英砂颗粒表面结构特征都具有自己的曲线特征。
