I took the young Irish setter for a walk up the road and along the frozen creek, but it was difficult to stand or walk on the glassy surface and the red dog slipped and slithered and I fell twice, hard, once dropping my gun and having it slide away over the ice.

我带着我的那条爱尔兰猎犬，沿着大路和一条冰冻的小溪散步，但在这玻璃般平滑的地面上站立和行走是很困难的。红毛狗一路上连跌带滑，我自己也摔倒了两次，都是挺重的。一次猎枪也甩了出去，在冰上滑出去老远。

Since the linear systems involving Kronecker product and multiple right-hands are widely applied in many areas, we shall investigate the condition numbers for these linear systems: In chapter 1 we briefly review the background of linear systems and numerical algorithms for solving them. We also introduce the source of condition numbers.

由于带Kronecker积和带多右端项的线性方程组在很多领域得到了广泛的应用，因此本文对这类方程组的条件数进行了研究：在第一章中我们简单回顾了线性方程组问题的研究背景和数值求解方法，并介绍了条件数问题的来源。

Though low-speed streaks occur randomly in time and space, the streak spacing exhibits a lognormal probability distribution.

低速条带的合并和猝发，是导致条带数量减少，〓随y〓增大的重要原因。

The results of isozyme analysis show that the number of isozyme bands of peroxidase, cytochrome oxidase and superoxide dismutase are 13, 11 and 10, respectively. But that of amylase, esterase and malate dehydrogenase are only 4, 7 and 7, respectively.

结果表明：过氧化物酶、细胞色素氧化酶、超氧化物歧化酶等三种酶的同工酶酶谱很丰富，分别有13、11、10条酶带；淀粉酶、酯酶、苹果酸脱氢酶等三种酶的同工酶酶带相对较少，分别为4、7、7条。

The FMI image of alga limestone reservoir features in floe or cloud-like, oilier boundary being not straight, asymmetry internal structure, disorder bedding, local dissolution; The FMI image of siltstone reservoir and calcareous siltstone features in bright-yellow, brown-yellow strip: and The FMI image of limestone and marlite feautures in white, bright-yellow and white black interbedded strips.

藻灰岩储层FMI图像呈絮状或云朵状，外部边界不平直，内部构造不均匀，层理无规律，局部有溶蚀现象；泥质粉砂岩与钙质粉砂岩的FMI图像为亮黄色、棕黄色条带；而石灰岩、泥灰岩为白色，亮黄色及黑白相间的条带。

A band of 850 bp was generated in the line of non-parthenocarpy by the primer N92 both in the parent and in the DNA pool. Accordingly, it is possible that the primer N92 might be used to phenotyping the trait of cucumber parthenocarpy, and further we calculated the genetic distance between the marker and cucumber parthenocarpy trait that might be 18.9 cM.

用65条ISSR引物进行PCR扩增筛选，其中引物N92在亲本和DNA池之间扩增出一条大小为850bp多态性片段，经F2代群体135个单株验证，该片段稳定出现，在单性结实植株中表现为无带，在非单性结实植株中表现为有带，可以作为鉴别单性结实与非单性结实的标记引物。

The changes of nutrition in milk treated with different technologies are also determined. Results showed that, 1 higher pressure, longer holding time and more alternative times favour a larger destruction of microorganisms; 2 the combined effect of hurdle technology and pressure on the destruction of microorganisms in fresh raw milk is more effective than only using pressure treatment, among which the effect of ε-polylysine on inactivation of microorganism in fresh raw milk is more effective than that of Nisin with the same concentration of 100mg/L; 3 the whole proteins in milk treated by the different types of sterilization have been detected by SDS-PAGE electrophoresis, and comparing with the whole proteins' electrophoretogram of fresh raw milk, we found that the first spectrum band near the negative pole was disappeared and the colours of the second spectrum band was tint in UHT, pasteurism and 500MPa treated milks, which was suggested that some proteins' subunits were dissociated, but the 400MPa treated milk showed the similar eletrophoretogram with the fresh raw milk; 4 the loss of threonine, VA and VC in high pressure treated milk was more less than those in pasteurism treated milk, in particular threonine and VA were almost retained, and the contents of VB1 and VB2 in the former are also more than that in the latter; 5 high pressure treated milk had longer shelf life than pasteurism treated milk, extending the sale semidiameter of milk.

压力越高，保压时间越长，交变次数越多，杀菌效果越好；2）采用栅栏技术对牛乳中的微生物具有更有效的杀菌作用，其中相同浓度的（终浓度100mg/L）ε-聚赖氨酸较Nisin具有更强的杀菌效果；3）利用SDS-PAGE电泳研究了不同杀菌方式对牛乳总蛋白的影响，发现经UHT、巴氏和500MPa交变处理的牛乳与生鲜牛乳相比其总蛋白电泳图谱靠近负极方向第一条谱带消失，第二条谱带颜色变浅，由此推测经上述处理后牛乳中有一些蛋白质的亚基发生了解离，而经400MPa交变处理的牛乳与生鲜牛乳的总蛋白电泳图谱相似；4）超高压牛乳营养成分与生鲜牛乳相比，苏氨酸、VA、VC在超高压处理中受到的破坏明显比巴氏杀菌小得多，特别是苏氨酸和VA几乎完全被保留下来，而VC含量也要比巴氏奶高出25%以上，对于VB1、VB2，检测数据也表明，超高压灭菌对其破坏要比巴氏灭菌小，其含量分别比巴氏杀菌牛乳高出9.5%和2.6%；5）与巴氏杀菌乳相比，超高压杀菌有助于延长牛乳的保质期，扩大牛乳的销售半径。
