In designing process, it will waste time on determining parting directions. For this reason, we generate a method for checking partibility by using the relations of the normal vectors of shapes. If the mold was decided as partible object, the process would evaluating the range of the parting directions. Also, the result of parting directions will be demostrated by one cone named parting cone. The total procedures of determining partibililty require O time.
基於这样的原因,本文提出一个判断可脱模性的方法,利用自由曲面上三角化之后所得到的法向量的分布情形,进行运算,若判断为可脱模模型,并计算出可脱模模型的脱模范围,使用圆锥表示之,此圆锥既称为脱模角,过程所需的时间复杂度为O;若判断为不可脱模模型则所需要的时间复杂度为O。

For example, it is a pathogenic bacterium and has endotoxins; it secretes protein into the periplasm and often into inclusion bodies. Bacillus subtilis is an attractive host for the production of heterologous secretory proteins. Many genes has succeed expressed in Bacillus subtilis, and the plasmid vectors for Bacillus subtilis are now taken from other genus bacterium, such as Staphylococcus aureus or lactococcus lactis and so on. As it is clear to known that these plasmids are far from optimal for Bacillus subtilis, because of low efficiencies of cloning and high levels of replicating instability.
枯草芽胞杆菌是目前原核表达系统中分泌表达外源蛋白较理想的宿主,近几年已在枯草芽胞杆菌中成功表达了多种基因,但大多都应用来源于金黄色葡萄球菌、乳酸杆菌等的载体来表达外源基因,由于其在枯草芽胞杆菌中存在分离复制的不稳定及外源基因的克隆表达效率低的现象,故都不是枯草芽胞杆菌的最佳选择,还有待改进。

YAC is now prevailingly used as the first cloning vector for human genome analysis, but one problem that is not yet solved is the insert DNA fragment is not easily isolated from yeast chromosomes and vectors. So, we developed a new technique for the specific radioactive labelling of YAC insert by Alu-PCR technique.
因目前YAC中的插入片段还无法分离出来,因此我们对筛选到的这些YAC,用Alu-PCR技术将人基因组插入片段进行了特异扩增,并通过PCR条件的适当改变,获得较理想的标记效果。

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。
