Methods Cell viability of the stented homograft valve preserved in liquid nitrogen after 3 months of preservation （experimental group,n = 6） was examined using flow cytometer.

制作同种带支架瓣膜经液氮保存3个月后，利用流式细胞仪技术定量检测瓣叶细胞活性（实验组，n=6），采集新鲜同种瓣膜作为对照（对照组，n=6）。

The differentiation coefficient is 0.07 between three inbreed families respectively. The highest level of genetic homozygosity is in families Ⅱ at 18, but genetic variation is a little difference between inbreeding pig and mice. However, this study revealed the pattern of genetic variation at microsatellite loci in the 3 inbred families of WZSP with one of the most important findings to be the high level of unexpected heterozygosity at some loci, e.g. Sw874 and Sw936 that could be part of the unique genetics of three families. A hypothesis is that certain functional genes linked with such microsatellite loci may be involved in the maintenance of viability of these inbred families of WZSP remains for further investigation.

随近交代数的推进，每个星座上等位基因数越来越少，基因的纯合度越来越高，但WZSP近交系微卫星等位基因的纯合度有一定的限度，与近交鼠有所不同；在近交系3个家系各个世代中有少数几个基因座，如Sw874和Sw936等一直处于高度杂合状态，这可能与WZSP近交家系的种质特异性有关，推测与这些基因座处于同一连锁群的某些功能基因在维持极高近交水平下WZSP的基本生存能力中起着关键作用。3个近交群体间的分化系数在0.07以上，已各自成为独立家系；3个家系的近交程度不完全一致，基因的纯合度亦不同，Ⅱ系最高、14个微卫星座中7个纯合，其次为Ⅰ系和Ⅲ系。

The results were as follows:The embryo-bud length, embryo-shoot length, embryo-shoot number and dry weight of embryo-shoot of maize inbreed line decreased evidently under osmotic stress within germinating period. So the germination date was delayed, the germination rate and viability decreased.

研究结果如下：在萌发期渗透水分胁迫条件下，玉米的胚芽长、胚根长、胚根条数、胚根干重等均有明显的下降，因而发芽时间延迟，发芽率下降。

The whole state space is divided into invariant subspace, safe subspace, dangerous subspace and dead subspace according to the constraints and the safe margin of the system, and the state reference trajectory is chosen with respect to the subspace in which the state prediction lies in, in this way GPC is applied under the prerequisite for the viability of the system.

研究了系统在线性不等式约束条件下的预测控制问题，将广义预测控制算法化为对控制量的一步优化，根据约束条件和输出预测在线修改控制量的加权系数，提出了一种变加权系数的改进算法，使系统始终满足给定的约束条件。

Along with our country letter loan property the stock certificate turn a formal start of make experiements the project, domestic already research the focus turn viability assessment argument from the first property stock certificate, the stage quickly transfers to establish with operation mode of actual usage stage of study up.

随着我国信贷资产证券化试点方案的正式启动，国内已把研究焦点从最初的资产证券化可行性分析论证阶段迅速转移到设立和操作模式的实际运用阶段的探讨上。

However, it's clear that if levelheaded economic experts are even pondering the viability of Europe's monetary union, the situation is grave indeed.

不过，如果连稳健型经济专家都开始怀疑欧洲货币联盟的生存能力，问题显然已经相当的严重了。

Therefore, the difference between the low-class stage and the advanced stage of the human society is determined by the human survival consciousness and viability.

因此，人类社会的低级阶段与高级阶段的区别，就是以人类的生存意识和生存能力来进行判断，人类的生存意识和生存能力体现为人类的创造能力，创造能力越强，社会就越高级，创造能力越弱，社会就越低级。

However, the membrane of blood cells is damaged and viability of blood cells is decressed in lyophilization.

然而，在冻干过程中血细胞膜的损伤、细胞功能的降低是一个重要的问题。
