可表达的

Symbol with a special meaning can be matched, but to do so it must be prefixed with the backslash character (this includes the backslash character itself: to match one backslash in the target, the regular expression should include '\\').

数字符有特殊的含义，以经常性的表述。A符号与a特殊的意义可匹配，但这样做必须前缀的反斜杠字符(this包括反斜杠字符本身：匹配一个反斜杠的目标，应该经常表达包括'\\')。

Furthermore, we find the way to handle several important problems which couldn't be solved previously, with the help of the method of multi-objective decision-making, the method of simplification of the model, the method of experiment designing and the calculating method of inference believability etc.

本文的主要贡献可概括为以下几个方面：第一，在因素空间中，利用所定义的带有模糊命题时序关系描述的模糊推理网，提出了工业系统知识的一种表达方式，弥补了现有模糊模型不便于描述动态系统知识的缺陷。

Results Primary RPCs extracted from the neural retina demonstrate certain biological characteristics: the cell population could form neurospheres and younger adherent cells expanded in clusters.

结果 从兔胚胎视网膜神经部分离出的原代视网膜前体细胞具有明显的生物学特性：所培养细胞可形成悬浮生长的细胞团，刚贴壁的细胞成簇状生长，这些细胞用免疫细胞化学染色神经上皮干细胞蛋白表达呈阳性。

Institute of Statistics and Actuary, Shandong Economic UniversityAbstract We consider the risk process perturbed by diffusion under interest force in this article. The integral expressions, continuities, twice continuous differentiability and integro-differential equations about $F_{\delta}$, the distribution of the surplus immediately before ruin, and $H_{\delta}$, the joint distribution of the surplus immediately before ruin and the deficit at ruin are obtained.

我们考虑既带有随机干扰又带有确定投资回报的风险过程，得到了破产前瞬间盈余的分布$F_{\delta}$及破产前瞬间盈余和破产时赤字的联合分布$H_{\delta}$所满足的积分表达，连续性及二次连续可微性和积分--微分方程。

Due to the deficiency of cyclin B1 and 〓, spermatogonia and pachytene/diplotene primary spermatocytes in contralateral cryptorchid testis were unable to form MPF, and therefore, they could not accomplish their nuclear division, and became arrested at the transition stage from mitosis to meiosis (G2/M phase). We also found that testosterone could regulate the cyclin B1 expression in spermatogenic cells.

由于cyclin B1和〓的缺失，粗线期/双线期初级精母细胞中的MPF无望形成，从而导致生精细胞分裂停滞在由有丝分裂向减数分裂过渡的G2/M相；（5）睾酮可在翻译水平上调控阴囊内睾丸生精细胞cyclin B1蛋白的表达。

Endothelial Ang-2 expression is associated with essel destabilization and regulates a balance between ascular regression and growth.

血管内皮的Ang-2 的表达与脉管的不稳定性有关，其可调节血管的退化与生长之间的平衡。

Jing is a fundamental structure of Qihua which can't express any defference of future life at stage of Jing; Yin Yang expresses the evolution regularity of life which has defferent nature; five elements expresses a team of natural number which under five elements and it contral life to evolute at five stages.

生殖之精，是生命基本的化演单位，气化之宇。阴阳，表达生殖之精依靠气化，演化出的具有某些相对的可比较属性。五行，是反映生命体在气化作用下，同源演化区域里生命结构或功能渐变的五大变化序态。

RESULTS: hMSC had good homogeneousness and immunological reaction after implantation.

结果： 第5代呈集落生长的hMSC，均一性好。hMSC可在脑内存活6周以上；随着时间的延长，hMSC在脑内迁移的范围越来越大；间接免疫荧光表明hMSC在大鼠脑内表达人神经元特异性烯醇化酶、神经丝蛋白和胶质纤维酸性蛋白；模型鼠的肢体运动功能有明显改善。

Voltage-gated Na+ channel 1.8 contributes to the majority of the Na+ current that underlies the depolarizing phase of action potentials. Nav1.8 is mainly distributed intracellularly and its current amplitude can be enhanced by the β3 subunit.

电压门控钠离子通道是可兴奋细胞产生动作电位的基础，Nav1.8是特异性高表达在背根神经节初级感觉小神经元中的一种电压门控钠离子通道，它与疼痛的产生有密切的关系。

The building is set in a spiraling pattern of two small meadows and a pond that have as much to do with defensive fortification as with pastoral serenity: an eye-opening expression of the irresolvable tensions involved in trying to design an emblem of American values when you know it may become the next terrorist target.

新使馆周遭有呈螺旋状的两个小草坪和一个水潭，除了可当防御工事，也可以强调田园的宁静：在试图设计一个代表美国价值观的地标时，明知它可能成为下一个恐怖攻击目标，这栋建筑表达了其中无法解决的紧张冲突，令人大开眼界。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
