由于对称阀控制非对称缸两个运动方向上系统的开环增益及某些参数的不同，使得两个方向上的动态特性不对称，主要表现在超调量、调节时间、振荡次数和稳态误差等几个方面，这种本质上的非线性和非对称性给系统控制带来困难。

The owners and the executives of a business are principals and agents. Therefore, there are so called "agency problems" between them, such as "different objectives and interests","disproportional control of information", and "disproportional responsibilities and risks".

企业的所有者和企业的经营者之间的关系，是委托人和代理人的关系，这样，在两者之间就存在"目标利益不一致"，"信息控制不对称"，"责任风险不对称"的所谓的"代理问题"。

Einstein only has dispelled the unsymmetry of the explanation for electromagnetic interaction, but can't dispel the unsymmetry in size of electromagnetic interaction.

爱因斯坦只是消除了电磁相互作用的理论解释的不对称，他那个方法不能消除电磁相互作用的大小的不对称。

Under the direct current electric field, the expression of PDGFR were increased obviously and distributed asymmetricly on the membrane of VSMC. This receptor were mainly focused on the cathodal side of cellular membrane in electric field. The AT1R were also enhanced in the cells after exposure to the electric field, and the expression of AT2R had showed the changeless.

改进的电场干预装置作用下，血管平滑肌细胞膜血小板源生长因子受体表达增加，部分细胞内血小板源生长因子受体表达上调，呈不对称分布，在电场负极面较集中；细胞中血管紧张素Ⅱ1型受体表达亦增加，但无明显不对称分布现象；血管紧张素Ⅱ2型受体表达改变不显著。

We also studied the enantioselective conjugate addition of chalcone in the presents of chiral Ni2 aminoalcohol complexes.

我们还研究了手性氨基醇配体/镍盐催化的a，β-不饱和酮的不对称迈克尔加成反应，以及酰腙的不对称烯丙基化反应。

For certain reactions, they function as chemoenzymes and produce both good chemical and optical yields. Over the last decade a wide range of C〓-symmetric chiral bisoxazoline ligands have been synthesized from readily available diacid derivatives and amino alcohols.

但是，手性双噁唑啉催化的某些不对称反应的机理以及影响双噁唑啉分子催化性能的结构要素目前仍不是很清楚，诱导某些反应的不对称选择性仍有待于进一步提高，因此需设计和合成新的双噁唑啉类配体。

Considerable attention has really been focused on ionic liquids as "green" alternatives to classical environmentally damaging organic solvents in many fields such as in organosynthesis, material, catalysis, electrochemistry, biochemistry, physicochemistry, separation and so on. However, there have been only a few examples of chiral ILs have been reported so far, and ILs possessing chirality are having been synthesized aimed at application in asymmetric catalytic reaction.

离子液体在许多领域如电化学、有机合成、催化、生物化学、物理化学、材料及分离等的绿色替代溶剂技术引起了人们的重视，然而，有关手性离子液体的合成与应用的报道比较少，含有手性片段的离子液体不断被合成出来并期望在不对称催化反应中得到应用，但是成功的例子不多，使用手性离子液体在不对称催化反应中还在初始的探索阶段。

The unusual quality of one tie up of the space-energy make the gravitation of quantum spatial measurement cosmic energy, lave the absolute point of unusual quality one tie up of in cosmic time-space, come to do not symmetrically gradually belong to stabilization thus at reductively fluctuate, not can reversely strides across reach the stable state of limitedly relatively not symmetry, come to do the circle of shut locus thus infinite continuous stable strides across.
