几乎与此同时，实验还发现在单极化强子-强子反应中产生的末态强子存在方位角不对称，被称作单自旋左右不对称。

It is rather limited for market economy to merely depend on the market to solve the problems in the unsymmetry of price information.

在市场经济中仅仅依靠市场来解决价格信息不对称问题是有局限性的，而只有依靠市场、政府、第三方力量等综合手段才能解决价格信息不对称问题。

Flowers bisexual, actinomorphic or zygomorphic, usually subtended by 1 to several spathaceous involucres.

花两性，辐射对称或者左右对称，通常被1到几个佛焰苞的总苞包着。

In order to improve the luminescence and thermal performance of asymmetric ROPPVs, a series of poly derivatives with asymmetric alkoxyl substituents/ nanometer semiconductor composites were synthesized through dehydrochlorination in-situ polymerization.

为了进一步改善不对称ROPPVs的发光性能和热性能，首次采用原位脱氯化氢缩合聚合法，合成出一系列不对称烷氧基取代聚对(来源：9bab9bABC论文网www.abclunwen.com)苯乙炔衍生物／纳米半导体复合材料。

There is competition between the symmetrical and antisymmetrical modes, under certain conditions, one mode may prevail, producing synchronization of the near wake flow.

对称和反对称模式存在竞争现象，在确定的条件下，某一种模式占据主导地位。

Place when three-phase loads are not balanceable on the running occasion of motor energy-saving, which canattaint appliances.

应用中，由于负载的不对称，容易产生三相不对称交流电压，甚至是直流电压，严重时会损坏电气设备。

Least-squares solution for the inverse problem of real matrices、symmetric matrices and bisymmetric matrices are studied in this thesis. The thesis includes the following contents.

本文研究了子阵约束下实矩阵、实对称矩阵和双对称矩阵反问题的最小二乘解，全文主要包括以下内容。

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。

The first asymmetric synthesis of trans-β-hydroxy-γ-butyrolactones:-(3R, 4R, 5S)-4-(1-acetoxy-isopropyl)-3-hydroxy-butyrolactone 65a was achieved starting from isobutylaldehyde through nine steps. The key steps involve the construction of three chiral carbon centers by the Sharpless's asymmetric epoxidation and Substrate directable chemical reaction.

Based on different structure types, the slide shoes are designed in symmetrical and dissymmetrical, continuous and discontinuous types, therefore, the loading technique is characterized by diffcult operation, high technical requirements and complex process.

由于结构物类型不同，滑靴的设计有对称与不对称、连续与不连续之分，因此滑移装船作业难度大，技术要求高，工艺复杂。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
