可逆的

At last,based on the traditional cluster-cluster aggregation model we introduce acritical cluster size and a breakup exponent that depends on the fragment sizes in thereversible and irreversible cluster-cluster aggregation processes.

在第六和第七章中，我们研究了临界集团的大小对可逆和不可逆集团聚集过程标度行为的影响。我们知道，在一般的CCA模型中，只要二个集团通过扩散碰到一起，它们便融合成一个更大的集团。

The cycle test results show that the introduction of trace anisole can promote specific capacity and cycling efficiency and can reduce the declining rate of the specific capacity.

以Li金属和改性石墨为电极材料，循环性能测试结果表明，苯甲醚的加入，使电池的可逆比容量和充放电效率均得到提高，且可逆比容量的衰减速度减慢。

This study demonstrated that KA administration in a convulsant dose could result in spontaneous recurrent seizures and permanent disturbances of behavior and cognition in old rats (P25、P60) which brains were in mature. However temporal and reversible effects occurred in rat pups (P5、P15) in immature brain.

一次给予惊厥剂量的KA可诱发脑发育成熟大鼠（P25、P60）出现自发癫痫发作，但在脑发育未成熟大鼠（P5、P15）中未见有自发癫痫发作；KA致痫对脑发育成熟大鼠造成的认知行为异常持久而不可逆，但对脑发育未成熟幼鼠认知行为的影响则持续时间短而可逆。

In this paper,a novel wire feeding system composed of special motor driver circuit with high frequency and print motor with low inertia was designed,and the performance test were carried out.

采用特制的高频可逆调速电机驱动电路配合低惯量的印刷电机，研制了一种适用于GMAW焊接电源的新型可逆调速送丝系统。

This paper introduces the principle of electromotor based on single chip computer 8051PWM,and the realization process of reversible control and non- reversible control .

介绍了基于单片机8051PWM控制的电动机原理，阐述了8051与直流电动机构成的电机可逆控制和不可逆控制的实现过程。

The experimental results from cyclic voltammetry and constant-potential electrolysis show that the mechanism of the reaction was two molecules and three steps electrochemical process with eight-electrons transferred: anion radical arose in the first step; two-electrons were transferred in the second step and accompanied with coupling reaction of radicals and protonation and dehydrate, the main product was azoxybenzene; two-electrons were transferred in the third step, and azobenzene was achieved.

研究结果表明，硝基苯在铂电极上的电还原反应为双分子八电子三步骤电化学过程：第一步反应为准可逆单电子转移步骤，产生阴离子自由基；第二步为二电子转移步骤，并伴有随后的双分子不可逆自由基偶合反应和快速质子化及脱水反应，主要产物为氧化偶氮苯；第三步是二电子转移产生偶氮苯的过程。

In returnable system there are kinds of switch styles on positive and negative two group rectification bridger,the higher reliability is no cycle current switch ing,writer designed the logical no cycle current returnable system.

而可逆系统中正、反两组整流桥的工作切换方式有几种，可靠性较高的是无环流切换，笔者设计了逻辑无环流可逆系统。

The fibrotion pattern consists mainly of honeycombing and fibrotic scar whose pathologic lesion are irremission. KL-6 is a high molecular weigh glycoprotein found in 1980s.

前者主要包括磨玻璃影和实变影，他们所反映的病变过程可逆，后者主要包括蜂窝影，其所反映的病变过程不可逆。

Results Of the 165 cases in Uygar,51 cases were normal,and 62 cases were cerebral atrophy,porencephaly and calcification;Among the 140 cases in Han,78 cases were normal,and 26 cases were cerebral atrophy,porencephaly and calcification.

结果 本组165例维吾尔族HIE患儿中，随访复查51例恢复正常，62例均有脑萎缩、脑穿通畸形、脑钙化灶等不可逆后遗症的表现；140例汉族HIE患儿中，随访复查78例恢复正常，26例有脑萎缩、脑穿通畸形、脑钙化灶等不可逆后遗症的表现。

The major difference between these is reversibility or unreversibility of disease. If patients with acute renal failure are unable to get immediate and adequate medical care, they can progress to unreversible chronic renal failure, with a need for further dialysis or even transplantation.

肾衰竭分为急性和慢性肾衰竭，而两者最大的不同在於可逆与不可逆，然而急性肾衰竭病人若未能及时接受适当的治疗，将会演变为不可逆性的慢性肾衰竭，必要时将倚赖透析治疗或肾脏移植。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
