有四种

Possible interaction effects of individual learning style and instructor-students interactive modes on learning effect were also examined. This study used the Kolb's learning styles inventory to classify learners into four groups including Accommodator, Diverger, Assimilator and Converger respectively.

本研究透过实地实验的方式来验证，学习风格依据Kolb学习风格型态理论为基础所定义的学习风格分为「发散者」、「调适者」、「聚敛者」、「同化者」等四种类型的学习者；师生即时传讯则采「即时传讯互动」与「无即时传讯互动」两种方式来进行程式设计课程内容，以验证即时传讯互动方式应用在程式设计课程上是否真有其实质效果，并以学习绩效、认知学习、学习兴趣、认知技能发展与教学设计满意等五个构面来衡量学习成效。

The transfer behavior of pyrazolone derivatives, such as antipyrine, aminopyrine, 4-aminoantipyrine and analgin, across the W/NB interface was investigated. The three medicines studied can form complex with a proton and the complex formed can transfer reversely across the W/NB interface and the transfer process was controlled by diffusion. The transfer of protonated analgin was not observed within potential window because of its high transfer potential.

研究了吡唑啉酮类的安替比林、氨基比林、4-氨基安替比林和安乃近四种药物在W/NB界面的转移行为，前三种药物在一定pH值的水溶液中结合一个质子形成1∶1质子配合物，并能在W/NB界面发生可逆转移，其转移过程受扩散控制，安乃近的质子化物由于有较高的转移电位而未在电位窗内观察到其转移峰。

We proposed the simplest structure of 2-D bilinear transformation digital circuit, we proposed four approaches of the realizations:(1) Realization of 2-D discrete domain difference equations;(2) 2-D FFT realization;(3) Digital hardware implementation;(4) by 2-D recursive digital structure to realize them.

在第七章，我们则重点研究了二维数字滤波器的实现问题。我们对第六章提出的2-D双线性变换电路又作了进一步的简化，获得了一种最简结构的二维双线性变换数字电路，该电路仅有二个延时器和一个乘法器。在第七章里，我们提出了二维跳耦型数字滤波器的四种实现方法：(1)二维时域差分方程实现；(2)二维FFT实现；(3)数字硬件实现，(4)用2-D递归数字结构实现。

Carl Sagan has entertainingly described this phenomenon, musing about the destiny of bacteria that reproduce by dividing into two every 15 minutes. Says Sagan:"That means four doublings an hour, and 96 doublings a day. Although a bacterium weighs only about a trillionth of a gram, its descendants, after a day of wild asexual abandon, will collectively weigh as much as a mountain...in two days, more than thesun - and before very long, everything in the universe will be made of bacteria." Not to worry, says Sagan: Some obstacle always impedes this kind of exponential growth. The bugs run out of food, or they poison each other, or they are shy about reproducing in public.

Carl Sagan 曾经开玩笑地解释这种现象，假设有一种细菌每15分钟可以分裂一次，亦即代表每一小时复制四次，一天可复制96次，虽然单一个细菌其重量只有一兆分之一公克重，但是只要经过一天无止尽的无性生殖，其重量可能会比一座山还重，经过两天后，甚至会比太阳还重，要不了多久所有的宇宙都将由这种细菌所组成，不过 Sagan 又说，大家不必担心，上天一定会安排障碍来阻止其倍数成长，有可能他会耗尽食物，或是毒死自己，或是有可能羞于在大庭广众之下复制。

The results indicated that AKP exist in all tissues and organs of Andrias davidianus, which were mainly 230 and 200 KD. Activity of AKP in different tissues and organs was different, and these were strongest in heart and weakest in eyes. In the same tissues and organs, two kinds of AKP activities were different.

结果表明，二十四种组织器官中都有碱性磷酸酶存在，其中230和200 KD的碱性磷酸酶占优势；不同组织器官的碱性磷酸酶活性有差异，心脏中活性最强，眼球中活性最弱；在同一组织中，230和200 KD的碱性磷酸酶活性也有差异。

Base on core observation and grain size analysis, and under associated consideration of logging trace characteristics, Chang8 reservoir in study area is classified into three sedimentatal microfacies, subsea river, mouth bar and river flank.3.The mian diagenesis in study area are: mechanical compaction, cementation, metasomasis and denudation in late diagenetic phase.4. In allocation of reservoir macroscopic heterogeneity, more heterogeneticer reservoir, class 1 and class 2, mainly locate in the center of subsea river or crook and divaricate of the river; class 3 and class 4 mainly locate in river flank, and the physical property of these locality are better.5. Diagenesis of reservoir have influence on the pore structure which influences the reservoir microscopic heterogeneity. The better the pore structure is, the slighter the reservoir microscopic heterogeneity is; on the contrary, the reservoir microscopic heterogeneity is serious.

本次研究所取得的主要成果及熟悉有：1、将合水地区长8储层细分为6个小层：长8_1~1、长8_1~2、长8_1~3、长8_2~1、长8_2~2和长8_2~3.2、依据岩心观察和粒度分析，并结合测井曲线特征，研究区长8储层分为水下分流河道、河口坝和河道侧翼四种沉积微相。3、研究区主要经历的成岩作用有：机械压实和压溶作用、胶结作用、交代作用、晚成岩期溶解作用。4、从宏观非均质性平面展布特征来看研究区宏观非均质较强的1类和2类区主要分布于水下分流河道中间或河道拐弯和分又处。3类和4类往则主要分布于水下分流河道侧翼，这些地方储层均质性相对较好。5、储层成岩作用影响储层的孔隙结构，储层的孔隙结构又对储层的微观非均质性有不同程度的影响，孔隙结构越好，则储层的均质性越好，储层的孔隙结构差，则非均质性强。

The researchers used the Lesch typology to classify patients into four types of alcohol dependence: type 1, those who suffer from heay alcohol withdrawal and use alcohol to weaken the withdrawal symptoms; type 2, indicating those who use alcohol for its anxiolytic effects; type 3 ("depression"), coering patients who hae an underlying affectie disorder that accounts for the alcohol abuse; and type 4 ("adaptation"), applied to those who hae premorbid cerebral defects, behaioral disorders, and a high social burden.

研究者使用lesch类型学把病人分为四种酒精依赖型：1型，那些遭受沉重酒精戒断症状并使用酒精减轻戒断症状的人；2型，表示那些依赖酒精的镇静效果的人；3型，涵盖有可导致酗酒行为的潜在情感障碍的病人；而第4型，适用于那些有病前脑缺陷、行为失常或有很高社会负担的人。

For the mode of legislation, it is suggested that a principle regulations to be made while the detailed applied situation and conditions are specified further in judicial explanation; regarding the applied situation, give four kinds of examples as shortage of capital, mixing of company, property of shareholders, business and personality, avoid the liability of contract and legal liability using of company personality; when making judgment, such three parts as main body, action and results have to be considered. The voluntary creditor and forced creditor consists of prosecutor, those person who abuses the force of company is the defendant who has the act of abusing company personally resulting in bad effect; the responsibility of producing of evident may refer to those of courts of Germany, which is proved by prosecutor, after that, the defendant provides the evident that he has a proper action for the suit of company or his action is not the direct cause for the loss of company; the legal effect of disregarding of corporate personality is to deprive the rights of limited liability of shareholders and shall undertake the affiliated liability according to different situations of company debts, however, it is clear that the legal effect is only limited to the special legal relationship in the specific case; the exercising body is made by court while the corporate personality might not be disaffirmed directly in exerting process; finally, it points out the real essence and also its real sense and difficulties in practice.

对立法模式，建议成文法中只做原则性规定，而具体的适用情形、适用条件等规定可以在司法解释中进一步作出明确规定；对适用情形，根据我国实际列举了资本显著不足、公司与股东财产、业务、人格的混同、利用公司人格规避契约义务和逃避法律义务四种大类；审判时应考虑的要件包括主体、行为、结果三大要件，自愿债权人和非自愿债权人构成原告，对公司有控制力的滥用者为被告，要有滥用公司人格的行为，并有损害的结果产生；举证责任可参照德国法院的做法，由原告提供初步证据证明公司存在滥用公司人格的行为，而后，由被告提供证据证明自己与涉诉公司的关系是正当的，或自己的行为与原告的损失没有因果关系；否认公司人格的法律效果是剥夺股东在个案中的有限责任的权利，视不同情形对公司债务承担连带责任，但应明确法律效力仅限于个案中的特别法律关系；行使主体应由法院的审判庭行使，而不宜在执行程序中直接否认公司法人人格；最后对逆向揭开公司面纱作了探讨，指出其现实意义和实践难点。
