隔离的

Comparing the synchronous rectifier to normal circuit by calculating the efficiency indicates that forestay is much better on efficiency and thermal performance. A simple circuit with good consistency, high efficiency, high reliability and low cost is presented in this paper. The feasibility is proved by emulating with computer.

The results of the test show that the whole intensity and comprehensive stability of subgrade made a good progress because the capillary water cant rise by using the insulating layer. In the prior condition of taking insulating layer thickness as 0.2m, choosing insulating layer 0.5m, 0.8m, below the pavement, the stability of seasonal frozen soil subgrade is analyzed. The results of the test also show that the optimal position of the insulating layer is 1.0m～1.5m .

试验表明，由于隔离层的作用使得毛细水无法迁移，对路基整体的强度和综合稳定性都有了很大程度上的提高，同时试验还表明在隔离层厚度为0.2m的前提下，设置在距路面以下1.0m～1.5m位置，即路基表面以下0.5m～0.8m处对路基的稳定性最为有利。

He renounced his claim to the chieftainship because he didn't want to oppress the people as a ruler. In 1944,he joined the African National Congress, known as ANC, a black-liberation group ,and in 1949 he became one of its leaders , helping to revitalize the organization and opposing the apartheid policies South Africa's official system of segregation and discrimination against the country's nonwhite majority. In 1960, after the police shot more than 200 unarmed black protesters at Sharpeville and the government banned the ANC, Mandela abandoned his nonviolent stance and began to advocate acts of sabotage.

他因为不愿意做一个压迫人民的统治者而放弃了酋长的继承权。1944年，他加入了非洲国民大会，也称"非国大"，一个解放黑人的组织，并在1949年成为该组织的一名领导，帮助重新振兴这个组织和反对种族隔离政策--南非对占这个国家人口绝大多数的非白色人种的隔离和歧视的官方制度。1960年，警方在沙佩维尔射杀了200多名手无寸铁的黑人抗议者，同时政府取缔了非国大。

This paper, in the light of Pierre Boudieu's notion of social identity, tries to demonstrate the irresistibility of such separateness and the unavoidability of the conflict of social identities in the context of colonialism.

本文从社会学的角度，试图通过个体的社会认同之间的冲突来诠释这一隔离感，并认为在特定的殖民主义背景下，这一隔离感源自社会认同的冲突，是不同社会群体之间利益斗争的必然产物。

His hope was to create a basketball team from a selection of boys from each school, which were on opposite sides of a 50-foot-wide, mile-long dividing wall that was erected to prevent exactly what Michael was aiming for -- bringing the two communities together.

他的希望是从两所学校各选出一些男生来组建一只篮球队。两所学校之间竖立的是高50英尺、一英里长的隔离墙。而隔离墙的目的就是为了阻止Michael所瞄准的目标--让两个社区走到一起。

In this method,fault detection is based on functional test for circuit boards, and fault isolation is based on the com- parison of actual response and expected response on correlative nodes,Besides, the aproach of building diag- nostic database and hardware composition of test system is introduced,According to this method,a practical test system has been made successfully.it can isolate 80% faults to nodes.

在该方法中，故障检测是基于对电路板的功能测试，故障隔离是基于相关节点的实际响应和预期响应的比较，此外还介绍了诊断数据库的建立方法以及测试系统的硬件组成。根据这一方法已研制成功一个实用测试系统，它能把80％故障隔离到节点。

In order to be able to drive three separated speed controllers I wanted to be able to isolate the output stages of the controllers to prevent possible unpredictable high current loops between circuits, this also allows us to run one or multiple batteries safely so I experimented with some designs, The opto isolator device (4N35) can be inserted at various strategic parts of the circuit and in fact it is often at the front end at the receiver input but I chose to isolate just the output stage as I will be adding the other channel circuitry to the same receiver and battery eliminator circuit voltage rails.

在为了能够驱动器3分离速度控制器，我想能够隔离输出阶段的控制器，以防止可能出现难以预料的高电流环路之间的电路，这也使我们能够运行一个或多个电池安全，使i试行了一些设计，光电隔离器装置（ 4n35）可以插入各种战略的部分电路，并在事实上它往往是在前端，在接收器输入，但我选择了孤立刚输出阶段，因为我会加入其他渠道电路，同时接收器和电池消除电路的电压轨。

More fine and lighter dust particles are fetched into the upper by the upper spiral airflow, forming strong spirally ash hoop at the inside of the top gap and bringing forth the accumulation of the dust particles, then are drawn forth from the upper entrance of special dust insulator, through the lower helical groove of dust insulator, tangential admission to the dust collector from the air return mouth of the dust collector's outside.

较细较轻的灰粒，由上旋涡气流带往上部，在顶盖下面形成强烈旋转的灰环，产生灰粒的集聚，并被从特设的灰尘隔离室上部洞口引出，经过灰尘隔离室的下部螺旋槽，从除尘器外壁回风口切向引入除尘器，筒体下部与内部气流汇合，灰粒被分离而落入灰斗。

Firstly, a mathematic model was constructed to deal with fault isolation. This model mainly considered the associations among fault sources and available testing of hierarchical system, the affiliation of faults with replaceable units in different levels, the prior probability of fault sources and the available testing costs. Secondly, a quasi multi-step look-ahead search algorithm was presented which employed the information gain as its heuristics. This algorithm could realize optimization of testing sequence in different isolation levels.

首先基于层次系统故障与测试之间的关联关系，以及故障与不同层级可更换单元的隶属关系，结合故障的先验概率与可用测试成本，构造了层次系统故障隔离问题的数学描述模型；然后以信息增益为启发策略，提出了一种准多步前向搜索算法，实现了不同隔离级的测试顺序优化。

Peasant-worker order construction means a process of voluntarily separation and self-close, a process of social moral separation and moral keynote re-cognition, a process of reconstruction of social order in low estate and in the urban.

农民工在城市中的秩序建构过程体现为一种&自愿性隔离&和&自我封闭&的过程、一种社会道德隔离和一种道德基调确认的过程、一种底层生存秋序建构的过程和城市秩序建构的过程。

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）。
