Results The concentration of IL-18 in tubercular pleural effusion group was (1200.34±530.25) pg/ml, while that of the malignant pleural effusion group was (240.40±80.49) pg/ml, the former was significantly higher than the latter (P.01); The analytic result of ROC curve showed that 360 pg/ml IL-18 could be seen as the critical value for diagnosis of the tubercular pleural effusion, whose sensitivity and specificity respectively was 89.2% and 93.5%.

结果 结核性胸腔积液组IL-18的浓度为(1200.34±530.25)pg/ml，恶性胸腔积液组IL-18的浓度为(240.40±80.49)pg/ml，结核性胸腔积液组IL-18的浓度显著高于恶性胸腔积液组(P.01)；ROC曲线分析结果显示IL-18以360pg/ml为诊断结核性胸腔积液的临界值，其敏感度和特异度分别是89.2%和93.5%。

Androgynus was a kind of hyperaccumulator in Cd, with critical value of 50 mg/kg, above which would cause poison in S. androgynus, and even dead when it was up to 800mg/kg; transfer coefficient would decrease with the increase in treated concentrations, which show that plant would protest Cd against transferring to above-grounds and causing poison.

以上结果说明五指山野菜是Cd超积累植物，且50 mg/kg时是五指山野菜正常生长的临界值，高于此浓度，将对其产生毒害，当浓度为800 mg/kg时，植株出现死亡；随处理浓度的增加，转移系数逐渐变小，说明植物在高Cd胁迫下阻止Cd向地上部分转移而产生更严重的毒害。

The method which is used to measure and compute moment, yield and turning angle by steel bar gauge is introduced in detail. According to the measuring results, the horizontal critical load of the testing pile is 120 kN. The steel bar gauge measuring results show that the largest moment is located in the depth from 2 m to 3 m under the horizontal load, it transfers to the deeper location with the increase of the horizontal load, and the bend distortion only occurs in the upper of 1/3 pile length.

结合实际工程详细地介绍了利用钢筋计测试水平荷载作用下桩身弯矩、挠度和转角分布的方法，根据桩顶位移和钢筋内力测试结果判定试验桩的水平临界荷载为120 kN；根据钢筋计测试结果可知，在水平荷载作用下，桩身最大弯矩截面位于在地面以下2～3 m处，且随着荷载的增大最大弯矩截面逐渐向深部转移；发生弯曲变形的部分主要是桩长1/3以上的桩体，而其下的桩体几乎不发生变形。

The results show that spectrum switch is appearing in the vicinity of critical diffraction angle c.

结果表明，在临界衍射角θc附近光谱开关出现。

The critical flow rates of sand grains with different size migrated from the sandcarrying pipe with different angle of inclination were measured.

观察了颗粒在不同倾斜角度的井筒中的运移方式，测定了不同粒径的砂粒被携带出的临界流量，揭示了颗粒直径同流体流量关系变化规律。

This type of anneal, the steel is heated slightly above its critical range and then cooled very slowly.

对于这种退火，钢材被加热到稍高于它的临界温度范围，然后缓慢冷却。

For this type of anneal, the steel is heated slightly above its critical range and then cooled very slowly.

对于这种退火，钢材被加热到稍高于它的临界温度范围，然后缓慢冷却。

The results indicate that the temperaturedependence of critical resolved shear stress depends mainly on antiphase boundary energyand CRSS of γ' phase, while the orientation dependence and strain rate sensitivity are determined byγ' phase.

摘要本文考察了镍基高温合金单晶压缩屈服行为的温度、取向和应变速率依赖性、结果表明，γ＋γ合金临界分解切应力的温度依赖性主要由γ'相的APB能和γ'相的CRSS的温度依赖性共同决定，而取向依赖性和应变速率敏感性则由γ相决定。

We find in form, the surface parts which are put in front of the time marks of the two structures are antithetic of affirmation and negation; in content, these two structures fully show their complementary distributions with their process meaning and critical meaning. And the essence of the complementary distributions is the contradiction of one-way dimension of objective time and inverse subjective thought.

从形式上看，在"没有VP之前"与"VP之前"结构的时间标记之前的表层成分是否定和肯定的对立；从内容上看，尽显"没有VP之前"与"VP之前"各自独立品格的是过程意义与临界意义的互补分布。

In spite of the slight blue shift in the LE band, the ICT band was found to shift to the blue soundly at CTAB concentration well beneath its CMC, suggesting that an apolar microenvironment is formed surrounding the fluorophore over this CTAB concentration range.

当CTAB浓度远低于其临界胶束浓度时，ICT发射带显著兰移，而LE发射带略微兰移，这表明在该CTAB浓度区域内，荧光体处于非极性微环境中。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
