在表征表面超疏水性时，除常用的θ、α外，接触角滞后Δθ、斜面上液滴滞留在材料表面上的最大半径Rc、两种状态转化时的临界压力Δp以及液滴落下后能反弹的临界撞击速度Vc也是非常重要的参数。

Distinguishing from the former researches about CR service communication interruption, only spectrum handoff times exceed a certain number, communication interruption will occur. This strategy can reduce the COP of CR services.(3) Some coexistence issues between WRAN and DTV system are studiedFirstly, the network architecture, system parameters, and self-coexistence of Wireless Regional Area Network are investigated, and convergent performances among overlapping Base Station are simulated and validated. Then, a simple coexistent scenario between WRAN and Digital TV is designed to analyze the interference from WRAN BS to DTV receiver.

3研究了WRAN和DTV系统共存时的若干问题首先对无线区域网(Wireless Regional Area Network，WRAN)本身网络结构、系统参数和自共存机制进行了研究，仿真验证了WRAN重叠覆盖区基站(Base Station，BS)之间同步的收敛性能；接着设计了一种分析WRAN BS干扰数字电视(Digital TV，DTV)接收机的共存场景，通过研究发现了一些干扰控制的临界值，这些临界值对于WRAN的设计和部署具有指导性意义。

Research shows that temperature, slenderness ratio, section forms of rods, and covering layer thickness to members under fire conditions have a sizable effect on critical load and length of rods, but the effect of rod dead load may be overlooked.

研究表明，温度、长细比、杆件截面形式、保护层厚度对杆件稳定临界荷载和临界长度影响较大，构件自重的影响可忽略，在此基础上给出了不同约束条件下杆件的计算参数。

Firstly, based on the acidity balance equation in ecosystem, together with the steady state mass balance equations of sulphur and nitrogen, formulae for calculating critical loads of not only acidity and sulphur, but also acidifying nitrogen and nutrient nitrogen were educed.

基于原有的生态系统酸度平衡关系，并结合临界状态下硫和氮的稳态质量平衡，推导出计算酸度、硫、酸化氮和营养氮临界负荷的公式。

This is the socalled thin layer penetrating air drying process. The critical thickness of wet silkworm chrysalises is about 27~35 mm. In the thin layer penetrating gas drying process of silkworm chrysalises, the temperature of drying medium is subject to that at which the protein can withstand and the flow rate is subject to the allowable leakage of air from the media layer; c. For the surface convective drying process of stripe porous media e.

对于粒状多孔介质的穿流气流干燥过程，当物料厚度小于某一临界厚度时，厚度的变化对干燥过程无明显影响，即所谓薄层穿透气流干燥过程，就蚕蛹而言，临界厚度约为27~35mm；在蚕蛹薄层穿流气流干燥过程中，介质温度应以蛋白质所能承受的温度为限，流速应以穿流料层时不发生漏风现象为限；c。

When a thread owns a critical section, it can make additional calls to EnterCriticalSection or TryEnterCriticalSection without blocking its execution. This prevents a thread from deadlocking itself while waiting for a critical section that it already owns.

但一个线程获得临界区时，如果再次调用 EnterCriticalSection 或者 TryEnterCriticalSection 将不会使其阻塞，这就预防了线程在等待一个自己已经拥有的临界区时死锁自己。

In the example, the critical remote strain and the buckling configuration for different length-to-thickness ratios of delaminating are given.

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。
