The effects of gap size, shape, inclination angle, pressure and form losses of two ends of annuli were discussed. Based on experimental data and theoretical analysis results, a new half-empirical correlation was also derived which can accurately predict the CHF of vertical annuli, circle tube and rectangular channel in a very wide range of H/De values.

在实验和理论分析的基础上，提出了一个新的，可用于计算竖直环隙、圆管及长方形流道内自然对流沸腾临界热负荷的半经验公式，其计算精度和适用范围较现有的计算公式有显著提高，原则上不受H/De值大小的限制。

Its production of the CT40-10 / H built-in high-voltage electrostatic generator, a Japanese import circuit, a very light weight of the spray gun (only 450 grams), and for the stainless steel powder extinguishers.

其生产的CT40-10/H内置式高压静电发生器，采用日本进口电路、重量极轻的喷枪（仅450克）和全不锈钢的供粉筒。

High-resolution 〓H-NMR spectra were used to confirm the formation of the ICs, and XPS spectra were used to corroborate the formation of S-Au bonds. The significantly improved"reversible"voltammetric responses and the reproducible surface coverages of (2.4±0.2)×10〓 and (2.2±0.2)×10〓 mol/cm〓 obtained for SAMs of β-CD/C〓VC〓SH and α-CD/C〓VC〓SH, respectively, indicate that the intercalated CD can effectively dilute the surface viologen groups and weaken the intermolecular interaction, giving a wellordered and viologen-containing SAM with a determinate surface coverage.

高分辨〓H-NMR谱确证了预期包络物的形成；XPS谱确证了包络物电活性自组膜和S-Au共价键的形成；明显改善的&可逆&伏安响应和重现的紫精基团表面覆盖度[对β和α分别为(2.4±0.1)×10〓和(2.2±0.1)×10〓mol/cm〓]，表明嵌入的环糊精可有效地&稀释&紫精基团，在很大程度上减弱它们之间的相互作用，形成了完备的和有确定紫精覆盖度的包络物电活性自组膜。
