By applying Lebesgue s measure on the symmetric difference of sets,the p mean symmetric difference metric d Δp is established to measure the difference between Fuzzy numbers,and it is proved that d Δ p is a complete pseudo metric on space E(K)={A~|A~∈E 1,A 0K,K∈I(R)},and it is illustrated by examples that (E 1,d Δp ) is not complete pseudo metric space.
从集合的对称差集合的 L ebesgue测度出发 ,建立了衡量 Fuzzy数之间差异的p-平均对称差度量 dΔp,证明了 dΔp在空间 E1(K) ={ A~ |A~ ∈ E1,A0 K,K∈ I(R) }上是完备的拟度量 ,并举例说明 (E1,dΔ p)不是完备的拟度量空间。

In this paper, on the basis of the analysis of the characteristics of wind-blown-sand flow in view of gas-solid two-phase flow, the sand incipience process was realized and observed by using Particle Imaging Velocimeter (PⅣ) technique in a specially designed test facility and the influence factors were discussed.
本文在对风沙流进行气固两相流分析的基础上实现了低风速条件下的沙粒起动过程,借助PⅣ测量系统对其进行了观测并对影响因素进行了分析,获得了沙粒的浓度和速度分布。

低肌张力低智能性发育低下肥胖综合征


病名。简称HHHD综合征。亦称PraderWilli综合征。主要因下丘脑功能紊乱而致。无明显家族因素。男性多见。包括出生时肌张力及反射低下,嗜睡,哺乳喂养困难及6个月后肌张力亢进,过食,肥胖,智能低下,小阴茎,双侧或单侧隐睾,青春期副性征不发育,高血糖症,糖尿病等。宜对症治疗。
