The homogeneous nucleation rate, saturation rate, and droplet growth equation at state 250K、100Kpa for pentone affected by single expansion wave has been obtained in the joined international cooperation research. Results exposed that temperature decrease in the homogenous nucleation and condensation is the preponderant factor in unsteady adiabatic expansion process.

参与同质核化率实验的国际合作研究,获得250K、100KPa状态附近戊醇在单脉冲膨胀波作用下的同质核化率、饱和度及同质核化微滴在低压状态中长大状态方程;研究表明非定常绝热膨胀过程中,降温因素在同质核化和凝结过程中占主导作用。

The results showed that the composite batcher drip nozzle consisting of ceramics drip nozzle and plug had high strength, excellent toughness, abrasion resistance and corrosion resistance, and long service life. It was not easy to fracture while replacing. The new batcher drip nozzle could increase the productivity of production line and decrease the production cost of metal grains when it was used to cast metal grains.

结果表明,由烧结陶瓷加工而成的滴嘴本体及与滴嘴本体配合的塞子两部分构成的组合式定量器滴嘴,强度高,韧性、耐磨性和耐蚀性好,使用寿命长,更换时不断裂,可提高铸造金属颗粒生产线的作业率,降低金属颗粒加工成本。

The steady-state principle of constant-head well permeameter, which was used to calculate the field-saturated hydraulic conductivity, was applied to quantify the suitable emitter discharge rate for indirect subsurface drip irrigation under different water-conducting device specification conditions in this text. Using the calculated emitter discharge rate to supply water, characteristic parameters of wetted soil volume were studied during the water movement process.

该文将恒定水头钻孔积水入渗求解土壤饱和导水率的稳态原理用于定量化求解间接地下滴灌技术中与任意导水装置尺寸相匹配的滴头流量,并以计算的技术参数为基础,研究了间接地下滴灌水分运移过程中的土壤湿润体特征参数。

Objective:in order to compare the curative effects of using lamirudine and thymosin together with using thymosin only to the paients of chronic hepatitis b.methods:we had chosen 27 medical cases of chronic hepatitis b,which were divided into two groups:15 cases asone group,and 12 cases as the other group.let group a take 100 mglamirudine orally,qd,with half a year as a period of treatment.at the same time givethe patients injections of 100 mg thymosin,qd,for a month.to group b was only takenlamirudine.alt,tbil,the indicators of the virosis of hepatitis b (hbsag,hbeag,hbv-dna)were observed as quatos.results: at the end of the treatment, the rates that groupa and group b made hbsag transform into negative were respectively 26.67% and 16.67%(p>0.05);hbeag:33.33%,8.33%;hbv-dna:53.33%,33.33%(p>0.05).conclusion:combining thymic peptide with 3tc to treat chronic type b hepatitis, thymic peptide will not only promote b-cell to mature and transformation, but also to keep the subpopulation of t-cell in immune system in balance, which can enhance the reaction of matured t-cell to the antigen or other stimulus.

目的:比较拉米夫定(3tc)与胸腺肽联用和单用拉米夫定治疗慢性乙型肝炎的疗效。方法:选择慢性乙型肝炎患者27例,分为联合组15例和拉米夫定组12例;联合组用拉米夫定100 mg,口服,qd,疗程半年,合并用胸腺肽100 mg,静滴,qd,疗程1个月。拉米夫定组单用拉米夫定。以谷丙转氨酶、血清胆红素、乙肝病毒标志物(hbsag,hbeag,hbv-dna)为观察指标,比较不同治疗方案对指标的影响。结果:治疗结束时联合组与拉米夫定组对慢性乙肝患者血清hbsag阴转率分别是26.67%和16.67%(p>0.05);hbeag阴转率分别是33.33%和8.33%(p>0.05);hbv-dna阴转率分别是53.33%和33.33%(p>0.05)。结论:胸腺肽联合3tc治疗慢乙肝,胸腺肽具有促进t淋巴细胞的成熟和转化,并维持免疫系统各t淋巴细胞亚群间的平衡作用,能增强成熟t淋巴细胞对抗原或其他刺激的反应。
