A projectile with ground-air rocket by the burst of TNT has been designed for dispersing metaldehyde(MA)into the clouds on a large scale. The threshold temperature of MA on ice nucleation in laboratory is around -1℃. The projectile is made of proper dosage,with TNT in its core and-MA in its outer layer.The result of the experiment for explosion shows that the number of MA particles dispersed by the burst of TNT reaches the order of 10~(12) I/gm and that of ice nucleation is 10~7~10~(10)1/gm in the temperature...

A projectile with ground-air rocket by the burst of TNT has been designed for dispersing metaldehyde(MA)into the clouds on a large scale. The threshold temperature of MA on ice nucleation in laboratory is around -1℃. The projectile is made of proper dosage,with TNT in its core and-MA in its outer layer.The result of the experiment for explosion shows that the number of MA particles dispersed by the burst of TNT reaches the order of 10~(12) I/gm and that of ice nucleation is 10~7~10~(10)1/gm in the temperature range of -1℃~-15℃. The quantitative analyses of collected products for explosion show that the loss of MA due to burning or decomposition augments with the increasing amour of TNT used,but its remains are more than 71%. The ability of forming ice of MA which has been stored for one year or more decrasses by about one order of magnitude. The result of the experiments of quick toxicity on account of ingested AM shows that the the L_(D50)for large rats counted by means of Horn's method is 316 mg/kg,the limit of 95% Confidence is 169~592 mg/Kg. For the sake of comparison,some experimemts ofice nucleation of AgI have been carried out in the laboratory,showing the number of ice crystals is 10~6 1/gm~10~(12)1/gm within -5℃~13℃. In comparison with the ice nucleation ability of AgI-acetone solution,it is shown that MA is more efficient than AgI to modify the supercooled clouds above -6.5℃.

为了地面利用小火箭有效地对云大量撒播介乙醛,我们设计了一种用 TNT 分散介乙醛的药桂。室内实验测定介乙醛的成冰阈温在-1℃左右。选取合适的配方压制以 TNT 为内芯,介乙醛在外层的药桂。爆炸试验表明:介乙醛产生的微粒数达12~(12)个/克,在-1℃~15℃范围内产生的冰晶数为10~7个/克~10~(10)个/克以上。对爆炸后收集的产物分析表明:介乙醛因燃烧或分介的损失量随 TNT 用量的加大而增加,而其保存量均在71%以上。贮存一年以上的介乙醛,其成冰能力降低一个量级左右。介乙醛急性经口毒性试验表明:大白鼠用 Horn 氏法计算 L_D50为316毫克/公斤,95%的可信限为169~591毫克/公斤。为了对比起见,对 AgI 的成冰能力也作了爆炸试验,实验表明:在-5℃~13.5℃范围内,AgI 产生的冰晶数为10~6个/克~10~(10)个/克。将介乙醛与 AgI-NaI-丙酮溶液的成冰能力相比较,发现温度高于-6.5℃时,作为冷云催化剂来说,介乙醛比 Agl 要更为有效。

The present paper which has been chiefly contributed toward a studying on hot-pre-ssing silicon nitride doped with 5%(wt) magnesia is divided into three sections:(1)Manufacture——by proper choice of flowing rate of gases, temperature and duration ofnitridation, we have succeeded in preparing a raw material containing 90~95%ofα-siliconnitride.The selection of technological parameters of hot-pressing including temperature,pressure and time are described.(2)Physical and mechanical properties——the bending strength of specimens preparedunder optimun technological conditions is 7500~8200kg/cm~2 at room temperature or 7000kg/cm~2at 1100℃, and it begins obviously to decrease at 1200℃. The specimens prepared are qui- te resistant to oxidation up tO 1200℃, however at 1400℃ their oxidation rate is rapidlyincreased, the weight gain in an air environment at 1300℃ obnys roughly the parabolicrule.The abrasion coefficient is considerably small at wearing against steel №45, the dryabrasion coefficient is determined to be 0.5, and it is lowered further down to 0.09~0.11while the wearing parts have been lubricated.Thermal expansion coefficients from roomtemperature to 1200℃ are α=1.75~2.95×10~(-5). and hardness H_R=91~92. (3)Microstructure and wetting angle measurement-the electron micrographs have re-vealed that the hot-pressing bodies have a texture of equiaxial grains of silicon nitride inter-laced with fiberous grains. The wetting angle of silicon nitride by MgO .SiO_2 and 2MgO.SiO_2 melts approaches 20°.Therefore it may be reasonably thought that the liquid phaseformed at high temperatures would take an important part in sintering process. Finally, the effects of technological parameters on the strength of hot-pressing siliconnitride were also discussed, and therefrom the approaches to the improvement of hightemperature strength were suggested.

本文主要研究添加5%(重量)MgO为助熔剂的热压氮化硅系统,分为以下三部分: (1)氮化硅制备工艺。通过选择适当氮化温度、时间和气体流量,能制备α相控制在90~95%范围内的Si_3N_4粉末。同时叙述了热压工艺:包括温度、压力,保温时间等工艺参数的选择。 (2)热压氮化硅机械物理性能:室温强度在7500公斤/厘米~2~8200公斤/厘米~2,1100℃时强度为7000公斤/厘米~2,1200℃时开始下降明显,1200℃以下抗氧化性良好,1400℃氧化速率迅速增加,1300℃的氧化增重基本上符合抛物线规律;摩擦系数小,与45~*钢对磨时干摩擦系数为0.5,有润滑油情况下,为0.09~0.11;从室温到1200℃的膨胀系数α=1.75~2.95×10~(-6);硬度H_R=91~92。 (3)热压氮化硅微观结构观察和润湿角测定。电镜照片表明其织构主要由纤维状形貌颗粒和部分等轴形貌颗粒组成。Si_3N_4与MgO·SiO_2和2MgO·SiO_2的润湿角接近20°,表明它是有液相参与的烧结。 本文还对一些工艺因素变化与强度关系进行讨论,并指出进一步改进高温强度的途径。

Liquid membrance extraction are a new and effective technique for separation of mixtures. They are made by forming an emulsion of two immisicible phases and then dispersing the emulsion in a third phase(the continuous phase). In this paper, we have treated the phenolic waste water, which contains 300-950 ppm of phenol, with liquid membrance, i. e. NaOH solution in oil. In proper condition, 98% of phenol may be removed and the breakage of the emulsion drops are less then 1 % per hour. The overall diffusivities...

The overall diffusivities of phenol through the liquid membrance are also calculated and they show to be a constant.

液膜是用于混合物分离的一种新型有效的技术。它是由两个不混溶相形成乳液,然后将乳液在第三相(连续相)中分散而成。在本工作中,我们应用在油中含有NaOH溶液的液膜处理了含酚为300—950ppm的含酚污水。在适当的条件下,可以使98%的酚脱除,而乳泡的破裂每小时小于1%。计算了酚通过液膜的总包扩散系数,结果表明是一个常数。
