When babbitt is casted on the surface of cast iron, it is not easy for the babbitt to bond with cast iron as it does with steel, because cast iron contains more impurities, such as carbon, silicon, etc., especially the graphite which interrupts the babbitt from bonding with iron. An acid solution of rather high percentage of hydrofluoric acid for pickling is used with an attempt of producting a rather pure iron layer on the surface of cast iron.

When babbitt is casted on the surface of cast iron, it is not easy for the babbitt to bond with cast iron as it does with steel, because cast iron contains more impurities, such as carbon, silicon, etc., especially the graphite which interrupts the babbitt from bonding with iron. An acid solution of rather high percentage of hydrofluoric acid for pickling is used with an attempt of producting a rather pure iron layer on the surface of cast iron. The iron articles, so treated, are then rinsed with hot water and cold water, and transferred into a solution of alkaline salt to boil for more than half an hour. The surface for reaction is, then, heavily brushed with fine copper brush. After washing in running wa er and passing through a solution of hydrochloric acid solution, the cast iron is then fluxed in a hot solution of zinc chloride and finally transferred to the metallic bath for "tinning". The process of "tinning" should be carried out under strictly controlled temperature and time of soaking. After"tinning", the lining of babbitt metal is poured on the surface of cast iron in a permanent mould and the rate of cooling should be carefully observed. A number of tests of the articles, so babbitted, show that the bonding force between cast iron and the babbitt is above 302 kg/cm~2. If the centrifugal casting method were used as in the manufracture of bearing, the bonding force could be expected to be stronger.

在铸铁面上粘牢一层巴氏合金,对动力工业或机械工业都很有用,但铸铁含有的炭,矽,錳磷硫等杂质较钢为多,特别是游离炭,它阻碍巴氏合金与铸铁的粘牢,这里的研究是用酸性溶液来在铸铁面上进行产生较纯的铁层,然后用鹹性溶液沸煮,并用软铜丝刷重刷铸铁需加合金之一面,通过鹽酸溶液,及热的氯化鋅溶液,然后进行镀焊剂及浇入巴氏合金,在鍍焊剂时,必需严格控制温度与时间,而在浇入巴氏合金时必需控制铸模温度和浇铸温度,合金铸入后冷却情况亦需适宜。用这样的方法来把巴氏合金浇铸在铸铁面上,其粘牢程度很好,经过很多次的试验机试验,得到铸铁与巴氏合金间的粘牢力是320公斤/厘米~2,这是为适合一股工业上应用而在靜模浇铸所得的结果。如专为制原动力机的軸承的话,可用离心浇铸,这样,铸铁与巴氏合金间的粘牢力还可较上面所得数字高一些。

Experiments were carried out with more than 70 varieties and 30 cross combinations over three years to study the development of some characters in the tomato plant in Shenyang area.The following primary conclusions have Leen drawn. 1.Under the condition that seedlings are raised in hot bed and trans- planted to the open in early May,the growth period from the time of sowing to first harwest requires about 135 days;and it can be subdivided into the follwing stages,namelyi,the germination stage(12.5±6.5 days),the seedling stage(29.5±5.5 days),the flower development stage(35±8 days),and the fruit development stage including the flowering stage(58±10 days).Flower bub differentiation usually begins during the appearanue of the fourth leaf. Within the growing season,the shortest growth period occurred while seed were sown in June,and under such condition the time required from seedling (?)mer gence to first harvest needs only 80 days. 2.Temperature is the main factor which influences the length of the second developmental stage,which is shorter with mean temperature above 20℃ than it is around 15℃.The main factor that influences the length of the third developmental stage is the intensity of light.The effect of other factors such as the daily mean temperature,deposition of rainfall and others within the range of seasonal variation seems to have only minor importance.With the fourth and fifth developmental stage,temperature is still the main influencing factor. 3.Earliness of maturity has been found to be dependent Loth upon the time of flowering and the length of fruit development period.Under ordinary cultural condition it depends more upon the length of fruit development period, while under condition unfavorable for flower bud differentiation it depends more upon the flowering time. 4.The position of the first inflorescence varies with the growth condition of seedlings,and its year-round curve(including greenhouse culture)appears to have two peaks,i.e.higher in Spring and Autumn Sowing,lower in Summer and Winter Sowing.This is also true with hybrid seedlings.It seems that und- er ordinary condition light intensity and the daily amplitude of temperature are the two main factors which affect the position of the first inflorescence. 5.No significant correlation was found letween earliness and the position of first inflorescence.The Conventional hypothesis which postulates,the existe- nce of this correlation calls for further consideration. 6.There is no significant correlation existing between the length of fruit development period and the size of fruit finally attained.The length of fruit development period seems to be determined mainly by the rate of development in early stage with mean temperature above 20℃ which is found to be more rapid than that of 15℃.Fruits that have reached the size about half of their final diameter require about 25 days for further development to reach maturity under all experimental conditions.Tomato fruits require about 800℃ of summ- ation of mean daily temperature to develop from fertilization to maturity.Ho- wever,early varieties may be satisfied with temperature summation lower than this,while late varieties may require a little higher than this. 7.Continuous selection of the early ripening fruits from early maturing plants results in gradually dropping of the mean fruit weight. 8.when plants were prunned to set only with three trusses of fruits,the varietal difference expressed as average yield to the plant was found to have no significant correlation with the mean number of fruits to the plant out to dep- end mainly upon the mean fruit weight of the variety. 9.The distribution of yield within the harvesting period from June to August may roughly be expressed by a curve with only one peak.If the yield is counted by every ten days,then most varieties reach their highest yield at the third or fourth time of picking.Generally,the first three pickings have already yielded about 70—90% of their total products.lnorder to utilize the land more economically a harvesting period lasting 30—40 days should be considered as suitable. 10.Most F_1 hybrids are superior to the paxents as regard to the earliness of maturity,productivity,and high yield on the early stage.Among the varieties which have been tested,“Bison”,“Bounty”and“podaleaskovsky”axe better parents for protucing early and productive F_1 hybrids.

本文是从1954年起到1957年三年多时间内在渖阳对总共七十多品种和三十多杂交组合的番茄的一些性状的观察研究总结,初步结论有以下几点:一、在渖阳地区春冬温床育苗的情况下番茄从播种到初次收获约需135天,其中发芽期为12.5±6.5天,幼苗期29.5±5.5天,花器发育期为35±8天,果实发育斯包括开花期在内为58±10天。花芽分化开始于第四真叶出现时。在一年之中6月播种的物候期最短,从出土到初次收获仅80天。二、影响第二发育分期长短的主要因素是气温,凡是平均温度在20℃以上的都比在15℃左右的短。影响第三发育分期长短的主要因素是光照强度。在自然气候变异幅度内的温度降水量等因素虽有影响但不及光照,影响第四和第五发育分期长短的主要因素也是温度。三、花期早晚和果实发育期的长短对早熟性有大致相等的重要性。在通常温床育苗情况下受果实发育长短的影响较大,当幼苗期条件不利于花芽分化时则受花期早晚的影响较大。四、第一花序节次的高低随育苗环境条件而变。在一年中有二次高低节次变化(包括温室栽培在内)即春秋低冬夏高。杂种也表现相似的趋势。节次的高低似乎主要决定于光照强度和日温差大小。五、第一花序节次的高低和品种成熟期的早晚并无一定...

本文是从1954年起到1957年三年多时间内在渖阳对总共七十多品种和三十多杂交组合的番茄的一些性状的观察研究总结,初步结论有以下几点:一、在渖阳地区春冬温床育苗的情况下番茄从播种到初次收获约需135天,其中发芽期为12.5±6.5天,幼苗期29.5±5.5天,花器发育期为35±8天,果实发育斯包括开花期在内为58±10天。花芽分化开始于第四真叶出现时。在一年之中6月播种的物候期最短,从出土到初次收获仅80天。二、影响第二发育分期长短的主要因素是气温,凡是平均温度在20℃以上的都比在15℃左右的短。影响第三发育分期长短的主要因素是光照强度。在自然气候变异幅度内的温度降水量等因素虽有影响但不及光照,影响第四和第五发育分期长短的主要因素也是温度。三、花期早晚和果实发育期的长短对早熟性有大致相等的重要性。在通常温床育苗情况下受果实发育长短的影响较大,当幼苗期条件不利于花芽分化时则受花期早晚的影响较大。四、第一花序节次的高低随育苗环境条件而变。在一年中有二次高低节次变化(包括温室栽培在内)即春秋低冬夏高。杂种也表现相似的趋势。节次的高低似乎主要决定于光照强度和日温差大小。五、第一花序节次的高低和品种成熟期的早晚并无一定的相关,所以这方面的传统说法是需要修正的。六、果实发育所需时期的长短与果实最后达到的大小无明显相关。果实发育期的长短主要决定于幼果期的发育速度,而幼果期的长短主要决定于气温,平均温度在20℃以上时显著较在15℃左右时为速。果实发育所需积温约在800℃左右早熟品种较少晚熟品种较多。七、继续选择早熟单株早期果实能使平均单果重逐渐减轻。八、在控制结实花序数的情况下平均单株产量主要决定于平均单果重而与平均单株结果数无明显相关。九、从6月下旬到8月的产果期内分期产量的分布呈单峰曲线,如以十天为一期则一般品种都在第三第四期达产量的最高峰。一般前三期的产量已达总产量的70~90%,故为有效利用土地起见番茄从开始采果起经30~40天即可拔株。十、杂种第一代在早熟性丰产性和早期产量方面一般都优于亲本品种。从利用杂种第一代获得早熟丰产系统来讲「比(?)」「矮红金」「波达里斯可夫」等都是较优良的亲本。

Considering the nucleus as an axial asymmetric quantum mechanical system, we have discussed the rotational spectra of even-even nuclei under the adiabatic approximation. The following results are obtained.1. From the detailed analysis of low-lying energy levels of ten nuclei, rotational spectra of axial asymmetric nuclei definitely exist. The theoretical values of energy levels agree with experimental results very well. (See Fig. 1)2. We have obtained the three principal moments of inertia, (?)1, (?)2 and (?)B, of ten nuclei (Os190, Os186, W183, Er168, Er166, Dy150, Gd156, Gd154, Pu283, Pu240).3. The relation among the throe moments of inertia, as predicated in Eolir's model, is proved to be incorrect. According fo Bohr's theory, one should haveThereforeBut the values of (?)1, (?)2, and (?)0, deduced from experiments do not satisfy this relation. (See Fig. 3)

把原子核看作一非轴对称量子力学体系,在绝热近似下,考虑了其转动激发能谱。我们只讨论了偶偶核。计算及讨论表明: (1)原子核,特别是重核,肯定存在着非轴对称转动能谱,从我们仔细计算过的十个原子核能谱来看,理论值和实验值符合得很好,(见图1),大多数与实验值的偏离≤1%。 (2)我们第一次求得了原子核(Os~(190),Os~(186),W~(132),E~(166),E~(165),Dy~(160),Gd~(156),Gd~(154),Pu~(238)和Pu~(240))的三个主转动惯量θ_1,θ_2和θ_3。(表1). (3)原子核转动惯量之间并无A.Bohr理论所指出的关系。按照Bohr理论, (θ_1/θ_3)~(1/2)-(θ_2/θ_3)~(1/2)=1 但我们从实验求得的θ_1,θ_2和θ_3并不满足上述关系式(见图3)。
