  product
In this paper we present an explicit formula for the twistors in the form of an infinite product of the universalR matrix ofUq(g).
      
These are analogous to "fusion rules" in tensor product decomposition and their derivation obtains from an analysis of theR-matrix.
      
In general, such a tensor product is no longer irreducible.
      
A fundamental question is how the irreducible components are embedded in the tensor product.
      
A special component of the tensor product is the so-called Cartan component Vλ+μ which is the component with maximal highest weight.

1. The albino mice were used for this study. The Golgi apparatus in the cells of the epididymis and the vas deferens of normal, starved, and refed animals were studied.2. The amount of the Golgi elements can be maintained by feeding, not only by the sex hormone.3. The Golgi apparatus may be regarded as a product of food assimilation, not a definite cell organ.4. It is suggested that the Golgi apparatus has similar organ with that of mitochondria and secretion granules, but with different quantity of lipoids....

(1)本研究以白鼠为材料,就常态白鼠绝食及再餵之白鼠观察其副睾丸及输精管上皮细胞内之高基體。查得在绝食期内副睾上皮细胞之高基體逐渐減少,由网状體变为颗粒,先集于前端後卽散开,至三十六小时高基體绝少,再餵後復有颗粒出现於前端。 (2)输精管上皮细胞内高基體原作线状,列於细胞前部。绝食十三时後,变为颗粒。俟三十六小时後再餵,卽有许多小粒在细胞前端边缘或卽係高基體 (3)由此结果可知高基體之多寡,既视绝食与否而定,或可谓为食物同化之产物,非固定之细胞器官也。 (4)高基體之起源或与粒线體,及分泌粒同,但其所含类脂質之量不同。

This is a preliminary report of the application of several methods in the making of bamboo pulp. The two-stage soda process and the two-stage sulfate process were first tested. It was found that the pulp obtained by the second process can be better bleached than that by the first process. In order to im-prove the quality of the pulp, the three-stage sulfate process was then applied. It consists of three steps, namely, cooking in water under slight pressure (115℃) for about one hour, digesting in a solution of...

This is a preliminary report of the application of several methods in the making of bamboo pulp. The two-stage soda process and the two-stage sulfate process were first tested. It was found that the pulp obtained by the second process can be better bleached than that by the first process. In order to im-prove the quality of the pulp, the three-stage sulfate process was then applied. It consists of three steps, namely, cooking in water under slight pressure (115℃) for about one hour, digesting in a solution of one percent of the cook-ing reagent (HaOH:Na2S=2:l) at 120℃ for two hours, and finally digesting in a 5% solution of the reagent for three hours. This 3-stage method gave a product which is satisfactorily white and was found equally applicable to sev-eral kinds of bamboo used.

本文系将数量制粕法应用於竹材纸粕之初步研究报告,试以二级碱法及二级硫酸盐法蒸解老竹,发现后者竟较前者更宜於竹材,所得硫酸盐竹粕,经漂白后色泽较碱粕为佳,再试以三级硫酸盐法,先以水於微压下(115℃)蒸煮一小时,次於120℃时以1%蒸解剂(NaOH:Na_2S=2:1)稀溶液预行蒸解两小时,最后以5%蒸解剂溶液蒸解三小时,结果可得洁白之纸粕,对於所用数量竹料均极相宜.第三级蒸解之最宜情况,经试验结果,以在160℃时用5%蒸解剂溶液(NaOH:Na_2S=2:1)蒸解3(1/2)小时之成绩为最佳,所得纸粕色泽既白,且漂剂消耗量亦低.作者曾将竹材皮层与心材剥离,分别以三级硫酸盐法蒸解,证明两者所得纸粕,就色泽及漂剂消耗量而言,大致相同,指示前人理论,谓老竹皮层中含有高分子胶质,纸粕不易漂白,似属不确.本试验仅用三种不同地区所产之竹为原料,故三级硫酸盐法是否适用於所有国产竹材,及其最宜蒸解情观是否完全相同,犹待於将来之研究.

Von Knorre first suggested the use of benzidine and o-tolidine for the determination of tungsten. With the latter reagent, he succeeded also in separat- ing tungstate from phosphate. Later on, o-dianisidine and vanillylidene benzidine have been proposed as precipitants for tungstate. The optimum pH ranges for the quantitative precipitation of tungstate by means of these precipitants and tetraminodiphenyl, which have not yet been found in the literature, are: benzidine pH: 2.0-5.5 o-tolidine 2.9-4.7 o-dianisidine...

The optimum pH ranges for the quantitative precipitation of tungstate by means of these precipitants and tetraminodiphenyl, which have not yet been found in the literature, are: benzidine pH: 2.0-5.5 o-tolidine 2.9-4.7 o-dianisidine 2.0-4.1 vanillylidene benzidine 1.7-3.9 tetraminodiphenyl 1.7-4.8 The effect of introducing various groups into the benzidine molecule upon the tungsten precipitating property is not profound. The relation between quantitative precipitation of tungstate with benzidine and the product of concentrations of both constituents before precipitation Was studied. It is found that quantitative precipitation of tungstate ions Can be realized only when the product of concentrations of reactants before precipitation is equal to or greater than 0.8 × 10~(-5), and the moles of benzidine added must be at least equal to that of tungstate. The gravimetlic determination of tungsten by means of o-tolidine may be applied to samples containing as low as 10 mg of rungsten trioxide in 200 ml solution, if an absolute error of 0. 5 mg can be tolelxted. For larger quantities of tungsten present in sample, the absolute errors amount to only 0.1-0.2 mg. Tetraminodiphenyl may be used as a tungsten precipitant, but no advantage over benzidine Wan found in our present studies.

1.用二胺聯苯及其數種衍生物沉澱鎢酸根時,其適宜的pH範圍如下:[4,4′]二胺聯苯 pH:2.0-5.5[3,3′]二甲基[4,4′]二胺聯苯 2.9-4.7[3,3′]二甲氧基[4,4′]二胺聯苯 2.0-4.1[4]對胺聯苯氮甲烯[2]甲苯酚 1.7-3.9[3,4,3′,4′]四胺聯苯 1.7-4.8 2.用[4,4′]二胺聯苯作沉澱劑時,二胺聯苯和鎢酸根在沉澱前的濃度之乘積與後者沉澱完全與否的關係,曾加研究。 3.用[3,3′]二甲基[4,4′]二胺聯苯作沉澱劑時,能测定低至10毫克的三氧化鎢。
