High-frequency titration curves are discussed for various methods of experimental determination (the Q-meter, Z-meter and F-meter methods), using equivalent circuits for C-type and L-type titrating cells. It has been found that for the cases of L-type cell with Q-determination and C-type cell with Z- or F-determination, the quantity measured in the course of titration changes monotonously with .the increase of conductivity of the solution. In these cases, the high-frequency titration curve should be similar...

High-frequency titration curves are discussed for various methods of experimental determination (the Q-meter, Z-meter and F-meter methods), using equivalent circuits for C-type and L-type titrating cells. It has been found that for the cases of L-type cell with Q-determination and C-type cell with Z- or F-determination, the quantity measured in the course of titration changes monotonously with .the increase of conductivity of the solution. In these cases, the high-frequency titration curve should be similar in shape to that obtained in an ordinary conductometric titration. Two mistakes appearing in literature are here pointed out. (1) The equivalent parellel circuit and the equivalent series circuit for the C-type titrating cell do give the identical result for the value of the conductance of the solution which gives the maximum loss of high-frequency energy in the cell. (2) The appearance of a maximum high-frequency loss with increasing conduc- tance of the solution in the C-type cell is not the result of the Debye-Falkenhagen effect. The use of Pt wire electrodes in direct contact with solution for high-frequency titration is suggested. Satisfactory titration curves have been obtained with wire electrodes and a series capacitor to act as a C-type cell with much less shielding troubles.

1.對高頻滴定用的C式和L式滴定,Q表法,Z表法及F表法测定得到的滴定曲線,與溶液電導改變的關係,用等效電路的理論,作了全面的討論。除C式滴定Q表法測定,文獻中已有討論外,L式滴定Q表法測定時,和C式滴定Z表法和F表法測定時,滴定過程中測定的量都與溶液的電導值單調變化。 2.指出了文獻中的錯誤。C式滴定應用等效串聯電路與等效並聯電路計算的結果,是完全等同的。C式滴定的高頻電能損耗與溶液中電解質濃度的關係,與Debye-Falkenhagen效應無關。 3.提出了用鉑絲電極直接插入溶液的高頻滴定法。

European corn borer is cosmoplitan in distribution. It causes a considerable damage in Cheking province, especially in mountainous regions where corn being grown as a main crop. The present paper deals with the biological investigation of the corn borer and its proper control measures aganist the pest. The biological studies and field experiments were conducted at Chekiang Agricultural college, Hanchow during the year 1954-1955. The general morphology of the insect is well studied. The setal arrangement of the different instars of the larvae is illustrated in plates. This insect has four gerenations annually at Hanchow and overwinters in larval stage. The adults emerge at late May or early June. The females deposite their egg masses on the underside, and along the mid-rib of the leaf. There are about 48 eggs of a simple egg mass in average. The eggs mostly hatch at 9-11 a.m. and after hatching young larvae feed to some extent on the leaves, but soon bore into the leaf stems, the stalks, or the ears of the corn plants. The larvae move from one plant to another at their first three instars. The concentrated spray of 1% wettable DDT and 0.125% of wettable 666 suspension applied at a rate of 100 catties per mow in the 1st spray and 150 catties per mow in the 2nd spray, shows quite promising. The experiment of planting date of corn in relation to the infestation of European corn borer, shows that the most suitable date for planting corn is in the middle of July, in which infestation is lighter. The lighter infestation of late planting of corn is mainly due to the egg masses of European corn borer being heavily parasitized by Trichogramma evenescens Westw. since middle of July.

1.本試驗于1954—1955年在杭州華家浙江農学院農場進行。2.玉米螟一般形态作了簡單的記述。幼虫各分期形态的記載可供作区別令期的資料。3.玉米螟在杭州地区一年發生四代,以老熟幼虫在玉米稈越冬,越冬死亡率在5月中旬为最高达27.27%,成虫都在晚上活动,產卵在玉米叶背面主脈附近,离叶尖20—30厘米处最多,幼虫孵化在上午9—11时左右。4.春玉米可用1%可湿性DDT乳剂和0.125%r可湿性六六六噴射。第一次每畝用100市斤,第二次每畝用150市斤。在螟蛾盛發期施用效果顯著。5.玉米播种試驗說明在7月中旬播种的螟災比較輕,主要原因是由于7中旬以后玉米螟卵塊赤眼蜂的寄生率提高至97%以上。

Some types of glass made thermal conductivity cells for gas analysis were prepared by author, which were constructed with tungsten wire 0.013m. m. in diameter, as a hot wire. Some of their properties had been tested with the gaseous mixtures of hydrogen-nitrogen and of air-carbon dioxide. The prepared thermal conductivity cells may be used with a higher sensitivity, and insensitive to the variation in the rate of gasflow; and with a rapid response to the variation in the composition of gaseous sample during...

Some types of glass made thermal conductivity cells for gas analysis were prepared by author, which were constructed with tungsten wire 0.013m. m. in diameter, as a hot wire. Some of their properties had been tested with the gaseous mixtures of hydrogen-nitrogen and of air-carbon dioxide. The prepared thermal conductivity cells may be used with a higher sensitivity, and insensitive to the variation in the rate of gasflow; and with a rapid response to the variation in the composition of gaseous sample during the continuous analysis. The apparatus can be used suitably as a detector in gas chromatography.

作者用直徑爲0.013mm鎢絲爲熱絲、試制了幾種玻璃制氧體分析用導熱,並用■—■混合物和空氣—二氧化碳混合物試驗其性能。所製得的導熱具有較高的靈敏度,對氣體流速改變不靈敏。在連續分析中,對氣體組成改變的反應較快,可適於在氣相色層中用作测定器。
