    本文是应用塔巴罗夫斯基方程(以下简称塔氏方程)计算地面气压变化的一个尝试。作者计算了沿经纬线均匀分布的五十个点的塔氏方程十八项的数值。应用的例子是一个深的高空槽。 公式(3)的第一、二两项分别为风速散度(注一)及轨迹曲率的变化。由计算可以看出,在高空这两项的数值最大。而它们所引起的气压变化,在很大程度上为一部分其它项在低层的相反作用所补偿。这样的垂直方向的质量散度的分布造成了很强的垂直运动。其它项在高层则多相互抵消。 前两项,即散度与曲率在强烈的大气过程发展中的决定性的作用,还可以由以下两点得证明: 1.用温度绝热交化算出的垂直运动(图三)有只用散度项及曲率项的高空质量散度算出的垂直运动(图二)很符合。 2.在地面气压倾向乘以面积的总和△P。与在950-200毫巴整层中前两项的散度乘以相应面积的总和△P之间有密切的关系(图七) 其它因子对地面气压变化的供献尚取决於具体条件,不过数值均不甚大。 根据得到的关系求出三个计算地面气压变化的半经验公式[(4),(5),(6)]。

    1. In this study which has been carried on since 1949,attempts were made toanalyse factors involved in the outbreaks of stripe rust of wheat in North Chinawith a view of giving some clues for forcasting.Five periods of the developmentof an epidemic of the stripe rust in this region are recognized:(1) the infectionand divelopment period of the rust on wheat seedlings in the autumn,(2) the over-wintering period,(3) the over-springing period,(4) the development period in thelate spring,and (5) the over-summering period.For each of the above stated peri-ods,the degrees of the stipe rust development are described and the main factorseffecting the development are analysed. 2. In the autumn,if field conditions were favorable for infection,the earlier ??the date of sowing,generally the heavier the wheat crops would be rusted.Therewere little or no stripe rust developed when the date of sowing wes later than thelast part of September although the condition might be varied appreciably withdifferent localities.Besides temperature,the period of high concentration of air-bornespores was the most important factor determining the disease severity in the earlysown wheat fields. 3. The stripe rust organism was capable of over-wintering in the form of dormant mycelium within infected leaves under the weather conditions of North Chinaplain.Heavy infection of wheat seedlings was the prerequisite of over-wintering,which was also influenced by micro-environmental conditions such as air temperat-ure,soil moisture and protection from wind.Air temperature was probably the mostessential factor. 4. The dry weather and the low moisture contents in the soil in the earlyspring were unfavorable to the development of the rust.Under these conditions,the over-wintering rust might be completely killed off or much lessened,while hig-her soil humidity usually favored the overspringing of the rust organism.Furtherdevelopment of the disease appeared to depend on the amount and frequency ofprecipitation.However,in flooded areas where the soil moisture was excessivelyhigh,epidemics might occur under dry weather. 5. The over-wintering inoculum was most important for local epidemics in spring,although long distance air-borne spore might also have some influence on the rustdevelopment in the later part of the wheat growing season. 6. Uredospores of stripe rust were not capable of over-summering on volunteerwheats in North China plain.Stripe rust collections from Elymus chinense andAgropyron spp.were capable to infect certain wheat varietes when inoculated arti-ficially,but under natural conditions these grasses appeared to play little part inthe aestivation of this rust in the vast wheat growing areas of North China.Theresults of spore-trapping indicated that Chang-Chia-Kow region and certain partsof inner Mongolia where spring wheats mature as late as the end of August weremost probably the reservoir of over-summering fungus which serve as the mainsource of autumnal infection. 7. Since there are great diversity of types of farming in North China,i.e.,(1)the dry land,(2) the well and river-irrigated land,(3) the low land and river-irrigated land of the mid-part of Shansi Province,and (4) the autumn floodedland,and as the environmental factors effecting the first four stages of stripe rustdevelopment were varied,consequently,the rust development in each type of landwas obviously different from others.The disease struck most severely in the wellor river-irrigated and the autumn-flooded lands. 8. Based on the foregoing results,the writers suggest that by means of timelyobservations and inspections on the stripe rust development during autumn and onthe amounts of the Survival after over-wintering and over-springing along with theweather forecasting data,it is possible to make fairly accurate forecast of the striperust epidemics in North China.

    1.华北区小麦条銹病主要的流行区域是井水地、渠澆地及水涝地。2.在秋季田間环境对侵染有利的情况下,小麦播种愈早的發病愈重。播种期晚于一定期限(各地不同,一般是9月下旬)發病就很輕或根本不發病。除温度外,空中孢子在秋季集中时期是决定早播病重的最重要原因。3.条銹菌可在华北北部平原的一般气候条件下以菌絲越冬。越冬的条件有二:首先是麦苗發病严重;其次是小气象适合。后者包括温度、土壤湿度与遮蔽物的有無等,其中起主导作用的是温度。4.春季的土壤湿度愈高,对条锈菌的“越春”愈有利。锈菌越春以后的流行一般是决定于雨水的多寡。但土壤湿度过大时(水涝地),也可以不依賴雨水多寡而在小区域內流行。5.春季菌源是多元的,但本地越冬菌起决定性作用,外地吹来的孢子只在后期起輔助作用。地面發病的严重程度和时期与空中孢子發現日期及濃度成正相关。6.条锈菌不能在华北平原的自生麦上和用抱子形态越夏,禾本科杂草中碱草及綠鬚鵝冠草锈菌用人工接种,虽可以發生枯斑反应或长出少数条锈病斑,但在分类上与小麦条銹菌不同,在大面积上不起越夏桥梁作用。根据秋季空中孢子捕捉和地面調查結??果,北方張家口专区壩土及內蒙古平地泉行政区等晚熟春麦区作为小麦条銹菌越夏菌源...

    Более систематическй иэучены петрографические типы и свойства фушуньских углей с точки эрения углепетрографии. наряду с этим, выбрали раэные петрографические типы и витрены каждой шахты и сделалн характеристику их химических и технологических свойств. установлено, что угли фушуньского месторождения макроскопически в основHом сложены иэ блестящих и слоисто-блестящих углей, а микроскопически в них витрен и кларен эанимают более 90%, нсключение лишь в пятом пласте, который несколько отличается большим содержанием дюрена. Свойства углей тесно свяэаны с их петрографическими типами, в случае этого месторождения особенности витрениэированных веществ играют решающую роль в свойствах углей всего месторождения. Также покаэано, что добавление определенного соотношения янтаря к длиннопламенным и гаэовым углям эападной части этого месторождения поэволяет повысить их спекаемость. угли этого месторождения принадлежат к малометаморфиэованным каменным углям. Свойства их эакономерно иэменяются по простиранию от востока на эапад, видимо, иэменение свойств, в частности спекаемости, главным обраэом обусловлено степенью метаморфиэма.

    從煤岩學觀點對撫順煤田煤的岩相類型和性質進行了較系統的研究,並選擇不同煤岩類型和各礦井的鏡煤進行了化學和工藝性質的鑑定。本煤田煤宏觀上主要由輝煤及輝層狀煤組成,而微觀上則由90%以上的鏡煤和亮煤組成,僅第五分層稍例外,暗煤和絲炭較多。煤的性質與其岩相類型有密切聯系,在本煤田中,鏡煤質的特性對整個煤田煤的性質起决定性作用。證實了本煤田西部的長熖煤及氣煤添加一定此例的琥珀可提高其粘結性。本煤田煤屬低變質程度的煙煤,煤質沿走向由東向西發生有規律的變化,可以認為這種變化,特别是粘結性的變化,主要决定於變質程度的不同。
