The coventional methods usually used for testing the performance of surfaces are to measure the average surface and fluid temperatures and the convective heat flux in steady state, and then according to Newton's law of cooling to calculate the average heal transfer coefficient h by dividing the convective heat flux by the difference between the average surface and fluid temperatures. Evidently, using this method,the accuracy of the heat transfer coefficient h obtained is mainly dependent upon the measurement errors of the surface and fluid temperatures, and the effect of the temperature measurement errors on the result is especially serious for the high effective and compact heat exchanger surfaces. However, just for these surfaces, measurements of the average surface temperature would still be very difficult and, even if attempt is made, undoubtedly the result would remain inaccurate. It is because the temperature measuring devices which locate on fin surfaces that are typically very thin and are seperated by about 1.5 mm. from adjacent fins for measuring local temperatures of surfaces would themselves influence the temperature and velocity fields within the test core substantially. Possibly this is why the informations of the heat transfer characteristic of the compact heat exchanger surfaces are now mostly obtained by the methods which are not necessary to measure surface temperature. A number of these methods have been developed in which it is not necessary to measure surface temperature They can be classified into two groups,i.e. ,the steady state and the transient methods while every group includes many kinds of the methods, Their theoretical bass, characteristics and limitations are different from each other. Thus for obtaining accurate results it is necessary to select appropriate method and carefully ensure well defined testing conditions according to the characteristics of the test core and its measuring range. This paper attempts to make some general remarks on the methods for determining the performance,so as to poin tout their advantages and disadvantages as well as their limitations, in order that we might properly make use of these methods to determine the performance of compact heat exchanger surfaces and to see which of the experimental results of the different methods will stand the test.

通常用来测试换热面放热性能的常规方法是先在稳定态下测量其换热面和流体的平均温度以及换热率,然后按照牛顿冷却定律将换热率除以流体和换热面的平均温度差来计算其平均放热系数h。显然,用这种方法求得的放热系数h的准确度主要取决于换热面和流体的温度测量误差;而对高效,紧凑换热面来说,温度测量误差的影响尤为严重。可是恰恰对高效,紧凑换热面来说,平均壁温的测量是十分困难的,即使勉力而为,也难以获得准确结果。这是因为为了测量换热面各处温度而装在翅片面(很薄而且相邻两翅片间的距离又只有1.5mm左右)上的测温元件本身将显著影响试件芯子内的温度分布和速度分布。这就是目前紧凑式换热面的放热性能的资料大多是用各种不需测定壁温的方法来求得的原因。这种不需测定壁温来确定换热面性能的方法巳发展有很多种,它们可区分为两大类:稳定态法和瞬变态法;而每一类又包含很多种。它们的理论根据,特点和适用范围都互不相同。因此,要获得准确结果,就必须根据试件的特点和测量范围,来选用合适的方法并仔细地保证规定的试验条件。本文将对各种不需测定壁温来确定放热性能的方法作一综合评价,给出它们的优缺点和适用范围,以便正确使用这些方法来确定各种紧凑式换热面...

The Bacterial pusule, caused by Xanthomonas var. sojensis Heages, is one of the bacterial diseases in soybean. In 1980 we made a survey on 346 copies of this disease from various regions in Hubei province in the experimental farm of our Institute. We computed incidence of this disease and index of disease state, and observed every varieties which was intected in different degree. The preliminary result has been gained as follows.1)The 95% tested varieties has been infected this disease in different degree. Index of disease state is from 0-55.13%. The susceptible rate of plant is from 0-84.62%. There are 15 varieties was not infected this disease. It was 4.34% of all tested plants. There are 251 varieties, which are light or medium infected. It was 72.54% of total tested plants. There are 25 varieties, which was infected this disease seriously. It was 7.22% of total tested plants.2) In observed varieties, 00042, 00050, 00228 and 00340 varieties was not infected or lightly infeeted and productivity per plant was predominant over the close control variety. It is expected to apply directly in production as resistant variety to this disease or resistant germplasm resources of this disease.3) There is a correlation amoung infected degree, origin, seedcoat colour, period of growing, but it is not predominant. The substances of these appearances should be remaied continually to research.4) In Wuhan region of Hubei province, summer soybean blooms in July and August. During-this season, it is suitable for incidence and development of this disease. It was seriously effected regularly growing of soybean and decreased yield and quality.

大豆叶烧病(Xanthomonas phaseoli var. sojensis)是一种细菌性病害。据报导,美国,巴西、印度、苏联等国家均有此病发生,美同南部湿度大的地区发病尤为严重,我国东北、华北以及华中地区亦有此病发生,1980年湖北省大豆叶烧病十分严重,著者在本所试验场的观察研究结果,大豆开花前后(武汉地区7—8月)连续阴雨,低温寡照是此病害发展的适宜条件;叶烧病对大豆产量、品质均有较大影响;不同品种的感病程度有很大差异。这种差异与种皮色、原产地以及生育期有一定关系。通过品种资源的抗病性研究,将有可能为大豆生产和大豆育种工作提供抗病(叶烧病)种质资源。
