Through static simulation in laboratory under artificial control, sludge degradation model and its effects caused by pH value trend, organism concentration, deposition time and temperature were studied.
This experiments were performed with potted planting, used“soybean north 9395”as materials, which was sensitive to B. Using artificial control situations of adumbral net and artificial climate box and chamber rainproof and air-condition and so on.
30% loss of timber volume was defined as the second level of control threshold, with an insect density of 21.93 heads/cm 2. For this insect population density, artificial migration of natural enemies should be used, with combination of artificial control methods.
Many kinds of sugarcane borer in the sugarcane planting areas of Leizhou Peninsula, the time of happening lasted very long, it can take the whole year in replacing to harm and heavy losses caused, the controlling countermeasure is the based on agricultural control, and take some chemical control to protect the seedling, biological control in the late stage and give artificial control, this measure has economy, safety and effective.
This paper discussed the application of TXJKⅢ hump automotive control system on the automotive and intelligent control of marshalling station. It focused on four aspects: artificial control automatization, system internet intelligentization, database management intelligentization and system compel process intelligentization.
In this paper the serial port communication by two slices of 8031 microprocessor is used to control signal to send and receive, the guard-dog is employed to implement the artificial control for areomodel, and the phenomenon of original system deadlocking and so on are overcome.
These characteristics of plants, among others, and the limitations of artificial control measures permit the maintenance of subeconomic levels of pests in agricultural crop areas.
This article discusses technical aspects of the calibration of leak detectors by using a series of artificial control flows.
In this article, recent progress in several aspects of puberty in teleosts is reviewed; namely, pubertal changes in brain-pituitary-gonad axis, factors controlling the timing of the onset of puberty, and artificial control of puberty.
The decline has followed artificial control of the water level in the lake.
Artificial control of cytoplasmic pH and its bearing on cytoplasmic streaming, electrogenesis and excitability of characeae cell
