| 1 | Chill injury in the eggs of the migratory locust, Locusta migratoria (Orthoptera: Acrididae): the time-temperature relationship with high-temperature interruption显示文摘Mortality of the overwinteing egg of the migratory locust, Locusta migratoria L., was attributed to chill injury because of its occurrence weU above the egg's supercooling point. In this study, two parameters, upper limit of chill injury zone (ULCIZ) and sum of the injurious temperature (SIT), were used to examine the locust egg' s cold hardiness.The value of ULCIZ for the locust egg is 1.06 + 0.54℃, and the SIT is -329.7 (hour·degree). The superoxide dismutase (SOD) and catalase (CAT) activities changed dramatically after cold stress, indicating that oxygen and hydroxide free radicals are probably efficiently detoxified at low temperatures. It was suggested that the nature of chill in jury inlocust egg might be a complex of metabolic disorder and a non-proportional decrease in enzymatic reaction and transports, because the LDH activity at low temperature increased significantly and the ATPase activity decreased with prolonged duration of exposure to low temperatures. The results from high temperature interruption revealed that the high temperature intervals significantly increased the survival of locust eggs. | XIAO-HONGJING XIAN-HUIWANG LEKANG | 2005 | Insect Science2005，12，3： | 4 |
| 2 | Research and design of the main equipments and structure of Xiangjiaba shiplift显示文摘The type of pinion and rack vertical shiplifts has been developed in recent a couple of years in the construction of dams.But the design methods and methodologies have rarely been discussed in literature.The Xiangjiaba shiplift is the second shiplift of this type following the Three Gorges shiplift.Being aimed at the technological rationality of the design in synthetically considering security,economy and applicability,this paper presents the research results of some vital issues relating the design of the Xiangjiaba shiplift,including the determination of design water depth of ship chamber based on fluid numeral computation and physical model test,the optimum design of general layout of main equipments and the civil structure of the Xiangjiaba shiplift,the finite element method(FEM) analysis of stress,vibration modes and the buckling of ship chamber,antiseismic research and the design of structures and mechanisms of the shiplift and the optimum design of driving mechanisms.This research provides the theoretical basis for the design of the Xiangjiaba shiplift.The design principles and research methods are valuable for the design of the same type of shiplifts. | Liao Lekang Zhu Hong Zhang Rui | 2014 | Engineering Sciences2014，12，5： | 3 |

| 11 | The principle of minimization of the equivalent load for design of launching vertical shiplift显示文摘Launching vertical shiplift is a type of shiplifts which have the advantages in characteristics of dynamics and statics,safety and simplicity in operation. But their applications are limited as the scales of mechanical equipments are too large. This paper puts forward the principle of minimization of the equivalent load for the general layout design of launching vertical shiplifts,based on the analysis of the load probability of the main hoists and their key mechanical equipments. The principle aims at determining the optimal weight of counterweight so that the equivalent loads of the main hoists of shiplifts are minimized,and larger ships are permitted to pass through. The theory and method presented in this paper have been applied in the design of the first step and third step shiplifts of the Goupitan Hydro Power Station. This has resulted in the breakthrough of the design and manufacture of launching vertical shiplifts so that the ships with tonnage of 500 t can pass through hydro dams for this type of shiplifts,comparing with the largest launching shiplift in Yantan Hydro Power Station with the 250 t shiplift. | Liao Lekang | 2014 | Engineering Sciences2014，12，1： | 1 |
