The present invention discloses a method of three-dimensional optimization design for an asymmetric cusp magnetic field in an MCZ single crystal furnace. An optimization design for structural parameters of the magnetic field comprises first establishing a three-dimensional magnetic model by using an Ansys numerical analysis software; and varying parameters of the model, determining the span between the upper and lower parts of coils, the number of transverse turns of coils and the thickness of the shield based on a set magnetic induction intensity of the magnetic field, and determining the numbers of longitudinal layers of coils in the upper and lower parts of the magnetic field. An optimization design for specification parameters of the coils of the magnetic field comprises first determining a relationship between heat and specification parameters of the coils, determining a relationship between heat transfer of the coils at the copper pipe walls and the specification parameters of the coils, analyzing the heat absorbed by cooling water, establishing an optimization model of a system, and optimizing the specification parameters of the coils of the magnetic field by using the Ansys software. According the method of the present invention, the influence of the structural variation of the magnetic field on the variation of distribution and intensity of the magnetic field is intuitively revealed in three-dimension in view of all aspects, thereby reducing develop period and experiment cost on the cusp magnetic field, and increasing the efficiency of generating magnetic induction intensity by the magnetic field.

The invention provides a method for raising a green plant bug. The method comprises the steps of raising a newly-hatched green plant bug instar larvae by adopting corn as feed, and then feeding the green plant bug by utilizing green bean pods after the instar larvae is feathered. The green plant bug instar larvae is fed by the corn and then the green plant bug adult is fed by utilizing the green bean pods, so that the survival rate of the green plant bug instar larvae is high, the developmental duration is shortened, the weight is increased, the service life of the green plant bug adult can be prolonged, and the fertility of the female green plant bug is improved.

In a rotation angle detection apparatus, a signal detected by a magnetoresistive element is digitalized before being subjected to subtraction of the optimum correction parameter therefrom in a subtractor, the optimum correction parameter being stored in advance in a memory. Note that during the initial transmission at the time of activation, the data size “n” of a detection target obtained by a CPU from a control device is transferred to the memory, so that the optimum correction parameter for the data size of the detection target is selected. With the above, the detection unit can relatively readily cope with a request for enlargement or the like of a through hole size made by a machine side, and detection accuracy is not deteriorated and an error in absolute position processing is reduced when the curvature of the detection target is changed.

The invention discloses a German cockroach feeding cage and a German cockroach breeding method, and relates to the technical field of insect breeding, wherein the breeding cage comprises a feeding cage main body, a feeding culture dish and a watering assembly; the feeding cage main body is further provided with one or more insect habitat boxes, and the main body of the feeding cage comprises a cage door, and an insect collecting cylinder channel is embedded in the cage door. The German cockroach breeding cage is suitable for large-scale breeding of German cockroaches in a laboratory, and the feeding and drinking is facilitated; the device can prevent the German cockroaches from escaping to a certain extent; the breeding method comprises the steps of work preparation-migration-watering-feeding-cleaning-trapping, thereby meeting the growth and development requirements of the German cockroaches, and achieving the large-scale feeding of the German cockroaches in a laboratory; the development period of the German cockroaches can be obviously shortened by optimizing the feeding conditions, the hatching rate of the egg sheaths is high, the survival rate is high, the insect body consistency is good, and the development is excellent.

A synchronized linking system between engineering analysis programs includes: a global variable extracting unit for extracting global variables defined in source codes of programs; a memory management unit for creating a database to search for global variables according to variable name and storing the database in the shared memory; a translation unit for changing an original source code to allocate storage space of the shared memory, and then creating an execution file for each program, after removing a global variable declaration area of the source codes; and a code executing unit for executing the execution files created by the translation unit and progressing over time at synchronized time intervals, and storing and restoring the storage space of the shared memory that determines status of each program on a physical memory.

The invention relates to the field of agricultural pest biological control, and discloses a tung tree inchworm black egg bee breeding method which comprises the steps of tung tree inchworm breeding, tung tree inchworm black egg bee parasitism and tung tree inchworm black egg bee batch breeding. Enabling the tung tree inchworm black-egg bees to parasitize in tung tree inchworm eggs, and performing batch breeding of the tung tree inchworm black-egg bees after eclosion of the tung tree inchworm black-egg bees. According to the method, the tung oil tree inchworm eggs are used for breeding the tung oil tree inchworm black egg bees on a large scale, when the tung oil tree inchworm pests occur, the tung oil tree inchworm black egg bees are released to forest areas where the tung oil tree inchworm pests occur, and green prevention and control are achieved.

The invention relates to the field of biological prevention and control of agricultural pests, and discloses a method for breeding tung tree inchworm microdiplodia variabilis, which comprises the steps of breeding tung tree inchworm, parasitizing tung tree inchworm microdiplodia variabilis and breeding tung tree inchworm microdiplodia variabilis in batches. The method comprises the following steps of: parasitizing the tung tree inchworm diplodia variabilis on the body surfaces of larvae of the tung tree inchworm, and carrying out batch breeding on the tung tree inchworm diplodia variabilis after the tung tree inchworm diplodia variabilis parasitizes. According to the method, the tung oil tree inchworm larvae are used for large-scale breeding of the tung oil tree inchworm long-distance agaricus bisporus, when the tung oil tree inchworm larvae occur, the tung oil tree inchworm larvae are released to the forest area where the tung oil tree inchworm damage occurs, and green prevention and control are achieved.
