Abstract: A method of preparation of a cardo polyetherketone structural foam material, including the following steps: 1) performing a mould pressing on a cardo polyetherketone resin by a high-temperature vulcanizing machine to prepare a foaming billet; 2) placing the foaming billet in a foaming cavity of a mould-pressing machine, performing a penetration and a swelling by introducing a supercritical fluid to achieve diffusion equilibrium, forming a polymer-supercritical fluid homogeneous solution, and 3) making the polymer-supercritical fluid homogeneous solution supersaturated through a sudden release of the inner pressure of the system, thereby inducing nucleation and foaming, and finally forming a structural foam having a closed pore structure with a uniform pore size and an adjustable pore density. The production process of the present invention is clean, environmentally friendly, and has relatively high efficiency. The obtained structural foam has good mechanical properties.

Abstract: The present disclosure provides a rice planthopper-sensitivity gene BGIOSGA015651 and the use thereof. The applicant found a gene BGIOSGA015651 for regulating rice planthopper-resistance by studying on rice varieties BG1222 and TN1. The gene expression level of BGIOSGA015651 in the insect-resistant variety is hundreds of times or more different from that of the insect-susceptible variety. The expression of this gene can be reduced or knocked out by molecular breeding methods or genetic engineering methods, resulting in that the insect-susceptible plant can obtain high insect-resistance. The resistance level of the insect-susceptible rice variety TN1 is of level 9 before knock-out, and the resistance level thereof is significantly increased to level 0-1 after the rice planthopper-sensitivity gene BGIOSGA015651 is knocked out.

Abstract: An apparatus for measuring gravity acceleration of a drilling tool comprises sensors and a measurement circuit. The sensor comprises a three-axis gravity accelerometer, a reference measurement sensor and a temperature sensor. The three-axis gravity accelerometer measures acceleration component signals in three mutually orthogonal directions, and the reference measurement sensor generates a signal that varies with rotation and is not affected by vibration or shock to serve as a reference signal. The temperature sensor measures the temperature in the apparatus to compensate the temperature effect of the gravity accelerometers. The measurement circuit acquires output signals of the sensors and performs cross-correlation processing on the accelerometer components using the reference signal to extract gravity acceleration signals so as to eliminate centrifugal acceleration, vibration, shock and other interferences generated by rotation.
