Abstract: The present disclosure relates to a content generation method, a readable medium and an electronic device. The content generation method includes: displaying a content generation page, where the content generation page is used to generate textual content required for live-streaming; and displaying, in response to target information of a target object that is entered in the content generation page, live-streaming textual content that is for the target object and generated based on the target information, in which the live-streaming textual content is used to introduce the target object in a live-streaming manner.

Abstract: The present invention provides use of a pure iron-based matrix for preparing a diamond bit and a method for preparing a diamond bit. The present invention uses the diamond bits prepared from the pure iron-based matrix made of iron powder with an average particle size of 1-25 ?m in different scenarios. In the present invention, the iron powder with the average particle size of 1-25 ?m is used to shorten a movement distance of iron ions, which greatly enhances activity of the iron powder, is beneficial to improving hardness and strength of the diamond bit, and can increase a holding power and wear resistance to the diamond. In addition, in the present invention, a pressure of hot press sintering of the diamond bit is controlled at 700-860° C., and a temperature of pressureless sintering is controlled at 900-960° C.

Abstract: The invention provides a safety injector needle. The safety injector needle includes a needle seat, an injection needle axially fixedly connected to the needle seat, and a trigger protection assembly assembled on the needle seat, the needle seat includes an assembly part and a fixing part; the trigger protection assembly includes a case, a trigger mechanism and an elastic element; the case is arranged in a hollow tube shape; the trigger mechanism includes a first trigger mechanism and a second trigger mechanism. The first trigger mechanism can slide along the extension direction of the case under the action of the elastic element.; the second trigger mechanism can slide along the extension direction of the needle seat under the action of the elastic element, so that the injection needle is completely contained between the trigger mechanism and the needle seat after the safety injector needle is used.

Abstract: An anomaly detection method for virtual machines in a cloud system, in which an HsMM is trained by searching the state information of the normal virtual machines in the cloud system, and a corresponding algorithm is designed to detect and calculate the probabilistic logarithm probability and the Mahalanobis distance of the dynamic changing behaviors of the resources in the cloud system when each virtual machine is online. If the Mahalanobis distance value of an online virtual machine is detected being higher than the preset threshold value of the cloud system, it is suggested that the virtual machine is operating anomalously.

If the Mahalanobis distance value of an online virtual machine is detected being higher than the preset threshold value of the cloud system, it is suggested that the virtual machine is operating anomalously. Moreover, an anomaly detection and treatment system in the cloud system will start to detect and treat the anomaly of the virtual machine.
