Games can be divided into two dimensions: semantics dimension and syntactical dimension, from the perspective of semiotics. The semantic dimension sketches the appearance of reality, and the syntactical dimension sketches the mechanism of reality. The simulation games sketch the whole reality, while realistic games express realism based on sketching reality. Realistic games need to reconcile the differences between playfulness and realistic criticism. In this sense, the criticalness of realistic games is often questioned.

21世纪初始10年中末以来,逃杀游戏逐渐兴盛.这类游戏取消了划定玩家秩序的共同结构,玩家在以"缩圈"为方法的至高权力的排除性纳入下,不再是新自由主义式的,追求敌/我对抗的向外扩张的积极主体,而是在末世论的新保守主义世界观中,谋求最长苟活时间的向内收缩的赤裸生命.逃杀游戏是一座"游戏集中营",它打开了永恒的紧急状态.

在游戏史与社会史的互动脉络中考察游戏,可以窥见当代中国社会思想的流变.1980年代以来的中国游戏史,可被概括为本土的国家现代化脉络向全球资本逻辑的转变历程.中国游戏史的思想主题,1980年代是在国家现代化的框架下培育符合社会主义建设需要的时代新人;1990年代是在民族主义情绪对海外游戏的忧虑里询唤以爱国主义为底色的游戏玩家;2000年代是在"数字化生存"的浪漫想象与消费主义的碰撞中扩张互联网游戏的用户规模;2010年代的各类电竞游戏则以加速的方式打开了"游戏梦工厂"的大门.从中国游戏史的思想演变中可以发现,资本的逻辑不断驱逐游戏的逻辑,游戏世界正异化为网络资本平台.与此同时,玩家则由"知识"的学习者被"无产阶级化"、商品化与算法化,最终被询唤为以游戏消费者为表象的游戏/劳动者.中国当代游戏史表明,元宇宙只是平台逻辑的延伸,并非游戏史的未来.游戏产业需要探索市场与思想共存的辩证法,重拾游戏的精神与担当,在思想层级上实现有价值的文艺创造.

国风游戏是近十年才被提出的概念,但国风游戏的历史早已在隐形书写.国风游戏的历史书写包括1990年代的单机游戏、2000年代的MMORPG网游以及2010)年代的电竞游戏三个主要讨论面向.国风游戏的"国风"表述从来依附于游戏程序表面的文化层,通过对传统文化元素的视听调用虚构国家的在场,没有深入作为游戏逻辑内面构层的计算机层探索其应有的内涵.因此,国风游戏并未随其游戏形态的演进取得实质的发展,反而愈发陷入空洞化的表述危机,直至沦为后现代化的国风数据库.对于中国游戏业而言,当务之急是在计算机层构筑国风游戏的"国风"内涵,使之成为可被言说的确实对象.

21世纪流行的网络游戏是一种算学文本,属于文化层与计算机层的双重构造,分别对应着符号秩序与算法秩序.两种秩序互为表里,共同构筑网游世界.玩家通过操控数字元件进入网游世界,这种操控不是书写,而是游戏/劳动.玩家不是被可见的他者剥削,而是不自觉地自我剥削,并且享受剥削过程中的瘾性快感.算学文本仅具有工具理性,缺乏价值理性,其奉行0/1二进制的新自由主义,使玩家降维为单向度的人并走向精神孤立.未来中国的游戏产业,需要探索出超克算学文本固有逻辑的新型模式.

In order to study the affect of Projectile-barrel Contact/Impact on the muzzle vibration,establish a three-dimensional solid rifled barrel model,generate a modal neutral file with flexible body information of rifled barrel,create and solve a numerical simulation model of rigid-flexible coupling based on Projectile-barrel Contact/Impact in the software ADAMS,then find a method to improve the speed of solution,change the distance of front and rear bushing and solve the model,and put forward a method to reduce muzzle vibration.The simulation results reflect the feature of muzzle vibration,the change of the distance of the front and bear bushing has a few influences on the muzzle vibration.Simulation results show that the Projectile-barrel Contact/Impact has a few influences on the vertical velocity,displacement of muzzle vibration and horizontal velocity,and displacement of muzzle vibration.

A voxelization algorithm based on projection volume and octree is proposed.The projection volume of polygonal meshes on a voxel is used as a judging rule to decide its state:inside the body,outside the body.The calculation of the projection volume on a voxel is simplified by only considering the polygonal meshes that satisfy these two conditions:first,the projection area of the polygonal mesh intersects with the projection area of the voxel;second,the polygonal mesh locates on top of the voxel.A voxel in the octree structure is encoded with a "pedigree",which denotes its position in the octree and can be used for neighbor voxels finding.In this way,an area of inside voxels can be decided exclusively based on 6-neighborhood relationship as soon as an inside voxel is found.By checking the status of all voxels in an octree,all inside voxels can be found.The tests on some polygonal mesh models show that this algorithm is accurate and efficient,thus can be applied in GIS,geosciences modeling,CAD and other volume graphics related fields.

Through carry on trouble diagnosing and vibration analysis to the same sets of motor appear trouble successively,and to the trouble similar to the vibration form,this text adopts different diagnosis means to distinguish and distinguish separately,diagnose the weak foundation,electric trouble,rolling bearing damage three trouble that this motor appears finally,summarizes three common vibration characteristic of trouble and diagnose analytical method and skill.
