Mining Machinery Promoted by Cone Crusher One

政府强调新能源行业作为经济新增长点与国际战略高点,金融危机为新能源行业带来机遇。香港星公司已在建筑和交通节能方面取得成就,国内城镇建筑能耗占绿色温室气体排放的三分之一,城市空调系统能耗占整体建设能耗的50%,开发“零排放”计划将极大促进国家能源结构调整和工业结构优化。同时,复合电动汽车、电动轿车、电池汽车的研发正逐步推进,尽管在电池、充电和能量转换系统方面存在劣势,但仍具有巨大的商业潜力。

At present ,we government have seen the importance and developing trend in the new-energy industry .And the vice president Mr.Li have pointed that : the new energy promises the new potential economic growth point and also a new international strategy high point .An when the financial crisis have brought the new opportunity for the new energy industry .We should take the new-energy development as the major measure ,and the enterprises as the major target .And we should also fasten the energy renovation , extremely reduce the consumption to the natural resources ,and extremely reduce the waste pollution till we realize the “zero discharging”, which will definitely promote the adjustment of our national energy structure and even the industrial structure .

Hongxing also has achieved some achievement in the construction and transportation energy-saving .And now we country have 50 billion square meters of township building ,whose energy consumption have covered 1/3 of the whole green house release .While the energy-consumption of city air-conditioner system have covered 50% of the overall construction energy-consumption .And if we can start the “zero discharging ”plan in developed countries ,the market will become huge .At present ,the research and development of the compound motor car ,electric car ,battery car are under the way while we can firstly achieve the breakthrough in the compound car .Even though we have a weak advantage in the battery ,charging and energy transformation system ,it still exist huge business potential .

In 1990’s ,shanghai has experienced a lot in the development to the international trend .As the sand-stone Henan need are mainly from other places’ supply ,which have provided better development opportunity for nearby sand-stone enterprises of Zhejiang province ,particular the mining crushing enterprises .And with advanced technical equipment , large-scale operation and modernized management technology, Hongxing can continuously produce crusher, grinding mill and sand-making machine .With the continuous improvement ,Hongxing have produced more mining machineries like shaper machine ,mobile mobile crushing plant, MTW series trapezoid grinding mill ,JC series jaw crusher ,hydraulic cone crusher and so on. And all of these equipments have been widely applied in the field of national highway, railway construction .And Hongxing have contributed its contribution to the national construction and also received the common popularity.

As the professional manufacturer of complete sets of mining machinery, such as China cement mill,Secondary cone crusher,Symons cone crusher,Stone jaw crusher, Henan Hongxing is always doing the best in products and service.

在 Android 系统中,`PROMOTED_ONGOING` 是与进程优先级和任务调度相关的一个状态标识,通常用于描述某些具有较高重要性且需要持续运行的前台任务。该状态主要用于系统对应用进程进行资源管理和调度决策,确保关键任务获得更高的系统资源优先级。 ### 作用 `PROMOTED_ONGOING` 的核心作用是提升特定任务的优先级,使其更不容易被系统回收或降级。当一个任务或服务被标记为 `PROMOTED_ONGOING` 时,它会被视为正在进行的重要操作,从而影响系统的 OOM(Out Of Memory)调整策略。这种状态常见于需要保持活跃状态的任务,例如: - 长时间运行的前台服务 - 某些系统级操作(如备份、恢复等) - 与其他高优先级组件交互的关键任务 通过将任务标记为 `PROMOTED_ONGOING`,系统可以更好地判断哪些进程应当保留,避免因内存压力而被过早终止[^1]。 ### 使用场景 1. **前台服务**:当应用启动了一个前台服务(Foreground Service),系统可能会将其标记为 `PROMOTED_ONGOING`,以确保其不被轻易杀死,尤其是在资源紧张的情况下。 2. **系统关键任务**:一些系统组件在执行关键操作时会使用此状态,比如设备恢复出厂设置、OTA 升级过程中的数据迁移等。 3. **跨进程通信中的关键事务**:当某个任务正在等待来自另一个高优先级进程的结果时,系统可能将其提升为 `PROMOTED_ONGOING`,以防止其提前终止导致死锁或中断。 4. **Activity 启动过程中的中间状态**:在 Activity 启动过程中,如果涉及到多个组件的协同工作,系统可能会临时将某些进程标记为 `PROMOTED_ONGOING`,以保障启动流程顺利完成[^1]。 ### 示例代码片段 以下是一个简化的示例,展示如何在系统源码中检查一个任务是否被标记为 `PROMOTED_ONGOING`: ```java if ((taskInfo.flags & ActivityManager.LOCK_TASK_FLAG_PROMOTED_ONGOING) != 0) { // 任务已被标记为 PROMOTED_ONGOING Slog.d(TAG, "Task is promoted as ongoing"); } ``` 此类标志位通常由系统框架根据当前任务状态自动设置,并参与 OOM 调整策略的计算。 ### 进程优先级的影响 当进程被标记为 `PROMOTED_ONGOING` 时,它的 `oom_adj` 值会被调整为更低(即更高优先级),这使得它在内存不足时更不容易被 Low Memory Killer(LMK)机制杀死。这种调整机制有助于维持用户体验,特别是在执行关键操作期间[^1]。 ---
