中国智能手机Q3销量苹果跌至第六

赛诺数据显示,截止2018年9月,中国智能手机整体市场相比较去年依然呈缩减状态。9月中国智能手机市场容量3503万台,同比下降7.7%。 就第三季度数据而言,排名前五的手机厂商分别为vivo、OPPO、华为、荣耀和小米,苹果则跌至第六。其中,vivo销量2062万部,同比增长15%,市场份额为19.2%;OPPO销量2058万部,同比下滑4%,市场份额为19.1%;华为销量1711万部,同比增长32%,市场份额15.9%;荣耀销量1362万部,同比增长19%,市场份额12.7%;小米销量1261万部,同比增长1%,市场份额11.7%。 此外,不少厂商也在该季度出现销量同比严重下滑的现象。OPPO同比下滑4%,苹果下滑16%,魅族下滑53%,三星下滑39%,金立下滑82%。由于销量下滑,苹果市场份额则从第一季度和上半年的第二位滑落至第三季度的第六位。 值得注意的是,由于华为和荣耀是分开统计,如果两者销量相加,则华为+荣耀销量为3072万台,市场份额为28.6%,超过vivo位列行业第一。

e2v emerald 67 megapixel global shutter image sensor

Teledyne e2v (Chelmsford, UK) recently announced its Emerald 67 megapixel, the newest member of its Emerald CMOS image sensor family. The new sensor features a high resolution with a small global shutter pixel (2.5µm). Emerald 67M provides ultra-low noise performance and only 2.8e- of readout noise. The sensor is highly sensitive with 70% QE, enabling precise defect and particle identification. The new sensor is compatible with 59 x 59mm² camera platforms and has optical and package centers that are fully aligned for easy integration. It has an APS-C optical format, up to 72 sub LVDS outputs and 8/10/12 bit conversion modes, all within a reliable ceramic µPGA package. teledyne e2v

Dual Native ISO

EOS HD Two dedicated circuits are provided for each pixel. a circuit for low ISO, another circuit for high ISO. It switches the circuit, instead of just applying a gain.  This is used in Sony and  Aptina sensors. sensorworld sony patent US 20170148832 abstract: Imaging sensors, imaging apparatuses, and methods of driving an image sensor are provided. An image sensor can include a semiconductor substrate with a photoelectric conversion element and a charge-conversion element. The sensor can further include a capacitance switch. A charge accumulation element is located adjacent the photoelectric conversion element. At least a portion of the charge accumulation element overlaps a charge accumulation region of the photoelectric conversion element. The charge accumulation element is selectively connected to the charge-voltage conversion element by the capacitance switch. In order to increase the dynamic range of a pixel, it is desirable to incre...

習近平 人格分析

大陸一些媒體曾轉載了日本《鑽石周刊》網站的一篇關於習近平8個特徵的文章。習的8個特徵中包括 敢於打破陳規舊習、 掌控能力強、 最後由自己做決定、 敢於冒險、 行動無法預知等, 而這些特徵在這兩年多的中共高層博弈中屢屢體現,敢於對高層「開刀」就是體現之一。  習近平的決策心理分析  - 李智琦 從習近平的人格分析究之,其表面看似 草根、直率的性格卻也隱含了對權力的追求 ,但運籌帷幄的手段則是「弱鳥先飛、滴水穿石」。習近平行事務實、耐心布局、講求集體分工、重視群眾反應的性格將體現在執政第一任期,除了旨在穩固執政班底之外,在重大的決策上將延續 過去的大方向,「胡規習隨」、甚至是「江規習隨」的現象將不令人意外。值得一提的是,習近平的政治敏感度是在  第一、二代元老間的氛圍之中培養出來的,依此衍生出對 世局的見解可能與前代的意識形態藕斷絲連。他雖不至於   固守舊時的冷戰思維,但想冀望他在執政初期大力地在黨  內外進行民主改革以及終止與美國在「超強」上的惡性競 爭恐怕是不切實際的; 2013年1月爆發的「南方周末事件」顯見中共高層對新聞箝制仍嚴。此外,在前日北韓飛   彈威脅期間,儘管美國的多次喊話以及美國國務卿凱瑞(John Kerry)的到訪,希望中國能壓制北韓,習近平卻仍 不為所動,反觀在聯合金磚四國與南方國家對抗已開發等   歐美國家的態勢漸露。在「 中國夢 」的前提下,經貿發展 與提升中國整體國力將是習近平的治國優先順序,「 趕歐超美 」還是主要目標。 boxun: 分析习近平性格特征:     1.粗暴、蛮横、强势、好功名,心胸狭窄,任人唯亲善于掩饰,表明他不可能主动进行社会转型,民主宪政,比较适应极权主义制度。     2. 朴实表明他注重目的和结果不注重过程,敢于违反法律,中国会全面流氓化。     3. 传统文化和中国宗教情节导致他不喜欢新的和西方文化,思想具有保守性,排斥基督教等西方文化。     4. 好色的性格,待他权力稳固,会使他放纵情欲、堕...

普洱生茶陳化的化學成份

普洱茶後發酵過程中的水浸出物、茶多酚、氨基酸、咖啡鹼、水溶 性碳水化合物、香氣成分、微量元素和茶多酚氧化聚合產物的變化及其在產品中的 含量,並對茶多酚中的沒食子酸、水化果膠、四種微量元素和茶多酚的氧化聚合產 物 普洱茶化學成分研究     普洱茶是雲南特有的地理標誌產品,以符合普洱茶產地環境條件的雲南大葉種 曬青茶為原料,按特定的加工工藝生產,具有獨特品質特徵的茶葉。普洱茶分為普 洱茶生茶和普洱茶熟茶兩大類;普洱茶生產是以符合普洱茶產地環境條件下生長的 雲南大葉種曬青茶為原料,經蒸壓成型等工藝製成的緊壓茶;外形色澤墨綠,香氣 清純持久、滋味濃厚回甘、湯色綠黃清亮,葉底肥厚黃綠,其品質特徵、化學成分 與大葉綠茶相似。 普洱熟茶是以符合普洱茶產地環境條件的雲南大葉種曬青茶為原料,經後發酵工藝 加工形成的散茶和緊壓茶;後發酵過程有自然緩慢後發酵和人工渥堆快速後發酵兩 種方式,自然緩慢後發酵現有經過長期貯存陳化;人工渥堆快速後發酵則在高溫、 高濕條件下進行;在後發酵過程中,由於微生物等多種因素的參與和作用下,在制 茶坯中原有的各類化學物質急劇的變化,形成了普洱熟茶特有的色澤紅褐,內質湯 色紅紅濃明亮、香氣獨特陳香、滋味醇厚回甘,葉底紅褐的品質特徵。 下屬就以普洱茶的水浸出物、茶多酚、氨基酸、咖啡鹼、水溶性碳水化合物、香氣 成分、微量元素和茶多酚氧化聚合產物八個方面進行綜述,以此抛磚引玉,為普洱 茶愛好者、關注者提供普洱茶熟茶化學成分的輪廓。   一 普洱熟茶中的水浸出物   茶葉中水浸出物是指能被熱水浸泡出的物質,主要包括水溶性糖、水溶性茶多酚 及其氧化物、咖啡鹼、游離氨基酸、水化果膠等,是茶湯的主要成味物質。水浸出 物含量的高低反映了茶葉中可溶性物質的多少,標誌著茶湯的厚薄、滋味的濃強程 度,從而在一定程度上反映了茶葉品質的優劣。故茶葉中的水浸出物含量通常作為 評定茶葉品質好壞的重要指標之一。據研究表明:水浸出物在普洱茶的渥堆發酵過 程和普洱茶的濕倉陳化處理過程中,其含量均呈下降趨勢,而在幹倉陳化過程中則 有增加趨勢。普洱熟茶的水浸出物含量一般在(35±3)%。  二 普洱熟茶中的茶多酚 茶多酚是茶葉中三十多種酚類物質的總稱,主要由兒茶素、黃酮類物質、花青素和 酚酸四大類物質組成,是茶葉中的重要物質,其...

MTR HK severe delay

on 16 Oct morning rush hours, an unprecedented four lines – the Island line, Tsuen Wan line, Kwun Tong line and Tseung Kwan O line – were hit by severe delays. The MTR called on commuters to use other forms of public transport after journey times were extended by 40 minutes on some of the routes. Speaking to the press on Tuesday morning after the initial announcement of the delays, MTR Corp operations director Adi Lau Tin-shing said the team had noticed the signalling failure at about 5.30am on Tuesday as it started to prepare services for the three lines. “As a result, the command [for] train speeds could not be passed to trains [on the] Kwun Tong, Tsuen Wan and Island lines,” he said. “Because of the safety first principle, [we could] only operate the service by manual operation with slow speeds.” Lau said the company could provide only 20 to 30 per cent of the services normally offered during peak hour, and called on other public transport operators to provide ...
