Bluetooth is wireless technology that connects all the devices present within short distances, with frequencies in the range of 2.4 GHz to 2.48 GHz. Bluetooth speakers can pair with other devices at 10-100 meters. Bluetooth 4.0 is also known as Bluetooth Smart. It provides high-speed and low-energy protocols. Bluetooth speakers are controlled wirelessly through smartphones, tablets, and smart wearables.

Coffee creamer is a cream substitute for milk or milk powder, which is used in coffee or tea extracts, chocolate beverages, and other food preparations. Coffee creamers are vastly available, as per consumers tastes and lactose tolerance abilities, in dairy and non-dairy versions. Dairy coffee creamers contain lactose, and non-dairy coffee creamers are lactose-free. In addition, they are low in calories, come in a variety of tastes, are plant-based, nutritious, and contain natural ingredients such as almond and soy.

Artificial furs or faux furs are textile fabrics that are designed to resemble animal furs in terms of appearance and warmth. They are known as pile fabrics and are made of polymeric fibers that are processed, dyed, and cut to match specific fur textures and colors.

Jelly candies, commonly known as gummies, are a type of confectionery made from gelatin, sweeteners, flavorings, and colorings. These candies have a chewy texture and come in various shapes, sizes, and flavors. The gelatin provides the characteristic elasticity and chewiness, while the sweeteners and flavorings give them their distinct taste.

Infectious disease diagnostics refers to the testing and identification of pathogens causing diseases. It involves various methods such as molecular, immunological, and microbiological techniques to detect infections, enabling timely treatment and preventing disease spread.

The Irish whiskey is the fastest-growing type of whiskey globally. Irish whiskey is considered one of the best spirits in the world. It is made from unmalted barley and distilled for three years after that. When distilled, it goes through a fermentation process where other enzymes help to digest and metabolize the alcohol. It is then triple-distilled for better taste and smoothness. Irish whiskey is known to mix well with other drinks and is smoother than other whiskeys.

Isopropyl alcohol is also known as isopropanol or 2-propanol. These alcohols are colorless, flammable organic compound with a pungent alcoholic odor. Moreover, these alcohols are used in a wide range of applications, including disinfectants, personal care products, pharmaceuticals, cosmetics, coatings, organic chemical preparation, electronics, food and beverages, and various other applications.

我国科创债市场历经多阶段政策优化，从 2015 年“双创债”的初步探索，到 2022 年交易所与银行间市场同步推出科创公司债和科创票据，2025 年政策支 持进一步加码，央行提出构建债券市场“科技板”，支持科技创新债券发行。5 月以来央行、证监会联合发布《关于支持发行科技创新债券有关事宜的公告》， 随后交易商协会、交易所迅速响应，也制定发布相关通知。我们将 5 月以来一系列支持科创债发行的政策称为新政。

一季度，GDP 价格缩减指数为 99.23，比 2024 年四季度回落 0.03 个百 分点，比 2024 年一季度提高 0.24 个百分点，连续 8 个季度低于 100，仍处于低位。一季度，第一产业增加值价格缩减指数为 98.76，比 2024 年一季度提高 2.30 个百分点；第二产业增加值价格缩减指数为 97.59，比 2024 年一季度回落 0.08 个百分点；第三产业增加值价格缩减指数为100.16，比 2024 年一季度提高 0.20 个百分点。

固态电池产业化面临工艺与成本的双重挑战。在产业链多方合力推进下，固态电池产业化近期取得长足进展，2027 年量产装车逐步成为产业共识，车企、电池厂有关产品密集发布。从现阶段全固态电芯样品的性能参数来看，固态电池要从实验室走 向量产线，技术上仍面临电芯大型化瓶颈，当前全固态电池样品单体电芯大小普遍在 20Ah 左右，距离 60Ah 及以上的车规级水准尚有差距。成本方面，除了高价原材料亟待降本之外，全固态电池的技术、工艺与设备面临调整革新，良率、效率均与成熟阶段的液态锂离子电池相距甚远，造成初期高昂的制造成本。
