制劑實驗室，需要用到萬分之一天平、百分之一天平，有必要設置一個單獨的隔間嗎？做的液體制劑，我考慮稱量定重的時候，直接在實驗室操作台上操作，十萬分之一天平可以設置個稱量間，因爲靈敏度的問題，但是萬分之一和百分之天平有沒有必要？

天平室一般布局是緩沖間進去以後由軌道門隔斷爲幾個小房間；高精度天平（百萬分之一）要求獨立，防止氣流、人流、震動幹擾。
      
十萬與萬分之一天平可以擺放到一起。
      
不建議將天平室放置在實驗室現場（一是因爲溫濕度不好控制，其次就是會受到實驗室氣流、人流過多幹擾，第三就是實驗台沒有緩震裝置天平會受震動的影響波動較大）

在制劑研發實驗室中，天平的放置是否需單獨設置隔間，主要取決于天平的精度要求、實驗室環境以及實驗操作的規範性。以下是針對萬分之一和百分之一天平的分析：
      

      
1. **精度要求**：万分之一和百分之一天平虽然精度较高，但相较于十万分之一及更高精度的天平，其对环境的要求可能相对较低。然而，为了确保测量的准确性和稳定性，仍需避免温度波动、湿度变化、气流干扰、振动和静电等因素对天平的影响。
      

      
2. **实验室环境**：如果实验室整体环境较为稳定，且能够有效控制温湿度、减少气流和振动等干扰因素，那么万分之一和百分之一天平可以直接放置在实验室的操作台上进行操作。但如果实验室环境存在较多不确定因素，如温湿度波动较大、有腐蚀性气体或强气流等，则建议为这些天平设置单独的称量间，以提供更为稳定的工作环境。
      

      
3. **操作规范**：无论天平是否放置在单独的隔间内，都应遵循相关的操作规范，如预热天平、保持天平水平、定期校准和维护等，以确保天平的准确性和可靠性。
      

      
綜上所述，對于制劑研發實驗室中的萬分之一和百分之一天平，是否需要單獨設置隔間應根據實驗室的具體環境和天平的使用要求來決定。如果實驗室環境穩定且符合天平的使用要求，可以直接在操作台上進行稱量；如果環境存在較多幹擾因素，則建議設置單獨的稱量間以提高測量的准確性和可靠性。同時，無論在何種環境下使用天平，都應嚴格遵守操作規範，確保實驗結果的准確性和可重複性。

 A JAPANESE AT HIS TOILET FOR A VISIT OF CEREMONY. A JAPANESE AT HIS TOILET FOR A VISIT OF CEREMONY. Top-side Galah! I prompted Camille to ask if he had ever encountered Ned Ferry, and he laughed. "But if she should be at Wiggins--" "And there is the whole trouble," I added. "She will not let you marry the woman whose--" A port crowded with steamers taking in coal, and very light barks high out of the water, kept in equilibrium by parallel outriggers at the ends of two flexible spars. These crank boats, made of[Pg 124] planks that scarcely overlap, were piled with luggage, and the boatmen jostle and turn and skim close under the fast-steaming transatlantic liners, amid a bewildering babel of shouts and oaths, under a sun hot enough to melt lead.     97 “You tell me who knew the way to get into the captain’s safe and I’ll try to get the emeralds.”  The reporter interposed that it was the act of men maddened by grief and their losses. [Pg 86] He turned his chair and studied her in a kind of hopeless amusement. "Felipa," he said, "if you will insist upon being told, I cut open the pockets of those dead men's clothes with it."  JOSIAH KLEGG, ESQ.,  "Did you raid the establishment of a person named"  "You drunken maverick," answered Billings, trying to brave it out. "I'll have you shot for insultin' and threatenin' your sooperior officer. Skip out o' here before the Provo comes up and ketches you. Let me go on about my business. Forward, boys."    "Of course you did. I—I gave myself away. I pleaded with you." That same day, Calverley summoned, or rather packed, a jury at which he himself presided; and a verdict of wilful murder was returned against Edith. Apprehensive, however, that the charge of poisoning might not be sustained upon the unsupported testimony of Mary Byles, he easily influenced the credulous jurors to believe that witchcraft had as much to do with the child's death as poison. His usual tact, however, had forsaken him on this occasion, and it was not until the verdict was announced and recorded, that the unwelcome conviction flashed across his mind, that the temporal courts could exercise no jurisdiction over the crime of witchcraft. It was now too late to alter the language of the inquisition. It had gone forth to hundreds who awaited its promulgation with intense anxiety; and the language of the verdict that "Edith Holgrave delivered to Mary Byles, a certain charmed or poisonous drug, for the purpose of destroying Roland De Boteler, and which said drug was administered to, and caused the death of, the said Roland," was, in a few hours, familiar to the whole town and neighbourhood.  Xi extends condolences over Hong Kong building fire, urges all-out rescue efforts to minimize losses
(Xinhua) 08:02, November 27, 2025
BEIJING, Nov. 26 (Xinhua) -- Chinese President Xi Jinping on Wednesday extended condolences over a deadly residential building fire in Hong Kong, which killed at least 13 people.

Xi, also general secretary of the Communist Party of China (CPC) Central Committee and chairman of the Central Military Commission, expressed sympathy to the families of the victims and those affected by the disaster. He urged all-out efforts to extinguish the fire and minimize casualties and losses.

In the wake of the fire, Xi attached great importance to the accident and immediately sought updates on the rescue efforts and casualties.

Xi instructed the director of the Liaison Office of the Central People's Government in the Hong Kong Special Administrative Region (HKSAR) to convey his condolences and sympathies to HKSAR Chief Executive John Lee.

He required the Hong Kong and Macao Work Office of the CPC Central Committee and the liaison office to support the HKSAR government in making all-out efforts to put out the fire, do everything possible in search and rescue, treat the injured, and comfort the victims' families.

China releases white paper on arms control in new era
(Xinhua) 10:19, November 27, 2025
BEIJING, Nov. 27 (Xinhua) -- China's State Council Information Office on Thursday released a white paper titled "China's Arms Control, Disarmament, and Nonproliferation in the New Era."

The white paper said that China plays a constructive role in international arms control, disarmament, and nonproliferation, and actively offers its initiatives and solutions.

China has been and will always be a builder of world peace, a contributor to global development, and a defender of the international order, it said.

The white paper was released to comprehensively present China's policies and practices on arms control, disarmament, and nonproliferation, and its position on security governance in emerging fields such as outer space, cyberspace, and artificial intelligence.

It was also to restate China's commitment to safeguarding world peace and security, and to call on countries around the world to work together for international arms control.

The white paper noted that China is committed to upholding the international arms control regime with the United Nations (UN) at its core. It works to promote global governance in arms control, supports all efforts to build a world of lasting peace and common security, and serves as a key promoter of international arms control.

It also noted that as a permanent member of the UN Security Council, China has actively safeguarded the authority and effectiveness of the international arms control regime, played a constructive role in multilateral arms control in the nuclear, biological, chemical and other fields, and conscientiously performed its duties prescribed by international arms control treaties, making its due contribution to international arms control.

Emerging fields such as outer space, cyberspace, and AI represent new frontiers for human development. They create a new focus of strategic security, and new territories of global governance, the white paper pointed out.

China proposes that with the universal participation of all countries, the UN should play a pivotal role in fostering a global governance framework and standards for emerging fields based on broad consensus, while increasing the representation and voice of developing countries, it added.

The white paper stressed that China continues to build its domestic nonproliferation capacity, actively participating in the international nonproliferation process, promoting international cooperation on peaceful uses of science and technology, and facilitating the improvement of global nonproliferation governance.

Chinese modernization follows the path of peaceful development, and China's growth contributes to the growth of the world's peaceful forces. China stands ready to work with all peace-loving countries to build an equal and orderly multipolar world and promote universally beneficial and inclusive economic globalization. It will consolidate and develop the UN-centered international arms control regime, work with all parties to build a community with a shared future for humanity, and create a brighter future for all, according to the white paper.
The Chinese Foreign Ministry on Tuesday said the atmosphere of the phone call between Chinese President Xi Jinping and U.S. President Donald Trump on Monday was "positive, friendly, and constructive."
