发帖数: 138 | 1 NBME5, Block 4 Q46: FRC occurs where the sum of the 2 pressures (inward pull
of lung and outward pull of chest wall) are equal and opposite, so only
answer D (2L) shows this balance. |

发帖数: 179 | 2 Thanks for the previous explanations. However, in a second thought, I tend
to stick to my original answer.
My explanation to this is as following:
at FRC, the PRESSURE of inward (lung) and outward (chest wall) equals to
zero. But that doesn't mean the VOLUME is the same. In fact, because of the
recoil, the pressure of the lung is almost always positive (at FRC, pressure
of the lung=+5). On the other hand, the chest wall always springs out,
therefore the pressure is always negative (at FRC, press... 阅读全帖 |

发帖数: 5763 | 6 "噢，那正是我要找的石头"
作者：杨振宁/刘兵 译
沃纳·海森堡（Werner Heisenberg）是历史上最伟大的物理学家之一。
当他作为一个年轻的研究者开始工作时，物理学界正处于一种非常混乱而且令人灰
心丧气的状态，对此，A·派斯曾用狄更斯在《双城记》中的话，将其描述为："这是希
望的春天，这是绝望的冬天"。
人们在做的是一场猜谜游戏：纯粹是通过直觉，一次又一次地，有人提出一些临时
方案，惊人地解释了光谱物理学中某些规则，这些了不起的成就会让人欢欣鼓舞。可是
进一步的工作总是揭示出新方案的自相矛盾或不完善，于是又带来了失望。在最后的光
明到来之前的那些年月中，这种司空见惯的起伏不定典型地反映在W·保利在1925年前
后四个月中写给R·克罗尼希的两封信中：
物理再一次走入了死胡同。至少对我来说，物理是太困难了。
海森堡的力学让我恢复了对生活的兴趣。
在第二封信中，保利提到的是海森堡在1925年夏天所做的工作。不过这一次与以前
那些充满欢欣与希望但又总是给人带来失望的时期不同，这是物理学中一个新时代的开
端。因为就在保利写这两封信之间的那段时间，海森堡独自在赫里戈兰渡假时，得到了

发帖数: 2511 | 26 I3.基督新教的不同宗派怎样看洗礼
今次介绍的，是基督教（以香港通俗的说法，包括新教、改革教、福音派等）如何看一
些宗教礼仪。
天主教朋友都听过，「基督教」只有两个圣礼或者礼仪，就是「洗礼」（或称圣洗，浸
信派称为「浸礼」，Baptism）和「主餐」（Holy Communion，The Lord's Supper，圣
餐礼，天主教和圣公会称Eucharist）。
Ａ）浸礼／圣洗／洗礼（Baptism）
很多所谓「基督教」书（相信主要是福音派）普遍宣称「基督教」的 Baptism是指「信
而受洗」，只有象征意义。
其实，信义宗和圣公会对「圣洗」保留了很多和罗马天主教相似的特色，甚至仪式也很
相似。
「圣洗」方面，信义宗、荷兰改革宗、长老会、圣公会、循道宗都接受婴儿洗礼，认为
除了象征意义，也包括神的工作。部份宗派如信义宗也信婴孩是有「信 」的。他们也
认为在洗礼里面，神有特别的工作，具有恩典和拯救的功能，并且是旧约婴孩出生后行
割礼归入神家而在新约的表记。篇幅所限，我不能多介绍。
福音派（主要浸信派）因为觉得婴孩是有「信 」的说法不合理，乃排拒之。他们认为

Along the Psalmist's music deep,
Now tell me if that any is,
For gift or grace, surpassing this:
