Since Would War II considerable advances have been made in the area of health-care services. These include better access to health care (particularly for the poor and minorities), improvements in physical plants, and increased numbers of physicians and other health personnel. All have played a part in the recent improvement in life expectancy (life expectancy: n.平均寿命(=expectation of life)). But there is mounting criticism of the large remaining gaps in access, unbridled cost inflation, the further fragmentation of service, excessive indulgence in wasteful high-technology “gadgeteering,” and a breakdown in doctor-patient relationships. In recent years (in recent years: 最近几年中) proposed panaceas and new programs, small and large, have proliferated at a feverish pace and disappointments multiply at almost the same rate. This has led to an increased pessimism—“everything has been tried and nothing works”—which sometimes borders on cynicism or even nihilism.
It is true that the automatic “pass through” of rapidly spiraling costs (spiraling costs: 螺旋式上升的费用) to government and insurance carriers, which was set in a publicized environment of “the richest nation in the world,” produced for a time (for a time: adv.暂时, 一度) a sense of unlimited resources and allowed to develop a mood whereby every practitioner and institution could “do his own thing” without undue concern for the “Medical Commons.” The practice of full-cost reimbursement encouraged capital investment and now the industry is overcapitalized. Many cities have hundreds of excess hospital beds; hospitals have proliferated a superabundance of high-technology equipment; and structural ostentation and luxury were the order of the day (order of the day: 议程,<口>流行的事物,风尚). In any given day, one-fourth of all community beds are vacant; expensive equipment is underused or, worse, used unnecessarily. Capital investment brings rapidly rising operating costs (operating costs: 生产费用,营业成本).
Yet, in part, this pessimism derives from expecting too much of health care. It must be realized that care is, for most people, a painful experience, often accompanied by fear and unwelcome results. Although there is vast room for improvement, health care will always retain some unpleasantness and frustration. Moreover, the capacities of medical science are limited. Humpty Dumpty (一经损坏无法修复的东西) cannot always be put back together again. Too many physicians are reluctant to admit their limitations to patients; too many patients and families are unwilling to accept such realities. Nor is it true that everything has been tried and nothing works, as shown by the prepaid group practice plans of the Kaiser Foundation and at Puget Sound. In the main (in the main: adv.大体上), however, such undertakings have been drowned by a veritable flood of public and private moneys which have supported and encouraged the continuation of conventional practices and subsidized their shortcomings on a massive, almost unrestricted scale. Except for the most idealistic and dedicated, there were no incentives to seek change or to practice self-restraint or frugality. In this atmosphere, it is not fair to condemn as failures all attempted experiments; it may be more accurate to say many never had a fair trial.

Behavior is one of two general responses available to endothermic (endothermic: adj.吸热(性)的,[动]温血的) (warm-blooded) species for the regulation of body temperature, the other being innate (reflexive) mechanisms of heat production and heat loss. Human beings rely primarily on the first to provide a hospitable thermal microclimate (microclimate: n.[气]小气候(指森林、城市、洞穴等局部地区的气候)) for themselves, in which the transfer of heat between the body and the environment is accomplished with minimal involvement of innate mechanisms of heat production and loss. Thermoregulatory (thermoregulatory: adj.体温调节的,保持(一定)体温的) behavior anticipates hyperthermia, and the organism adjusts its behavior to avoid becoming hyperthermic: it removes layers of clothing, it goes for a cool swim, etc. The organism can also respond to changes in the temperature of the body core, as is the case during exercise; but such responses result from the direct stimulation of thermoreceptors distributed widely within the central nervous system (central nervous system: n. 中枢神经系统), and the ability of these mechanisms to help the organism adjust to gross changes in its environment is limited.
Until recently it was assumed that organisms respond to microwave radiation in the same way that they respond to temperature changes caused by other forms of radiation. After all, the argument runs, microwaves are radiation and heat body tissues. This theory ignores the fact that the stimulus to a behavioral response is normally a temperature change that occurs at the surface of the organism. The thermoreceptors that prompt behavioral changes are located within the first millimeter of the skin’s surface, but the energy of a microwave field (microwave field: 超高频场, 微波场) may be selectively deposited in deep tissues, effectively bypassing these thermoreceptors, particularly if the field is at near-resonant frequencies. The resulting temperature profile (temperature profile: 温度曲线图, 温度轮廓) may well be a kind of reverse thermal gradient in which the deep tissues are warmed more than those of the surface. Since the heat is not conducted outward to the surface to stimulate the appropriate receptors, the organism does not “appreciate” this stimulation in the same way that it “appreciates” heating and cooling of the skin. In theory (in theory: 理论上), the internal organs of a human being or an animal could be quite literally cooked well-done (well-done: adj.做得好的, 完全煮熟的) before the animal even realizes that the balance of its thermomicroclimate has been disturbed.
Until a few years ago, microwave irradiations at equivalent plane-wave power densities of about 100 mW/cm2 were considered unequivocally to produce “thermal” effects; irradiations within the range of 10 to 100 mW/cm2 might or might not produce “thermal” effects; while effects observed at power densities below 10 mW/cm2 were assumed to be “nonthermal” in nature. Experiments have shown this to be an oversimplification, and a recent report suggests that fields as weak as 1 mW/cm2 can be thermogenic. When the heat generated in the tissues by an imposed radio frequency (radio frequency: n.无线电频率) (plus the heat generated by metabolism) exceeds the heat-loss capabilities of the organism, the thermoregulatory system has been compromised. Yet surprisingly, not long ago (not long ago: adv.不久前), an increase in the internal body temperature was regarded merely as “evidence” of a thermal effect.

Agricultural progress provided the stimulus necessary to set off (set off: v.引起, 使爆发) economic expansion in medieval France. As long as those who worked the land were barely able to ensure their own subsistence (the minimum (as of food and shelter) necessary to support life) and that of their landlords, all other activities had to be minimal, but when food surpluses increased, it became possible to release more people for governmental, commercial, religious and cultural pursuits.
However, not all the funds from the agricultural surplus were actually available for commercial investment. Much of the surplus, in the form of food increases, probably went to raise the subsistence level; an additional amount, in the form of currency gained from the sale of food, went into the royal treasury to be used in waging war. Although Louis VII of France levied a less crushing tax burden on his subjects than did England’s Henry II, Louis VII did spend great sums on an unsuccessful crusade, and his vassals—both lay and ecclesiastic—took over spending where their sovereign stopped. Surplus funds were claimed both by the Church and by feudal landholders, whereupon (1: on which; 2: closely following and in consequence of which) cathedrals and castles mushroomed throughout France.
The simultaneous progress of cathedral building and, for instance, vineyard expansion in Bordeaux (Bordeaux: n.波尔多葡萄酒) illustrates the very real competition for available capital between the Church and commercial interests; the former produced inestimable moral and artistic riches, but the latter had a stron
