重量减轻

SUGGESTED MODIFICATIONS Among the suggestions put forward by various commanders for modifying the 81-mm so as to make it more useful to the infantry regiment there were the following: Lighten it in "any manner possible" to increase its cross-country mobility. Build it so that it could be broken down from a long barrel to a short barrel, thus making a lighter pack possible while preserving its heavy punch at the short ranges. Sectionalize the base plate so that the load can be distributed. Alter metallurgically or in design the elevating screw, the breaking and rapid wearing of which is now the chief structural weakness in the weapon.

建议采取的改进措施：为改进81mm迫击炮，使其在步兵团中发挥更大的战术校能，多位指挥官提出了如下意见：尽一切办法减轻重量，以增强其越野机动性；改进结构，使长炮管可拆解更换为短炮管，这样就可以在保留强大的近程冲击力的同时减轻负重；分段铸造底盘，使负重均匀分布；改进升降螺丝杆的冶炼或设计，升降螺丝杆的损坏和迅速磨损现在是这种武器主要的结构缺陷。

The hygienic and toxinfree Xinli PP-R pipes serial products are green and environmental construction materials, which have been recommended by the four ministries and commissions of the State Department, The products are heatresistant which means that the temperature of the supplied water can reach 95℃ under the specified long-term working hours, They are also corrosion-resistant and antiscale and can prevent any corrosion and rust in pipes, lavers and bathtubs.

&鑫利&PPR给水管系列产品，质量轻，20℃时的密度为0.89—0.91g/cm3，重量仅为钢管的九分之一，紫铜管的十分之一。由于重量轻，可大大减轻工人的施工强度。耐热性能好：瞬间使用水温可达95℃，长期使用时，当工作压力不大于0.6mpa时，水温可达75℃。这可满足一般生活、生产水温的需要，所以建筑给水PPR管一种较理想的热水管材。耐腐蚀性好：对水中的所有离子和建筑物内的化学物质均不起化学作用，不生锈、不会腐蚀。

The results showed that the use of tourmaline could increase alcoholic fermentation speed of molasses, the fermentation speed kept increasing with the increase of the use level of tourmaline, however, as its use level was above 11 %, the increase of fermentation speed was inevident; the use of tourmaline had no side-effects on the content of the main impurities including methanol, n-propyl alcohol, isobutyl alcohol, isoamyl alcohol; though it had weight loss after a period of use, it could still promote alcoholic fermentation of molasses.

结果表明，电气石对提高酵母酒精的发酵速率有促进作用，随着使用量的增加，发酵速率也随着提高，当使用量超过11 %时，发酵速率的继续提高不明显；电气石对发酵过程主要杂质甲醇、正丙醇、异丁醇、异戊醇等没有影响；电气石在使用一段时间后，重量减轻，但仍有促进发酵的作用。

"Increased sweating merely dehydrates 『脱水』you more quickly," says Otto. When you weigh yourself, that will appear as weight loss. But within twenty-four to thirty-six hours your body will return to normal hydration『水合作用』. It's simply a temporary water-weight loss that you're seeing.

奥托说：多流汗只会使你的身体加快脱水，称重量时看起来体重减轻了，但在24小时至36小时之内，你身体内部水合物会恢复到正常水平，你先前所看到的只是水的重量的减轻。

For example, movement of spool to change the seat of the movement, would be a straight line to change the angular displacement, so that the volume control valve smaller weight.

例如，将阀芯的移动改变为阀座的移动，将直线位移改变为角位移等，使控制阀体积缩小，重量减轻。

To overcome the drawbacks in the weight and cost of the antenna with the corrugated soft surface, a new patch antenna with patch rings is designed. Its weight is about 1/4 less than the antenna with the corrugated soft surface and it is inexpensive. Good experimental results are obtained. The radiation pattern of the antenna is more rotationally symmetric, and a more reduction on the sidelobe levels of the antenna is achieved as compared to the antenna with the corrugated soft surface. In conclusion, in the present thesis both theoretical and experimental research works have been carried out intensively on patch antennas based on photonic-bandgap structures.

为了克服皱褶软表面天线份量重，加工费用贵等缺点，我们对空气介质的皱褶圆环结构软表面天线进行了改进，将周期分布的皱褶圆环平面化，并保持结构的软表面特性，设计出了一种新的平面圆环结构的软表面天线并进行了实验研究，加工的平面圆环结构天线比皱褶圆环结构天线重量减轻了约1/4，加工费用大大降低，所取得的实验结果显示，该平面圆环结构软表面天线的方向图的轴对称性得到了改善，在俯仰角从0°～-90°的范围内天线H面的波束与E面重合，与皱褶圆环结构相比，天线的旁瓣和背瓣受到了更大的抑制，E面方向图上+120°方向的旁瓣被明显削弱。
