(1)The snow dimple occurs several days after the fresh snow wore it on zarame snow and be repeating occurrence and disappearance many times a winter.(2)The period from the snowfall to the snow disappear inside the tank that the layer of the snow is done unstably by the obstacle were 3 to 13 days, average 7.25th.(3)Melting snow water needs to snake it over, because it has frozen without coming off by surface tension when the roof slope is 20 or less degree.(4)As for the roof slope about 30 degree are practical, because the crown snow becomes easy to fall when it suddenly does it too much, although it is good to do suddenly and cause faced the south.(5)The melting snow performance of the ventilation melting snow construction method roof Is 6.7〜10.5kg/(m^2/day).(6)The resistance snow power of 210kg/m^2 is needed to make the architecture structure in the area of ground snow 1〜2m, and 420kg/m^2 in the area of m,630kg/m^2 over in the area of snow 3〜4m.(7)In the Hokuriku 4 prefecture where the highest in the past snow high is 1〜4 in the receiving of a benefit family becomes 1,330,000 family (72.7%) and the receiving of a benefit population becomes 4,130,000 people (73.6%).(8)Without being overconfident we need to rigidly enforce the YUKIOROSHI, when the heavy snowfall year, abnormal snowfall, abnormal low temperatures, incline load etc. were seen.

（1）下雪发生在新鲜的雪上几天后发生在扎拉姆雪上，在冬天重复发生并多次消失和消失。（2）从降雪到积雪的阶段消失在储罐内，障碍物的障碍不变的雪层是3到13天，平均雪差异7.25，因为它可以越来越多地融化。学位。（4）至于屋顶坡度约30度是实用的，因为突然突然做得太多时，皇冠雪变得容易掉落，尽管突然突然做并导致南部面对面。（5）通风融化降雪方法的融化降雪屋顶屋顶的融化融化屋顶屋顶的熔融融化为6.7-10.5kg/（M^2/day）（m^2/day）（m^2/day）。 1-2m和420kg/m^2在M的面积为630kg/m^2的降雪面积为3-4m。（7）在Hokuriku 4中，过去的降雪中最高的降雪中最高的是1-4个受益家庭的1-4是受益家庭的1,330,000个家庭（72.7％），而受益人的人数（72.7％）不得超过4,130,000人（7.130，000％）（73.6％）（73.6％）（83.6％）（8）。强制执行Yukioroshi，当发现大雪年，异常降雪，低温，倾斜负荷等时。
